  3. Media and risk. A phase model elucidating media attention to nuclear energy risk

    In today's risk-filled society, it is vital to recognize not only the risks that we face every day, but also that knowledge of such risks spreads, above all, via mass media. Risk-related information contributes to our knowledge and affects how we perceive risks and what risk decisions we ultimately make. Among the most memorable disasters of risks taken in recent memory, the nuclear energy accident in Fukushima, Japan, in 2011 changed how the public, policymakers, and media outlets perceive and deliberate the risk of nuclear energy. In response, the research question of this study interrogates how media portrayed the risk of nuclear energy and how coverage of the technology changed after the accident at Fukushima. The study concentrates on how two Swiss newspapers covered nuclear energy between 2010 and early 2015. By using a broad definition of risk and an innovative empirical operationalization of the concept, the study identifies different risk attention phases in media coverage, each characterized by different focus on risk dimensions. Interestingly, results show that those media paid considerable attention to political decisions about the use of nuclear energy, and surprisingly, the detrimental dimension of risk was in focus even before the 2011 nuclear accident in Japan. Although the benefits of nuclear technology became obscured after Fukushima, they recuperated interest as early as a year later. Such results raise a question regarding risk decisions and the use of nuclear energy - namely, when do societies decide upon risks, and how do media portray the risk at that moment in time?

    2014-09-01

    Using a series of online self-report measures, we examine media multitasking, a particularly pervasive form of multitasking, and its relations to three aspects of everyday attention: (1) failures of attention and cognitive errors (2) mind wandering, and (3) attentional control with an emphasis on attentional switching and distractibility. We observed a positive correlation between levels of media multitasking and self-reports of attentional failures, as well as with reports of both spontaneous and deliberate mind wandering. No correlation was observed between media multitasking and self-reported memory failures, lending credence to the hypothesis that media multitasking may be specifically related to problems of inattention, rather than cognitive errors in general. Furthermore, media multitasking was not related with self-reports of difficulties in attention switching or distractibility. We offer a plausible causal structural model assessing both direct and indirect effects among media multitasking, attentional failures, mind wandering, and cognitive errors, with the heuristic goal of constraining and motivating theories of the effects of media multitasking on inattention.

    The uses of social media can be seen as driven by a search for affective intensity translating as moments of paying attention, no matter how brief these instances may be. In the framework of attention economy, attention has been discussed as a valuable commodity whereas distraction, involving both pleasurable entertainment and dissatisfactory disorientation, has been associated with cognitive overload and the erosive lack of focus. By discussing clickbait sites and Facebook in particular, thi...

  7. Media multitasking and behavioral measures of sustained attention.

    In a series of four studies, self-reported media multitasking (using the media multitasking index; MMI) and general sustained-attention ability, through performance on three sustained-attention tasks: the metronome response task (MRT), the sustained-attention-to-response task (SART), and a vigilance task (here, a modified version of the SART). In Study 1, we found that higher reports of media multitasking were associated with increased response variability (i.e., poor performance) on the MRT. However, in Study 2, no association between reported media multitasking and performance on the SART was observed. These findings were replicated in Studies 3a and 3b, in which we again assessed the relation between media multitasking and performance on both the MRT and SART in two large online samples. Finally, in Study 4, using a large online sample, we tested whether media multitasking was associated with performance on a vigilance task. Although standard vigilance decrements were observed in both sensitivity (A') and response times, media multitasking was not associated with the size of these decrements, nor was media multitasking associated with overall performance, in terms of either sensitivity or response times. Taken together, the results of the studies reported here failed to demonstrate a relation between habitual engagement in media multitasking in everyday life and a general deficit in sustained-attention processes.

    This study examines attention effects in the market for hybrid vehicles. We show that local media coverage, gasoline price changes and unprecedented record gasoline prices have a significant causal impact on the consumers' attention. As attention is not directly observable, we analyze online search behavior as a proxy for the revealed consumer attention. Our study is based on weekly panel data of local newspaper coverage, gasoline prices and Google search trends for 19 metropolitan areas in the US. Additionally, we use monthly state-level panel data to show that the adoption rate of the hybrid vehicle technology is robustly related to our measure of attention.

  9. Media and attention, cognition, and school achievement.

    2008-01-01

    Marie Evans Schmidt and Elizabeth Vandewater review research on links between various types of electronic media and the cognitive skills of school-aged children and adolescents. One central finding of studies to date, they say, is that the content delivered by electronic media is far more influential than the media themselves. Most studies, they point out, find a small negative link between the total hours a child spends viewing TV and that child's academic achievement. But when researchers take into account characteristics of the child, such as IQ or socioeconomic status, this link typically disappears. Content appears to be crucial. Viewing educational TV is linked positively with academic achievement; viewing entertainment TV is linked negatively with achievement. When it comes to particular cognitive skills, say the authors, researchers have found that electronic media, particularly video games, can enhance visual spatial skills, such as visual tracking, mental rotation, and target localization. Gaming may also improve problem-solving skills. Researchers have yet to understand fully the issue of transfer of learning from electronic media. Studies suggest that, under some circumstances, young people are able to transfer what they learn from electronic media to other applications, but analysts are uncertain how such transfer occurs. In response to growing public concern about possible links between electronic media use and attention problems in children and adolescents, say the authors, researchers have found evidence for small positive links between heavy electronic media use and mild attention problems among young people but have found only inconsistent evidence so far for a link between attention deficit hyperactivity disorder and media use. The authors point out that although video games, interactive websites, and multimedia software programs appear to offer a variety of possible benefits for learning, there is as yet little empirical evidence to suggest that

    Television viewers' attention is increasingly more often divided between television and "second screens", for example when viewing television broadcasts and following their related social media discussion on a tablet computer. The attentional costs of such multitasking may vary depending on the ebb and flow of the social media channel, such as its emotional contents. In the present study, we tested the hypothesis that negative social media messages would draw more attention than similar positive messages. Specifically, news broadcasts were presented in isolation and with simultaneous positive or negative Twitter messages on a tablet to 38 participants in a controlled experiment. Recognition memory, gaze tracking, cardiac responses, and self-reports were used as attentional indices. The presence of any tweets on the tablet decreased attention to the news broadcasts. As expected, negative tweets drew longer viewing times and elicited more attention to themselves than positive tweets. Negative tweets did not, however, decrease attention to the news broadcasts. Taken together, the present results demonstrate a negativity bias exists for social media messages in media multitasking; however, this effect does not amplify the overall detrimental effects of media multitasking.

    Media attention to genetically modified (GM) foods has been described as negative, especially in Europe. At the turn of the century appreciation of GM foods was at an all-time low in Europe. Food manufacturers are still careful in the use, development and communication of GM based food products, and their caution influences innovation processes. In this study we explore the link between media attention and innovation practice. Media attention to three specific high-profile GM food cases is described and linked to innovation practice. We elucidate the order of events in these cases and show that publics could only to a limited extent have formed an opinion on GM based food products based on scientifically valid data through written English media. Innovators in food biotechnology may benefit from this knowledge for future product development and marketing, and we suggest that innovation may benefit from early stakeholder involvement and communication activities.

    , but also its mere success means that stories framing green businesses in a negative light become newsworthy while positive stories lose their newsworthiness. Therefore, and despite a large and loyal customer base, many green companies now find themselves in a much more hostile environment than a decade ago.......There are signs that a general counter-attack is now being orchestrated against the greens. This paper surveys the evidence regarding an issue-attention cycle in environmental concern in Western Europe and North America. It furthermore discusses the role of the news media in creating the cycle....... It is well documented that the mass media plays an important role in determining which issues receive high or low attention by the general public. However, not only does the media's assessment of what is newsworthy mean that green businesses will eventually lose the current of a rising issue attention cycle...

    Full Text Available This manuscript presents two experiments designed to explore the effects of attention on perceived exertion and time to failure in a fatiguing athletic task. There were two major motivating factors for these experiments. First, there are few studies evaluating attentional focus effects in endurance tasks and, second, there is a lack of integration between studies of attentional focus as external/internal (e.g., Wulf, 2007 compared to associative/dissociative (e.g., Stevenson & Biddle, 1998. In Experiment 1, we used a fatiguing wall-sit posture (essentially a complex, isometric task to compare two different types of external attention with an internal focus on the position of the legs. An external focus (regardless of type increased the time taken to failure and reduced perceived exertion. In Experiment 2, we manipulated subjects’ expectancy of fatigue to test the interaction of attention and expectancy (both top-down factors in this highly fatiguing task. Previous theories of attention during endurance tasks have suggested that as fatigue/pain increase, bottom-up factors begin to dominate subjects’ attention. While this may be true, Experiment 2 showed that even in a highly fatiguing task, attentional strategies and expectancies affected the time to failure and perceived exertion.

  15. The role of attention problems and impulsiveness in media violence effects on aggression.

    Previous research has established media violence as a causal risk factor for aggressive behavior. Several theoretical mechanisms have been identified to explain this effect. The present study assessed 422 undergraduate students to test the possibility that individual differences in attention problems and impulsiveness can help explain the link between violent media and aggression. Attention problems and impulsiveness proved to be a distinct construct from other processes believed to mediate aggression (aggressive beliefs, aggression related schemata, trait anger, and trait hostility). Attention problems and impulsiveness were uniquely related to both media exposure (total weekly hours and violent content) and aggression. Attention problems and impulsiveness were particularly related to impulsive (as opposed to premeditated) aggression. These results suggest that attention problems and impulsiveness may play an important role in violent media effects on aggression. © 2014 Wiley Periodicals, Inc.

  16. Attentional Focusing Instructions and Force Production

    2011-01-01

    Full Text Available Research progress assessing the role of attentional focusing instructions on skill acquisition and performance has lead researchers to apply this approach to force production tasks. Initial converging evidence indicates that force production tasks are sensitive to verbal instruction; externally focused instructions (onto movement outcomes, or onto the object force is being exerted against are shown to be more beneficial than internally focused instructions (focusing attention onto the movements being executed. These benefits are observed for maximal and accurate force production, as well as the maintenance of force production in prolonged tasks. A range of mechanisms are identified supporting the proposal that an external focus promotes movement efficiency in line with energy and effort conservation. Future research is required to assess how this developing body of work interacts with the broader understanding of psychological and physiological factors implicated in the effective production, maintenance and limitation of maximal or sub-maximal forces.

    Selective visual attention involves prioritizing both the location (orienting) and distribution (focusing) of processing. To date, much more research has examined attentional orienting than focusing. One of the most well-established findings is that orienting can be exogenous, as when a unique change in luminance draws attention to a spatial location (e.g., Theeuwes in Atten Percept Psychophys 51:599-606, 1992; Yantis and Jonides in J Exp Psychol Hum Percept Perform 10:601, 1984), and endogenous, as when a red distractor shape diverts attention when one is looking for a red target (e.g., Bacon and Egeth in Percept Psychophys 55:485-496, 1994; Folk et al. in J Exp Psychol Hum Percept Perform 18:1030, 1992). Here we ask whether attentional focusing-the broadening and contracting of prioritized processing-is influenced by the same two factors. Our methodology involved a dual-stream attentional blink task; participants monitored two spatially separated streams of items for two targets that could appear unpredictably either in the same stream or in opposite streams. The spatial distribution of attention was assessed by examining second-target accuracy in relation to inter-target lag and target location (same or opposite streams). In Experiment 1, we found that attentional contracting was more rapid when the targets differed in luminance from the distractor items. In Experiments 2 and 3, we found that the rate of attentional contracting was slower when there were task-relevant distractors in the stream opposite the first target. These results indicate that the rate of attentional focusing, like orienting, can be modulated by both exogenous and endogenous mechanisms.

Content is now co-produced, shared, classified, and rated by millions of people, while attention has become the ephemeral and valuable resource that everyone seeks to acquire. This talk will describe the ways through which social attention determines the production and consumption of content within both the scientific community and social media, how its dynamics can be used to predict the future, and its role in affecting the public agenda. Keylens Management Consultants at Dusseldorf has investigated the Status Quo of Social Media-activities and interpreted experiences from customer projects.

    Repeating the same target's features or spatial position, as well as repeating the same context (e.g. distractor sets) in visual search leads to a decrease of reaction times. This modulation can occur on a trial by trial basis (the previous trial primes the following one), but can also occur across multiple trials (i.e. performance in the current trial can benefit from features, position or context seen several trials earlier), and includes inhibition of different features, position or contexts besides facilitation of the same ones. Here we asked whether a similar implicit memory mechanism exists for the size of the attentional focus. By manipulating the size of the attentional focus with the repetition of search arrays with the same vs. different size, we found both facilitation for the same array size and inhibition for a different array size, as well as a progressive improvement in performance with increasing the number of repetition of search arrays with the same size. These results show that implicit memory for the size of the attentional focus can guide visual search even in the absence of feature or position priming, or distractor's contextual effects.

    Recent research suggests that frequently switching between various forms of media (i.e. 'media multitasking') is associated with diminished attentional abilities, a disconcerting result given the prevalence of media multitasking in today's society. In the present study, we sought to investigate the extent to which the deficits associated with frequent media multitasking can be temporarily ameliorated via a short-term mindfulness intervention previously shown to produce beneficial effects on the attentional abilities of normally functioning individuals. Consistent with previous work, we found: (1) that heavy media multitaskers showed generally poorer attentional abilities than light media multitaskers and (2) that all participants showed benefits from the short-term mindfulness intervention. Furthermore, we found that the benefits of the short-term mindfulness intervention were not equivalently large across participants. Instead, these benefits were disproportionately large in the heavy media multitaskers. While the positive outcomes were short-lived, this opens the possibility of performing long-term interventions with the goal of realizing lasting gains in this population.

    Recent motor control literature has demonstrated that using verbal instructions to direct a performer's attention externally (i.e., toward the movement outcome) enhances motor skill performance. The purpose of this study was to investigate how an athlete's focus of attention impacts kinematic performance of the snatch. Using a counterbalanced within-participant design, 12 competitively trained athletes (8 male and 4 female athletes) performed 2 instructional blocks of 3 snatch repetitions at 80% of their most recent training 1 repetition maximum. Blocks of internal and external instructions were given to the athlete in a random fashion. Results showed that, when focusing internally, athletes significantly (p ≤ 0.05) increased elbow velocity relative to focusing externally, whereas the external instructions significantly increased horizontal barbell velocity, relative to internal instructions. Additionally, an internal focus resulted in significantly larger barbell-cervical-hip angles at maximum height of the barbell compared with an external focus, indicating that the athletes squatted under the barbell too soon. This information adds to the literature suggesting small changes in coaching instructions can impact performance significantly. It is recommended that coaches use instructions that direct an athlete's attention externally, toward the movement outcome, rather than the action itself.

    Balance performance in the elderly is related to psychological factors such as attentional focus. We investigated the effects of internal vs. external focus of attention and fall history on walking stability in healthy older adults. Walking stability of twenty-eight healthy older adults was assessed by applying random unilateral decelerations on a split-belt treadmill and analysing the resulting balance recovery movements. The internal focus instruction was: concentrate on the movement of your legs, whereas the external focus instruction was: concentrate on the movement of the treadmill. In both conditions participants were asked to look ahead at a screen. Outcome measures were coefficient of variation of step length and step width, and characteristics of the centre of mass velocity time-series as analysed using statistical parametric mapping. Fall history was assessed using a questionnaire. After each perturbation participants required two to three strides to regain a normal gait pattern, as determined by the centre of mass velocity response. No effects were found of internal and external focus of attention instructions and fall history on any of the outcome measures. We conclude that, compared to an internal focus of attention instruction, external focus to the walking surface does not lead to improved balance recovery responses to gait perturbations in the elderly.

    [Purpose] The present study reviewed studies that examined the effects of attentional focus on balance. [Methods] Keywords such as "attentional", "focus", and "balance" were used to find relevant research papers in PubMed (www.ncbi.nlm.nih.gov/pubmed). Forty-five papers were found, and 18 of them were used for this study, excluding review papers and papers irrelevant to the topic of this study. [Results] Among the papers used for the review, the number of papers in which external focus produced effective outcomes was 15 (83.3%). The number of papers in which both external and internal focus produced effective outcomes was 2 (11.1%). The number of paper in which no instruction about attentional focus was effective was 1 (5.5%), and the number of papers in which internal focus was effective was zero. [Conclusion] This short review suggests clinical implications about how physical therapists can use attentional focus for balance rehabilitation of patients. Instructions about external focus of attention can generally be useful as a method to improve posture and balance control. Furthermore, the present reviews indicates that external focus of attention would be more useful in a rehabilitation stage in which the difficulty level of balance performance is gradually increased.

  8. Revenue Sources and Social Media Engagement Among Environmentally Focused Nonprofits

    Full Text Available This study examines social media efforts among environmentally focused nonprofits. A survey of environmentally focused nonprofits revealed that more than half of these organizations receive government funding. Prior research demonstrates social media is an efficient medium in which to simultaneously communicate with multiple stakeholders. However, stakeholder engagement is likely tied with the need to raise funds. From that basis, we discuss social media use among nonprofits and develop hypotheses about differences in social media use among organizations receiving government funds and those not receiving government funds. Our hypotheses are rooted in resource dependency theory (RDT and dialogic communication theory (DCT. We test our hypotheses on data from environmentally focused nonprofits by comparing the levels of social media engagement with varying levels of their total funding provided by government grants to determine if there is a correlation with the level of public engagement via social media. We find the level of engagement on the social media site Facebook is lower for government-funded environmental nonprofits than privately funded ones. The findings of reduced social media engagement and the dependence upon government funding versus private funding supports the precepts of resource dependency theory.

    "Media events" generate conditions of shared attention as many users simultaneously tune in with the dual screens of broadcast and social media to view and participate. We examine how collective patterns of user behavior under conditions of shared attention are distinct from other "bursts" of activity like breaking news events. Using 290 million tweets from a panel of 193,532 politically active Twitter users, we compare features of their behavior during eight major events during the 2012 U.S. presidential election to examine how patterns of social media use change during these media events compared to "typical" time and whether these changes are attributable to shifts in the behavior of the population as a whole or shifts from particular segments such as elites. Compared to baseline time periods, our findings reveal that media events not only generate large volumes of tweets, but they are also associated with (1) substantial declines in interpersonal communication, (2) more highly concentrated attention by replying to and retweeting particular users, and (3) elite users predominantly benefiting from this attention. These findings empirically demonstrate how bursts of activity on Twitter during media events significantly alter underlying social processes of interpersonal communication and social interaction. Because the behavior of large populations within socio-technical systems can change so dramatically, our findings suggest the need for further research about how social media responses to media events can be used to support collective sensemaking, to promote informed deliberation, and to remain resilient in the face of misinformation.

Using 290 million tweets from a panel of 193,532 politically active Twitter users, we compare features of their behavior during eight major events during the 2012 U.S. presidential election to examine how patterns of social media use change during these media events compared to “typical” time and whether these changes are attributable to shifts in the behavior of the population as a whole or shifts from particular segments such as elites. Compared to baseline time periods, our findings reveal that media events not only generate large volumes of tweets, but they are also associated with (1) substantial declines in interpersonal communication, (2) more highly concentrated attention by replying to and retweeting particular users, and (3) elite users predominantly benefiting from this attention. These findings empirically demonstrate how bursts of activity on Twitter during media events significantly alter underlying social processes of interpersonal communication and social interaction. Because the behavior of large populations within socio-technical systems can change so dramatically, our findings suggest the need for further research about how social media responses to media events can be used to support collective sensemaking, to promote informed deliberation, and to remain resilient in the face of misinformation.

  12. Observers' focus of attention in the simulation of self-perception.

    1977-01-01

    This research was designed to assess the effects of a manipulation of observers' focus of attention--from a focus on the actor to a focus on the actor's situation--upon observers' attributions of attitude to an actor in a simulation of a forced-compliance cognitive dissonance experiment. Observers induced through empathy instructions to focus attention on the actor's situation inferred less actor attitude positivity than did observers given no specific observational set. In addition, situation-focused observers inferred that the actor's attitude was directly related to reward magnitude, whereas actor-focused observers inferred that the actor's attitude was inversely related to reward magnitude. An extension of self-perception theory, offered as an interpretation of these and other results, suggested that motivation attribution made by actors and observers in dissonance and simulation studies are dependent on focus of attention. The attributions made by actor-focused observers simulate those of objectively self-aware actors and are based upon perceived intrinsic motivation; the attributions of situation-focused observers simulate those of subjectively self-aware actors and are based upon perceived extrinsic motivation.

    It is well known that auditory and visual onsets presented at a particular location can capture a person's visual attention. However, the question of whether such attentional capture disappears when attention is focused endogenously beforehand has not yet been answered. Moreover, previous studies have not differentiated between capture by onsets presented at a nontarget (invalid) location and possible performance benefits occurring when the target location is (validly) cued.

    2016-03-01

    Focus of attention and its effects on skilled motor performance has become an important line of research in the motor learning domain. Numerous studies have demonstrated that an external focus of attention (i.e., on the movement effect) enhances motor performance and learning relative to an internal focus (i.e., on body movements). Thus, small differences in the wording of instructions or feedback given by teachers can have a significant impact on the effectiveness and efficiency of motor skill performance. In this paper, we review some of the attentional focus studies that are relevant to ballet performance. In addition, we report the findings of a survey among professional ballet dancers (N = 53) that we conducted to determine their typical attentional focus while performing certain movements. The results showed that the majority adopted internal foci, or combinations of internal and external foci, most of the time. This suggests that there is room for improvement for performance and teaching. We provide examples of how external foci can be promoted in ballet practice.

    New metrics have been developed to assess the impact of research and provide an indication of online media attention and data dissemination. We aimed to describe online media attention of articles evaluating cancer treatments and identify the factors associated with high online media attention. We systematically searched MEDLINE via PubMed on March 1, 2015 for articles published during the first 6 months of 2014 in oncology and medical journals with a diverse range of impact factors, from 3.9 to 54.4, and selected a sample of articles evaluating a cancer treatment regardless of study design. Altmetric Explorer was used to identify online media attention of selected articles. The primary outcome was media attention an article received online as measured by Altmetric score (i.e., number of mentions in online news outlets, science blogs and social media). Regression analysis was performed to investigate the factors associated with high media attention, and regression coefficients represent the logarithm of ratio of mean (RoM) values of Altmetric score per unit change in the covariate. Among 792 articles, 218 (27.5%) received no online media attention (Altmetric score = 0). The median [Q1-Q3] Altmetric score was 2.0 [0.0-8.0], range 0.0-428.0. On multivariate analysis, factors associated with high Altmetric score were presence of a press release (RoM = 10.14, 95%CI [4.91-20.96]), open access to the article (RoM = 1.48, 95%CI [1.02-2.16]), and journal impact factor (RoM = 1.10, 95%CI [1.07-1.12]. As compared with observational studies, systematic reviews were not associated with high Altmetric score (RoM = 1.46, 95%CI [0.74-2.86]; P  = 0.27), nor were RCTs (RoM = 0.65, 95%CI [0.41-1.02]; P  = 0.059) and phase I/II non-RCTs (RoM = 0.58, 95%CI [0.33-1.05]; P  = 0.07). The articles with abstract conclusions favouring study treatments were not associated with high Altmetric score (RoM = 0.97, 95%CI [0.60-1.58]; P  = 0

    Focused attention has great impact on our quality of life. Our learning, social skills and even happiness are closely intertwined with our capacity for focused attention. Attention promotion is replete with examples of training-induced increases in attention capability, most of which rely on visual and auditory stimulation. Pure haptic stimulation to increase attention capability is rarely found. We show that accurate force control tasks with pure haptic feedback enhance short-term focused attention. Participants were trained by a force control task in which information from visual and auditory channels was blocked, and only haptic feedback was provided. The trainees were asked to exert a target force within a pre-defined force tolerance for a specific duration. The tolerance was adaptively modified to different levels of difficulty to elicit full participant engagement. Three attention tests showed significant changes in different aspects of focused attention in participants who had been trained as compared with those who had not, thereby illustrating the role of haptic-based sensory-motor tasks in the promotion of short-term focused attention. The findings highlight the potential value of haptic stimuli in brain plasticity and serve as a new tool to extend existing computer games for cognitive enhancement.

    Today, with the approach of the 21st century, attention is focused on multi-media communications combining computer, visual and audio technologies. This article discusses the communication media target and the technological problems constituting the nucleus of multi-media. The communication media is becoming an environment from which no one can escape. Since the media has such a great power, what is needed now is not to predict the future technologies, but to estimate the future world and take to responsibility for future environments.

    1996-08-01

    The goals of this study were: (1) to determine if 24-month-old children exposed to opioids show decreased focused attention during free play compared with children of the same age who were not prenatally exposed; (2) to identify medical and social risk factors other than drug exposure that are related to focused attention; and (3) to determine if mothers' teaching ability had an effect on attention. Focused attention was rated during a 3-minute free play session for 30 toddlers who were methadone-exposed and for 44 comparison toddlers. The mother teaching the child to use a toy was also rated separately from the free play session. There was no difference in focused attention of 24 month olds during free play based only on prenatal exposure. Despite group differences in medical and social risk factors, only maternal IQ was significantly related to focused attention. Maternal instruction was strongly related to focused attention and mediated the effects of maternal IQ on attention.

    We demonstrate light focusing through scattering media by introducing particle swarm optimization for modulating the phase wavefront. Light refocusing is simulated numerically based on the angular spectrum method and the circular Gaussian distribution model of the scattering media. Experimentally, a spatial light modulator is used to control the phase of incident light, so as to make the scattered light converge to a focus. The influence of divided segments of input light and the effect of the number of iterations on light intensity enhancement are investigated. Simulation results are found to be in good agreement with the theoretical analysis for light refocusing. (paper)

  7. Form or function: Does focusing on body functionality protect women from body dissatisfaction when viewing media images?

    2018-01-01

    We examined whether shifting young women's ( N =322) attention toward functionality components of media-portrayed idealized images would protect against body dissatisfaction. Image type was manipulated via images of models in either an objectified body-as-object form or active body-as-process form; viewing focus was manipulated via questions about the appearance or functionality of the models. Social comparison was examined as a moderator. Negative outcomes were most pronounced within the process-related conditions (body-as-process images or functionality viewing focus) and for women who reported greater functionality comparison. Results suggest that functionality-based depictions, reflections, and comparisons may actually produce worse outcomes than those based on appearance.

    2013-01-01

    Full Text Available Whereas considerable developmental memory research has examined the contributions of short-term memory, processing efficiency, retention duration, and scope of attention to complex memory span, little is known about the influence of controlled attention. The present study investigated the relative influence of three understudied attention mechanisms on the verbal working memory span of school-age children: memory updating; attention focus switching; and sustained attention. Results of general linear modeling revealed that, after controlling for age, only updating accuracy emerged as a significant predictor of verbal working memory span. Memory updating speed (that subsumed attention focus switching speed also contributed but was mediated by age. The results extend the developmental memory literature by implicating the mechanism of memory updating and developmental improvement in speed of attention focus switching and updating as critical contributors to children’s verbal working memory. Theoretically, the results provide substantively new information about the role of domain-general executive attention in children’s verbal working memory.

    The present study examined whether the learning benefits of an external focus of attention (i.e., on the movement effect) relative to an internal focus (i.e. on the movement), found previously in non-disabled children and adults would also be found in children with intellectual disabilities (IDs). Participants (n = 24; average age: 12.2 years) with mild intellectual deficiency (IQ = 51-69) practiced throwing beanbags at a target. In the external focus group, participants were instructed to direct their attention to the movement of the beanbag, while in the internal focus group, participants were asked to direct their attention to the movement of their hand. The practice phase consisted of 40 trials, and attentional focus reminders were given after every third trial. Learning was assessed 1 day later by retention and transfer (greater target distance) tests, each consisting of 10 trials. No focus reminders were given on that day. The external focus group demonstrated more effective learning than the internal focus group, as evidenced by more accurate tosses on the transfer test. The present findings show that instructions that induce an external focus of attention can enhance motor learning in children with IDs. © 2012 The Authors.

    MacMahon, Clare; Charness, Neil

    2014-04-01

    This study investigated the nature of automaticity in everyday tasks by testing handwriting performance under single and dual-task conditions. Item familiarity and hand dominance were also manipulated to understand both cognitive and motor components of the task. In line with previous literature, performance was superior in an extraneous focus of attention condition compared to two different skill focus conditions. This effect was found only when writing with the dominant hand. In addition, performance was superior for high familiarity compared to low familiarity items. These findings indicate that motor and cognitive familiarity are related to the degree of automaticity of motor skills and can be manipulated to produce different performance outcomes. The findings also imply that the progression of skill acquisition from novel to novice to expert levels can be traced using different dual-task conditions. The separation of motor and cognitive familiarity is a new approach in the handwriting domain, and provides insight into the nature of attentional demands during performance.

  13. The Focus of Attention in Visual Working Memory: Protection of Focused Representations and Its Individual Variation.

    Heuer, Anna; Schubö, Anna

    2016-01-01

    Visual working memory can be modulated according to changes in the cued task relevance of maintained items. Here, we investigated the mechanisms underlying this modulation. In particular, we studied the consequences of attentional selection for selected and unselected items, and the role of individual differences in the efficiency with which attention is deployed. To this end, performance in a visual working memory task as well as the CDA/SPCN and the N2pc, ERP components associated with visual working memory and attentional processes, were analysed. Selection during the maintenance stage was manipulated by means of two successively presented retrocues providing spatial information as to which items were most likely to be tested. Results show that attentional selection serves to robustly protect relevant representations in the focus of attention while unselected representations which may become relevant again still remain available. Individuals with larger retrocueing benefits showed higher efficiency of attentional selection, as indicated by the N2pc, and showed stronger maintenance-associated activity (CDA/SPCN). The findings add to converging evidence that focused representations are protected, and highlight the flexibility of visual working memory, in which information can be weighted according its relevance.

  14. No arousal-biased competition in focused visuospatial attention.

    Ásgeirsson, Árni Gunnar; Nieuwenhuis, Sander

    2017-11-01

    Arousal sometimes enhances and sometimes impairs perception and memory. A recent theory attempts to reconcile these findings by proposing that arousal amplifies the competition between stimulus representations, strengthening already strong representations and weakening already weak representations. Here, we report a stringent test of this arousal-biased competition theory in the context of focused visuospatial attention. Participants were required to identify a briefly presented target in the context of multiple distractors, which varied in the degree to which they competed for representation with the target, as revealed by psychophysics. We manipulated arousal using emotionally arousing pictures (Experiment 1), alerting tones (Experiment 2) and white-noise stimulation (Experiment 3), and validated these manipulations with electroencephalography and pupillometry. In none of the experiments did we find evidence that arousal modulated the effect of distractor competition on the accuracy of target identification. Bayesian statistics revealed moderate to strong evidence against arousal-biased competition. Modeling of the psychophysical data based on Bundesen's (1990) theory of visual attention corroborated the conclusion that arousal does not bias competition in focused visuospatial attention.

    The purpose of this study was to investigate the relationships among self-focused attention, mindfulness and distress caused by the voices in psychiatric patients. Fifty-one individuals with a psychiatric diagnosis participated in this study. The Psychotic Symptom Rating Scale (PSYRATS) emotional factor was applied to measure the distress caused by the voices, the Self-Absorption Scale (SAS) was given for measuring the levels of self-focused attention, and the Mindful Attention Awareness Scale (MAAS) was used to measure mindfulness. The results showed that distress caused by the voices correlated positively with self-focused attention (private and public) and negatively with mindfulness. A negative correlation was also found between mindfulness and self-focused attention (private and public). Finally, multiple linear regression analysis showed that public self-focus was the only factor predicting distress caused by the voices. Intervention directed at diminishing public self-focused attention and increasing mindfulness could improve distress caused by the voices.

    The synchronization of loosely coupled chaotic systems has increasingly found applications to large networks of differential equations and to models of continuous media. These applications are at the core of the present Focus Issue. Synchronization between a system and its model, based on limited observations, gives a new perspective on data assimilation. Synchronization among different models of the same system defines a supermodel that can achieve partial consensus among models that otherwise disagree in several respects. Finally, novel methods of time series analysis permit a better description of synchronization in a system that is only observed partially and for a relatively short time. This Focus Issue discusses synchronization in extended systems or in components thereof, with particular attention to data assimilation, supermodeling, and their applications to various areas, from climate modeling to macroeconomics.

  17. Behavioral decoding of working memory items inside and outside the focus of attention.

    Mallett, Remington; Lewis-Peacock, Jarrod A

    2018-03-31

    How we attend to our thoughts affects how we attend to our environment. Holding information in working memory can automatically bias visual attention toward matching information. By observing attentional biases on reaction times to visual search during a memory delay, it is possible to reconstruct the source of that bias using machine learning techniques and thereby behaviorally decode the content of working memory. Can this be done when more than one item is held in working memory? There is some evidence that multiple items can simultaneously bias attention, but the effects have been inconsistent. One explanation may be that items are stored in different states depending on the current task demands. Recent models propose functionally distinct states of representation for items inside versus outside the focus of attention. Here, we use behavioral decoding to evaluate whether multiple memory items-including temporarily irrelevant items outside the focus of attention-exert biases on visual attention. Only the single item in the focus of attention was decodable. The other item showed a brief attentional bias that dissipated until it returned to the focus of attention. These results support the idea of dynamic, flexible states of working memory across time and priority. © 2018 New York Academy of Sciences.

    This study analyzes the issue attention cycle for print and online media coverage of a scientific publication examining the deaths of Chinese factory workers due to lung damage from chronic exposure to nanoparticles. The results of the nanoparticle study, published in 2009, embody news values that would make the study a prime candidate for press coverage, namely, novelty, negativity, controversy, and potential widespread impact. Nevertheless, mentions of the event in traditional English-language print media were nearly nonexistent. Online media, on the other hand, gave the story greater coverage. This case study exemplifies why online media may not be bound to the same issue attention cycle that print media are for controversial scientific events.

    Falls represent a substantial risk in the elderly. Previous studies have found that a focus on the outcome or effect of the movement (external focus of attention) leads to improved balance performance, whereas a focus on the movement execution itself (internal focus of attention) impairs balance performance in elderly. A shift toward more conscious, explicit forms of motor control occurs when existing declarative knowledge is recruited in motor control, a phenomenon called reinvestment. We investigated the effects of attentional focus and reinvestment on gait stability in elderly fallers and nonfallers. Full body kinematics was collected from twenty-eight healthy older adults walking on a treadmill, while focus of attention was manipulated through instruction. Participants also filled out the Movement Specific Reinvestment Scale (MSRS) and the Falls Efficacy Scale International (FES-I), and provided details about their fall history. Coefficients of Variation (CV) of spatiotemporal gait parameters and Local Divergence Exponents (LDE) were calculated as measures of gait variability and gait stability, respectively. Larger stance time CV and LDE (decreased gait stability) were found for fallers compared to nonfallers. No significant effect of attentional focus was found for the gait parameters, and no significant relation between MSRS score (reinvestment) and fall history was found. We conclude that external attention to the walking surface does not lead to improved gait stability in elderly. Potential benefits of an external focus of attention might not apply to gait, because walking movements are not geared toward achieving a distinct environmental effect. © 2017 The Authors.

    Moore, Katherine Sledge; Weissman, Daniel H

    2010-08-01

    In the present study, we investigated whether involuntarily directing attention to a target-colored distractor causes the corresponding attentional set to enter a limited-capacity focus of attention, thereby facilitating the identification of a subsequent target whose color matches the same attentional set. As predicted, in Experiment 1, contingent attentional capture effects from a target-colored distractor were only one half to one third as large when subsequent target identification relied on the same (vs. a different) attentional set. In Experiment 2, this effect was eliminated when all of the target colors matched the same attentional set, arguing against bottom-up perceptual priming of the distractor's color as an alternative account of our findings. In Experiment 3, this effect was reversed when a target-colored distractor appeared after the target, ruling out a feature-based interference account of our findings. We conclude that capacity limitations in working memory strongly influence contingent attentional capture when multiple attentional sets guide selection.

    The distribution of visual attention has been the topic of much investigation, and various theories have posited that attention is allocated either as a single unitary focus or as multiple independent foci. In the present experiment, we demonstrate that attention can be flexibly deployed as either a unitary or a divided focus in the same experimental task, depending on the observer's goals. To assess the distribution of attention, we used a dual-stream Attentional Blink (AB) paradigm and 2 target pairs. One component of the AB, Lag-1 sparing, occurs only if the second target pair appears within the focus of attention. By varying whether the first-target-pair could be expected in a predictable location (always in-stream) or not (unpredictably in-stream or between-streams), observers were encouraged to deploy a divided or a unitary focus, respectively. When the second-target-pair appeared between the streams, Lag-1 sparing occurred for the Unpredictable group (consistent with a unitary focus) but not for the Predictable group (consistent with a divided focus). Thus, diametrically different outcomes occurred for physically identical displays, depending on the expectations of the observer about where spatial attention would be required.

    Human observers show remarkable efficiency in statistical estimation; they are able, for instance, to estimate the mean size of visual objects, even if their number exceeds the capacity limits of focused attention. This ability has been understood as the result of a distinct mode of attention, i.e. distributed attention. Compared to the focused attention mode, working memory representations under distributed attention are proposed to be more compressed, leading to reduced working memory loads. An alternate proposal is that distributed attention uses less structured, feature-level representations. These would fill up working memory (WM) more, even when target set size is low. Using event-related potentials, we compared WM loading in a typical distributed attention task (mean size estimation) to that in a corresponding focused attention task (object recognition), using a measure called contralateral delay activity (CDA). Participants performed both tasks on 2, 4, or 8 different-sized target disks. In the recognition task, CDA amplitude increased with set size; notably, however, in the mean estimation task the CDA amplitude was high regardless of set size. In particular for set-size 2, the amplitude was higher in the mean estimation task than in the recognition task. The result showed that the task involves full WM loading even with a low target set size. This suggests that in the distributed attention mode, representations are not compressed, but rather less structured than under focused attention conditions. Copyright © 2012 Elsevier Ltd.

    Full Text Available Background and Study Aim: Recently, studies have shown that an external focus of attention improves the performance of individuals. Some studies have also confirmed the superiority of distances away from body for external focus of attention. The aim of this study was to determine the optimal distance of an external focus of attention when performing athletes' standing long jump. Material and Method: 51 volunteer students (M age= 23.31 ± 5.26 years were selected as sample. At first all they performed a standing long jump in control status (without instruction for focus of attention. Then in an interpersonal counterbalanced design, a pair of jumps was performed with four different distances of an external focus of attention. These distances included 0.5, 2.5, 4 and 8 meters from the jump start line marked with colored tapes on the ground. Results: The results showed that having an external focus of attention compare to the control conditions has a significant advantage in the performance of the athlete's standing long jump. Also, the performance of athletes at different distances of an external focus of attention was compared. Results showed that the four-meter distance was significantly better performance than the half-meter distance of an external focus of attention. Conclusion: Four-meter distance can be introduced as the optimal distance of an external focus of attention in the performance of athletes’ standing long jump.

    Caparos and Linnell (2009, 2010) used a variable-separation flanker paradigm to show that (a) when cognitive load is low, increasing perceptual load causes spatial attention to focus and (b) when perceptual load is high, decreasing cognitive load causes spatial attention to focus. Here, we tested whether the effects of perceptual and cognitive…

    Studies with young adults have shown that an external focus of attention (i.e., on the movement effect) results in more effective motor learning and greater automaticity than an internal focus (i.e., on one's own body movements). The present study examined whether instructions inducing an external versus internal attentional focus would differentially affect the learning of a balance task in 32 older adults (24 females and 8 males, mean age: 69.4 years), divided equally, by number and gender, into two groups. The task required participants to stand on a balance platform (stabilometer) tilting to the left and right, and to try to keep the platform as close to horizontal as possible during each 30-s trial. The external focus group was instructed to concentrate on keeping markers on the platform horizontal, while the internal focus group was instructed to concentrate on keeping their feet horizontal. The dependent variable was time in balance (i.e., platform movements within ± 5°). Participants performed 10 practice trials on day 1, with focus reminders given before each trial. Learning was assessed by a retention test, consisting of five trials without instructions, performed 1 day later. The external focus group outperformed the internal focus group in retention [F(4, 120)=3.46, p=.01]. The results demonstrate that the learning benefits of an external attentional focus are generalizable to older learners. Copyright © 2010 Elsevier B.V. All rights reserved.

    The majority of children who are born very preterm escape major impairment, yet more subtle cognitive and attention problems are very common in this population. Previous research has linked infant focused attention during exploratory play to later cognition in children born full-term and preterm. Infant focused attention can be indexed by sustained decreases in heart rate (HR). However there are no preterm studies that have jointly examined infant behavioral attention and concurrent HR response during exploratory play in relation to developing cognition. We recruited preterm infants free from neonatal conditions associated with major adverse outcomes, and further excluded infants with developmental delay (Bayley Mental Development Index [MDI attention and concurrent HR response were compared in 83 preterm infants (born 23-32 weeks gestational age [GA]) who escaped major impairment to 46 full-term infants. Focused attention and HR response were then examined in relation to Bayley MDI, after adjusting for neonatal risk. MDI did not differ by group, yet full-term infants displayed higher global focused attention ratings. Among the extremely preterm infants born attention episodes, accounted for 49% of adjusted variance in predicting concurrent MDI. There were no significant associations for later-born gestational age (29-32 weeks) or full-term infants. Among extremely preterm infants who escape major impairment, our findings suggest unique relationships between focused attention, HR deceleration, and developing cognition.

  8. The Focus of Attention is similar to other memory systems rather than uniquely different

    Full Text Available According to some current theories, the Focus of Attention, part of working memory, represents items in a privileged state that is more accessible than items stored in other memory systems. One line of evidence supporting the distinction between the focus of attention and other memory systems is the finding that items in the focus of attention are immune to proactive interference (when something learned earlier impairs the ability to remember something learned more recently. The focus of attention, then, is held to be unique: it is the only memory system that is not susceptible to proactive interference. We review the literature used to support this claim, and although there are many studies in which proactive interference was not observed, we found more studies in which it was observed. We conclude that the focus of attention is not immune to proactive interference: items in the focus of attention are susceptible to proactive interference just like items in every other memory system. And, just as in all other memory systems, it is how the items are represented and processed that plays a critical role in determining whether proactive interference will be observed.

    A recent study showed that binaural beats have an impact on the efficiency of allocating attention over time. We were interested to see whether this impact affects attentional focusing or, even further, the top-down control over irrelevant information. Healthy adults listened to gamma-frequency (40 Hz) binaural beats, which are assumed to increase attentional concentration, or a constant tone of 340 Hz (control condition) for 3 min before and during a global-local task. While the size of the congruency effect (indicating the failure to suppress task-irrelevant information) was unaffected by the binaural beats, the global-precedence effect (reflecting attentional focusing) was considerably smaller after gamma-frequency binaural beats than after the control condition. Our findings suggest that high-frequency binaural beats bias the individual attentional processing style towards a reduced spotlight of attention.

  10. Ultrasound-mediated Optical Imaging and Focusing in Scattering Media

    Suzuki, Yuta

    Because of its non-ionizing and molecular sensing nature, light has been an attractive tool in biomedicine. Scanning an optical focus allows not only high-resolution imaging but also manipulation and therapy. However, due to multiple photon scattering events, conventional optical focusing using an ordinary lens is limited to shallow depths of one transport mean free path (lt'), which corresponds to approximately 1 mm in human tissue. To overcome this limitation, ultrasonic modulation (or encoding ) of diffuse light inside scattering media has enabled us to develop both deep-tissue optical imaging and focusing techniques, namely, ultrasound-modulated optical tomography (UOT) and time-reversed ultrasonically encoded (TRUE) optical focusing. While UOT measures the power of the encoded light to obtain an image, TRUE focusing generates a time-reversed (or phase-conjugated) copy of the encoded light, using a phase-conjugate mirror to focus light inside scattering media beyond 1 lt'. However, despite extensive progress in both UOT and TRUE focusing, the low signal-to-noise ratio in encoded-light detection remains a challenge to meeting both the speed and depth requirements for in vivo applications. This dissertation describes technological advancements of both UOT and TRUE focusing, in terms of their signal detection sensitivities, operational depths, and operational speeds. The first part of this dissertation describes sensitivity improvements of encoded-light detection in UOT, achieved by using a large area (˜5 cm x 5 cm) photorefractive polymer. The photorefractive polymer allowed us to improve the detection etendue by more than 10 times that of previous detection schemes. It has enabled us to resolve absorbing objects embedded inside diffused media thicker than 80 lt', using moderate light power and short ultrasound pulses. The second part of this dissertation describes energy enhancement and fluorescent excitation using TRUE focusing in turbid media, using

    Selective attention has been known to play an important role in decision making. In the present study, we combined a cueing paradigm with a redundant-target detection task to examine how attention affects the decision process when detecting the redundant targets. Cue validity was manipulated in two experiments. The results showed that when the cue was 50 % valid in one experiment, the participants adopted a parallel self-terminating processing strategy, indicative of a diffuse attentional focus on both target locations. When the cue was 100 % valid in the second experiment, all of the participants switched to a serial self-terminating processing strategy, which in our study indicated focused attention to a single target location. This study demonstrates the flexibility of the decision mechanism and highlights the importance of top-down control in selecting a decision strategy.

  13. The focus of attention in working memory – from metaphors to mechanisms

    Directory of Open Access Journals (Sweden)

    Klaus eOberauer

    2013-10-01

    Full Text Available Many verbal theories describe working memory in terms of physical metaphors such as information flow or information containers. These metaphors are often useful but can also be misleading. This article contrasts the verbal version of the author’s three-embedded-component theory with a computational implementation of the theory. The analysis focuses on phenomena that have been attributed to the focus of attention in working memory. The verbal theory characterizes the focus of attention by a container metaphor, which gives rise to questions such as: How many items fit into the focus? The computational model explains the same phenomena mechanistically through a combination of strengthened bindings between items and their retrieval cues, and priming of these cues. The author applies the computational model to three findings that have been used to argue about how many items can be held in the focus of attention (Gilchrist & Cowan, Journal of Experimental Psychology: Learning, Memory, and Cognition, 2011; Oberauer & Bialkova, Journal of Experimental Psychology: General, 2009; Oberauer & Bialkova, Journal of Experimental Psychology: Human Perception and Performance, 2011. The modeling results imply a new interpretation of those findings: The different patterns of results across those studies don’t imply different capacity estimates for the focus of attention; they rather reflect to what extent retrieval from working memory is parallel or serial.

    Does the maintenance of feature bindings in visual short-term memory (VSTM) require sustained focused attention? This issue was investigated in three experiments, in which memory for single features (i.e., colors or shapes) was compared with memory for feature bindings (i.e., the link between the color and shape of an object). Attention was manipulated during the memory retention interval with a retro-cue, which allows attention to be directed and focused on a subset of memory items. The retro-cue was presented 700 ms after the offset of the memory display and 700 ms before the onset of the test display. If the maintenance of feature bindings - but not of individual features - in memory requires sustained focused attention, the retro-cue should not affect memory performance. Contrary to this prediction, we found that both memory for feature bindings and memory for individual features were equally improved by the retro-cue. Therefore, this finding does not support the view that the sustained focused attention is needed to properly maintain feature bindings in VSTM.

    Dual-task performance is often impaired after stroke. This may be resolved by enhancing patients’ automaticity of movement. This study sets out to test the constrained action hypothesis, which holds that automaticity of movement is enhanced by triggering an external focus (on movement effects), rather than an internal focus (on movement execution). Thirty-nine individuals with chronic, unilateral stroke performed a one-leg-stepping task with both legs in single- and dual-task conditions. Attentional focus was manipulated with instructions. Motor performance (movement speed), movement automaticity (fluency of movement), and dual-task performance (dual-task costs) were assessed. The effects of focus on movement speed, single- and dual-task movement fluency, and dual-task costs were analysed with generalized estimating equations. Results showed that, overall, single-task performance was unaffected by focus (p = .341). Regarding movement fluency, no main effects of focus were found in single- or dual-task conditions (p’s ≥ .13). However, focus by leg interactions suggested that an external focus reduced movement fluency of the paretic leg compared to an internal focus (single-task conditions: p = .068; dual-task conditions: p = .084). An external focus also tended to result in inferior dual-task performance (β = -2.38, p = .065). Finally, a near-significant interaction (β = 2.36, p = .055) suggested that dual-task performance was more constrained by patients’ attentional capacity in external focus conditions. We conclude that, compared to an internal focus, an external focus did not result in more automated movements in chronic stroke patients. Contrary to expectations, trends were found for enhanced automaticity with an internal focus. These findings might be due to patients’ strong preference to use an internal focus in daily life. Future work needs to establish the more permanent effects of learning with different attentional foci on re-automating motor

    Full Text Available Background: Great importance has been given in recent years to the impact of focus of attention cues during skills execution but not during real game play, where more cognitive skills are involved besides technical performance. Objective: The purpose of the present study was to examine the effect of internal and external focus of attention instructions on the components of the game performance (decision making, skill execution, base in tennis. Methods: The participants (N = 60 were divided into three groups and followed an intervention training program that lasted 6 weeks; IF group (n = 20 under internal focus of attention instructions, EF group (n = 20 under external focus of attention instructions and CON group (n = 20 under no attentional focus instructions. Three measurements took place (pre, post and ret in which the participants were recorded on video while playing matches in real scoring conditions.

Results: ANOVA repeated measures in a 3 (groups: IF, EF & CON × 3 (measurements: pre, post, ret revealed a significant interaction between groups and measurements and post hoc analysis indicated that the group that was instructed to focus externally improved significantly only in decision making compared to the internal focus of attention and to the control group. The score difference was maintained at the retention test as well, which indicates that the impact concerned not only performance but also learning. Conclusions: Instructions that aim to an external focus of attention enhance decision making skills, which are considered the most important element of game performance in tennis.

    To date, there are no published studies directly comparing self-controlled (SC) and externally controlled (EC) pace endurance tasks. However, previous research suggests pace control may impact on cognitive strategy use and effort perceptions. The primary aim of this study was to investigate the effects of manipulating perception of pace control on attentional focus, physiological, and psychological outcomes during running. The secondary aim was to determine the reproducibility of self-paced running performance when regulated by effort perceptions. Twenty experienced endurance runners completed four 3-km time trials on a treadmill. Subjects completed two SC pace trials, one perceived exertion clamped (PE) trial, and one EC pace time trial. PE and EC were completed in a counterbalanced order. Pacing strategy for EC and perceived exertion instructions for PE replicated the subjects' fastest SC time trial. Subjects reported a greater focus on cognitive strategies such as relaxing and optimizing running action during EC than during SC. The mean HR was 2% lower during EC than that during SC despite an identical pacing strategy. Perceived exertion did not differ between the three conditions. However, increased internal sensory monitoring coincided with elevated effort perceptions in some subjects during EC and a 10% slower completion time for PE (13.0 ± 1.6 min) than that for SC (11.8 ± 1.2 min). Altering pace control and pace regulation impacted on attentional focus. External control over pacing may facilitate performance, particularly when runners engage attentional strategies conducive to improved running efficiency. However, regulating pace based on effort perceptions alone may result in excessive monitoring of bodily sensations and a slower running speed. Accordingly, attentional focus interventions may prove beneficial for some athletes to adopt task-appropriate attentional strategies to optimize performance.

    Maintaining an external direction of focus during practice is reported to facilitate acquisition of non-speech motor skills, but it is not known whether these findings also apply to treatment for speech errors. This question has particular relevance for treatment incorporating visual biofeedback, where clinician cueing can direct the learner's attention either internally (i.e., to the movements of the articulators) or externally (i.e., to the visual biofeedback display). This study addressed two objectives. First, it aimed to use single-subject experimental methods to collect additional evidence regarding the efficacy of visual-acoustic biofeedback treatment for children with /r/ misarticulation. Second, it compared the efficacy of this biofeedback intervention under two cueing conditions. In the external focus (EF) condition, participants' attention was directed exclusively to the external biofeedback display. In the internal focus (IF) condition, participants viewed a biofeedback display, but they also received articulatory cues encouraging an internal direction of attentional focus. Nine school-aged children were pseudo-randomly assigned to receive either IF or EF cues during 8 weeks of visual-acoustic biofeedback intervention. Accuracy in /r/ production at the word level was probed in three to five pre-treatment baseline sessions and in three post-treatment maintenance sessions. Outcomes were assessed using visual inspection and calculation of effect sizes for individual treatment trajectories. In addition, a mixed logistic model was used to examine across-subjects effects including phase (pre/post-treatment), /r/ variant (treated/untreated), and focus cue condition (internal/external). Six out of nine participants showed sustained improvement on at least one treated /r/ variant; these six participants were evenly divided across EF and IF treatment groups. Regression results indicated that /r/ productions were significantly more likely to be rated accurate post

    Preferentially processing behaviorally relevant information is vital for primate survival. In visuospatial attention studies, manipulating the spatial extent of attention focus is an important question. Although many studies have claimed to successfully adjust attention field size by either varying the uncertainty about the target location (spatial uncertainty) or adjusting the size of the cue orienting the attention focus, no systematic studies have assessed and compared the effectiveness of these methods. We used a multiple cue paradigm with 2.5° and 7.5° rings centered around a target position to measure the cue size effect, while the spatial uncertainty levels were manipulated by changing the number of cueing positions. We found that spatial uncertainty had a significant impact on reaction time during target detection, while the cue size effect was less robust. We also carefully varied the spatial scope of potential target locations within a small or large region and found that this amount of variation in spatial uncertainty can also significantly influence target detection speed. Our results indicate that adjusting spatial uncertainty is more effective than varying cue size when manipulating attention field size.

    Self-focusing effects are of central importance for most nonlinear optical effects. The critical power for self-focusing is commonly investigated theoretically without considering a material’s absorption. Although this is practicable for various materials, investigating the critical power for self-focusing in media with non-negligible absorption is also necessary, because this is the situation usually met in practice. In this paper, the simple analytical expressions describing the relationships among incident power, absorption coefficient and focal position are provided by a simple physical model based on the Fermat principle. Expressions for the absorption dependent critical power are also derived; these can play important roles in experimental and applied research on self-focusing-related nonlinear optical phenomena in absorbing media. Numerical results, based on the nonlinear wave equation—and which can predict experimental results perfectly—are also presented, and agree quantitatively with the analytical results proposed in this paper.

    Meditation refers to a family of complex emotional and attentional regulatory practices, which can be classified into two main styles - focused attention (FA) and open monitoring (OM) - involving different attentional, cognitive monitoring and awareness processes. In a functional magnetic resonance study we originally characterized and contrasted FA and OM meditation forms within the same experiment, by an integrated FA-OM design. Theravada Buddhist monks, expert in both FA and OM meditation forms, and lay novices with 10 days of meditation practice, participated in the experiment. Our evidence suggests that expert meditators control cognitive engagement in conscious processing of sensory-related, thought and emotion contents, by massive self-regulation of fronto-parietal and insular areas in the left hemisphere, in a meditation state-dependent fashion. We also found that anterior cingulate and dorsolateral prefrontal cortices play antagonist roles in the executive control of the attention setting in meditation tasks. Our findings resolve the controversy between the hypothesis that meditative states are associated to transient hypofrontality or deactivation of executive brain areas, and evidence about the activation of executive brain areas in meditation. Finally, our study suggests that a functional reorganization of brain activity patterns for focused attention and cognitive monitoring takes place with mental practice, and that meditation-related neuroplasticity is crucially associated to a functional reorganization of activity patterns in prefrontal cortex and in the insula.

    2017-05-01

    Impaired performance while executing a motor task is attributed to a disruption of normal automatic processes when an internal focus of attention is used. What remains unclear is whether the specificity of internally focused task instructions may impact task performance. The present study assessed the implications of changing the attentional focus of novice and skilled golfers by measuring behavioural, neurophysiological and kinematic changes during a golf putting task. Over six blocks of ten putting trials each, attention was directed either externally (towards the target) or internally in one of two ways: 1) proximal (keeping the elbows extended and the hands gripping the putter); or 2) distal (keeping the weight evenly distributed between both legs) to the critical elements of the task. Results provided evidence that when novice participants use an internal focus of attention more closely associated with task performance that their: 1) execution; 2) accuracy; 3) variability of surface electromyography (sEMG) activity; and 4) kinematics of the putter movement are all adversely affected. Skilled golfers are much more resilient to changes in attentional focus, while all participants interpret a distal internal focus of attention similar to an external focus. All participants produced decreased activity in the muscle (tibialis anterior) associated with the distal (less task relevant) focus of attention even when the "internal" focus was on the lower extremity. Our results provide evidence that the skill level of the participant and the distance of the internal focus of attention from the key elements of a motor skill directly impact the execution, muscle activity, and movement kinematics associated with skilled motor task performance.

    Full Text Available In two experiments we investigated the automatic adjusting of the attentional focus to simple geometric shapes. The participants performed a visual search task with four stimuli (the target and three distractors presented always around the fixation point, inside an outlined frame not related to the search task. A cue informed the subject only about the possible size and shape of the frame, not about the target. The results of the first experiment showed faster target detection in the valid cue trials, suggesting that attention was captured automatically by the cue shape. In the second experiment, we introduced a flanker stimulus (compatible or incompatible with the target in order to determine if attentional resources spread homogenously inside and outside the frame. The results showed that performance depended both on cue validity and frame orientation. The flanker effect was dependent on compatibility and flanker position (vertical or horizontal meridian. The results of both experiments suggest that the form of an irrelevant object can capture attention despite participants’ intention and the results of the second experiment suggest that the attentional resources are more concentrated along the horizontal meridian.

    This study evaluated the influence of different attentional foci for varied grip widths in the bench press. Eighteen resistance-trained men were familiarized with the procedure and performed a one-repetition maximum (1RM) test during Session 1. In Session 2, they used three different standardized grip widths (100%, 150%, and 200% of biacromial width distance) in random order at 50% of 1RM while also engaged in three different attention focus conditions (external focus on the bench press, internal focus on pectoralis major muscles, and internal focus on triceps brachii muscles). Surface electromyography (EMG) signals were recorded from the triceps brachii and pectoralis major, and peak EMG of the filtered signals were normalized to maximum EMG of each muscle. Both grip width and focus influenced the muscle activity level, but there were no significant interactions between these variables. Exploratory analyses suggested that an internal focus may slightly (4%-6%) increase pectoralis major activity at wider grip widths and triceps brachii activity at narrower grip widths, but this should be confirmed or rejected in a study with a larger sample size or through a meta-analysis of research to date.

    Full Text Available We consider the role of physical form, prior experience, and form focused instruction (FFI in adult language learning. (1 When presented with competing cues to interpretation, learners are more likely to attend to physically more salient cues in the input. (2 Learned attention is an associative learning phenomenon where prior-learned cues block those that are experienced later. (3 The low salience of morphosyntactic cues can be overcome by FFI, which leads learners to attend cues which might otherwise be ignored. Experiment 1 used eye-tracking to investigate how language background influences learners’ attention to morphological cues, as well as the attentional processes whereby different types of FFI overcome low cue salience, learned attention and blocking. Chinese native speakers (no L1 verb-tense morphology viewed Latin utterances combining lexical and morphological cues to temporality under control conditions (CC and three types of explicit FFI: grammar instruction (VG, verb salience with textual enhancement (VS, and verb pretraining (VP, and their use of these cues was assessed in a comprehension test. CC participants were significantly more sensitive to the adverbs than verb morphology. Instructed participants showed greater sensitivity to the verbs. These results reveal attentional processes whereby learners’ prior linguistic experience can shape their attention toward cues in the input, and whereby FFI helps learners overcome the long-term blocking of verb-tense morphology. Experiment 2 examined the role of modality of input presentation – aural or visual – in L1 English learners’ attentional focus on morphological cues and the effectiveness of different FFI manipulations. CC participants showed greater sensitivity toward the adverb cue. FFI was effective in increasing attention to verb-tense morphology, however, the processing of morphological cues was considerably more difficult under aural presentation. From visual exposure

    The present paper discusses attentional focus in motor learning and performance from the point of view of mindful movement practices, taking as a starting point the Feldenkrais method. It is argued that earlier criticism of the Feldenkrais method (and thereby implicitly of mindful movement practices more generally) because of allegedly inappropriate attentional focus turns out to be unfounded in light of recent developments in the study of motor learning and performance. Conversely, the examples of the Feldenkrais method and Ki-Aikido are used to illustrate how both Western and Eastern (martial arts derived) mindful movement practices might benefit sports psychology. © The Author(s) 2016.

    Paying attention to thin media models may negatively affect women's self-evaluation. This study aimed to reduce the amount of attention that young women give to appearance-related information by challenging the sociocultural norms for appearance, and studied the moderating role of self-esteem. Seventy-one college women either received norm-confirming, norm-challenging, or no information regarding the sociocultural norms for appearance. Subsequently, participants' visual attention to appearance-related and neutral advertisements was measured using an eye-tracker. The results demonstrate that when no information or norm-confirming information was received, women with lower self-esteem paid more attention to the appearance-related advertisements than women with higher self-esteem. Importantly however, when norm-challenging information was received, women with lower self-esteem paid significantly less attention to the appearance-related ads than women with lower self-esteem who did not receive this manipulation. These findings indicate that challenging the sociocultural norms for appearance can attenuate the amount of attention women give to appearance-related media. Copyright © 2013 Elsevier Ltd.

    2017-09-01

    This study investigated the temporal stability and correlates of attention-related body sensations that emerge without external stimulation during rest and due to focused attention on a body part. To assess attention-related body sensations, participants were asked to focus on a freely chosen body area with closed eyes, and had to report whether the sensation of that area had changed. Self-report questionnaires were used to assess various aspects of body focus (body awareness, body responsiveness, somatosensory amplification, subjective somatic symptoms), and positive and negative affectivity. Previous experiences in body-mind therapies were also measured. PEBL Continuous Performance Test was used to assess sustained attention. Heart rate variability scores were based on a 3-minute long resting heart rate measurement. Fifty-eight university students (22.3 ± 3.95 years; 34 females) participated in the study. The stability of attention-related body sensations was measured 8 weeks later on a randomly chosen sub-group (n = 28). Attention-related body sensations showed a mediocre temporal stability (r ρ  = 0.47, p = 0.012). People reporting attention-related body sensations showed significantly higher body awareness, somatosensory amplification, and resting heart rate; and marginally higher somatic symptoms. No relation was found with body-mind practice, body responsiveness, positive and negative affect, the vagal component of heart rate variability, and performance in the sustained attention task. Attention-related sensations are relatively stable over time. They are connected to some, but not to all of the aspects of body focus. Further studies are needed to elaborate the influencing stable and situational factors.

    Full Text Available For making decisions in everyday life we often have first to infer the set of environmental features that are relevant for the current task. Here we investigated the computational mechanisms underlying the evolution of beliefs about the relevance of environmental features in a dynamical and noisy environment. For this purpose we designed a probabilistic Wisconsin card sorting task (WCST with belief solicitation, in which subjects were presented with stimuli composed of multiple visual features. At each moment in time a particular feature was relevant for obtaining reward, and participants had to infer which feature was relevant and report their beliefs accordingly. To test the hypothesis that attentional focus modulates the belief update process, we derived and fitted several probabilistic and non-probabilistic behavioral models, which either incorporate a dynamical model of attentional focus, in the form of a hierarchical winner-take-all neuronal network, or a diffusive model, without attention-like features. We used Bayesian model selection to identify the most likely generative model of subjects' behavior and found that attention-like features in the behavioral model are essential for explaining subjects' responses. Furthermore, we demonstrate a method for integrating both connectionist and Bayesian models of decision making within a single framework that allowed us to infer hidden belief processes of human subjects.

  14. Dual n-back training increases the capacity of the focus of attention.

    2013-02-01

    Working memory (WM) training has been reported to benefit abilities as diverse as fluid intelligence (Jaeggi et al., Proceedings of the National Academy of Sciences of the United States of America, 105:6829-6833, 2008) and reading comprehension (Chein & Morrison, Psychonomic Bulletin & Review, 17:193-199, 2010), but transfer is not always observed (for reviews, see Morrison & Chein, Psychonomics Bulletin & Review, 18:46-60, 2011; Shipstead et al., Psychological Bulletin, 138:628-654, 2012). In contrast, recent WM training studies have consistently reported improvement on the trained tasks. The basis for these training benefits has received little attention, however, and it is not known which WM components and/or processes are being improved. Therefore, the goal of the present study was to investigate five possible mechanisms underlying the effects of adaptive dual n-back training on working memory (i.e., improvements in executive attention, updating, and focus switching, as well as increases in the capacity of the focus of attention and short-term memory). In addition to a no-contact control group, the present study also included an active control group whose members received nonadaptive training on the same task. All three groups showed significant improvements on the n-back task from pretest to posttest, but adaptive training produced larger improvements than did nonadaptive training, which in turn produced larger improvements than simply retesting. Adaptive, but not nonadaptive, training also resulted in improvements on an untrained running span task that measured the capacity of the focus of attention. No other differential improvements were observed, suggesting that increases in the capacity of the focus of attention underlie the benefits of adaptive dual n-back training.

    This study investigated the influence of music on the rating of perceived exertion (RPE) and attentional focus during walking at a self-selected pace. Fifteen overweight and obese women volunteered to participate in the study. They underwent four sessions: the first for incremental maximal test and anthropometric measurement followed by three experimental sessions. After the first session, they were exposed to three 30-minute walking sessions at a self-selected pace in a counterbalanced order: fast-tempo music (FT), medium-tempo music (MT) and no-music control (NM). Borg's RPE Scale and an Attentional Focus Questionnaire were used to measure the perceptual response and attentional focus, respectively. Results showed that the RPE was higher in the no-music control than in the medium-tempo music (12.05 ± 0.6 vs. 10.5 ± 0.5). Furthermore, dissociative attentional focus was greater for both conditions with music in comparison with the no-music control (NM= 39.0 ± 4.1; MT= 48.4 ± 4.1 and FT= 47.9 ± 4.5). The results indicated that the use of music during walking can modulate attentional focus, increasing dissociative thought, and medium-tempo music can reduce the RPE.

    2017-09-01

    Conclusions: HIA media portrayals warrant further inquiry from researchers and practitioners. Focusing on how media portrays HIAs is consistent with several HIA steps. It is also important for a broader strategy to educate stakeholders about HIAs and to understand HIAs’ utility. HIA practitioners should develop and implement guidelines for media interaction and tracking that encourage practitioners to seek additional media attention and to focus such attention on health impacts and outcomes, HIA recommendations, and HIA values. Building on our work, researchers should examine HIA media portrayals beyond the context of this study.

    A recent study showed that binaural beats have an impact on the efficiency of allocating attention over time. We were interested to see whether this impact affects attentional focusing or, even further, the top-down control over irrelevant information. Healthy adults listened to gamma-frequency (40?Hz) binaural beats, which are assumed to increase attentional concentration, or a constant tone of 340?Hz (control condition) for 3?min before and during a global?local task. While the size of the ...

Im Projekt Globale Mediengenerationen (GMG wurden Medienerinnerungen aus der Kindheit im Kontext von Gruppendiskussionen am Beispiel dreier Generationen aus verschiedenen Ländern aller Kontinente untersucht. Dabei wurden medienbezogene Wissensbestände von drei Alterskohorten globaler Generationen analysiert. Der Artikel diskutiert methodologische Aspekte des Projekts und komplexe und selektive Prozesse des Erinnerns vergangener Ereignisse. Er untersucht Gemeinsamkeiten und Unterschiede des GMG-Ansatzes mit dem dokumentarischen Ansatz von Ralf Bohnsack, die beide in der Wissenssoziologie von Karl Mannheim verwurzelt sind. Darüber hinaus wird Medialität als basale methodologische Kategorie in Erwägung gezogen, nicht nur im Hinblick auf die Klärung begrifflicher Grundlagen, sondern auch als inhärente Dimension von Forschungsprozessen. Media events in general and the introduction and divulgence of new media technologies and formats in particular implicate various (new ways of “media entering life.” In the Global Media Generations (GMG research project, articulation of individuals’ memories of childhood experiences with the media was afforded by context of focus groups of three generations in different countries of six continents. In this project media related knowledge segments of different age cohorts have been analyzed and interpreted. The article deals with methodological questions of the project and complex processes of ‘remembering’ past events. It explores commonalities and differences of the GMG approach with Ralf Bohnsack’s documentary approach, both rooted in the sociology of knowledge of Karl Mannheim.

    Four experiments were conducted to study the effect of self-focused attention on affective reactions. In addition, the research was also intended to help resolve the controversy over attentional versus arousal explanations of self-awareness research. In Experiment 1, undergraduate men were asked to view and rate slides of nude women in the presence of a mirror or with no mirror. In Experiment 3, subjects were either exposed or not exposed to a mirror and read a set of mood statements which became either increasingly positive or increasingly negative. Experiments 2 and 4 conceptually replicated Experiments 1 and 3 by selecting subjects on the basis of private self-consciousness. In each study, self-focused attention increased the person's responsiveness to his transient affective state. The convergence between mirror-manipulated self-awareness and private self-consciousness was offered as support for an attentional interpretation of the findings. The implications of the research for self-awareness theory are discussed.

    2012-12-01

    Research has identified a relation between exposure to thin-ideal magazine and television media images and eating disorder pathology. However, few studies have examined the potential influence of Internet media on eating disorder behaviors and attitudes. This study investigated associations among image-focused media exposure, body dissatisfaction, eating pathology and thin-ideal internalization in a sample of 421 female undergraduates. Undergraduate women spent significantly more time viewing online appearance-oriented media, rather than reading image-focused magazines. Appearance-oriented Internet and television use were associated with eating pathology. Moreover, the association between image-focused Internet use and BD was mediated by thin-ideal internalization. These findings are consistent with those of previous research, and highlight the vulnerability individuals high in thin-ideal internalization might have to media exposure. They also suggest that Internet media use is an important topic to attend to in eating disorders prevention and treatment. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Judah, Matt R; Grant, DeMond M; Carlisle, Nancy B

    2016-06-01

    Cognitive theories of social anxiety disorder suggest that biased attention plays a key role in maintaining symptoms. These biases include self-focus and attention to socially threatening stimuli in the environment. The goal of this study was to utilize ERPs that are elicited by a change detection task to examine biases in selective attention (i.e., N2pc) and working memory maintenance (i.e., contralateral delay activity; CDA). Additionally, the effect of self-focus was examined using false heart rate feedback. In support of the manipulation, self-focus cues resulted in greater self-reported self-consciousness and task interference, enhanced anterior P2 amplitude and reduced SPN amplitude. Moreover, P2 amplitude for self-focus cues was correlated with reduced task performance for socially anxious subjects only. The difference in P2 amplitude between self-focus and standard cues was correlated with social anxiety independent of depression. As hypothesized, socially anxious participants (n = 20) showed early selection and maintenance of disgust faces relative to neutral faces as indicated by the N2pc and CDA components. Nonanxious controls (n = 22) did not show these biases. During self-focus cues, controls showed marginal evidence of biased selection for disgust faces, whereas socially anxious subjects showed no bias in this condition. Controls showed an ipsilateral delay activity after being cued to attend to one hemifield. Overall, this study supports early and persistent attentional bias for social threat in socially anxious individuals. Furthermore, self-focus may disrupt these biases. These findings and supplementary data are discussed in light of cognitive models of social anxiety disorder, recent empirical findings, and treatment.

    2016-01-01

    The authors investigated the relative effectiveness of different attentional focus instructions on motor learning in primary school children. In addition, we explored whether the effect of attentional focus on motor learning was influenced by children's age and verbal working memory capacity. Novice 8-9-year old children (n = 30) and 11-12-year-old children (n = 30) practiced a golf putting task. For each age group, half the participants received instructions to focus (internally) on the swing of their arm, while the other half was instructed to focus (externally) on the swing of the club. Children's verbal working memory capacity was assessed with the Automated Working Memory Assessment. Consistent with many reports on adult's motor learning, children in the external groups demonstrated greater improvements in putting accuracy than children who practiced with an internal focus. This effect was similar across age groups. Verbal working memory capacity was not found to be predictive of motor learning, neither for children in the internal focus groups nor for children in the external focus groups. In conclusion, primary school children's motor learning is enhanced by external focus instructions compared to internal focus instructions. The purported modulatory roles of children's working memory, attentional capacity, or focus preferences require further investigation.

    Impairments in attention following traumatic brain injury (TBI) can significantly impact recovery and rehabilitation effectiveness. This study investigated the multi-faceted construct of selective attention following TBI, highlighting the differences on visual nonsearch (focused attention) and search (divided attention) tasks. Participants were 30 individuals with moderate to severe TBI who were tested acutely (i.e. following emergence from PTA) and 30 age- and education-matched controls. Participants were presented with visual displays that contained either two or eight items. In the focused attention, nonsearch condition, the location of the target (if present) was cued with a peripheral arrow prior to presentation of the visual displays. In the divided attention, search condition, no spatial cue was provided prior to presentation of the visual displays. The results revealed intact focused, nonsearch, attention abilities in the acute phase of TBI recovery. In contrast, when no spatial cue was provided (divided attention condition), participants with TBI demonstrated slower visual search compared to the control group. The results of this study suggest that capitalizing on intact focused attention abilities by allocating attention during cognitively demanding tasks may help to reduce mental workload and improve rehabilitation effectiveness.

    Sarah is a 13-year-old eighth grader who was recently diagnosed for the first time with attention-deficit/hyperactivity disorder (ADHD)-inattentive type, and the family elected to treat her with behavioral interventions to help her organization and attention. She had struggled with distractibility and disorganization since the fourth grade. At home, Sarah's mother described her as "spacey" and unable to complete the morning routine without constant supervision. Over time, her mother observed that it seemed as if Sarah had given up on school.As Sarah became an adolescent, her self-esteem suffered because of her academic struggles, and she placed increasing emphasis on her appearance, including focus on remaining thin and refusing to leave the house without makeup. It was in this context that Sarah recently posted photographs of herself in various stages of undress and/or drinking alcohol on Snapchat, a photograph-sharing application in which users can send "snaps"-photographs that disappear soon after opening. However, snap recipients can take a screenshot or photograph of the snap, thereby saving the image. For unknown reasons, Sarah's close female friend took screenshots of these provocative photographs and sent them to their classmates and Sarah's older brother.Sarah's family contacted the police and has been working with her school to address this incident. This experience resulted in significant family stress and distrust of Sarah.

    Performance in working memory (WM) tasks depends on the capacity for storing objects and on the allocation of attention to these objects. Here, we explored how capacity models need to be augmented to account for the benefit of focusing attention on the target of recall. Participants encoded six colored disks (Experiment 1) or a set of one to eight colored disks (Experiment 2) and were cued to recall the color of a target on a color wheel. In the no-delay condition, the recall-cue was presented after a 1,000-ms retention interval, and participants could report the retrieved color immediately. In the delay condition, the recall-cue was presented at the same time as in the no-delay condition, but the opportunity to report the color was delayed. During this delay, participants could focus attention exclusively on the target. Responses deviated less from the target's color in the delay than in the no-delay condition. Mixture modeling assigned this benefit to a reduction in guessing (Experiments 1 and 2) and transposition errors (Experiment 2). We tested several computational models implementing flexible or discrete capacity allocation, aiming to explain both the effect of set size, reflecting the limited capacity of WM, and the effect of delay, reflecting the role of attention to WM representations. Both models fit the data better when a spatially graded source of transposition error is added to its assumptions. The benefits of focusing attention could be explained by allocating to this object a higher proportion of the capacity to represent color.

  15. Third-harmonic generation in isotropic media by focused pulses

    For focused pulses of light in isotropic nonlinear media, third-harmonic generation can be strongly affected by group-velocity mismatch between the fundamental and third-harmonic. There is a characteristic time determined by the group-velocity mismatch and the Rayleigh range of the focused pulse. The dynamics depend on two dimensionless quantities, namely the ratio of the characteristic time to the pulse duration and the phase-velocity mismatch times the Rayleigh range. Pulses shorter than the characteristic time have physics described by simple analytic formulas. Pulses near the characteristic time have an intermediate behavior given by an explicit but more complicated formula. Pulses longer than the characteristic time tend to the continuous-wave case

    Selective auditory attention causes a relative enhancement of the neural representation of important information and suppression of the neural representation of distracting sound, which enables a listener to analyze and interpret information of interest. Some studies suggest that in both vision and in audition, the "unit" on which attention operates is an object: an estimate of the information coming from a particular external source out in the world. In this view, which object ends up in the attentional foreground depends on the interplay of top-down, volitional attention and stimulus-driven, involuntary attention. Here, we test the idea that auditory attention is object based by exploring whether continuity of a non-spatial feature (talker identity, a feature that helps acoustic elements bind into one perceptual object) also influences selective attention performance. In Experiment 1, we show that perceptual continuity of target talker voice helps listeners report a sequence of spoken target digits embedded in competing reversed digits spoken by different talkers. In Experiment 2, we provide evidence that this benefit of voice continuity is obligatory and automatic, as if voice continuity biases listeners by making it easier to focus on a subsequent target digit when it is perceptually linked to what was already in the attentional foreground. Our results support the idea that feature continuity enhances streaming automatically, thereby influencing the dynamic processes that allow listeners to successfully attend to objects through time in the cacophony that assails our ears in many everyday settings.

  18. Focused attention, open monitoring and automatic self-transcending: Categories to organize meditations from Vedic, Buddhist and Chinese traditions.

    2010-12-01

    This paper proposes a third meditation-category--automatic self-transcending--to extend the dichotomy of focused attention and open monitoring proposed by Lutz. Automatic self-transcending includes techniques designed to transcend their own activity. This contrasts with focused attention, which keeps attention focused on an object; and open monitoring, which keeps attention involved in the monitoring process. Each category was assigned EEG bands, based on reported brain patterns during mental tasks, and meditations were categorized based on their reported EEG. Focused attention, characterized by beta/gamma activity, included meditations from Tibetan Buddhist, Buddhist, and Chinese traditions. Open monitoring, characterized by theta activity, included meditations from Buddhist, Chinese, and Vedic traditions. Automatic self-transcending, characterized by alpha1 activity, included meditations from Vedic and Chinese traditions. Between categories, the included meditations differed in focus, subject/object relation, and procedures. These findings shed light on the common mistake of averaging meditations together to determine mechanisms or clinical effects. Copyright © 2010 Elsevier Inc. All rights reserved.

    Full Text Available Objective: The aim of this study was to evaluate the impact of the external focus of attention on the rotator cuff muscle activity for the timely hit forehand drive by table tennis players. Methods: Twelve professional table tennis players with mean age of 26.5 years voluntarily participated in this study. The electrical activities of the muscles of the shoulder girdle using M.A 300 machine and bipolar electrodes surface under two conditions .First with external focus of attention and then without such attention were recorded, first without any guidance blows forehand drive was carried out by subjects (without focus. Then such subject was asked to focus their attention on the area marked for the ball landing (external focus of attention.      Muscle activities in both preparation and tapping phases were analyzed the three –dimensional (200 Hz, Vicon, with four camera series T motion analysis system was used to obtain the data. Data was analyzed by running reported measures ANOVA at a significance level of p0.05 but the different between the intensity of muscle activity was meaningful. This suggests that there is a mutual influence between the two attention factors and muscles (p=0.03, that is, orientation can have a significant effect on the severity of muscle contraction. Intensities of muscle contraction in the preparation and tapping were different (p<0.05. Conclusion: On the forehand drive technique, the anterior deltoid muscle has the most activity. The type of focus and attention had a significant impact on the change of activity of muscles relative to each other, and the greatest impact is on the reduction of activity of the infraspinatus muscle. This type of focus delays fatigue and results in an increase in the efficiency of neuromuscular in the activities of skills.

J Strength Cond Res 32(2): 514-519, 2018-Few studies have examined the role of the teleoanticipation during resistance training. The purpose of this study was to examine the effect of bench press (BP) load knowledge on repetitions completed, ratings of perceived exertion (RPEs), and attentional focus (% associative). Thirty-six recreationally active resistance-trained men (n = 25) and women (n = 11) participated in this study (age = 20.97 ± 1.87 years; ht = 174.12 ± 9.41 cm; and mass = 80.14 ± 14.03 kg). All subjects completed 3 testing sessions: (a) 1 repetition maximum (1RM) BP determination; (b) submaximal BP repetitions to fatigue known load (KL); and (c) submaximal BP repetitions to fatigue unknown load (UL). Known load and UL sessions were randomized and counterbalanced and both completed at 70% 1RM. An estimated weight ratio was computed using the subject's estimate of the UL weight relative to the KL weight. An independent samples t-test revealed no significant testing order difference for the estimated weight ratio. Two-way repeated-measures analysis of variances revealed no significant differences in the number of repetitions (p = 0.63), RPE (p = 0.18), or attentional focus (% associative) (p = 0.93) between the KL and UL conditions. Pearson correlations found a moderate positive association between KL repetitions completed and % associative focus when the UL was completed before the KL. Load knowledge did not influence the number of repetitions, RPE, or attentional focus while completing the BP. Further research examining the use of pacing strategies, RPE, and attentional focus during KL and UL conditions are warranted.

  1. Object selection costs in visual working memory: A diffusion model analysis of the focus of attention.

    2016-11-01

    A central question in working memory research concerns the degree to which information in working memory is accessible to other cognitive processes (e.g., decision-making). Theories assuming that the focus of attention can only store a single object at a time require the focus to orient to a target representation before further processing can occur. The need to orient the focus of attention implies that single-object accounts typically predict response time costs associated with object selection even when working memory is not full (i.e., memory load is less than 4 items). For other theories that assume storage of multiple items in the focus of attention, predictions depend on specific assumptions about the way resources are allocated among items held in the focus, and how this affects the time course of retrieval of items from the focus. These broad theoretical accounts have been difficult to distinguish because conventional analyses fail to separate components of empirical response times related to decision-making from components related to selection and retrieval processes associated with accessing information in working memory. To better distinguish these response time components from one another, we analyze data from a probed visual working memory task using extensions of the diffusion decision model. Analysis of model parameters revealed that increases in memory load resulted in (a) reductions in the quality of the underlying stimulus representations in a manner consistent with a sample size model of visual working memory capacity and (b) systematic increases in the time needed to selectively access a probed representation in memory. The results are consistent with single-object theories of the focus of attention. The results are also consistent with a subset of theories that assume a multiobject focus of attention in which resource allocation diminishes both the quality and accessibility of the underlying representations.

    Over-consuming unhealthful foods and beverages contributes to pediatric obesity and associated diseases. Food marketing influences children's food preferences, choices, and intake. To examine whether adding licensed media characters to healthful food/beverage packages increases children's attention to and preference for these products. We hypothesized that children prefer less- (vs more-) healthful foods, and pay greater attention to and preferentially select products with (vs without) media characters regardless of nutritional quality. We also hypothesized that children prefer more-healthful products when characters are present over less-healthful products without characters. On a computer, participants viewed food/beverage pairs of more-healthful and less-healthful versions of similar products. The same products were shown with and without licensed characters on the packaging. An eye-tracking camera monitored participant gaze, and participants chose which product they preferred from each of 60 pairs. Six- to 9-year-old children (n=149; mean age=7.36, standard deviation=1.12) recruited from the Twin Cities, MN, area in 2012-2013. Visual attention and product choice. Attention to products was compared using paired-samples t tests, and product choice was analyzed with single-sample t tests. Analyses of variance were conducted to test for interaction effects of specific characters and child sex and age. Children paid more attention to products with characters and preferred less-healthful products. Contrary to our prediction, children chose products without characters approximately 62% of the time. Children's choices significantly differed based on age, sex, and the specific cartoon character displayed, with characters in this study being preferred by younger boys. Results suggest that putting licensed media characters on more-healthful food/beverage products might not encourage all children to make healthier food choices, but could increase selection of healthy foods

    Rehabilitation for patients with Parkinson's disease (PD) is based on cognitive strategies that exploit attention. Parkinsonians exhibit impairments in divided attention and interference control. Nevertheless, the effectiveness of specific rehabilitation treatments based on attention suggests that other attentional functions are preserved. Data about attention are conflicting in PD, and it is not clear whether rehabilitative treatments that entail attentional strategies affect attention itself. Reaction times (RTs) represent an instrument to explore attention and investigate whether changes in attentional performances parallel rehabilitation induced-gains. RTs of 103 parkinsonian patients in "on" state, without cognitive deficits, were compared with those of a population of 34 healthy controls. We studied those attentional networks that subtend the use of cognitive strategies in motor rehabilitation: alertness and focused and sustained attention, which is a component of the executive system. We used visual and auditory RTs to evaluate alertness and multiple choices RTs (MC RTs) to explore focused and sustained attention. Parkinsonian patients underwent these tasks before and after a 4-week multidisciplinary, intensive and goal-based rehabilitation treatment (MIRT). Unified Parkinson's Disease Rating Scale (UPDRS) III and Timed Up and Go test (TUG) were assessed at the enrollment and at the end of MIRT to evaluate the motor-functional effectiveness of treatment. We did not find differences in RTs between parkinsonian patients and controls. Further, we found that improvements in motor-functional outcome measures after MIRT ( p attention, are preserved in "on" state. This explains why Parkinsonians benefit from a goal-based rehabilitation that entails the use of attention. The reduction in MC RTs suggests a positive effect of MIRT on the executive component of attention and indicates that this type of rehabilitation provides benefits by exploiting executive functions

  8. Understanding mental distress in film and media: a new agenda?

    Science.gov (United States)

    Harper, Stephen

    2008-07-01

    This paper surveys some recent developments in media criticism and recent developments in film and media representations of mental distress. Focusing on a representations drawn from various forms of media, the paper argues that media and film images of mental distress are in many cases 'positive' and sympathetic, although they can also contain sexist, racist and other problematic elements that are not commonly identified by anti-stigma campaigners. It also suggests that while still valid in many ways, existing anti-stigma criticism tends to focus on a rather undifferentiated notion of 'violence to others' as the sole criterion against which media images are judged. Finally, the paper proposes that critics and campaigners pay closer attention to how the particular form or genre of any media text influences its treatment of psychological distress.

  9. Swiftly moving focus points and forming shapes through the scattering media

    Propagation of light through scattering media such as ground glass or biological tissue limits the quality and intensity of focusing point. Wave front shaping technique which uses spatial light modulator (SLM) devices to reshape the field profile of incoming light, is considered as one of the most effective and convenient methods. Advanced biomedical or manufacturing applications require drawing various contours or shapes quickly and precisely. However, creating each shape behind the scattering medium needs different phase profiles, which are time consuming to optimize or measure. Here, we demonstrate a technique to draw various shapes or contours behind the scattering medium by swiftly moving the focus point without any mechanical movements. Our technique relies on the existence of speckle correlation property in scattering media, also known as optical memory effect. In our procedure, we first modulate the phase-only SLM to create the focus point on the other side of scattering medium. Then, we digitally shift the preoptimized phase profile on the SLM and ramp it to tilt the beam accordingly. Now, the incoming beam with identical phase profile shines on the same scattering region at a tilted angle to regenerate the focus point at the desired position due to memory effect. Moreover, with linear combination of different field patterns, we can generate a single phase profile on SLM to produce two, three or more focus points simultaneously on the other side of a turbid medium. Our method could provide a useful tool for prominent applications such as opto-genetic excitation, minimally invasive laser surgery and other related fields.

    It is widely assumed that the short-term retention of information is accomplished via maintenance of an active neural trace. However, we demonstrate that memory can be preserved across a brief delay despite the apparent loss of sustained representations. Delay-period activity may in fact reflect the focus of attention, rather than short-term memory. We unconfounded attention and memory by causing external and internal shifts of attention away from items that were being actively retained. Mult...

    Nafati, Gilel; Vuillerme, Nicolas

    2011-12-01

    This experiment was designed to investigate whether and how decreasing the amount of attentional focus invested in postural control could affect bipedal postural control. Twelve participants were asked to stand upright as immobile as possible on a force platform in one control condition and one cognitive condition. In the latter condition, they performed a short-term digit-span memory task. Decreased center-of-gravity displacements and decreased center-of-foot-pressure displacements minus center-of-gravity displacements were observed in the cognitive condition relative to the control condition. These results suggest that shifting the attentional focus away from postural control by executing a concurrent attention-demanding task could increase postural performance and postural efficiency.

  12. Focusing on media body ideal images triggers food intake among restrained eaters: a test of restraint theory and the elaboration likelihood model.

    2014-04-01

    Although research consistently shows that images of thin women in the media (media body ideals) affect women negatively (e.g., increased weight dissatisfaction and food intake), this effect is less clear among restrained eaters. The majority of experiments demonstrate that restrained eaters - identified with the Restraint Scale - consume more food than do other participants after viewing media body ideal images; whereas a minority of experiments suggest that such images trigger restrained eaters' dietary restraint. Weight satisfaction and mood results are just as variable. One reason for these inconsistent results might be that different methods of image exposure (e.g., slideshow vs. film) afford varying levels of attention. Therefore, we manipulated attention levels and measured participants' weight satisfaction and food intake. We based our hypotheses on the elaboration likelihood model and on restraint theory. We hypothesised that advertent (i.e., processing the images via central routes of persuasion) and inadvertent (i.e., processing the images via peripheral routes of persuasion) exposure would trigger differing degrees of weight dissatisfaction and dietary disinhibition among restrained eaters (cf. restraint theory). Participants (N = 174) were assigned to one of four conditions: advertent or inadvertent exposure to media or control images. The dependent variables were measured in a supposedly unrelated study. Although restrained eaters' weight satisfaction was not significantly affected by either media exposure condition, advertent (but not inadvertent) media exposure triggered restrained eaters' eating. These results suggest that teaching restrained eaters how to pay less attention to media body ideal images might be an effective strategy in media-literary interventions.

    This study examined the effects of state self-focused attention on sexual arousal and trait self-consciousness on sexual arousal and function in sexually functional (n = 16) and dysfunctional (n = 16) women. Self-focused attention was induced using a 50% reflectant television screen in one of two counterbalanced sessions during which self-report and physiological sexual responses to erotic films were measured. Self-focused attention significantly decreased vaginal pulse amplitude (VPA) responses among sexually functional but not dysfunctional women, and substantially decreased correlations between self-report and VPA measures of sexual arousal. Self-focused attention did not significantly impact subjective sexual arousal in sexually functional or dysfunctional women. Trait private self-consciousness was positively related to sexual desire, orgasm, compatibility, contentment and sexual satisfaction. Public self-consciousness was correlated with sexual pain. The findings are discussed in terms of Masters and Johnson’s [Masters, W. H. & Johnson, V. E. (1970). Human sexual inadequacy. Boston: Little, Brown) concepts of “spectatoring” and “sensate focus.” PMID:15927143

    Mathematics classroom interaction has often been described as an important context for involving all students. However, this article shows that teacher-student-interaction is still not really in the focus of teachers' attention. Based on classroom video studies, some authors hypothesize that the implicitness of establishing norms and practices is, among others, an obstacle for students with low socio-economic status. The article intends to put this hypothesis into perspective by investigating teachers' and students' focus of attention on classroom interaction in video-stimulated group discussions (six discussions with 5-6 students, four discussions with 5-9 teachers). The data analysis used inductive procedures of category development, frequency analysis, and deeper qualitative analysis of the transcripts. For students' focus of attention, differential patterns could be extrapolated: Whereas students of high socio-economic status seem to be more attentive to teacher's contextual expectations, the students of low socio-economic status seem to be more focused on general norms without taking into account contextual expectations. For the teachers, the analysis shows that interactive mechanisms of teacher-student exchanges in classrooms are usually not in the teachers' focus of attention. Additionally, the teachers address, but rarely problematize the implicitness by which norms and practices are established. Together with the differential findings on students' attention, these findings are discussed with respect to equity concerns and consequences for professional development of teachers.

    Speech perception under complex listening conditions usually decreases in aging. This is especially true for listening conditions requiring divided attention among 2 and more relevant speakers. Using a speech perception task and event-related potential measures, we studied the ability of younger and older adults to attend to speech information from a single-target speaker (focused attention) or from 2 different (alternative) target speakers (divided attention). The focused and divided attention conditions were presented either in silence or in the presence of 3 concurrent speakers. In the presence of concurrent speakers, older participants showed worse performance with divided versus focused attention. In contrast, there was no effect of attention condition for the younger adults. Relative to the young, event-related potential analysis in older subjects indicated a decline in preparatory activity for the critical speech information (a delayed and smaller contingent negative variation), and delayed attentional control (indicated by a longer P2 latency). Standardized low-resolution brain electromagnetic tomography revealed that the age-related decline in preparatory activity was associated with reduced activation of medial and superior frontal gyrus and anterior cingulate gyrus. The results suggest that age-related differences in these prefrontal brain areas reflect declines in preparatory attention and gating of subsequent task-related speech information, especially under conditions of divided attention. These findings may reflect mechanisms relating to impaired speech perception by older people in "cocktail-party" listening situations. Copyright © 2016 Elsevier Inc. All rights reserved.

In 2009, new media and its metrics were celebrated as innovations that would increase advertising campaigns overall efficiency. In 2011, this perception has changed: New media’s profusion of metrics, once seen as an advantage, started to compromise its ease of use and adoption. Among its findings, this study argues that there is an opportunity for media groups willing to shift from a product-focused strategy towards a customer-centric one, through the creation of new, simple and integrative metrics.

    Selective attention has been hypothesized to reduce distractor interference at both perceptual and postperceptual levels (Lavie, 2005), respectively, by focusing perceptual resources on the attended location and by blocking at postperceptual levels distractors that survive perceptual selection. This study measured the impact of load on these…

  4. Media attention and the market for "green" consumer products

    DEFF Research Database (Denmark)

    Thøgersen, John

    Environmental protection has been an issue with remarkable staying power on the public agenda in Europe and North America in the past two to three decades (Dunlap, 2002) and many companies have prospered by seizing the opportunities offered by the growing "green" market. However, now...... of drama, and misconduct in businesses with a "green" image has a taste of hypocrisy, both of which make for highly newsworthy events. Hence, despite a large and loyal customer base, many "green" companies now find themselves in a much more hostile environment than a decade ago....... there are signs of a general "counter attack" being or-chestrated against the "greens." In this paper I survey the evidence regarding an "issue-attention" cycle (Downs, 1972) in environmental concern in Western Europe and North America and discus the role of the news media in creating the cycle.

  5. Children's Failure in Analogical Reasoning Tasks: A Problem of Focus of Attention and Information Integration?

    2017-01-01

    Children's improved performance with age in analogy tasks has been explained by an increase in semantic knowledge of the items and the relations between them or by the development of an increased ability to inhibit irrelevant information. We tested the so-called "unbalanced attentional focus hypothesis" that claims that a failure to choose the "analogical" match can be the result of a difficulty to focus on all the relevant information available. Previous eye-tracking research has suggested, in analogies of the A:B::C:D format, that 5-6 year-olds organize their search around the C item. They focused significantly less than adults on the A:B pair, thereby hindering their discovering the relation(s) between A and B. We hypothesized that inducing them to focus their attention on the A:B pair at the beginning of the trial would affect their performance. In Experiment 1, increasing children's focus on the A:B pair did, indeed, lead to better performance. In contrast, in Experiment 2, focusing their attention on the A:B pair impaired performance when the most salient relation holding between A and B was, in fact, irrelevant for the analogy. By contrast, the obvious-but-irrelevant relation in the A:B pair had no negative effect on performance when no explicit A:B focusing was induced. These results are discussed in terms of the temporal organization of the task and availability of information, and of children's difficulties to disengage from the main goal of the task, when necessary.

  6. Focused Flow During Infiltration Into Ethanol-Contaminated Unsaturated Porous Media

    2017-12-01

    The increasing commercial and industrial use of ethanol, e.g. in biofuels, has generated increased incidents of vadose zone contamination by way of ethanol spills and releases. This has increased the interest in better understanding behaviors of ethanol in unsaturated porous media and it's multiphase interactions in the vadose zone. This study uses highly controlled laboratory experiments in a 2-D (0.6mx0.6mx0.01m) flow cell to investigate water infiltration behaviors into ethanol-contaminated porous media. Ethanol and water were applied by either constant head or constant flux methods onto the surface of sands homogenously packed into the flow cell. The constant flux experiments at both low and high application rates were conducted using a rainulator with a row of hypodermic needles connected to a peristaltic pump. The constant head experiments were conducted using an 8cm diameter tension disk infiltrometer set to both low and high tensions. The presence of ethanol contamination generated solute-dependent capillarity induced focused flow (SCIFF) of water infiltration, which was primarily due to decreases in interfacial tensions at the air-liquid interfaces in the unsaturated sands as a function of ethanol concentration. SCIFF was clearly expressed as an unsaturated water flow phenomenon comprised of narrowly focused vertical flow fingers of water within the initially ethanol contaminated porous media. Using analyses of photos and video, comparisons were made between constant flux and constant head application methods. Further comparisons were made between low and high infiltration rates and the two sand textures used. A high degree of sensitivity to minor heterogeneity in relatively homogeneous sands was also observed. The results of this research have implications for rainfall infiltration into ethanol contaminated vadose zones expressing SCIFF, including implications for associated mass fluxes and the nature of flushing of ethanol from the unsaturated zone to

    Full Text Available Simultaneous mobile internet and television usage has been getting very popular. Few, if any, studies explicated generational differences in this type of media multitasking behaviors. This study is the first to examine whether different generations have different behaviors and motives in the mobile internet-television media multitasking context. A national face-to-face survey with the probability proportional to size random sampling method was employed. The results showed that Web generation was most likely to perform mobile internet-television media multitasking behavior, followed by X generation and Baby Boomer generation. Web generation paid most attention to the contents on the mobile Internet, X generation focused their attention on either television or mobile internet, and Baby Boomer generation paid most attention to the contents on television. The results also showed that the motives driving mobile internet-television media multitasking behavior were the same across generations, including “habit and convenience” and “cognition and status.” All these findings supported the proposed theory of cross generation media multitasking behavior and the proposed method of analyzing the motives driving media multitasking behaviors.

  9. Weak surround suppression of the attentional focus characterizes visual selection in the ventral stream in autism

    Directory of Open Access Journals (Sweden)

    Luca Ronconi

    Full Text Available Neurophysiological findings in the typical population demonstrate that spatial scrutiny for visual selection determines a center-surround profile of the attentional focus, which is the result of recurrent processing in the visual system. Individuals with autism spectrum disorder (ASD manifest several anomalies in their visual selection, with strengths in detail-oriented tasks, but also difficulties in distractor inhibition tasks. Here, we asked whether contradictory aspects of perception in ASD might be due to a different center-surround profile of their attentional focus. In two experiments, we tested two independent samples of children with ASD, comparing them with typically developing (TD peers. In Experiment 1, we used a psychophysical task that mapped the entire spatial profile of the attentional focus. In Experiment 2, we used dense-array electroencephalography (EEG to explore its neurophysiological underpinnings. Experiment 1 results showed that the suppression, surrounding the attentional focus, was markedly reduced in children with ASD. Experiment 2 showed that the center-surround profile in TD children resulted in a modulation of the posterior N2 ERP component, with cortical sources in the lateral-occipital and medial/inferior temporal areas. In contrast, children with ASD did not show modulation of the N2 and related activations in the ventral visual stream. Furthermore, behavioural and neurophysiological measures of weaker suppression predicted more severe autistic symptomatology. The present findings, showing an altered center-surround profile during attentional selection, give an important insight to understand superior visual processing in autism as well as the experiencing of sensory overload.

    This study examined the effects of ACTH 4-10, a fragment of adrenocorticotropin (ACTH) with known central nervous system (CNS) activity, on the dimensional complexity of the ongoing electroencephalographic (EEG) activity. Stressful stimuli cause ACTH to be released from the pituitary, and as a neuropeptide ACTH may concurrently exert adaptive influences on the brain's processing of these stimuli. Previous studies have indicated an impairing influence of ACTH on selective attention. Dimensional complexity of the EEG, which indexes the brain's way of stimulus processing, was evaluated while subjects performed tasks with different attention demands. Sixteen healthy men (23 to 33 years) were tested once after placebo and another time after administration of ACTH 4-10 (1.25 mg intravenously (i.v.), 30 minutes before testing). The EEG was recorded while subjects were presented with a dichotic listening task (consisting of the concurrent presentation of tone pips to the left and right ear). Subjects either a) listened to pips in both ears (divided attention), or b) listened selectively to pips in one ear (selective attention), or c) ignored all pips. Dimensional complexity of the EEG was higher during divided than selective attention. ACTH significantly increased the EEG complexity during selective attention, in particular over the midfrontal cortex (Fz, Cz). The effects support the view of a de-focusing action of ACTH during selective attention that could serve to improve the organism's adaptation to stress stimuli.

  11. The Effect of Different Attentional Focus Instructions during Finger Movement Tasks in Healthy Subjects: An Exploratory Study

    Directory of Open Access Journals (Sweden)

    Giacomo Rossettini

    2017-01-01

    Full Text Available External focus of attention (EFA and internal focus of attention (IFA represent commonly used strategies to instruct subjects during exercise. Several studies showed EFA to be more effective than IFA to improve motor performance and learning. To date the role of these strategies on motor performance during finger movement was less studied. The objective of the study was to investigate motor performance, patient’s preference induced by IFA and EFA, and the focus during control condition. Ten healthy right-handed participants performed a finger movement task in control, EFA, and IFA conditions (counterbalanced. Errors, patient’s preference, and type of attentional focus spontaneously adopted during the control condition were recorded. EFA determined less error (p<0.01 compared to control and IFA. Participants preferred EFA against IFA and control condition. In the control group 10% of subjects adopted a purely EFA, 70% of subjects adopted a purely IFA, and 20% of subjects adopted a mixture of the two foci. Our results confirm that EFA is more effective than IFA and control in finger movement task. Due its clinical relevance, the interaction between attention and finger movement should be further investigated.

    Full Text Available The aim of this study was to investigate the effects of different types of feedback on learning soccer “head kick” of female adolescent. Novices performed head kick during two practice days [one week apart for two weeks using either internal or external preference attentional focusing instructions. There was also a preference group who choosen their feedback type themselves. Internal focus feedback related with body movements, whereas external focus feedback related with movement effects. The subjects (N=64 were randomly assigned to three groups internal focus feedback group (IFF (N=15, external focus feedback group (EFF (N=15 and preference group (PF (N=34. To promote learning two skill acquisition days for two weeks and one retention day was applied at initial day of third week. Technique of the skill was measured in acquisition days and targeting was measured in retention day. In technique measuring part, EFF group was significantly more accurate than IFF group, PF group was better than those two groups (PF>EFF>IFF. Similar to acquisition phase, EFF group was significantly more successfull than IFF group, PF group was better than those two groups (PF>EFF>IFF in retention phase. Acquisition and retention phase results indicated significance main effect for attentional focus feedback groups. This study results’ indicated that external focus feedback was more effective than internal focus feedback in terms of acquisition and retention of learning soccer head kick for students with limited amount of knowledge about this skill. This study also indicated that not only the source of attention but also control over to source of attention of preference was an important factor in the amount of retention.

  18. Media multitasking and implicit learning.

    Science.gov (United States)

    Edwards, Kathleen S; Shin, Myoungju

    2017-07-01

    Media multitasking refers to the simultaneous use of different forms of media. Previous research comparing heavy media multitaskers and light media multitaskers suggests that heavy media multitaskers have a broader scope of attention. The present study explored whether these differences in attentional scope would lead to a greater degree of implicit learning for heavy media multitaskers. The study also examined whether media multitasking behaviour is associated with differences in visual working memory, and whether visual working memory differentially affects the ability to process contextual information. In addition to comparing extreme groups (heavy and light media multitaskers) the study included analysis of people who media multitask in moderation (intermediate media multitaskers). Ninety-four participants were divided into groups based on responses to the media use questionnaire, and completed the contextual cueing and n-back tasks. Results indicated that the speed at which implicit learning occurred was slower in heavy media multitaskers relative to both light and intermediate media multitaskers. There was no relationship between working memory performance and media multitasking group, and no relationship between working memory and implicit learning. There was also no evidence for superior performance of intermediate media multitaskers. A deficit in implicit learning observed in heavy media multitaskers is consistent with previous literature, which suggests that heavy media multitaskers perform more poorly than light media multitaskers in attentional tasks due to their wider attentional scope.

  20. Perceptual load vs. dilution: the roles of attentional focus, stimulus category, and target predictability.

    Science.gov (United States)

    Chen, Zhe; Cave, Kyle R

    2013-01-01

    Many studies have shown that increasing the number of neutral stimuli in a display decreases distractor interference. This result has been interpreted within two different frameworks; a perceptual load account, based on a reduction in spare resources, and a dilution account, based on a degradation in distractor representation and/or an increase in crosstalk between the distractor and the neutral stimuli that contain visually similar features. In four experiments, we systematically manipulated the extent of attentional focus, stimulus category, and preknowledge of the target to examine how these factors would interact with the display set size to influence the degree of distractor processing. Display set size did not affect the degree of distractor processing in all situations. Increasing the number of neutral items decreased distractor processing only when a task induced a broad attentional focus that included the neutral stimuli, when the neutral stimuli were in the same category as the target and distractor, and when the preknowledge of the target was insufficient to guide attention to the target efficiently. These results suggest that the effect of neutral stimuli on the degree of distractor processing is more complex than previously assumed. They provide new insight into the competitive interactions between bottom-up and top-down processes that govern the efficiency of visual selective attention.

  1. Three-dimensional focus of attention for iterative cone-beam micro-CT reconstruction

    Benson, T M; Gregor, J

    2006-01-01

    Three-dimensional iterative reconstruction of high-resolution, circular orbit cone-beam x-ray CT data is often considered impractical due to the demand for vast amounts of computer cycles and associated memory. In this paper, we show that the computational burden can be reduced by limiting the reconstruction to a small, well-defined portion of the image volume. We first discuss using the support region defined by the set of voxels covered by all of the projection views. We then present a data-driven preprocessing technique called focus of attention that heuristically separates both image and projection data into object and background before reconstruction, thereby further reducing the reconstruction region of interest. We present experimental results for both methods based on mouse data and a parallelized implementation of the SIRT algorithm. The computational savings associated with the support region are substantial. However, the results for focus of attention are even more impressive in that only about one quarter of the computer cycles and memory are needed compared with reconstruction of the entire image volume. The image quality is not compromised by either method

    Although anxiety is a common non-motor outcome of Parkinson's disease (PD) affecting 40% of patients, little attention has been paid so far to its effects on balance impairment and postural control. Improvement of postural control through focusing on the environment (i.e. external focus) has been reported, but the role of anxiety, as a confounding variable, remains unclear. This study aimed to investigate the influence of anxiety and attentional focus instruction on the standing postural control of PD patients. Thirty-four patients with PD (17 with high anxiety (HA-PD) and 17 with low anxiety (LA-PD)), as well as 17 gender- and age-matched healthy control subjects (HC) participated in the study. Postural control was evaluated using a combination of two levels of postural difficulty (standing on a rigid force plate surface with open eyes (RO) and standing on a foam surface with open eyes (FO)), as well as three attentional focus instructions (internal, external and no focus). Only the HA-PD group demonstrated significant postural control impairment as compared to the control, as indicated by significantly greater postural sway measures. Moreover, external focus significantly reduced postural sway in all participants especially during the FO condition. The results of the current study provide evidence that anxiety influences balance control and postural stability in patients with PD, particularly those with high levels of anxiety. The results also confirmed that external focus is a potential strategy that significantly improves the postural control of these patients. Further investigation of clinical applicability is warranted towards developing effective therapeutic and rehabilitative treatment plans.

    Wild-Wall, Nele; Falkenstein, Michael

    2010-01-01

    By using event-related potentials (ERPs) the present study examines if age-related differences in preparation and processing especially emerge during divided attention. Binaurally presented auditory cues called for focused (valid and invalid) or divided attention to one or both ears. Responses were required to subsequent monaurally presented valid targets (vowels), but had to be suppressed to non-target vowels or invalidly cued vowels. Middle-aged participants were more impaired under divided attention than young ones, likely due to an age-related decline in preparatory attention following cues as was reflected in a decreased CNV. Under divided attention, target processing was increased in the middle-aged, likely reflecting compensatory effort to fulfill task requirements in the difficult condition. Additionally, middle-aged participants processed invalidly cued stimuli more intensely as was reflected by stimulus ERPs. The results suggest an age-related impairment in attentional preparation after auditory cues especially under divided attention and latent difficulties to suppress irrelevant information.

  9. Focused fluorescence excitation with time-reversed ultrasonically encoded light and imaging in thick scattering media

    2013-01-01

    Scattering dominates light propagation in biological tissue, and therefore restricts both resolution and penetration depth in optical imaging within thick tissue. As photons travel into the diffusive regime, typically 1 mm beneath human skin, their trajectories transition from ballistic to diffusive due to the increased number of scattering events, which makes it impossible to focus, much less track, photon paths. Consequently, imaging methods that rely on controlled light illumination are ineffective in deep tissue. This problem has recently been addressed by a novel method capable of dynamically focusing light in thick scattering media via time reversal of ultrasonically encoded (TRUE) diffused light. Here, using photorefractive materials as phase conjugate mirrors, we show a direct visualization and dynamic control of optical focusing with this light delivery method, and demonstrate its application for focused fluorescence excitation and imaging in thick turbid media. These abilities are increasingly critical for understanding the dynamic interactions of light with biological matter and processes at different system levels, as well as their applications for biomedical diagnosis and therapy.

  10. A collective perspective: shared attention and the mind.

    Shteynberg, Garriy

    2017-12-29

    I review the recent literature on shared attention, instances in which one's personal perspective is also another's. As described by Shteynberg [6 •• ], shared attention involves the activation of a psychological perspective that is personal and plural and irreducibly collective-a perspective in which the world is experienced from 'our attention'. When shared attention is perceived, information under shared attention receives deeper cognitive processing. By updating mutual knowledge, shared attention facilitates communication and, quite possibly, the creation of shared attitudes and beliefs. In this review, I focus on the last 5 years of empirical work detailing the cognitive and affective consequences of shared attention. I also highlight empirical work on the relevance of shared attention to pragmatically important challenges, such as the polarizing effects of social and mass media consumption, as well as the cognitive mechanisms behind autism-like traits. In all, the findings underscore the possibility that shared attention is a basic psychological building block of human sociality-a capacity to act collectively with others who share one's reality.

    2006-03-01

    This article outlines reasons why psychologists should concern themselves with media processes, noting how media are central to contemporary life and heavily implicated in the construction of shared understandings of health. We contend that the present research focus is substantially medicalized, privileging the investigation and framing of certain topics, such as the portrayal of health professionals, medical practices, specific diseases and lifestyle-orientated interventions, and restricting attention to social determinants of health as appropriate topics for investigation. We propose an extended agenda for media health research to include structural health concerns, such as crime, poverty, homelessness and housing and social capital.

    Population-level interventions can possibly enhance each other's effects when they are implemented simultaneously. When the plain packaging policy was implemented in Australia, pictorial health warning labels (HWLs) on cigarette packages were also updated and a national mass media campaign was aired. This study examined whether smokers who recalled the media campaign reported more attention to and talking about HWLs. Longitudinal survey data was obtained among Australian adult smokers, aged 18 years and older, from an online consumer panel. One survey wave was conducted before (September 2012) and two waves were conducted after (January 2013 and May 2013) the interventions. The sample was replenished to maintain a sample size of 1000 participants at each wave. Generalized Estimating Equations analyses were performed. Compared to wave 1, attention to HWLs increased at wave 2 (b=0.32, SE=0.06, pCampaign recall was significantly associated with more attention to HWLs (b=0.29, SE=0.05, pcampaign was associated with more attention to and talking about HWLs. When adjusting for campaign recall, there was still an increasing trend in attention and talking. This suggests that the media campaign and the new packaging and labeling policies had independent and positive effects on attention to and talking about HWLs. Copyright © 2015 Elsevier Ltd.

    Background Although anxiety is a common non-motor outcome of Parkinson's disease (PD) affecting 40% of patients, little attention has been paid so far to its effects on balance impairment and postural control. Improvement of postural control through focusing on the environment (i.e. external focus) has been reported, but the role of anxiety, as a confounding variable, remains unclear. Objectives This study aimed to investigate the influence of anxiety and attentional focus instruction on the standing postural control of PD patients. Methods Thirty-four patients with PD (17 with high anxiety (HA-PD) and 17 with low anxiety (LA-PD)), as well as 17 gender- and age-matched healthy control subjects (HC) participated in the study. Postural control was evaluated using a combination of two levels of postural difficulty (standing on a rigid force plate surface with open eyes (RO) and standing on a foam surface with open eyes (FO)), as well as three attentional focus instructions (internal, external and no focus). Results Only the HA-PD group demonstrated significant postural control impairment as compared to the control, as indicated by significantly greater postural sway measures. Moreover, external focus significantly reduced postural sway in all participants especially during the FO condition. Conclusion The results of the current study provide evidence that anxiety influences balance control and postural stability in patients with PD, particularly those with high levels of anxiety. The results also confirmed that external focus is a potential strategy that significantly improves the postural control of these patients. Further investigation of clinical applicability is warranted towards developing effective therapeutic and rehabilitative treatment plans. PMID:29390029

    In this paper, we have experimentally demonstrated light focusing through strongly scattering media by performing binary amplitude optimization with a genetic algorithm. In the experiments, we control 160 000 mirrors of digital micromirror device to modulate and optimize the light transmission paths in the strongly scattering media. We replace the universal target-position-intensity (TPI) discriminant with signal-to-background ratio (SBR) discriminant in genetic algorithm. With 400 incident segments, a relative enhancement value of 17.5% with a ground glass diffuser is achieved, which is higher than the theoretical value of 1/(2π )≈ 15.9 % for binary amplitude optimization. According to our repetitive experiments, we conclude that, with the same segment number, the enhancement for the SBR discriminant is always higher than that for the TPI discriminant, which results from the background-weakening effect of SBR discriminant. In addition, with the SBR discriminant, the diameters of the focus can be changed ranging from 7 to 70 μm at arbitrary positions. Besides, multiple foci with high enhancement are obtained. Our work provides a meaningful reference for the study of binary amplitude optimization in the wavefront shaping field.

    2009-01-01

    Alcohol in the media influences norms around use, particularly for young people. A recent spate of celebrity arrests for drinking and driving (DUI) has received considerable media attention. We asked whether these newsworthy events serve as teachable moments or problematic social modeling for young women. Qualitative analysis of US media coverage of four female celebrities (Michelle Rodriguez, Paris Hilton, Nicole Richie and Lindsay Lohan) was conducted over the year following their DUI arrest (December 2005 through June 2008). The media sample included five television and three print sources and resulted in 150 print and 16 television stories. Stories were brief, episodic and focused around glamorous celebrity images. They included routine discussion of the consequences of the DUI for the individual celebrities without much evidence of a consideration of the public health dimensions of drinking and driving or possible prevention measures. Our analysis found little material in the media coverage that dealt with preventing injury or promoting individual and collective responsibility for ensuring such protection. Media attention to such newsworthy events is a missed opportunity that can and should be addressed through media advocacy efforts.

  16. Information paradox of new product development: A case of decision-makers' focus of attention

    DEFF Research Database (Denmark)

    Jespersen, Kristina Risom

    Drawing on theory of bounded rationality and the attention-based view of the company, decision-makers' focus of attention is examined within the new product development process. Attention, defined as something which occupies individual consciousness, should be directed at selecting development...... activities and applying information resulting from these activities to go/no-go decision-making. Based on the information behavior of 42 development managers collected through a virtual role-play simulation of new product development, this research finds two information paradoxes of new product development....... First, competitive behavior makes decision-makers apply logic of reassurances in their implementation of NPD activities. Second, the information processing competence of decision-makers is unbalanced as information increases uncertainty in the concrete decision-making situation....

    Current clinical models emphasize certain cognitive processes in the maintenance of distressing paranoia. While a number of these processes have been examined in detail, the role of strategic cognition and self-focused attention remain under-researched. This study examined the deployment of cognitive strategies and self-focused attention in people with non-clinical paranoia. An experimental design was used to examine the impact of a threat activation task on these processes, in participants with high and low non-clinical paranoia. Twenty-eight people were recruited to each group, and completed measures of anxiety, paranoid cognition, strategic cognition and self-focused attention. The threat activation task was effective in increasing anxiety in people with high and low non-clinical paranoia. The high paranoia group experienced more paranoid cognitions following threat activation. This group also reported greater use of thought suppression, punishment and worry, and less use of social control strategies when under threat. No differences were found between the groups on measures of self-focused attention. This study shows that the threat activation task increased anxiety in people with high non-clinical paranoia, leading to increased paranoid thinking. The use of strategic cognition following threat activation varied dependent on level of non-clinical paranoia. If these differences are replicated in clinical groups, the strategies may be implicated in the maintenance of distressing psychosis, and may therefore be a valuable target for therapeutic intervention.

    2016-10-01

    The concept of attention has a prominent place in cognitive psychology. Attention can be directed not only to perceptual information, but also to information in working memory (WM). Evidence for an internal focus of attention has come from the retro-cue effect: Performance in tests of visual WM is improved when attention is guided to the test-relevant contents of WM ahead of testing them. The retro-cue paradigm has served as a test bed to empirically investigate the functions and limits of the focus of attention in WM. In this article, we review the growing body of (behavioral) studies on the retro-cue effect. We evaluate the degrees of experimental support for six hypotheses about what causes the retro-cue effect: (1) Attention protects representations from decay, (2) attention prioritizes the selected WM contents for comparison with a probe display, (3) attended representations are strengthened in WM, (4) not-attended representations are removed from WM, (5) a retro-cue to the retrieval target provides a head start for its retrieval before decision making, and (6) attention protects the selected representation from perceptual interference. The extant evidence provides support for the last four of these hypotheses.

  1. A single bout of meditation biases cognitive control but not attentional focusing: Evidence from the global-local task.

    Science.gov (United States)

    Colzato, Lorenza S; van der Wel, Pauline; Sellaro, Roberta; Hommel, Bernhard

    2016-01-01

    Recent studies show that a single bout of meditation can impact information processing. We were interested to see whether this impact extends to attentional focusing and the top-down control over irrelevant information. Healthy adults underwent brief single bouts of either focused attention meditation (FAM), which is assumed to increase top-down control, or open monitoring meditation (OMM), which is assumed to weaken top-down control, before performing a global-local task. While the size of the global-precedence effect (reflecting attentional focusing) was unaffected by type of meditation, the congruency effect (indicating the failure to suppress task-irrelevant information) was considerably larger after OMM than after FAM. Our findings suggest that engaging in particular kinds of meditation creates particular cognitive-control states that bias the individual processing style toward either goal-persistence or cognitive flexibility.

    This study examined the dissociable neural effects of ānāpānasati (focused-attention meditation, FAM) and mettā (loving-kindness meditation, LKM) on BOLD signals during cognitive (continuous performance test, CPT) and affective (emotion-processing task, EPT, in which participants viewed affective pictures) processing. Twenty-two male Chinese expert meditators (11 FAM experts, 11 LKM experts) and 22 male Chinese novice meditators (11 FAM novices, 11 LKM novices) had their brain activity monitored by a 3T MRI scanner while performing the cognitive and affective tasks in both meditation and baseline states. We examined the interaction between state (meditation vs. baseline) and expertise (expert vs. novice) separately during LKM and FAM, using a conjunction approach to reveal common regions sensitive to the expert meditative state. Additionally, exclusive masking techniques revealed distinct interactions between state and group during LKM and FAM. Specifically, we demonstrated that the practice of FAM was associated with expertise-related behavioral improvements and neural activation differences in attention task performance. However, the effect of state LKM meditation did not carry over to attention task performance. On the other hand, both FAM and LKM practice appeared to affect the neural responses to affective pictures. For viewing sad faces, the regions activated for FAM practitioners were consistent with attention-related processing; whereas responses of LKM experts to sad pictures were more in line with differentiating emotional contagion from compassion/emotional regulation processes. Our findings provide the first report of distinct neural activity associated with forms of meditation during sustained attention and emotion processing. PMID:22905090

  3. Tactus ≠ Tempo: Some Dissociations Between Attentional Focus, Motor Behavior, and Tempo Judgment

    2011-08-01

    Full Text Available Three experiments explored the relationships between surface rhythmic activity, tactus or beat rate, attentional focus, sensorimotor synchronization (tapping, and tempo perception. All involved a rhythmic standard followed by a comparison; the experimental task was a judgment of “slower, same, or faster.” In Experiment 1 participants simply judged relative speed; they focused on the beat level in Experiment 2, and they tapped along as they made their judgments in Experiment 3. In all three experiments judgments were highly accurate (89-97% correct, relative to beat-level inter-onset interval when the standard-comparison involved the same pattern/same tempo, and performed similarly for the same pattern at different tempos (80-83% correct. Performance degraded significantly in other contexts, especially for different patterns at the same tempo. A main effect for pattern (two levels: same vs. different and a pattern x tempo interaction were observed in all three experiments; a main effect for tempo (collapsed to two levels: same vs. different occurred only in Experiment 1. Analysis of a subset of the experimental conditions indicated that surface activity was of greater salience than the beat level in some contexts. Tapping along (Experiment 3 did not improve overall performance any more than simply focusing on the tactus level (Experiment 2, and a possible biasing effect of tapping rate on tempo judgment was observed. Thus there is an apparent dissociation between tactus rate, attentional focus, tapping behavior and tempo judgment. This suggests that our perception of musical speed or tempo is more than simple apprehension of the tactus rate.

  4. Searching for serial refreshing in working memory: Using response times to track the content of the focus of attention over time.

    2016-12-01

    One popular idea is that, to support the maintenance of a set of elements over brief periods of time, the focus of attention rotates among the different elements, thereby serially refreshing the content of working memory (WM). In the research reported here, probe letters were presented between to-be-remembered letters, and response times to these probes were used to infer the status of the different items in WM. If the focus of attention cycles from one item to the next, its content should be different at different points in time, and this should be reflected in a change in the response time patterns over time. Across a set of four experiments, we demonstrated a striking pattern of invariance in the response time patterns over time, suggesting either that the content of the focus of attention did not change over time or that response times cannot be used to infer the content of the focus of attention. We discuss how this pattern constrains models of WM, attention, and human information processing.

  5. Attention to memory: orienting attention to sound object representations.

    Backer, Kristina C; Alain, Claude

    2014-01-01

    Despite a growing acceptance that attention and memory interact, and that attention can be focused on an active internal mental representation (i.e., reflective attention), there has been a paucity of work focusing on reflective attention to 'sound objects' (i.e., mental representations of actual sound sources in the environment). Further research on the dynamic interactions between auditory attention and memory, as well as its degree of neuroplasticity, is important for understanding how sound objects are represented, maintained, and accessed in the brain. This knowledge can then guide the development of training programs to help individuals with attention and memory problems. This review article focuses on attention to memory with an emphasis on behavioral and neuroimaging studies that have begun to explore the mechanisms that mediate reflective attentional orienting in vision and more recently, in audition. Reflective attention refers to situations in which attention is oriented toward internal representations rather than focused on external stimuli. We propose four general principles underlying attention to short-term memory. Furthermore, we suggest that mechanisms involved in orienting attention to visual object representations may also apply for orienting attention to sound object representations.

    2015-04-01

    Full Text Available The quest to make sense of media’s impact—what it does to us—dominates communication theories and popular discourse about media. But the impulse to collar, cultivate, domesticate, or measure the impact of media on individuals and society can have pernicious effects, too. This essay calls for a set of new analytical models to account for media as messy instantiations of social interaction transforming before our very eyes. We need to shift from a media effects paradigm that narrowly focuses on the brightest signals of social media use and turn to what I will call here a curatorial theory of social media. This approach, inspired by research from several founding editors of Social Media + Society , focuses on media’s cultural work and myriad manifestations—from its technologies to the discourses that flow through and from them. Let us attend to the more elusive, noisy cultural and social forces that bring some aspects of media sharply into focus while obscuring others. And, above all, let us pay attention to the curatorial reworking of media that happens in particular places—nations, towns, bodies.

    Lui, Kelvin F H; Wong, Alan C-N

    2012-08-01

    Heavy media multitaskers have been found to perform poorly in certain cognitive tasks involving task switching, selective attention, and working memory. An account for this is that with a breadth-biased style of cognitive control, multitaskers tend to pay attention to various information available in the environment, without sufficient focus on the information most relevant to the task at hand. This cognitive style, however, may not cause a general deficit in all kinds of tasks. We tested the hypothesis that heavy media multitaskers would perform better in a multisensory integration task than would others, due to their extensive experience in integrating information from different modalities. Sixty-three participants filled out a questionnaire about their media usage and completed a visual search task with and without synchronous tones (pip-and-pop paradigm). It was found that a higher degree of media multitasking was correlated with better multisensory integration. The fact that heavy media multitaskers are not deficient in all kinds of cognitive tasks suggests that media multitasking does not always hurt.

    To identify ways to effectively use social media to communicate nutrition-related information to low-income populations. The authors conducted 4 focus groups with female Expanded Food and Nutrition Education Program graduates who used social media at least twice a week (n = 26 total). Transcripts were analyzed using the constant comparative method to identify key themes. For participants, page content, page maintenance, and networking opportunities with others were important aspects of a nutrition education social media page. Trust emerged as a central theme, because participants expressed a need for reliable information from known, credible sources and safe places to share ideas. Using social media to provide nutrition-related messages may be an effective way to encourage sustained positive behavior changes resulting from educational programming and to engage participants beyond class time. Establishing the trustworthiness of the social media site is essential to its use among low-income participants. Copyright © 2014 Society for Nutrition Education and Behavior.

    The current study investigated the mediating role of fear of negative evaluation on the relationship between self-focused attention and self-esteem among college students with and without asthma. Young adults with (n = 148) and without (n = 530) childhood-onset asthma were recruited from a college student population. Self-focused attention and fear of negative evaluation measures were completed. Participants also answered questions about inclusion in a social activity. Higher levels of self-focused attention and fear of negative evaluation were associated with lower self-esteem in both groups within the context of social activity participation. Fear of negative evaluation mediated the relationship between self-consciousness and self-esteem. No significant differences were found between groups. Findings indicate significant relationships among self-focused attention, fear of negative evaluation, and self-esteem in the context of social activity participation. Further examination of self-esteem regarding participation in social activities among college students appears warranted.

    Traditional measures of the impact of published research, such as citation counts, are limited to measuring academic impact. The use of social media and other online tools as alternative measures of research impact is gaining popularity and used by leading medical journals. MEDLINE was searched for articles published with subject headings relating to solid organ transplantation between August 1, 2011, and July 31, 2012. Citation data were retrieved from SCOPUS, and statistics regarding mentions in social media, social bookmarking sites, news outlets, and expert recommendation sites were retrieved from the data at www.altmetric.com. Data were analyzed for associations between alternative metric data and citation rates. The search retrieved 6,981 publications. Sixty-six percent of the articles had at least one citation. Mentions in social media were 19.3%, 13.1% had social bookmarks, 0.9% had expert recommendations, and online news outlets picked up eight articles. Significantly higher citation rates were associated with mention in social media, expert recommendation, social bookmarking, and for articles identified as meta-analyses, multicenter studies, randomized controlled trials, and reviews (all Psocial media (odds ratio, 2.58; Psocial media are more likely to relate to the more controversial and emotive areas of transplantation. Social media and online attention act as early predictors of the impact of transplant research as measured by later citation rate. Blogging and expert recommendation, in particular, are associated with higher citation rates.

    Working memory (WM) is imperative for effective selective attention. Distractibility is greater under conditions of high (vs. low) concurrent working memory load (WML), and in individuals with low (vs. high) working memory capacity (WMC). In the current experiments, we recorded the flanker task performance of individuals with high and low WMC during low and high WML, to investigate the combined effect of WML and WMC on selective attention. In Experiment 1, distractibility from a distractor at a fixed distance from the target was greater when either WML was high or WMC was low, but surprisingly smaller when both WML was high and WMC low. Thus we observed an inverted-U relationship between reductions in WM resources and distractibility. In Experiment 2, we mapped the distribution of spatial attention as a function of WMC and WML, by recording distractibility across several target-to-distractor distances. The pattern of distractor effects across the target-to-distractor distances demonstrated that the distribution of the attentional window becomes dispersed as WM resources are limited. The attentional window was more spread out under high compared to low WML, and for low compared to high WMC individuals, and even more so when the two factors co-occurred (i.e., under high WML in low WMC individuals). The inverted-U pattern of distractibility effects in Experiment 1, replicated in Experiment 2, can thus be explained by differences in the spread of the attentional window as a function of WM resource availability. The current findings show that limitations in WM resources, due to either WML or individual differences in WMC, affect the spatial distribution of attention. The difference in attentional constraining between high and low WMC individuals demonstrated in the current experiments helps characterise the nature of previously established associations between WMC and controlled attention.

    2006-01-01

    There is a burgeoning interest in the health and illness content of popular media in the domains of advertising, journalism, and entertainment. This article reviews the past 10 years of this research, describing the relationship between the health topics addressed in the research, the shifting focus of concerns about the media, and, ultimately, the variation in problems for health promotion. I suggest that research attending to topics related to bodily health challenges focused on whether popular media accurately or appropriately represented health challenges. The implication was that there is some consensus about more right or wrong, complete or incomplete ways of representing an issue; the problem was that the media are generally wrong. Alternatively, research addressing topics related to sociocultural context issues focused on how certain interests are privileged in the media. The implication was that competing groups are making claims on the system, but the problem was that popular media marginalizes certain interests. In short, popular media is not likely to facilitate understandings helpful to individuals coping with health challenges and is likely to perpetuate social and political power differentials with regard to health-related issues. I conclude by offering some possibilities for future health media content research.

  1. Neural Evidence for a Distinction between Short-Term Memory and the Focus of Attention

    It is widely assumed that the short-term retention of information is accomplished via maintenance of an active neural trace. However, we demonstrate that memory can be preserved across a brief delay despite the apparent loss of sustained representations. Delay period activity may, in fact, reflect the focus of attention, rather than STM. We…

  2. Topicality and impact in social media: diverse messages, focused messengers.

    2015-01-01

    We have a limited understanding of the factors that make people influential and topics popular in social media. Are users who comment on a variety of matters more likely to achieve high influence than those who stay focused? Do general subjects tend to be more popular than specific ones? Questions like these demand a way to detect the topics hidden behind messages associated with an individual or a keyword, and a gauge of similarity among these topics. Here we develop such an approach to identify clusters of similar hashtags in Twitter by detecting communities in the hashtag co-occurrence network. Then the topical diversity of a user's interests is quantified by the entropy of her hashtags across different topic clusters. A similar measure is applied to hashtags, based on co-occurring tags. We find that high topical diversity of early adopters or co-occurring tags implies high future popularity of hashtags. In contrast, low diversity helps an individual accumulate social influence. In short, diverse messages and focused messengers are more likely to gain impact.

    When a test of working memory (WM) requires the retention of multiple items, a subset of them can be prioritized. Recent studies have shown that, although prioritized (i.e., attended) items are associated with active neural representations, unprioritized (i.e., unattended) memory items can be retained in WM despite the absence of such active representations, and with no decrement in their recognition if they are cued later in the trial. These findings raise two intriguing questions about the nature of the short-term retention of information outside the focus of attention. First, when the focus of attention shifts from items in WM, is there a loss of fidelity for those unattended memory items? Second, could the retention of unattended memory items be accomplished by long-term memory mechanisms? We addressed the first question by comparing the precision of recall of attended versus unattended memory items, and found a significant decrease in precision for unattended memory items, reflecting a degradation in the quality of those representations. We addressed the second question by asking subjects to perform a WM task, followed by a surprise memory test for the items that they had seen in the WM task. Long-term memory for unattended memory items from the WM task was not better than memory for items that had remained selected by the focus of attention in the WM task. These results show that unattended WM representations are degraded in quality and are not preferentially represented in long-term memory, as compared to attended memory items.

  6. The Improvement of Emotion and Attention Regulation after a 6-Week Training of Focused Meditation: A Randomized Controlled Trial

    Full Text Available Self-regulatory trainings can be an effective complementary treatment for mental health disorders. We investigated the effects of a six-week-focused meditation training on emotion and attention regulation in undergraduates randomly allocated to a meditation, a relaxation, or a wait-list control group. Assessment comprised a discrimination task that investigates the relationship between attentional load and emotional processing and self-report measures. For emotion regulation, results showed greater reduction in emotional interference in the low attentional load condition in meditators, particularly compared to relaxation. Only meditators presented a significant association between amount of weekly practice and the reduction in emotion interference in the task and significantly reduced image ratings of negative valence and arousal, perceived anxiety and difficulty during the task, and state and trait-anxiety. For attention regulation, response bias during the task was analyzed through signal detection theory. After training, meditation and relaxation significantly reduced bias in the high attentional load condition. Importantly, there was a dose-response effect on general bias: the lowest in meditation, increasing linearly across relaxation and wait-list. Only meditators reduced omissions in a concentrated attention test. Focused meditation seems to be an effective training for emotion and attention regulation and an alternative for treatments in the mental health context.

  7. Flexibility within working memory and the focus of attention for sequential verbal information does not depend on active maintenance.

    2014-10-01

    The focus of attention seems to be a static element within working memory when verbal information is serially presented, unless additional time is available for processing or active maintenance. Experiment 1 manipulated the reward associated with early and medial list positions in a probe recognition paradigm and found evidence that these nonterminal list positions could be retrieved faster and more accurately if participants were appropriately motivated-without additional time for processing or active maintenance. Experiment 2 used articulatory suppression and demonstrated that the underlying maintenance mechanism cannot be attributed to rehearsal, leaving attentional refreshing as the more likely mechanism. These findings suggest that the focus of attention within working memory can flexibly maintain nonterminal early and medial list representations at the expense of other list representations even when there is not additional time for processing or active maintenance. Maintenance seems to be accomplished through an attentional refreshing mechanism.

    2014-01-07

    Over the last decade healthcare management and managers have increasingly been in focus in public debate. The purpose of the present study was to gain a deeper understanding of how prolonged, unfavorable media focus can influence both the individual as a person and his or her managerial practice in the healthcare organization. In-depth interviews (n = 49) with 24 managers and their superiors, or subordinate human resources/information professionals, and partners were analyzed using a grounded theory approach. The conceptual model explains how perceived uncertainties related to the managerial role influence personification and its negative consequences. The role ambiguities comprised challenges regarding the separation of individual identity from the professional function, the interaction with intra-organizational support and political play, and the understanding and acceptance of roles in society. A higher degree of uncertainty in role ambiguity increased both personification and the personal reaction to intense media pressure. Three types of reactions were related to the feeling of being infringed: avoidance and narrow-mindedness; being hard on self, on subordinates, and/or family members; and resignation and dejection. The results are discussed so as to elucidate the importance of support from others within the organization when under media scrutiny. The degree of personification seems to determine the personal consequences as well as the consequences for their managerial practice. Organizational support for managers appearing in the media would probably be beneficial for both the manager and the organization.

    2014-01-01

    The authors examined how varying the content of verbal-motor instructions and requesting an internal versus external focus influenced the kinematics and outcome of a golf putting task. On Day 1, 30 novices performed 120 trials with the instruction to focus attention either on performing a pendulum-like movement (internal) or on the desired ball path (external). After 20 retention trials on Day 2, they performed 20 transfer trials with the opposite instruction. Group differences for retention and a group by block interaction showed that external instruction enhanced movement outcome. Kinematic data indicated that specific instruction content influenced outcomes by eliciting changes in movement execution. Switching from the external to the internal focus instruction resulted in a more pendulum-like movement.

    2017-07-30

    Obsessive-compulsive disorder (OCD) is characterized by excessive absorption with internally-generated distressing thoughts and urges, with difficulty incorporating external information running counter to their fears and concerns. In the present study, we experimentally probed this core feature of OCD through the use of a novel attention switching task that investigates transitions between internally focused (IF) and externally focused (EF) attentional states. Eighteen OCD patients and 18 controls imagined positive and negative personal event scenarios (IF state) or performed a color-word Stroop task (EF state). The IF/EF states were followed by a target detection (TD) task requiring responses to external stimuli. Compared to controls, OCD patients made significantly more errors and showed reduced activation of superior and inferior occipital cortex, thalamus, and putamen during TD following negative IF, with the inferior occipital hypoactivation being significantly greater for TD following negative IF compared to TD following the other conditions. Patients showed stronger functional connectivity between the inferior occipital region and dorsomedial prefrontal cortex. These findings point to an OCD-related impairment in the visual processing of external stimuli specifically when they follow a period of negative internal focus, and suggest that future treatments may wish to target the transition between attentional states.

    Mindfulness meditation is a form of attention control training. The training exercises the ability to repeatedly focus attention. We addressed the activation changes related to an 8-weeks mindfulness-oriented focused attention meditation training on an initially naïve subject cohort. Before and after training participants underwent an fMRI experiment, thus, although not strictly a cross over design, they served as their internal own control. During fMRI they exercised focused attention on breathing and body scan as compared to resting. We found increased and decreased activation in different parts of the prefrontal cortex (PFC) by comparing pre- vs. post-mindfulness training (MT) during breathing and body scan meditation exercises that were compared against their own resting state. In the post-MT (vs. pre-MT) meditation increased activation in the right dorsolateral PFC and in the left caudate/anterior insula and decreased activation in the rostral PFC and right parietal area 3b. Thus a brief mindfulness training caused increased activation in areas involved in sustaining and monitoring the focus of attention (dorsolateral PFC), consistent with the aim of mindfulness that is exercising focused attention mechanisms, and in the left caudate/anterior insula involved in attention and corporeal awareness and decreased activation in areas part of the "default mode" network and is involved in mentalizing (rostral PFC), consistent with the ability trained by mindfulness of reducing spontaneous mind wandering.

  12. Judicial Perceptions of Media Portrayals of Offenders with High Functioning Autistic Spectrum Disorders.

    Science.gov (United States)

    Berryessa, Colleen M

    In recent years, sensational media reporting focusing on crimes committed by those diagnosed with or thought to have High Functioning Autistic Spectrum Disorders (hfASDs) has caused societal speculation that there is a link between the disorder and violent criminality. No research exists on how and if the judiciary understands and is affected by this coverage. Therefore this study aims to examine how judges perceive and are influenced by media attention surrounding hfASDs and criminality. Semi-structured interviews were conducted with 21 California Superior Court Judges, including questions on media portrayal. Judges perceived general media portrayals of hfASDs in both positive and negative ways. However, almost all judges who had experienced media coverage surrounding hfASDs and criminality identified it as misleading and harmful to public perceptions of the disorder. These findings suggest judges are not exempt from media attention surrounding violence and hfASDs, and they recognize the potential adverse effects of this negative coverage. Although judges' report their opinions are not affected, the results demonstrate that judges are worried that the public and potentially other criminal justice actors are adversely affected and will continue to be moving forward.

  14. High-speed single-shot optical focusing through dynamic scattering media with full-phase wavefront shaping

    2017-11-01

    In biological applications, optical focusing is limited by the diffusion of light, which prevents focusing at depths greater than ˜1 mm in soft tissue. Wavefront shaping extends the depth by compensating for phase distortions induced by scattering and thus allows for focusing light through biological tissue beyond the optical diffusion limit by using constructive interference. However, due to physiological motion, light scattering in tissue is deterministic only within a brief speckle correlation time. In in vivo tissue, this speckle correlation time is on the order of milliseconds, and so the wavefront must be optimized within this brief period. The speed of digital wavefront shaping has typically been limited by the relatively long time required to measure and display the optimal phase pattern. This limitation stems from the low speeds of cameras, data transfer and processing, and spatial light modulators. While binary-phase modulation requiring only two images for the phase measurement has recently been reported, most techniques require at least three frames for the full-phase measurement. Here, we present a full-phase digital optical phase conjugation method based on off-axis holography for single-shot optical focusing through scattering media. By using off-axis holography in conjunction with graphics processing unit based processing, we take advantage of the single-shot full-phase measurement while using parallel computation to quickly reconstruct the phase map. With this system, we can focus light through scattering media with a system latency of approximately 9 ms, on the order of the in vivo speckle correlation time.

    Background: Studies in children and adolescents have associated early developmental manganese (Mn) exposure with inattention, impulsivity, hyperactivity, and oppositional behaviors, but causal inferences are precluded by the correlational nature of the data and generally limited control for potential confounders. Objectives: To determine whether early postnatal oral Mn exposure causes lasting attentional and impulse control deficits in adulthood, and whether continued lifelong Mn exposure exacerbates these effects, using a rat model of environmental Mn exposure. Methods: Neonates were exposed orally to 0, 25 or 50 mg Mn/kg/day during early postnatal life (PND 1–21) or throughout life from PND 1 until the end of the study. In adulthood, the animals were tested on a series of learning and attention tasks using the five-choice serial reaction time task. Results: Early postnatal Mn exposure caused lasting attentional dysfunction due to impairments in attentional preparedness, selective attention, and arousal regulation, whereas associative ability (learning) and impulse control were spared. The presence and severity of these deficits varied with the dose and duration of Mn exposure. Conclusions: This study is the first to show that developmental Mn exposure can cause lasting impairments in focused and selective attention and arousal regulation, and to identify the specific nature of the impairments. Given the importance of attention and arousal regulation in cognitive functioning, these findings substantiate concerns about the adverse effects of developmental Mn exposure in humans.

    Despite advances in imaging diagnosis, contrast media still play an important role in diagnosing the existence of the disease, demonstrating the extent of disease, and determining the perfusion of the disease, which is important to make a differential diagnosis. However, the administration of contrast media may cause contrast-induced nephropathy (CIN), especially in patients with renal impairment. It is estimated that 20-30% of patients with renal impairment who received contrast media develop CIN. Though the precise cause of CIN currently remains unknown, almost all injected contrast media are excreted through the kidney and the effects of contrast media on the kidney are easily understood. As CIN is the most common cause of death due to complications after receiving contrast media, prevention of CIN is important. There are several known risk factors for CIN. Patients with renal impairment, diabetes mellitus, and dehydration are at high risk for CIN. Furthermore, a high osmolar contrast media, excessive amount of contrast media, and ionic contrast media are also risk factors for CIN. CIN can be prevented in several ways. Certain drugs seem to be useful to prevent CIN, while others are harmful. Hydration is useful to prevent CIN, although there is no widely acceptable hydration method to prevent CIN. Both sodium bicarbonate and N-acetylcysteine are promising candidates for prevention of CIN. There are few reports to study CIN after intravenous administration, although reports of CIN after percutaneous cardiac intervention (PCI) and angiography are well recognized. In clinical situations, intravenous administration of contrast media is common. Therefore, a study of CIN after intravenous administration of contrast media should be performed. (author)

    2012-01-01

    Despite large-scale investments and government mandates to expand biofuels development and infrastructure in the United States, little is known about how the public conceives of this alternative fuel technology. This study examines public opinion of biofuels by focusing on citizen knowledge and the motivated processing of media information. Specifically, we explore the direct effects of biofuels knowledge and the moderating effect of partisanship on the relationship between media use and benefit vs. risk perceptions in the following four domains: environmental impacts, economic consequences, ethical/social implications, and political ramifications. Our results suggest that more knowledgeable respondents see fewer benefits of biofuels relative to risks, and that Democrats and Republicans are affected differently by media use when forming opinions about biofuels. Among Democrats, greater attention to political media content leads to a more favorable outlook toward the technology across several domains of interest, while among Republicans, an increase in attention to political content has the opposite effect. Possible reasons for these results, as well as implications of the findings at the intersection of politics and the life sciences, are discussed.

    The purpose of this study was to investigate whether using different focus affects electromyographic (EMG) amplitude and contraction duration during bench press performed at explosive and controlled speeds. Eighteen young male individuals were familiarized with the procedure and performed the one-maximum repetition (1RM) test in the first session. In the second session, participants performed the bench press exercise at 50% of the 1RM with 3 different attentional focuses (regular focus on moving the load vs contracting the pectoralis vs contracting the triceps) at 2 speed conditions (controlled vs maximal speed). During the controlled speed condition, focusing on using either the pectoralis or the triceps muscles increased pectoralis normalized EMG (nEMG) by 6% (95% CI 3-8%; p = 0.0001) and 4% nEMG (95% CI 1-7%; p = 0.0096), respectively, compared with the regular focus condition. Triceps activity was increased by 4% nEMG (95% CI 0-7%; p = 0.0308) at the controlled speed condition during the triceps focus. During the explosive speed condition, the use of different focuses had no effect. The different attentional focus resulted in comparable contraction duration for the measured muscles when the exercise was performed explosively. Using internal focus to increase EMG amplitude seems to function only during conditions of controlled speed.

    2011-01-01

    Perceptions of sensation and pain in healthy people are believed to be the net result of sensory input and descending modulation from brainstem and cortical regions depending on emotional and cognitive factors. Here, the influence of attention on neural activity in the spinal cord during thermal sensory stimulation of the hand was investigated with functional magnetic resonance imaging by systematically varying the participants' attention focus across and within repeated studies. Attention states included (1) attention to the stimulus by rating the sensation and (2) attention away from the stimulus by performing various mental tasks of watching a movie and identifying characters, detecting the direction of coherently moving dots within a randomly moving visual field and answering mentally-challenging questions. Functional MRI results spanning the cervical spinal cord and brainstem consistently demonstrated that the attention state had a significant influence on the activity detected in the cervical spinal cord, as well as in brainstem regions involved with the descending analgesia system. These findings have important implications for the detection and study of pain, and improved characterization of the effects of injury or disease. Copyright © 2011 Elsevier Inc. All rights reserved.

    Full Text Available Trust is the basic element of civil society.For the last decades Ukrainian social institutions, including mass media, suffering of the crisis of trust. Public informing, socialization, formation of public opinion are the main functions of mass media. Mass media takes part in a lot of social processes and spheres of society. Accuracy of the information, compliance with standards,objectivity and trust of the audience are very important because of the influence of the mass media. The paper deals with various interpretations of trust and theories of N.Luhmann, P. Sztompka and A. Seligmen, thatemphasize the importance of trust during the transformation of society. Also author considers the approaches to defining levels of trust. Attention was focused on two levels – the micro-level which represents personal trust and the macro-level with institutional trust. Author analyzes mass media as a social institution and considers social media as a type of mass media, which has its own unique characteristics such as high level of the informational participation, lack of the law regulation and the organizational structure. These characteristics bring to the foreground figure of the author. So the social media covers both levels of forming a trusting relationship with audience – micro and macrolevel.

Thirteen basketball players (body mass = 73,4 kg, height = 186,58 cm, age = 15.12 ± 0.61 y volunteered as participants. All the subject represented a club which participated in the Croatian cadets 1. league in season 2008/09, and were tested during the season. The subjects performed two experiments. In both experiments, they performed 15 repetitions of countermovement jump, whereas in one of the experiments, during the performance of the jumps they were listening to an audio record of spectators. For both type of jumps, the subjects were instructed to stay in the air as long as possible during a single jump (external focus of attention. To determine the differences between jumps, a paired-sample t-test was used with a level of statistical significance set to p ≤ 0.05. Comparison for jump height between both type of jumps revealed no statistically significant difference, although the presented difference should not be denied considering a real match conditions.

    2015-01-01

    The purpose of the current experiment was to distinguish between the impact of strategic and affective forms of gain- and loss-related motivational states on the attention to negative stimuli. On the basis of the counter-regulation principle and regulatory focus theory, we predicted that individuals would attend more to negative than to neutral stimuli in a prevention focus and when experiencing challenge, but not in a promotion focus and under threat. In one experiment (N = 88) promotion, prevention, threat, or challenge states were activated through a memory task, and a subsequent dot probe task was administered. As predicted, those in the prevention focus and challenge conditions had an attentional bias towards negative words, but those in promotion and threat conditions did not. These findings provide support for the idea that strategic mindsets (e.g., regulatory focus) and hot emotional states (e.g., threat vs. challenge) differently affect the processing of affective stimuli.

    Public level of familiarity with nanotechnology partly determines their acceptance or rejection of the technology. This study examines the differential influence of public attention to science news in the media and reflective integration on perceived familiarity with nanotechnology among people in the higher and lower socioeconomic status (SES) groups in Singapore. Significant three-way interactions among education, science news attention, and reflective integration variables were found. Attention to television science news narrowed the level of perceived familiarity with nanotechnology between the higher and lower SES groups for those who engaged in high elaborative processing. Science newspaper attention, on the other hand, widened the familiarity gap between the higher and lower SES groups among those who engaged in high elaborative processing. Two-way interaction among education and elaborative processing were found—elaborative processing closed the familiarity gap between higher and lower SES groups. Theoretical and practical implications were discussed

    Horton-Salway, Mary

    2013-08-01

    Discursive psychology is used to study the gendering of attention deficit hyperactivity disorder in UK national newspapers in the period of 2009-2011. The analysis examines how gendering is embedded in causal attributions and identity constructions. Attention deficit hyperactivity disorder is portrayed as a predominantly male phenomenon with representations of attention deficit hyperactivity disorder being gendered through extreme stories about victims, villains or heroes that depict boys and men as marginalised, exceptional or dangerous. There is also a focus on mothers as the spokespersons and caretakers for parenting and family health while fathers are rendered more invisible. This contributes to our understanding of how attention deficit hyperactivity disorder is constructed in the media using a range of gendered representations that draw on cultural stereotypes familiar in Western societies.

    2008-07-01

    We define and address the problem of finding the visual focus of attention for a varying number of wandering people (VFOA-W), determining where the people's movement is unconstrained. VFOA-W estimation is a new and important problem with mplications for behavior understanding and cognitive science, as well as real-world applications. One such application, which we present in this article, monitors the attention passers-by pay to an outdoor advertisement. Our approach to the VFOA-W problem proposes a multi-person tracking solution based on a dynamic Bayesian network that simultaneously infers the (variable) number of people in a scene, their body locations, their head locations, and their head pose. For efficient inference in the resulting large variable-dimensional state-space we propose a Reversible Jump Markov Chain Monte Carlo (RJMCMC) sampling scheme, as well as a novel global observation model which determines the number of people in the scene and localizes them. We propose a Gaussian Mixture Model (GMM) and Hidden Markov Model (HMM)-based VFOA-W model which use head pose and location information to determine people's focus state. Our models are evaluated for tracking performance and ability to recognize people looking at an outdoor advertisement, with results indicating good performance on sequences where a moderate number of people pass in front of an advertisement.

    This paper introduces a novel contextual model for the recognition of people's visual focus of attention (VFOA) in meetings from audio-visual perceptual cues. More specifically, instead of independently recognizing the VFOA of each meeting participant from his own head pose, we propose to jointly recognize the participants' visual attention in order to introduce context-dependent interaction models that relate to group activity and the social dynamics of communication. Meeting contextual information is represented by the location of people, conversational events identifying floor holding patterns, and a presentation activity variable. By modeling the interactions between the different contexts and their combined and sometimes contradictory impact on the gazing behavior, our model allows us to handle VFOA recognition in difficult task-based meetings involving artifacts, presentations, and moving people. We validated our model through rigorous evaluation on a publicly available and challenging data set of 12 real meetings (5 hours of data). The results demonstrated that the integration of the presentation and conversation dynamical context using our model can lead to significant performance improvements.

  15. Investigation of focused and unfocused transducer beam patterns in moderately nonlinear absorbing media

    2001-05-01

    The novel solution of the KZK equation for acoustic pressure of the second harmonic in slightly focused beam of a circular transducer was obtained in a closed form for moderately nonlinear absorbing media (Gol'dberg numbers ~ 1). The solution is based on the method of slowly changing wave profile in combination with the method of successive approximations. Two pairs of transducers (Valpey-Fisher Corp.) Were compared to investigate the influence of focusing on the applicability of the moderate nonlinearity approach. The first pair was of 0.25' diameter and the second was of 0.5' diameter. Both pairs has one transducer with flat surface and the other geometrically focused at 4'. The central frequency for all transducers was 5 MHz. Measurements were undertaken in the blood-mimicking solution of water and glycerine. The results demonstrated that for slightly focused transducers with circular apertures, the moderate nonlinearity approach is still valid, as it was proved for flat sources with the same source level, despite the higher pressures in the focal region. The peak pressure for the weakly focused system occurs at a shorter range than focal length.

    Full Text Available Most societies in Western World has formulated a premature assumptions toward Islam due to the negative depictions of Islamic world doing by Western media which focused mainly on the issues of terrorism, intolerance, poverty, conflicts, fanaticism, horrible disease, low life qualities among Islamic countries, backwardness and lack of progress. This article explores and describes some statements made by Western media (as well as Western journalists, along with events as the setting of such comments. In order to overcome such situations, media monitoring must be professional and constant. Those who concern with the misleading information toward Islam must provide clear, short, and well-written press releases at regular intervals. Another suggestion is by drawing attention of ethnic youth toward journalism as noble profession and good trade.

    Full Text Available The media products of the revolutionary movement known as the Islamic State (also IS, ISIL, ISIS, Daesh have received a significant amount of attention from analysts and journalists alike. While extremely helpful, most of this effort is focused at performing content analysis of fairly recent products. As part of the Counter-Terrorism Strategic Communication (CTSC project’s effort to better understand propaganda messaging in the 21st century, the author of this Research Paper examined primary documents and other media published by the Islamic State movement during its entire existence in order to develop a history of the media department since 2003. The framework for analysis focused on the interaction between key media leaders, the ever-expanding structure and institutions, and the process of innovation used to experiment with different media techniques in different phases of the group’s evolution. Based on this history, the paper presents six observations about the media department and its role in the larger movement – in the hopes that this knowledge will be helpful in efforts to combat this particular group and its inevitable imitators in the future.

    2017-12-01

    Full Text Available This thematic issue of Media and Communication focuses attention on the shift towards visual images on social media as well as the transformation of visual communication which has occurred within the online ecology of social media platforms. The sharing of images is becoming an integral part of the social media experience today, and given that social media platforms are the prime locus for sociability—at least among young people in the West—this shift towards visuals arguably transforms how we relate to each other and the world around us, as well as how we perceive and construct our sense of self. For researchers, this raises conceptual, theoretical and methodological challenges. This thematic issue presents six articles as well as a book review on visual communication in social media focusing on developing a conceptual apparatus and precise definitions of objects and practices of study as well as contributions that address and discuss the methodological challenges as well as their potential solutions. The idea was to synergize research from a wide variety of communication-related disciplines on this rather new topic.

    Modern social media are becoming overloaded with information because of the rapidly-expanding number of information feeds. We analyze the user-generated content in Sina Weibo, and find evidence that the spread of popular messages often follow a mechanism that differs from the spread of disease, in contrast to common belief. In this mechanism, an individual with more friends needs more repeated exposures to spread further the information. Moreover, our data suggest that for certain messages the chance of an individual to share the message is proportional to the fraction of its neighbours who shared it with him/her, which is a result of competition for attention. We model this process using a fractional susceptible infected recovered (FSIR) model, where the infection probability of a node is proportional to its fraction of infected neighbors. Our findings have dramatic implications for information contagion. For example, using the FSIR model we find that real-world social networks have a finite epidemic threshold in contrast to the zero threshold in disease epidemic models. This means that when individuals are overloaded with excess information feeds, the information either reaches out the population if it is above the critical epidemic threshold, or it would never be well received.

    2010-01-01

    Full Text Available This paper analyzes media and public discourses surrounding net neutrality, with particular attention to public utility philosophy, from a critical perspective. The article suggests that further public education about net neutrality would be beneficial. The first portion of this paper provides a survey of the existing literature surrounding net neutrality, highlighting the contentious debate between market-based and public interest perspectives. In order to contextualize the debate, an overview of public utility philosophy is provided, shedding light on how the Internet can be conceptualized as a public good. Following this discussion, an analysis of mainstream media is presented, exploring how the media represents the issue of net neutrality and whether or not the Internet is discussed through the lens of public utility. To further examine how the net neutrality debate is being addressed, and to see the potential impacts of media discourses on the general public, the results of a focus group are reported and analyzed. Finally, a discussion assesses the implications of the net neutrality debate as presented through media discourses, highlighting the future of net neutrality as an important policy issue.

    2018-06-01

    Based on cue reactivity theory, food cues embedded in media content can lead to physiological and psychological responses in children. Research suggests that unhealthy food cues are represented more extensively and interactively in children's media environments than healthy ones. However, it is not clear to this date whether children react differently to unhealthy compared to healthy food cues. In an experimental study with 56 children (55.4% girls; M age  = 8.00, SD = 1.58), we used eye-tracking to determine children's attention to unhealthy and healthy food cues embedded in a narrative cartoon movie. Besides varying the food type (i.e., healthy vs. unhealthy), we also manipulated the integration levels of food cues with characters (i.e., level of food integration; no interaction vs. handling vs. consumption), and we assessed children's individual susceptibility factors by measuring the impact of their hunger level. Our results indicated that unhealthy food cues attract children's visual attention to a larger extent than healthy cues. However, their initial visual interest did not differ between unhealthy and healthy food cues. Furthermore, an increase in the level of food integration led to an increase in visual attention. Our findings showed no moderating impact of hunger. We conclude that especially unhealthy food cues with an interactive connection trigger cue reactivity in children. Copyright © 2018 Elsevier Ltd.

  13. The Differential Effects of Attentional Focus in Children with Moderate and Profound Visual Impairments

    Scott W. T. McNamara

    2017-10-01

    Full Text Available It has been consistently reported that an external focus of attention leads to better motor performance than an internal focus, but no research to date has explored this effect in a population with visual impairments (VI. External focus statements typically reference something in the environment (e.g., target that may be difficult to conceptualize for people with VI since they cannot generate a visual representation of the object of focus. Internal focus statements could be more closely identifiable with proprioception that is not impaired in this population. Recent studies have reported that sighted adults with temporarily obstructed vision are able to receive an external focus benefit when performing discrete tasks (i.e., golf putt and vertical jump, however, it is unclear if those with VI would experience the same benefit. The purpose of this investigation was to compare how an internal focus and external focus impact the balance of children with VI. Eighteen children with VI were grouped into a moderate (n = 11 and a profound VI group (n = 7. Participants completed a familiarization trial, an internal focus trial (i.e., focusing on feet and an external focus trial (i.e., focusing on markers in a counterbalanced order. The moderate VI group had a lower root mean square error while using an external focus (p = 0.04, while the profound VI group did not differ between conditions (p > 0.05. These results suggest that while performing a task reliant on sensory feedback, an external focus benefit may be dependent on the severity of VI. Further research is needed to examine whether external focus statements can be presented in a way that may be more intuitive to those with profound VI. These findings may help to influence how professionals in health-related fields (e.g., physical therapist and physical educators give instructions on motor performance to populations with VI.

  14. Quantifying collective attention from tweet stream.

    Directory of Open Access Journals (Sweden)

    Kazutoshi Sasahara

    Full Text Available Online social media are increasingly facilitating our social interactions, thereby making available a massive "digital fossil" of human behavior. Discovering and quantifying distinct patterns using these data is important for studying social behavior, although the rapid time-variant nature and large volumes of these data make this task difficult and challenging. In this study, we focused on the emergence of "collective attention" on Twitter, a popular social networking service. We propose a simple method for detecting and measuring the collective attention evoked by various types of events. This method exploits the fact that tweeting activity exhibits a burst-like increase and an irregular oscillation when a particular real-world event occurs; otherwise, it follows regular circadian rhythms. The difference between regular and irregular states in the tweet stream was measured using the Jensen-Shannon divergence, which corresponds to the intensity of collective attention. We then associated irregular incidents with their corresponding events that attracted the attention and elicited responses from large numbers of people, based on the popularity and the enhancement of key terms in posted messages or "tweets." Next, we demonstrate the effectiveness of this method using a large dataset that contained approximately 490 million Japanese tweets by over 400,000 users, in which we identified 60 cases of collective attentions, including one related to the Tohoku-oki earthquake. "Retweet" networks were also investigated to understand collective attention in terms of social interactions. This simple method provides a retrospective summary of collective attention, thereby contributing to the fundamental understanding of social behavior in the digital era.

  16. The Effect of Enumeration of Self-Relevant Words on Self-Focused Attention and Repetitive Negative Thoughts

    2018-01-01

    Self-focused attention refers to awareness of self-referent, internally generated information. It can be categorized into dysfunctional (i.e., self-rumination) and functional (self-reflection) aspects. According to theory on cognitive resource limitations (e.g., Moreno, 2006), there is a difference in cognitive resource allocation between these two aspects of self-focused attention. We propose a new task, self-relevant word (SRW) enumeration, that can aid in behaviorally identifying individuals’ use of self-rumination and self-reflection. The present study has two purposes: to determine the association between self-focus and SRW enumeration, and to examine the effect of dysfunctional SRW enumeration on repetitive negative thinking. One hundred forty-six undergraduate students participated in this study. They completed a measure of state anxiety twice, before and after imagining a social failure situation. They also completed the SRW enumeration task, Repetitive Thinking Questionnaire, Short Fear of Negative Evaluation Scale, and Rumination-Reflection Questionnaire. A correlational analysis indicated a significant positive correlation between self-reflection and the number of SRWs. Furthermore, individuals high in self-reflection had a tendency to pay more attention to problems than did those high in self-rumination. A significant positive correlation was found between self-rumination and the strength of self-relevance of negative SRWs. Through a path analysis, we found a significant positive effect of the self-relevance of negative SRWs on repetitive negative thinking. Notably, however, the model that excluded self-rumination as an explanatory variable showed a better fit to the data than did the model that included it. In summary, SRW enumeration might enable selective and independent detection of the degree of self-reflection and self-rumination, and therefore should be examined in future research in order to design new behavioral procedures.

Through a path analysis, we found a significant positive effect of the self-relevance of negative SRWs on repetitive negative thinking. Notably, however, the model that excluded self-rumination as an explanatory variable showed a better fit to the data than did the model that included it. In summary, SRW enumeration might enable selective and independent detection of the degree of self-reflection and self-rumination, and therefore should be examined in future research in order to design new behavioral procedures.

    Reflex cough is a defensive response generated in the brainstem in response to chemical and mechanical stimulation of the airways. However, converging evidence shows that reflex cough is also influenced by central neural control processes. In this study, we investigate whether reflex cough can be modulated by attentional focus on either external stimuli or internal cough-related stimuli. Healthy volunteers (N = 24; seven men; age range, 18-25 years) completed four blocks of citric acid-induced cough challenges while, simultaneously, auditory stimuli were presented. Within each block, four concentrations were administered (30, 100, 300 and 1,000 mM, randomized). During two subsequent blocks, participants focused their attention externally (counting tones). During the other two blocks, participants focused their attention internally (counting coughs). The order of attentional focus was counterbalanced across participants. Ratings of the urge to cough were collected after each challenge. Cough frequency was determined by audio recording. Cough frequency was higher when participants focused their attention internally vs externally (P Reflex cough can be modulated by attentional focus. Internally focused attention may be a mechanism involved in excessive (idiopathic) cough, while an external focus may be introduced as part of treatments targeting excessive cough.

  19. Some Implications for Regulation of ICT and Media Convergence

    The term convergence in the areas of ICT and media means the coming together of IT, telecommunications, broadcasting and other media, technologically, market and policy wise. It is the sectoral convergence of the hitherto more separate ICT and media areas, which is in focus, even though...... there certainly are also changes taking place vertically in the different sectors. The paper examines the relationships between technology and market developments and policy and regulatory initiatives. The issue is, therefore, not solely the implications of market and technology trends on policy and regulation......, but also the reverse implications of policy and regulatory frameworks on technology and market developments. The paper analyses the convergence tendencies at a technological, market level and policy and regulatory level. It is, however, the policy level, which is the centre of attention in the paper...

    Factors such as an external focus of attention (EF) and augmented feedback (AF) have been shown to improve performance. However, the efficacy of providing AF to enhance motor performance has never been compared with the effects of an EF or an internal focus of attention (IF). Therefore, the aim of the present study was to identify which of the three conditions (AF, EF or IF) leads to the highest performance in a countermovement jump (CMJ). Nineteen volunteers performed 12 series of 8 maximum CMJs. Changes in jump height between conditions and within the series were analysed. Jump heights differed between conditions (P jump heights at the end of the series in AF (+1.60%) and lower jump heights at the end of the series in EF (-1.79%) and IF (-1.68%) were observed. Muscle activity did not differ between conditions. The differences between conditions and within the series provide evidence that AF leads to higher performance and better progression within one series than EF and IF. Consequently, AF seems to outperform EF and IF when maximising jump height.

    Attentional focus research suggests an external focus leads to improved motor performance compared to an internal focus (Wulf in Int Rev Sport Exerc Psychol 6:77-104, 2013), but skilled athletes often report using an internal focus (Fairbrother et al., Front Psychol 7:1028, 2016) and sometimes shifting between different foci in the preparation and execution phases of performance (Bernier et al. in J Appl Sport Psychol 23:326-341, 2011; Bernier et al. in Sport Psychol 30:256-266, 2016). To date, focus shifts have been unexplored in experimental research, thus the purpose of this study was to determine the effect of shifting focus between the preparation and execution phases of a standing long jump. Participants (N = 29) completed two jumps in a control condition (CON), followed by two jumps in four experimental conditions presented in a counterbalanced order. Conditions included using an external focus (EF) and internal focus (IF) in both preparation and execution of the skill, as well as shifting from an internal focus in preparation to an external focus in execution (ITE), and an external focus in preparation to an internal focus in execution (ETI). Jump distance was analyzed with a repeated measures ANOVA. The main effect of condition was significant, p ITE also generated farther jumps than IF and CON (p's ITE conditions suggests that the focus employed in execution has the strongest impact on performance. Additionally, if an internal focus must be used in preparation, the performance decrement can be ameliorated by shifting to an external focus during execution.

    For children of school age television is still the dominant medium. TV consumption isn't only limited on the TV set, but also happens on the computer with internet access and mobile devices. Computer games take a high priority for boys. For girls reading is still an important experience space. Parents influence the media use of their children by their role model, and the rates for shared non-media experiences. Neighborhoods which aren't child-friendly can cause children's withdraw into home media spaces. Restrictions and controls are less important than the conversations that are conducted around media interests of the child and parents attention to early signs of problematic media use. Potentially irritating media content for children (such as violence or sex) can have strong effects when there's no open debate taking place in the family around these issues. Today's media diversity leads to parallel surfing and multi-tasking. In order that this doesn't influence children's cognitive development and learning negatively a culture of regular restriction to one activity, to which they devote their full attention, is required.

  3. Ethical issues when using social media for health outside professional relationships.

    2015-04-01

    Social media have the potential to revolutionize health and healthcare, but fulfilling this potential requires attention to the ethical issues social media may raise. This article reviews the major ethical issues arising when social media are used for research, public health, mobile health applications, and global health. It focuses on social media use outside fiduciary relationships between healthcare professionals and patients. Emphasis is given to the potential of social media in these contexts, the ethical issues relatively unique to each, and where possible how existing ethical principles and frameworks could help navigate these issues. In some cases social media create the circumstance for particular ethical issues but also facilitate managing them, such as in informed consent for research. In other cases, disagreement exists about whether social media - despite their potential - should be used for certain purposes, such as in public health surveillance (where confidentiality represents a significant ethical concern). In still others, ethical uncertainty exists about how social media will affect ethical issues, such as inequality in global health. As social media technologies continue to develop, identifying and managing the ethical issues they raise will be critical to their success in improving health while preserving fundamental ethical values.

    Stress-related disorders, e.g., anxiety and depression, are characterized by decreased top-down control for distracting information, as well as a memory bias for threatening information. However, it is unclear how acute stress biases mnemonic encoding and leads to prioritized storage of threat-related information even if outside the focus of attention. In the current study, healthy adults (N = 53, all male) were randomly assigned to stress induction using the socially evaluated cold-pressor test (SECPT) or a control condition. Participants performed a task in which they were required to identify a target letter within a string of letters that were either identical to the target and thereby facilitating detection (low distractor load) or mixed with other letters to complicate the search (high load). Either a fearful or neutral face was presented on the background, outside the focus of attention. Twenty-four hours later, participants were asked to perform a surprise recognition memory test for those background faces. Stress induction resulted in increased cortisol and negative subjective mood ratings. Stress did not affect visual search performance, however, participants in the stress group showed stronger memory compared to the control group for fearful faces in the low attentional load condition. Critically, the stress induced memory bias was accompanied by decoupling between amygdala and DLFPC during encoding, which may represent a mechanism for decreased ability to filter task-irrelevant threatening background information. The current study provides a potential neural account for how stress can produce a negative memory bias for threatening information even if presented outside the focus of attention. Despite of an adaptive advantage for survival, such tendencies may ultimately also lead to generalized fear, a possibility requiring additional investigation. Copyright © 2018.

  7. Oculomotor examination of the weapon focus effect: does a gun automatically engage visual attention?

    Flowe, Heather D; Hope, Lorraine; Hillstrom, Anne P

    2013-01-01

    A person is less likely to be accurately remembered if they appear in a visual scene with a gun, a result that has been termed the weapon focus effect (WFE). Explanations of the WFE argue that weapons engage attention because they are unusual and/or threatening, which causes encoding deficits for the other items in the visual scene. Previous WFE research has always embedded the weapon and nonweapon objects within a larger context that provides information about an actor's intention to use the object. As such, it is currently unknown whether a gun automatically engages attention to a greater extent than other objects independent of the context in which it is presented. Reflexive responding to a gun compared to other objects was examined in two experiments. Experiment 1 employed a prosaccade gap-overlap paradigm, whereby participants looked toward a peripheral target, and Experiment 2 employed an antisaccade gap-overlap paradigm, whereby participants looked away from a peripheral target. In both experiments, the peripheral target was a gun or a nonthreatening object (i.e., a tomato or pocket watch). We also controlled how unexpected the targets were and compared saccadic reaction times across types of objects. A gun was not found to differentially engage attention compared to the unexpected object (i.e., a pocket watch). Some evidence was found (Experiment 2) that both the gun and the unexpected object engaged attention to a greater extent compared the expected object (i.e., a tomato). An image of a gun did not engage attention to a larger extent than images of other types of objects (i.e., a pocket watch or tomato). The results suggest that context may be an important determinant of WFE. The extent to which an object is threatening may depend on the larger context in which it is presented.

  9. The Focus of Spatial Attention Determines the Number and Precision of Face Representations in Working Memory.

    Science.gov (United States)

    Towler, John; Kelly, Maria; Eimer, Martin

    2016-06-01

    The capacity of visual working memory for faces is extremely limited, but the reasons for these limitations remain unknown. We employed event-related brain potential measures to demonstrate that individual faces have to be focally attended in order to be maintained in working memory, and that attention is allocated to only a single face at a time. When 2 faces have to be memorized simultaneously in a face identity-matching task, the focus of spatial attention during encoding predicts which of these faces can be successfully maintained in working memory and matched to a subsequent test face. We also show that memory representations of attended faces are maintained in a position-dependent fashion. These findings demonstrate that the limited capacity of face memory is directly linked to capacity limits of spatial attention during the encoding and maintenance of individual face representations. We suggest that the capacity and distribution of selective spatial attention is a dynamic resource that constrains the capacity and fidelity of working memory for faces. © The Author 2015.

    Objective. Conventional, multi-channel scalp electroencephalography (EEG) allows the identification of the attended speaker in concurrent-listening (‘cocktail party’) scenarios. This implies that EEG might provide valuable information to complement hearing aids with some form of EEG and to install a level of neuro-feedback. Approach. To investigate whether a listener’s attentional focus can be detected from single-channel hearing-aid-compatible EEG configurations, we recorded EEG from three electrodes inside the ear canal (‘in-Ear-EEG’) and additionally from 64 electrodes on the scalp. In two different, concurrent listening tasks, participants (n  =  7) were fitted with individualized in-Ear-EEG pieces and were either asked to attend to one of two dichotically-presented, concurrent tone streams or to one of two diotically-presented, concurrent audiobooks. A forward encoding model was trained to predict the EEG response at single EEG channels. Main results. Each individual participants’ attentional focus could be detected from single-channel EEG response recorded from short-distance configurations consisting only of a single in-Ear-EEG electrode and an adjacent scalp-EEG electrode. The differences in neural responses to attended and ignored stimuli were consistent in morphology (i.e. polarity and latency of components) across subjects. Significance. In sum, our findings show that the EEG response from a single-channel, hearing-aid-compatible configuration provides valuable information to identify a listener’s focus of attention.

    The advent of social media has led to the ability for individuals all over the world to communicate with each other, in real time, about mutual topics of interest in an unprecedented manner. Recently, the use of social media has increased among people interested in healthcare and medical research, particularly in the field of hematology and oncology, a field which frequently experiences rapid shifts of information and novel, practice-changing discoveries. Among the many social media platforms available to cancer patients and providers, one platform in particular, Twitter, has become the focus for the creation of disease-specific communities, especially for those interested in, affected by, or those who perform research in the fields of rare cancers, which historically have had a dearth of reliable information available. This article will focus on the initiation and progress of one such Twitter hematology/oncology community, #mpnsm, which was originally created for the purpose of serving as a venue for improving the interaction among patients, providers, researchers, and organizations with interest in the myeloproliferative neoplasms (MPNs) and to further the availability of reliable up-to-date analysis; relevant expert commentary; and readily usable information for patients, providers, and other groups interested in this field.

    Amishi P Jha

    Full Text Available We investigated the impact of mindfulness training (MT on attentional performance lapses associated with task-unrelated thought (i.e., mind wandering. Periods of persistent and intensive demands may compromise attention and increase off-task thinking. Here, we investigated if MT may mitigate these deleterious effects and promote cognitive resilience in military cohorts enduring a high-demand interval of predeployment training. To better understand which aspects of MT programs are most beneficial, three military cohorts were examined. Two of the three groups were provided MT. One group received an 8-hour, 8-week variant of Mindfulness-based Mind Fitness Training (MMFT emphasizing engagement in training exercises (training-focused MT, n = 40, a second group received a didactic-focused variant emphasizing content regarding stress and resilience (didactic-focused MT, n = 40, and the third group served as a no-training control (NTC, n = 24. Sustained Attention to Response Task (SART performance was indexed in all military groups and a no-training civilian group (CIV, n = 45 before (T1 and after (T2 the MT course period. Attentional performance (measured by A', a sensitivity index was lower in NTC vs. CIV at T2, suggesting that performance suffers after enduring a high-demand predeployment interval relative to a similar time period of civilian life. Yet, there were significantly fewer performance lapses in the military cohorts receiving MT relative to NTC, with training-focused MT outperforming didactic-focused MT at T2. From T1 to T2, A' degraded in NTC and didactic-focused MT but remained stable in training-focused MT and CIV. In sum, while protracted periods of high-demand military training may increase attentional performance lapses, practice-focused MT programs akin to training-focused MT may bolster attentional performance more than didactic-focused programs. As such, training-focused MT programs should be further examined in cohorts

    Media literacy intervention efficacy literature has focused on media-relevant (e.g., knowledge and realism) and behavior-relevant outcomes (e.g., attitudes and behaviors), without much attention paid to interpersonal communication outcomes. This project examined interpersonal communication after participation in two versions (analysis plus analysis and analysis plus planning) of the Youth Message Development (YMD) intervention, a brief media literacy curriculum targeted at preventing high school student alcohol use. Participants attended a 75-mins media literacy YMD workshop and completed a delayed posttest questionnaire 3 to 4 months later. Overall, 68 % participants replied affirmatively to interpersonal communication about the YMD intervention. Communication about the workshop moderated the effects of the type of workshop (analysis plus analysis or analysis plus planning) on self-efficacy to counter-argue (but not critical thinking). Interpersonal communication moderated the effects of the YMD intervention on self-efficacy to counter-argue, thereby signaling the importance of including interpersonal communication behaviors in intervention evaluation.

    Social media is increasingly being adopted in health discourse. We examine the role played by identity in supporting discourse on socially stigmatized conditions. Specifically, we focus on mental health communities on reddit. We investigate the characteristics of mental health discourse manifested through reddit's characteristic 'throwaway' accounts, which are used as proxies of anonymity. For the purpose, we propose affective, cognitive, social, and linguistic style measures, drawing from literature in psychology. We observe that mental health discourse from throwaways is considerably disinhibiting and exhibits increased negativity, cognitive bias and self-attentional focus, and lowered self-esteem. Throwaways also seem to be six times more prevalent as an identity choice on mental health forums, compared to other reddit communities. We discuss the implications of our work in guiding mental health interventions, and in the design of online communities that can better cater to the needs of vulnerable populations. We conclude with thoughts on the role of identity manifestation on social media in behavioral therapy.

    Full Text Available Facebook posts, YouTube videos, tweets and wooing political bloggers have become standard practice in marketing political campaigns. Research has demonstrated the effect of new media on a host of politically-related behavior, including political participation, knowledge acquisition, group formation and self-efficacy. Yet, issues related to media trust, media performance and candidate evaluations have not been fully explored. In addition, much of the political marketing research looks exclusively at the Millennial age cohort, ignoring other age groups, particularly Baby Boomers. This case study addresses whether attention to traditional (i.e., television, hard-copy newspapers and radio and online media sources (i.e., political candidate websites, television network websites, online newspapers, Facebook, Twitter, YouTube, Tumblr and political blogs about the 2012 U.S. presidential campaign influences Millennials and Baby Boomers’ media trust and performance ratings, as well as candidate evaluations. Panel surveys were completed by both age cohorts, Millennials (n = 431 and Baby Boomers (n = 360, during the last two weeks of the presidential election. Findings indicate that traditional sources, specifically television, rather than online sources are significantly linked to media trust and performance ratings among both Boomers and Millennials. Attention to traditional media for campaign information predicts Boomers’ candidate evaluations, whereas Millennials’ candidate evaluations are influenced by online sources, such as Facebook and candidate websites.

  4. Does Media Multitasking Always Hurt?

    2011-05-01

    Full Text Available Chronic heavy media multitaskers have been found impaired cognitive performance on certain cognitive tasks (Ophir, Nass & Wagner, 2009. However, the poor performance may be caused by their breadth-biased style of cognitive control rather than a deficit in cognitive abilities such as the ability to filter out interference from irrelevant stimuli and representations in memory. In this study, a new media multitasking index was invented to differentiate heavy and light media multitaskers by adding three open ended questions to the Media Use Questionnaire used by Ophir, Nass and Wagner (2009. Also, four different cognitive tasks, which access the ability of attentional capture, attention allocation to infrequent information, task switching and crossmodal integration, were used to investigate whether the poor performance of heavy media multitaskers is general to a wider range of tasks. Preliminary results found that heavy media multitaskers showed better improvement in accuracy between the sound present condition and sound absent condition of Pip and Pop Task (Van der Burg, Olivers, Bronkhorst, & theeuwes, 2008. Heavy media multitaskers appeared to have better ability of crossmodal integration than light medie multitaskers; hence, their poor performance is limited in only certain cognitive tasks.

  6. Evidence inhibition responds reactively to the salience of distracting information during focused attention.

    Directory of Open Access Journals (Sweden)

    Natalie Wyatt

    Full Text Available Along with target amplification, distractor inhibition is regarded as a major contributor to selective attention. Some theories suggest that the strength of inhibitory processing is proportional to the salience of the distractor (i.e., inhibition reacts to the distractor intensity. Other theories suggest that the strength of inhibitory processing does not depend on the salience of the distractor (i.e., inhibition does not react to the distractor intensity. The present study aimed to elucidate the relationship between the intensity of a distractor and its subsequent inhibition during focused attention. A flanker task with a variable distractor-target stimulus-onset asynchrony (SOA was used to measure both distractor interference and distractor inhibition. We manipulated the intensity of the distractor in two separate ways, by varying its distance from the target (Experiment 1 and by varying its brightness (Experiment 2. The results indicate that more intense distractors were associated with both increased interference and stronger distractor inhibition. The latter outcome provides novel support for the reactive inhibition hypothesis, which posits that inhibition reacts to the strength of distractor input, such that more salient distractors elicit stronger inhibition.

    It may be possible to use attention-based exercise to decrease demands associated with walking in Parkinson's disease (PD), and thus improve dual task walking ability. For example, an external focus of attention (focusing on the effect of an action on the environment) may recruit automatic control processes degenerated in PD, whereas an internal focus (limb movement) may recruit conscious (nonautomatic) control processes. Thus, we aimed to investigate how externally and internally focused exercise influences dual task walking and symptom severity in PD. Forty-seven participants with PD were randomized to either an Externally (n = 24) or Internally (n = 23) focused group and completed 33 one-hour attention-based exercise sessions over 11 weeks. In addition, 16 participants were part of a control group. Before, after, and 8 weeks following the program (pre/post/washout), gait patterns were measured during single and dual task walking (digit-monitoring task, ie, walking while counting numbers announced by an audio-track), and symptom severity (UPDRS-III) was assessed ON and OFF dopamine replacement. Pairwise comparisons (95% confidence intervals [CIs]) and repeated-measures analyses of variance were conducted. Pre to post: Dual task step time decreased in the external group (Δ = 0.02 seconds, CI 0.01-0.04). Dual task step length (Δ = 2.3 cm, CI 0.86-3.75) and velocity (Δ = 4.5 cm/s, CI 0.59-8.48) decreased (became worse) in the internal group. UPDRS-III scores (ON and OFF) decreased (improved) in only the External group. Pre to washout: Dual task step time ( P = .005) and percentage in double support ( P = .014) significantly decreased (improved) in both exercise groups, although only the internal group increased error on the secondary counting task (ie, more errors monitoring numbers). UPDRS-III scores in both exercise groups significantly decreased ( P = .001). Since dual task walking improvements were found immediately, and 8 weeks after the cessation of an

    Full Text Available Non-intrusive experimentation and measurements can be obtained from the latest neuroscience scanning techniques and technologies. Such technologies are now quite affordable and could possibly be used for the reading process research in information and communication sciences. The research experiment focuses on measuring the changes in attention while reading the text on different media (devices. The pilot experiment showed that cheap and easy to use brainwave measuring devices can be used for testing reading processes by measuring attention (concentration. The results revealed that a reading medium (device affects the level of attention and suggested that less attention is needed to read from paper compared to any size or type of screen. Reading books (in a foreign language can mostly be considered neutral on the attention level scale (slightly shifted towards 53 on a 1-100 scale.

    The ability to develop and distribute digital teaching resources in higher education has developed rapidly over the last decade but research into how students use such resources has received limited attention. This study uses questionnaire results, Internet analytic data and semi-structured interviews to examine the use of three types of rich-media teaching resources - lecture podcasts, key-concept videos and tutorial solution videos - by engineering undergraduates. It is found that students value all three types of resource, especially for revision and as a supplement to lectures. Students find short, focused resources more useful than longer ones. Non-native English speakers and those with disabilities derive particular benefits from the resources. The effect of rich-media resources on lecture attendance is found to be small, and two-way.

  10. Stereotypes in media and media literacy among young people

    Full Text Available Young people, the most common consumers of media content, bear out the view that media shapes people’s lives. Therefore we must not underestimate the effect media exerts on young people’s values and behavioral patterns. Television is the medium which draws children and young people for the greatest part of their free time. Regardless whether television programs are described as positive or negative, whether they abound with stereotypes or not, it is important that young people develop a critical attitude towards them so that they may resist different forms of media manipulation. The paper discusses how stereotypes are generated and used by media and the manners in which stereotypical concepts affect young people’s attitudes. It highlights the importance of the development of media literacy which implies a critical attitude towards media images and discourses, the development of criteria for the selection and evaluation of information broadcast by media, the development of skills in interpreting and understanding stereotypical concepts and familiarity with alternative forms of media culture. The paper draws special attention to the issue of media education. The conclusion is that schools should offer media literacy as part of their curriculum and in it possible solutions to the problems discussed. .

    To compare the long-term effects of external focus (EF) and internal focus (IF) of attention after 4 weeks of arm training. Randomized, repeated-measures, mixed analysis of variance. Outpatient clinic. Individuals with stroke and moderate-to-severe arm impairment living in the community (N=33; withdrawals: n=3). Four-week arm training protocol on a robotic device (12 sessions). Joint independence, Fugl-Meyer Assessment, and Wolf Motor Function Test measured at baseline, discharge, and 4-week follow-up. There were no between-group effects for attentional focus. Participants in both groups improved significantly on all outcome measures from baseline to discharge and maintained those changes at 4-week follow-up regardless of group assignment (joint independence EF condition: F 1.6,45.4 =17.74; P<.0005; partial η 2 =.39; joint independence IF condition: F 2,56 =18.66; P<.0005; partial η 2 =.40; Fugl-Meyer Assessment: F 2,56 =27.83; P<.0005; partial η 2 =.50; Wolf Motor Function Test: F 2,56 =14.05; P<.0005; partial η 2 =.35). There were no differences in retention of motor skills between EF and IF participants 4 weeks after arm training, suggesting that individuals with moderate-to-severe arm impairment may not experience the advantages of an EF found in healthy individuals. Attentional focus is most likely not an active ingredient for retention of trained motor skills for individuals with moderate-to-severe arm impairment, whereas dosage and intensity of practice appear to be pivotal. Future studies should investigate the long-term effects of attentional focus for individuals with mild arm impairment. Copyright © 2017 American Congress of Rehabilitation Medicine.

    Full Text Available Artificial vision systems cannot process all the information that they receive from the world in real time because it is highly expensive and inefficient in terms of computational cost. Inspired by biological perception systems, articial attention models pursuit to select only the relevant part of the scene. Besides, it is well established that the units of attention on human vision are not merely spatial but closely related to perceptual objects (proto-objects. This implies a strong bidirectional relationship between segmentation and attention processes. Therefore, while the segmentation process is the responsible to extract the proto-objects from the scene, attention can guide segmentation, arising the concept of foveal attention. When the focus of attention is deployed from one visual unit to another, the rest of the scene is perceived but at a lower resolution that the focused object. The result is a multi-resolution visual perception in which the fovea, a dimple on the central retina, provides the highest resolution vision. In this paper, a bottom-up foveal attention model is presented. In this model the input image is a foveal image represented using a Cartesian Foveal Geometry (CFG, which encodes the field of view of the sensor as a fovea (placed in the focus of attention surrounded by a set of concentric rings with decreasing resolution. Then multirresolution perceptual segmentation is performed by building a foveal polygon using the Bounded Irregular Pyramid (BIP. Bottom-up attention is enclosed in the same structure, allowing to set the fovea over the most salient image proto-object. Saliency is computed as a linear combination of multiple low level features such us colour and intensity contrast, symmetry, orientation and roundness. Obtained results from natural images show that the performance of the combination of hierarchical foveal segmentation and saliency estimation is good in terms of accuracy and speed.

    The neural substrate for clinical symptoms and neuropsychological performance in individuals with attention-deficit/hyperactivity disorder (ADHD) has rarely been studied and has yielded inconsistent results. We sought to compare the microstructural property of fibre tracts associated with the prefrontal cortex and its association with ADHD symptoms and a wide range of attention performance in youth with ADHD and healthy controls. We assessed youths with ADHD and age-, sex-, handedness-, coil- and intelligence-matched controls using the Conners' Continuous Performance Test (CCPT) for attention performance and MRI. The 10 target tracts, including the bilateral frontostriatal tracts (caudate to dorsolateral prefrontal cortex, ventrolateral prefrontal cortex and orbitofrontal cortex), superior longitudinal fasciculus (SLF) and cingulum bundle were reconstructed using diffusion spectrum imaging tractography. We computed generalized fractional anisotropy (GFA) values to indicate tract-specific microstructural property. We included 50 youths with ADHD and 50 healthy controls in our study. Youths with ADHD had lower GFA in the left frontostriatal tracts, bilateral SLF and right cingulum bundle and performed worse in the CCPT than controls. Furthermore, alteration of the right SLF GFA was most significantly associated with the clinical symptom of inattention in youths with ADHD. Finally, youths with ADHD had differential association patterns of the 10 fibre tract GFA values with attention performance compared with controls. Ten of the youths with ADHD were treated with methylphenidate, which may have long-term effects on microstructural property. Our study highlights the importance of the SLF, cingulum bundle and frontostriatal tracts for clinical symptoms and attention performance in youths with ADHD and demonstrates the involvement of different fibre tracts in attention performance in these individuals.

    Meditation Breath Attention Scores (MBAS) represent a self-report, state measure of focused attention (FA) during the practice of meditation. The MBAS assessment procedure involves sounding a bell at periodic intervals during meditation practice, at which times participants indicate if they were attending toward breathing (scored 1) or if instead they had become distracted (e.g., by mind wandering; scored 0); scores are then tallied to yield participants' MBAS for that meditation. The current study developed and evaluated a fully automated and Internet-based version of MBAS in 1,101 volunteers. Results suggested that: (a) MBAS are internally consistent across bell rings; (b) MBAS total scores exhibit a non-normal distribution identifying subgroups of participants with particularly poor or robust FA during meditation; (c) MBAS decrease linearly with the duration of meditation practices, indicating that participants tend to experience less FA later as opposed to earlier in the meditation; (d) in the case of eyes-open meditation, MBAS are higher when the amount of time between bells is shorter; (e) MBAS correlate with various self-reported subjective experiences occurring during meditation; and (f) MBAS are weakly associated with higher trait mindful "acting with awareness," lesser ADHD-related symptoms of inattentiveness, and estimated minutes of meditation practiced in the past month. In sum, results provide further support for the construct validity of MBAS and serve to further characterize the dynamics of individual differences in FA during meditation.

    2015-10-05

    A great amount of attention and consideration is being directed at possible applications of social media in many challenging areas. The use of social media has already shown its importance in the area of disaster response, where, each citizen is essentially acting as a sensor in reporting local conditions. In the aggregate, valuable information is obtained to enable a more effective response as well as provide timely information to those in the disaster area. No one needs to be trained to understand what constitutes a disaster, so a social media data stream from the public is literally always active and ready to engage. A similar but more focused approach is the use of crowdsourcing for science, where specific challenges in areas such as mathematics, astronomy, and biology are posted to social media and solved by the crowd.

    To explore how the results from the 2014 dual antiplatelet therapy (DAPT) trial were disseminated to the scientific community and online media. A a systematic review of scholarly and public attention surrounding the DAPT study. Data were collected from the ISI Web of Knowledge, Google Scholar, PubMed Commons, EurekAlert, the DAPT study website (www.daptstudy.org) and the New England Journal of Medicine website (for scholarly attention) and Altmetric Explorer, Snap Bird, YouTube (for public attention) citing DAPT study results appearing from 16 November 2014 to 10 June 2015. No participants were involved in this study. Proportion of contents highlighting the increased risk of mortality and critical to the author's interpretation of the results. We identified 425 items reported by seven sources; 164 (39%) disseminated the authors' interpretation via an electronic link or a reference, with no additional text. Among 81 items (19 %), the message favoured prolonged treatment and consequently overstated the article conclusions. Among 119 items (28 %), the text was uncertain about the benefit of prolonged treatment but was reported with no or inappropriate mention of increased risk of mortality. Only 34 items (8 %) were uncertain about the benefit of prolonged treatment and mentioned increased risk of mortality. In all, 27 items (6 %) did not favour prolonged treatment, and only 12 of these (3 %) clearly raised some concerns about the reporting of increased risk of death. Dissemination of the DAPT study results to the scientific community and on different media sources rarely criticised the interpretation of the study results. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

  18. Strategic perspective: Nuclear issues in the New Zealand media

    1992-01-01

    New Zealand's anti-nuclear policy drew international attention and threw the nation into a foreign policy crisis with the United States over the trilateral mutual security pact ANZUS. After more than a year of diminished intelligence and military cooperation, New Zealand was expelled from the alliance. This study involved a content analysis of coverage of these events and other nuclear issues in selected newspapers of New Zealand and the United States. Research points to the roles of the media as a critical one in the overall relations among countries. Through their frequent use of official government sources, the media tend to uphold the government line or status quo with regard to foreign affairs. This study sought to identify the nuclear issues covered in the New Zealand and US media, the characteristics of that coverage, the sources of that coverage and how coverage varied during changing US-New Zealand relations. The official frame prevailed in coverage of nuclear issues. In the New Zealand and US newspapers under study, most sources of nuclear issue news were government officials. This research also found that most coverage of nuclear issues in the New Zealand media was related to some aspect of US interests, and that coverage of New Zealand's policy in the US media was covered most often when related to the United States. Nuclear issue coverage was most often not crisis-oriented in New Zealand and US newspapers, but coverage of all nuclear issues increased dramatically during the period of the ANZUS policy crisis. This study found a number of changes in nuclear issue coverage in the New Zealand media after the policy crisis was resolved. Among those changes were a tendency to focus less on economic and trade effects of the anti-nuclear policy, a tendency to focus more on ties with other South Pacific nations, use more sources from those countries, and a tendency to focus less on the moral and ethical position of the country

  19. The media politics of oil spills

    International Nuclear Information System (INIS)

    Anderson, A.G.

    2002-01-01

    This paper considers the ways in which news values shape the reporting of oil spills and the constraints under which media practitioners work. A series of oil spills since the late 1960s [including the Torrey Canyon (1967), the Exxon Valdez (1989), and the Sea Empress (1996)] have attracted considerable attention from the news media. The focus is upon the dynamics through which news sources, with their own particular vested interests, compete to secure representation of the issues. Media discourse on risk and the environment is, to a significant extent, a discourse dependent upon the voices of official ''experts''. Environmental organizations, industry, scientists and government offer their own particular competing accounts of the ''reality'' of the situation. Issues concerning differential access to the news media are crucial when considering who comes to define the event. Accordingly, the article examines the strategies adopted by the various news sources involved in influencing the symbolic representation of public issues. Media practitioners are faced with great problems in interpreting and explaining these competing claims. Relatively few journalists and broadcasters have a scientific training and perhaps one of the greatest problems is that by simplifying complex scientific information one inevitably distorts it. Frequently researchers make the assumption that it is possible to demonstrate a direct causal link between news media coverage and public attitudes. However, the paper calls for great caution in interpreting ''public opinion'' concerning environmental issues and concludes by arguing that news media representations may more usefully be viewed as the outcome of a battle among a selective range of news sources, each seeking to provide their own definition of the public representation of the issues.

    The present study examined the impact of asthma-specific thought intrusion (TI) and thought suppression (TS) on two cognitive-affective variables (self-focused attention and fear of negative evaluation) among adolescents and young adults (AYAs) diagnosed with childhood-onset asthma. Participants were 290 AYAs who completed assessment questionnaires and participated in a written exercise electronically. Asthma-TI and TS were reported by participants following participation in a writing assignment. Asthma-TI was associated with increased private, public, and social anxiety self-focused attention, and greater fear of negative evaluation. Interestingly, asthma-TS was not associated with these same outcome variables. Findings suggest illness-specific cognitions are associated with cognitive-affective variables and it may be important to assess for illness-specific intrusive thoughts following asthma-focused medical appointments. Additionally, findings suggest the importance of assessing asthma-TI and TS separately in order to better understand thoughts about health and psychological functioning.

  1. Media multitasking and memory: Differences in working memory and long-term memory.

    Increasing access to media in the 21st century has led to a rapid rise in the prevalence of media multitasking (simultaneous use of multiple media streams). Such behavior is associated with various cognitive differences, such as difficulty filtering distracting information and increased trait impulsivity. Given the rise in media multitasking by children, adolescents, and adults, a full understanding of the cognitive profile of media multitaskers is imperative. Here we investigated the relationship between chronic media multitasking and working memory (WM) and long-term memory (LTM) performance. Four key findings are reported (1) heavy media multitaskers (HMMs) exhibited lower WM performance, regardless of whether external distraction was present or absent; (2) lower performance on multiple WM tasks predicted lower LTM performance; (3) media multitasking-related differences in memory reflected differences in discriminability rather than decision bias; and (4) attentional impulsivity correlated with media multitasking behavior and reduced WM performance. These findings suggest that chronic media multitasking is associated with a wider attentional scope/higher attentional impulsivity, which may allow goal-irrelevant information to compete with goal-relevant information. As a consequence, heavy media multitaskers are able to hold fewer or less precise goal-relevant representations in WM. HMMs' wider attentional scope, combined with their diminished WM performance, propagates forward to yield lower LTM performance. As such, chronic media multitasking is associated with a reduced ability to draw on the past--be it very recent or more remote--to inform present behavior.

    Full Text Available Security and entertainment are moving closer together. The term Securitainment expresses in this context, the mediation of security through entertainment formats. This will open a new space for Internal Security, which includes its own actors and patterns of interpretation. This space is portrayed in the media and follows the logic of media for attention but is also part of the process of social control. The mass media are therefore an instance of the design of internal security, social control and an interpretation producer. Mass media become actors of the internal security. They provide a symbolic representation of security.

    High-resolution imaging through turbid media is a fundamental challenge of optical sciences that has attracted a lot of attention in recent years for its wide range of potential applications. Here, we demonstrate that the resolution of imaging systems looking behind a highly scattering medium can be improved below the diffraction-limit. To achieve this, we demonstrate a novel microscopy technique enabled by the optical memory effect that uses a deconvolution image processing and thus it does not require iterative focusing, scanning or phase retrieval procedures. We show that this newly established ability of direct imaging through turbid media provides fundamental and practical advantages such as three-dimensional refocusing and unambiguous object reconstruction.

    The increasing prominence of the Internet in everyday life has prompted methodological innovations in qualitative research, particularly the adaptation of established methods of data collection for use online. The alternative online context brings with it both opportunities and challenges. To date the literature on online focus groups has focused mainly on the suitability of the method for qualitative data collection, and the development of approaches to facilitation that maximise interaction. By reflecting on our experiences of designing and attempting to recruit participants to online focus groups for two exploratory research projects, we aim to contribute some novel reflections around the less articulated issues of sampling and recruitment for online focus groups. In particular, we highlight potentially problematic issues around offline recruitment for an online method of data collection; the potential of using social media for recruitment; and the uncertainties around offering incentives in online recruitment, issues which have received little attention in the growing literature around online focus groups. More broadly, we recommend continued examination of online social practices and the social media environment to develop appropriate and timely online recruitment strategies and suggest further areas for future research and innovation.

    The recent use of social media by protesters in Iran, Egypt, Yemen and elsewhere has focused new attention on this communications medium. Government agencies and businesses, as well, are using social media to push information to their stakeholders. Those who are on the front lines of this information revolution, however, realise that social media is most effective when the communication is two-way. Unlike other media, social media allows information sharing. This, in turn, provides emergency managers with new situational-awareness resources when trying to mitigate an incident. As Federal Emergency Management Agency (FEMA) Administrator Craig Fugate told Information Week on January 19th, 2011: 'We can adjust much quicker if we can figure out how to have (a) two-way conversation and if we can look at the public as a resource. The public is putting out better situational awareness than many of our own agencies can.' This paper provides examples of how social media can be used as a situational-awareness resource and specific 'tools' that can be used to assist with this task.

  14. Using frequency tagging to quantify attentional deployment in a visual divided attention task.

    Toffanin, Paolo; de Jong, Ritske; Johnson, Addie; Martens, Sander

    2009-06-01

    Frequency tagging is an EEG method based on the quantification of the steady state visual evoked potential (SSVEP) elicited from stimuli which flicker with a distinctive frequency. Because the amplitude of the SSVEP is modulated by attention such that attended stimuli elicit higher SSVEP amplitudes than do ignored stimuli, the method has been used to investigate the neural mechanisms of spatial attention. However, up to now it has not been shown whether the amplitude of the SSVEP is sensitive to gradations of attention and there has been debate about whether attention effects on the SSVEP are dependent on the tagging frequency used. We thus compared attention effects on SSVEP across three attention conditions-focused, divided, and ignored-with six different tagging frequencies. Participants performed a visual detection task (respond to the digit 5 embedded in a stream of characters). Two stimulus streams, one to the left and one to the right of fixation, were displayed simultaneously, each with a background grey square whose hue was sine-modulated with one of the six tagging frequencies. At the beginning of each trial a cue indicated whether targets on the left, right, or both sides should be responded to. Accuracy was higher in the focused- than in the divided-attention condition. SSVEP amplitudes were greatest in the focused-attention condition, intermediate in the divided-attention condition, and smallest in the ignored-attention condition. The effect of attention on SSVEP amplitude did not depend on the tagging frequency used. Frequency tagging appears to be a flexible technique for studying attention.

    We investigated the role of self-focused attention (SFA) in social anxiety (disorder) in an ecologically valid way. In Experiment 1 high (n = 26) versus low (n = 25) socially anxious single women between 18 and 30 years had a video ("Skype") conversation with an attractive male confederate, while seeing themselves and the confederate on-screen. The conversation was divided in four phases: (I) warm-up, (II) positive (confederate was friendly to the participant), (III) critical (confederate was critical to the participant), and (IV) active (participant was instructed to ask questions to the confederate). Participant's SFA was measured by eye-tracked gaze duration at their own image relative to the confederates' video image and other places at the computer screen. Results show that high socially anxious participants were more self-focused in the critical phase, but less self-focused in the active phase than low socially anxious participants. In Experiment 2 women diagnosed with SAD (n = 32) and controls (n = 30) between 18 and 30 years conducted the same experiment. Compared to controls participants with SAD showed increased SFA across all four phases of the conversation, and SFA predicted increased self-rated anxiety during the conversation. In conclusion, in subclinical social anxiety SFA is high only when the interaction partner is critical, whereas instructions to ask questions to the confederate reduces subclinical socially anxious' SFA, while clinical SAD is characterized by heightened self-focused attention throughout the interaction. Results support theories that social anxiety disorder is maintained by SFA, and imply that interventions that lower SFA may help prevent and treat social anxiety disorder, but that SFA can also be adaptive in certain types of interaction, such as when receiving compliments.

    Full Text Available Social media technologies have attracted substantial attention among many types of users including researchers who have published studies for several years. This article presents an overview of trends in qualitative and mixed methods social media research literature published from 2007 through 2013. A collection of 229 qualitative studies were identified through a systematic literature review process. A subset of 55 of these articles report studies involving a combination of qualitative and quantitative methods. Articles were reviewed, analyzed, and coded through a qualitative content analysis approach. Overall trends are presented with respect to the entire collection of articles followed by an analysis of mixed methods research approaches identified in the subset of 55 studies. The most commonly used research approaches involved collecting data from people through interview, focus group, and survey methodologies. Content analysis was the second most commonly used approach whereby researchers use Facebook posts, Tweets (Twitter posts, YouTube videos, or other social media content as a data source. Many of the studies involving combinations of quantitative and qualitative data followed a design resembling Creswell and Plano Clark’s basic mixed methods typology (e.g., convergent parallel, explanatory sequential, and exploratory sequential.

    Augmentative and alternative communication (AAC) social media research is relatively new, and is built on a foundation of research on use of the Internet and social media by people with communication disabilities. Although the field is expanding to include a range of people who use AAC, there are limitations and gaps in research that will need to be addressed in order to keep pace with the rapid evolution of social media connectivity in assistive communication technologies. In this paper, we consider the aims, scope, and methodologies of AAC social media research, with a focus on social network sites. Lack of detailed attention to specific social network sites and little use of social media data limits the extent to which findings can be confirmed. Increased use of social media data across a range of platforms, including Instagram and YouTube, would provide important insights into the lives of people who use AAC and the ways in which they and their supporters use social media. New directions for AAC social media research are presented in line with those discussed at the social media research symposium at the International Society for Augmentative and Alternative Communication in Toronto, Canada, on August 12, 2016.

  19. The media politics of oil spills

    Energy Technology Data Exchange (ETDEWEB)

    Anderson, A.G. [University of Plymouth (United Kingdom). Dept. of Sociology

    2002-06-01

    This paper considers the ways in which news values shape the reporting of oil spills and the constraints under which media practitioners work. A series of oil spills since the late 1960s [including the Torrey Canyon (1967), the Exxon Valdez (1989), and the Sea Empress (1996)] have attracted considerable attention from the news media. The focus is upon the dynamics through which news sources, with their own particular vested interests, compete to secure representation of the issues. Media discourse on risk and the environment is, to a significant extent, a discourse dependent upon the voices of official ''experts''. Environmental organizations, industry, scientists and government offer their own particular competing accounts of the ''reality'' of the situation. Issues concerning differential access to the news media are crucial when considering who comes to define the event. Accordingly, the article examines the strategies adopted by the various news sources involved in influencing the symbolic representation of public issues. Media practitioners are faced with great problems in interpreting and explaining these competing claims. Relatively few journalists and broadcasters have a scientific training and perhaps one of the greatest problems is that by simplifying complex scientific information one inevitably distorts it. Frequently researchers make the assumption that it is possible to demonstrate a direct causal link between news media coverage and public attitudes. However, the paper calls for great caution in interpreting ''public opinion'' concerning environmental issues and concludes by arguing that news media representations may more usefully be viewed as the outcome of a battle among a selective range of news sources, each seeking to provide their own definition of the public representation of the issues.

  20. The flanker compatibility effect as a function of visual angle, attentional focus, visual transients, and perceptual load: a search for boundary conditions.

    1991-03-01

    When subjects must respond to a relevant center letter and ignore irrelevant flanking letters, the identities of the flankers produce a response compatibility effect, indicating that they are processed semantically at least to some extent. Because this effect decreases as the separation between target and flankers increases, the effect appears to result from imperfect early selection (attenuation). In the present experiments, several features of the focused attention paradigm were examined, in order to determine whether they might produce the flanker compatibility effect by interfering with the operation of an early selective mechanism. Specifically, the effect might be produced because the paradigm requires subjects to (1) attend exclusively to stimuli within a very small visual angle, (2) maintain a long-term attentional focus on a constant display location, (3) focus attention on an empty display location, (4) exclude onset-transient flankers from semantic processing, or (5) ignore some of the few stimuli in an impoverished visual field. The results indicate that none of these task features is required for semantic processing of unattended stimuli to occur. In fact, visual angle is the only one of the task features that clearly has a strong influence on the size of the flanker compatibility effect. The invariance of the flanker compatibility effect across these conditions suggests that the mechanism for early selection rarely, if ever, completely excludes unattended stimuli from semantic analysis. In addition, it shows that selective mechanisms are relatively insensitive to several factors that might be expected to influence them, thereby supporting the view that spatial separation has a special status for visual selective attention.

  1. Attention.

    Callahan, Patrick M; Terry, Alvin V

    2015-01-01

    The ability to focus one's attention on important environmental stimuli while ignoring irrelevant stimuli is fundamental to human cognition and intellectual function. Attention is inextricably linked to perception, learning and memory, and executive function; however, it is often impaired in a variety of neuropsychiatric disorders, including Alzheimer's disease, schizophrenia, depression, and attention deficit hyperactivity disorder (ADHD). Accordingly, attention is considered as an important therapeutic target in these disorders. The purpose of this chapter is to provide an overview of the most common behavioral paradigms of attention that have been used in animals (particularly rodents) and to review the literature where these tasks have been employed to elucidate neurobiological substrates of attention as well as to evaluate novel pharmacological agents for their potential as treatments for disorders of attention. These paradigms include two tasks of sustained attention that were developed as rodent analogues of the human Continuous Performance Task (CPT), the Five-Choice Serial Reaction Time Task (5-CSRTT) and the more recently introduced Five-Choice Continuous Performance Task (5C-CPT), and the Signal Detection Task (SDT) which was designed to emphasize temporal components of attention.

  2. Attentional ability among survivors of leukaemia.

    1999-04-01

    Attentional ability in 19 survivors of acute lymphoblastic leukaemia and 19 sibling controls was assessed using a neuropsychological model of attention. Analysis revealed that children who had received treatment for leukaemia exhibited significantly poorer performance on measures of the "focus encode" and "focus execute" elements of attention and on measures of the ability to respond to external cues and feedback. No significant differences in performance were found for measures of sustained attention and the ability to shift attention. These results indicate that children who have received treatment for leukaemia may experience highly specific attentional deficits that could have an impact on academic performance, particularly mathematical and reading skills. It is suggested that this underlying attentional deficit might be the source of the neuropsychological sequelae associated with the disease. Future attempts at remediation should incorporate activities specifically designed to ameliorate focusing difficulties.

  3. Sleep and Media Screens in Pediatric Ages

    Full Text Available Introduction: Sleep plays an essential role in children’s physical, emotional and behavioral health. Understanding the sleep architecture, sleep duration requirements as well as the interference of media screens activity with sleep across pediatric ages is essential in order to provide an adequate anticipatory guidance for the children’s parents. Objectives: To review current knowledge on sleep physiology with a particular focus in sleep duration requirements across pediatric ages and on the influence of media screen activity on children and adolescent sleep. Methods: Revision of meta-analysis research studies, systematic reviews, standards of clinical orientation and original research published in Portuguese or English between 01/2000 and 08/2017 on Pubmed / Medline using the following MeSH terms: sleep; sleep requirements; sleep physiology; media screen; child and neurodevelopment. Development: Sleep architecture and sleep duration requirements undergo constant change with age. Despite interindividual differences, optimal sleep duration intervals as well as nap times, which constitute an essential component of children’s sleep, should be followed. Along children’s age progression, other parameters need to be considered in order to maintain optimal sleep quality. The restriction of media screen use at bedtime assumes special relevance, as there is growing evidence pointing towards an association between shortened sleep time and the misuse of screen devices. Adolescents represent a particularly vulnerable population to media screens effects. Importantly, screen overuse and media content may be responsible for higher propensity for obesity, risky behavior, depression, impaired academic performance, decreased social skills and attention difficulties. Conclusion: Anticipatory guidance for parents addressing sleep optimization and media exposure should be routinely provided as a part of health follow-up. Physicians should be capacitated to

    Attention deficit hyperactivity disorder (ADHD) is the most common behavioral problems that cause hyperactivity, attention deficits, academic failure, and emotional and behavioral problems in preschool and elementary school that is often hidden from the parents' eyes. The aim of this study was to determine the effectiveness of parent-based cognitive-behavioral therapy (CBT) on ADHD symptoms (including attention deficit disorder, restlessness, and impulsivity), overweight and self-esteem of 6-11-year-old obese children with attention deficit hyperactivity in Isfahan. This quasi-experimental study was carried out on 40 children aged 6-11 years with ADHD and overweight or obesity (above the 85 th percentile in weight for age, height, and sex diagram) that their parents referred to Isfahan child and adolescent psychiatric clinic of Ali Asghar Hospital in 2015. For twenty patients, only ADHD treatment was applied, and they received no other intervention, but the others in experimental group participated in CBT sessions. Analysis tools were Coppersmith Self-Esteem Scale, ADHD conners' test, and the body mass index (BMI). Data were analyzed using analysis of variance with repeated measurements. CBT by teaching parents had a significant effect on ADHD symptoms, the self-esteem of overweight and obese children with ADHD in posttest and follow-up. The results also showed that had a significant effect on ADHD symptoms, overweight and self-esteem of the obese children with ADHD ( P < 0.001). Parents focused CBT can be considered as a complementary treatment for reducing ADHD symptoms and BMI and increased self-esteem in the obese ADHD children.

  5. Working memory benefits creative insight, musical improvisation, and original ideation through maintained task-focused attention.

    Anecdotes from creative eminences suggest that executive control plays an important role in creativity, but scientific evidence is sparse. Invoking the Dual Pathway to Creativity Model, the authors hypothesize that working memory capacity (WMC) relates to creative performance because it enables persistent, focused, and systematic combining of elements and possibilities (persistence). Study 1 indeed showed that under cognitive load, participants performed worse on a creative insight task. Study 2 revealed positive associations between time-on-task and creativity among individuals high but not low in WMC, even after controlling for general intelligence. Study 3 revealed that across trials, semiprofessional cellists performed increasingly more creative improvisations when they had high rather than low WMC. Study 4 showed that WMC predicts original ideation because it allows persistent (rather than flexible) processing. The authors conclude that WMC benefits creativity because it enables the individual to maintain attention focused on the task and prevents undesirable mind wandering.

    Attention helps manage the information held in visual working memory (vWM). Perceptual attention selects the stimuli to be represented in vWM, whereas internal attention prioritizes information already in vWM. In the present study we assessed the spatial precision of perceptual and internal attention in vWM. Participants encoded eight colored dots for a local-recognition test. To manipulate attention, a cue indicated the item most likely to be tested (~65% validity). The cue appeared either before the onset of the memory array (precue) or during the retention interval (retrocue). The precue guides perceptual attention to gate encoding into vWM, whereas the retrocue guides internal attention to prioritize the cued item within vWM. If attentional selection is spatially imprecise, attention should be preferentially allocated to the cued location, with a gradual drop-off of attention over space to nearby uncued locations. In this case, memory for uncued locations should vary as a function of their distance from the cued location. As compared to a no-cue condition, memory was better for validly cued items but worse for uncued items. The spatial distance between the uncued and cued locations modulated the cuing costs: Items close in space to the cued location were insulated from cuing costs. The extension of this spatial proximity effect was larger for precues than for retrocues, mostly because the benefits of attention were larger for precues. These results point to similar selection principles between perceptual and internal attention and to a critical role of spatial distance in the selection of visual representations.

    The aim of this paper is to present results from a study that examines the use of the Internet for collecting material and the attention people pay to advertisements through different media sources in the context of services. A representative stratified sample of 301 respondents of foreign arrivals of tourists in the Athens airport, Greece, collected in June and July 2014 was employed. We present which social media sources and user-generated material that promote advertisements were found to be important in capturing people's attention. Results illustrated the significant role that advertisements on Facebook play on the way people pay attention to. In fact, Facebook was found to be the second most important medium that people use when collecting material. In addition, Facebook was found to be the third source that respondents strongly agreed that they pay attention to advertisements, with the official websites/blogs to be the first source and travel guidebooks and travel magazines to follow, leaving traditional media far behind. Implications and suggestions are provided for online communication programs that may incorporate social media in services marketing communications campaigns. Libraries and corporate bodies may employ social media for advertising their services based on the significant role social media have.

  8. Non-erotic thoughts, attentional focus, and sexual problems in a community sample.

    According to Barlow's model of sexual dysfunction, anxiety in sexual situations leads to attentional focus on sexual performance at the expense of erotic cues, which compromises sexual arousal. This negative experience will enhance anxiety in future sexual situations, and non-erotic thoughts (NETs) relevant to performance will receive attentional priority. Previous research with student samples (Purdon & Holdaway, 2006; Purdon & Watson, 2010) has found that people experience many types of NETs in addition to performance-relevant thoughts, and that, consistent with Barlow's model, the frequency of and anxiety evoked by these thoughts is positively associated with sexual problems. Extending this previous work, the current study found that, in a community sample of women (N = 81) and men (N = 72) in long-term relationships, women were more likely to report body image concerns and external consequences of the sexual activity, while men were more likely to report performance-related concerns. Equally likely among men and women were thoughts about emotional consequences of the sexual activity. Regardless of thought content, experiencing more frequent NETs was associated with more sexual problems in both women and men. Moreover, as per Barlow's model, greater negative affect in anticipation of and during sexual activity predicted greater frequency of NETs and greater anxiety in response to NETs was associated with greater difficulty dismissing the thoughts. However, greater difficulty in refocusing on erotic thoughts during sexual activity uniquely predicted more sexual problems above the frequency and dismissability of NETs. Together, these data support the cognitive interference mechanism implicated by Barlow's causal model of sexual dysfunction and have implications for the treatment of sexual problems.

    A robust body of scientific research explores the effects of violent media on youths. For practitioners, the volume of interdisciplinary research and controversial findings can be confusing and difficult to generalize for best practice. This article briefly reviews the literature and presents guidelines for parenting and treating youths exposed and enmeshed in violent media. Attention is given to at-risk populations and children presenting with aggressive, violent, and antisocial behavior. Guidelines assume a family based, cognitive-behavioral approach suitable for the eclectic practitioner, with a focus on the complex, developmental, and ecological factors that contribute to presenting symptoms.

  12. Neural mechanisms of human perceptual choice under focused and divided attention

    2015-01-01

    Perceptual decisions occur after evaluation and integration of momentary sensory inputs, and dividing attention between spatially disparate sources of information impairs decision performance. However, it remains unknown whether dividing attention degrades the precision of sensory signals, precludes their conversion into decision signals, or dampens the integration of decision information towards an appropriate response. Here we recorded human electroencephalographic (EEG) activity whilst participants categorised one of two simultaneous and independent streams of visual gratings according to their average tilt. By analyzing trial-by-trial correlations between EEG activity and the information offered by each sample, we obtained converging behavioural and neural evidence that dividing attention between left and right visual fields does not dampen the encoding of sensory or decision information. Under divided attention, momentary decision information from both visual streams was encoded in slow parietal signals without interference but was lost downstream during their integration as reflected in motor mu- and beta-band (10–30 Hz) signals, resulting in a ‘leaky’ accumulation process which conferred greater behavioural influence to more recent samples. By contrast, sensory inputs that were explicitly cued as irrelevant were not converted into decision signals. These findings reveal that a late cognitive bottleneck on information integration limits decision performance under divided attention, and place new capacity constraints on decision-theoretic models of information integration under cognitive load.

The three groups share the experience of trying to build a life in another country (Norway, while their family and friends in the “homeland” experience political violence and civil war. We identify a notable sense of frustration and skepticism towards Norwegian media. The informants actively use international media and media from the homeland, and often find these more reliable and providing more relevant information than Norwegian media. They also voice a strong critique of the ways in which the media react when “the others” are victims of violence, and several participants react negatively towards the neglect of positive reporting from their respective homelands, and to media hostility towards Muslims.

    People with attention-deficit/hyperactivity disorder (ADHD) have difficulties sustaining their attention on external tasks. Such attentional lapses have often been characterized as the simple opposite of external sustained attention, but the different types of attentional lapses, and the subjective experiences to which they correspond, remain unspecified. In this study, we showed that unmedicated children (ages 6-12) with ADHD, when probed during a standard go/no-go task, reported more mind blanking (a mental state characterized by the absence of reportable content) than did control participants. This increase in mind blanking happened at the expense of both focused and wandering thoughts. We also found that methylphenidate reverted the level of mind blanking to baseline (i.e., the level of mind blanking reported by control children without ADHD). However, this restoration led to mind wandering more than to focused attention. In a second experiment, we extended these findings to adults who had subclinical ADHD. These results suggest that executive functions impaired in ADHD are required not only to sustain external attention but also to maintain an internal train of thought.

In general, global features were processed faster than local features. However, this global precedence effect was reduced after viewing cute images. Results show that participants performed tasks requiring focused attention more carefully after viewing cute images. This is interpreted as the result of a narrowed attentional focus induced by the cuteness-triggered positive emotion that is associated with approach motivation and the tendency toward systematic processing. For future applications, cute objects may be used as an emotion elicitor to induce careful behavioral tendencies in specific situations, such as driving and office work.

    Full Text Available Frontal midline theta rhythm (Fmθ appears widely distributed over medial prefrontal areas in EEG recordings, indicating focused attention. Although mental calculation is often used as an attention-demanding task, little has been reported on calculation-related activation in Fmθ experiments. In this study we used spatially filtered MEG and permutation analysis to precisely localize cortical generators of the magnetic counterpart of Fmθ, as well as other sources of oscillatory activity associated with mental calculation processing (i.e., arithmetic subtraction. Our results confirmed and extended earlier EEG/MEG studies indicating that Fmθ during mental calculation is generated in the dorsal anterior cingulate and adjacent medial prefrontal cortex. Mental subtraction was also associated with gamma event-related synchronization, as an index of activation, in right parietal regions subserving basic numerical processing and number-based spatial attention. Gamma event-related desynchronization appeared in the right lateral prefrontal cortex, likely representing a mechanism to interrupt neural activity that can interfere with the ongoing cognitive task.

  3. “Straight” Acting: Changing Image of Queer-Masculinity in Media Representation

    Full Text Available In this essay, I critically examine media representation of Welsh rugby legend Gareth Thomas, with a specific focus on the construction of his masculinity as an outing gay celebrity. The existing critical scholarship has studied various forms of media representation of queer images. But they did not examine how unconventional queer representation interacts with the normative gender performance. This paper investigates mainstream media’s discursive construction of masculine gay male. The findings call our attention to the emergence of macho gay characterization, which supports the hegemonic domination of heterosexual normativity. The stigmatization of gay-ness as the deviated other is rationalized through illegitimating its positions in the public spheres, marginalizing non-masculine gay characters, and erasing the larger socio-political condition that oppresses closeted gay athletes.

  4. Neural mechanisms of human perceptual choice under focused and divided attention.

    Perceptual decisions occur after the evaluation and integration of momentary sensory inputs, and dividing attention between spatially disparate sources of information impairs decision performance. However, it remains unknown whether dividing attention degrades the precision of sensory signals, precludes their conversion into decision signals, or dampens the integration of decision information toward an appropriate response. Here we recorded human electroencephalographic (EEG) activity while participants categorized one of two simultaneous and independent streams of visual gratings according to their average tilt. By analyzing trial-by-trial correlations between EEG activity and the information offered by each sample, we obtained converging behavioral and neural evidence that dividing attention between left and right visual fields does not dampen the encoding of sensory or decision information. Under divided attention, momentary decision information from both visual streams was encoded in slow parietal signals without interference but was lost downstream during their integration as reflected in motor mu- and beta-band (10-30 Hz) signals, resulting in a "leaky" accumulation process that conferred greater behavioral influence to more recent samples. By contrast, sensory inputs that were explicitly cued as irrelevant were not converted into decision signals. These findings reveal that a late cognitive bottleneck on information integration limits decision performance under divided attention, and places new capacity constraints on decision-theoretic models of information integration under cognitive load.

    Technology has the potential to impact cognition in many ways. Here we contrast two forms of technology usage: (1) media multitasking (i.e., the simultaneous consumption of multiple streams of media, such a texting while watching TV) and (2) playing action video games (a particular subtype of video games). Previous work has outlined an association between high levels of media multitasking and specific deficits in handling distracting information, whereas playing action video games has been associated with enhanced attentional control. Because these two factors are linked with reasonably opposing effects, failing to take them jointly into account may result in inappropriate conclusions as to the impacts of technology use on attention. Across four tasks (AX-continuous performance, N-back, task-switching, and filter tasks), testing different aspects of attention and cognition, we showed that heavy media multitaskers perform worse than light media multitaskers. Contrary to previous reports, though, the performance deficit was not specifically tied to distractors, but was instead more global in nature. Interestingly, participants with intermediate levels of media multitasking sometimes performed better than both light and heavy media multitaskers, suggesting that the effects of increasing media multitasking are not monotonic. Action video game players, as expected, outperformed non-video-game players on all tasks. However, surprisingly, this was true only for participants with intermediate levels of media multitasking, suggesting that playing action video games does not protect against the deleterious effect of heavy media multitasking. Taken together, these findings show that media consumption can have complex and counterintuitive effects on attentional control.

  6. The allocation of attention to learning of goal-directed actions: A cognitive neuroscience framework focusing on the basal ganglia

    Liz eFranz

    2012-12-01

    Full Text Available The present paper builds on the idea that attention is largely in service of our actions. A framework and model which captures the allocation of attention for learning of goal-directed actions is proposed and developed. This framework highlights an evolutionary model based on the notion that rudimentary brain functions have become embedded into increasingly higher levels of networks which all contribute to adaptive learning. Background literature is presented alongside key evidence based on experimental studies in the so-called ‘split-brain’ (surgically divided cerebral hemispheres with a key focus on bimanual actions. The proposed multilevel cognitive-neural system of attention is built upon key processes of a highly-adaptive basal-ganglia-thalamic-cortical system. Although overlap with other existing findings and models is acknowledged where appropriate, the proposed framework is an original synthesis of cognitive experimental findings with supporting evidence of a neural system and a carefully formulated model of attention. It is the hope that this new synthesis will be informative in fields of cognition and other fields of brain sciences and will lead to new avenues for experimentation across domains.

    Research on the social implications of adolescent technology use often focuses on identifying and preventing risk. However, adolescence is also a time of rapidly expanding capacities, expectations of autonomy, and identity exploration. In this article, we highlight findings from research in the field of youth civic development, which point to the importance of youth civic engagement during adolescence for later adult civic engagement as well as for promoting positive developmental outcomes. Researchers suggest that certain forms of Internet use (such as information seeking, social network site use, media production, and participation in online communities) promote civic engagement and that digital tools play an important role in youth empowerment efforts. In this article, we suggest a need for greater attention to efforts to promote digital media competencies among adolescents and for greater coordination of research on adolescent risk and adolescent autonomy and empowerment related to Internet use.

    Perceptual learning is an important means for the brain to maintain its agility in a dynamic environment. Top-down focal attention, which selects task-relevant stimuli against competing ones in the background, is known to control and select what is learned in adults. Still unknown, is whether the adult brain is able to learn highly visible information beyond the focus of top-down attention. If it is, we should be able to reveal a purely stimulus-driven perceptual learning occurring in functions that are largely determined by the early cortical level, where top-down attention modulation is weak. Such an automatic, stimulus-driven learning mechanism is commonly assumed to operate only in the juvenile brain. We performed perceptual training to reduce sensory eye dominance (SED), a function that taps on the eye-of-origin information represented in the early visual cortex. Two retinal locations were simultaneously stimulated with suprathreshold, dichoptic orthogonal gratings. At each location, monocular cueing triggered perception of the grating images of the weak eye and suppression of the strong eye. Observers attended only to one location and performed orientation discrimination of the gratings seen by the weak eye, while ignoring the highly visible gratings at the second, unattended, location. We found SED was not only reduced at the attended location, but also at the unattended location. Furthermore, other untrained visual functions mediated by higher cortical levels improved. An automatic, stimulus-driven learning mechanism causes synaptic alterations in the early cortical level, with a far-reaching impact on the later cortical levels. Copyright © 2011 Elsevier Ltd.

    In democracies where multitudes yield political influence, so does broadcast media that reaches those multitudes. However, broadcast media may not be powerful simply because it reaches a certain audience, but because each of the recipients is aware of that fact. That is, watching broadcast media can evoke a state of shared attention, or the perception of simultaneous coattention with others. Whereas past research has investigated the effects of shared attention with a few socially close others (i.e., friends, acquaintances, minimal ingroup members), we examine the impact of shared attention with a multitude of unfamiliar others in the context of televised broadcasting. In this paper, we explore whether shared attention increases the psychological impact of televised political speeches, and whether fewer numbers of coattending others diminishes this effect. Five studies investigate whether the perception of simultaneous coattention, or shared attention, on a mass broadcasted political speech leads to more extreme judgments. The results indicate that the perception of synchronous coattention (as compared with coattending asynchronously and attending alone) renders persuasive speeches more persuasive, and unpersuasive speeches more unpersuasive. We also find that recall memory for the content of the speech mediates the effect of shared attention on political persuasion. The results are consistent with the notion that shared attention on mass broadcasted information results in deeper processing of the content, rendering judgments more extreme. In all, our findings imply that shared attention is a cognitive capacity that supports large-scale social coordination, where multitudes of people can cognitively prioritize simultaneously coattended information.

    Top-down controlled selective or divided attention to sounds and visual objects, as well as bottom-up triggered attention to auditory and visual distractors, has been widely investigated. However, no study has systematically compared brain activations related to all these types of attention. To this end, we used functional magnetic resonance imaging (fMRI) to measure brain activity in participants performing a tone pitch or a foveal grating orientation discrimination task, or both, distracted by novel sounds not sharing frequencies with the tones or by extrafoveal visual textures. To force focusing of attention to tones or gratings, or both, task difficulty was kept constantly high with an adaptive staircase method. A whole brain analysis of variance (ANOVA) revealed fronto-parietal attention networks for both selective auditory and visual attention. A subsequent conjunction analysis indicated partial overlaps of these networks. However, like some previous studies, the present results also suggest segregation of prefrontal areas involved in the control of auditory and visual attention. The ANOVA also suggested, and another conjunction analysis confirmed, an additional activity enhancement in the left middle frontal gyrus related to divided attention supporting the role of this area in top-down integration of dual task performance. Distractors expectedly disrupted task performance. However, contrary to our expectations, activations specifically related to the distractors were found only in the auditory and visual cortices. This suggests gating of the distractors from further processing perhaps due to strictly focused attention in the current demanding discrimination tasks. Copyright © 2017 Elsevier B.V.

    Full Text Available Conceptual evolution of the Internet and Web, substantiated through Web 2.0 and the emergence of online social networks, reinvented the way that enterprises interact with their customers. Museums, as cultural institutions with an important mission, are not unaffected by that change, however. In order to fulfil their duties and societal purpose successfully, they have to attract visitors’ attention and engage the public effectively in a highly competitive and saturated environment. The goal of this paper is to analyze and compare the social media presence of museums in two European capitals. It focuses on museums in Prague and Berlin, and considers their general Web presence and the dynamics of activities on Facebook. In order to understand the integrative social media approach of museums in both regions, we investigated additionally Twitter and Youtube presence among museums with a Facebook account. The study reveals a lower presence of Prague museums both on the Web and in the identified social media networks, in comparison to Berlin museums. Moreover, we conclude that the presence of both regional museums on social media networks is low, while the integration and simultaneous application of more networks at the same time are negligible, both for Prague and Berlin museums.

    Social media, including mobile technologies and social networking sites, are being used increasingly as part of human immunodeficiency virus (HIV) prevention and treatment efforts. As an important avenue for communication about HIV, social media use may continue to increase and become more widespread. The objective of this paper is to present a comprehensive systematic review of the current published literature on the design, users, benefits, and limitations of using social media to communicate about HIV prevention and treatment. This review paper used a systematic approach to survey all literature published before February 2014 using 7 electronic databases and a manual search. The inclusion criteria were (1) primary focus on communication/interaction about HIV/acquired immunodeficiency syndrome (AIDS), (2) discusses the use of social media to facilitate communication, (3) communication on the social media platform is between individuals or a group of individuals rather than the use of preset, automated responses from a platform, (4) published before February 19, 2014, and (5) all study designs. The search identified 35 original research studies. Thirty studies had low or unclear risk of at least one of the bias items in the methodological quality assessment. Among the 8 social media platform types described, short message service text messaging was most commonly used. Platforms served multiple purposes including disseminating health information, conducting health promotion, sharing experiences, providing social support, and promoting medication adherence. Social media users were diverse in geographic location and race/ethnicity; studies commonly reported users aged 18-40 years and users with lower income. Although most studies did not specify whether use was anonymous, studies reported the importance of anonymity in social media use to communicate about HIV largely due to the stigma associated with HIV.

    Television viewing has been associated with greater subsequent attention problems in children. Few studies have examined the possibility of a similar association between video games and attention problems, and none of these has used a longitudinal design. A sample of 1323 middle childhood participants were assessed during a 13-month period by parent- and child-reported television and video game exposure as well as teacher-reported attention problems. Another sample of 210 late adolescent/early adult participants provided self-reports of television exposure, video game exposure, and attention problems. Exposure to television and video games was associated with greater attention problems. The association of television and video games to attention problems in the middle childhood sample remained significant when earlier attention problems and gender were statistically controlled. The associations of screen media and attention problems were similar across media type (television or video games) and age (middle childhood or late adolescent/early adult). Viewing television and playing video games each are associated with increased subsequent attention problems in childhood. It seems that a similar association among television, video games, and attention problems exists in late adolescence and early adulthood. Research on potential risk factors for attention problems should be expanded to include video games in addition to television.

    How is science represented by the media? Who defines what counts as a risk, threat or hazard, and why? In what ways do media images of science shape public perceptions? What can cultural and media studies tell us about current scientific controversies? "Media, Risk and Science" is an exciting exploration into an array of important issues, providing a much needed framework for understanding key debates on how the media represent science and risk. In a highly effective way, Stuart Allan weaves together insights from multiple strands of research across diverse disciplines. Among the themes he examines are: the role of science in science fiction, such as "Star Trek"; the problem of 'pseudo-science' in "The X-Files"; and how science is displayed in science museums. Science journalism receives particular attention, with the processes by which science is made 'newsworthy' unravelled for careful scrutiny. The book also includes individual chapters devoted to how the media portray environmental risks, HIV-AIDS, food s...

However, very little research has been undertaken on how working in the university may contextualize the ways in which academic workers participate in activist media projects. Focusing on three such projects – Media Democracy Day, Open Media, and NewsWatch Canada – this article draws upon elements of political economy and Bourdieu’s field theory to consider how the different characters of the academic and activist fields work to enable and constrain the abilities of faculty to engage with them.

    Different approaches like providing augmented feedback (aF), applying an external focus of attention (EF), or rewarding participants with money (RE) have been shown to instantly enhance motor performance. So far, these approaches have been tested either in separate studies or directly against each other. However, there is no study that combined aF, EF, and/or RE to test whether this provokes additional benefits. The aim of the present study was therefore to identify the most powerful combination. Eighteen participants performed maximal countermovement jumps in six different conditions: neutral (NE), aF, RE, aF + EF, aF + RE, and aF + EF + RE. Participants demonstrated the highest jump heights with aF + EF, followed by aF + EF + RE, aF + RE, aF, RE, and finally, NE. Activity of the M. rectus femoris differed significantly between conditions resulting in lower muscular activity in aF + EF and aF + EF + RE compared with NE. All other parameters, such as ground reaction forces and joint angles, were comparable across conditions. This is the first study showing superior performance when combining aF with EF. As reduced muscular activity was found only in conditions with EF, it is argued in line with the constrained action hypothesis that adopting an EF improves movement efficiency. In contrast, aF seems to rather enhance (intrinsic) motivation. However, monetary reward did not further amplify performance.

    Focused attention meditations have been shown to improve psychological health and wellbeing and are nowadays an integral part of many psychotherapies. While research on the neural correlates of focused attention meditation is increasing, findings vary on whether meditations are associated with high or low activity in the default mode network (DMN). To clarify the relationship between focused attention meditation and the activity in DMN regions, it may be helpful to distinguish internal and external attention as well as different phases within one meditation: During focused attention meditation, the practitioner switches between mindful attention, mind-wandering and refocusing. Here, we employed a thought-probe paradigm to study the neural correlates of these different phases. Twenty healthy, meditation naïve participants were introduced to external (mindfulness of sound) and internal (mindfulness of breathing) attention meditation and then practiced the meditation at home for four consecutive days. They then performed the same focused attention meditations during fMRI scanning, in four runs alternating between internal and external attention. At pseudorandom intervals, participants were asked whether they had just been focused on the task (mindful attention) or had been distracted (mind-wandering). During mindful attention, brain regions typically associated with the DMN, such as the medial prefrontal cortex, posterior cingulate cortex and left temporoparietal junction showed significantly less neural activation compared to mind-wandering phases. Reduced activity of the DMN was found during both external and internal attention, with stronger deactivation in the posterior cingulate cortex during internal attention compared to external attention. Moreover, refocusing after mind-wandering was associated with activity in the left inferior frontal gyrus. Our results support the theory that mindful attention is associated with reduced DMN activity compared to mind

    Full Text Available Abstract Background Motor learning research has had little impact on clinical applications and rarely extended to research about how older adults learn motor skills. There is consistent evidence that motor skill performance and learning can be enhanced by giving learners instructions that direct their attention. The aim of this study was to test whether elderly individuals that receive an external focus instruction during training of dynamic balance skills would learn in a different manner compared to individuals that received an internal focus instruction. Methods This randomised trial included 26 older persons (81 ± 6 years that were training functional balance twice a week for the duration of 5 weeks. Learning outcomes were recorded after every training session. Weight shifting score and dynamic balance parameters (Biodex Balance System, components of the Extended Timed-Get-Up-and-Go test, five chair rises, and falls efficacy (FES-I was assessed at baseline and post-intervention. Results Participation for training sessions was 94%. No differences between groups were found following 5 weeks of training for weight shifting score, dynamic balance index and dynamic balance time (p p = 0.16, p Sit-to-stand, p = .036; Gait initiation, p = .039; Slow down, stop, turnaround, and sit down, p = 0.011 and the Fes-I (p = 0.014 showed improvements for the total group, indicating that function improved compared to baseline. Conclusion A 5-week balance training improved weight shifting scores and dynamic balance parameters as well as functional abilities. The observed improvements were independent from the type of attentional focus instructions. The findings provide support for the proposition of different motor learning principles in older adults compared to younger adults. Trial Registration ISRCTN44627088

  7. Theories of otitis media pathogenesis, with a focus on Indigenous children.

    Science.gov (United States)

    Wiertsema, Selma P; Leach, Amanda J

    2009-11-02

    Otitis media is a common childhood illness associated with hearing loss, social disadvantage and medical costs. Prevalence and severity are high among Indigenous children. Respiratory bacterial and viral pathogens ascend the eustachian tube from the nasopharynx to the middle ear, causing inflammation, fluid accumulation, and bulging of the tympanic membrane, with or without pain. Among Australian Indigenous children, ear disease commences earlier in life, and involves multiple strains of bacterial pathogens at high density that persist longer. Persistent nasal discharge, overcrowded living conditions (particularly exposure to many children) and poor facilities for washing children perpetuate a vicious cycle of transmission and infection. Risk factors include environmental tobacco smoke, season, lack of breastfeeding, younger age and immature immune system, and possibly genetic factors. The innate immune system is a critical first response to infection, particularly as passive maternal antibodies decline and during the maturation of the infant adaptive immune response. The relative contributions of innate factors to protection from otitis media are currently not well understood. A diversity of antibodies that target strain-specific and conserved antigens are generated in response to natural exposure to otitis media pathogens (or to vaccines). Deficiencies in these antibodies may explain susceptibility to recurrent infections. Incremental contributions from all these elements are likely to be important in otitis media susceptibility versus protection. Effective medical and social strategies to prevent early age of onset are urgently needed.

    As media attention has become a dominating force within the design economy, visibility became the combustible that fuels the current design industry. Designed objects were once real products, but are now often prototypes, props to be exhibited and photographed, whose role is to fill space in the media, raise the media profile of their creators and convey the name of brokers, sponsors and partners. As a result celebrated design objects are now rare pieces that are highly visible in the virtual...

  9. User-Generated Social Media Events in Tourism

    Full Text Available Social media and mobile technologies have revolutionised communication and particular attention has been given to user-generated content (UGC and the formation of online communities; however, little attention has been given to tourist events entirely generated by users through social media. This paper aims to define and characterise the phenomenon of tourism user-generated events (UGEs through social media around the user’s new empowered role and to assess user-generated social media events’ online socialness. It is also our aim to provide a useful mixed-methodology analysis framework for UGEs in relation to social media and to highlight their interest for organisations. The methodological approach includes a quantitative model to store, analyse and compare events’ online socialness, which is combined with qualitative, participant observation at the events. This approach is applied to the analysis of three Instagram meetups organised by a specific online community at Catalan ski resorts. The paper’s results show the differential characteristic of tourism UGEs: user initiative and empowerment, full organisation and structure, great social media use and UGC production, brand dissemination, attraction capacity, strong online community bond and faithfulness. With UGEs, an event management paradigm shift occurs as organisations are no longer the main initiators and controllers of the event.

  10. Quality of life of children with otitis media - a cohort study

    DEFF Research Database (Denmark)

    Ryborg, Christina T; Søndergaard, Jens; Lous, Jørgen

    2014-01-01

    BACKGROUND: Studies about health-related quality of life (HRQOL) in children with otitis media have primarily focused on short-term effects of the disease, and how treatment with insertion of ventilation tubes (VTs) affects the HRQOL. More knowledge is needed about how long-term HRQOL is associated...... with different factors like insertion of VT and use of antibiotics. OBJECTIVE: We aimed to analyse HRQOL in children with otitis media 1 year after inclusion and to what extent insertion of VT, use of antibiotics, diagnoses, symptoms in the children, day-care attention, parental absence from work and parental...... was significantly improved after 13 months. The improvement of HRQOL was significantly lower for children with sleep problems compared with children without sleep problems. The improvement in HRQOL was significantly lower in children whose parents had been absent from work during the preceding 3 months due...

  11. Pupil size reflects the focus of feature-based attention.

    Science.gov (United States)

    Binda, Paola; Pereverzeva, Maria; Murray, Scott O

    2014-12-15

    We measured pupil size in adult human subjects while they selectively attended to one of two surfaces, bright and dark, defined by coherently moving dots. The two surfaces were presented at the same location; therefore, subjects could select the cued surface only on the basis of its features. With no luminance change in the stimulus, we find that pupil size was smaller when the bright surface was attended and larger when the dark surface was attended: an effect of feature-based (or surface-based) attention. With the same surfaces at nonoverlapping locations, we find a similar effect of spatial attention. The pupil size modulation cannot be accounted for by differences in eye position and by other variables known to affect pupil size such as task difficulty, accommodation, or the mere anticipation (imagery) of bright/dark stimuli. We conclude that pupil size reflects not just luminance or cognitive state, but the interaction between the two: it reflects which luminance level in the visual scene is relevant for the task at hand.

    Selective auditory attention causes a relative enhancement of the neural representation of important information and suppression of the neural representation of distracting sound, which enables a listener to analyze and interpret information of interest. Some studies suggest that in both vision and in audition, the “unit” on which attention operates is an object: an estimate of the information coming from a particular external source out in the world. In this view, which object ends up in the...

  14. Attention in Urban Foraging

    Directory of Open Access Journals (Sweden)

    Malcolm McCullough

    2013-05-01

    Full Text Available This position paper argues how there has to be much more to smart city learning than just wayshowing, and something better as augmented reality than covering the world with instructions. Attention has become something for many people to know better in an age of information superabundance. Embodied cognition explains how the work-ings of attention are not solely a foreground task, as if attention is something to pay. As digital media appear in ever more formats and contexts, their hybrids with physical form increasing influence how habitual engagement with persistent situations creates learning. Ambient information can just add to the distraction by multitasking, or it can support more favorable processes of shifting among different kinds of information with a particular intent. As one word for this latter process, foraging deserves more consideration in smart city learning

    2012-09-01

    Full Text Available Research on visual attention has shown that Americans tend to focus more on focal objects of a scene while Asians attend to the surrounding environment. The panels of comic books— the narrative frames in sequential images—highlight aspects of a scene comparably to how attention becomes focused on parts of a spatial array. Thus, we compared panels from American and Japanese comics to explore cross-cultural cognition beyond behavioral experimentation by looking at the expressive mediums produced by individuals from these cultures. This study compared the panels of two genres of American comics (Independent and Mainstream comics with mainstream Japanese manga to examine how different cultures and genres direct attention through the framing of figures and scenes in comic panels. Both genres of American comics focused on whole scenes as much as individual characters, while Japanese manga individuated characters and parts of scenes. We argue that this framing of space from American and Japanese comic books simulate a viewer’s integration of a visual scene, and is consistent with the research showing cross-cultural differences in the direction of attention.

  17. Misrepresentation of neuroscience data might give rise to misleading conclusions in the media: the case of attention deficit hyperactivity disorder.

    Directory of Open Access Journals (Sweden)

    Francois Gonon

    Full Text Available BACKGROUND: There is often a huge gap between neurobiological facts and firm conclusions stated by the media. Data misrepresentation in the conclusions and summaries of neuroscience articles might contribute to this gap. METHODOLOGY/PRINCIPAL FINDINGS: Using the case of attention deficit hyperactivity disorder (ADHD, we identified three types of misrepresentation. The first relies on prominent inconsistencies between results and claimed conclusions and was observed in two scientific reports dealing with ADHD. Only one out of the 61 media articles echoing both scientific reports adequately described the results and, thus questioned the claimed conclusion. The second type of misrepresentation consists in putting a firm conclusion in the summary while raw data that strongly limit the claim are only given in the results section. To quantify this misrepresentation we analyzed the summaries of all articles asserting that polymorphisms of the gene coding for the D4 dopaminergic receptor are associated with ADHD. Only 25 summaries out of 159 also mentioned that this association confers a small risk. This misrepresentation is also observed in most media articles reporting on ADHD and the D4 gene. The third misrepresentation consists in extrapolating basic and pre-clinical findings to new therapeutic prospects in inappropriate ways. Indeed, analysis of all ADHD-related studies in mice showed that 23% of the conclusions were overstated. The frequency of this overstatement was positively related with the impact factor of the journal. CONCLUSION/SIGNIFICANCE: Data misrepresentations are frequent in the scientific literature dealing with ADHD and may contribute to the appearance of misleading conclusions in the media. In synergy with citation distortions and publication biases they influence social representations and bias the scientific evidence in favor of the view that ADHD is primarily caused by biological factors.

    2011-09-01

    Promotion of drugs for off-label use is newsworthy, because it is an illegal but all too common strategy used by pharmaceutical companies. The print media are an important source of information about coverage of off-label promotion of drugs and devices and can influence public perceptions of the practice. Print media coverage of off-label promotion during the years 1990-2008 were described and quantified. The primary themes and general tones relating to off-label promotion articles were evaluated. General concerns associated with off-label promotion and complaints about specific brand name drugs were also identified. Content analyses of the top 6 US newspapers were conducted over the period of 1990-2008 to analyze the media coverage given to off-label promotion of drugs and devices. Headlines and full text of articles were analyzed for primary themes and tones of the coverage. Intercoder reliability tests were performed on all the study variables. One hundred and one articles were identified meeting the study inclusion criteria. Coverage varied by newspaper. The Wall Street Journal had the most coverage on the topic (45%), and USA Today and Chicago Tribune had the least coverage (5%). Overall, most of the stories sampled were deemed to have a negative tone in coverage (77%), focusing mainly on lawsuits against drug companies for promoting their drugs for off-label uses. Pfizer's Neurontin(®) (Pfizer Inc., New York, NY 10017, USA) and Johnson & Johnson's Retin-A(®) (Orthoneutrogena, Los Angeles, CA 90045, USA) received the most media attention. The news media helps shape public understanding of promotional practices of pharmaceutical companies and their potential benefits and harms. This study suggests that print media coverage is generally negative about off-label promotion, focusing on legal actions taken against drug companies and the negative consequences of such promotional practices.

    2012-01-01

    Working memory retains information and makes it available for processing. People often need to hold several chunks of information available while concentrating on only one of them. This process requires selective attention to the contents of working memory. In this article we summarize evidence for both a broad focus of attention with a capacity of approximately four chunks and a narrow focus of attention that selects a single chunk at a time.

  9. Does Contralateral Delay Activity Reflect Working Memory Storage or the Current Focus of Spatial Attention within Visual Working Memory?

    Berggren, Nick; Eimer, Martin

    2016-12-01

    During the retention of visual information in working memory, event-related brain potentials show a sustained negativity over posterior visual regions contralateral to the side where memorized stimuli were presented. This contralateral delay activity (CDA) is generally believed to be a neural marker of working memory storage. In two experiments, we contrasted this storage account of the CDA with the alternative hypothesis that the CDA reflects the current focus of spatial attention on a subset of memorized items set up during the most recent encoding episode. We employed a sequential loading procedure where participants memorized four task-relevant items that were presented in two successive memory displays (M1 and M2). In both experiments, CDA components were initially elicited contralateral to task-relevant items in M1. Critically, the CDA switched polarity when M2 displays appeared on the opposite side. In line with the attentional activation account, these reversed CDA components exclusively reflected the number of items that were encoded from M2 displays, irrespective of how many M1 items were already held in working memory. On trials where M1 and M2 displays were presented on the same side and on trials where M2 displays appeared nonlaterally, CDA components elicited in the interval after M2 remained sensitive to a residual trace of M1 items, indicating that some activation of previously stored items was maintained across encoding episodes. These results challenge the hypothesis that CDA amplitudes directly reflect the total number of stored objects and suggest that the CDA is primarily sensitive to the activation of a subset of working memory representations within the current focus of spatial attention.

  10. A scoping review of research on complementary and alternative medicine (CAM) and the mass media: looking back, moving forward.

    2008-07-19

    The use of complementary and alternative medicine (CAM) has become more common in Western developed countries in recent years, as has media reporting on CAM and related issues. Correspondingly, media reports are a primary information source regarding decisions to use CAM. Research on CAM related media reports is becoming increasingly relevant and important; however, identifying key concepts to guide future research is problematic due to the dispersed nature of completed research in this field. A scoping review was conducted to: 1) determine the amount, focus and nature of research on CAM and the mass media; and 2) summarize and disseminate related research results. The main phases were: 1) searching for relevant studies; 2) selecting studies based on pre-defined inclusion criteria; 3) extracting data; and 4) collating, summarizing and reporting the results. Of 4,454 studies identified through various search strategies, 16 were relevant to our objectives and included in a final sample. CAM and media research has focused primarily on print media coverage of a range of CAM therapies, although only a few studies articulated differences within the range of therapies surveyed. Research has been developed through a variety of disciplinary perspectives, with a focus on representation research. The research reviewed suggests that journalists draw on a range of sources to prepare media reports, although most commonly they cite conventional (versus CAM) sources and personal anecdotes. The tone of media reports appears generally positive, which may be related to a lack of reporting on issues related to risk and safety. Finally, a variety of discourses within media representations of CAM are apparent that each appeal to a specific audience through resonance with their specific concerns. Research on CAM and the mass media spans multiple disciplines and strategies of inquiry; however, despite the diversity in approach, it is clear that issues related to production and reception

    The radioactive waste cleanup community has not effectively utilized its most powerful communications tool to inform the general public; the print and broadcast media. Environmental interest groups have known of the value of accessing the media for their message for years and have used it effectively. The radioactive waste cleanup community's efforts to date have not been focused on education of the media so that they in turn can inform the public of our cleanup mission. Their focus must be to learn of the importance of the media, develop training programs that train technical people in how to know and respond to the media's needs for information, and then incorporate that training into a comprehensive program of public information in which access to the media is a key communications tool. This paper discusses how media education and access is a cost-effective means of accomplishing community relations goals of public information and public participation in radioactive waste cleanup and has been effectively utilized at the Weldon Spring Site Remedial Action Project

  13. Exposure to violent and sexual media content undermines school performance in youth

    2015-03-01

    Full Text Available Background: Humans are hard-wired to pay attention to violent and sexual cues. Because humans have limited attention capacity, attention allocated to violent and sexual cues decreases attention that can be allocated to encoding important information in school. This study examined the effects of exposure to violent and sexual media on general school performance and Test of English as a Foreign Language (TOEFL scores in Turkish youth. Methods: The relationship between exposure to violent and sexual media on school performance was assessed in a sample of 1545 Turkish adolescents. Then, we compared the TOEFL scores of 143 Turkish boys aged 14 to 18 divided in 71 living in dormitories in which consumption of media was strictly regulated and 72 living at home. Results: A significant negative relationship was found between exposure to violent/sexual media and school success. The effects remained significant even after controlling for the total amount of media exposure. In addition, boys living in the dormitory in which consumption of media was strictly regulated outscored those living at home on the TOEFL post-test immediately after the end of the study, and on a delayed post-test one week later. Conclusions: Because there was no difference between boys living at home and those living in a dormitory on the pre-test, the post-test and delayed post-test differences cannot be attributed to initial differences in English language proficiency. These results suggest that exposure to violent and sexual media impairs adolescent school performance and foreign language memory.

  17. Endogenous attention modulates early selective attention in psychopathy: An ERP investigation.

    Science.gov (United States)

    Krusemark, Elizabeth A; Kiehl, Kent A; Newman, Joseph P

    2016-10-01

    Psychopathic individuals are prone to act on urges without adequate consideration of future consequences or the rights of other individuals. One interpretation of this behavior is that it reflects abnormal selective attention (i.e., a failure to process information that is incongruent with their primary focus of attention; Hiatt, Schmitt, & Newman, Neuropsychology, 18, 50-59, 2004). Unfortunately, it is unclear whether this selective attention abnormality reflects top-down endogenous influences, such as the strength or specificity of attention focus (i.e., top-down set) apart from other, more exogenous (bottom-up), effects on attention. To explore this question, we used an early visual event-related potential (N2pc) in combination with a modified visual search task designed to assess the effect of early endogenous (i.e., top-down) attention on the processing of set-congruent information. The task was administered to a sample of 70 incarcerated adult males, who were assigned to high, intermediate, and low psychopathy groups using Hare's Psychopathy Checklist-Revised (Hare, 2003). Based on the assumption that their failure to process set-incongruent information reflects the exaggerated effects of endogenous attention, we predicted that participants with high psychopathy scores would show an exaggerated N2pc response to set-congruent information. The results supported the hypothesis and provide novel electrophysiological evidence that psychopathy is associated with exaggerated endogenous attention effects during early stages of processing. Further research is needed to examine the implications of this finding for the well-established failure of psychopathic individuals to process set-incongruent information and inhibit inappropriate responses.

    Full Text Available The use of Internet-based sources of information for health surveillance applications has increased in recent years, as a greater share of social and media activity happens through online channels. The potential surveillance value in online sources of information about emergent health events include early warning, situational awareness, risk perception and evaluation of health messaging among others. The challenge in harnessing these sources of data is the vast number of potential sources to monitor and developing the tools to translate dynamic unstructured content into actionable information. In this paper we investigated the use of one social media outlet, Twitter, for surveillance of avian influenza risk in North America. We collected AI-related messages over a five-month period and compared these to official surveillance records of AI outbreaks. A fully automated data extraction and analysis pipeline was developed to acquire, structure, and analyze social media messages in an online context. Two methods of outbreak detection; a static threshold and a cumulative-sum dynamic threshold; based on a time series model of normal activity were evaluated for their ability to discern important time periods of AI-related messaging and media activity. Our findings show that peaks in activity were related to real-world events, with outbreaks in Nigeria, France and the USA receiving the most attention while those in China were less evident in the social media data. Topic models found themes related to specific AI events for the dynamic threshold method, while many for the static method were ambiguous. Further analyses of these data might focus on quantifying the bias in coverage and relation between outbreak characteristics and detectability in social media data. Finally, while the analyses here focused on broad themes and trends, there is likely additional value in developing methods for identifying low-frequency messages, operationalizing this

    Full Text Available Introduction: Informational exchanges around scientific communication activity have become increasingly dynamic in cyberspace, changing the practice of scientists and expanding the reach of research results that attain an increasingly significant online attention among different groups. Aim: To analyze whether altmetric data regarding online attention point to the existence of "virtual colleges" - composed of people from inside and outside the scientific community - around the scientific topic being discussed and shared in social media. Methodology: An exploratory pilot study, with analysis focused on the impact of the open access article with the highest altmetric indicator for the year 2015, as disclosed by Altmetric.com in its ranking "Top 100". The qualification of online attention is described by the most expressive media (Twitter and Facebook in a random sample (n = 10% on which content analysis was carried out and categorization of the types of interaction and characterization of social groups that interacted around the article. Results: The most common form of dissemination observed was retweeting on Twitter (62% and sharing on Facebook (45%, followed by "conclusive" (16% and 25% and “argumentative” (15% and 9.6% categories. The profile of the users responsible for the circulation of and discussion about the article indicates the prevalence of members from the general public. Conclusion: Altmetrics permit the tracking of the potentially more social and democratic impact assessment of scientific research, which becomes particularly evident for the case of articles featuring scientific research deemed to epitomise scientific controversies, the dimensions of which are played out in these “virtual colleges”.

    Full Text Available Few countries in the world have introduced media education into their curriculums. Montenegro became one of them in 2009, when “media literacy” was introduced as an optional subject for 16 and 17 year old students of Gymnasium high schools. This article presents the findings of the first and only research conducted so far on media education in Montenegro. It is a national case study which examines the potential of media education to change the school culture and accelerate education system reform towards embracing the new digital education paradigm in the future. The focus is on the results of research conducted through in-depth interviews with media literacy teachers all over the country. Despite the many challenges, all teachers identify the potential of media education to strengthen some of the key competences of the students and to improve their motivation and academic performance. They also identify potential to change positively school culture by transforming teachers into “cultural mediators” (Morcellini, 2007 and by supporting the formation of a “participative culture” (Jenkins & Kelley, 2013 in schools. This research recommends focusing education reform on spreading the media education pedagogy to the entire curriculum in order to embrace the new digital education paradigm in the future.

    Paul Hebert and colleagues first described DNA barcoding in 2003, which led to international efforts to promote and coordinate its use. Since its inception, DNA barcoding has generated considerable media coverage. We analysed whether this coverage reflected both the scientific and social mandates of international barcoding organizations. We searched newspaper databases to identify 900 English-language articles from 2003 to 2013. Coverage of the science of DNA barcoding was highly positive but lacked context for key topics. Coverage omissions pose challenges for public understanding of the science and applications of DNA barcoding; these included coverage of governance structures and issues related to the sharing of genetic resources across national borders. Our analysis provided insight into how barcoding communication efforts have translated into media coverage; more targeted communication efforts may focus media attention on previously omitted, but important topics. Our analysis is timely as the DNA barcoding community works to establish the International Society for the Barcode of Life.

    2012-01-01

    Research on visual attention has shown that Americans tend to focus more on focal objects of a scene while Asians attend to the surrounding environment. The panels of comic books – the narrative frames in sequential images – highlight aspects of a scene comparably to how attention becomes focused on parts of a spatial array. Thus, we compared panels from American and Japanese comics to explore cross-cultural cognition beyond behavioral experimentation by looking at the expressive mediums produced by individuals from these cultures. This study compared the panels of two genres of American comics (Independent and Mainstream comics) with mainstream Japanese “manga” to examine how different cultures and genres direct attention through the framing of figures and scenes in comic panels. Both genres of American comics focused on whole scenes as much as individual characters, while Japanese manga individuated characters and parts of scenes. We argue that this framing of space from American and Japanese comic books simulate a viewer’s integration of a visual scene, and is consistent with the research showing cross-cultural differences in the direction of attention.

    The current generation of young people indulges in more media multitasking behavior (e.g., instant messaging while watching videos) in their everyday lives than older generations. Concerns have been raised about how this might affect their attentional functioning, as previous studies have indicated that extensive media multitasking in everyday life may be associated with decreased attentional control. In the current study, 149 adolescents and young adults (aged 13-24years) performed speech-listening and reading tasks that required maintaining attention in the presence of distractor stimuli in the other modality or dividing attention between two concurrent tasks. Brain activity during task performance was measured using functional magnetic resonance imaging (fMRI). We studied the relationship between self-reported daily media multitasking (MMT), task performance and brain activity during task performance. The results showed that in the presence of distractor stimuli, a higher MMT score was associated with worse performance and increased brain activity in right prefrontal regions. The level of performance during divided attention did not depend on MMT. This suggests that daily media multitasking is associated with behavioral distractibility and increased recruitment of brain areas involved in attentional and inhibitory control, and that media multitasking in everyday life does not translate to performance benefits in multitasking in laboratory settings.

  9. The interplay of attention and emotion: top-down attention modulates amygdala activation in psychopathy.

    Psychopathic behavior has long been attributed to a fundamental deficit in fear that arises from impaired amygdala function. Growing evidence has demonstrated that fear-potentiated startle (FPS) and other psychopathy-related deficits are moderated by focus of attention, but to date, no work on adult psychopathy has examined attentional modulation of the amygdala or concomitant recruitment of relevant attention-related circuitry. Consistent with previous FPS findings, here we report that psychopathy-related differences in amygdala activation appear and disappear as a function of goal-directed attention. Specifically, decreased amygdala activity was observed in psychopathic offenders only when attention was engaged in an alternative goal-relevant task prior to presenting threat-relevant information. Under this condition, psychopaths also exhibited greater activation in selective-attention regions of the lateral prefrontal cortex (LPFC) than did nonpsychopaths, and this increased LPFC activation mediated psychopathy's association with decreased amygdala activation. In contrast, when explicitly attending to threat, amygdala activation did not differ in psychopaths and nonpsychopaths. This pattern of amygdala activation highlights the potential role of LPFC in mediating the failure of psychopathic individuals to process fear and other important information when it is peripheral to the primary focus of goal-directed attention.

    According to several conceptualizations of meditation, the interplay between brain systems associated to self-related processing, attention and executive control is crucial for meditative states and related traits. We used magnetoencephalography (MEG) to investigate such interplay in a highly selected group of “virtuoso” meditators (Theravada Buddhist monks), with long-term training in the two main meditation styles: focused attention (FA) and open monitoring (OM) meditation. Specifically, we investigated the differences between FA meditation, OM meditation and resting state in the coupling between the posterior cingulate cortex, core node of the Default Mode Network (DMN) implicated in mind wandering and self-related processing, and the whole brain, with a recently developed phase coherence approach. Our findings showed a state dependent coupling of posterior cingulate cortex (PCC) to nodes of the DMN and of the executive control brain network in the alpha frequency band (8–12 Hz), related to different attentional and cognitive control processes in FA and OM meditation, consistently with the putative role of alpha band synchronization in the functional mechanisms for attention and consciousness. The coupling of PCC with left medial prefrontal cortex (lmPFC) and superior frontal gyrus characterized the contrast between the two meditation styles in a way that correlated with meditation expertise. These correlations may be related to a higher mindful observing ability and a reduced identification with ongoing mental activity in more expert meditators. Notably, different styles of meditation and different meditation expertise appeared to modulate the dynamic balance between fronto-parietal (FP) and DMN networks. Our results support the idea that the interplay between the DMN and the FP network in the alpha band is crucial for the transition from resting state to different meditative states. PMID:25360102

    Full Text Available The analysis of the international legal framework for media in a real structural form is a challenge that needs to be scientifically proven because of the exceptional role of media in general and its constant and substantial impact on the democratic processes taking place in the world. If we analyze media through the eyes of history, we cannot ignore the impression of the exceptional importance of freedom of expression as the source and promoter of many substantive changes and valuable components in the overall functioning of social and political settings. In this regard, special attention is given to the impact of media on contemporary trends related to the EU integration process, the development of democracy and the rule of law. It particularly emphasizes the freedom of expression, respect for values and standards principles, human rights and freedoms. The purpose of this paper is to analyze the international legal framework for the media and to show the determination of the most important covenants which represent a source of media law containing rules for the creation and implementation of media freedom, the expressive quality of ideas and definitely and inevitably this paper stresses the power of the media.

  20. Do I Have My Attention? Speed of Processing Advantages for the Self-Face Are Not Driven by Automatic Attention Capture

    2014-01-01

    We respond more quickly to our own face than to other faces, but there is debate over whether this is connected to attention-grabbing properties of the self-face. In two experiments, we investigate whether the self-face selectively captures attention, and the attentional conditions under which this might occur. In both experiments, we examined whether different types of face (self, friend, stranger) provide differential levels of distraction when processing self, friend and stranger names. In Experiment 1, an image of a distractor face appeared centrally – inside the focus of attention – behind a target name, with the faces either upright or inverted. In Experiment 2, distractor faces appeared peripherally – outside the focus of attention – in the left or right visual field, or bilaterally. In both experiments, self-name recognition was faster than other name recognition, suggesting a self-referential processing advantage. The presence of the self-face did not cause more distraction in the naming task compared to other types of face, either when presented inside (Experiment 1) or outside (Experiment 2) the focus of attention. Distractor faces had different effects across the two experiments: when presented inside the focus of attention (Experiment 1), self and friend images facilitated self and friend naming, respectively. This was not true for stranger stimuli, suggesting that faces must be robustly represented to facilitate name recognition. When presented outside the focus of attention (Experiment 2), no facilitation occurred. Instead, we report an interesting distraction effect caused by friend faces when processing strangers’ names. We interpret this as a “social importance” effect, whereby we may be tuned to pick out and pay attention to familiar friend faces in a crowd. We conclude that any speed of processing advantages observed in the self-face processing literature are not driven by automatic attention capture. PMID:25338170

    Attention is the process by which information and selection occurs, the thalamus plays an important role in the selective attention of visual and auditory information. Selective attention is a conscious effort; however, it occurs subconsciously, as well. The lateral geniculate body (LGB) filters visual information before it reaches the cortex (bottom-up attention). The thalamic reticular nucleus (TRN) provides a strong inhibitory input to both the LGB and pulvinar. This regulation involves focusing a spotlight on important information, as well as inhibiting unnecessary background information. Behavioral contexts more strongly modulate activity of the TRN and pulvinar influencing feedforward and feedback information transmission between the frontal, temporal, parietal and occipital cortical areas (top-down attention). The medial geniculate body (MGB) filters auditory information the TRN inhibits the MGB. Attentional modulation occurring in the auditory pathway among the cochlea, cochlear nucleus, superior olivary complex, and inferior colliculus is more important than that of the MGB and TRN. We also discuss the attentional consequence of thalamic hemorrhage.

    Full Text Available The study analyses the media coverage practices concerning the “new diaspora”– the migration of the Romanian workforce in the countries of the European Union. Themain research question relates to how the media builds the image of the migrant, aswell as of the emerging forms in which the diaspora presents itself: is the diaspora a“distant” phenomenon (eventually recovered within a policy-media agenda or, on thecontrary, does the press propose varied and nuanced images of the migrant condition,approaching this theme as a public issue? In other words, what forms of “moraldistance” does the media build with respect to the Romanians who work abroad? Byapplying content analysis combined with discourse analysis with respect to two nationaldaily newspapers, the study shows that the press “defines” the diaspora as an abstractreality, in a sketchy presentation of idealized characters vs. negative characters. Assuch, the media establishes an imagery of compassion and benevolent attention – anexterior reality of the national public. The media discourse does not point out theparticularities of the diasporic experience in the context of the various types of mobility.

    Neurofeedback is a nonpharmacological treatment for attention-deficit hyperactivity disorder (ADHD). We propose that operant conditioning of electroencephalogram (EEG) in neurofeedback training aimed to mitigate inattention and low arousal in ADHD, will be accompanied by changes in EEG bands' relative power. Patients were 18 children diagnosed with ADHD. The neurofeedback protocol ("Focus/Alertness" by Peak Achievement Trainer) has a focused attention and alertness training mode. The neurofeedback protocol provides one for Focus and one for Alertness. This does not allow for collecting information regarding changes in specific EEG bands (delta, theta, alpha, low and high beta, and gamma) power within the 2 to 45 Hz range. Quantitative EEG analysis was completed on each of twelve 25-minute-long sessions using a custom-made MatLab application to determine the relative power of each of the aforementioned EEG bands throughout each session, and from the first session to the last session. Additional statistical analysis determined significant changes in relative power within sessions (from minute 1 to minute 25) and between sessions (from session 1 to session 12). Analysis was of relative power of theta, alpha, low and high beta, theta/alpha, theta/beta, and theta/low beta and theta/high beta ratios. Additional secondary measures of patients' post-neurofeedback outcomes were assessed, using an audiovisual selective attention test (IVA + Plus) and behavioral evaluation scores from the Aberrant Behavior Checklist. Analysis of data computed in the MatLab application, determined that theta/low beta and theta/alpha ratios decreased significantly from session 1 to session 12, and from minute 1 to minute 25 within sessions. The findings regarding EEG changes resulting from brain wave self-regulation training, along with behavioral evaluations, will help elucidate neural mechanisms of neurofeedback aimed to improve focused attention and alertness in ADHD.

    Full Text Available In the grasp of the media literacy studies, the concept of ‘participation’ has been able to gather a more significant attention and focus. In this regard, we could underline the 2009 European Union’s recommendations where it is possible to observe how participation is defined by this political organism in a framework of an active democracy alongside the intention to contribute into a healthier intercultural dialogue. In the same year, the EAVI (European Association for Viewers’ Interests has published also the Study for Assessment for Media Criteria Levels, as part of a research which understood participation as a social competence, a communicative skill in the top of the Media Literacy Criteria Levels’ pyramid. Acknowledging the importance of participation in a active citizenship, as it was put forward by Sherry Arnstein (1969 and profoundly related to the digital media literacy requirements (Peréz-Tornero, 2004, this research paper aims to draw the attention under the social representations of one group of participants in the audience discussion programme Banda Ampla, from the Catalan public television TV3, in Spain. Having in mind the motivations that have been able to conduct this group of citizens to participate live in the set, we have also been interested in evaluating the levels of adhesion in the participants to the technology possibilities to interact with media. In a fifty people sample, we will describe the production settings, through an ethnographic approach, based on a non-participation observation technique. In this inquiry we have also some data which allows us to think and question how media productions are actually opening the gates to let people partici- pate in their productions, such as in this programme broadcasted on 13th January 2011.

    Social comparison on social media has received increasing attention, but most research has focused on one type of social comparison and its psycho-emotional implications. Little is known about how different types of social comparison influence youth's identity development. Drawing on the theories of identity processing styles and social comparison, we examined how two different forms of social comparison on social media related to three identity processing styles, which in turn predicted youth's global self-esteem and identity clarity. We surveyed 219 college freshmen (M age  = 18.29; 74% female) once in the Fall and once in the Spring. Social comparison of ability on social media was related to concurrent diffuse-avoidant identity processing style, which predicted lower identity clarity months later. In contrast, social comparison of opinion on social media did not influence college freshmen's global self-esteem and identity clarity through identity processing styles. The findings clarified the implications of online social comparison for youth's identity development.

    This study investigates how characteristics of young adolescents' screen media use are associated with their BMI. By examining relationships between BMI and both time spent using each of 3 screen media and level of attention allocated to use, we sought to contribute to the understanding of mechanisms linking media use and obesity. We measured heights and weights of 91 13- to 15-year-olds and calculated their BMIs. Over 1 week, participants completed a weekday and a Saturday 24-hour time-use diary in which they reported the amount of time they spent using TV, computers, and video games. Participants carried handheld computers and responded to 4 to 7 random signals per day by completing onscreen questionnaires reporting activities to which they were paying primary, secondary, and tertiary attention. Higher proportions of primary attention to TV were positively associated with higher BMI. The difference between 25th and 75th percentiles of attention to TV corresponded to an estimated +2.4 BMI points. Time spent watching television was unrelated to BMI. Neither duration of use nor extent of attention paid to video games or computers was associated with BMI. These findings support the notion that attention to TV is a key element of the increased obesity risk associated with TV viewing. Mechanisms may include the influence of TV commercials on preferences for energy-dense, nutritionally questionable foods and/or eating while distracted by TV. Interventions that interrupt these processes may be effective in decreasing obesity among screen media users.

    2016-01-01

    The literature review regarding potential effects of screen media on cognitive development among children under 3 years old, is presented. In this article, cognitive aspects of development include acquisition of language, attention, learning and later school performance. The constant increase of children's access to television is noted, indicating that 60% of infants and toddlers watch TV regularly for 1-2 hours per day. The review included 40 articles and book chapters of significant such as Anderson, Barr, Christakis, Zimmerman, Meltzoff, Courage, Setliff, Troseth. The data was selected from electronic databases of scientific publications: Psychology & Behavioral Sciences Collection, Social Sciences Full Text (H.W. Wilson) and Humanities Full Text (H.W. Wilson) available in Poland. Cited articles provide evidence of the negative impact of exposure to television, media and video on the cognitive functioning of children under 3 years old. The potential impact of watching TV for difficulties in ability to focus attention appears as a core danger. Furthermore, studies suggest a possible connection between early exposure to television and ADHD as well as difficulties with language acquisition, learning and poorer school results.

  14. Cascading corruption news: explaining the bias of media attention to Brazil’s political scandals

    Mads Damgaard

    Full Text Available Abstract Through a content analysis of 8,800 news items and six months of front pages of three Brazilian newspapers, all dealing with corruption and political transgression, the present article documents the remarkable bias of media coverage toward corruption scandals. Said bias is examined as an informational phenomenon, arising from key systemic and commercial factors of Brazil’s news media: an information cascade of news on corruption formed, destabilizing the governing coalition and legitimizing the impeachment process of Dilma Rousseff. As this process gained momentum, questions of accountability were disregarded by the media, with harmful effects for democracy.

    Acute otitis media is the most common bacterial disease in children under five years; therefore, is one of the most common causes of pediatric consultation. Our objective was to determine the feasibility to consider this disease as a sentinel factor of medical attention. All the new cases of acute otitis media registered between 2008 and 2011 were collected and analyzed. Proportions, ratios, and incidence rates were determined. Also, the limits for proportions were calculated using mid P exact test. In children under five years, we observed 20 % of the cases of non-suppurative otitis media, and suppurative otitis media in 17 %. The reason for acute respiratory infection in relation to cases of otitis media in children of this age increased from 87:1 in 2008 to 53:1 in 2011. The reason of suppurative otitis media decreased in children under five years, even in 2009, when it was registered the highest number of new cases of acute respiratory infection. It was not feasible to determine if acute otitis media is a sentinel indicator; however, we could monitor medical attention indirectly.

    As a special form of contrast medium incidents, various reaction modes between iodinated contrast media and immunoglobulins are described. Theoretical explanations and typical examples are given for each of the four different possible action mechanisms. Diagnostic precautions are proposed in order to avoid unfavourable reactions especially with paraproteins. Special attention is drawn to the antigen-antibody like reaction between iodinated contrast media and IgM paraproteins. Some immunological criteria are recalled to attention, this type of reaction has to meet stringently. Only by this, misinterpretations of inevident conclusions from analogy can be prevented in future similar cases. (orig.) [de

  18. Mapping Controversies with Social Media: The Case for Symmetry

    Directory of Open Access Journals (Sweden)

    Noortje Marres

    2015-09-01

    Full Text Available This article assesses the usefulness for social media research of controversy analysis, an approach developed in Science and Technology Studies (STS and related fields. We propose that this approach can help to address an important methodological problem in social media research, namely, the tension between social media as resource for social research and as an empirical object in its own right. Initially developed for analyzing interactions between science, technology, and society, controversy analysis has in recent decades been implemented digitally to study public debates and issues dynamics online. A key feature of controversy analysis as a digital method, we argue, is that it enables a symmetrical approach to the study of media-technological dynamics and issue dynamics. It allows us to pay equal attention to the ways in which a digital platform like Twitter mediates public issues, and to how controversies mediate “social media” as an object of public attention. To sketch the contours of such a symmetrical approach, the article discusses examples from a recent social media research project in which we mapped issues of “privacy” and “surveillance” in the wake of the National Security Agency (NSA data leak by Edward Snowden in June 2013. Through a discussion of social media research practice, we then outline a symmetrical approach to analyzing controversy with social media. We conclude that the digital implementation of such an approach requires further exchanges between social media researchers and controversy analysts.

  19. Effects of Psychological Attention on Pronoun Comprehension

    Arnold, Jennifer E.; Lao, Shin-Yi C.

    2015-01-01

    Pronoun comprehension is facilitated for referents that are focused in the discourse context. Discourse focus has been described as a function of attention, especially shared attention, but few studies have explicitly tested this idea. Two experiments used an exogenous capture cue paradigm to demonstrate that listeners’ visual attention at the onset of a story influences their preferences during pronoun resolution later in the story. In both experiments trial-initial attention modulated listeners’ transitory biases while considering referents for the pronoun, whether it was in response to the capture cue or not. These biases even had a small influence on listeners’ final interpretation of the pronoun. These results provide independently-motivated evidence that the listener’s attention influences the on-line processes of pronoun comprehension. Trial-initial attentional shifts were made on the basis of non-shared, private information, demonstrating that attentional effects on pronoun comprehension are not restricted to shared attention among interlocutors.

  1. Primacy and recency effects as indices of the focus of attention

    Directory of Open Access Journals (Sweden)

    Alexandra B. Morrison

    2014-01-01

    Full Text Available Ongoing debate surrounds the capacity and characteristics of the focus of attention. The present study investigates whether a pattern of larger recency effects and smaller primacy effects reported in previous working memory studies is specific to task conditions used in those studies, or generalizes across manipulations of task-demand. Two experiments varied task-demands by requiring participants to remember lists of letters and to then respond to a subsequent two-item probe by indicating either the item that was presented later in the list (judgment of recency or the item was presented earlier (judgment of primacy. Analyses tested the prediction that a WM task emphasizing later items in a list (judgment of recency would encourage exaggerated recency effects and attenuated primacy effects, while a task emphasizing earlier items (judgment of primacy would encourage exaggerated primacy effects and attenuated recency effects. Behavioral results from two experiments confirmed this prediction. In contrast to past studies, fMRI contrasts revealed no brain regions where activity was significantly altered by the presence of recency items in the probe, for either task condition. However, presence of the primacy item in the probe significantly influenced activity in frontal lobe brain regions linked to active maintenance, but the location and direction of activation changes varied as a function of task instructions. In sum, two experiments demonstrate that the behavioral and neural signatures of WM, specifically related to primacy and recency effects, are dependent on task-demands. Findings are discussed as they inform models of the structure and capacity of WM.

    Full Text Available In this essay I argue that social media need to be understood as part of complex environments of communicative opportunities which I conceptualize as polymedia. This approach shifts our attention from social media as discrete platforms to the ways users navigate environments of affordances in order to manage their social relationships. Ethnography emerges as the most appropriate method to capture the relational dynamics that underpin social media practices within polymedia.

  3. Attention-like processes in insects.

    Attention is fundamentally important for sensory systems to focus on behaviourally relevant stimuli. It has therefore been an important field of study in human psychology and neuroscience. Primates, however, are not the only animals that might benefit from attention-like processes. Other animals, including insects, also have to use their senses and select one among many stimuli to forage, avoid predators and find mates. They have evolved different mechanisms to reduce the information processed by their brains to focus on only relevant stimuli. What are the mechanisms used by insects to selectively attend to visual and auditory stimuli? Do these attention-like mechanisms achieve the same functions as they do in primates? To investigate these questions, I use an established framework for investigating attention in non-human animals that proposes four fundamental components of attention: salience filters, competitive selection, top-down sensitivity control and working memory. I discuss evidence for each of these component processes in insects and compare the characteristics of these processes in insects to what we know from primates. Finally, I highlight important outstanding questions about insect attention that need to be addressed for us to understand the differences and similarities between vertebrate and insect attention. © 2016 The Author(s).

    2017-12-01

    The synchronization of loosely coupled chaotic systems has increasingly found applications to large networks of differential equations and to models of continuous media. These applications are at the core of the present Focus Issue. Synchronization between a system and its model, based on limited observations, gives a new perspective on data assimilation. Synchronization among different models of the same system defines a supermodel that can achieve partial consensus among models that otherwise disagree in several respects. Finally, novel methods of time series analysis permit a better description of synchronization in a system that is only observed partially and for a relatively short time. This Focus Issue discusses synchronization in extended systems or in components thereof, with particular attention to data assimilation, supermodeling, and their applications to various areas, from climate modeling to macroeconomics.

    Full Text Available In the text, from the angle of media philosophy, the relationship between the phenomenon of violence and entertainment in the age of the rule of media culture is re-examined. It first explores whether violence can be defined as violence at all when it comes to its presentation in the media; after the conclusion that in such cases it is always a matter of media transformed violence that goes into something else, the purpose of the massive appearance of violence in today’s media is investigated. In this context of inquiry, particular attention is drawn to the relationship between violence and entertainment that we encounter in the field of cinema and the video game industry.Asked why the entertainment industry uses violence in numerous media content, and whether violence is in itself fun, the answer is denied. Violence by itself can neither be fun; however, as a media product, it is highly profitable. That is why the world of entertainment today is flooded with violent content.

    Psychopathic behavior has long been attributed to a fundamental deficit in fear that arises from impaired amygdala function. Growing evidence demonstrates that fear potentiated startle (FPS) and other psychopathy-related deficits are moderated by focus of attention but, to date, no work on adult psychopathy has examined attentional modulation of the amygdala, or concomitant recruitment of relevant attention-related circuitry.

  9. Music and the Media, with Particular Attention to the Film

    Directory of Open Access Journals (Sweden)

    Fulvio Šuran

    2013-09-01

    Full Text Available This report has originated from the need to synthesize, without any claims, the big love between these two forms of art, music and the cinema, which together conceive a unique sublime art. The 20th century, attuned with the great cultural and social changes, witnesses the spreading of new forms of show, aimed to escape and entertainment, as well as new forms of music, while figurative art is changing, too. With reference to the spread of the media, the places and occasions of musical consumption are multiplied while musicians are acquiring new professional abilities. All this in the name of culture. But if we assume that culture is information and the media, then, for the social being, information becomes the very condition of survival. Thus, in this age dominated by the media, the struggle for survival is the struggle for mass information. On this point, it is sufficient to follow the relationship between MUSIC and the CINEMA in their historical evolution: from the soundtrack of silent films, to the music of talking films. However, it must be said that the relationship between music and the cinema, maybe because of the very nature of both, the languages, intrinsically progressive and rhythmic, have always been very close. A musical pattern, with all its possible nuances, can express events, feelings and intimate thoughts; silences accompanied by music reveal a character's state of mind much deeper than an hour of dialogues or voice off can do. On the other hand, the images of the film generate sensations that can express themselves completely only through music, which sometimes becomes an integral part of the plot of the film. The present report ends with my personal homage to recently died Ken Russell, one of the most original film directors, first rate «master» in the art of shocking dull minds, the artist who brought classical music to a completely new and large public: a big iconoclast able to transform marble busts into flesh and blood.

  11. When attention wanders: Pupillometric signatures of fluctuations in external attention.

    Konishi, Mahiko; Brown, Kevin; Battaglini, Luca; Smallwood, Jonathan

    2017-11-01

    Attention is not always directed to events in the external environment. On occasion our thoughts wander to people and places distant from the here and now. Sometimes, this lack of external attention can compromise ongoing task performance. In the current study we set out to understand the extent to which states of internal and external attention can be determined using pupillometry as an index of ongoing cognition. In two experiments we found that periods of slow responding were associated with elevations in the baseline pupil signal over three and a half seconds prior to a behavioural response. In the second experiment we found that unlike behavioural lapses, states of off-task thought, particularly those associated with a focus on the past and with an intrusive quality, were associated with reductions in the size of the pupil over the same window prior to the probe. These data show that both states of large and small baseline pupil size are linked to states when attention is not effectively focused on the external environment, although these states have different qualities. More generally, these findings illustrate that subjective and objective markers of task performance may not be equivalent and underscore the importance of developing objective indicators that can allow these different states to be understood.

    2007-01-01

    Full Text Available The present article is based on a qualitative study that aims to investigate the meanings attributed by adolescents to the violence in the media, especially on television, and the ways in which this group interacts with this media and appropriates its messages. The goal is to understand how the phenomenon of violence, mediated by television, is interpreted, incorporated or disapproved by adolescents in their everyday lives. Four focus groups with students from the seventh and eighth grades in São Gonçalo were conducted, in two public schools (one state and one municipal and two private schools (one of middle-class and one of lower-class students, totalizing 33 adolescents. It was concluded that one of the challenges for the field of public health is to improve its performance in the prevention of violence, taking into account the relevance of the media in constructing a discourse on violence. We call attention for the urgent need to understand the dimension and the psychological and cultural impact of violence in the media on Brazilian children and adolescents, once this phenomenon has been creating feeling of fear, anguish, and the seek for security. The positive aspect of the media as a potential partner in the education and promotion of children and adolescents' health is pointed out. The denaturalization of some notions of violence given by the media, and the construction of spaces in the media for the youngsters to express themselves are some ways for health promotion and violence prevention.

    2010-11-01

    Full Text Available Digital storytelling (DST has been widely used as a means of empowerment for marginalised voices across community-based projects worldwide. This paper discusses uses but also limitations of the practice in the context of a Melbourne-based youth media program for ‘youth at risk’ called YouthWorx. Based on our ongoing, long-term ethnographic research, we explore the cultural production of digital stories as a co-creative process that exposes a range of controversies to do with the politics of ‘voice’, genre’s communicative potential and ethical considerations. Concrete examples from YouthWorx’s pedagogical work serve to illustrate the values of self-expression (‘voice’, critical reflection and collaboration that form part of broader social transformations generated by these creative practices. The critique of DST practice offered here connects with existing studies concerned with the socially contextualised processes of media education, and the theoretical shift beyond ‘the right to speak’ towards ‘the right to be understood’ (Husband, 2009. The paper recommends more analytical attention be paid to a dynamic social process of learning (of media, interpersonal competencies and community-building, extending beyond the immediate DST situation, rather than narrowing the focus on end-result atomised media products.

The challenge for all of us is to work out what should be retained from this tradition, and what should be revised or rejected and to think about the concrete implications of what results from our reappraisal.

    Visual working memory (VWM) and attention have a number of features in common, but despite extensive research it is still unclear how the two interact. Can focused attention improve VWM precision? Can it protect VWM from interference? Here we used a partial-report, continuous-response orientation memory task to examine how attention and interference affect different aspects of VWM and how they interact with one another. Both attention and interference were orthogonally manipulated during the retention interval. Attention was manipulated by presenting informative retro-cues, whereas interference was manipulated by introducing a secondary interfering task. Mixture-model analyses revealed that retro-cues, compared to uninformative cues, improved all aspects of performance: Attention increased recall precision and decreased guessing rate and swap-errors (reporting a wrong item in memory). Similarly, performing a secondary task impaired all aspects of the VWM task. In particular, an interaction between retro-cue and secondary task interference was found primarily for swap-errors. Together these results suggest that both the quantity and quality of VWM representations are sensitive to attention cueing and interference modulations, and they highlight the role of attention in protecting the feature-location associations needed to access the correct items in memory.

  3. Smileys Without Borders. A Critique of Transboundary Interaction Between Politicians, Journalists and PR Practitioners on Social Media

    2018-01-01

    Full Text Available The purpose of the article is to contribute a critical theoretical understanding of cross-professional relations on social media, focusing on politicians, journalists and PR practitioners. It is well known that these professional groups establish personal and close relations in offline contexts, but more attention needs to be paid to the role of social media. Here, it is argued that, in the context of digital media use, semi-private chatting, humour, and mutual acknowledgement, including the use of likes, smileys, heart symbols, etc. are evidence of a 'neoliberalization' of cross-professional relations. The underlying idea is that the common practice of self-branding undermines representations of professional belonging and exacerbates the blurring of professional boundaries. The critical conceptualization of such 'transboundary' interaction between politicians, journalists and PR practitioners, which is guided by a cultural materialist approach, includes the presentation of examples deriving from the Swedish Twittersphere, and suggestions for empirical research.

    as for different age groups, the thesis shows that digital and especially social media use can be a strong driver of citizen participation. Besides looking at immediate mobilizing effects, the book sheds light on how digital media use may shape participation patterns through a long-term change in citizenship......The use of news media is regarded as a driver for citizens’ engagement with society and their political participation. But as news media use increasingly shifts to digital platforms, it is crucial to understand the interplay between a changing media environment and recent patterns of political...... participation. Against the background of citizens’ diverse possibilities for receiving political information and being politically active nowadays, the book focuses on the impact of digital media on political participation in Denmark. By examining this relationship in election- and non-election times as well...

  5. The public of media events

    2010-12-01

    Full Text Available This article focuses on the growing importance of large-scale events and their central role in a globalised media world in relation to public reactions and public involvement. The peculiar structure of such events requires a different understanding of mass communication and its audience. Therefore, the audience is further examined with regard to its impact on and inclusion in the media itself. Consequently, questions are raised as to how the public is incorporated, the form this inclusion takes and the effect that this has on the audience’s participation.The article examines different types of semantic inclusion, with a focus on emotional reactions towards three different media events: the Titanic disaster, the assassination of John F. Kennedy, and the death of Princess Diana.

  6. Prescribing practices amid the OxyContin crisis: examining the effect of print media coverage on opioid prescribing among physicians.

    2013-12-01

    The pain medication OxyContin (hereafter referred to as oxycodone extended release) has been the subject of sustained, and largely negative, media attention in recent years. We sought to determine whether media coverage of oxycodone extended release in North American newspapers has led to changes in prescribing of the drug in Nova Scotia, Canada. An interrupted time-series design examined the effect of media attention on physicians' monthly prescribing of opioids. The outcome measures were, for each physician, the monthly proportions of all opioids prescribed and the proportion of strong opioids prescribed that were for oxycodone extended release. The exposure of interest was media attention defined as the number of articles published each month in 27 North American newspapers. Variations in media effects by provider characteristics (specialty, prescribing volume, and region) were assessed. Within-provider changes in the prescribing of oxycodone extended release in Nova Scotia were observed, and they followed changes in media coverage. Oxycodone extended release prescribing rose steadily prior to receiving media attention. Following peak media attention in the United States, the prescribing of oxycodone extended release slowed. Likewise, following peak coverage in Canadian newspapers, the prescribing of oxycodone extended release declined. These patterns were observed across prescriber specialties and by prescriber volume, though the magnitude of change in prescribing varied. This study demonstrates that print media reporting of oxycodone extended release in North American newspapers, and its continued portrayal as a social problem, coincided with reductions in the prescribing of oxycodone extended release by physicians in Nova Scotia.

    To describe U.S. youth's access and exposure to the full array of media, as well as the social contexts in which media exposure occurs. A cross-sectional national random sample of 2065 adolescents aged 8 through 18 years, including oversamples of African-American and Hispanic youth, completed questionnaires about use of television, videotapes, movies, computers, video games, radio, compact discs, tape players, books, newspapers, and magazines. U.S. youngsters are immersed in media. Most households contain most media (computers and video game systems are the exception); the majority of youth have their own personal media. The average youth devotes 6 3/4 h to media; simultaneous use of multiple media increases exposure to 8 h of media messages daily. Overall, media exposure and exposure to individual media vary as a function of age, gender, race/ethnicity, and family socioeconomic level. Television remains the dominant medium. About one-half of the youth sampled uses a computer daily. A substantial proportion of children's and adolescents' media use occurs in the absence of parents. American youth devote more time to media than to any other waking activity, as much as one-third of each day. This demands increased parental attention and research into the effects of such extensive exposure.

    This is a thorough investigation into contemporary young people and their media life. The article conceptualizes a typology of media life, drawing on a theoretical body involving the sociology of generations, life course research, media life and individualization. This empirically derived typology...... makes a strong instrument for an understanding of the media life of the young, furnishing insights into how they have constructed their use of media. The investigation is based on a robust national survey with Swedes born 1994–2001, conducted in 2010, and focusing on four media: television, gaming......, the Internet and mobile devices. Two of the findings are particularly surprising. Firstly, the results reveal that the young generally lead heterogeneous media lives, varying with age and sex. Secondly, although some young people literarily live their life in media, there are also de facto young who live...

  10. Exploring the switching of the focus of attention within working memory: A combined event-related potential and behavioral study.

    Frenken, Marius; Berti, Stefan

    2018-04-01

    Working memory enables humans to maintain selected information for cognitive processes and ensures instant access to the memorized contents. Theories suggest that switching the focus of attention between items within working memory realizes the access. This is reflected in object-switching costs in response times when the item for the task processing is to be changed. Another correlate of attentional allocation in working memory is the P3a-component of the human event-related potential. The aim of this study was to demonstrate that switching of attention within working memory is a separable processing step. Participants completed a cued memory-updating task in which they were instructed to update one memory item at a time out of a memory list of four digits by applying a mathematical operation indicated by a target sign. The hypotheses predicted (1) prolonged updating times in switch (different item compared to previous trial) versus repetition trials (same item), (2) an influence of cues (valid/neutral) presented before the mathematical target on switching costs, and (3) that the P3a-component is more pronounced in the cue-target interval in the valid cue condition and more pronounced in the post-target interval in the neutral cue condition. A student's t-test verified the first hypothesis, repeated-measurement analyses of variance demonstrated that hypotheses 2 and 3 should be rejected. Results suggest that switching of attention within working memory could not be separated from further processing steps and retro-cue benefits are not due to a head start of retrieval as well as that switch costs represent internal processes.

    Evidence suggests that cognitive training interventions can improve older adults' cognitive performance. Successful training programs are adaptable and train multiple cognitive domains to target individual strengths and weaknesses. Computerized training programs are useful because they allow older adults to easily access training. This pilot study used an online attention training program, ATTENTION WORKOUT™, to enhance three aspects of attention- coordination , allocation , and selective focus -in community-dwelling older adults randomized to either an abbreviated (n=13) or an extended (n=17) practice training program over a 6-week period. Participants in the extended practice group significantly improved on selective focus reading distraction tasks with unrelated words (U=39.5; Z=-2.34; p =.02) and blanks (U=26.5; Z=-3.05; p =.002) as well as a matching attributes task (U=49.5; Z=-2.33; p =.02). The extended practice group significantly improved on three tasks of coordinating attention - radio-tuning (U=30; Z=-2.73; p =.01), circuit-breaker resetting (U=46; Z=-2.24; p =.03), and the combination of the two tasks (U=15; Z=-3.51; p attention training programs, like ATTENTION WORKOUT, can improve attention-related skills in community-dwelling older adults.

  12. Reporting an Unsettled Countryside The News Media and Rural Protests in Britain

    Directory of Open Access Journals (Sweden)

    Michael Woods

    2010-06-01

    Full Text Available Most analyses of the role of the media in shaping and reproducing popular dis-courses of rurality have focused on film, television drama and literature. Compa-ratively little attention has been directed towards the role of the news media in framing perceptions of contemporary rural issues through reportage and commen-tary. This paper examines the engagement of the news media with a series of rural protests that developed in Britain between 1997 and 2007 around issues such as hunting and farm incomes. The news media had been complicit in maintaining the previous discursive construct of the countryside as a settled and almost apolitical space, but the emergence of major rural protests forced a shift in the representation of rural life. News coverage of rural issues and rural protests increased with the adoption of a new discourse of the ”unsettled countryside”. In adjusting to shifting news values, the news media initially bought and reproduced the frames promoted by the major rural campaign group, the Countryside Alliance, including tropes of the ”countryside in crisis”, the ”countryside comes to town” and the ”countryside speaks out for liberty”. Over time, however, a more complex web of representations developed as the perspectives adopted by different media outlets diverged, informed by political ideology. As such, it is argued that the news media played a key role not in only in mediating public reception of rural protests, and thus modulating their political significance, but also in framing the rural protests for participants within the rural community, and as such contributing to the mobilisation of a politicised rural identity and an active rural citizenship.

  13. External Versus Two Different Internal Foci of Attention in Long-Distance Throwing.

    The present study examined the influence of attentional focus on performance during a long-distance throwing task. Twelve participants executed three maximum-effort, long-distance baseball throwing attempts in three focus conditions: internal focus on wrist flexion (wrist internal focus), internal focus on the separation between pelvis and upper torso orientations (torso internal focus), and external focus on the ball path (external focus). Compared with the external focus and torso internal focus conditions, performance was poorer in the wrist internal focus condition. Performances were not different in the torso internal and external focus conditions. In addition, attentional focus affected the release angle of the ball but not its initial velocity. Our results reveal that the body part targeted for internal focus of attention and the forcefulness of the motor activity can be as important to motor performance as whether the attention is internal or external.

    The ability of an animal to perform a task successfully is limited by the amount of attention being simultaneously focused on other activities. One way in which individuals might reduce the cost of divided attention is by preferentially focusing on the most beneficial tasks. In territorial animals where aggression is lower among familiar individuals, the decision to associate preferentially with familiar conspecifics may therefore confer advantages by allowing attention to be switched from ag...

  16. Understanding Social Media Logic

    2013-08-01

    Full Text Available Over the past decade, social media platforms have penetrated deeply into the mech­anics of everyday life, affecting people's informal interactions, as well as institutional structures and professional routines. Far from being neutral platforms for everyone, social media have changed the conditions and rules of social interaction. In this article, we examine the intricate dynamic between social media platforms, mass media, users, and social institutions by calling attention to social media logic—the norms, strategies, mechanisms, and economies—underpin­ning its dynamics. This logic will be considered in light of what has been identified as mass me­dia logic, which has helped spread the media's powerful discourse outside its institutional boundaries. Theorizing social media logic, we identify four grounding principles—programmabil­ity, popularity, connectivity, and datafication—and argue that these principles become increas­ingly entangled with mass media logic. The logic of social media, rooted in these grounding principles and strategies, is gradually invading all areas of public life. Besides print news and broadcasting, it also affects law and order, social activism, politics, and so forth. Therefore, its sustaining logic and widespread dissemination deserve to be scrutinized in detail in order to better understand its impact in various domains. Concentrating on the tactics and strategies at work in social media logic, we reassess the constellation of power relationships in which social practices unfold, raising questions such as: How does social media logic modify or enhance ex­isting mass media logic? And how is this new media logic exported beyond the boundaries of (social or mass media proper? The underlying principles, tactics, and strategies may be relat­ively simple to identify, but it is much harder to map the complex connections between plat­forms that distribute this logic: users that employ them, technologies that

    Cognitive-behavioral models highlight the conjoint roles of self-focused attention (SFA), post-event processing (PEP), and performance appraisals in the maintenance of social anxiety. SFA, PEP, and biased performance appraisals are related to social anxiety; however, limited research has examined how SFA affects information-processing following social events. The current study examined whether SFA affects the relationships between performance appraisals and PEP following a social event.. 137 participants with high (n = 72) or low (n = 65) social anxiety were randomly assigned to conditions of high SFA or low SFA while engaging in a standardized social performance. Subsequent performance appraisals and PEP were measured. Immediate performance appraisals were not affected by SFA. High levels of SFA led to a stronger, inverse relationship between immediate positive performance appraisals and subsequent negative PEP. High levels of SFA also led to a stronger, inverse relationship between negative PEP and changes in positive performance appraisals.. Future research should examine whether the current findings, which involved a standardized social performance event, extend to interaction events as well as in a clinical sample. These findings suggest that SFA affects the processing of positive information following a social performance event. SFA is particularly important for understanding how negative PEP undermines positive performance appraisals.. Published by Elsevier Ltd.

    Studies about health-related quality of life (HRQOL) in children with otitis media have primarily focused on short-term effects of the disease, and how treatment with insertion of ventilation tubes (VTs) affects the HRQOL. More knowledge is needed about how long-term HRQOL is associated with different factors like insertion of VT and use of antibiotics. We aimed to analyse HRQOL in children with otitis media 1 year after inclusion and to what extent insertion of VT, use of antibiotics, diagnoses, symptoms in the children, day-care attention, parental absence from work and parental smoking were associated with the long-term HRQOL in children with otitis media. A cohort study including 397 children was carried out. The children were followed for 13 months, and symptoms, HRQOL and so on were identified by means of questionnaires. HRQOL in children with otitis media was significantly improved after 13 months. The improvement of HRQOL was significantly lower for children with sleep problems compared with children without sleep problems. The improvement in HRQOL was significantly lower in children whose parents had been absent from work during the preceding 3 months due to the child' s otitis media compared with children with parents not being absent from their work. There were no statistically significant differences in the improvement of HRQOL in children who had received a VT during the follow-up period compared with children without a VT. HRQOL in children with otitis media was significantly improved after 13 months. The improvement in HRQOL was significantly lower for children with sleep problems. The improvement in HRQOL was significantly lower in children whose parents had been absent from work due to the child's otitis media. There were no statistically significant differences in the improvement of HRQOL in children who had received a VT during the follow-up period.

    Although a growing number of psychosocial health promotion interventions use the critical analysis of media to facilitate behavior change, no specific guidelines exist to assist researchers and practitioners in the selection and evaluation of culturally relevant media stimuli for intervention development. Mobilizing Our Voices for Empowerment is a critical consciousness-based health enhancement intervention for HIV-positive Black young gay/bisexual men that employs the critical analysis of popular media. In the process of developing and testing this intervention, feedback on media stimuli was collected from youth advisory board members (n = 8), focus group participants (n = 19), intervention participants (n = 40), and intervention facilitators (n = 6). A thematic analysis of qualitative data resulted in the identification of four key attributes of media stimuli and participants' responses to media stimuli that are important to consider when selecting and evaluating media stimuli for use in behavioral health interventions employing the critical analysis of media: comprehension, relevance, emotionality, and action. These four attributes are defined and presented as a framework for evaluating media, and adaptable tools are provided based on this framework to guide researchers and practitioners in the selection and evaluation of media for similar interventions.

    Full Text Available This article uses Twitter messages sent in May 2011 to study the ability of the so-called 15-M movement, a "connective"? movement, to place their demands on the media agenda and maintain control over their own discourse. The results show that the activists' discourse included many issues, although greatest attention was given to three: electoral and party systems, democracy and governance, and civil liberties. Moreover, the study reveals that the media covered all the movement's issues and that activists maintained their plural discourse throughout the protest. This article contributes to the literature on "connective" social movements, showing that in certain circumstances these movements have the capacity to determine media coverage.

    Media influences behaviour, especially of the young children and adolescents in various ways. The present study examined the media coverage of a judicial hanging and its immediate social effect. In a qualitative study the media coverage of a case of a judicial hanging was thoroughly discussed and the media influence, for over a period of ten weeks of the incident, in terms of suicide and copying of hanging among children, was collected and analysed. Eighteen cases were reported as an aftermath of this hanging: 1 suicide and 17 imitative hanging in children with 5 deaths. This report calls for attention that media should be cautious and responsible in presenting the news items that have potential social impact.

  11. Transculturality as a Perspective: Researching Media Cultures Comparatively

    Directory of Open Access Journals (Sweden)

    Andreas Hepp

    2009-01-01

    Full Text Available Most of the research on media cultures operates in a "national-territorial" frame. Media cultures are considered as national cultures and other forms of media culture (for example professional journalism cultures, diasporas, celebrity cultures etc. are not investigated in their "deterritorial" character. But it is exactly such deterritorial forms of media culture that are gaining relevance with the ongoing pace of media globalization: they therefore have to be placed in the focus of comparative media and communication research. Starting with this consideration, the article develops a transcultural perspective on researching media cultures. Within this perspective it becomes possible to conduct comparative research on (territorial national media cultures as well as on other (deterritorial forms of present media cultures, as this approach moves the processes of cultural construction and articulation into the focus of analysis. To arrive at a better understanding of this approach, "media cultures" are defined as translocal phenomena in their territorial as well as their deterritorial relations. Based on this, the "semantics" of a transcultural research perspective are outlined, which then makes it possible to formulate practical principles for carrying out comparative qualitative research within this framework.

    Directory of Open Access Journals (Sweden)

    Mikkel Fugl Eskjær

    2010-11-01

    Full Text Available Systems theoretical media research raises the question whether the mass media constitute a unified institution, or whether the media, due to their internal differences, should be considered individually and independent of each other. By inscribing the media in a general social theory, systems theory conceptualises the media as an autonomous functional system. This intention is most clearly illustrated by the efforts to identify a shared code for the entire media system. Based on the media theory of Niklas Luhmann, this paper offers a critical presentation of the code discussion within systems theoretical media research. The first part of the paper briefly introduces the systems theoretical notion of a code as well as Luhmann’s definition of the media system as organised and regulated by the code of information. The second part presents a number of alternative suggestions and definitions of the media system’s code, which both indicate the scope of systems theoretical media research, but also point to some of the limitations in the systems theoretical approach. In the last part, the paper takes a critical look at the systems theoretical code discussion by arguing that a too narrow focus on code definitions is blocking a more productive investigation of the conditions, evolution, and autonomy of the media system.

    Full Text Available Purpose: We propose and apply a simplified nowcasting model to understand the correlations between social attention and topic trends of scientific publications. Design/methodology/approach: First, topics are generated from the obesity corpus by using the latent Dirichlet allocation (LDA algorithm and time series of keyword search trends in Google Trends are obtained. We then establish the structural time series model using data from January 2004 to December 2012, and evaluate the model using data from January 2013. We employ a state-space model to separate different non-regression components in an observational time series (i.e. the tendency and the seasonality and apply the “spike and slab prior” and stepwise regression to analyze the correlations between the regression component and the social media attention. The two parts are combined using Markov-chain Monte Carlo sampling techniques to obtain our results. Findings: The results of our study show that (1 the number of publications on child obesity increases at a lower rate than that of diabetes publications; (2 the number of publication on a given topic may exhibit a relationship with the season or time of year; and (3 there exists a correlation between the number of publications on a given topic and its social media attention, i.e. the search frequency related to that topic as identified by Google Trends. We found that our model is also able to predict the number of publications related to a given topic. Research limitations: First, we study a correlation rather than causality between topics' trends and social media. As a result, the relationships might not be robust, so we cannot predict the future in the long run. Second, we cannot identify the reasons or conditions that are driving obesity topics to present such tendencies and seasonal patterns, so we might need to do “field” study in the future. Third, we need to improve the efficiency of our model by finding more efficient
