    We investigated familiarity and preference judgments of participants toward a novel musical system. We exposed participants to tone sequences generated from a novel pitch probability profile. Afterward, we either asked participants to identify more familiar or we asked participants to identify preferred tone sequences in a two-alternative forced-choice task. The task paired a tone sequence generated from the pitch probability profile they had been exposed to and a tone sequence generated from another pitch probability profile at three levels of distinctiveness. We found that participants identified tone sequences as more familiar if they were generated from the same pitch probability profile which they had been exposed to. However, participants did not prefer these tone sequences. We interpret this relationship between familiarity and preference to be consistent with an inverted U-shaped relationship between knowledge and affect. The fact that participants identified tone sequences as even more familiar if they were generated from the more distinctive (caricatured) version of the pitch probability profile which they had been exposed to suggests that the statistical learning of the pitch probability profile is involved in gaining of musical knowledge.

    This paper considers possible problems researchers might face when interpreting the results of studies that employ variants of the preference procedure. Infants show a tendency to shift their preference from familiar to novel stimuli with increasing exposure to the familiar stimulus, a behaviour that is exploited by the habituation paradigm. This…

    Two experiments assessed effects of color preference and brand-logo familiarity on recall performance. Exp. 1 explored the color preferences, using a forced-choice technique, of 189 women and 63 men, Taiwanese college students ages 18 to 20 years (M = 19.4, SD = 1.5). The sequence of the three most preferred colors was white, light blue, and black and of the three least preferred colors was light orange, dark violet, and dark brown. Exp. 2 investigated the effects of color preference based on the results of Exp. 1 and brand-logo familiarity on recall. A total of 27 women and 21 men, Taiwanese college students ages 18 to 20 years (M = 19.2, SD = 1.2) participated. They memorized a list of 24 logos (four logos shown in six colors) and then performed sequential recall. Analyses showed color preference significantly affected recall accuracy. Accuracy for high color preference was significantly greater than that for low preferences. Results showed no significant effects of brand-logo familiarity or sex on accuracy. In addition, the interactive effect of color preference and brand-logo familiarity on accuracy was significant. These results have implications for the design of brand logos to create and sustain memory of brand images.

    Understanding preference decision making is a challenging problem because the underlying process is often implicit and dependent on context, including past experience. There is evidence for both familiarity and novelty as critical factors for preference in adults and infants. To resolve this puzzling contradiction, we examined the cumulative effects of visual exposure in different object categories, including faces, natural scenes, and geometric figures, in a two-alternative preference task. The results show a clear segregation of preference across object categories, with familiarity preference dominant in faces and novelty preference dominant in natural scenes. No strong bias was observed in geometric figures. The effects were replicated even when images were converted to line drawings, inverted, or presented only briefly, and also when spatial frequency and contour distribution were controlled. The effects of exposure were reset by a blank of 1 wk or 3 wk. Thus, the category-specific segregation of familiarity and novelty preferences is based on quick visual categorization and cannot be caused by the difference in low-level visual features between object categories. Instead, it could be due either to different biological significances/attractiveness criteria across these categories, or to some other factors, such as differences in within-category variance and adaptive tuning of the perceptual system.

    Coca-Cola (Coke) and Pepsi are nearly identical in chemical composition, yet humans routinely display strong subjective preferences for one or the other. This simple observation raises the important question of how cultural messages combine with content to shape our perceptions; even to the point of modifying behavioral preferences for a primary reward like a sugared drink. We delivered Coke and Pepsi to human subjects in behavioral taste tests and also in passive experiments carried out during functional magnetic resonance imaging (fMRI). Two conditions were examined: (1) anonymous delivery of Coke and Pepsi and (2) brand-cued delivery of Coke and Pepsi. For the anonymous task, we report a consistent neural response in the ventromedial prefrontal cortex that correlated with subjects' behavioral preferences for these beverages. In the brand-cued experiment, brand knowledge for one of the drinks had a dramatic influence on expressed behavioral preferences and on the measured brain responses.

  6. Novelty vs. familiarity principles in preference decisions: Task-context of past experience matters

    Full Text Available Our preferences are shaped by past experience in many ways, but a systematic understanding of the factors is yet to be achieved. For example, studies of the mere exposure effect show that experience with an item leads to increased liking (familiarity preference, but the exact opposite tendency is found in other studies utilizing dishabituation (novelty preference. Recently, it has been found that image category affects whether familiarity or novelty preference emerges from repeated stimulus exposure (Park, Shimojo, and Shimojo, PNAS 2010. Faces elicited familiarity preference, but natural scenes elicited novelty preference. In their task, preference judgments were made throughout all exposures, raising the question of whether the task-context during exposure was involved. We adapt their paradigm, testing if passive exposure or objective judgment task-contexts lead to different results. Results showed that after passive viewing, familiar faces were preferred, but no preference bias in either direction was found with natural scenes, or with geometric figures (control. After exposure during the objective judgment task, familiar faces were preferred, novel natural scenes were preferred, and no preference bias was found with geometric figures. The overall results replicate the segregation of preference biases across object categories and suggest that the preference for familiar faces and novel natural scenes are modulated by task-context memory at different processing levels or selection involvement. Possible underlying mechanisms of the two types of preferences are discussed.

  7. Preferring familiar emotions: As you want (and like) it?

    Do people want to feel emotions that are familiar to them? In two studies, participants rated how much they typically felt various emotions (i.e., familiarity of the emotion) and how much they generally wanted to experience these emotions. We found that, in general, people wanted to feel pleasant emotions more than unpleasant emotions. However, for both pleasant and unpleasant emotions, people more (vs. less) familiar with an emotion also wanted to experience it more. Links between the familiarity of an emotion and wanting to experience that emotion were not explained by the concurrent experience of familiar emotions. Also, we show that although familiar emotions were also liked more, liking did not fully account for wanting familiar emotions. Finally, the familiarity of emotions mediated the links between trait affect and the emotions people wanted to feel. We propose that people are motivated to feel familiar emotions, in part, because of their instrumental value. PMID:23962316

  10. Future Time Perspective in Occupational Teams: Do Older Workers Prefer More Familiar Teams?

    Working in teams is quite popular across different industries and cultures. While some of these teams exist for longer time periods, other teams collaborate only for short periods and members switch into new teams after goals are accomplished. However, workers' preferences for joining a new team might vary in different ways. Based on Carstensen's socioemotional selectivity theory, we predict that emotionally meaningful teams are prioritized when occupational future time perspective (OFTP) is perceived as limited. Building and expanding on studies outside of the work context, we expected that older as compared to younger workers prefer more familiar teams, and that this effect is mediated by workers' OFTP. Moreover, we assumed that experimentally manipulated OFTP can change such team preferences. The hypotheses were tested in an online scenario study using three experimental conditions (within-person design). Four hundred and fifty-four workers (57% female, age M = 45.98, SD = 11.46) were asked to choose between a familiar and a new team in three consecutive trials: under an unspecified OFTP (baseline), under an expanded OFTP (amendment of retirement age), and under a restricted OFTP (insolvency of the current company). Whereas the baseline condition was always first, the order of the second and third conditions was randomized among participants. In the baseline condition, results showed the expected mediation effect of workers' OFTP on the relation between workers' age and preference for a familiar over a new team. Higher age was associated with more limited OFTP, which in turn was associated with higher preference for a familiar over a new team. Moreover, experimentally restricting OFTP increased preference for a familiar team over a new team regardless of workers' age, providing further evidence for the assumed causal processes and showing interesting avenues for practical interventions in occupational teams.

    The stress response has been well documented in past music therapy literature. However, hypometabolism, or the relaxation response, has received much less attention. Music therapists have long utilized various music-assisted relaxation techniques with both live and recorded music to elicit such a response. The ongoing proliferations of relaxation music through commercial media and the dire lack of evidence to support such claims warrant attention from healthcare professionals and music therapists. The purpose of these 3 studies was to investigate the correlational relationships between 12 psychophysical properties of music, preference, familiarity, and degree of perceived relaxation in music. Fourteen music therapists recommended and analyzed 30 selections of relaxation music. A group of 80 healthy adults then rated their familiarity, preference, and degree of perceived relaxation in the music. The analysis provided a detailed description of the intrinsic properties in music that were perceived to be relaxing by listeners. These properties included tempo, mode, harmonic, rhythmic, instrumental, and melodic complexities, timbre, vocalization/lyrics, pitch range, dynamic variations, and contour. In addition, music preference was highly correlated with listeners' perception of relaxation in music for both music therapists and healthy adults. The correlation between familiarity and degree of relaxation reached significance in the healthy adult group. Results from this study provided an in-depth operational definition of the intrinsic parameters in relaxation music and also highlighted the importance of preference and familiarity in eliciting the relaxation response.

    Full Text Available Introduction: The Family Smoking Prevention and Tobacco Control Act of 2009 allows the US FDA to regulate tobacco products, including the banning of characterizing flavors, such as fruit and candy, cigarettes. The availability of mint flavored snus may facilitate the use of the product if consumers find it more palatable with respect to taste, odor, pleasantness, and intensity. Methods: This study assessed product evaluation (PES, odor identification, odor intensity, and odor hedonics among 151 smokers enrolled in a clinical trial of snus substitution for cigarettes. Results: Far more participants selected Winterchill (N=110 than Robust (N=41, regardless of their menthol cigarette smoking status. Nicotine dependence was higher among those who selected Winterchill (4 vs 3 on Fagerstrom scale, p=0.017. Those who found Winterchill to be more satisfying, less aversive, and having a more intense, more pleasant odor than Robust were substantially more likely to select Winterchill for their one week trial. Conclusions: Findings indicate that subjective effect measures such as the PES and DEQ are capable of differentiating products in terms of flavor preference, and that smokers express a strong preference for mint flavored snus.

    Expectation of salient rewards and novelty seeking are processes implicated in substance use disorders but the neurobiological substrates underlying these associations are not well understood. To better understand the regional circuitry of novelty and reward preference, rats were conditioned to pair unique cues with bacon, an initially novel food, or chow, a familiar food. In the same animals, after training, cue-induced brain activity was measured, and the relationships between activity and preference for three rewards, the conditioned foods and ethanol (EtOH), were separately determined. Activity in response to the food paired cues was measured using brain glucose metabolism (BGluM). Rats favoring bacon-paired (BAP) cues had increased BGluM in mesocorticolimbic brain regions after exposure to these cues, while rats favoring chow-paired (CHP) cues showed relative deactivation in these regions. Rats exhibiting BAP cue-induced activation in prefrontal cortex (PFC) also consumed more EtOH while rats with cortical activation in response to CHP cues showed lower EtOH consumption. Additionally, long-term stable expression levels of PFC Grin2a, a subunit of the NMDA receptor, correlated with individual differences in EtOH preference insomuch that rats with high EtOH preference had enduringly low PFC Grin2a mRNA expression. No other glutamatergic, dopaminergic or endocannabinoid genes studied showed this relationship. Overall, these results suggest that natural variation in mesocorticolimbic sensitivity to reward-paired cues underlies behavioral preferences for and vulnerability to alcohol abuse, and support the notion of common neuronal circuits involved in food- and drug-seeking behavior. The findings also provide evidence that PFC NMDA-mediated glutamate signaling may modulate these associations. Published by Elsevier B.V.

    Oxytocin has been previously associated with social attachment behaviors in various species, however, most studies focused on partner preference in the socially-monogamous prairie vole. In these, oxytocin treatment was shown to promote partner preference, such that females receiving either central or pulsatile peripheral administration would spend more time with a familiar male. This behavioral outcome was blocked by oxytocin receptor antagonist treatment. The aim of the current study was to further explore the preference-inducing properties of oxytocin by examining its effects on object preference on ovariectomized female rats. In other words, we assessed whether these effects would apply to objects and if they would be persistent across species. Eight rats were infused with oxytocin into the left ventricle and object preference was assessed at two delays: 30min and 4h. At the 30min delay, oxytocin-treated animals showed preference for the familiar object, whereas saline-treated controls exhibited preference for the novel object. At the 4h delay, both groups showed novel-object preference. Our findings show that oxytocin modulates object preference in the female rat at a shorter delay, similar to the findings from partner-preference studies in the prairie vole, suggesting that the mechanisms driving object preference might be in part similar to those responsible for partner preference.

    Animals often rely on events in their environment that provide information (i.e. experience) to alter their future decision-making in ways that are presumed to be beneficial. Such experience-based learning, however, does not always lead to adaptive decision-making. In this study, we use the omnivorous harvestman Heteromitobates discolor to explore the role of past diet on subsequent food choice and survival. We first tested whether a short-term homogeneous diet (rotten crickets, fresh crickets or dog food) influenced subsequent food choice (rotten cricket versus fresh cricket). We next examine the impact of diet on survival. We found that following experience with a homogeneous cricket diet, adult harvestmen displayed a learned preference for familiar food, regardless of whether it was rotten or fresh crickets; individuals experiencing dog food were equally likely to choose rotten versus fresh crickets. We additionally found that individuals that ate rotten crickets suffered shorter survival than those that ate fresh crickets. Together, our results suggest that the diet an individual experiences can lead to maladaptive food preferences-preferences that ultimately result in reduced longevity. © 2016 The Author(s).

  18. Dogs don't always prefer their owners and can quickly form strong preferences for certain strangers over others.

    2017-11-01

    The unique relationship between dog and owner has been demonstrated in several experimental procedures, including tests in which dogs are left alone or with a stranger, tests of dogs' appeasement or social approach when petted by their owner or a stranger, and their ability to learn when taught by their owner or a stranger. In all cases, dogs responded differently to their owner, which has been referred to as a specific attachment, and likely a product of a prolonged history of reinforcement. In the current study, we used a concurrent choice paradigm in which dogs could interact with two people, both of whom provided the same petting interaction, to test whether owned dogs would prefer their owner over a stranger and whether the familiarity of the testing context would influence preference. We also investigated whether shelter and owned dogs tested with two strangers would show a preference between strangers and whether that preference would be similar in magnitude to any preference between the owner and stranger. Owned dogs preferred to interact with their owners when in an unfamiliar context, but allocated more time to the stranger in a familiar context. Both shelter and owned dogs tested with two strangers showed a magnitude of preference for one stranger over the other similar to owned dogs' preference for owners in an unfamiliar context. These results parallel what has been found in strange situation tests with owned dogs tested with their owners, but the strength of preference shown for one of two strangers indicates dogs can form a preference for one person quickly. © 2017 Society for the Experimental Analysis of Behavior.

    Aim of this study was to investigate the preferential looking behaviour, subsequent to a familiarization task (8-min) with a previously responsive or motionless face, before and after a sleep cycle. Moreover, the role of the active sleep in memory consolidation of the responsive or motionless faces was explored. Hypotheses were that the newborns undergoing a motionless familiarization will exhibit a novelty effect (preference for the novel face) whereas the newborns undergoing a responsive familiarization will show a familiarity effect (preference for the known face) before and after the sleep cycle; moreover, the amount of active sleep will be associated with the looking time at the known face after a sleep cycle. Forty-five healthy full-term newborns were randomly assigned to two groups (group 1: motionless-familiarization and group 2: responsive-familiarization); in both groups newborns were video-recorded during four post-familiarization face-preference tasks, two of them performed before and two after a sleep cycle. During the pre-sleep-trials, there was not a significant preference for one face in both groups. During the post-sleep trials, the newborns showed a clear preference for the novel face. This effect was more evident in group 1. Only in group 2 there was a significant positive correlation between the active sleep duration and the looking duration at the known-face during the post-sleep trials (r=0.41; p=0.040). Multiple regression confirmed that only in the group 2 the total duration of the active sleep was associated with the looking duration at the known-face during the post-sleep trials (Adjusted R 2 =0.13; β=0.41; t=2.2; p=0.040). Findings showed that in newborns the face representation can be recalled after a sleep cycle. Moreover, the amount of the active sleep predicted the post-sleep looking toward the known-face only in the newborns who interactively familiarized with the face. Copyright © 2017 Elsevier Inc.

  5. Closing your eyes to follow your heart: Avoiding information to protect a strong intuitive preference.

    2018-02-01

    Rationally, people should want to receive information that is costless and relevant for a decision. But people sometimes choose to remain ignorant. The current paper identifies intuitive-deliberative conflict as a driver of information avoidance. Moreover, we examine whether people avoid information not only to protect their feelings or experiences, but also to protect the decision itself. We predict that people avoid information that could encourage a more thoughtful, deliberative decision to make it easier to enact their intuitive preference. In Studies 1 and 2, people avoid learning the calories in a tempting dessert and compensation for a boring task to protect their preferences to eat the dessert and work on a more enjoyable task. The same people who want to avoid the information, however, use it when it is provided. In Studies 3-5, people decide whether to learn how much money they could earn by accepting an intuitively unappealing bet (that a sympathetic student performs poorly or that a hurricane hits a third-world country). Although intuitively unappealing, the bets are financially rational because they only have financial upside. If people avoid information in part to protect their intuitive preference, then avoidance should be greater when an intuitive preference is especially strong and when information could influence the decision. As predicted, avoidance is driven by the strength of the intuitive preference (Study 3) and, ironically, information avoidance is greater before a decision is made, when the information is decision relevant, than after, when the information is irrelevant for the decision (Studies 4 and 5).

    Full Text Available Understanding the factors that affect the host-feeding preferences of triatomine bugs is crucial for estimating transmission risks and predicting the effects of control tactics targeting domestic animals. We tested whether Triatoma infestans bugs prefer to feed on dogs vs. chickens and on dogs vs. cats and whether vector density modified host choices and other vital rates under natural conditions.Two host choice experiments were conducted in small caged huts with two rooms between which bugs could move freely. Matched pairs of dog-chicken (six and dog-cat (three were assigned randomly to two levels of vector abundance and exposed to starved bugs during three nights. Bloodmeals from 1,160 bugs were tested by a direct enzyme-linked immunosorbent assay.Conditional logistic regression showed that dogs were highly preferred over chickens or cats and that vector density modified host-feeding choices. The relative risk of a bug being blood-engorged increased significantly when it fed only on dog rather than chicken or cat. Bugs achieved higher post-exposure weight at higher vector densities and successive occasions, more so if they fed on a dog rather than on a cat.Our findings strongly refute the hypothesis that T. infestans prefers to blood-feed on chickens rather than dogs. An increase in dog or cat availability or accessibility will increase the rate of bug feeding on them and exert strong non-linear effects on R(0. When combined with between-dog heterogeneities in exposure, infection, and infectiousness, the strong bug preference for dogs can be exploited to target dogs in general, and even the specific individuals that account for most of the risk, with topical lotions or insecticide-impregnated collars to turn them into baited lethal traps or use them as transmission or infestation sentinels based on their immune response to Trypanosoma cruzi or bug salivary antigens.

  12. Familiarity adds to attractiveness in matters of siskin mate choice.

    2013-12-22

    There is currently considerable controversy in evolutionary ecology revolving around whether social familiarity brings attraction when a female chooses a mate. The topic of familiarity is significant because by avoiding or preferring familiar individuals as mates, the potential for local adaptation may be reduced or favoured. The topic becomes even more interesting if we simultaneously analyse preferences for familiarity and sexual ornaments, because when familiarity influences female mating preferences, this could very significantly affect the strength of sexual selection on male ornamentation. Here, we have used mate-choice experiments in siskins Carduelis spinus to analyse how familiarity and patterns of ornamentation (i.e. the size of wing patches) interact to influence mating success. Our results show that females clearly prefer familiar individuals when choosing between familiar and unfamiliar males with similar-sized wing patches. Furthermore, when females were given the choice between a highly ornamented unfamiliar male and a less ornamented familiar male, half of the females still preferred the socially familiar birds as mates. Our finding suggests that male familiarity may be as important as sexual ornaments in affecting female behaviour in mate choice. Given that the potential for local adaptation may be favoured by preferring familiar individuals as mates, social familiarity as a mate-choice criterion may become a potential area of fruitful research on sympatric speciation processes.

    Full Text Available Purpose: The purpose of this study was to investigate the existence of familiarity bias amongst individual investors in the South African stock market. Problem investigated: According to Warren Buffet, one needs to maintain emotional detachment if one wants to be a successful investor. However, recent research indicates that the perceptions of companies’ products and brands may influence individuals’ investment decisions in the stock market. This phenomenon implies that the investment decisions of individual investors are not purely based on firm fundamentals as suggested by traditional finance theories, but might be driven partly by the positive or negative attitude they have towards certain companies’ products and brands. The existence of familiarity bias amongst individual investors was investigated to determine if individuals prefer to invest in companies they are familiar with as opposed to unfamiliar companies. Methodology: A quantitative approach was followed. An online survey was used to show images of familiar and unfamiliar company brands to respondents, whereafter respondents were asked to indicate whether they will invest in the shares of the identified companies. The statistical analysis entailed descriptive statistics as well as one-way analyses of variance to test the stated hypotheses. Main findings: The results of this exploratory study indicate that investors do exhibit familiarity bias when choosing between different companies to invest in. Value of the research: The inclination of individual investors to invest in familiar corporate brands can have implications for the marketing industry, financial markets, the performance of companies as well as the investment performance of individual investors in the sense that it would seem that company brands could have an influence on investment decisions.

  19. Familiarity in Source Memory

    2012-01-01

    Familiarity and recollection are thought to be separate processes underlying recognition memory. Event-related potentials (ERPs) dissociate these processes, with an early (approximately 300–500 ms) frontal effect relating to familiarity (the FN400) and a later (500–800 ms) parietal old/new effect relating to recollection. It has been debated whether source information for a studied item (i.e., contextual associations from when the item was previously encountered) is only accessible through recollection, or whether familiarity can contribute to successful source recognition. It has been shown that familiarity can assist in perceptual source monitoring when the source attribute is an intrinsic property of the item (e.g., an object’s surface color), but few studies have examined its contribution to recognizing extrinsic source associations. Extrinsic source associations were examined in three experiments involving memory judgments for pictures of common objects. In Experiment 1, source information was spatial and results suggested that familiarity contributed to accurate source recognition: the FN400 ERP component showed a source accuracy effect, and source accuracy was above chance for items judged to only feel familiar. Source information in Experiment 2 was an extrinsic color association; source accuracy was at chance for familiar items and the FN400 did not differ between correct and incorrect source judgments. Experiment 3 replicated the results using a within-subjects manipulation of spatial vs. color source. Overall, the results suggest that familiarity’s contribution to extrinsic source monitoring depends on the type of source information being remembered. PMID:22789677

  20. Strong oviposition preference for Bt over non-Bt maize in Spodoptera frugiperda and its implications for the evolution of resistance.

    Transgenic crops expressing Bt toxins have substantial benefits for growers in terms of reduced synthetic insecticide inputs, area-wide pest management and yield. This valuable technology depends upon delaying the evolution of resistance. The 'high dose/refuge strategy', in which a refuge of non-Bt plants is planted in close proximity to the Bt crop, is the foundation of most existing resistance management. Most theoretical analyses of the high dose/refuge strategy assume random oviposition across refugia and Bt crops. In this study we examined oviposition and survival of Spodoptera frugiperda across conventional and Bt maize and explored the impact of oviposition behavior on the evolution of resistance in simulation models. Over six growing seasons oviposition rates per plant were higher in Bt crops than in refugia. The Cry1F Bt maize variety retained largely undamaged leaves, and oviposition preference was correlated with the level of feeding damage in the refuge. In simulation models, damage-avoiding oviposition accelerated the evolution of resistance and either led to requirements for larger refugia or undermined resistance management altogether. Since larval densities affected oviposition preferences, pest population dynamics affected resistance evolution: larger refugia were weakly beneficial for resistance management if they increased pest population sizes and the concomitant degree of leaf damage. Damaged host plants have reduced attractiveness to many insect pests, and crops expressing Bt toxins are generally less damaged than conventional counterparts. Resistance management strategies should take account of this behavior, as it has the potential to undermine the effectiveness of existing practice, especially in the tropics where many pests are polyvoltinous. Efforts to bring down total pest population sizes and/or increase the attractiveness of damaged conventional plants will have substantial benefits for slowing the evolution of resistance.

    At ripening initiation in red grapevine (Vitis vinifera) berries, the exocarp turns color from green to red and then to purple due to the accumulation and extent of methylation of anthocyanins. The accumulation of transcripts encoding an O-methyltransferase was recently shown to be closely correlated with the onset of ripening and the degree of blue/purple pigmentation in grapevine berries; however, the biochemical function of this gene has remained uncharacterized. In this study, an O-methyltransferase cDNA that showed a distinct expression pattern when compared to closely related sequences was expressed in Escherichia coli and enzyme assays were carried out with a broad array of anthocyanin and other flavonoid substrates. We demonstrate that this enzyme carries out 3',5'-O-methylation of anthocyanins and flavonol compounds in vitro, which are known to be present in grape berries, with a preference for glycosylated substrates. The highest relative specific activity for the enzyme was found with delphinidin 3-O-glucoside as substrate. The enzyme is not able to methylate flavan type skeletons with chiral centers, such as either catechins or dihydroquercetin. The enzyme showed negligible specific activity for caffeoyl-CoA, compared to flavonol and anthocyanin substrates. Phylogenetic analysis of the O-methyltransferase suggests that it may be a member of a distinct subclass of Type 2 bivalent metal-dependent S-adenosyl-methionine O-methyltransferases. (c) 2010.

    Long-term memory (LTM) can influence many aspects of short-term memory (STM), including increased STM span. However, it is unclear whether LTM enhances the quantitative or qualitative aspect of STM. That is, do we retain a larger number of representations or more precise representations in STM for familiar stimuli than unfamiliar stimuli? This study took advantage of participants' prior rich multimedia experience with Pokémon, without investing on laboratory training to examine how prior LTM influenced visual STM. In a Pokémon visual STM change detection task, participants remembered more first-generation Pokémon characters that they were more familiar with than recent-generation Pokémon characters that they were less familiar with. No significant difference in memory quality was found when quantitative and qualitative effects of LTM were isolated using receiver operating characteristic (ROC) analyses. Critically, these effects were absent in participants who were unfamiliar with first-generation Pokémon. Furthermore, several alternative interpretations were ruled out, including general video-gaming experience, subjective Pokémon preference, and verbal encoding. Together, these results demonstrated a strong link between prior stimulus familiarity in LTM and visual STM storage capacity.

    Full Text Available The importance of music in our daily life has given rise to an increased number of studies addressing the brain regions involved in its appreciation. Some of these studies controlled only for the familiarity of the stimuli, while others relied on pleasantness ratings, and others still on musical preferences. With a listening test and a functional magnetic resonance imaging (fMRI experiment, we wished to clarify the role of familiarity in the brain correlates of music appreciation by controlling, in the same study, for both familiarity and musical preferences. First, we conducted a listening test, in which participants rated the familiarity and liking of song excerpts from the pop/rock repertoire, allowing us to select a personalized set of stimuli per subject. Then, we used a passive listening paradigm in fMRI to study music appreciation in a naturalistic condition with increased ecological value. Brain activation data revealed that broad emotion-related limbic and paralimbic regions as well as the reward circuitry were significantly more active for familiar relative to unfamiliar music. Smaller regions in the cingulate cortex and frontal lobe, including the motor cortex and Broca's area, were found to be more active in response to liked music when compared to disliked one. Hence, familiarity seems to be a crucial factor in making the listeners emotionally engaged with music, as revealed by fMRI data.

    Even in multicultural nations interracial relationships and marriages are quite rare, one reflection of assortative mating. A relatively unexplored factor that could explain part of this effect is that people may find members of their own racial group more attractive than members of other groups. We tested whether there is an own-race preference in attractiveness judgments, and also examined the effect of familiarity by comparing the attractiveness ratings given by participants of different ancestral and geographic origins to faces of European, East Asian and African origin. We did not find a strong own-race bias in attractiveness judgments, but neither were the data consistent with familiarity, suggesting an important role for other factors determining the patterns of assortative mating observed.

    This study suggests that familiarity and novelty preferences in infant experimental tasks can in some instances be interpreted together as a single indicator of language advance. We provide evidence to support this idea based on our use of the auditory headturn preference paradigm to record responses to words likely to be either familiar or unfamiliar to infants. Fifty-nine 10-month-old infants were tested. The task elicited mixed preferences: familiarity (longer average looks to the words likely to be familiar to the infants), novelty (longer average looks to the words likely to be unfamiliar) and no-preference (similar-length of looks to both type of words). The infants who exhibited either a familiarity or a novelty response were more advanced on independent indices of phonetic advance than the infants who showed no preference. In addition, infants exhibiting novelty responses were more lexically advanced than either the infants who exhibited familiarity or those who showed no-preference. The results provide partial support for Hunter and Ames’ (1988) developmental model of attention in infancy and suggest caution when interpreting studies indexed to chronological age. PMID:27242624

Los tratamientos son paliativos; y el uso de antibióticos, en especial la tetraciclina, ha demostrando buenos resultados en su control. Este trabajo presenta tres casos clínicos de una familia afectada por NBE, donde se discuten los posibles diagnósticos diferenciales y conductas terapéuticas indicadas. Un paciente masculino de 52 años de edad acudió a la clínica aquejado de lesiones blancas bilaterales. El paciente notó las lesiones 30 años antes, sin lograr un diagnóstico final de las mismas. Después de la anamnesis y del examen clínico fue realizada una biopsia incisional. La reunión de los datos clínicos e histopatológicos llevó al diagnóstico de NBE. Se le solicitó al paciente que indagase entre sus familiares con respecto a lesiones semejantes. Se detectó que el hijo de 19 años y la hija de 25 eran portadores de placas blancas en la mucosa yugal. Como no había afectación estética, se optó por no intervenir en las lesiones. El nevus blanco esponjoso es una lesión genética que debe ser diferenciada de otras patologías localizadas y sistémicas importantes, que tienen repercusiones serias para el individuo. Como no hay un tratamiento curativo para el NBE, el papel del cirujano dentista es diagnosticar esta lesión, aclarar al paciente sobre la naturaleza benigna y autolimitante del NBE y si fuera necesario desde el punto de vista estético, aplicar diferentes modalidades terapéuticas.

    Canned whole peeled tomatoes are a premium tomato product; however, no information is available about the key intrinsic and extrinsic quality attributes perceived by consumers when buying this product. This research considered consumers differing in the level of familiarity with peeled tomatoes, that is, knowledge, frequency of consumption, and availability of this product, on 3 markets: Chile (low), The Netherlands (medium), and Italy (high). The perceptions and preferences of each group were studied using first focus groups and subsequently conjoint analysis in order to identify the key quality attributes leading their preferences for this product. Focus groups identified 7 intrinsic attributes (color, packing medium, tomato consistency, acidity level, sweetness level, extra ingredients, and intensity of product taste), and 5 extrinsic attributes (packaging material, product type, country of origin, brand, and label design). Significant variations according to the familiarity were found. The conjoint analyses showed that color of tomatoes was the most important intrinsic quality attribute for all groups, while packaging material was the most important extrinsic quality attribute for Chileans and Dutch, being a glass container or a can with easy open the preferred packaging for respective groups. In contrast, country of origin was the most important parameter for Italians. We concluded that intrinsic and extrinsic attributes were strongly influenced by the degree of familiarity with canned whole peeled tomatoes. © 2016 Institute of Food Technologists®.

    Recognition of the identity of familiar faces in conditions with poor visibility or over large changes in head angle, lighting and partial occlusion is far more accurate than recognition of unfamiliar faces in similar conditions. Here we used a visual search paradigm to test if one class of social cues transmitted by faces—direction of another's attention as conveyed by gaze direction and head orientation—is perceived more rapidly in personally familiar faces than in unfamiliar faces. We found a strong effect of familiarity on the detection of these social cues, suggesting that the times to process these signals in familiar faces are markedly faster than the corresponding processing times for unfamiliar faces. In the light of these new data, hypotheses on the organization of the visual system for processing faces are formulated and discussed. PMID:25228873

    Recognition of personally familiar faces is remarkably efficient, effortless and robust. We asked if feature-based face processing facilitates detection of familiar faces by testing the effect of face inversion on a visual search task for familiar and unfamiliar faces. Because face inversion disrupts configural and holistic face processing, we hypothesized that inversion would diminish the familiarity advantage to the extent that it is mediated by such processing. Subjects detected personally familiar and stranger target faces in arrays of two, four, or six face images. Subjects showed significant facilitation of personally familiar face detection for both upright and inverted faces. The effect of familiarity on target absent trials, which involved only rejection of unfamiliar face distractors, suggests that familiarity facilitates rejection of unfamiliar distractors as well as detection of familiar targets. The preserved familiarity effect for inverted faces suggests that facilitation of face detection afforded by familiarity reflects mostly feature-based processes. PMID:28582439

    The coordinated and synchronized movement of animals in groups often referred to as collective motion emerges through the interactions between individual animals within the group. Factors which affect these interactions have the potential to shape collective movement. One such factor is familiarity, or the tendency to bias behaviour towards individuals as a result of social recognition. We examined the effect of familiarity on the expression of collective motion in small shoals of female guppies ( Poecilia reticulata ). Groups comprising familiar individuals were more strongly polarized than groups of unfamiliar individuals, particularly when in novel surroundings. The ability to form more strongly polarized shoals potentially promotes information transfer and enhances the anti-predator benefits of grouping.

    Music perception involves complex brain functions. The relationship between music and brain such as cortical entrainment to periodic tune, periodic beat, and music have been well investigated. It has also been reported that the cerebral cortex responded more strongly to the periodic rhythm of unfamiliar music than to that of familiar music. However, previous works mainly used simple and artificial auditory stimuli like pure tone or beep. It is still unclear how the brain response is influenced by the familiarity of music. To address this issue, we analyzed electroencelphalogram (EEG) to investigate the relationship between cortical response and familiarity of music using melodies produced by piano sounds as simple natural stimuli. The cross-correlation function averaged across trials, channels, and participants showed two pronounced peaks at time lags around 70 and 140 ms. At the two peaks the magnitude of the cross-correlation values were significantly larger when listening to unfamiliar and scrambled music compared to those when listening to familiar music. Our findings suggest that the response to unfamiliar music is stronger than that to familiar music. One potential application of our findings would be the discrimination of listeners' familiarity with music, which provides an important tool for assessment of brain activity.

    Past research finds that monolingual and bilingual children prefer native speakers to individuals who speak in unfamiliar foreign languages or accents. Do children in bilingual contexts socially distinguish among familiar languages and accents and, if so, how do their social preferences based on language and accent compare? The current experiments tested whether 5- to 7-year-olds in two bilingual contexts in the United States demonstrate social preferences among the languages and accents that are present in their social environments. We compared children's preferences based on language (i.e., English vs. their other native language) and their preferences based on accent (i.e., English with a native accent vs. English with a non-native [yet familiar] accent). In Experiment 1, children attending a French immersion school demonstrated no preference between English and French speakers but preferred American-accented English to French-accented English. In Experiment 2, bilingual Korean American children demonstrated no preference between English and Korean speakers but preferred American-accented English to Korean-accented English. Across studies, bilingual children's preferences based on accent (i.e., American-accented English over French- or Korean-accented English) were not related to their own language dominance. These results suggest that children from diverse linguistic backgrounds demonstrate social preferences for native-accented speakers. Implications for understanding the potential relation between social reasoning and language acquisition are discussed. Copyright © 2017 Elsevier Inc. All rights reserved.

  8. A Familiar(ity Problem: Assessing the Impact of Prerequisites and Content Familiarity on Student Learning.

    Full Text Available Prerequisites are embedded in most STEM curricula. However, the assumption that the content presented in these courses will improve learning in later courses has not been verified. Because a direct comparison of performance between students with and without required prerequisites is logistically difficult to arrange in a randomized fashion, we developed a novel familiarity scale, and used this to determine whether concepts introduced in a prerequisite course improved student learning in a later course (in two biology disciplines. Exam questions in the latter courses were classified into three categories, based on the degree to which the tested concept had been taught in the prerequisite course. If content familiarity mattered, it would be expected that exam scores on topics covered in the prerequisite would be higher than scores on novel topics. We found this to be partially true for "Very Familiar" questions (concepts covered in depth in the prerequisite. However, scores for concepts only briefly discussed in the prerequisite ("Familiar" were indistinguishable from performance on topics that were "Not Familiar" (concepts only taught in the later course. These results imply that merely "covering" topics in a prerequisite course does not result in improved future performance, and that some topics may be able to removed from a course thereby freeing up class time. Our results may therefore support the implementation of student-centered teaching methods such as active learning, as the time-intensive nature of active learning has been cited as a barrier to its adoption. In addition, we propose that our familiarity system could be broadly utilized to aid in the assessment of the effectiveness of prerequisites.

    Full Text Available Vivimos en sociedades envejecidas. El aumento de la esperanza de vida y la disminución de la fecundidad conllevan un debilitamiento de las estructuras familiares tradicionales entre las diversas generaciones. Ha aumentado la diversidad en las formas familiares, valores, normas, y costumbres. La prolongación de la vida y la coexistencia de varias generaciones permite poder detentar durante más años los diversos estatus y roles familiares. A pesar de los cambios en las relaciones familiares, de la investigación existente se desprende que la familia sigue siendo una institución social fundamental en el apoyo a las personas que lo necesitan, y en cuyo seno todavía se sigue practicando el intercambio de bienes y servicios –como el cuidado, entre otros—entre las generaciones. Es la permanencia en las sociedades contemporáneas de la solidaridad familiar intergeneracional. En ese contexto se presentan diversos resultados derivados de la investigación europea Old Age and Autonomy: The Role of Social Services System and Intergenerational Family Solidarity.Ageing is a feature of modern societies. The increase in life expectancy, together with the decrease in fertility rates in Western societies, is leading to the weakening of traditional intergenerational family structures. The diversity in family forms, values, norms, and behaviours has increased. The coexistence of several generations allows family members to maintain longer the different family statuses and roles. Despite social changes in family relations, existing research shows that the family continues to be a fundamental social institution in the support of persons in need of it. Transfers of goods and services –including care- continues to be common practice within families, showing that intergenerational family solidarity remains a feature in contemporary societies.

    How do infants find the words in the tangle of speech that confronts them? The present study shows that by as early as 6 months of age, infants can already exploit highly familiar words-including, but not limited to, their own names-to segment and recognize adjoining, previously unfamiliar words from fluent speech. The head-turn preference procedure was used to familiarize babies with short passages in which a novel word was preceded by a familiar or a novel name. At test, babies recognized the word that followed the familiar name, but not the word that followed the novel name. This is the youngest age at which infants have been shown capable of segmenting fluent speech. Young infants have a powerful aid available to them for cracking the speech code. Their emerging familiarity with particular words, such as their own and other people's names, can provide initial anchors in the speech stream.

    Adults and young children prefer to affiliate with some individuals rather than others. Studies have shown that monolingual children show in-group biases for individuals who speak their native language without a foreign accent (Kinzler et al., 2007). Some studies have suggested that bilingual children are less influenced than monolinguals by language variety when attributing personality traits to different speakers (Anisfeld and Lambert, 1964), which could indicate that bilinguals have fewer in-group biases and perhaps greater social flexibility. However, no previous studies have compared monolingual and bilingual children's reactions to speakers with unfamiliar foreign accents. In the present study, we investigated the social preferences of 5-year-old English and French monolinguals and English-French bilinguals. Contrary to our predictions, both monolingual and bilingual preschoolers preferred to be friends with native-accented speakers over speakers who spoke their dominant language with an unfamiliar foreign accent. This result suggests that both monolingual and bilingual children have strong preferences for in-group members who use a familiar language variety, and that bilingualism does not lead to generalized social flexibility.

  14. Cross-cultural agreement in facial attractiveness preferences: the role of ethnicity and gender.

    Directory of Open Access Journals (Sweden)

    Vinet Coetzee

    Full Text Available Previous work showed high agreement in facial attractiveness preferences within and across cultures. The aims of the current study were twofold. First, we tested cross-cultural agreement in the attractiveness judgements of White Scottish and Black South African students for own- and other-ethnicity faces. Results showed significant agreement between White Scottish and Black South African observers' attractiveness judgements, providing further evidence of strong cross-cultural agreement in facial attractiveness preferences. Second, we tested whether cross-cultural agreement is influenced by the ethnicity and/or the gender of the target group. White Scottish and Black South African observers showed significantly higher agreement for Scottish than for African faces, presumably because both groups are familiar with White European facial features, but the Scottish group are less familiar with Black African facial features. Further work investigating this discordance in cross-cultural attractiveness preferences for African faces show that Black South African observers rely more heavily on colour cues when judging African female faces for attractiveness, while White Scottish observers rely more heavily on shape cues. Results also show higher cross-cultural agreement for female, compared to male faces, albeit not significantly higher. The findings shed new light on the factors that influence cross-cultural agreement in attractiveness preferences.

    2014-02-01

    The origin of the Western preference for consonance remains unresolved, with some suggesting that the preference is innate. In Experiments 1 and 2 of the present study, 6-month-old infants heard six different consonant/dissonant pairs of stimuli, including those tested in previous research. In contrast to the findings of others, infants in the present study failed to listen longer to consonant stimuli. After 3 minutes of exposure to consonant or dissonant stimuli in Experiment 3, 6-month-old infants listened longer to the familiar stimulus, whether consonant or dissonant. Our findings are inconsistent with innate preferences for consonant stimuli. Instead, the effect of short-term exposure is consistent with the view that familiarity underlies the origin of the Western preference for consonant intervals.

    Wide-ranging animals, such as birds, regularly traverse large areas of the landscape efficiently in the course of their local movement patterns, which raises fundamental questions about the cognitive mechanisms involved. By using precision global-positioning-system loggers, we show that homing pigeons (Columba livia) not only come to rely on highly stereotyped yet surprisingly inefficient routes within the local area but are attracted directly back to their individually preferred routes even when released from novel sites off-route. This precise route loyalty demonstrates a reliance on familiar landmarks throughout the flight, which was unexpected under current models of avian navigation. We discuss how visual landmarks may be encoded as waypoints within familiar route maps.

    The visual system is tuned for rapid detection of faces, with the fastest choice saccade to a face at 100ms. Familiar faces have a more robust representation than do unfamiliar faces, and are detected faster in the absence of awareness and with reduced attentional resources. Faces of family and close friends become familiar over a protracted period involving learning the unique visual appearance, including a view-invariant representation, as well as person knowledge. We investigated the effect of personal familiarity on the earliest stages of face processing by using a saccadic-choice task to measure how fast familiar face detection can happen. Subjects made correct and reliable saccades to familiar faces when unfamiliar faces were distractors at 180ms—very rapid saccades that are 30 to 70ms earlier than the earliest evoked potential modulated by familiarity. By contrast, accuracy of saccades to unfamiliar faces with familiar faces as distractors did not exceed chance. Saccades to faces with object distractors were even faster (110 to 120 ms) and equivalent for familiar and unfamiliar faces, indicating that familiarity does not affect ultra-rapid saccades. We propose that detectors of diagnostic facial features for familiar faces develop in visual cortices through learning and allow rapid detection that precedes explicit recognition of identity.

  7. Recollection- and familiarity-based decisions reflect memory strength

    2008-05-01

    Full Text Available We used event-related fMRI to investigate whether recollection- and familiarity-based memory judgments are modulated by the degree of visual similarity between old and new art paintings. Subjects performed a flower detection task, followed by a Remember/Know/New surprise memory test. The old paintings were randomly presented with new paintings, which were either visually similar or visually different. Consistent with our prediction, subjects were significantly faster and more accurate to reject new, visually different paintings than new, visually similar ones. The proportion of false alarms, namely remember and know responses to new paintings, was significantly reduced with decreased visual similarity. The retrieval task evoked activation in multiple visual, parietal and prefrontal regions, within which remember judgments elicited stronger activation than know judgments. New, visually different paintings evoked weaker activation than new, visually similar items in the intraparietal sulcus. Contrasting recollection with familiarity revealed activation predominantly within the precuneus, where the BOLD response elicited by recollection peaked significantly earlier than the BOLD response evoked by familiarity judgments. These findings suggest that successful memory retrieval of pictures is mediated by activation in a distributed cortical network, where memory strength is manifested by differential hemodynamic profiles. Recollection- and familiarity-based memory decisions may therefore reflect strong memories and weak memories, respectively.

  8. Sequential effects in preference decision: Prior preference assimilates current preference.

    Directory of Open Access Journals (Sweden)

    Seah Chang

    Full Text Available An important factor affecting preference formation is the context in which that preference decision takes place. The current research examined whether one's preference formed for a previously presented stimulus influences the processing of a subsequent preference decision, henceforth referred to as the preference sequence effect. Using a novel sequential rating/judgment paradigm, the present study demonstrated the presence of a preference sequence effect using artistic photographs and face stimuli: A neutral stimulus was preferred more following a preferable stimulus than a less preferable stimulus. Furthermore, a similar trend was found even when the potential influence of response bias was controlled. These results suggest that an assimilative sequential effect exists even when sequential judgments are made solely based on one's subjective feeling; preference formed for a preceding stimulus modulates preference for a subsequent stimulus. This implies the need for a consideration of trial sequence as a factor creating a psychological context affecting the subsequent preference decisions.

    Full Text Available Young children, in general, appear to have a strong drive to explore the environment in ways that reveal its underlying causal structure. But are they really attuned specifically to casual information in this quest for understanding, or do they show equal interest in other types of non-obvious information about the world? To answer this question, we introduced 20 three-year-old children to two puppets who were anxious to tell the child about a set of novel artifacts and animals. One puppet consistently described causal properties of the items while the other puppet consistently described carefully matched non-causal properties of the same items. After a familiarization period in which children learned which type of information to expect from each informant, children were given the opportunity to choose which they wanted to hear describe each of eight pictured test items. On average, children chose to hear from the informant that provided causal descriptions on 72% of the trials. This preference for causal information has important implications for explaining the role of conceptual information in supporting early learning and may suggest means for maximizing interest and motivation in young children.

    One of the most basic and person-specific affective responses to music is liking. The present investigation sought to determine whether liking was preserved during spontaneous auditory imagery. To this purpose, we inserted two-second silent intervals into liked and disliked songs, a method known to automatically recreate a mental image of these songs. Neural correlates of musical preference were measured by high-density electroencephalography in twenty subjects who had to listen to a set of five pre-selected unknown songs the same number of times for two weeks. Time frequency analysis of the two most liked and the two most disliked songs confirmed the presence of neural responses related to liking. At the beginning of silent intervals (400-900 ms and 1000-1300 ms), significant differences in theta activity were originating from the inferior frontal and superior temporal gyrus. These two brain structures are known to work together to process various aspects of music and are also activated when measuring liking while listening to music. At the end of silent intervals (1400-1900 ms), significant alpha activity differences originating from the insula were observed, whose exact role remains to be explored. Although exposure was controlled for liked and disliked songs, liked songs were rated as more familiar, underlying the strong relationship that exists between liking, exposure, and familiarity.

    Previous research documents the under-utilization of hospice services by minority ethnic groups, but less data exist for Asian and Hispanic Americans. It is unclear whether these low utilization rates are a result of attitudinal or information barriers, or both. To examine self-reported familiarity and attitudes toward hospice among Asian and Hispanic groups in ethnically diverse Queens County, NY. We surveyed diverse adults during health fairs, at senior centers, and church programs directed at ethnic populations. Respondents completed surveys in their preferred language: Spanish, Chinese (Mandarin), and Korean. Analysis of variance was used to compare continuous variables among language groups; Fisher's exact test compared categorical variables. A total of 604 community adults were surveyed: 99 Chinese, 349 Korean, 156 Spanish. Respondents were mostly female, average age 53 years. Familiarity with hospice varied significantly among the groups (P < 0.001) and was lower in the Hispanic (16%) and higher in the Chinese (45%) and Korean (56%) groups. Personal experiences with hospice were low (8-16%) in all groups. A majority (75-94%) responded they would share hospice information with loved ones, but the Hispanic group was significantly less likely to do so compared with Chinese and Korean Americans. Between 74 and 95% reported willingness to receive future information about hospice, but the Korean group was significantly less likely to want information. When surveyed in their preferred language, Asian and Hispanic adults reported variable levels of familiarity with hospice services. Most responded positively to receiving future information and would tell friends and family members about hospice. Copyright © 2015 American Academy of Hospice and Palliative Medicine.

    Full Text Available The mating system of the Taiwan field vole (Microtus kikuchii has been proposed to be monogamous. In monogamous animals, individuals should exhibit monogamy syndromes, such as little sexual dimorphism and strong pair bonding (a strong social preference for a familiar partner versus a strange one. In this study, we examined the effect of cohabitation on the partner preference. In a reciprocal experiment, all test individuals were cohabited with a heterosexual vole for 24 hr prior to the partner preference trials. We collected the feces of voles before and after the trials, and analyzed the concentration of fecal steroid hormones, including testosterone of males, progesterone and estradiol of females, and corticosterone of all voles. The results showed that the behaviors of focal voles were not influenced by the status (partner or stranger of stimulus vole. There was no significant relationship between steroid hormones and partner preference. Furthermore, the degree of sexual dimorphism in the Taiwan field vole was low, and similar to that of the monogamous prairie vole (M. ochrogaster. In light of this study and other recent findings, we propose that the mating system of the Taiwan field vole is not strictly monogamy, but flexible depending on environmental conditions.

  15. Prioritized Detection of Personally Familiar Faces

    We investigated whether personally familiar faces are preferentially processed in conditions of reduced attentional resources and in the absence of conscious awareness. In the first experiment, we used Rapid Serial Visual Presentation (RSVP) to test the susceptibility of familiar faces and faces of strangers to the attentional blink. In the second experiment, we used continuous flash interocular suppression to render stimuli invisible and measured face detection time for personally familiar faces as compared to faces of strangers. In both experiments we found an advantage for detection of personally familiar faces as compared to faces of strangers. Our data suggest that the identity of faces is processed with reduced attentional resources and even in the absence of awareness. Our results show that this facilitated processing of familiar faces cannot be attributed to detection of low-level visual features and that a learned unique configuration of facial features can influence preconscious perceptual processing.

    Greenberg, S N; Tai, J

    2001-12-01

    In the present study, we investigated whether patterns of letter detection for function and content words in texts are affected by the familiarity of the material being read. In Experiment 1, subjects searched for target letters in sentences that had been rehearsed prior to performing the letter detection on them as well as on unfamiliar sentences. In Experiment 2, subjects searched for target letters in highly familiar verses (e.g., nursery rhymes) and in unfamiliar sentences that were matched to the familiar verses. A disadvantage in letter detection for function as compared with content words consistently found with unfamiliar passages was reduced significantly with the familiar material in both experiments. Specifically, letter detection for content words grew worse in familiar text, but letter detection for function words showed a contrasting modest, though nonsignificant, improvement. The results are consistent with the proposition that in very familiar texts, parafoveal analysis permits the identification of generally less familiar content words. Simultaneously, the normal pattern of weighing the structure and content elements of text changes so that more fixations on function words occur than when one is reading unfamiliar texts.

    Human desire for sweet taste spans all ages, races, and cultures. Throughout evolution, sweetness has had a role in human nutrition, helping to orient feeding behavior toward foods providing both energy and essential nutrients. Infants and young children in particular base many of their food choices on familiarity and sweet taste. The low cost and ready availability of energy-containing sweeteners in the food supply has led to concerns that the rising consumption of added sugars is the driving force behind the obesity epidemic. Low-calorie sweeteners are one option for maintaining sweet taste while reducing the energy content of children's diets. However, their use has led to further concerns that dissociating sweetness from energy may disrupt the balance between taste response, appetite, and consumption patterns, especially during development. Further studies, preferably based on longitudinal cohorts, are needed to clarify the developmental trajectory of taste responses to low-calorie sweeteners and their potential impact on the diet quality of children and youth.

  19. Breeding dispersal in black-headed gull: the value of familiarity in a contrasted environment.

    1. Some species (e.g. migratory species with high movement ability) are unlikely to experience any physical cost when dispersing, at least at the landscape scale. In these species dispersal is nevertheless behaviourally constrained to avoid non-physical costs such as the loss of familiarity with the breeding environment, and these constraints can be maladaptive in a fast-changing environment. 2. We evaluated such constraints using multievent modelling of a 20-year capture-mark-recapture data set from a multisite population of black-headed gull (Chroicocephalus ridibundus). The population undertakes seasonal migrations that are very large compared with the size of the study area. 3. Distances between colonies appeared as a strong predictor of breeding adults' dispersal rates, confirming behavioural constraints on dispersal. In addition, birds that had recruited outside their colony of birth (natal dispersers) tended to return to their colony of birth later in life (long-term memory effect). 4. An attraction for larger colonies was also visible in breeding adult dispersal patterns. The fact that distance and memory still constrained dispersal although the largest colony provided higher breeding success indicated departures from the ideal-free distribution, probably linked with the lack of information about distant colonies. Moreover, the regional population apparently functioned as a meta-colony where individuals frequently bred in suboptimal-choice locations before being able to recruit in their preferred colony.

  4. Familiar face + novel face = familiar face? Representational bias in the perception of morphed faces in chimpanzees

    Yoshi-Taka Matsuda

    2016-08-01

    Full Text Available Highly social animals possess a well-developed ability to distinguish the faces of familiar from novel conspecifics to induce distinct behaviors for maintaining society. However, the behaviors of animals when they encounter ambiguous faces of familiar yet novel conspecifics, e.g., strangers with faces resembling known individuals, have not been well characterised. Using a morphing technique and preferential-looking paradigm, we address this question via the chimpanzee’s facial–recognition abilities. We presented eight subjects with three types of stimuli: (1 familiar faces, (2 novel faces and (3 intermediate morphed faces that were 50% familiar and 50% novel faces of conspecifics. We found that chimpanzees spent more time looking at novel faces and scanned novel faces more extensively than familiar or intermediate faces. Interestingly, chimpanzees looked at intermediate faces in a manner similar to familiar faces with regards to the fixation duration, fixation count, and saccade length for facial scanning, even though the participant was encountering the intermediate faces for the first time. We excluded the possibility that subjects merely detected and avoided traces of morphing in the intermediate faces. These findings suggest a bias for a feeling-of-familiarity that chimpanzees perceive familiarity with an intermediate face by detecting traces of a known individual, as 50% alternation is sufficient to perceive familiarity.

    To collate the self-reported assessment of familiarity with some aspects of managerial competencies on the part of some surgeons and their observations on the managerial environment of their health institutions and draw appropriate policy implications. Cross-sectional study using a structured questionnaire. The study was conducted during the 50th Annual Scientific Conference of the West African College of Surgeons, which was held in Calabar, Nigeria, from 6th to It 12th February 2010. One hundred and ten out of 150 surgeons who were attending the conference returned their filled questionnaires. Their familiarity with business and financial concepts was lacking on crucial ones related to marketing strategies. Respondent largely found the listed objections to advertisement of medical services as very appropriate. They preferred largely to interact with themselves in professional associations rather than with others in cross-cultural groupings. Funding (66.4%) and political/ethnic influences (43.9%) were rated as impacting very negatively on their health institutions, while the deployment of information communication technology to institutional processes was adjudged to be unsatisfactory. Most of the indices of core competencies in modern health leadership and management appeared deficient among our study participants and their health institutions managerial environments were equally deficient. We recommend for a well-focussed short time duration health management course for all physicians particularly specialists.

    Isometric multi-joint tests are considered reliable and have strong relationships with 1RM performance. However, limited evidence is available for the isometric squat in terms of effects of familiarization and reliability. This study aimed to assess, the effect of familiarization, stability reliability, determine the smallest detectible difference, and the correlation of the isometric squat test with 1RM squat performance. Thirty-six strength-trained participants volunteered to take part in this study. Following three familiarization sessions, test-retest reliability was evaluated with a 48-hour window between each time point. Isometric squat peak, net and relative force were assessed. Results showed three familiarizations were required, isometric squat had a high level of stability reliability and smallest detectible difference of 11% for peak and relative force. Isometric strength at a knee angle of ninety degrees had a strong significant relationship with 1RM squat performance. In conclusion, the isometric squat is a valid test to assess multi-joint strength and can discriminate between strong and weak 1RM squat performance. Changes greater than 11% in peak and relative isometric squat performance should be considered as meaningful in participants who are familiar with the test.

    In border region studies, the concept of (un)familiarity is applied in empirical studies of consumer culture across borders, illustrating how feelings of unfamiliarity can have an off-putting influence on cross-border interaction (e.g. because of dislike of or lack of attraction to the other side......) at the same time as it can be an incentive for people living at borders to cross them (e.g. to explore the exotic other side). The concepts explanatory scope has, thus, far responded to the normative claim that a borderless Europe encourages and increases mobility. However, in previous studies applying...... the concept of (un)familiarity, an explanatory problem remains concerning people's unarticulated and perhaps deeper reasons for mobility and lack thereof. This leaves a question mark as to why feelings of (un)familiarity occur in the first place as well as the actual degree to which they constitute barriers...

    Understanding public perceptions of biodiversity is essential to ensure continued support for conservation efforts. Despite this, insights remain scarce at broader spatial scales, mostly due to a lack of adequate methods for their assessment. The emergence of new technologies with global reach and high levels of participation provide exciting new opportunities to study the public visibility of biodiversity and the factors that drive it. Here, we use a measure of internet saliency to assess the national and international visibility of species within four taxa of Brazilian birds (toucans, hummingbirds, parrots and woodpeckers), and evaluate how much of this visibility can be explained by factors associated with familiarity, aesthetic appeal and conservation interest. Our results strongly indicate that familiarity (human population within the range of a species) is the most important factor driving internet saliency within Brazil, while aesthetic appeal (body size) best explains variation in international saliency. Endemism and conservation status of a species had small, but often negative, effects on either metric of internet saliency. While further studies are needed to evaluate the relationship between internet content and the cultural visibility of different species, our results strongly indicate that internet saliency can be considered as a broad proxy of cultural interest.

  15. Dogs’ attention towards humans depends on their relationship, not only on social familiarity

    Horn, Lisa; Range, Friederike; Huber, Ludwig

    2014-01-01

    Both in humans and non-human animals it has been shown that individuals attend more to those they have previously interacted with and/or that they are more closely associated with than to unfamiliar individuals. Whether this preference is mediated by mere social familiarity based on exposure or by the specific relationship between the two individuals, however, remains unclear. The domestic dog is an interesting subject in this line of research as it lives in the human environment and regularly interacts with numerous humans, yet it often has a particularly close relationship with its owner. Therefore, we investigated how long dogs (Canis familiaris) would attend to the actions of two familiar humans and one unfamiliar experimenter, while varying whether dogs had a close relationship with only one or both familiar humans. Our data provide evidence that social familiarity by itself cannot account for dogs’ increased attention towards their owners since they only attended more to those familiar humans with whom they also had a close relationship.

    There are few quantitative examinations of the extent to which dogs discriminate between familiar and unfamiliar persons. In our study we have investigated whether dogs show differential behaviour towards humans of different degrees of familiarity (owner, familiar person, unfamiliar person). Dogs and humans were observed in eight test situations: (1) Three-way strange situation test, (2) Calling in from food, (3) Obedience test, (4) Walking away, (5) Threatening approach, (6) Playful interaction, (7) Food inhibition test and (8) Manipulation of the dog's body. Dogs distinguished between the owner and the two other test partners in those tests which involved separation from the owner (Test 1, 4), were aversive for the dog (Test 5) or involved playing interaction (Test 6). Our results revealed that the owner cannot be replaced by a familiar person in situations provoking elevated anxiety and fear. In contrasts, dogs did not discriminate between the owner and the familiar person in those tests that were based on obedient behaviour or behaviour towards an assertive person (Tests 2, 3, 7 and 8). Dogs' former training experience reduced the difference between their behaviour towards the owner and the familiar person in situations requiring obedience but it did not mask it totally. The dogs' behaviour towards each of the humans participating in the tests was consistent all over the test series. In summary, dogs discriminated between their owner and the unfamiliar person and always preferred the owner to the unfamiliar person. However, the discrimination between the owner and the familiar person is context-specific. This article is part of a Special Issue entitled: Canine Behavior. Copyright © 2014 Elsevier B.V.

  17. Experience with adults shapes multisensory representation of social familiarity in the brain of a songbird.

    2012-01-01

    Social animals learn to perceive their social environment, and their social skills and preferences are thought to emerge from greater exposure to and hence familiarity with some social signals rather than others. Familiarity appears to be tightly linked to multisensory integration. The ability to differentiate and categorize familiar and unfamiliar individuals and to build a multisensory representation of known individuals emerges from successive social interactions, in particular with adult, experienced models. In different species, adults have been shown to shape the social behavior of young by promoting selective attention to multisensory cues. The question of what representation of known conspecifics adult-deprived animals may build therefore arises. Here we show that starlings raised with no experience with adults fail to develop a multisensory representation of familiar and unfamiliar starlings. Electrophysiological recordings of neuronal activity throughout the primary auditory area of these birds, while they were exposed to audio-only or audiovisual familiar and unfamiliar cues, showed that visual stimuli did, as in wild-caught starlings, modulate auditory responses but that, unlike what was observed in wild-caught birds, this modulation was not influenced by familiarity. Thus, adult-deprived starlings seem to fail to discriminate between familiar and unfamiliar individuals. This suggests that adults may shape multisensory representation of known individuals in the brain, possibly by focusing the young's attention on relevant, multisensory cues. Multisensory stimulation by experienced, adult models may thus be ubiquitously important for the development of social skills (and of the neural properties underlying such skills) in a variety of species.

  2. Familiarity Detection is an Intrinsic Property of Cortical Microcircuits with Bidirectional Synaptic Plasticity

    2017-01-01

    Abstract Humans instantly recognize a previously seen face as “familiar.” To deepen our understanding of familiarity-novelty detection, we simulated biologically plausible neural network models of generic cortical microcircuits consisting of spiking neurons with random recurrent synaptic connections. NMDA receptor (NMDAR)-dependent synaptic plasticity was implemented to allow for unsupervised learning and bidirectional modifications. Network spiking activity evoked by sensory inputs consisting of face images altered synaptic efficacy, which resulted in the network responding more strongly to a previously seen face than a novel face. Network size determined how many faces could be accurately recognized as familiar. When the simulated model became sufficiently complex in structure, multiple familiarity traces could be retained in the same network by forming partially-overlapping subnetworks that differ slightly from each other, thereby resulting in a high storage capacity. Fisher’s discriminant analysis was applied to identify critical neurons whose spiking activity predicted familiar input patterns. Intriguingly, as sensory exposure was prolonged, the selected critical neurons tended to appear at deeper layers of the network model, suggesting recruitment of additional circuits in the network for incremental information storage. We conclude that generic cortical microcircuits with bidirectional synaptic plasticity have an intrinsic ability to detect familiar inputs. This ability does not require a specialized wiring diagram or supervision and can therefore be expected to emerge naturally in developing cortical circuits. PMID:28534043

  7. The Role of Familiarity for Representations in Norm-Based Face Space.

    According to the norm-based version of the multidimensional face space model (nMDFS, Valentine, 1991), any given face and its corresponding anti-face (which deviates from the norm in exactly opposite direction as the original face) should be equidistant to a hypothetical prototype face (norm), such that by definition face and anti-face should bear the same level of perceived typicality. However, it has been argued that familiarity affects perceived typicality and that representations of familiar faces are qualitatively different (e.g., more robust and image-independent) from those for unfamiliar faces. Here we investigated the role of face familiarity for rated typicality, using two frequently used operationalisations of typicality (deviation-based: DEV), and distinctiveness (face in the crowd: FITC) for faces of celebrities and their corresponding anti-faces. We further assessed attractiveness, likeability and trustworthiness ratings of the stimuli, which are potentially related to typicality. For unfamiliar faces and their corresponding anti-faces, in line with the predictions of the nMDFS, our results demonstrate comparable levels of perceived typicality (DEV). In contrast, familiar faces were perceived much less typical than their anti-faces. Furthermore, familiar faces were rated higher than their anti-faces in distinctiveness, attractiveness, likability and trustworthiness. These findings suggest that familiarity strongly affects the distribution of facial representations in norm-based face space. Overall, our study suggests (1) that familiarity needs to be considered in studies of mental representations of faces, and (2) that familiarity, general distance-to-norm and more specific vector directions in face space make different and interactive contributions to different types of facial evaluations.

  11. Repetition priming affects guessing not familiarity

    Full Text Available Abstract Background The claim that recollection and familiarity based memory processes have distinct retrieval mechanisms is based partly on the observation that masked repetition and semantic priming influence estimates of familiarity derived from know responses but have no effect on estimates of recollection derived from remember responses. Close inspection of the experiments on which this claim is based reveal the effect size to be small, potentially the result of a type-2 error, and/or inflated due to participants not having the opportunity to report guesses. This paper re-evaluates these claims by attempting a partial replication of two such Experiments. Methods In Experiment 1 participants made remember, know, and guess responses following primed and unprimed target words. In Experiment 2 participants made sure, unsure, and guess following primed and unprimed target words. Results In Experiment 1 the repetition priming effect occurred only for guess responses and only for unstudied items. In Experiment 2 the priming effect occurred for both unsure and guess responses, but again only for unstudied items. Conclusion The data are consistent with the view that remembering and knowing do not correspond to confidence ratings; and suggest that contrary to earlier findings, recollection and familiarity do not differ in retrieval mechanisms. As such the effects of repetition priming on subjective reports of remembering should not be cited as evidence for the distinction between recollection and familiarity based memory processes.

  13. Facelock: familiarity-based graphical authentication

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available Authentication codes such as passwords and PIN numbers are widely used to control access to resources. One major drawback of these codes is that they are difficult to remember. Account holders are often faced with a choice between forgetting a code, which can be inconvenient, or writing it down, which compromises security. In two studies, we test a new knowledge-based authentication method that does not impose memory load on the user. Psychological research on face recognition has revealed an important distinction between familiar and unfamiliar face perception: When a face is familiar to the observer, it can be identified across a wide range of images. However, when the face is unfamiliar, generalisation across images is poor. This contrast can be used as the basis for a personalised ‘facelock’, in which authentication succeeds or fails based on image-invariant recognition of faces that are familiar to the account holder. In Study 1, account holders authenticated easily by detecting familiar targets among other faces (97.5% success rate, even after a one-year delay (86.1% success rate. Zero-acquaintance attackers were reduced to guessing (<1% success rate. Even personal attackers who knew the account holder well were rarely able to authenticate (6.6% success rate. In Study 2, we found that shoulder-surfing attacks by strangers could be defeated by presenting different photos of the same target faces in observed and attacked grids (1.9% success rate. Our findings suggest that the contrast between familiar and unfamiliar face recognition may be useful for developers of graphical authentication systems.

    Common mistakes are frequent in sensory evaluation of meats and meat products. Conceptual confusion is often observed in triangular tests when add-on questions are included in the testing procedures, and when descriptive and hedonic scales are mixed in profiling exercises. Similar consumer responses are often recorded from trained, and thus biased, panels. Preference for meats seems to be most strongly affected by changes in colour/appearance and texture, and to a lesser extent by changes in flavour (that is when off-flavours are not present). It is difficult to generalise as to whether appearance/colour attributes or texture attributes are the most important. A simplified model for texture understanding is suggested, where water/fat perception and structure perception (described by juiciness and tenderness) are orthogonal phenomena and where most other textural attributes can be explained by this structure.

    Full Text Available ObjectiveFamiliarity is a subjective sensation that contributes to person recognition. This process is described as an emotion-based memory-trace of previous meetings and could be disrupted in schizophrenia. Consequently, familiarity disorders could be involved in the impaired social interactions observed in patients with schizophrenia. Previous studies have primarily focused on famous people recognition. Our aim was to identify underlying features, such as emotional disturbances, that may contribute to familiarity disorders in schizophrenia. We hypothesize that patients with familiarity disorders will exhibit a lack of familiarity that could be detected by a flattened skin conductance response (SCR.MethodThe SCR was recorded to test the hypothesis that emotional reactivity disturbances occur in patients with schizophrenia during the categorization of specific familiar, famous and unknown faces as male or female. Forty-eight subjects were divided into the following 3 matched groups with 16 subjects per group: control subjects, schizophrenic people with familiarity disorder, and schizophrenic people without familiarity disorders.ResultsEmotional arousal is reflected by the skin conductance measures. The control subjects and the patients without familiarity disorders experienced a differential emotional response to the specific familiar faces compared with that to the unknown faces. Nevertheless, overall, the schizophrenic patients without familiarity disorders showed a weaker response across conditions compared with the control subjects. In contrast, the patients with familiarity disorders did not show any significant differences in their emotional response to the faces, regardless of the condition.ConclusionOnly patients with familiarity disorders fail to exhibit a difference in emotional response between familiar and non-familiar faces. These patients likely emotionally process familiar faces similarly to unknown faces. Hence, the lower

    The sensory-chemical profiles of Finnish honeys (labeled as buckwheat, cloudberry-bog, lingonberry, sweet clover, willowherb and multifloral honeys) were investigated using a multi-analytical approach. The sensory test (untrained panel, n = 62) was based on scaling and check-all-that-apply (CATA) methods accompanied with questions on preference and usage of honey. The results were correlated with corresponding profiles of odor-active compounds, determined using gas chromatography coupled with mass spectrometry/olfactometry (GC-MS/O). Botanical origins and chemical compositions including sugars were evaluated using NMR spectroscopy. A total of 73 odor-active compounds were listed based on GC-O. Sweet and mild honeys with familiar sensory properties were preferred by the panelists (PCA, R 2 X(1) = 0.7) while buckwheat and cloudberry-bog honeys with strong odor, flavor and color were regarded as unfamiliar and unpleasant. The data will give the honey industry novel information on honey properties in relation to the botanical origin, and consumer preference. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2014-12-01

    Heuristics involve the ability to utilize memory to make quick judgments by exploiting fundamental cognitive abilities. In the current study we investigated the memory processes that contribute to the recognition heuristic and the fluency heuristic, which are both presumed to capitalize on the byproducts of memory to make quick decisions. In Experiment 1, we used a city-size comparison task while recording event-related potentials (ERPs) to investigate the potential contributions of familiarity and recollection to the 2 heuristics. ERPs were markedly different for recognition heuristic-based decisions and fluency heuristic-based decisions, suggesting a role for familiarity in the recognition heuristic and recollection in the fluency heuristic. In Experiment 2, we coupled the same city-size comparison task with measures of subjective preexperimental memory for each stimulus in the task. Although previous literature suggests the fluency heuristic relies on recognition speed alone, our results suggest differential contributions of recognition speed and recollected knowledge to these decisions, whereas the recognition heuristic relies on familiarity. Based on these results, we created a new theoretical framework that explains decisions attributed to both heuristics based on the underlying memory associated with the choice options.

    Analysis of data from the American Life Panel shows that in the presidential election of 2008 and in multiple statewide elections in 2010, citizens exhibited large differences in their expectations of election outcomes. Expectations were strongly positively associated with candidate preferences, persons tending to believe that their preferred candidate is more likely to win the election. Committed supporters of opposing candidates regularly differed by 20–30% in their assessments of the likelihood that each candidate would win. These findings contribute evidence on the false consensus effect, the empirical regularity that own preferences tend to be positively associated with perceptions of social preferences. We used unique measures of preferences and perceptions that enabled respondents to express uncertainty flexibly. We studied a setting that would a priori seem inhospitable to false consensus—one where persons have little private information on social preferences but substantial common knowledge provided by media reports of election polls.

    The distribution of weak and strong non-linear feeding interactions (i.e., functional responses) across the links of complex food webs is critically important for their stability. While empirical advances have unravelled constraints on single-prey functional responses, their validity in the context of complex food webs where most predators have multiple prey remain uncertain. In this study, we present conceptual evidence for the invalidity of strictly density-dependent consumption as the null model in multi-prey experiments. Instead, we employ two-prey functional responses parameterised with allometric scaling relationships of the functional response parameters that were derived from a previous single-prey functional response study as novel null models. Our experiments included predators of different sizes from two taxonomical groups (wolf spiders and ground beetles) simultaneously preying on one small and one large prey species. We define compliance with the null model predictions (based on two independent single-prey functional responses) as passive preferences or passive switching, and deviations from the null model as active preferences or active switching. Our results indicate active and passive preferences for the larger prey by predators that are at least twice the size of the larger prey. Moreover, our approach revealed that active preferences increased significantly with the predator-prey body-mass ratio. Together with prior allometric scaling relationships of functional response parameters, this preference allometry may allow estimating the distribution of functional response parameters across the myriads of interactions in natural ecosystems.

    Why do we like the music we do? Research has shown that musical preferences and personality are linked, yet little is known about other influences on preferences such as cognitive styles. To address this gap, we investigated how individual differences in musical preferences are explained by the empathizing-systemizing (E-S) theory. Study 1 examined the links between empathy and musical preferences across four samples. By reporting their preferential reactions to musical stimuli, samples 1 and 2 (Ns = 2,178 and 891) indicated their preferences for music from 26 different genres, and samples 3 and 4 (Ns = 747 and 320) indicated their preferences for music from only a single genre (rock or jazz). Results across samples showed that empathy levels are linked to preferences even within genres and account for significant proportions of variance in preferences over and above personality traits for various music-preference dimensions. Study 2 (N = 353) replicated and extended these findings by investigating how musical preferences are differentiated by E-S cognitive styles (i.e., ‘brain types’). Those who are type E (bias towards empathizing) preferred music on the Mellow dimension (R&B/soul, adult contemporary, soft rock genres) compared to type S (bias towards systemizing) who preferred music on the Intense dimension (punk, heavy metal, and hard rock). Analyses of fine-grained psychological and sonic attributes in the music revealed that type E individuals preferred music that featured low arousal (gentle, warm, and sensual attributes), negative valence (depressing and sad), and emotional depth (poetic, relaxing, and thoughtful), while type S preferred music that featured high arousal (strong, tense, and thrilling), and aspects of positive valence (animated) and cerebral depth (complexity). The application of these findings for clinicians, interventions, and those on the autism spectrum (largely type S or extreme type S) are discussed. PMID:26200656

Those who are type E (bias towards empathizing) preferred music on the Mellow dimension (R&B/soul, adult contemporary, soft rock genres) compared to type S (bias towards systemizing) who preferred music on the Intense dimension (punk, heavy metal, and hard rock). Analyses of fine-grained psychological and sonic attributes in the music revealed that type E individuals preferred music that featured low arousal (gentle, warm, and sensual attributes), negative valence (depressing and sad), and emotional depth (poetic, relaxing, and thoughtful), while type S preferred music that featured high arousal (strong, tense, and thrilling), and aspects of positive valence (animated) and cerebral depth (complexity). The application of these findings for clinicians, interventions, and those on the autism spectrum (largely type S or extreme type S) are discussed.

  10. Musical Preferences are Linked to Cognitive Styles.

    David M Greenberg

    Full Text Available Why do we like the music we do? Research has shown that musical preferences and personality are linked, yet little is known about other influences on preferences such as cognitive styles. To address this gap, we investigated how individual differences in musical preferences are explained by the empathizing-systemizing (E-S theory. Study 1 examined the links between empathy and musical preferences across four samples. By reporting their preferential reactions to musical stimuli, samples 1 and 2 (Ns = 2,178 and 891 indicated their preferences for music from 26 different genres, and samples 3 and 4 (Ns = 747 and 320 indicated their preferences for music from only a single genre (rock or jazz. Results across samples showed that empathy levels are linked to preferences even within genres and account for significant proportions of variance in preferences over and above personality traits for various music-preference dimensions.

    At least to some extent migration behavior is the outcome of a preference for migration. The pattern of migration as an outcome of a preference for migration depends on two key factors: imitation technology and migration feasibility. We show that these factors jointly determine the outcome of a preference for migration and we provide examples that illustrate how the prevalence and transmission of a migration-forming preference yield distinct migration patterns. In particular, the imitation of...

    Full Text Available El objetivo de esta investigación es describir, desde la perspectiva etnográfica, cómo podría estar afectada la calidad de vida de los cuidadores familiares de adultos mayores con dependencia funcional, como consecuencia del desempeño del rol de cuidador, y según su percepción. Se trata de un estudio cualitativo etnográfico, con apoyo en la etnografía enfocada, en 14 cuidadoras familiares de adultos mayores de 65 años, con más de seis meses a su cuidado, en el municipio de Envigado, Colombia, en 2002, y una muestra de quince entrevistas en profundidad. El análisis de las entrevistas identificó siete grandes temas o categorías con las percepciones de las cuidadoras sobre su rol y los efectos de éste en su calidad de vida: significado de calidad de vida, percepción de la cuidadora sobre el rol de cuidadora, consecuencias del rol sobre su salud física y mental, relaciones cuidadora y persona cuidada, conocimientos y aprendizajes sobre el cuidado de las personas, apoyos que recibe la cuidadora para el cuidado, y la invisibilidad del trabajo de las cuidadoras. Las categorías que emergieron coinciden con las de otros estudios; se hace énfasis en la categoría "la invisibilidad del trabajo de la cuidadora familiar", en tanto es la menos documentada en la literatura, y en la importancia del acercamiento a los valores y las tradiciones de grupos para la interpretación de las respuestas de su vida social.

La seva finalitat és poder donar resposta a dos qüestions principals: identificar les característiques diferencials de l’EF respecte a l’EnF i comprovar si aquestes característiques diferencials han permès a les EF aguantar millor la crisi econòmica. Disseny/metodologia: S’ha analitzat una mostra de 750 grans i mitjanes empreses de Catalunya (550 familiars i 200 no familiars durant el període 2008-2012. Les dades s’han obtingut a través de la base de dades SABI, i per a la classificació de les empreses en familiars i no familiars s’ha dut a terme una comprovació individual de cadascuna d’elles per evitar habituals errors de classificació. Posteriorment les empreses s’han classificat en funció de la seva dimensió per dotar d’una major robustes els resultats. També s’ha procurat que la distribució d’empreses per sectors fos similar en les diferents categories per evitar que un efecte sectorial pogués tergiversar els resultats de l’estudi. Aportacions i resultats: L’estudi ha permès constatar les hipòtesis establertes sobre el finançament de les empreses familiars i concloure que aquestes presenten una estructura financera diferent a les Empreses no familiars. Les empreses familiars als seus balanços, presenten un major nivell d’autofinançament gràcies a la seva menor distribució de dividends. A més a més, les EF presenten millors resultats en quant a nivells de cobertura i liquiditat, ja que es troben més capitalitzades i presenten uns nivells d’endeutament inferior que les Empreses no familiars. Aquestes característiques patrimonials i financeres han contribuït a que les empreses familiars aguantin millor els anys de crisi, produint-se durant aquests anys

We examine these preferences in the context of laboratory experiments over small, anonymous groups, although...... the methodological issues extend to larger groups that form endogenously (e.g., families, committees, communities). Preferences over social risk can be closely approximated by individual risk attitudes when subjects have no information about the risk preferences of other group members.

  10. Familiarity mediates the relationship between emotional arousal and pleasure during music listening

    2013-09-01

    Full Text Available Emotional arousal appears to be a major contributing factor to the pleasure that listeners experience in response to music. Accordingly, a strong positive correlation between self-reported pleasure and electrodermal activity (EDA, an objective indicator of emotional arousal, has been demonstrated when individuals listen to familiar music. However, it is not yet known to what extent familiarity contributes to this relationship. In particular, as listening to familiar music involves expectations and predictions over time based on veridical knowledge of the piece, it could be that such memory factors plays a major role. Here, we tested such a contribution by using musical stimuli entirely unfamiliar to listeners. In a second experiment we repeated the novel music to experimentally establish a sense of familiarity. We aimed to determine whether (1 pleasure and emotional arousal would continue to correlate when listeners have no explicit knowledge of how the tones will unfold, and (2 whether this could be enhanced by experimentally-induced familiarity. In the first experiment, we presented 33 listeners with 70 unfamiliar musical excerpts in two sessions. There was no relationship between the degree of experienced pleasure and emotional arousal as measured by EDA. In the second experiment, 7 participants listened to 35 unfamiliar excerpts over two sessions separated by 30 minutes. Repeated exposure significantly increased EDA, even though individuals did not explicitly recall having heard all the pieces before. Furthermore, increases in self-reported familiarity significantly enhanced experienced pleasure and there was a general, though not significant, increase in EDA. These results suggest that some level of expectation and predictability mediated by prior exposure to a given piece of music play an important role in the experience of emotional arousal in response to music.

    Drewnowski, Adam; Mennella, Julie A.; Johnson, Susan L.; Bellisle, France

    2012-01-01

    Human desire for sweet taste spans all ages, races, and cultures. Throughout evolution, sweetness has had a role in human nutrition, helping to orient feeding behavior toward foods providing both energy and essential nutrients. Infants and young children in particular base many of their food choices on familiarity and sweet taste. The low cost and ready availability of energy-containing sweeteners in the food supply has led to concerns that the rising consumption of added sugars is the driving force behind the obesity epidemic. Low-calorie sweeteners are one option for maintaining sweet taste while reducing the energy content of children’s diets. However, their use has led to further concerns that dissociating sweetness from energy may disrupt the balance between taste response, appetite, and consumption patterns, especially during development. Further studies, preferably based on longitudinal cohorts, are needed to clarify the developmental trajectory of taste responses to low-calorie sweeteners and their potential impact on the diet quality of children and youth.

    Previous research has indicated that the medial temporal lobe (MTL), and more specifically the perirhinal cortex, plays a role in the feeling of familiarity for non-musical stimuli. Here, we examined contribution of the MTL to the feeling of familiarity for music by testing patients with unilateral MTL lesions. We used a gating paradigm: segments of familiar and unfamiliar musical excerpts were played with increasing durations (250, 500, 1000, 2000, 4000 ms and complete excerpts), and participants provided familiarity judgments for each segment. Based on the hypothesis that patients might need longer segments than healthy controls (HC) to identify excerpts as familiar, we examined the onset of the emergence of familiarity in HC, patients with a right MTL resection (RTR), and patients with a left MTL resection (LTR). In contrast to our hypothesis, we found that the feeling of familiarity was relatively spared in patients with a right or left MTL lesion, even for short excerpts. All participants were able to differentiate familiar from unfamiliar excerpts as early as 500 ms, although the difference between familiar and unfamiliar judgements was greater in HC than in patients. These findings suggest that a unilateral MTL lesion does not impair the emergence of the feeling of familiarity. We also assessed whether the dynamics of the musical excerpt (linked to the type and amount of information contained in the excerpts) modulated the onset of the feeling of familiarity in the three groups. The difference between familiar and unfamiliar judgements was greater for high than for low-dynamic excerpts for HC and RTR patients, but not for LTR patients. This indicates that the LTR group did not benefit in the same way from dynamics. Overall, our results imply that the recognition of previously well-learned musical excerpts does not depend on the integrity of either right or the left MTL structures. Patients with a unilateral MTL resection may compensate for the effects of

  16. A familiarity disadvantage for remembering specific images of faces.

    Armann, Regine G M; Jenkins, Rob; Burton, A Mike

    2016-04-01

    Familiar faces are remembered better than unfamiliar faces. Furthermore, it is much easier to match images of familiar than unfamiliar faces. These findings could be accounted for by quantitative differences in the ease with which faces are encoded. However, it has been argued that there are also some qualitative differences in familiar and unfamiliar face processing. Unfamiliar faces are held to rely on superficial, pictorial representations, whereas familiar faces invoke more abstract representations. Here we present 2 studies that show, for 1 task, an advantage for unfamiliar faces. In recognition memory, viewers are better able to reject a new picture, if it depicts an unfamiliar face. This rare advantage for unfamiliar faces supports the notion that familiarity brings about some representational changes, and further emphasizes the idea that theoretical accounts of face processing should incorporate familiarity.

    The Hawking-Penrose theorems tell us that solutions of Einstein's equations are generally singular, in the sense of the incompleteness of causal geodesics (the paths of physical observers). These singularities might be marked by the blowup of curvature and therefore crushing tidal forces, or by the breakdown of physical determinism. Penrose has conjectured (in his `Strong Cosmic Censorship Conjecture`) that it is generically unbounded curvature that causes singularities, rather than causal breakdown. The verification that ``AVTD behavior'' (marked by the domination of time derivatives over space derivatives) is generically present in a family of solutions has proven to be a useful tool for studying model versions of Strong Cosmic Censorship in that family. I discuss some of the history of Strong Cosmic Censorship, and then discuss what is known about AVTD behavior and Strong Cosmic Censorship in families of solutions defined by varying degrees of isometry, and discuss recent results which we believe will extend this knowledge and provide new support for Strong Cosmic Censorship. I also comment on some of the recent work on ``Weak Null Singularities'', and how this relates to Strong Cosmic Censorship.

    This study examines the use of intrinsic and extrinsic cues in beef quality perception at the point of purchase and upon consumption by consumers with varying levels of familiarity with a particular beef product. High-familiarity consumers tend to use the color of the meat to assess beef quality......, whereas low-familiarity consumers tend to believe that the brand is the most valid cue for assessing beef quality. However, due to the lack of consistency in sensory beef quality, high-familiarity consumers’ ability to form quality expectations that are predictive of their quality experience is no better...

    There remains controversy about the contribution of food advertising targeted at children to the epidemic of childhood obesity in the UK. The aim of this study is to explore the relationship between the ability to recognize brand logos featured in promotional campaigns of the food industry and eating behaviours, food knowledge and preferences in children aged 9-11 attending six primary schools in Birmingham, West Midlands. A '20 flashcard' brand logo quiz assessed children's brand logo recognition ability; a self-completed questionnaire collected information on children's socio-demographic characteristics, eating behaviours, food knowledge and preferences (n=476). Children demonstrated both high brand logo recognition abilities with 88.4% (420/476) recognizing at least 16/20 brand logos in the quiz and high levels of poor diet. No strong correlation was found between higher brand logo recognition ability and poorer eating behaviours, food knowledge and preferences. Although many children are familiar with commonly presented logos of food products, brand awareness does not appear to be a major influence on the consumption of a poor diet amongst children. The regulation or restriction of food advertising to children is unlikely to have a significant impact on obesity rates among children unless combined with measures to address other detrimental influences.

    As a social species zebra finches might be expected to copy the food choices of more experienced conspecifics. This prediction has been tested previously by presenting observers with two demonstrator birds that differ in some way (e.g., sex, familiarity), each feeding on a different colour food source. However, if the observer subsequently exhibits a preference, it is unclear whether it has copied the choice of one demonstrator or avoided the choice of the other. Furthermore, this choice may actually be influenced by pre-existing preferences, a potential bias that is rarely tested. Here we examine whether apparent copying or avoidance can be explained by pre-existing preferences. In Experiment 1, observers had the opportunity to watch a conspecific forage from one of the two differently coloured food hoppers. In Experiment 2, the observers did not have this opportunity. In both experiments observers were subsequently tested for their food hopper preference and all but one preferred one colour over the other. In Experiment 1 some observers showed evidence for copying, while others seemed to avoid the colour preferred by the demonstrator. In Experiment 2 females generally preferred the white hopper. Pre-existing colour preferences could, therefore, explain the apparent copying/avoidance we observed. This article is part of a Special Issue entitled: Cognition in the wild.

    Full Text Available La violencia filio-parental es un problema social cualitativamente diferente a otros tipos de violencia familiar, porque los adolescentes dirigen la violencia hacia quienes debieran representar la autoridad y proporcionarles bienestar. El objetivo principal de este estudio era analizar el papel de las relaciones paternofiliales y la disciplina familiar en el desarrollo de conductas violentas y prosociales de los adolescentes hacia sus padres. En el estudio participaron 585 hijos/as (48% varones entre 12 y 18 años procedentes de 8 centros escolares de la Comunidad Autónoma del País Vasco. Los resultados indican que las relaciones familiares basadas en el afecto y la comunicación son las que favorecen las conductas prosociales de los hijos, y reducen las conductas violentas de éstos en el hogar. Por el contrario, las estrategias de disciplina parental coercitivas y las estrategias parcialmente coercitivas (supervisión y coste de respuesta se asocian a un mayor nivel de violencia física y psicológica de los hijos adolescentes hacia sus padres. Finalmente, se discuten las implicaciones de estos resultados en relación a la educación parental.

    Selective breeding alcohol-preferring (P) and alcohol-nonpreferring (NP) rats showed a strong preference for the sucrose solutions, whereas P rats intake greater amounts than NP rats. The aim of this study was the estimation of selectively bred ethanol-preferring (WHP - Warsaw High Preferring) and ethanol-nonpreferring (WLP - Warsaw Low Preferring) rats for their preference for various tastes. The oral drinking of the following substances was studied at a range of concentrations: sucrose (0.5-64.0 g/100 ml), NaCl (0.025-3.2 g/100 ml), citric acid (0.008-2.048 g/l), and sucrose octaacetate (0.002-0.512 g/l) solutions. Separate groups of 7-8 rats from each line were investigated of each of the four tastes. The investigated solutions were presented continuously keeping water and food always available. Concentrations of the various flavors were doubled every 48 h. Rats from WHP and WLP lines clearly revealed the preference for the sucrose solution and the highest preference was at the 4.0 and 8.0 g/100ml sucrose concentration. Similar to sucrose, both lines exposed strong preference for the NaCl solution and this preference enhanced together with the increase of the NaCl concentration. Nevertheless their preference for the NaCl solutions decreased when the concentration of NaCl reached 1.600 g/100 ml. Both lines of rats did not differ in citric acid or sucrose octaacetate intake at any of the concentrations studied. Selective breeding of rats (WHP) for high and rats (WLP) for low ethanol drinking is favorably correlated with the drinking of sweet and salty solutions and negatively correlated with the consumption of sour and bitter tastes.

  17. The Influence of Familiarity on Affective Responses to Natural Scenes

    Science.gov (United States)

    Sanabria Z., Jorge C.; Cho, Youngil; Yamanaka, Toshimasa

    This kansei study explored how familiarity with image-word combinations influences affective states. Stimuli were obtained from Japanese print advertisements (ads), and consisted of images (e.g., natural-scene backgrounds) and their corresponding headlines (advertising copy). Initially, a group of subjects evaluated their level of familiarity with images and headlines independently, and stimuli were filtered based on the results. In the main experiment, a different group of subjects rated their pleasure and arousal to, and familiarity with, image-headline combinations. The Self-Assessment Manikin (SAM) scale was used to evaluate pleasure and arousal, and a bipolar scale was used to evaluate familiarity. The results showed a high correlation between familiarity and pleasure, but low correlation between familiarity and arousal. The characteristics of the stimuli, and their effect on the variables of pleasure, arousal and familiarity, were explored through ANOVA. It is suggested that, in the case of natural-scene ads, familiarity with image-headline combinations may increase the pleasure response to the ads, and that certain components in the images (e.g., water) may increase arousal levels.

    Rhythmic auditory stimulation (RAS) is a gait rehabilitation method in which patients synchronize footsteps to a metronome or musical beats. Although RAS with music can ameliorate gait abnormalities, outcomes vary, possibly because music properties, such as groove or familiarity, differ across interventions. To optimize future interventions, we assessed how initially familiar and unfamiliar low-groove and high-groove music affected synchronization accuracy and gait in healthy individuals. We also experimentally increased music familiarity using repeated exposure to initially unfamiliar songs. Overall, familiar music elicited faster stride velocity and less variable strides, as well as better synchronization performance (matching of step tempo to beat tempo). High-groove music, as reported previously, led to faster stride velocity than low-groove music. We propose two mechanisms for familiarity's effects. First, familiarity with the beat structure reduces cognitive demands of synchronizing, leading to better synchronization performance and faster, less variable gait. Second, familiarity might have elicited faster gait by increasing enjoyment of the music, as enjoyment was higher after repeated exposure to initially low-enjoyment songs. Future studies are necessary to dissociate the contribution of these mechanisms to the observed RAS effects of familiar music on gait. © 2015 New York Academy of Sciences.

    Full Text Available Se debate el punto de vista que identifica la familia extensa con la tradición y la familia nuclear con el moderno modelo industrial de vida familiar. También se analiza la actual opinión dominante que afirma que la familia ha perdido el papel preponderante social y económico en la sociedad occidental. Se estudian los modelos cambiantes de familia en el Reino Unido, Francia y, especialmente, España. Los aspectos más tratados son los siguientes : la aceptación de los nuevos tipos de relaciones entre los jóvenes, opinión sobre la cohabitación, la imagen del matrimonio como institución, la postura ante el divorcio, el grado de rigidez ante la infidelidad matrimonial, la actitud ante la sexualidad y el grado de deseo de diferenciación de roles entre los sexos. Los datos utilizados están extraídos del banco de datos del Centro de Investigaciones Socilógicas. Como conclusión, se puede decir que en España se siguen las mismas tendencias que en otros países desarrollados : un descenso del valor del matrimonio como institución y un incremento de las relaciones informales.

    To test Music Marker Theory (MMT) positing that early adolescents' preferences for nonmainstream types of popular music indicate concurrent and later minor delinquency. MMT was tested in a 4-year longitudinal study (n = 309). The results showed that early fans of different types of rock (eg, rock, heavy metal, gothic, punk), African American music (rhythm and blues, hip-hop), and electronic dance music (trance, techno/hardhouse) showed elevated minor delinquency concurrently and longitudinally. Preferring conventional pop (chart pop) or highbrow music (classic music, jazz), in contrast, was not related to or was negatively related to minor delinquency. Early music preferences emerged as more powerful indicators of later delinquency rather than early delinquency, indicating that music choice is a strong marker of later problem behavior. The mechanisms through which music preferences are linked to minor delinquency are discussed within the framework of MMT.

    ABSTRACT An expanding literature indicates that in multiparty systems with coalition governments, citizens consider the post-electoral bargaining process among parties when casting their vote. Yet, we know surprisingly little about the nature of voters’ coalition preferences. This paper uses data from the Austrian National Election Study to examine the determinants as well as the independence of preferences for coalitions as political object. We find that coalition preferences are strongly informed by spatial considerations; but additional non-ideological factors, such as party and leader preferences, also play a fundamental role. We also find that coalitions enjoy a certain degree of independence from other objects of vote choice and they do not always represent a simple average score on the feeling thermometer of the constituent parties. There are, however, substantial differences among voters, with party identifiers and those with extreme ideology being less likely to consider coalitions as separate entities from their component parties.

  5. Visual perspective during remembering: ERP evidence of familiarity-based source monitoring.

    2017-06-01

    Autobiographical recollections are accompanied by visual perspectives that can be either a view through the person's own eyes (first-person) or a view that integrates visual characteristics of the rememberer into the reconstructed scene (third-person). Some have argued that a third-person perspective serves as a coping mechanism allowing the person to distance themselves from details of painful memories. The study reported here created first- and third-person memories in a novel experimental paradigm. Later, participants discriminated between these perspectives on a source memory test while event-related potentials (ERPs) were recorded. Experimental evidence from the current study suggests that memories from different perspectives can be effectively modeled in the lab. Directly comparing first-person and third-person memories revealed no strong source memory or ERP differences; however, more first-person memories were recognized. Surprisingly, the modeling of the behavioral data using ROC curves and Dual Process Signal Detection (DPSD) measures of recollection and familiarity suggest that familiarity contributed to source judgments of both first- and third-person memories. The ERP data support this claim because the putative ERP correlate of familiarity (i.e., FN400) was observed during the source test. Because source monitoring tends to draw on recollection, evidence of familiarity-based source monitoring has been elusive, and these results support a key prediction of the Source Monitoring Framework (SMF) - that source decisions can be based on familiarity in some contexts (Johnson, Hashtroudi, & Lindsay, 1993; Mitchell & Johnson, 2009).

Results demonstrate that the memory color effect occurs only in the high-familiarity condition, but not in the middle- and low-familiarity conditions. Furthermore, there is a positive correlation between the memory color effect and the actual number of domestic stores of the brand. In Experiment 2, we assessed the semantic association between logos and food/beverage names by using a semantic priming task to elucidate whether the memory color effect of logos relates to consumer brand cognition, and found that the semantic associations between logos and food/beverage names in the high-familiarity brands were stronger than those in the low-familiarity brands only when the logos were colored correctly, but not when they were appropriately or inappropriately colored, or achromatic.The current results provide behavioral evidence of the relationship between the familiarity of objects and the memory color effect and suggest that the memory color effect increases with the familiarity of objects, albeit not constantly.

    Full Text Available

    <strong>ABSTRACT strong>

    BACKGROUND>: Data on age in developing countries are subject to errors, particularly in circumstances where literacy levels are not high. A common error in age reporting is the tendency of rounding the ages to the nearest figure ending in ‘0’ or ‘5’ or to a lesser extent, to the nearest even  number. Because of this tendency, commonly known as “digital preference”, age heaping occurs at certain ages. The aim of this study was to study this phenomenon and both Myers’ and Whipple’s Indexes were employed to identify the digit preference in Iranian national census, 2005.
    <strong>METHODS>: Myers’ and Whipple’s Indexes were employed to study the pattern of digit preference. The Myers' Blended Index shows heaping at ages ending in 0 and 5 years, and the pattern of heaping is pronounced for both urban and rural populations.
    <strong>RESULTS>: The quality of age reporting for the 2005 census data was poor if compared to the 1995 census data. Digit preference occurred most often in the female population compared to male one, and in rural areas compared to urban ones.
    <strong>CONCLUSIONS>: It can be concluded that both males and females tend to misreport their ages before age 60 especially in rural areas. So, whenever any data gathering regarding age information occurs, the ID card should be used regardless of person's self report.

  10. Strong Electroweak Symmetry Breaking

    Grinstein, Benjamin

    2011-01-01

    Models of spontaneous breaking of electroweak symmetry by a strong interaction do not have fine tuning/hierarchy problem. They are conceptually elegant and use the only mechanism of spontaneous breaking of a gauge symmetry that is known to occur in nature. The simplest model, minimal technicolor with extended technicolor interactions, is appealing because one can calculate by scaling up from QCD. But it is ruled out on many counts: inappropriately low quark and lepton masses (or excessive FCNC), bad electroweak data fits, light scalar and vector states, etc. However, nature may not choose the minimal model and then we are stuck: except possibly through lattice simulations, we are unable to compute and test the models. In the LHC era it therefore makes sense to abandon specific models (of strong EW breaking) and concentrate on generic features that may indicate discovery. The Technicolor Straw Man is not a model but a parametrized search strategy inspired by a remarkable generic feature of walking technicolor,...

    Baldo, M.; Ducoin, C.

    2011-01-01

    We present a study of the possible plasmon excitations that can occur in systems where strong superconductivity is present. In these systems the plasmon energy is comparable to or smaller than the pairing gap. As a prototype of these systems we consider the proton component of Neutron Star matter just below the crust when electron screening is not taken into account. For the realistic case we consider in detail the different aspects of the elementary excitations when the proton, electron components are considered within the Random-Phase Approximation generalized to the superfluid case, while the influence of the neutron component is considered only at qualitative level. Electron screening plays a major role in modifying the proton spectrum and spectral function. At the same time the electron plasmon is strongly modified and damped by the indirect coupling with the superfluid proton component, even at moderately low values of the gap. The excitation spectrum shows the interplay of the different components and their relevance for each excitation modes. The results are relevant for neutrino physics and thermodynamical processes in neutron stars. If electron screening is neglected, the spectral properties of the proton component show some resemblance with the physical situation in high-T c superconductors, and we briefly discuss similarities and differences in this connection. In a general prospect, the results of the study emphasize the role of Coulomb interaction in strong superconductors.

    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

Data sets consist of finitely many observations of price vectors and consumption bundles. A preference relation rationalizes a data set provided that for every observed...... many observations of price vectors, lists of individual incomes and aggregate demands.

    Full Text Available Evaluating the familiarity of faces is critical for social animals as it is the basis of individual recognition. In the present study, we examined how face familiarity is reflected in neural activities in our closest living relative, the chimpanzee. Skin-surface event-related brain potentials (ERPs were measured while a fully awake chimpanzee observed photographs of familiar and unfamiliar chimpanzee faces (Experiment 1 and human faces (Experiment 2. The ERPs evoked by chimpanzee faces differentiated unfamiliar individuals from familiar ones around midline areas centered on vertex sites at approximately 200 ms after the stimulus onset. In addition, the ERP response to the image of the subject’s own face did not significantly diverge from those evoked by familiar chimpanzees, suggesting that the subject’s brain at a minimum remembered the image of her own face. The ERPs evoked by human faces were not influenced by the familiarity of target individuals. These results indicate that chimpanzee neural representations are more sensitive to the familiarity of conspecific than allospecific faces.

    Neck pain (NP) and low back pain (LBP) are highly prevalent. Exercise therapy helps, but effect sizes and therapy compliance remain low. Client-centred therapy and technology use may play a role to improve therapy outcomes. To offer technology supported rehabilitation matching patient's goals, training preferences for rehabilitation and technology familiarity need to be known. This study aims to (1) inventory training preferences and motives, (2) evaluate whether these change during rehabilitation, and (3) evaluate familiarity with using technologies, in persons with NP/LBP. Semi-structured interviews were conducted with regard to training preferences and usage of mainstream technological devices. Persons with NP (n = 40) preferred to train on "lifting", "prolonged sitting" and "driving a car". Persons with LBP (n = 40) preferred to train on "household activities", "lifting" and "prolonged walking". Motives were predominantly "ability to work" and "ability to do free time occupations". Preferences shifted in ranking but remained the same during rehabilitation. Participants were familiar with the surveyed technologies. Persons with NP or LBP prefer to train on exercises supporting the improvement of everyday life skills. They use technologies in their professional and personal life, which may lower the threshold for the adoption of rehabilitation technologies. Implications for rehabilitation Persons with neck pain (NP) and persons with low back pain (LBP) prefer to train on specific activities that limit their functional ability during daily tasks. The underlying motives linked to preferred training activities are predominantly "being able to work" and "being able to perform free time occupations". Persons with NP and persons with LBP are accustomed to the use of mainstream technologies and the integration of these technologies in rehabilitation settings seems feasible. In order to enable technology supported rehabilitation that is client

    1984-03-01

    Standard path-integral techniques such as instanton calculations give good answers for weak-coupling problems, but become unreliable for strong-coupling. Here we consider a method of replacing the original potential by a suitably chosen harmonic oscillator potential. Physically this is motivated by the fact that potential barriers below the level of the ground-state energy of a quantum-mechanical system have little effect. Numerically, results are good, both for quantum-mechanical problems and for massive phi 4 field theory in 1 + 1 dimensions. 9 references, 6 figures

    With an assumed weak multiplet structure for bosonic hadrons, which is consistent with the ΔI = 1/2 rule, it is shown that the strong interaction effective hamiltonian is compatible with the weak SU(2) x U(1) gauge transformation. Especially the rho-meson transforms as a triplet under SU(2)sub(w), and this is the origin of the rho-photon analogy. It is also shown that the existence of the non-vanishing Cabibbo angle is a necessary condition for the absence of the exotic hadrons. (orig.)

  3. The role of long-term and short-term familiarity in visual and haptic face recognition.

    Casey, Sarah J; Newell, Fiona N

    2005-10-01

    Recent studies have suggested that the familiarity of a face leads to more robust recognition, at least within the visual domain. The aim of our study was to investigate whether face familiarity resulted in a representation of faces that was easily shared across the sensory modalities. In Experiment 1, we tested whether haptic recognition of a highly familiar face (one's own face) was as efficient as visual recognition. Our observers were unable to recognise their own face models from tactile memory alone but were able to recognise their faces visually. However, haptic recognition improved when participants were primed by their own live face. In Experiment 2, we found that short-term familiarisation with a set of previously unfamiliar face stimuli improved crossmodal recognition relative to the recognition of unfamiliar faces. Our findings suggest that familiarisation provides a strong representation of faces but that the nature of the information encoded during learning is critical for efficient crossmodal recognition.

    This study examines the effects of branding and packaging on young children's taste preferences. Preschool children aged 3 to 5 (n=65) tasted five pairs of identical foods in packaging from McDonald's and in matched packaging that was either plain, Starbucks-branded, or colourful (but unbranded). Children were asked if the foods tasted the same or if one tasted better. Children preferred the taste of foods wrapped in decorative wrappings, relying more on aesthetics than on familiar branding when making their choices. The findings suggest the need to explore questions beyond commercial advertising (and brand promotion) on television and other media platforms. More attention should be directed at the important role of packaging in directing children's food preferences.

  7. Strong Coupling Holography

    Dvali, Gia

    2009-01-01

    We show that whenever a 4-dimensional theory with N particle species emerges as a consistent low energy description of a 3-brane embedded in an asymptotically-flat (4+d)-dimensional space, the holographic scale of high-dimensional gravity sets the strong coupling scale of the 4D theory. This connection persists in the limit in which gravity can be consistently decoupled. We demonstrate this effect for orbifold planes, as well as for the solitonic branes and string theoretic D-branes. In all cases the emergence of a 4D strong coupling scale from bulk holography is a persistent phenomenon. The effect turns out to be insensitive even to such extreme deformations of the brane action that seemingly shield 4D theory from the bulk gravity effects. A well understood example of such deformation is given by large 4D Einstein term in the 3-brane action, which is known to suppress the strength of 5D gravity at short distances and change the 5D Newton's law into the four-dimensional one. Nevertheless, we observe that the ...

    Lateralization of cognitive processes and motor functions has been demonstrated in a number of species, including humans, elephants, and cetaceans. For example, bottlenose dolphins (Tursiops truncatus) have exhibited preferential eye use during a variety of cognitive tasks. The present study investigated the possibility of visual lateralization in 12 belugas (Delphinapterus leucas) and six Pacific white-sided dolphins (Lagenorhynchus obliquidens) located at two separate marine mammal facilities. During free swim periods, the belugas and Pacific white-sided dolphins were presented a familiar human, an unfamiliar human, or no human during 10-15 min sessions. Session videos were coded for gaze duration, eye presentation at approach, and eye preference while viewing each stimulus. Although we did not find any clear group level lateralization, we found individual left eye lateralized preferences related to social stimuli for most belugas and some Pacific white-sided dolphins. Differences in gaze durations were also observed. The majority of individual belugas had longer gaze durations for unfamiliar rather than familiar stimuli. These results suggest that lateralization occurs during visual processing of human stimuli in belugas and Pacific white-sided dolphins and that these species can distinguish between familiar and unfamiliar humans.

    Brain responses to feed flavors with or without a feed additive (FA) were investigated in piglets familiarized or not with this FA. Sixteen piglets were allocated to 2 dietary treatments from weaning until d 37: the naive group (NAI) received a standard control feed and the familiarized group (FAM) received the same feed added with a FA mainly made of orange extracts. Animals were subjected to a feed transition at d 16 post-weaning, and to 2-choice feeding tests at d 16 and d 23. Production traits of the piglets were assessed up to d 28 post-weaning. From d 26 onwards, animals underwent 2 brain imaging sessions (positron emission tomography of 18FDG) under anesthesia to investigate the brain activity triggered by the exposure to the flavors of the feed with (FA) or without (C) the FA. Images were analyzed with SPM8 and a region of interest (ROI)-based small volume correction (p reward, and included the prefrontal cortex, insular cortex, fusiform gyrus, limbic system and corpus striatum. The FAM animals showed a moderate preference for the novel post-transition FA feed compared to the C feed on d 16, i.e., day of the feed transition (67% of total feed intake). The presence or absence of the FA in the diet from weaning had no impact on body weight, average daily gain, and feed efficiency of the animals over the whole experimental period (p ≥ 0.10). Familiar feed flavors activated the prefrontal cortex. The amygdala, insular cortex, and prepyriform area were only activated in familiarized animals exposed to the FA feed flavor. The perception of FA feed flavor in the familiarized animals activated the dorsal striatum differently than the perception of the C feed flavor in naive animals. Our data demonstrated that the perception of FA in familiarized individuals induced different brain responses in regions involved in reward anticipation and/or perception processes than the familiar control feed flavor in naive animals. Chronic exposure to the FA might be necessary

    Familiarity participates in the pathogenesis of hypertension, although only recently, whole genome studies have proposed regions of the human genome possibly involved in the transmission of the hypertensive phenotype. Although studies have mainly focused on autosome, hitherto the influence of sex on familial transmission of hypertension has not been considered. We analysed the database of the Campania Salute Network of Hypertension center of the Federico II University Hospital of Naples (Italy), using dichotomous variables for paternal and maternal familiarity and gender (male and female) of 12 504 hypertensive patients (6868 males and 5636 females) and 6352 controls (3484 males and 2868 females), totaling 18 856 subjects. In the hypertensive group, familiarity was present in 75% of cases with odds of 3.77 and in only 26% of the normotensives with odds of 0.94. The odds ratio (OR) indicated that familiarity increases the risk of developing hypertension by 2.91 (95% confidence interval (CI)=2.67–3.17, P<0.001) times. Additionally, maternal familiarity was 37% (OR=3.01, 95% CI=2.66–3.41, P<0.001), paternal familiarity was 21% (OR=2.31, 95% CI=2.01–2.68, P<0.001) and the double familiarity was 17% (OR=3.45, 95% CI=2.87–4.01, P<0.001), thus suggesting a plausible association between maternal familiarity and development of hypertension; this finding was observed both in male and in female patients, although the phenomenon was larger in males. Given the dominance of maternal transmission in males, by genome-wide analysis of the X chromosome, we found two regions that were differently distributed in male hypertensives with maternal hypertension. Our data highlight the importance of genetic variants in the X chromosome to the maternal transmission of the hypertensive phenotype. PMID:26911533

El objetivo de esta investigación fue valorar la relación entre el funcionamiento familiar percibido por estudiantes españoles de educación secundaria postobligatoria y su práctica de ocio digital. La muestra ascendió a 1.764 estudiantes. El ocio digital se midió a partir de una pregunta abierta en la que debían señalar las tres actividades de ocio más importantes, y el funcionamiento familiar se valoró mediante la versión española del FACES IV (Escala de cohesión y adaptación familiar. Se realizó un análisis descriptivo sobre las actividades de ocio digital de los jóvenes, se determinó el coeficiente del funcionamiento familiar de cada sujeto y mediante análisis de varianza (ANOVA de un factor se valoró la relación entre el funcionamiento familiar percibido por los estudiantes y las actividades de ocio digital practicadas por los mismos. Los jóvenes otorgan importancia a las actividades digitales de ocio, destacando la participación en redes sociales, jugar a videojuegos y navegar por Internet. La cohesión, la flexibilidad y el funcionamiento familiar gozan de mejor salud cuando los hijos no apuntan actividades digitales entre sus prácticas preferentes de ocio. Los resultados sugieren nuevas investigaciones que comprueben si esta asociación negativa entre funcionamiento familiar y ocio digital es causal o se debe a otros factores.

    In the process of map making, the attention is given to the resulting image map (to be accurate, readable, and suit the primary purpose) and its user aspects. Current cartography understands the user issues as all matters relating to user perception, map use and also user preferences. Most commercial cartographic production is strongly connected to economic circumstances. Companies are discovering user's interests and market demands. However, is it sufficient to focus just on the user's preferences? Recent research on user aspects at Palacký University Olomouc addresses a much wider scope of user aspects. The user's preferences are very often distorting - the users think that the particular image map is kind, beautiful, and useful and they wants to buy it (or use it - it depends on the form of the map production). But when the same user gets the task to use practically this particular map (such as finding the shortest way), so the user concludes that initially preferred map is useless, and uses a map, that was worse evaluated according to his preferences. It is, therefore, necessary to evaluate not only the correctness of image maps and their aesthetics but also to assess the user perception and other user issues. For the accomplishment of such testing, eye-tracking technology is a useful tool. The research analysed how users read image maps, or if they prefer image maps over traditional maps. The eye tracking experiment on the comparison of the conventional and image map reading was conducted. The map readers were asked to solve few simple tasks with either conventional or image map. The readers' choice of the map to solve the task was one of investigated aspect of user preferences. Results demonstrate that the user preferences and user needs are often quite different issues. The research outcomes show that it is crucial to implement map user testing into the cartographic production process.

    Wickens, F

    Our friend and colleague John Strong was cruelly taken from us by a brain tumour on Monday 31st July, a few days before his 65th birthday John started his career working with a group from Westfield College, under the leadership of Ted Bellamy. He obtained his PhD and spent the early part of his career on experiments at Rutherford Appleton Laboratory (RAL), but after the early 1970s his research was focussed on experiments in CERN. Over the years he made a number of notable contributions to experiments in CERN: The Omega spectrometer adopted a system John had originally developed for experiments at RAL using vidicon cameras to record the sparks in the spark chambers; He contributed to the success of NA1 and NA7, where he became heavily involved in the electronic trigger systems; He was responsible for the second level trigger system for the ALEPH detector and spent five years leading a team that designed and built the system, which ran for twelve years with only minor interventions. Following ALEPH he tur...

  7. Stirring Strongly Coupled Plasma

    2009-01-01

    We determine the energy it takes to move a test quark along a circle of radius L with angular frequency w through the strongly coupled plasma of N=4 supersymmetric Yang-Mills (SYM) theory. We find that for most values of L and w the energy deposited by stirring the plasma in this way is governed either by the drag force acting on a test quark moving through the plasma in a straight line with speed v=Lw or by the energy radiated by a quark in circular motion in the absence of any plasma, whichever is larger. There is a continuous crossover from the drag-dominated regime to the radiation-dominated regime. In the crossover regime we find evidence for significant destructive interference between energy loss due to drag and that due to radiation as if in vacuum. The rotating quark thus serves as a model system in which the relative strength of, and interplay between, two different mechanisms of parton energy loss is accessible via a controlled classical gravity calculation. We close by speculating on the implicati...

  8. Strong-interaction nonuniversality

    1989-01-01

    The universal QCD color theory is extended to an SU(3) 1 direct product SU(3) 2 direct product SU(3) 3 gauge theory, where quarks of the ith generation transform as triplets under SU(3)/sub i/ and singlets under the other two factors. The usual color group is then identified with the diagonal subgroup, which remains exact after symmetry breaking. The gauge bosons associated with the 16 broken generators then form two massive octets under ordinary color. The interactions between quarks and these heavy gluonlike particles are explicitly nonuniversal and thus an exploration of their physical implications allows us to shed light on the fundamental issue of strong-interaction universality. Nonuniversality and weak flavor mixing are shown to generate heavy-gluon-induced flavor-changing neutral currents. The phenomenology of these processes is studied, as they provide the major experimental constraint on the extended theory. Three symmetry-breaking scenarios are presented. The first has color breaking occurring at the weak scale, while the second and third divorce the two scales. The third model has the interesting feature of radiatively induced off-diagonal Kobayashi-Maskawa matrix elements

  11. Constructive Preference Elicitation

    Full Text Available When faced with large or complex decision problems, human decision makers (DM can make costly mistakes, due to inherent limitations of their memory, attention, and knowledge. Preference elicitation tools assist the decision maker in overcoming these limitations. They do so by interactively learning the DM’s preferences through appropriately chosen queries and suggesting high-quality outcomes based on the preference estimates. Most state-of-the-art techniques, however, fail in constructive settings, where the goal is to synthesize a custom or entirely novel configuration rather than choosing the best option among a given set of candidates. Many wide-spread problems are constructive in nature: customizing composite goods such as cars and computers, bundling products, recommending touristic travel plans, designing apartments, buildings, or urban layouts, etc. In these settings, the full set of outcomes is humongous and can not be explicitly enumerated, and the solution must be synthesized via constrained optimization. In this article, we describe recent approaches especially designed for constructive problems, outlining the underlying ideas and their differences as well as their limitations. In presenting them, we especially focus on novel issues that the constructive setting brings forth, such as how to deal with sparsity of the DM’s preferences, how to properly frame the interaction, and how to achieve efficient synthesis of custom instances.

    There is persisting interest in the idea that taste preferences are heritable characteristics, but few twin studies have found evidence for a significant genetic component. Small sample sizes and idiosyncratic selection of foods may have contributed to the negative results. We hypothesized that using a larger twin sample and empirical groupings of food types, would give stronger evidence for the heritability of food preferences. We examined the heritability of preferences for four food groups in a sample of young twins. We administered a food preference questionnaire with 95 foods to 214 mothers of same-sex twin pairs (103 monozygotic and 111 dizygotic pairs) aged 4 to 5. 18 foods were excluded because they had been tried by fewer than 25% of the children. Foods were grouped into 'Vegetables', 'Fruits', 'Desserts' and 'Meat and Fish' on the basis of a factor analysis of the preference data. Genetic analyses were carried out on mean liking across these four groups, using model fitting techniques. Over all 77 foods, MZ correlations were higher than DZ correlations for 72 of them, with a higher mean MZ correlation (r = 0.76) than DZ correlation (r = 0.56). Using model fitting techniques with the factor scores, significant heritability estimates were obtained for all four food groups. Heritability was modest for dessert foods (0.20), moderate for vegetables (0.37) and fruits (0.51), and high for liking for protein foods (0.78). Shared environmental effects were strong for desserts, fruits and vegetables, while non-shared environmental influences were low for all four food groups. These results provide strong evidence for modest heritability of food preferences when using empirically-derived groupings of foods.

  15. Colour preferences in nest-building zebra finches.

    Some bird species are selective in the materials they choose for nest building, preferring, for example, materials of one colour to others. However, in many cases the cause of these preferences is not clear. One of those species is the zebra finch, which exhibits strong preferences for particular colours of nest material. In an attempt to determine why these birds strongly prefer one colour of material over another, we compared the preferences of paired male zebra finches for nest material colour with their preferences for food of the same colours. We found that birds did indeed prefer particular colours of nest material (in most cases blue) but that they did not generally prefer food of one colour over the other colours. It appears, then, that a preference for one colour or another of nest material is specific to the nest-building context. This article is part of a Special Issue entitled: insert SI title.

    2015-04-01

    This exploratory study employed a netnographic approach (netnography being a research methodology that adopts the practices of ethnography in an Internet-based setting) to reveal opportunities for kindergarten food familiarization. The study analyses kindergarten teachers' discussions on seven Internet message boards regarding the various food and nutrition experiences in their classes. Semi-structured interviews were then conducted with seven kindergarten teachers to explore further the message board findings. Five opportunities for how food familiarization occurs in kindergartens emerged from the analysis. These opportunities were categorized as being either "overt": (1) nutrition lessons, (2) snack times, (3) cooking experiences, or "covert" (4) food as teaching materials, and (5) dramatic play centres. Overt refers to any opportunity centred on food, healthy eating, or nutrition, whereas covert refers to opportunities where food was involved but in a non-exclusive manner. The five opportunities are examined and discussed in terms of their implications for children's food preference development. Results should be useful for future researchers for two main reasons. First, the results demonstrate the wide variety of food and nutrition experiences kindergarten students encounter throughout the day, beyond healthy eating interventions or foods served during meals. And second, because the findings are preliminary they require further research using various methods of data collection and samples of teachers. Copyright © 2014 Elsevier Ltd. All rights reserved.

  18. The Neuropsychology of Familiar Person Recognition from Face and Voice

    Full Text Available Prosopagnosia has been considered for a long period of time as the most important and almost exclusive disorder in the recognition of familiar people. In recent years, however, this conviction has been undermined by the description of patients showing a concomitant defect in the recognition of familiar faces and voices as a consequence of lesions encroaching upon the right anterior temporal lobe (ATL. These new data have obliged researchers to reconsider on one hand the construct of ‘associative prosopagnosia’ and on the other hand current models of people recognition. A systematic review of the patterns of familiar people recognition disorders observed in patients with right and left ATL lesions has shown that in patients with right ATL lesions face familiarity feelings and the retrieval of person-specific semantic information from faces are selectively affected, whereas in patients with left ATL lesions the defect selectively concerns famous people naming. Furthermore, some patients with right ATL lesions and intact face familiarity feelings show a defect in the retrieval of person-specific semantic knowledge greater from face than from name. These data are at variance with current models assuming: (a that familiarity feelings are generated at the level of person identity nodes (PINs where information processed by various sensory modalities converge, and (b that PINs provide a modality-free gateway to a single semantic system, where information about people is stored in an amodal format. They suggest, on the contrary: (a that familiarity feelings are generated at the level of modality-specific recognition units; (b that face and voice recognition units are represented more in the right than in the left ATLs; (c that in the right ATL are mainly stored person-specific information based on a convergence of perceptual information, whereas in the left ATLs are represented verbally-mediated person-specific information.

    Biased or too strong preference for a particular object is often problematic, resulting in addiction and phobia. In animal models, alternative forced-choice tasks have been routinely used, but such preference test is far from daily situations that addicts or phobic are facing. In the present study, we developed a behavioral assay to evaluate the preference of sounds in rodents. In the assay, several sounds were presented according to the position of free-moving rats, and quantified the sound preference based on the behavior. A particular tone was paired with microstimulation to the ventral tegmental area (VTA), which plays central roles in reward processing, to increase sound preference. The behaviors of rats were logged during the classical conditioning for six days. Consequently, some behavioral indices suggest that rats search for the conditioned sound. Thus, our data demonstrated that quantitative evaluation of preference in the behavioral assay is feasible.

    The striped cucumber beetle (Acalymma vittatum (F.)) is a destructive pest of cucurbit crops, and management could be improved by host plant resistance, especially in organic farming systems. However, despite the variation in striped cucumber beetle preference observed within the economically important species, Cucurbita pepo L., plant breeders and entomologists lacked a simple framework to classify and exploit these differences. This study used recent phylogenetic evidence and bioassays to organize striped cucumber beetle preference within C. pepo. Our results indicate preference contrasts between the two agriculturally relevant subspecies: C. pepo subsp. texana and C. pepo subsp. pepo. Plants of C. pepo subsp. pepo were more strongly preferred than C. pepo subsp. texana plants. This structure of beetle preference in C. pepo will allow plant breeders and entomologists to better focus research efforts on host plant non-preference to control striped cucumber beetles.

  1. Gauge unification of basic forces particularly of gravitation with strong interactions

    1977-01-01

    Corresponding to the two known types of gauge theories, Yang-Mills with spin-one mediating particles and Einstein Weyl with spin-two mediating particles, it is speculated that two distinct gauge unifications of the basic forces appear to be taking place. One is the familiar Yang-Mills unification of weak and electromagnetic forces with the strong. The second is the less familiar gauge unification of gravitation with spin-two tensor-dominated aspects of strong interactions. It is proposed that there are strongly interacting spin-two strong gravitons obeying Einstein's equations, and their existence gives a clue to an understanding of the (partial) confinement of quarks, as well as of the concept of hadronic temperature, through the use of Schwarzschild de-Sitter-like partially confining solitonic solutions of the strong gravity Einstein equation

    2014-10-01

    Congenital amusia has been described as a lifelong deficit of music perception and production, notably including amusic individuals' difficulties to recognize a familiar tune without the aid of lyrics. The present study aimed to evaluate whether amusic individuals might have acquired long-term knowledge of familiar music, and to test for the minimal amount of acoustic information necessary to access this knowledge (if any) in amusia. Segments of familiar and unfamiliar instrumental musical pieces were presented with increasing duration (250, 500, 1000 msec etc.), and participants provided familiarity judgments for each segment. Results showed that amusic individuals succeeded in differentiating familiar from unfamiliar excerpts with as little acoustic information as did control participants (i.e., within 500 msec). The findings reveal that amusic individuals have stored musical pieces in long-term memory (LTM), and, together with other recent findings, they suggest that congenital amusia might impair conscious access to music processing rather than music processing per se.

Therefore, the necessity to pay attention to vision rehabilitation for them is strongly felt. The aims of this essay are to define vision rehabilitation and its process in relevant centers (called Low Vision Clinic.The statistic of low vision people is reported and the method of collecting data is described. Standard definition, causes of low vision and related diseases (congenital, heredity, acquired… are explained. In addition, low vision aids and role of test and prescription are discussed. Sometimes ophthalmologists and optometrists can not exactly cure patient to raise their V.A because there is no treatment or drug or ordinary glasses. In these cases the clients should refer to low vision clinic and visit low vision specialist on vision rehabilitation process. After primary evaluation they are tested completely and at the end are prescribed proper low vision aid and also provided with advice in relation to career, education role and training techniques especially in children. At the last part of present dissertation, some examples are provided to show effectiveness of vision rehabilitation and low vision aid among the clients in different countries.

    To understand how prioritization of treatment attributes and treatment choice varies by patient characteristics, we sought to specifically determine how demographic variables affect patient treatment preference. Male patients with urethral stricture disease participated in a choice-based conjoint (CBC) analysis exercise evaluating six treatment attributes associated with internal urethrotomy and urethroplasty. Demographic and past symptom data were collected. Stratified analysis of demographic variables, including age, education, income, was conducted using a mixed effect logistic regression model to evaluate the coefficient size and confidence intervals between the treatments attribute preferences of each strata. 169 patients completed the CBC exercise and were included in our analysis. Overall success of the procedure is the most important treatment attribute to patients and this persists across strata. Older patients (≥65) express preferences for better success rates and fewer future procedures, whereas younger patients prefer a less invasive approach and are more willing to accept additional procedures if needed. Patients with lower levels of education preferred open reconstruction and had a stronger preference against multiple future procedures, whereas those with higher levels of education preferred endoscopic treatment and had a less strong preference against multiple future procedures. Low-income individuals express statistically significant stronger negative preferences against high copay costs compared to high-income individuals. These results can help to inform physicians' counseling about surgical management of urethral stricture disease to better align patient preferences with treatment selection and encourage shared decision making.

    The study examined the coaching preferences of 80 male and 80 female athletes, as measured by the Leadership Scale for Sports (Chelladurai and Saleh, 1978, 1980). In addition, it attempted to assess the applicability to sport of the Life-cycle and Path-goal theories of leadership. Comparisons between groups were made on the basis of sex, age, and type of sport. A MANOVA indicated that athletes in independent sports preferred more democratic behaviour (p less than .001) and less autocratic behaviour (p = .028) than athletes in interdependent sports. No differences in coaching preferences were found which could be attributed to the age or sex of the athlete, or the variability of the sports task. These results partially supported the Path-goal theory, but did not support the Life-cycle theory. Athletes of all groups tended to favour coaches who displayed training behaviour and rewarding behaviour "often", democratic behaviour and social support behaviour "occasionally", and autocratic behaviour "seldom". This consistency may be a useful finding for those organizations and institutions interested in preparing coaches.

    Full Text Available Como en otros países de América Latina y del Caribe, sin mencionar el resto del mundo, la estructura de vida familiar en Costa Rica ha cambiado en décadas recientes. El matrimonio ha decaído, el divorcio y la separación aumentan, se incrementan los nacimientos fuera del matrimonio y en un número creciente de hogares las mujeres son jefas de hogar. Tanto a nivel nacional como internacional estas tendencias han sido consideradas como indicadores de una “desintegración familiar”. Esto a su vez con frecuencia ha causado preocupación, especialmente en relación a posibles amenazas al bienestar y desarrollo de los niños. Si bien estas preocupaciones sobre la ruptura familiar han sido expuestas en los medios de comunicación, en informes oficiales y en declaraciones de instituciones religiosas, poco se conoce sobre las vivencias de las personas sobre estos cambios. ¿ Hasta qué punto las personas perciben los cambios en la organización familiar y si es así, a qué los atribuyen? ¿Se podría pensar que los cambios identificados están llevando al “colapso familiar” ?, y ¿Hasta qué punto son tales interpretaciones compartidas por diferentes grupos en términos de género, edad y situación socioeconómica?Este artículo plantea algunas respuestas a estas inquietudes con base en entrevistas individuales y grupos focales de discusión. Se trabajó con 176 hombres y mujeres de bajo y mediano ingreso, de diferentes edades en la provincia de Guanacaste, Costa Rica. Una de las principales conclusiones es que si bien algunos estilos en la vida familiar se perciben como posibilitadoras de condiciones más flexibles y equitativas, otras se consideran como debilitadoras de la unidad familiar. Además, las preocupaciones sobre la “desintegración familiar” son particularmente comunes en los hombres adultos, a pesar de que ellos han estado históricamente menos comprometidos en la vida familiar que las mujeres.

    2006-01-01

    In the amnesia literature, disagreement exists over whether anterograde amnesia involves recollective-based recognition processes and/or familiarity-based ones depending on whether the anatomical damage is restricted to the hippocampus or also involves adjacent areas, particularly the entorhinal and perirhinal cortices. So far, few patients with well documented anatomical lesions and detailed assessment of recollective and recognition performance have been described. We report a comprehensive neuroanatomical assessment and detailed investigation of the anterograde memory functions of a previously described severe amnesic patient (VC). The results of four previously published neuroradiological investigations (resting PET, qualitative MRIs, volumetric MRI and functional MRI) together with the results of two new investigations (voxel-based morphometry and magnetic resonance spectroscopy) are presented. The consistent finding across these different qualitative and quantitative examinations of VC's brain has shown that there is primarily structural and functional abnormality located selectively in the hippocampus bilaterally. Marked impairments in both verbal and non-verbal recall and recognition standardized memory tests were documented in the context of VC's intact cognitive profile and normal semantic memory. The results of five new experimental recognition memory tests tapping recollection and familiarity using verbal, topographical (buildings and landscapes) and unknown human faces memoranda revealed striking differential effects according to the type of stimuli used. A receiver operating characteristic analysis revealed that VC's recollective- and familiarity-based recognition processes were well preserved for unknown human faces. In contrast, recollective-based recognition for verbal and topographical material was at floor. Familiarity-based recognition was also impaired, significantly below controls for verbal and buildings memoranda and quite weak, although not

    Existing long-term memory (LTM) can boost the number of retained representations over a short delay in visual short-term memory (VSTM). However, it is unclear whether and how prior LTM affects the initial process of transforming fragile sensory inputs into durable VSTM representations (i.e., VSTM consolidation). The consolidation speed hypothesis predicts faster consolidation for familiar relative to unfamiliar stimuli. Alternatively, the perceptual boost hypothesis predicts that the advantage in perceptual processing of familiar stimuli should add a constant boost for familiar stimuli during VSTM consolidation. To test these competing hypotheses, the present study examined how the large variance in participants' prior multimedia experience with Pokémon affected VSTM for Pokémon. In Experiment 1, the amount of time allowed for VSTM consolidation was manipulated by presenting consolidation masks at different intervals after the onset of to-be-remembered Pokémon characters. First-generation Pokémon characters that participants were more familiar with were consolidated faster into VSTM as compared with recent-generation Pokémon characters that participants were less familiar with. These effects were absent in participants who were unfamiliar with both generations of Pokémon. Although familiarity also increased the number of retained Pokémon characters when consolidation was uninterrupted but still incomplete due to insufficient encoding time in Experiment 1, this capacity effect was absent in Experiment 2 when consolidation was allowed to complete with sufficient encoding time. Together, these results support the consolidation speed hypothesis over the perceptual boost hypothesis and highlight the importance of assessing experimental effects on both processing and representation aspects of VSTM.

  2. Black holes a laboratory for testing strong gravity

    CERN Document Server

    Bambi, Cosimo

    2017-01-01

    This textbook introduces the current astrophysical observations of black holes, and discusses the leading techniques to study the strong gravity region around these objects with electromagnetic radiation. More importantly, it provides the basic tools for writing an astrophysical code and testing the Kerr paradigm. Astrophysical black holes are an ideal laboratory for testing strong gravity. According to general relativity, the spacetime geometry around these objects should be well described by the Kerr solution. The electromagnetic radiation emitted by the gas in the inner part of the accretion disk can probe the metric of the strong gravity region and test the Kerr black hole hypothesis. With exercises and examples in each chapter, as well as calculations and analytical details in the appendix, the book is especially useful to the beginners or graduate students who are familiar with general relativity while they do not have any background in astronomy or astrophysics.

  5. Dogs' comprehension of referential emotional expressions: familiar people and familiar emotions are easier.

    Science.gov (United States)

    Merola, I; Prato-Previde, E; Lazzaroni, M; Marshall-Pescini, S

    2014-03-01

    Dogs have been shown to discriminate between human facial expressions, and they seem to use human emotional communication to regulate their behaviour towards an external object/situation. However, it is still not clear (1) whether they just respond to the emotional message received with a corresponding increase/decrease in their level of activation or whether they perceive that the emotional message refers to a specific object, (2) which emotional message they use to modify their behaviour (i.e. whether they are following the positive message or avoiding the negative one) and (3) whether their familiarity with the informant has an effect on the dogs' behaviour. To address these issues, five groups of dogs were tested in two experiments. The first group observed the owner delivering two different emotional messages (happiness and fear) towards two identical objects hidden behind barriers, and the second group observed the owner delivering the same emotional messages but with no-objects present in the room. The third and the fourth groups observed the owner delivering a happy versus a neutral, and a negative versus a neutral emotional message towards the hidden objects. Finally, the fifth group observed a stranger acting like the owner of the first group. When the owner was acting as the informant, dogs seemed to be capable of distinguishing between a fearful and happy emotional expression and preferentially chose to investigate a box eliciting an expression of happiness rather than of fear or neutrality. Dogs, however, seemed to have greater difficulty in distinguishing between the fearful and neutral emotional messages delivered by the owner and between the happy and fearful expressions delivered by the stranger. Results suggest that dogs have learned to associate their owners' positive emotional messages to positive outcomes, and hence use their communicative messages to guide their actions. However, negative emotional messages and those delivered by strangers are

  1. Familiar units prevail over statistical cues in word segmentation.

    Poulin-Charronnat, Bénédicte; Perruchet, Pierre; Tillmann, Barbara; Peereman, Ronald

    2017-09-01

    In language acquisition research, the prevailing position is that listeners exploit statistical cues, in particular transitional probabilities between syllables, to discover words of a language. However, other cues are also involved in word discovery. Assessing the weight learners give to these different cues leads to a better understanding of the processes underlying speech segmentation. The present study evaluated whether adult learners preferentially used known units or statistical cues for segmenting continuous speech. Before the exposure phase, participants were familiarized with part-words of a three-word artificial language. This design allowed the dissociation of the influence of statistical cues and familiar units, with statistical cues favoring word segmentation and familiar units favoring (nonoptimal) part-word segmentation. In Experiment 1, performance in a two-alternative forced choice (2AFC) task between words and part-words revealed part-word segmentation (even though part-words were less cohesive in terms of transitional probabilities and less frequent than words). By contrast, an unfamiliarized group exhibited word segmentation, as usually observed in standard conditions. Experiment 2 used a syllable-detection task to remove the likely contamination of performance by memory and strategy effects in the 2AFC task. Overall, the results suggest that familiar units overrode statistical cues, ultimately questioning the need for computation mechanisms of transitional probabilities (TPs) in natural language speech segmentation.

  3. Visual laterality in dolphins: importance of the familiarity of stimuli

    2012-01-01

    Background Many studies of cerebral asymmetries in different species lead, on the one hand, to a better understanding of the functions of each cerebral hemisphere and, on the other hand, to develop an evolutionary history of hemispheric laterality. Our animal model is particularly interesting because of its original evolutionary path, i.e. return to aquatic life after a terrestrial phase. The rare reports concerning visual laterality of marine mammals investigated mainly discrimination processes. As dolphins are migrant species they are confronted to a changing environment. Being able to categorize new versus familiar objects would allow dolphins a rapid adaptation to novel environments. Visual laterality could be a prerequisite to this adaptability. To date, no study, to our knowledge, has analyzed the environmental factors that could influence their visual laterality. Results We investigated visual laterality expressed spontaneously at the water surface by a group of five common bottlenose dolphins (Tursiops truncatus) in response to various stimuli. The stimuli presented ranged from very familiar objects (known and manipulated previously) to familiar objects (known but never manipulated) to unfamiliar objects (unknown, never seen previously). At the group level, dolphins used their left eye to observe very familiar objects and their right eye to observe unfamiliar objects. However, eyes are used indifferently to observe familiar objects with intermediate valence. Conclusion Our results suggest different visual cerebral processes based either on the global shape of well-known objects or on local details of unknown objects. Moreover, the manipulation of an object appears necessary for these dolphins to construct a global representation of an object enabling its immediate categorization for subsequent use. Our experimental results pointed out some cognitive capacities of dolphins which might be crucial for their wild life given their fission-fusion social system

    Full Text Available ABSTRACT: A lot of people live situations of mental sickness, from psychotic character, that can cause suffering both for the sick and his family. We believe that try this situation means to live with limitations and wearings in the familiar everyday, what makes difficult the living with the psychotic person. Considering these aspects, this research has the purpose of knowing the familiar perception about his living with a psychotic bearer person. It is about a qualitative, explorative and descriptive study, developed in a northwest city of Rio Grande do Sul state, called Ijuí. The people of the investigation are composed of five psychotic’s parents, which frequent the socioterapy group in Gloria district. The information collection happened trough open interviews, recorded and wrote out at all. The analysis of the obtained data followed MINAYO’s (2002 methodological proposition. By the contained information in the stud’s social actor’s declarations, emerged three thematic with a similar nucleus of thoughts. On first thematic, we discussed about the difficulties faced by the familiars in the living with the psychotic in the moment he has the acute symptoms. On the second thematic, we talked about the medical question as bring a therapeutic element that helps the mental sick to keep stable., becoming better the familiars life. The third thematic shows the family conception about mental sickness. With this research we concluded that the living with a mental sick person is taxing for the familiar and, sometimes, there are difficulties to understand the symptoms showed by the sick person. Besides that, the family considers the medication one of the most important possibilities of intervention in the psychotic’s therapy, what is reinforced by the health team that leads with these people.

  6. Odor-based recognition of familiar and related conspecifics: a first test conducted on captive Humboldt penguins (Spheniscus humboldti.

    Directory of Open Access Journals (Sweden)

    Heather R Coffin

    Full Text Available Studies of kin recognition in birds have largely focused on parent-offspring recognition using auditory or visual discrimination. Recent studies indicate that birds use odors during social and familial interactions and possibly for mate choice, suggesting olfactory cues may mediate kin recognition as well. Here, we show that Humboldt penguins (Spheniscus humboldti, a natally philopatric species with lifetime monogamy, discriminate between familiar and unfamiliar non-kin odors (using prior association and between unfamiliar kin and non-kin odors (using phenotype matching. Penguins preferred familiar non-kin odors, which may be associated with the recognition of nest mates and colony mates and with locating burrows at night after foraging. In tests of kin recognition, penguins preferred unfamiliar non-kin odors. Penguins may have perceived non-kin odors as novel because they did not match the birds' recognition templates. Phenotype matching is likely the primary mechanism for kin recognition within the colony to avoid inbreeding. To our knowledge this is the first study to provide evidence of odor-based kin discrimination in a bird.

  7. Critical period for acoustic preference in mice.

    Preference behaviors are often established during early life, but the underlying neural circuit mechanisms remain unknown. Adapting a unique nesting behavior assay, we confirmed a "critical period" for developing music preference in C57BL/6 mice. Early music exposure between postnatal days 15 and 24 reversed their innate bias for silent shelter, which typically could not be altered in adulthood. Instead, exposing adult mice treated acutely with valproic acid or carrying a targeted deletion of the Nogo receptor (NgR(-/-)) unmasked a strong plasticity of preference consistent with a reopening of the critical period as seen in other systems. Imaging of cFos expression revealed a prominent neuronal activation in response to the exposed music in the prelimbic and infralimbic medial prefrontal cortex only under conditions of open plasticity. Neither behavioral changes nor selective medial prefrontal cortex activation was observed in response to pure tone exposure, indicating a music-specific effect. Open-field center crossings were increased concomitant with shifts in music preference, suggesting a potential anxiolytic effect. Thus, music may offer both a unique window into the emotional state of mice and a potentially efficient assay for molecular "brakes" on critical period plasticity common to sensory and higher order brain areas.

    2001-01-01

    For START III level forces, strike allocations and magnitudes vary little with L, but first strike costs vary directly with L, which means that for K reflecting a preference for the survival of high value targets over their destruction and a preference for high value over military targets, the costs of action are far greater than those of inaction for a wide range of values of damage preference L. Thus, if both sides have much greater preferences for the survival of their high value targets than for military targets or destruction, they do not see a net incentive to strike, and crises are terminated by inaction. Recent decades suggest strong preferences for the survival of high value and that this has contributed to the lack of direct conflict during that period

    2013-06-01

    Although empirical research on aesthetics has had some success in explaining the average preferences of groups of observers, relatively little is known about individual differences in preference, and especially about how such differences might covary across different domains. In this study, we identified a new factor underlying aesthetic response-preference for harmonious stimuli-and examined how it varies over four domains (color, shape, spatial location, and music) across individuals with different levels of training in art and music. We found that individual preferences for harmony are strongly correlated across all four dimensions tested and decrease consistently with training in the relevant aesthetic domains. Confirmatory factor analysis revealed that cross-domain preference for harmony is well-represented as a single, unified factor, with effects separate from those of training and of common personality measures.

    The purpose of this study was to determine the familiarity with and stated advocacy of Healthy People 2010 objectives by member doctors of the Mississippi Chiropractic Association. Peer experts established face validity of a questionnaire regarding the Leading Health Indicators. This survey was distributed to 157 Mississippi Chiropractic Association members in 2009 during a conference and a follow-up by postal mail. Most doctors of chiropractic in the sample (n = 68, or 43% response) consider themselves wellness-oriented health care providers. Forty-two percent had read, 29% had not read, and another 29% were unsure whether they had read the Healthy People 2010 national objectives. Almost half (44%) strongly or somewhat agreed that their office practice reflects support for the Healthy People 2010 objective. In contrast, 27% disagree and 29% were unsure if their practice reflects the Healthy People 2010 objectives. There were differences between support and practice behaviors for some of the objectives. Chiropractors who have read the objectives tend to be more supportive of the national goals. Doctors of chiropractic in this sample are supportive of most Leading Health Indicators, and the majority reports that they incorporate these public health goals into their practices. Familiarity with reading the Health People objectives seems to be related to reported practice behaviors. There is a need to improve the percentage of practicing doctors of chiropractic who are familiar with Healthy People objectives. Future health education initiatives may assist doctors of chiropractic in further incorporating public health objectives into their practice behaviors and improving quality health care.

    In order to investigate stimulus-related and task-related electrophysiological activity relevant for face processing, event-related potentials (ERPs) from 58 electrodes at standard EEG sites were recorded while subjects performed a simple visual discrimination (control) task, in addition to various face processing tasks: recognition of previously learned faces and gender decision on familiar and unfamiliar faces. Three electrophysiological components or dipolar complex were recorded in all subjects: an occipital early component (P1, around 110 ms); a vertex positive potential (VPP; around 158 ms) which appeared to be specific to faces; and a negative central component, N2 (around 230 ms). Parametric analysis and source localization were applied to these components by means of a single-subject analysis methodology. No effect of familiarity was observed on any of these early component. While the VPP appears to be independent of the kind of processing performed, face task modulations of the early P1 and the N2 were observed, with a higher amplitude for the recognition than for the gender discrimination task. An attentional modulation of early visual areas is proposed for the first effect (P1 modulation), while the N2 seems to be related to general visual memory processing. This study strongly suggests that the VPP reflects an early visual stage of face processing in the fusiform gyrus that is strictly stimulus-related and independent of familiarity. It also shows that source localization algorithms may give reliable solutions on single subject averages for early visual components despite high inter-subject variability of the surface characteristics of ERPs.

    The human voice is described in dialogic linguistics as an embodiment of self in a social context, contributing to expression, perception and mutual exchange of self, consciousness, inner life, and personhood. While these approaches are subjective and arise from phenomenological perspectives, scientific facts about personal vocal identity, and its role in biological development, support these views. It is our purpose to review studies of the biology of personal vocal identity -- the familiar voice pattern-- as providing an empirical foundation for the view that the human voice is an embodiment of self in the social context. Recent developments in the biology and evolution of communication are concordant with these notions, revealing that familiar voice recognition (also known as vocal identity recognition or individual vocal recognition) or contributed to survival in the earliest vocalizing species. Contemporary ethology documents the crucial role of familiar voices across animal species in signaling and perceiving internal states and personal identities. Neuropsychological studies of voice reveal multimodal cerebral associations arising across brain structures involved in memory, emotion, attention, and arousal in vocal perception and production, such that the voice represents the whole person. Although its roots are in evolutionary biology, human competence for processing layered social and personal meanings in the voice, as well as personal identity in a large repertory of familiar voice patterns, has achieved an immense sophistication.

    There is growing interest in using zebrafish (Danio rerio) as a model of neurodegenerative disorders such as Alzheimer's disease. A zebrafish model of tauopathies has recently been developed and characterized in terms of presence of the pathological hallmarks (i.e., neurofibrillary tangles and cell death). However, it is also necessary to validate these models for function by assessing learning and memory. The majority of tools to assess memory and learning in animal models involve visual stimuli, including color preference. The color preference of zebrafish has received little attention. To validate zebrafish as a model for color-associated-learning and memory, it is necessary to evaluate its natural preferences or any pre-existing biases towards specific colors. In the present study, we have used four different colors (red, yellow, green, and blue) to test natural color preferences of the zebrafish using two procedures: Place preference and T-maze. Results from both experiments indicate a strong aversion toward blue color relative to all other colors (red, yellow, and green) when tested in combinations. No preferences or biases were found among reds, yellows, and greens in the place preference procedure. However, red and green were equally preferred and both were preferred over yellow by zebrafish in the T-maze procedure. The results from the present study show a strong aversion towards blue color compared to red, green, and yellow, with yellow being less preferred relative to red and green. The findings from this study may underpin any further designing of color-based learning and memory paradigms or experiments involving aversion, anxiety, or fear in the zebrafish.

    Full Text Available Competition in global pork markets has increased as trade barriers have opened as a result of free trade agreements. Japanese prefer both loin and Boston butt, while Chinese prefer pork offal. Frozen pork has increased in terms of imports into China. Japanese consumers consider pork meat origin along with pork price when making purchase decisions. While the Chinese prefer a strong tasting pork product, South Korean consumers show very strong preferences to pork that is higher in fat. Therefore, South Korean consumers have a higher demand for pork belly and Boston butt. Consequently, the supply and demand of pork in Korea is hardly met, which means that importation of high fat parts is inevitable. In Korea there is lower preference toward low fat parts such as loin, picnic shoulder, and ham. During the economic depression in South Korea there have been observable changes in consumer preferences. There remains steep competition among the pork exporting countries in terms of gaining share in the international pork market. If specific consumer preferences would be considered carefully, there is the possibility to increase the amount of pork exported to these countries.

    2003-10-01

    This research questioned the proposition that corporate familiarity is positively associated with firm reputation. Student images of familiar and unfamiliar Fortune 500 corporations were examined in 4 experiments. The results suggested that, consistent with behavioral decision theory and attitude theory, highly familiar corporations provide information that is more compatible with the tasks of both admiring and condemning than less familiar corporations. Furthermore, the judgment context may determine whether positive or negative judgments are reported about familiar companies. The notion that people can simultaneously hold contradictory images of well-known firms may help to explain the inconsistent findings on the relation between familiarity and reputation.

    A descriptive exploratory study was conducted to gain an understanding of public perceptions of physical activity guidelines and to discover what formats appeal to participants. Canada's Physical Activity Guide (CPAG) was used as an example of such guidelines. Data were collected from 22 participants in five focus groups (composed of female undergraduate students, female office workers, male office workers, participants in a Type II diabetes rehabilitation program, and participants in a cardiovascular rehabilitation program). Cross-case qualitative analyses were conducted. Six themes emerged under the general categories of familiarity and preferences for PA promotional materials. In terms of familiarity, participants lacked awareness of CPAG and criticized its format. In terms of preferences, participants encouraged the use of stylistically similar messaging to those used by commercial advertisers, wanted personal stories, Internet-based media, and the use of celebrities' success stories. There was little awareness of CPAG and the current format was unappealing.

    This pilot study examined the feasibility, acceptability, and preliminary outcomes of a linguistically and culturally adapted intervention for immigrant Latina mothers with depression and their families. Fortalezas Familiares (Family Strengths) is a community-based, 12-week, multifamily group intervention that aims to increase communication about family processes leading up to and affected by the mother's depression, build child coping and efficacy, enhance parenting competence and skills, and promote cultural and social assets within the family. In terms of feasibility, of 16 families who enrolled and participated in the intervention, 13 families attended more than 90% of meetings and completed the intervention. Posttests reported positive changes following the intervention, including improved psychological functioning, increased family and marital support, and enhanced family functioning, as reported by mothers and other caregivers. Mothers also reported decreased conduct and hyperactivity problems among their children. Children reported positive changes in their psychological functioning and coping, parenting warmth and acceptance, and overall family functioning. Postintervention focus groups and surveys measuring acceptability revealed families' satisfaction with the intervention and suggested areas of improvement. We discuss similarities and differences in outcomes between the adapted intervention, Fortalezas Familiares, and the original intervention, Keeping Families Strong, and propose future areas of intervention adaptation and development. © FPI, Inc.

    High- and low-avoidance Roman inbred rat strains (RHA-I, RLA-I) were selected for extreme differences in two-way active avoidance. RHA-I rats also express less anxiety than RLA-I rats. This study compared male Roman rats in ethanol preference and sensation/novelty seeking. Rats were first exposed in counterbalanced order to the hole-board test (forced exposure to novelty) and the Y-maze and emergence tests (free choice between novel and familiar locations). Then, rats were tested in 24-h, two-bottle preference tests with water in one bottle and ethanol (2, 4, 6, 8, or 10% in successive days). Compared to RLA-I rats, RHA-I rats showed (1) higher frequency and time in head dipping, (2) higher activity, and (3) lower frequency of rearing and grooming in the hole-board test, and (4) remained in the novel arm longer in the Y-maze test. No strain differences were observed in the emergence test. RHA-I rats exhibited higher preference for and consumed more ethanol than RLA-I rats at all concentrations. However, both strains preferred ethanol over water for 2-4% concentrations, but water over ethanol for 6-10% concentrations. Factorial analysis with all the rats pooled identified a two-factor solution, one grouping preferred ethanol concentrations (2-4%) with head dipping and grooming in the hole board, and another factor grouping the nonpreferred ethanol concentrations (6-10%) with activity in the hole board and novel-arm time in the Y-maze test. These results show that preference for ethanol is associated with different aspects of behavior measured in sensation/novelty-seeking tests. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available First analyses of the development of agriculture capitalism have indicated that modernization presided by the logic of urban industry would make this activity in small production units impossible. Contemporary analyses have confirmed this thesis. These small units of production that have invested strongly in modernizing their technical basis, and targeted their production exclusively to the market, have not had any satisfactory economic returns to reduce their debts, being constantly in crisis and dependent on state politics. On the other hand, those familiar units , where farmers have learned how to balance traditional with modern knowledge and to connect production for self-consumption to market production, have developed greater capacity for surviving the crisis that usually hit the market. As primeiras análises acerca do desenvolvimento do capitalismo na agricultura apontavam que uma modernização presidida pela lógica da indústria urbana inviabilizaria a atividade em pequenas unidades de produção. Análises contemporâneas têm corroborado essa tese. Aquelas pequenas unidades de produção que mergulharam a fundo na modernização das suas bases técnicas, com produção voltada exclusivamente para o mercado, não têm obtido retornos econômicos satisfatórios para amortizar suas dívidas, pois estão constantemente em crise e dependem da política estatal. Contrariamente, aquelas unidades familiares nas quais os agricultores têm sabido equilibrar o conhecimento tradicional com o moderno, e aliam a produção para o autoconsumo à produção para o mercado, têm tido maior capacidade para sobreviver às crises que costumeiramente se abatem sobre o mercado.

    The objective of this study was to determine whether reaching for objects with varying levels of preference associated with them elicited influenced motor control in a reaching task. Forty healthy adults were asked to reach for seven different types of candy, which they ranked by personal preference from being the most preferred to the least preferred. In this repeated measures design, data were analyzed on 39 participants who tended to demonstrate greater movement efficiency in movement time and movement units when reaching for candy in which they associated with greater preference (p .0167), these dependent variables appeared to trend in the direction of similar movement efficiency. Therapists can use this knowledge to help guide clinical reasoning when designing treatment plans and approaches. Future research is needed to further examine intensity along the continuum of preference and its implications for occupational therapy practice.

    Meningococcal disease is rare but can cause death or disabilities. Although the Advisory Committee on Immunization Practices has recommended meningococcal vaccination for at-risk children aged 9 through 23 months, it has not endorsed universal vaccination. Health insurance payments for the vaccination of children who are not at risk are likely to be limited. Use of infant meningococcal vaccines by these families will thus depend on the preferences of physicians who might recommend vaccination to parents, as well as parents' preferences. To quantify pediatricians' preferences for specific features of hypothetical infant meningococcal vaccines. A sample of pediatricians (n = 216) completed a Web-enabled, discrete choice experiment survey in which respondents chose between pairs of hypothetical vaccines in a series of trade-off questions. The questions described vaccines with six attributes. A random-parameters logit regression model was used to estimate the relative importance weights physicians place on vaccine features. These weights were used to calculate the predicted probability that a physician chooses hypothetical vaccines with given characteristics. Pediatricians' choices indicated that increases in vaccine effectiveness were among the most important factors in their vaccine recommendations, followed by increases in the number of injections. The age at which protection begins and the number of additional office visits were less important. Whether a booster was required after 5 years was the least important factor in vaccine recommendations. The results suggest that virtually all (99.9%) physicians in the sample would recommend a vaccine even with the least-preferred features rather than no infant meningococcal vaccine. Physicians' responses indicate a strong preference for infant meningococcal vaccination. Copyright © 2015 International Society for Pharmacoeconomics and Outcomes Research (ISPOR).

MÉTODOS: Participaram 20 díades de crianças com gagueira e familiares. Os procedimentos foram realizados em três etapas: avaliação da fluência, orientações familiares e reavaliação da fluência. A avaliação inicial da fluência foi realizada para caracterizar a tipologia e a frequência das disfluências antes das orientações. A orientação familiar foi realizada em duas sessões, enfatizando os comportamentos verbais e não verbais da família que podem promover a fluência na criança. A reavaliação da fluência ocorreu depois de trinta dias, utilizando-se os mesmos procedimentos da avaliação inicial. Foi aplicado o Teste dos Postos Sinalizados de Wilcoxon, para medir o grau de significância da diferença entre as informações obtidas nas duas fases. RESULTADOS: No que se refere à tipologia, a análise comparativa das duas avaliações mostrou que, dentre os seis tipos de disfluências comuns, quatro diminuíram, e, dentre os seis tipos de disfluências gagas, cinco apresentaram redução. No que se refere à frequência das rupturas, 70% das crianças tiveram uma diminuição na porcentagem de descontinuidade de fala, e 80% no total de rupturas gagas. CONCLUSÃO: A orientação fonoaudiológica realizada com familiares de crianças com gagueira favoreceu a promoção da fluência na fala da criança, mostrando-se relevante na área da fluência infantil.PURPOSE: To determine the contribution of short-term familiar counseling in the speech fluency of children who stutter.

    This study investigated the association of music preferences with tobacco smoking in a group of 152 high school and college students. Both the questionnaire and the listening survey indicated a higher preference for music associated with anxiety and depressed mood among smokers. These findings may reflect a common etiology of tobacco addiction and a specific type of music preferences. To elucidate this phenomenon further studies are needed.

    Full Text Available Many people are encountered with finding the best way to reach to their destination. One definition for wayfinding is “the act of travelling to the destination by continuous processes of making route-choices whilst evaluating previous spatial decisions against stable cognition of the environment.  General understanding and keen appraisal of the environment can aid decision-making process of how to navigate around an area in the form of mental schemas. However, having a level of familiarity and attachment to a place is the underlying factor. The study is aimed at evaluating what is the level of familiarity of people and what is their attachment to notable landmarks in the town of Muar, Malaysia. To do so, the traditional survey analysis with the focus on data set that is attributed to a specific phenomenon and the quantifiable variable using statistical analysis on the tabularized format is undertaken.

    The calculation decides the integrity of the safety latch that will hold the strong-back to the pump during lifting. The safety latch will be welded to the strong-back and will latch to a 1.5-in. dia cantilever rod welded to the pump baseplate. The static and dynamic analysis shows that the safety latch will hold the strong-back to the pump if the friction clamps fail and the pump become free from the strong-back. Thus, the safety latch will meet the requirements of the Lifting and Rigging Manual for under the hook lifting for static loading; it can withstand shock loads from the strong-back falling 0.25 inch

    The calculation decides the integrity of the safety latch that will hold the strong-back to the pump during lifting. The safety latch will be welded to the strong-back and will latch to a 1.5-in. dia cantilever rod welded to the pump baseplate. The static and dynamic analysis shows that the safety latch will hold the strong-back to the pump if the friction clamps fail and the pump become free from the strong-back. Thus, the safety latch will meet the requirements of the Lifting and Rigging Manual for under the hook lifting for static loading; it can withstand shock loads from the strong-back falling 0.25 inch.

  19. Preference formation and institutional change

    Full Text Available This essay critically analyses how historical institutionalists and rational choice scholars study institutional stability and change. Special attention is paid to the thorny issued of how political actors’ preferences are formed, with historical institutionalists considering preferences as endogenously formed, and rational choice analysts postulating that preferences are fixed and exogenous. An argument is made in favour of the perspective that considers preferences as being formed within the functioning of the political system over time, endogenously. The essay also proposes the incorporation of ideas and non-decisions as tools to elucidate processes of change.

  1. Bodystorming: effects of collaboration and familiarity on improvising contemporary dance.

    In contemporary dance, cognitive events are not necessarily restricted "to the skin or skull of an individual" (Hutchins in Int Encycl Soc Behav Sci 2068-2072, 2001) but distributed across dancers during collaborative improvisation. There is some experimental evidence of greater output when people perform problem-solving tasks alone. However, when a task is challenging and paired participants are familiar with each other, pairwise and emergent outcomes are more plentiful than solo outcomes. We investigate these factors in the context of dance with the broad hypothesis that innovation is enhanced when dancers improvise together compared with when they improvise alone. Dancers (N = 10) in a professional company improvised for 2 min alone and then with another dancer. Dancer familiarity (familiar, unfamiliar) and task (expressive, non-expressive) were crossed (within-subjects). The improvisations were video-recorded over 2 h in the dancers' usual improvisation space. After each improvisation, the dancers: stated the number of movement ideas expressed and rated task ease, satisfaction, interest, novelty, originality and clarity. In both tasks, there was a tendency for self-report of a greater number of movement ideas expressed in familiar and unfamiliar pairs than alone. Ratings of task ease, satisfaction, interest, clarity, etc. were slightly higher in the unfamiliar pair condition. In the non-expressive task, ratings of the task were higher in pairs (M = 3.02, SD 0.82) than in the solo (M = 2.67, SD 0.96) condition. Distributed creativity, relational cognition and social facilitation are used to interpret the results.

We believe that try this situation means to live with limitations and wearings in thefamiliar everyday, what makes difficult the living with the psychotic person. Considering these aspects, thisresearch has the purpose of knowing the familiar perception about his living with a psychotic bearer person. It isabout a qualitative, explorative and descriptive study, developed in a northwest city of Rio Grande do Sul state,called Ijuí. The people of the investigation are composed of five psychotic’s parents, which frequent the socioterapygroup in Gloria district. The information collection happened trough open interviews, recorded and wrote out at all.The analysis of the obtained data followed MINAYO’s (2002 methodological proposition. By the containedinformation in the stud’s social actor’s declarations, emerged three thematic with a similar nucleus of thoughts. Onfirst thematic, we discussed about the difficulties faced by the familiars in the living with the psychotic in themoment he has the acute symptoms. On the second thematic, we talked about the medical question as bring atherapeutic element that helps the mental sick to keep stable., becoming better the familiars life. The third thematicshows the family conception about mental sickness. With this research we concluded that the living with a mentalsick person is taxing for the familiar and, sometimes, there are difficulties to understand the symptoms showed bythe sick person. Besides that, the family considers the medication one of the most important possibilities ofintervention in the psychotic’s therapy, what is reinforced by the health team that leads with these people.

    2016-11-01

    Mouse pups (Mus musculus) placed on the midline of a mesh floor suspended over an empty area bounded by 2 odor fields, 1 containing homecage bedding and the other clean bedding, preferentially selected the homecage area when tested on postnatal day (PD) 5, 10, or 12. PD5 pups given a choice of homecage bedding versus age-matched bedding from another litter showed no discrimination, whereas PD10/12 pups preferred own home odors. To test whether such home orientation can be shaped by experience, pups were placed for 2 hrs on PDs 8 and 9 with either a lactating dam, a nonlactating foster dam or a warm tube bearing 1 of 2 novel odors. Other pups were similarly exposed to scented gauze to test whether mere exposure (familiarization) to an odor could induce a preference. Pups naïve to both test odors and those familiar with 1 odor showed no preference for either odor on PD10. Pups placed with a lactating dam spent significantly more time over the conditioned odor. Moreover, pups placed with the nonlactating dams or the warm tube also preferred the conditioned odor, indicating that the preference can be attributed association with non-nutritive, thermotactile cues.

    Several studies have shown that preferences can be strongly modulated by cognitive processes such as decision making and choices. However, it is still unclear whether choices can influence preferences of sensory stimuli implicitly. This question was addressed here by asking participants to evaluate odors, to choose their preferred odors within pairs, to reevaluate the odors, and to perform an unexpected memory test. Results revealed, for the first time in the study of olfaction, the existence of postchoice preference changes, in the sense of an overvaluation of chosen odors and a devaluation of rejected ones, even when choices were forgotten. These results suggest that chemosensory preferences can be modulated by explicit choices and that such modulation might rely on implicit mechanisms. This finding rules out any explanation of postchoice preference changes in terms of experimental demand and strongly challenges the classical cognitive-dissonance-reduction account of such preference changes.

  8. A familiar font drives early emotional effects in word recognition.

    Kuchinke, Lars; Krause, Beatrix; Fritsch, Nathalie; Briesemeister, Benny B

    2014-10-01

    The emotional connotation of a word is known to shift the process of word recognition. Using the electroencephalographic event-related potentials (ERPs) approach it has been documented that early attentional processing of high-arousing negative words is shifted at a stage of processing where a presented word cannot have been fully identified. Contextual learning has been discussed to contribute to these effects. The present study shows that a manipulation of the familiarity with a word's shape interferes with these earliest emotional ERP effects. Presenting high-arousing negative and neutral words in a familiar or an unfamiliar font results in very early emotion differences only in case of familiar shapes, whereas later processing stages reveal similar emotional effects in both font conditions. Because these early emotion-related differences predict later behavioral differences, it is suggested that contextual learning of emotional valence comprises more visual features than previously expected to guide early visual-sensory processing.

    Los Alamos National Laboratory (LANL, the Laboratory, or the Lab) conducts familiarization tours for Los Alamos County Fire Department (LAFD) personnel at the Strategic Computing Complex (SCC), TA-03-2327, and the Nonproliferation & International Security Complex (NISC), TA-03-2322. These tours are official LANL business; their purpose is to orient the firefighters to the SCC and the NISC so that they can respond efficiently and quickly to a variety of emergency situations. The tour includes ingress and egress of the buildings, layout and organization of the buildings, evacuation procedures, and areas of concern to emergency responders within these buildings. LAFD firefighters have the training, skills, and abilities to perform these emergency responder tasks; other LANL personnel who have the required clearance level cannot perform these tasks. This handout provides details of the information, along with maps and diagrams, to be presented during the familiarization tours. The report will be distributed to the trainees at the time of the tour. A corresponding checklist will also be used as guidance during the familiarization tours to ensure that all required information is presented to the LAFD personnel.

Los flujos de dinero entre ambos territorios se producen en el seno de la mayoría de las familias, tienen una frecuencia muy variada y los montos involucrados son modestos. Los testimonios recogidos entre las personas que mandan dinero a sus familiares en Colombia revelan que, para la mayoría de ellas, la frecuencia y los montos que envían se reducen una vez que se han asentado en la provincia de Quebec, en comparación con la situación previa al exilio. Para muchos de ellos, el papel de proveedor económico que desempeñaban dentro de su familia se ha reducido de manera considerable; y para otros inclusive desaparece. De manera general, se puede afirmar que no se producen cambios importantes en lo que se refiere a las intenciones de las personas en colaborar económicamente con sus familiares al salir en exilio. Los cambios se producen en las posibilidades concretas de hacerlo, las cuales disminuyen o desaparecen.

    The present study concerned how the acquisition of social information, specifically knowledge about personal characteristics, influences young children's memory and suggestibility. Effects of two sources of knowledge about a target person were systematically examined: familiarity and stereotypes. Children, aged 4-5 and 7-9 years (N = 145), were randomly assigned, per age group, to experimental conditions based on a familiarity (6 hours vs. no prior exposure) × stereotype (negative depiction as messy and clumsy vs. no stereotype) factorial design. Children then watched the target person engage in a target event (a series of contests) at a preschool ("Camp Ingrid"). The children's memory and suggestibility about the target person and target event were tested after a delay of 2 weeks. Results indicated that the negative stereotype resulted in an increase in children's correct responses both to free-recall stereotype-related questions (when children were unfamiliar with the target person) and to closed-ended questions overall (for younger children). However, the stereotype was associated with greater error to stereotype-related closed-ended questions. Moreover, familiarity increased children's accuracy to closed-ended questions. Implications for theory and application are discussed. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

    Patients suffering from age-related macular degeneration (AMD) are rarely actively involved in decision-making, despite facing preference-sensitive treatment decisions. This paper presents a qualitative study to prepare quantitative preference elicitation in AMD patients. The aims of this study were (1) to gain familiarity with and learn about the special requirements of the AMD patient population for quantitative data collection; and (2) to select/refine patient-relevant treatment attributes and levels, and gain insights into preference structures. Semi-structured focus group interviews were performed. An interview guide including preselected categories in the form of seven potentially patient-relevant treatment attributes was followed. To identify the most patient-relevant treatment attributes, a ranking exercise was performed. Deductive content analyses were done by two independent reviewers for each attribute to derive subcategories (potential levels of attributes) and depict preference trends. The focus group interviews included 21 patients. The interviews revealed that quantitative preference surveys in this population will have to be interviewer assisted to make the survey feasible for patients. The five most patient-relevant attributes were the effect on visual function [ranking score (RS): 139], injection frequency (RS: 101), approval status (RS: 83), side effects (RS: 79), and monitoring frequency (RS: 76). Attribute and level refinement was based on patients' statements. Preference trends and dependencies between attributes informed the quantitative instrument design. This study suggests that qualitative research is a very helpful step to prepare the design and administration of quantitative preference elicitation instruments. It especially facilitated familiarization with the target population and its preferences, and it supported attribute/level refinement.

    Sexual partner preferences can be strengthened, weakened or even drastically modified via Pavlovian conditioning. For example, conditioned same-sex partner preference develops in sexually-naïve male rats that undergo same-sex cohabitation under the effects of quinpirole (QNP, D2 agonist). Here, we assessed the effect of prior heterosexual experience on the probability to develop a conditioned same-sex preference. Naïve or Sexually-experienced males received either Saline or QNP and cohabited during 24h with a male partner that bore almond scent on the back as conditioned stimulus. This was repeated every 4days for a total of three trials and resulted in four groups (Saline-naïve, Saline-experienced, QNP-naïve, QNP-experienced). Social and sexual preference were assessed four days after the last conditioning trial in a drug-free test in which experimental males chose between the scented familiar male and a novel sexually receptive female. Results showed that Saline-naïve, Saline-experienced and QNP-experienced displayed a clear preference for the female (opposite-sex). By contrast, only QNP-naïve males displayed a same-sex preference. Accordingly, QNP-experienced males were not affected by the conditioning process and continued to prefer females. We discuss the effects of copulation and D2 agonists on the facilitation and/or disruption of conditioned partner preferences. Copyright © 2017 Elsevier B.V. All rights reserved.

    Titanium (Ti) is a strong silver-gray metal that is highly resistant to corrosion and is chemically inert. It is as strong as steel but 45 percent lighter, and it is twice as strong as aluminum but only 60 percent heavier. Titanium dioxide (TiO2) has a very high refractive index, which means that it has high light-scattering ability. As a result, TiO2 imparts whiteness, opacity, and brightness to many products. ...Because of the unique physical properties of titanium metal and the whiteness provided by TiO2, titanium is now used widely in modern industrial societies.

    Nevertheless the criticism of various economy sectors and international organisms to the production of bio fuels, the Brazilian Government are giving incentives for that production since the year of 2004, when they launched an incentive program for the production of oleaginous species which are the raw material for the production of bio diesel, emphasizing the support to familiar agriculture. However, there are serious questionings about the real contribution of these fuels for the sustainability not only of the planet, but also the population, taking into consideration the possible social and environmental impacts of the implementation of their policies. This paper tries to debate all those problems through the analysis of the possible effects of the Brazilian policies of incentive to the bio diesel production for the family farmers from the semi-arid of the state of Bahia, Brazil. The paper intends to evaluate if this type of production is a real alternative for the sustainability of the familiar agriculture, and if there is another model of more adequate management for the production of oleaginous for bio diesel by the familiar agriculture.

  4. Health, education and time preference.

    van der Pol, Marjon

    2011-08-01

    Education has been shown to be the most important correlate of health. However, the mechanism through which education influences health has been largely unexplained. Grossman argued that education improves health production efficiency. In contrast, Fuchs argued that the association between health and education is not primarily causal but reflects unobserved causes of both outcomes. Instead of education causing better health, some 'third' variables may be related to both education and health. The 'third' variable most frequently mentioned is time preference. The aim of this paper is to investigate the role of time preference in the relationship between education and health. The role of risk attitude is also investigated. The paper exploits a unique data set of households that incorporated stated preference questions eliciting individuals' time preferences. The results show that the effect of education reduces but does not disappear when controlling for individuals' time preferences. Copyright © 2010 John Wiley & Sons, Ltd.

    2017-04-01

    We study short-term recognition of timbre using familiar recorded tones from acoustic instruments and unfamiliar transformed tones that do not readily evoke sound-source categories. Participants indicated whether the timbre of a probe sound matched with one of three previously presented sounds (item recognition). In Exp. 1, musicians better recognised familiar acoustic compared to unfamiliar synthetic sounds, and this advantage was particularly large in the medial serial position. There was a strong correlation between correct rejection rate and the mean perceptual dissimilarity of the probe to the tones from the sequence. Exp. 2 compared musicians' and non-musicians' performance with concurrent articulatory suppression, visual interference, and with a silent control condition. Both suppression tasks disrupted performance by a similar margin, regardless of musical training of participants or type of sounds. Our results suggest that familiarity with sound source categories and attention play important roles in short-term memory for timbre, which rules out accounts solely based on sensory persistence.

    Fertility preference being related to government policy in China, women generally understate their desired family size when questioned directly. A binomial probit model is, therefore, presented to estimate the probability that family-size preferences in Shifang County, Sichuan, China, are understated. The model provides estimates on the percentage of respondent understatement along with the number of children, women of different ages and social characteristics truly desire. Women's preferences for sons versus daughters are also examined. The study found that women desire on average 1/2 more children than that which they state. Understating was in greatest evidence among urban, educated, and younger women more sensitive to the government's 1-child policy. Preference for sons was found to be weaker than expected, yet strong nonetheless in rural areas among women desiring only 1 child. Sons are considered to cause more worry for parents in China due to an aggressive, risk-taking nature. Possible explanations for the decline of son preference include increasing familial costs for sons' betrothment and marriage, changing household structures, and increasing status of and job opportunities for women in Chinese society. In closing, the paper highlights that couples restrict marital fertility out of interest for national prosperity and the welfare of future generations, not personal preference for small families. Were government policy to relax, fertility would rise to preferred levels.

  11. Stevia and Saccharin Preferences in Rats and Mice

    Use of natural noncaloric sweeteners in commercial foods and beverages has expanded recently to include compounds from the plant Stevia rebaudiana. Little is known about the responses of rodents, the animal models for many studies of taste systems and food intake, to stevia sweeteners. In the present experiments, preferences of female Sprague–Dawley rats and C57BL/6J mice for different stevia products were compared with those for the artificial sweetener saccharin. The stevia component rebaudioside A has the most sweetness and least off-tastes to human raters. In ascending concentration tests (48-h sweetener vs. water), rats and mice preferred a high-rebaudioside, low-stevioside extract as strongly as saccharin, but the extract stimulated less overdrinking and was much less preferred to saccharin in direct choice tests. Relative to the extract, mice drank more pure rebaudioside A and showed stronger preferences but still less than those for saccharin. Mice also preferred a commercial mixture of rebaudioside A and erythritol (Truvia). Similar tests of sweet receptor T1R3 knockout mice and brief-access licking tests with normal mice suggested that the preferences were based on sweet taste rather than post-oral effects. The preference response of rodents to stevia sweeteners is notable in view of their minimal response to some other noncaloric sweeteners (aspartame and cyclamate). PMID:20413452

    Elaiosomes of myrmecochorous plant seeds are known to enhance the attraction of diaspore-dispersing ants by serving as a nutritional reward. However, it remained unclear which (nutritional) compounds affect diaspore preferences of ants. We hypothesized that apart from elaiosome/seed-size ratio, volume, and physical surface of diaspores, the quantity and the composition of fatty acids, amino acids, and sugars strongly influence the diaspore preferences of different species. Chemical (nutritional) profiles as well as structural properties of seeds with and without elaiosomes were analyzed and correlated with observed seed choice behavior of ants. Cafeteria experiments in the field confirmed the enhanced attractiveness of elaiosome-bearing seeds for all three ant species tested (Lasius fuliginosus, Myrmica ruginodis, and Temnothorax nylanderi), although seeds lacking elaiosomes also were transported. In multiple-choice cafeteria experiments with simultaneously offered diaspores of 16 plant species with and without elaiosome and with highly varying structural and chemical properties, all three ant species showed distinct preferences for certain diaspore species. Correlation analyses confirmed that the presence of an elaiosome represents the crucial factor that favors ant diaspore dispersal. In addition, the composition and the content of free amino acids, and to varying degrees fatty acids, were found to significantly affect preferences of each ant species, whereas the effect of single fatty acids acting as chemical triggers for diaspore transport by ants, as supposed by several studies, was not confirmed. In conclusion, although at least some diaspore species lacking elaiosomes attract ants for diaspore removal services by presenting nutritional seed coats, the production of elaiosomes seems to provide a worthwhile investment. Elaiosomes ensure rapid diaspore detection and removal due to chemical cue compounds and by offering a highly nutritional food supply, probably

  15. Discrimination of familiar human faces in dogs (Canis familiaris)

    Faces are an important visual category for many taxa, and the human face is no exception to this. Because faces differ in subtle ways and possess many idiosyncratic features, they provide a rich source of perceptual cues. A fair amount of those cues are learned through social interactions and are used for future identification of individual humans. These effects of individual experience can be studied particularly well in hetero-specific face perception. Domestic dogs represent a perfect model in this respect, due to their proved ability to extract important information from the human face in socio-communicative interactions. There is also suggestive evidence that dogs can identify their owner or other familiar human individuals by using visual information from the face. However, most studies have used only dogs’ looking behavior to examine their visual processing of human faces and it has been demonstrated only that dogs can differentiate between familiar and unknown human faces. Here, we examined the dog's ability to discriminate the faces of two familiar persons by active choice (approach and touch). Furthermore, in successive stages of the experiment we investigated how well dogs discriminate humans in different representations by systematically reducing the informational richness and the quality of the stimuli. We found a huge inter-individual and inter-stage variance in performance, indicating differences across dogs in their learning ability as well as their selection of discriminative cues. On a group level, the performance of dogs significantly decreased when they were presented with pictures of human heads after having learned to discriminate the real heads, and when – after relearning – confronted with the same pictures showing only the inner parts of the heads. However, as two dogs quickly mastered all stages, we conclude that dogs are in principle able to discriminate people on the basis of visual information from their faces and by making active

  16. The SNAP Strong Lens Survey

    2005-01-03

    Basic considerations of lens detection and identification indicate that a wide field survey of the types planned for weak lensing and Type Ia SNe with SNAP are close to optimal for the optical detection of strong lenses. Such a ''piggy-back'' survey might be expected even pessimistically to provide a catalogue of a few thousand new strong lenses, with the numbers dominated by systems of faint blue galaxies lensed by foreground ellipticals. After sketching out our strategy for detecting and measuring these galaxy lenses using the SNAP images, we discuss some of the scientific applications of such a large sample of gravitational lenses: in particular we comment on the partition of information between lens structure, the source population properties and cosmology. Understanding this partitioning is key to assessing strong lens cosmography's value as a cosmological probe.

  17. Strong coupling phase in QED

    Existence of a strong coupling phase in QED has been suggested in solutions of the Schwinger-Dyson equation and in Monte Carlo simulation of lattice QED. In this article we recapitulate the previous arguments, and formulate the problem in the modern framework of the renormalization theory, Wilsonian renormalization. This scheme of renormalization gives the best understanding of the basic structure of a field theory especially when it has a multi-phase structure. We resolve some misleading arguments in the previous literature. Then we set up a strategy to attack the strong phase, if any. We describe a trial; a coupled Schwinger-Dyson equation. Possible picture of the strong coupling phase QED is presented. (author)

    Full Text Available According to family resources theory, the empowerment of women caused by the different dimensions of family change during the last decades (deinstitutionalization of the family, female work, higher education, etc has brought about a greater say in the process of negotiation of gender roles inside the family and the couple life. This impowerment of women should have implied also a lower degree of partner violence against women in “modern” family life settings. Based on a survey on violence against women carried out in 1999 in Spain among 20.000 women, the paper analyses using logistic regressions models if different dimensions of family change (female work, cohabitation, among others are associated with lower risks of partner violence against women. Results from such type of analyses show that there is little support to suppose that family change and the corresponding empowerment of women which it implies will bring about a lower risk of partner violence against women.

    Según la teoría de los recursos, la ganancia de recursos de poder por parte de las mujeres derivada de las distintas dimensiones del cambio familiar (desintitucionalización de la familia, incorporación de la mujer al mercado de trabajo, mayor nivel educativo, etc. ha comportado un mayor poder de negociación del contenido de los roles familiares y domésticos. Esta ganancia en recursos de poder debería haberse traducido en una menor violencia conyugal contra las mujeres que viven en uniones “modernas”. A partir de la macroencuesta sobre violencia de género realizada por el Instituto de la Mujer en 1999 se analiza si las distintas dimensiones del cambio familiar están asociadas con un menor riesgo de maltrato. Los resultados obtenidos mediante ajustes de regresión logística indican que el cambio familiar y el correspondiente aumento de poder de negociación de las mujeres no se ha traducido automáticamente en una reducción del riesgo de maltrato.

    2014-02-01

    Food choice and consumption behaviour are influenced by many interacting factors. In this paper we present an empirical effort to enhance understanding of the neophobia-neophilia forces affecting food choice. Starting from the analysis of consumer preferences for some of the most familiar highly processed foods, namely fat-reduced, functional (enriched drinks and yogurt) and ready-to-eat frozen food, our study investigates the role of traditional demographic variables vs attitudes to new food technologies in predicting the consumption behaviour of a sample of Italians buying such products. Consumer attitudes toward food technologies were collected by means of the Food Technology Neophobia Scale (FTNS). Moreover, this paper explicitly analyses the value of the information provided by the FTNS. Underlying the research is the hypothesis that the FTNS may contribute to provide a comprehensive picture of the driving forces behind consumers' behavioural responses towards processed foods which are the end-result of mature technologies. The four FTNS components, once measured and used independently, help clarify the influence on food choices of each neophobia-neophilia force (risk perception and novelty seeking, media influence, own health and environmental concerns) into a single, comprehensive framework.

    2016-03-01

    Adults use cultural markers to discern the structure of the social landscape. Such markers may also influence the social preferences of young children, who tend to conform to their own group and prefer others who do so. However, the forces that propel these preferences are unknown. Here, we use social preferences based on music to investigate these forces in four- and five-year-old children. First, we establish that children prefer other children whose favorite songs are familiar to them. Then we show that this effect depends on shared knowledge: children both prefer others who know songs they themselves know, and avoid others who know songs they do not know, irrespective of the target children's liking of the songs. These results suggest that young children have a remarkably selective sensitivity to shared cultural knowledge. Shared knowledge may be a powerful determinant of children's social preferences, both because it underpins effective communication and because it is conveyed by others through social interactions and therefore can serve as a marker of social group identity.

    Full Text Available Pro-social behaviors are defined as voluntary actions that benefit others. Comparative studies have mostly focused on investigating the presence of pro-sociality across species in an intraspecific context. Taken together, results on both primates and non-primate species indicate that reliance on cooperation may be at work in the selection and maintenance of pro-social sentiments. Dogs appear to be the ideal model when investigating a species’ propensity for pro-sociality in an interspecific context since it has been suggested that as a consequence of domestication, they evolved an underlying temperament encouraging greater propensity to cooperate with human partners. In a recent study, using a food delivery paradigm, dogs were shown to preferentially express pro-social choices towards familiar compared to unfamiliar conspecifics. Using the same set-up and methods in the current study, we investigated dogs’ pro-social preferences towards familiar and unfamiliar human partners. We found that dogs’ pro-social tendencies did not extend to humans and the identity of the human partners did not influence the rate of food delivery. Interestingly, dogs tested with their human partners spent more time gazing at humans, and did so for longer after food consumption had ended than dogs tested with conspecific partners in the initial study. To allow comparability between results from dogs tested with a conspecific and a human partner, the latter were asked not to communicate with dogs in any way. However, this lack of communication from the human may have been aversive to dogs, leading them to cease performing the task earlier compared to the dogs paired with familiar conspecifics in the prior study. This is in line with previous findings suggesting that human communication in such contexts highly affects dogs’ responses. Consequently, we encourage further studies to examine dogs’ pro-social behavior towards humans taking into consideration their

Para a análise dos dados, utilizamos a análise temática, em que depreendemos três categorias temáticas: significado da morte materna, vivenciando a mortalidade materna na família e vivenciando a mortalidade materna na instituição de saúde. As visitas domiciliares confirmaram que existem fatores coadjuvantes que influenciaram na ocorrência das mortes maternas.La mortalidad materna es uno de los indicadores del desarrollo en salud y social de un país. Es una tragedia para la familia, pues la muerte de la madre priva al niño del amamantamiento y del contacto materno, y por el hecho de que cabe a la mujer mantener la unidad de la familia. Este estudio tuvo como objetivo comprender el significado de la muerte atribuido por familiares de las mujeres fallecidas por causas maternas. La población estuvo constituida por diez familiares de siete mujeres que murieron durante el ciclo grávido-puerperal en el municipio de Ribeirão Preto. Se efectuaron visitas domiciliarias y la recolección de datos fue realizada por medio de entrevista al familiar de la mujer. Para el análisis de los datos, se utilizó el análisis temático, desprendiéndose tres categorías temáticas: significado de la muerte materna, vivenciando la mortalidad materna en la familia y vivenciando la mortalidad

    This paper reports on an exploratory study that investigates the relationship between participants' learning style preferences and their perceptions of a professional workshop on collaboration and technology to support collaboration. The Learning Preference Scale-Students (LPSS) (Owens & Barnes......, 1992) was administered to identify participants' learning style preferences as cooperative, competitive and/or individualized. Using cluster analysis two groups, or categories, of learning style preferences among the participants emerged. Group 1 showed a strong preference for the cooperative learning...... style, and Group 2 showed a strong preference for competitive and cooperative learning styles. Group 1 rated the workshop more positively than Group 2. However, Group 2 reported a larger increase in self-efficacy compared to those in Group 1 (18.9% vs. 6.0%). Both groups provided different suggestions...

  1. Alcohol demand and risk preference.

    Dave, Dhaval; Saffer, Henry

    2008-12-01

    Both economists and psychologists have studied the concept of risk preference. Economists categorize individuals as more or less risk-tolerant based on the marginal utility of income. Psychologists categorize individuals' propensity towards risk based on harm avoidance, novelty seeking and reward dependence traits. The two concepts of risk are related, although the instruments used for empirical measurement are quite different. Psychologists have found risk preference to be an important determinant of alcohol consumption; however economists have not included risk preference in studies of alcohol demand. This is the first study to examine the effect of risk preference on alcohol consumption in the context of a demand function. The specifications employ multiple waves from the Panel Study of Income Dynamics (PSID) and the Health and Retirement Study (HRS), which permit the estimation of age-specific models based on nationally representative samples. Both of these data sets include a unique and consistent survey instrument designed to directly measure risk preference in accordance with the economist's definition. This study estimates the direct impact of risk preference on alcohol demand and also explores how risk preference affects the price elasticity of demand. The empirical results indicate that risk preference has a significant negative effect on alcohol consumption, with the prevalence and consumption among risk-tolerant individuals being 6-8% higher. Furthermore, the tax elasticity is similar across both risk-averse and risk-tolerant individuals. This suggests that tax policies are as equally effective in deterring alcohol consumption among those who have a higher versus a lower propensity for alcohol use.

Os relacionamentos familiares oscilam, contudo, entre turbulência e distanciamento afetivo. As relações de afeto mantidas com pais, cônjuges e namorados são marcadas por divergências e insatisfações. A baixa densidade da rede de amizades e o empobrecimento da vida social resultam em isolamento e dificuldades de dar início e/ou manter relacionamentos afetivos duradouros.

  9. Human preference for individual colors

    Palmer, Stephen E.; Schloss, Karen B.

    2010-02-01

    Color preference is an important aspect of human behavior, but little is known about why people like some colors more than others. Recent results from the Berkeley Color Project (BCP) provide detailed measurements of preferences among 32 chromatic colors as well as other relevant aspects of color perception. We describe the fit of several color preference models, including ones based on cone outputs, color-emotion associations, and Palmer and Schloss's ecological valence theory. The ecological valence theory postulates that color serves an adaptive "steering' function, analogous to taste preferences, biasing organisms to approach advantageous objects and avoid disadvantageous ones. It predicts that people will tend to like colors to the extent that they like the objects that are characteristically that color, averaged over all such objects. The ecological valence theory predicts 80% of the variance in average color preference ratings from the Weighted Affective Valence Estimates (WAVEs) of correspondingly colored objects, much more variance than any of the other models. We also describe how hue preferences for single colors differ as a function of gender, expertise, culture, social institutions, and perceptual experience.

    This special section is dedicated to the Strongly Correlated Electron Systems Conference (SCES) 2011, which was held from 29 August-3 September 2011, in Cambridge, UK. SCES'2011 is dedicated to 100 years of superconductivity and covers a range of topics in the area of strongly correlated systems. The correlated electronic and magnetic materials featured include f-electron based heavy fermion intermetallics and d-electron based transition metal compounds. The selected papers derived from invited presentations seek to deepen our understanding of the rich physical phenomena that arise from correlation effects. The focus is on quantum phase transitions, non-Fermi liquid phenomena, quantum magnetism, unconventional superconductivity and metal-insulator transitions. Both experimental and theoretical work is presented. Based on fundamental advances in the understanding of electronic materials, much of 20th century materials physics was driven by miniaturisation and integration in the electronics industry to the current generation of nanometre scale devices. The achievements of this industry have brought unprecedented advances to society and well-being, and no doubt there is much further to go—note that this progress is founded on investments and studies in the fundamentals of condensed matter physics from more than 50 years ago. Nevertheless, the defining challenges for the 21st century will lie in the discovery in science, and deployment through engineering, of technologies that can deliver the scale needed to have an impact on the sustainability agenda. Thus the big developments in nanotechnology may lie not in the pursuit of yet smaller transistors, but in the design of new structures that can revolutionise the performance of solar cells, batteries, fuel cells, light-weight structural materials, refrigeration, water purification, etc. The science presented in the papers of this special section also highlights the underlying interest in energy-dense materials, which

Este artigo analisa as estratégias desses produtores em relação à divisão de herança e à sucessão, e as formas que utilizam para aquisição de novas áreas. O levantamento das características das famílias e da propriedade foi realizado por meio de um questionário aplicado junto a 89 produtores familiares de três municípios da mesorregião de São José do Rio Preto (SP. Posteriormente foi entrevistado um terço dos produtores de cada município que havia respondido ao questionário. A análise das estratégias fundiárias mostrou uma grande diversidade na forma de partilhar a herança e de conduzir a sucessão, sendo que ambos os processos são apoiados, basicamente, em regras tradicionais, embora mantenham uma fachada de adequação às normas legais. Quanto às estratégias de aquisição de mais terras, observou-se que os produtores são capazes de organizar complexas formas de capitalização, centradas em maiores esforços no trabalho e na contenção de gastos, além da utilização de políticas públicas favoráveis e de práticas costumeiras. Os arranjos intra-familiares e as formas de cooperação ligadas ao parentesco mais amplo também se mostraram importantes para a ampliação da propriedade.The maintenance and/or expansion of land form the central axle along which family farming organize their livelihood and work..

Falta de crédito é detectada pelo fato dos agentes estarem restritos por sua riqueza em suas escolhas. Utilizando dados da Pesquisa Nacional por Amostra de Domicílios, observou-se, para diferentes tipos de família, forte relação entre riqueza e decisões intra-familiares. Os resultados sugerem que esta relação parece ser mais intensa para chefes de família e homens solteiros. No caso das crianças, filhos(as de mães solteiras são os mais afetados pela falta de crédito.This paper provides empirical evidence on credit constraints and key intrahousehold decisions in Brazil; namely, occupational choice of heads and spouses, child labor and education. Our empirical strategy is based on the literature about wealth-constrained choices, in which credit constraints determine a relationship between initial wealth and household decisions. Using data from the National Surveys of Households (PNAD, we show a strong connection between wealth and such decisions. Our findings suggest credit constraints are relatively more binding for spouses, couples without children and single mothers. For the case of children, the girls are more affected by the lack of credit.

  15. 'Familiarity' as a key factor influencing rural family carers' experience of the nursing home placement of an older relative: a qualitative study.

    Science.gov (United States)

    Ryan, Assumpta; McKenna, Hugh

    2013-07-03

    Admission to a nursing home is generally regarded as a stressful time for older people and their carers. Although the choice of home is significant in facilitating a more positive transition, few studies have explored this issue in detail, particularly in the context of rural communities. With a worldwide ageing population and an increasing demand for long-term care facilities, it is important to highlight the factors that can improve the experience of entry to long-term care and the role of nursing home staff in facilitating a more positive transition for older people and their families. The overall aim of this qualitative study was to explore rural family carers' experience of the nursing home placement of an older relative. Semi structured interviews were conducted with 29 relatives of nursing home residents. Participants were selected from a large health and social care trust in the United Kingdom. Data were analysed using grounded theory principles and procedures and NVivo software. Rural family carers had a strong sense of familiarity with the nursing homes in their area and this appeared to permeate all aspects of their experience. Carers who reported a high degree of familiarity appeared to experience a more positive transition than others. This familiarity was influenced by the high degree of social capital that was present in the rural community where the study was conducted. This familiarity, in turn, influenced the choice of nursing home and the responses of family carers. The theory that emerged suggests that familiarity was the key factor influencing rural family carers' experience of the nursing home placement of an older relative. The population of the world is ageing and nursing homes are increasingly providing care to older people with multiple and complex needs. This study makes an important contribution to the ways in which the move to long term care can be managed more effectively by increasing awareness of the importance of familiarity

    We show that the fermion mass spectrum may naturally be understood in terms of flavour democratic fixed points in supersymmetric theories which have a large domain of attraction in the presence of "strong unification". Our approach provides an alternative to the approximate Yukawa texture zeroes of the Froggatt-Nielsen mechanism. We discuss a particular model based on a broken gauged $SU(3)_L\\times SU(3)_R$ family symmetry which illustrates our approach.

    Full Text Available This paper considers an innovative approach to measuring public spending preferences using an interactive budgeting questionnaire. After being presented with the President’s requested budget for the upcoming fiscal year, survey respondents were asked to adjust spending levels in line with their personal preferences, subject to budgetary trade-offs. An analysis of survey results reveals that responses sharply contrast with those recovered by traditional survey measures. The results are then used to examine the relationship between fiscal preferences and self-reported ideology, and to explore the structure of budgetary preferences. It is found that preferences scale to two substantive dimensions: the first measures the trade-off between security and non-security spending and strongly correlates with self-reported ideology; and the second reveals a crosscutting cleavage that has attracted little, if any, attention in previous research. Specifically, it measures each respondent’s relative preference for rival and non-rival government goods and services.

    It has become difficult to find a matching perfume. An overwhelming number of 300 new perfumes launch each year, and marketing campaigns target pre-defined groups based on gender, age or income rather than on individual preferences. Recent evidence for a genetic basis of perfume preferences, however, could be the starting point for a novel population genetic approach to better match perfumes with people's preferences. With a total of 116 participants genotyped for alleles of three loci of the major histocompatibility complex (MHC), the aim of this study was to test whether common MHC alleles could be used as genetic markers to segment a given population into preference types. Significant deviations from random expectations for a set of 10 common perfume ingredients indicate how such segmentation could be achieved. In addition, preference patterns of participants confronted with images that contained a sexual communication context significantly differed in their ratings for some of the scents compared with participants confronted with images of perfume bottles. This strongly supports the assumption that genetically correlated perfume preferences evolved in the context of sexual communication. The results are discussed in the light of perfume customization. © 2011 The Authors. ICS © 2011 Society of Cosmetic Scientists and the Société Française de Cosmétologie.

    After testing the psychometric properties of a new questionnaire that measures patient preferences for patient-physician communication (KOPRA questionnaire), the communication preferences of cancer patients were described. In order to do this, the preferences were differentiated according to sociodemographic subgroups and a comparison was made to the preferences of patients with chronic back pain and chronic ischaemic heart disease. N=1,635 patients from 31 medical oncology practices were surveyed. For the KOPRA questionnaire, reliability, unidimensionality, and fit to the Rasch model were tested. Hierarchical models were used to conduct subgroup analyses and comparisons with other diseases. The psychometric properties of the KOPRA are satisfactory to good. For patients, the 4 communication domains (patient participation and patient orientation, effective and open communication, emotionally supportive communication, communication about personal circumstances) measured by the KOPRA questionnaire are equally important. Women generally have higher expectations of the physician's communicative behaviour. Affective communication is considerably more important for cancer patients than for back pain or cardiac patients. The KOPRA questionnaire is well suited for examining the communication preferences of cancer patients. In general, physician behaviour associated with high scores in all 4 KOPRA dimensions is optimal. Especially in cases where the 4 communication aspects conflict with each other, the physician's communication style should be individualised. © Georg Thieme Verlag KG Stuttgart · New York.

    The current study examines value preferences of social workers in Israel. Using a theoretical framework of person-environment fit paradigm and theory of values, the study compared social workers (N = 641, mean age = 37.7 years, 91 percent female) with a representative sample of Israeli Jews (N = 1,600, mean age = 44.2, 52 percent female). Questionnaires included personal value preferences and sociodemographic variables (gender, age, education, religiosity, and immigrant status). Multivariate analysis of covariance showed that value preferences of social workers differed significantly from those of the general population. Analyses of covariance showed that social workers reported a higher preference for self-transcendence and a lower preference for conservation and self-enhancement values. Results have significance for the selection, training, and supervision of social workers. They suggest that it is important to assess to what extent selection processes for social workers are primarily recruiting social workers with shared values, thus creating an overly homogenous population of social workers. An understanding of personal value motivations can help social workers in their own process of self-development and growth, and to understand how the profession can fulfill their basic motivations. © 2018 National Association of Social Workers.

    Full Text Available A análise da governança corporativa, incluindo-se a transparência da administração, tem se tornado um fator chave para conhecer as grandes empresas. Ao mesmo tempo, vem sendo apontada como um indicador de confiança dos investidores nas decisões tomadas pela administração das empresas listadas em bolsas de valores. Uma das formas de avaliar as estruturas e práticas de governança corporativa é verificar a sensibilidade do turnover de executivos ao desempenho da firma (VOLPIN, 2002. Neste artigo, objetiva-se verificar a existência de diferenças significativas de desempenho, valor e estruturas de governança corporativa entre empresas familiares e não-familiares; e, ainda, a existência de associações entre performance e turnover de executivos, tendo em vista a atuação da governança corporativa. A análise é conduzida tomando como referência um conjunto de 176 empresas industriais listadas na Bovespa, segmentadas por tipo (familiar ou não-familiar, entre 1997 e 2001. A contribuição do estudo se dá pelas peculiaridades que envolvem as empresas familiares, que não têm sido consideradas em pesquisas brasileiras, e pelo oferecimento de elementos para refletir teoricamente o desempenho das empresas familiares e suas estruturas de governança. Os resultados alcançados revelam a existência de diferenças significativas de desempenho, valor e estruturas de governança corporativa entre empresas familiares e não-familiares. É possível verificar ainda que, nas empresas familiares, quanto maior a rentabilidade, menores são os níveis de turnover.

    Full Text Available Three experiments are reported showing that the perception and the assessment of veridicality of familiar faces are highly adaptive to new visual information. Subjects were asked to discriminate between real photographs and altered versions of celebrities. Exposing participants to extremely deviated versions changed the usually stable representations of the famous faces within a very short time. In Experiment 1, exposure to an extreme face version resulted in identity decisions shifted towards the exposed one. Experiment 2 revealed that the effects are not short lasting. In Experiment 3, we showed that the effect also generalizes to different pictures of the same famous person. Together the experiments seem to indicate that the brain permanently adapts to new perceptual information and integrates new data within already elaborated representations in a fast way.

    The purpose of this study was to determine whether self-reported computer familiarity is related to performance on computerized neurocognitive testing. Participants were 130 healthy adults who self-reported whether their computer use was "some" (n = 65) or "frequent" (n = 65). The two groups were individually matched on age, education, sex, and race. All completed the CNS Vital Signs (Gualtieri & Johnson, 2006b) computerized neurocognitive battery. There were significant differences on 6 of the 23 scores, including scores derived from the Symbol-Digit Coding Test, Stroop Test, and the Shifting Attention Test. The two groups were also significantly different on the Psychomotor Speed (Cohen's d = 0.37), Reaction Time (d = 0.68), Complex Attention (d = 0.40), and Cognitive Flexibility (d = 0.64) domain scores. People with "frequent" computer use performed better than people with "some" computer use on some tests requiring rapid visual scanning and keyboard work.

    The fornix is the main tract between the medial temporal lobe (MTL) and medial diencephalon, both of which are critical for episodic memory. The precise involvement of the fornix in memory, however, has been difficult to ascertain since damage to this tract in human amnesics is invariably accompanied by atrophy to surrounding structures. We used diffusion-weighted imaging to investigate whether individual differences in fornix white matter microstructure in neurologically healthy participants were related to differences in memory as assessed by two recognition tasks. Higher microstructural integrity in the fornix tail was found to be associated with significantly better recollection memory. In contrast, there was no significant correlation between fornix microstructure and familiarity memory or performance on two non-mnemonic tasks. Our findings support the idea that there are distinct MTL-diencephalon pathways that subserve differing memory processes.

    2002-01-01

    When a high-power laser focuses into a gas of atoms, the electromagnetic field becomes of the same magnitude as the Coulomb field which binds a 1s electron in a hydrogen atom. 3 highly non-linear phenomena can happen: 1) ATI (above threshold ionization): electrons initially in the ground state absorb a large number of photons, many more than the minimum number required for ionization; 2) multiple ionization: many electrons can be emitted one at a time, in a sequential process, or simultaneously in a mechanism called direct or non-sequential; and 3) high order harmonic generation (HHG): efficient photon emission in the extreme ultraviolet range, in the form of high-order harmonics of the fundamental laser field can occur. The theoretical problem consists in solving the time dependent Schroedinger equation (TDSE) that describes the interaction of a many-electron atom with a laser field. A number of methods have been proposed to solve this problem in the case of a hydrogen atom or a single-active electron atom in a strong laser field. A large effort is presently being devoted to go beyond the single-active approximation. The understanding of the physics of the interaction between atoms and strong laser fields has been provided by a very simple model called ''simple man's theory''. A unified view of HHG, ATI, and non-sequential ionization, originating from the simple man's model and the strong field approximation, expressed in terms of electrons trajectories or quantum paths is slowly emerging.

  3. Episodic and Semantic Memory Contribute to Familiar and Novel Episodic Future Thinking.

    Increasing evidence indicates that episodic future thinking (EFT) relies on both episodic and semantic memory; however, event familiarity may importantly affect the extent to which episodic and semantic memory contribute to EFT. To test this possibility, two behavioral experiments were conducted. In Experiment 1, we directly compared the proportion of episodic and semantic memory used in an EFT task. The results indicated that more episodic memory was used when imagining familiar future events compared with novel future events. Conversely, significantly more semantic memory was used when imagining novel events compared with familiar events. Experiment 2 aimed to verify the results of Experiment 1. In Experiment 2, we found that familiarity moderated the effect of priming the episodic memory system on EFT; particularly, it increased the time required to construct a standard familiar episodic future event, but did not significantly affect novel episodic event reaction time. Collectively, these findings support the hypothesis that event familiarity importantly moderates episodic and semantic memory's contribution to EFT.

    2015-01-01

    The scalar strong interaction hadron theory, SSI, is a first principles' and nonlocal theory at quantum mechanical level that provides an alternative to low energy QCD and Higgs related part of the standard model. The quark-quark interaction is scalar rather than color-vectorial. A set of equations of motion for mesons and another set for baryons have been constructed. This book provides an account of the present state of a theory supposedly still at its early stage of development. This work will facilitate researchers interested in entering into this field and serve as a basis for possible future development of this theory.

    2015-12-01

    Models of mantle convection on Earth produce styles of convection that are not observed on Earth.Moreover non-Earth-like modes, such as two-sided downwellings, are the de facto mode of convection in such models.To recreate Earth style subduction, i.e. one-sided asymmetric recycling of the lithosphere, proper treatment of the plates and plate interface are required. Previous work has identified several model features that promote subduction. A free surface or pseudo-free surface and a layer of material with a relatively low strength material (weak crust) allow downgoing plates to bend and slide past overriding without creating undue stress at the plate interface. (Crameri, et al. 2012, GRL)A low viscosity mantle wedge, possibly a result of slab dehydration, decouples the plates in the system. (Gerya et al. 2007, Geo)Plates must be composed of material which, in the case of the overriding plate, are is strong enough to resist bending stresses imposed by the subducting plate and yet, as in the case of the subducting plate, be weak enough to bend and subduct when pulled by the already subducted slab. (Petersen et al. 2015, PEPI) Though strong surface plates are required for subduction such plates may present a problem when they encounter the lower mantle.As the subducting slab approaches the higher viscosity, lower mantle stresses are imposed on the tip.Strong slabs transmit this stress to the surface.There the stress field at the plate interface is modified and potentially modifies the style of convection. In addition to modifying the stress at the plate interface, the strength of the slab affects the morphology of the slab at the base of the upper mantle. (Stegman, et al 2010, Tectonophysics)Slabs that maintain a sufficient portion of their strength after being bent require high stresses to unbend or otherwise change their shape.On the other hand slabs that are weakened though the bending process are more amenable to changes in morphology. We present the results of

  9. Strong-Weak CP Hierarchy from Non-Renormalization Theorems

    2002-01-28

    We point out that the hierarchy between the measured values of the CKM phase and the strong CP phase has a natural origin in supersymmetry with spontaneous CP violation and low energy supersymmetry breaking. The underlying reason is simple and elegant: in supersymmetry the strong CP phase is protected by an exact non-renormalization theorem while the CKM phase is not. We present explicit examples of models which exploit this fact and discuss corrections to the non-renormalization theorem in the presence of supersymmetry breaking. This framework for solving the strong CP problem has generic predictions for the superpartner spectrum, for CP and flavor violation, and predicts a preferred range of values for electric dipole moments.

  10. Visual search and eye movements in novel and familiar contexts

    2006-02-01

    Adapting to the visual characteristics of a specific environment may facilitate detecting novel stimuli within that environment. We monitored eye movements while subjects searched for a color target on familiar or unfamiliar color backgrounds, in order to test for these performance changes and to explore whether they reflect changes in salience from adaptation vs. changes in search strategies or perceptual learning. The target was an ellipse of variable color presented at a random location on a dense background of ellipses. In one condition, the colors of the background varied along either the LvsM or SvsLM cardinal axes. Observers adapted by viewing a rapid succession of backgrounds drawn from one color axis, and then searched for a target on a background from the same or different color axis. Searches were monitored with a Cambridge Research Systems Video Eyetracker. Targets were located more quickly on the background axis that observers were pre-exposed to, confirming that this exposure can improve search efficiency for stimuli that differ from the background. However, eye movement patterns (e.g. fixation durations and saccade magnitudes) did not clearly differ across the two backgrounds, suggesting that how the novel and familiar backgrounds were sampled remained similar. In a second condition, we compared search on a nonselective color background drawn from a circle of hues at fixed contrast. Prior exposure to this background did not facilitate search compared to an achromatic adapting field, suggesting that subjects were not simply learning the specific colors defining the background distributions. Instead, results for both conditions are consistent with a selective adaptation effect that enhances the salience of novel stimuli by partially discounting the background.

  15. Social familiarity modulates group living and foraging behaviour of juvenile predatory mites

    Strodl, Markus A.; Schausberger, Peter

    2012-04-01

    Environmental stressors during early life may have persistent consequences for phenotypic development and fitness. In group-living species, an important stressor during juvenile development is the presence and familiarity status of conspecific individuals. To alleviate intraspecific conflicts during juvenile development, many animals evolved the ability to discriminate familiar and unfamiliar individuals based on prior association and use this ability to preferentially associate with familiar individuals. Assuming that familiar neighbours require less attention than unfamiliar ones, as predicted by limited attention theory, assorting with familiar individuals should increase the efficiency in other tasks. We assessed the influence of social familiarity on within-group association behaviour, development and foraging of juvenile life stages of the group-living, plant-inhabiting predatory mite Phytoseiulus persimilis. The observed groups consisted either of mixed-age familiar and unfamiliar juvenile mites or of age-synchronized familiar or unfamiliar juvenile mites or of pairs of familiar or unfamiliar larvae. Overall, familiar mites preferentially grouped together and foraged more efficiently, i.e. needed less prey at similar developmental speed and body size at maturity, than unfamiliar mites. Preferential association of familiar mites was also apparent in the inter-exuviae distances. Social familiarity was established by imprinting in the larval stage, was not cancelled or overridden by later conspecific contacts and persisted into adulthood. Life stage had an effect on grouping with larvae being closer together than nymphal stages. Ultimately, optimized foraging during the developmental phase may relax within-group competition, enhance current and future food supply needed for optimal development and optimize patch exploitation and leaving under limited food.

    Diagnosing epilepsy is a lengthy and burdensome process for patients and their family. Although the need for a more patient-centered approach in clinical practice is widely acknowledged, empirical evidence regarding patient preferences for diagnostic modalities in epilepsy is missing. The objectives of this study were 1) to identify to what extent important attributes of diagnostic procedures in epilepsy affect preferences for a procedure, 2) to determine the relative importance of these attributes, and 3) to calculate overall utility scores for routine electroencephalography (EEG) and magnetoencephalography (MEG) recordings. A discrete choice experiment was performed to determine patients' preferences, which involved presentation of pairwise choice tasks regarding hypothetical scenarios. Scenarios varied along six attributes: "way of measuring brain activity", "duration", "freedom of movement", "travel time", "type of additional examination", and "chance of additional examination". Choice tasks were constructed using a statistically efficient design, and the questionnaire contained 15 unique unlabeled choice tasks. Mixed multinomial logistic regression was used to estimate patients' preferences. A total of 289 questionnaires were included in the analysis. McFadden's pseudo R(2) showed a model fit of 0.28, and all attributes were statistically significant. Heterogeneity in preferences was present for all attributes. "Freedom of movement" and "Chance of additional examination" were perceived as the most important attributes. Overall utility scores did not substantially differ between routine EEG and MEG. This study suggests that the identified attributes are important in determining patients' preference for epilepsy diagnostics. It can be concluded that MEG is not necessarily more patient-friendly than a routine EEG in primary diagnostics and, regarding additional diagnostics, patients have a strong preference for long-term 24-h EEG over EEG after sleep deprivation

    Strongly correlated electrons is an exciting and diverse field in condensed matter physics. This special issue aims to capture some of that excitement and recent developments in the field. Given that this issue was inspired by the 2010 International Conference on Strongly Correlated Electron Systems (SCES 2010), we briefly give some history in order to place this issue in context. The 2010 International Conference on Strongly Correlated Electron Systems was held in Santa Fe, New Mexico, a reunion of sorts from the 1989 International Conference on the Physics of Highly Correlated Electron Systems that also convened in Santa Fe. SCES 2010—co-chaired by John Sarrao and Joe Thompson—followed the tradition of earlier conferences, in this century, hosted by Buzios (2008), Houston (2007), Vienna (2005), Karlsruhe (2004), Krakow (2002) and Ann Arbor (2001). Every three years since 1997, SCES has joined the International Conference on Magnetism (ICM), held in Recife (2000), Rome (2003), Kyoto (2006) and Karlsruhe (2009). Like its predecessors, SCES 2010 topics included strongly correlated f- and d-electron systems, heavy-fermion behaviors, quantum-phase transitions, non-Fermi liquid phenomena, unconventional superconductivity, and emergent states that arise from electronic correlations. Recent developments from studies of quantum magnetism and cold atoms complemented the traditional subjects and were included in SCES 2010. 2010 celebrated the 400th anniversary of Santa Fe as well as the birth of astronomy. So what's the connection to SCES? The Dutch invention of the first practical telescope and its use by Galileo in 1610 and subsequent years overturned dogma that the sun revolved about the earth. This revolutionary, and at the time heretical, conclusion required innovative combinations of new instrumentation, observation and mathematics. These same combinations are just as important 400 years later and are the foundation of scientific discoveries that were discussed

    The goal of this study is to evaluate the difference of the preferred hues of familiar objects between the color deficient observer and the normal observer. Thirteen test color images were chosen covering fruit colors, natural scene and human faces. It contained red, yellow, green, blue, purple and skin color. Two color deficient observer (deuteranomal) and two normal observers were participated in this experiment. They controlled the YCC hue of the objects in the images to obtain the most preferred and the most natural image. The selected images were analyzed using CIELAB values of each pixel. Data analysis results showed that in the case of naturalness, both groups selected the similar hues for the most of image, while, in the case of preference, the color deficient observer preferred more reddish or more greenish images. Since the deuteranomalous observer has relatively week perception for red and green region, they may prefer more reddish or greenish color. The color difference between natural hue and preferred hue of deuteranomal observer is bigger than those of normal observer.

    Full Text Available We take a new look at the question of the Arab democratic exception by looking at the preference for democracy among individuals in the Arab world in a comparative context. We use the new sixth wave of the World Value Survey, which was collected between 2012 and 2013, and which included for the first time 12 Arab countries (up from only four in wave 5 and 68 non-Arab countries. We innovate empirically by measuring the preference for democracy over strong rule in a way that, we argue, is more adapted to an understanding of the Arab world than other measures used in past studies. Our statistical analysis reveals a democratic gap in the Arab region compared to global experience, which is especially marked among the more educated individuals, and to a lesser extent among the youth and the middle class. We conclude by discussing the reasons that may explain the Arab exceptionalism, and argue that it is unlikely to be related to culture alone.

    Customer preference (CP), or green pricing, may be the financial hedge for electric supply industry integration of photovoltaics. CP is currently defined as a voluntary contribution for energy generated with renewable resources. Several utilities have examined the CP financing of renewables through experimental or implemented programs and market research. This paper first expands the concept of customer preference to include both voluntary and involuntary customer contributions. It then categorizes the features of existing and proposed CP programs. The connections between these features and market research and marketing strategies for new product development from a competitive industry are analyzed

    Background Non-medical professionals (consumers) are increasingly using the Internet to support their health information needs. However, the cognitive effort required to perform health information searches is affected by the consumer’s familiarity with health topics. Consumers may have different levels of familiarity with individual health topics. This variation in familiarity may cause misunderstandings because the information presented by search engines may not be understood correctly by the consumers. Objective As a first step toward the improvement of the health information search process, we aimed to examine the effects of health topic familiarity on health information search behaviors by identifying the common search activity patterns exhibited by groups of consumers with different levels of familiarity. Methods Each participant completed a health terminology familiarity questionnaire and health information search tasks. The responses to the familiarity questionnaire were used to grade the familiarity of participants with predefined health topics. The search task data were transcribed into a sequence of search activities using a coding scheme. A computational model was constructed from the sequence data using a Markov chain model to identify the common search patterns in each familiarity group. Results Forty participants were classified into L1 (not familiar), L2 (somewhat familiar), and L3 (familiar) groups based on their questionnaire responses. They had different levels of familiarity with four health topics. The video data obtained from all of the participants were transcribed into 4595 search activities (mean 28.7, SD 23.27 per session). The most frequent search activities and transitions in all the familiarity groups were related to evaluations of the relevancy of selected web pages in the retrieval results. However, the next most frequent transitions differed in each group and a chi-squared test confirmed this finding (Pinformation search patterns

    We can easily recognize familiar music by listening to only one or 2 of its opening bars, but the brain regions that participate in this cognitive processing remain undetermined. We used positron-emission tomography (PET) to study changes in regional cerebral blood flow (rCBF) that occur during listening to familiar music. We used a PET subtraction technique to elucidate the brain regions associated with the recognition of familiar melodies such as well-known nursery tunes. Nonmusicians performed 2 kinds of musical tasks: judging the familiarity of musical pieces (familiarity task) and detecting deliberately altered notes in the pieces (alteration-detecting task). During the familiarity task, bilateral anterior portions of bilateral temporal lobes, superior temporal regions, and parahippocampal gyri were activated. The alteration-detecting task bilaterally activated regions in the precunei, superior/inferior parietal lobules, and lateral surface of frontal lobes, which seemed to show a correlation with the analysis of music. We hypothesize that during the familiarity task, activated brain regions participate in retrieval from long-term memory and verbal and emotional processing of familiar melodies. Our results reinforced the hypothesis reported in the literature as a result of group and case studies, that temporal lobe regions participate in the recognition of familiar melodies.

    Purpose The goal of this research was to examine whether phonological familiarity exerts different effects on novel word learning for familiar vs. unfamiliar referents, and whether successful word-learning is associated with increased second-language experience. Method Eighty-one adult native English speakers with various levels of Spanish knowledge learned phonologically-familiar novel words (constructed using English sounds) or phonologically-unfamiliar novel words (constructed using non-English and non-Spanish sounds) in association with either familiar or unfamiliar referents. Retention was tested via a forced-choice recognition-task. A median-split procedure identified high-ability and low-ability word-learners in each condition, and the two groups were compared on measures of second-language experience. Results Findings suggest that the ability to accurately match newly-learned novel names to their appropriate referents is facilitated by phonological familiarity only for familiar referents but not for unfamiliar referents. Moreover, more extensive second-language learning experience characterized superior learners primarily in one word-learning condition: Where phonologically-unfamiliar novel words were paired with familiar referents. Conclusions Together, these findings indicate that phonological familiarity facilitates novel word learning only for familiar referents, and that experience with learning a second language may have a specific impact on novel vocabulary learning in adults.

    Previous research has shown that familiarity with a talker's voice can improve linguistic processing (herein, "Familiar Talker Advantage"), but this benefit is constrained by the context in which the talker's voice is familiar. The current study examined how familiarity affects intelligibility by manipulating the type of talker information available to listeners. One group of listeners learned to identify bilingual talkers' voices from English words, where they learned language-specific talker information. A second group of listeners learned the same talkers from German words, and thus only learned language-independent talker information. After voice training, both groups of listeners completed a word recognition task with English words produced by both familiar and unfamiliar talkers. Results revealed that English-trained listeners perceived more phonemes correct for familiar than unfamiliar talkers, while German-trained listeners did not show improved intelligibility for familiar talkers. The absence of a processing advantage in speech intelligibility for the German-trained listeners demonstrates limitations on the Familiar Talker Advantage, which crucially depends on the language context in which the talkers' voices were learned; knowledge of how a talker produces linguistically relevant contrasts in a particular language is necessary to increase speech intelligibility for words produced by familiar talkers. © 2011 Acoustical Society of America

  13. Selective lesion to the entorhinal cortex leads to an impairment in familiarity but not recollection.

    The present research explored the effects of selective impairment to the entorhinal cortex on the processes of familiarity and recollection. To achieve this objective, the performance of patient MR, who has a selective impairment of the left entorhinal cortex, was compared to that of age and IQ-matched controls. Four experiments tested participants' recognition memory for familiar and unfamiliar faces and words. In all experiments, participants studied lists of items and then completed an old/new recognition test in which they also made remember/know/guess judgements. A fifth experiment tested participants' priming associated with the familiarity process. MR had intact performance in both face recognition experiments as well as having intact performance in pseudoword recognition. Crucially, however, in the familiar word experiment, whilst MR performed similarly to control participants in terms of recollection, she showed a marked impairment in familiarity. Furthermore, she also demonstrated a reversed conceptual priming effect. MR's impairment is both material-specific and selective for previously encountered but not new verbal items (pseudowords). These findings provide the first clear evidence that selective impairment of the entorhinal cortex impairs the familiarity process for familiar verbal material whilst leaving recollection intact. These results suggest the entorhinal cortex does not have attributes reflective of both recollection and familiarity as previously assumed, but rather supports context-free long-term familiarity-based recognition memory.

    Differences in end-of-life (EOL) care preferences (eg, location of death, use of life-sustaining treatments, openness to hastening death, etc) based on hypothetical death scenarios and associated physical and/or cognitive losses have yet to be investigated within the palliative care literature. The purpose of this study was to explore the multidimensional EOL care preferences in relation to 3 different hypothetical death scenarios: pancreatic cancer (acute death), Alzheimer disease (gradual death), and congestive heart failure (intermittent death). General linear mixed-effects regression models estimated whether multidimensional EOL preferences differed under each of the hypothetical death scenarios; all models controlled for personal experience and familiarity with the disease, presence of an advance directive, religiosity, health-related quality of life, and relevant demographic characteristics. A national sample of healthy adults aged 50 years and older (N = 517) completed electronic surveys detailing their multidimensional preferences for EOL care for each hypothetical death scenario. The average age of the participants was 60.1 years (standard deviation = 7.6), 74.7% were female, and 66.1% had a college or postgraduate degree. Results revealed significant differences in multidimensional care preferences between hypothetical death scenarios related to preferences for location of death (ie, home vs medical facility) and preferences for life-prolonging treatment options. Significant covariates of participants' multidimensional EOL care preferences included age, sex, health-related quality of life, and religiosity. Our hypothesis that multidimensional EOL care preferences would differ based on hypothetical death scenarios was partially supported and suggests the need for disease-specific EOL care discussions.

    In this study, the suitability of butyrate as substrate for polyhydroxyalkanoate (PHA) production by microbial enrichment cultures was assessed. Two sequencing batch reactors were operated under feast-famine conditions: one fed with butyrate, and another with mixed acetate and butyrate. The obtained results were compared to previous results with acetate as sole substrate. In all three reactors Plasticicumulans acidivorans dominated the enrichment culture. The carbon uptake rate and PHA yield were significantly higher on butyrate than on acetate, resulting in a higher PHA production rate. When both substrates were available the bacteria strongly preferred the uptake of butyrate. Only after butyrate depletion acetate was taken up at a high rate. The molar substrate uptake rate remained the same, suggesting that substrate uptake is the rate-limiting step. The results show that for optimized waste-based PHA production the pre-fermentation process should be directed towards butyrate production. Copyright © 2013 Elsevier Ltd. All rights reserved.

  16. Social preferences influence the short-term exchange of social grooming among male bonobos.

    2015-03-01

    The emotional mediation hypothesis proposes a mediating role of social bonds in the exchange of services. This model predicts that the form of short-term exchange of services depends on the relationship between the individuals involved. Here, we test this prediction in the exchange of grooming among males in a wild bonobo community for which close relatedness could be excluded. As bonobo males hardly engage in food sharing or agonistic support, grooming is mainly exchanged for grooming. While overall grooming, both given and received, correlates across dyads and within sessions, the form of grooming exchange within a given session differs according to dyadic association preferences. Individuals with a higher tendency to associate, ergo more familiar individuals, exhibit larger time differences and reduced reciprocation in consecutive grooming bouts than less familiar individuals. These results support the idea that emotional components are involved in the exchange of services between unrelated individuals.

  17. Physics of Strongly Coupled Plasma

    Kraeft, Wolf-Dietrich [Universitat Rostock (Germany)

    2007-07-15

    Strongly coupled plasmas (or non-ideal plasmas) are multi-component charged many-particle systems, in which the mean value of the potential energy of the system is of the same order as or even higher than the mean value of the kinetic energy. The constituents are electrons, ions, atoms and molecules. Dusty (or complex) plasmas contain still mesoscopic (multiply charged) particles. In such systems, the effects of strong coupling (non-ideality) lead to considerable deviations of physical properties from the corresponding properties of ideal plasmas, i.e., of plasmas in which the mean kinetic energy is essentially larger than the mean potential energy. For instance, bound state energies become density dependent and vanish at higher densities (Mott effect) due to the interaction of the pair with the surrounding particles. Non-ideal plasmas are of interest both for general scientific reasons (including, for example, astrophysical questions), and for technical applications such as inertially confined fusion. In spite of great efforts both experimentally and theoretically, satisfactory information on the physical properties of strongly coupled plasmas is not at hand for any temperature and density. For example, the theoretical description of non-ideal plasmas is possible only at low densities/high temperatures and at extremely high densities (high degeneracy). For intermediate degeneracy, however, numerical experiments have to fill the gap. Experiments are difficult in the region of 'warm dense matter'. The monograph tries to present the state of the art concerning both theoretical and experimental attempts. It mainly includes results of the work performed in famous Russian laboratories in recent decades. After outlining basic concepts (chapter 1), the generation of plasmas is considered (chapter 2, chapter 3). Questions of partial (chapter 4) and full ionization (chapter 5) are discussed including Mott transition and Wigner crystallization. Electrical and

    Actually, the coffee is one of the most important exportation crops of the country. The utilization of obsolete or unsuitable processes, specifically related to the coffee drying, it can to damage the final quality of the product, besides to result in a low profitability of the coffee growing. In this work a mechanical drier (flex) was built, for the familiar coffee growing, being subsequently evaluated, to the drying of peeled cherry coffee, by the realization of two tests: one with heating of the air using vegetable coal and other combining the use of solar heater with vegetable coal. Basing on the results, it was possible to conclude that the drying of coffee in the mechanical drier Flex can be carried out using vegetable coal as fuel as well as associating the use of the vegetable coal with the solar collector, to save energy.

    The structures and motions of quasi-2-dimensional strongly coupled dust Coulomb clusters with particle number N from few to hundreds in a cylindrical rf plasma trap are studied and compared with the results from the molecular dynamic simulation using more ideal models. Shell structures with periodic packing in different shells and intershell rotational motion dominated excitations are observed at small N. As N increases, the boundary has less effect, the system recovers to the triangular lattice with isotropic vortex type cooperative excitations similar to an infinite N system except the outer shell region. The above generic behaviors are mainly determined by the system symmetry and agree with the simulation results. The detailed interaction form causes minor effect such as the fine structure of packing

    In this work we, using Mellin’s transform combined with the Gaussian large-scale boundary condition, calculate probability densities (PDFs) of velocity increments P(δu,r), velocity derivatives P(u,r) and the PDF of the fluctuating dissipation scales Q(η,Re), where Re is the large-scale Reynolds number. The resulting expressions strongly deviate from the Log-normal PDF P(δu,r) often quoted in the literature. It is shown that the probability density of the small-scale velocity fluctuations includes information about the large (integral) scale dynamics which is responsible for the deviation of P(δu,r) from P(δu,r). An expression for the function D(h) of the multifractal theory, free from spurious logarithms recently discussed in [U. Frisch, M. Martins Afonso, A. Mazzino, V. Yakhot, J. Fluid Mech. 542 (2005) 97] is also obtained.

    Subjective preferences affect many processes, including motivation, along with individual differences. Although incentive motivations are proposed to increase our limited visual working memory (VWM) capacity, much less is known about the effects of subjective preferences on VWM-related brain systems, such as the prefrontal and parietal cortices. Here, we investigate the differences in VWM capacities and brain activities during presentation of preferred and non-preferred colors. To this end, we used time-frequency (TF) analyses of electroencephalograph (EEG) data recorded during a delayed-response task. Behavioral results showed that the individual VWM capacities of preferred colors were significantly higher than those of non-preferred colors. The EEG results showed that the frontal theta and beta amplitudes for maintenance of preferred colors were higher than those of non-preferred colors. Interestingly, the frontal beta amplitudes were consistent with recent EEG recordings of the effects of reward on VWM systems, in that they were strongly and individually correlated with increasing VWM capacities from non-preferred to preferred colors. These results suggest that subjective preferences affect VWM systems in a similar manner to reward-incentive motivations.

    This study investigated preferences for behavioural, analytic and gestalt psychotherapy among a sample of 40 SES class III and IV adult females and 67 college freshmen who had never been actual therapy patients. A scaled survey assessed general preference, preference given an imagined long-standing depressive disorder, preference given an imagined specific phobia, and preference for the therapist-patient relationship. Three audio tapes were designed, each describing one of the modalities. High inter-rater reliability and agreement were determined by three independent judges. Results showed that young females had a general preference for gestalt therapy. Young and old females, but not young males, significantly preferred behavioural therapy for a specific phobia. Under forced-choice conditions the group as a whole significantly preferred gestalt therapy. No differences were found for the relationship or preference given a depressive disorder. Preference was hypothesized as a cognitive structure with potential use in therapist-client matching.

    Increasing evidence suggests that action digital game training can improve a variety of perceptual and cognitive abilities, including those that decline most with age. Unfortunately, previous work has found that older adults dislike these games and adherence may be poor for action game-based interventions. The focus of the current study was to better understand the types of games older adults are willing to play and explore predictors of game preference (e.g., gender, age, technology experience, personality). With this information action games might be modified or developed to maximize adherence and cognitive benefit. Older adults were administered a modified version of an existing game questionnaire and a custom game preference survey. Clear preferences were observed that were similar between participants with and without previous digital game experience (with puzzle and intellectually stimulating games being most interesting to older adults in our sample, and massively multiplayer online games and first-person shooters being least interesting). Personality, demographic, and technology experience variables were also collected. Interesting trends suggested the possibility that several demographic and personality variables might be predictive of game preference. Results have implications for future directions of research, designing games that would appeal to older adult audiences, and for how to design custom games to maximize intervention adherence based on individual difference characteristics.

  8. LATER RETIREMENT? PATTERNS, PREFERENCES, POLICIES

    Full Text Available Pension systems are a major part of the political economy of current societies – much beyond providing old-age income security. The well-known demographics of population aging as well as globalization today challenge their financial viability. Later retirement seems to be a good way to meet these challenges. However, it is not only unpopular but also inequitable in terms of differential longevity. The paper first discusses these problems, with a particular focus on the social stratification of mortality. It then analyzes the preferences towards retirement age at several levels:  in terms of attitudes towards public spending on pensions or towards the state’s responsibility in this matter, of support for pension policy alternatives, and of preferred individual age of retirement. Results show that large majorities across all age groups are in favour of more government spending on pensions. There is a substantial amount of ‘involuntary retirement’, meaning that people would have preferred to work longer than they actually did, as well as a somewhat lower amount of ‘involuntary work’, but the preferred ages are everywhere below 65, and in some countries still below 60. Finally, the paper examines the policies of raising the retirement age adopted during the last two decades. What has especially been lacking in these policies is a consideration of socially differentiated longevity.

    Numbers permeate modern political communication. While current scholarship on framing effects has focused on the persuasive effects of words and arguments, this article shows that framing of numbers can also substantially affect policy preferences. Such effects are caused by ratio bias, which...

    Risk taking is central to human activity. Consequently, it lies at the focal point of behavioral sciences such as neuroscience, economics, and finance. Many influential models from these sciences assume that financial risk preferences form a stable trait. Is this assumption justified and, if not, what causes the appetite for risk to fluctuate? We have previously found that traders experience a sustained increase in the stress hormone cortisol when the amount of uncertainty, in the form of market volatility, increases. Here we ask whether these elevated cortisol levels shift risk preferences. Using a double-blind, placebo-controlled, cross-over protocol we raised cortisol levels in volunteers over 8 d to the same extent previously observed in traders. We then tested for the utility and probability weighting functions underlying their risk taking and found that participants became more risk-averse. We also observed that the weighting of probabilities became more distorted among men relative to women. These results suggest that risk preferences are highly dynamic. Specifically, the stress response calibrates risk taking to our circumstances, reducing it in times of prolonged uncertainty, such as a financial crisis. Physiology-induced shifts in risk preferences may thus be an underappreciated cause of market instability.

  20. Relationships between food neophobia and food intake and preferences

    Food neophobia (FN) has been shown to be a strong influence on food preferences using primarily small data sets. This has limited the explanatory power of FN and the extent to which it can be related to other factors that influence food choice. To address these limitations, we collected Food...... Neophobia Scale data from 1167 adults from New Zealand over a 45-month period. Participants also completed a 112-item food preference questionnaire and a self-report 24 h, a 145 item food intake recall survey, and the Food Choice Questionnaire (FCQ). As a way of providing a structure to the food intake...... and preference data, in each case the food items were condensed into patterns described in terms of the foods/beverages with highest factor loadings. We then determined the impact of season and participant age, gender, education and income on these factors, as well as the interaction of these variables with FN...
