    Videogames challenge our notions of identity, creativity, and moral value, and provide a powerful new avenue for teaching and learning. This book is a rich and provocative guide to the role of interactive media in cultural learning. It searches for specific ways to interpret videogames in the context of human experience and in the field of…

  2. Definition of Videogames

    Full Text Available Can videogames be defined? The new field of games studies has generated three somewhat competing models of videogaming that characterize games as new forms of gaming, narratives, and interactive fictions. When treated as necessary and sufficient condition definitions, however, each of the three approaches fails to pick out all and only videogames. In this paper I argue that looking more closely at the formal qualities of definition helps to set out the range of definitional options open to the games theorist. A disjunctive definition of videogaming seems the most appropriate of these definitional options. The disjunctive definition I offer here is motivated by the observation that there is more than one characteristic way of being a videogame.

  3. Videogames, consumption and education

    Full Text Available The ever-increasing success and use of videogames is a reality in our current society, being 54% of the total consumption of audiovisual or interactive entertainment in Spain in 2007. One of the aspects to be taken into consideration, with respect to the education of children, is the implication for consumption in relation to videogames. The violence portrayed in these games is one of the main topics of debate in the literature about and studies on the effects of videogames on children’s behaviour. However, it is not just a question of protecting minors against the risks of videogames use without control and care exercised by parents or educators. For many years now, despite the risks involved in their use, videogames have been used as another medium in education itself.

    Hypothesis-driven experimentation - the scientific method - can be subverted by fraud, irreproducibility, and lack of rigorous predictive tests. A robust solution to these problems may be the 'massive open laboratory' model, recently embodied in the internet-scale videogame EteRNA. Deploying similar platforms throughout biology could enforce the scientific method more broadly. Copyright © 2014 Elsevier Ltd. All rights reserved.

  6. EVI and MDS/EVI are required for adult intestinal stem cell formation during postembryonic vertebrate development.

    The gene ectopic viral integration site 1 (EVI) and its variant myelodysplastic syndrome 1 (MDS)/EVI encode zinc-finger proteins that have been recognized as important oncogenes in various types of cancer. In contrast to the established role of EVI and MDS/EVI in cancer development, their potential function during vertebrate postembryonic development, especially in organ-specific adult stem cells, is unclear. Amphibian metamorphosis is strikingly similar to postembryonic development around birth in mammals, with both processes taking place when plasma thyroid hormone (T3) levels are high. Using the T3-dependent metamorphosis in Xenopus tropicalis as a model, we show here that high levels of EVI and MDS/EVI are expressed in the intestine at the climax of metamorphosis and are induced by T3. By using the transcription activator-like effector nuclease gene editing technology, we have knocked out both EVI and MDS/EVI and have shown that EVI and MDS/EVI are not essential for embryogenesis and premetamorphosis in X. tropicalis On the other hand, knocking out EVI and MDS/EVI causes severe retardation in the growth and development of the tadpoles during metamorphosis and leads to tadpole lethality at the climax of metamorphosis. Furthermore, the homozygous-knockout animals have reduced adult intestinal epithelial stem cell proliferation at the end of metamorphosis (for the few that survive through metamorphosis) or during T3-induced metamorphosis. These findings reveal a novel role of EVI and/or MDS/EVI in regulating the formation and/or proliferation of adult intestinal adult stem cells during postembryonic development in vertebrates.-Okada, M., Shi, Y.-B. EVI and MDS/EVI are required for adult intestinal stem cell formation during postembryonic vertebrate development. © FASEB.

    2004-01-01

    Since the first case of videogame (VG) epilepsy was reported in 1981, many cases of seizures triggered by VGs were reported, not only in photosensitive, but also in non-photosensitive children and adolescents with epilepsy. We provide an overview of the literature with overall conclusions and recommendations regarding VG playing. Specific preventive measures concerning the physical characteristics of images included in commercially available VGs (flash rate, choice of colors, patterns, and contrast) can lead in the future to a clear decrease of this problem. In addition to the positive effect of such measures, the collaborative studies performed in France and in the rest of Europe have stressed the importance of a safe distance to the screen of > or = 2 m, and the less provocative role of 100-Hz screens.

    Introduction Why should we define the term videogame? Because we have reasons to study videogames. What are these reasons? James Newman gives us an answer: "the size of the videogames industry; the popularity of videogames; videogames as an example of human-computer interaction." Indeed, videogames belong to of our culture. But surprisingly, it is rare to come across concise definitions of the word videogame. Then, it is necessary to work on it. I am not claiming that nobody defined properly ...

    Active regulation of protein abundance is an essential strategy to modulate cellular signaling pathways. Within the Wnt signaling cascade, regulated degradation of β-catenin by the ubiquitin-proteasome system (UPS) affects the outcome of canonical Wnt signaling. Here, we found that abundance of the Wnt cargo receptor Evi (Wls/GPR177), which is required for Wnt protein secretion, is also regulated by the UPS through endoplasmic reticulum (ER)-associated degradation (ERAD). In the absence of Wnt ligands, Evi is ubiquitinated and targeted for ERAD in a VCP-dependent manner. Ubiquitination of Evi involves the E2-conjugating enzyme UBE2J2 and the E3-ligase CGRRF1. Furthermore, we show that a triaging complex of Porcn and VCP determines whether Evi enters the secretory or the ERAD pathway. In this way, ERAD-dependent control of Evi availability impacts the scale of Wnt protein secretion by adjusting the amount of Evi to meet the requirement of Wnt protein export. As Wnt and Evi protein levels are often dysregulated in cancer, targeting regulatory ERAD components might be a useful approach for therapeutic interventions. © 2018 The Authors.

    Full Text Available The following text contains a brief journey through a short and yet intense adventure, the history of videogames. Since its beginnings in the 1950's decade to the present time, videogames have progressively changed from a hobby for ingeneering studens to the most powerfull leisure industry. In order to gain a better understanding of this phenomenon it is necessary to look over the path of its transformation from a retrospecive point of view. Such a look has necessarily to focus on those devices and games that had made a landmark in the history of videogames, taking them to their current position. Besides, it is crucial to address their implications in contemporary visual culture, along with current prejudices against them. This is a short account about a great history.

  17. Examining Enjoyment of Casual Videogames.

    Shafer, Daniel M; Carbonara, Corey P

    2015-12-01

    This study investigated the processes leading to enjoyment of casual videogames on both mobile devices and console systems. Building upon a foundation in mental models theory and the psychology of play, the study focuses on how performance and experience-based variables impact enjoyment of casual videogames played on mobile devices and console devices. The grounding assumption of this research is that playing videogames produces enjoyment that contributes to mental health in the form of a brief distraction from the stress of daily life, social connections with family and friends through casual gameplay, and, in some cases, a compelling reason to engage in physical activity. A student sample of players (n=363) played a variety of casual games on mobile (iPad(®) or iPod(®) Touch(®) [Apple, Cupertino, CA]) or console (Wii™ [Nintendo, Japan], Xbox(®) 360 Kinect(®) [Microsoft, Redmond, WA], or PS3™ Move [Sony, Tokyo, Japan]) platforms. They then answered a questionnaire assessing their evaluations of the game's interactivity level, their sense of spatial presence in the game, their perception of the game's realism, and, most importantly, their enjoyment. Path analysis demonstrated the interrelationships among these variables. The results show that spatial presence is a powerful predictor of videogame enjoyment for both console- and mobile-based casual games. Patterns of prediction for games on each platform, as demonstrated using path analysis, were similar and aligned with predictions based on mental models and the psychology of play. The psychological theory of play and the mental models perspective offer firm theoretical grounds for understanding how enjoyment is wrought in the process of playing casual games. The relationships among interactivity, spatial presence, perceived reality, and enjoyment hold for games played on handheld or console devices. Furthermore, this study is one of the first to demonstrate these relationships and test them simultaneously

  20. Nostalgia Videogames as Playable Game Criticism

    Directory of Open Access Journals (Sweden)

    Robin J.S. Sloan

    2016-11-01

    Full Text Available The aim of this paper is to consider the emergence of nostalgia videogames in the context of playable game criticism. Mirroring the development of the nostalgia film in cinema, an increasing number of developers are creating videogames that are evocative of past gaming forms, designs, and styles. The primary focus of this paper is to explore the extent to which these nostalgia videogames could be considered games-on-games: games that offer a critical view on game design and development, framed by the nostalgia and cultural memory of both gamers and game developers. Theories of pastiche and parody as applied to literature, film, and art are used to form a basis for the examination of recent nostalgia videogames, all of which demonstrate a degree of reflection on the videogame medium.

  2. Are videogame training gains specific or general?

    Directory of Open Access Journals (Sweden)

    Adam C. Oei

    2014-04-01

    Full Text Available Many recent studies using healthy adults document enhancements in perception and cognition from playing commercial action videogames. Playing action games (e.g., Call of Duty, Medal of Honor is associated with improved bottom-up lower-level information processing skills like visual-perceptual and attentional processes. One proposal states a general improvement in the ability to interpret and gather statistical information to predict future actions which then leads to better performance across different perceptual/attentional tasks. Another proposal claims all the tasks are separately trained in the action videogames because the action videogames and laboratory tasks contain similar demands. We review studies of action and non-action videogames to show support for the latter proposal. To explain transfer in action videogames, we argue that the perceptual and attention tasks share common demands with the trained videogames (e.g., multiple object tracking, rapid attentional switches, and peripheral vision. In non-action videogames, several studies also demonstrate specific, limited transfer. One instance of specific transfer is the specific enhancement to mental rotation after training in games with a spatial emphasis (e.g, Tetris. In contrast, the evidence for transfer is equivocal where the game and task do not share common demands (e.g., executive functioning. Thus, the common demands hypothesis of transfer not only characterizes transfer effects in action videogames, but also non-action games. Furthermore, such a theory provides specific predictions, which can help in the selection of games to train human cognition as well as in the design of videogames purposed for human cognitive and perceptual enhancement. Finally this hypothesis is consistent with the cognitive training literature where most post-training gains are for tasks similar to the training rather than general, non-specific improvements.

    Increase in internet use and video-gaming contributes to public concern on pathological or obsessive play of video games among children and adolescents worldwide. Nevertheless, little is known about the prevalence of pathological symptoms in video-gaming among Singaporean youth and the psychometric properties of instruments measuring pathological symptoms in video-gaming. A total of 2998 children and adolescents from 6 primary and 6 secondary schools in Singapore responded to a comprehensive survey questionnaire on sociodemographic characteristics, video-gaming habits, school performance, somatic symptoms, various psychological traits, social functioning and pathological symptoms of video-gaming. After weighting, the survey data were analysed to determine the prevalence of pathological video-gaming among Singaporean youth and gender differences in the prevalence. The construct validity of instrument used to measure pathological symptoms of video-gaming was tested. Of all the study participants, 8.7% were classified as pathological players with more boys reporting more pathological symptoms than girls. All variables, including impulse control problem, social competence, hostility, academic performance, and damages to social functioning, tested for construct validity, were significantly associated with pathological status, providing good evidence for the construct validity of the instrument used. The prevalence rate of pathological video-gaming among Singaporean youth is comparable with that from other countries studied thus far, and gender differences are also consistent with the findings of prior research. The positive evidence of construct validity supports the potential use of the instrument for future research and clinical screening on Singapore children and adolescents' pathological video-gaming.

    1999-01-01

    We aimed to elucidate the mechanisms underlying video-game epilepsy by comparing the flicker- and spatial-frequency ranges over which photic and pattern stimulation elicited photoparoxysmal responses in two different populations: (a) 25 patients with a history of seizures experienced while playing video games; and (b) 25 age- and medication-matched controls with a history of photosensitive epilepsy, but no history of video-game seizures. Abnormality ranges were determined by measuring photoparoxysmal EEG abnormalities as a function of the flicker frequency of patterned and diffuse intermittent photic stimulation (IPS) and the spatial frequency of patterns on a raster display. There was no significant difference between the groups in respect of the abnormality ranges elicited by patterned or diffuse IPS or by spatial patterns. When the groups were compared at one specific IPS frequency (-50 Hz), however, the flicker frequency of European television displays, the video-game patients were significantly more likely to be sensitive. The results suggest that video-game seizures are a manifestation of photosensitive epilepsy. The increased sensitivity of video-game patients to IPS at 50 Hz indicates that display flicker may underlie video-game seizures. The similarity in photic- and pattern-stimulation ranges over which abnormalities are elicited in video-game patients and controls suggests that all patients with photosensitive epilepsy may be predisposed toward video-game-induced seizures. Photosensitivity screening should therefore include assessment by using both IPS at 50 Hz and patterns displayed on a television or monitor with a 50-Hz frame rate.

    Emilie A Bard-Chapeau

    Full Text Available The ecotropic viral integration site 1 (Evi1 oncogenic transcription factor is one of a number of alternative transcripts encoded by the Mds1 and Evi1 complex locus (Mecom. Overexpression of Evi1 has been observed in a number of myeloid disorders and is associated with poor patient survival. It is also amplified and/or overexpressed in many epithelial cancers including nasopharyngeal carcinoma, ovarian carcinoma, ependymomas, and lung and colorectal cancers. Two murine knockout models have also demonstrated Evi1's critical role in the maintenance of hematopoietic stem cell renewal with its absence resulting in the death of mutant embryos due to hematopoietic failure. Here we characterize a novel mouse model (designated Evi1(fl3 in which Evi1 exon 3, which carries the ATG start, is flanked by loxP sites. Unexpectedly, we found that germline deletion of exon3 produces a hypomorphic allele due to the use of an alternative ATG start site located in exon 4, resulting in a minor Evi1 N-terminal truncation and a block in expression of the Mds1-Evi1 fusion transcript. Evi1(δex3/δex3 mutant embryos showed only a mild non-lethal hematopoietic phenotype and bone marrow failure was only observed in adult Vav-iCre/+, Evi1(fl3/fl3 mice in which exon 3 was specifically deleted in the hematopoietic system. Evi1(δex3/δex3 knockout pups are born in normal numbers but die during the perinatal period from congenital heart defects. Database searches identified 143 genes with similar mutant heart phenotypes as those observed in Evi1(δex3/δex3 mutant pups. Interestingly, 42 of these congenital heart defect genes contain known Evi1-binding sites, and expression of 18 of these genes are also effected by Evi1 siRNA knockdown. These results show a potential functional involvement of Evi1 target genes in heart development and indicate that Evi1 is part of a transcriptional program that regulates cardiac development in addition to the development of blood.

    Kusnezov, D.; Lewenkopf, C.H.

    1996-01-01

    A general formulation of translationally invariant, parametrically correlated random matrix ensembles, is used to classify universality in correlation functions. Surprisingly, the range of possible physical systems is bounded, and can be labeled by a parameter α element-of(0,2), in a manner analogous to Lacute evy diffusion. Universality is obtained after scaling by the (anomalous) diffusion constant D α (the usual scaling is divergent for α<2). For each α, correlation functions are universal, and distinct. The previous results in the literature correspond to the limiting case of superdiffusion, α=2. copyright 1996 The American Physical Society

  13. A Gameplay Definition through Videogame Classification

    Damien Djaouti

    2008-01-01

    Full Text Available This paper is part of an experimental approach aimed to raise a videogames classification. Being inspired by the methodology that Propp used for the classification of Russian fairy tales, we have identified recurrent diagrams within rules of videogames, that we called “Gameplay Bricks”. The combinations of these different bricks should allow us to represent a classification of all videogames in accordance with their rules. In this article, we will study the nature of these bricks, especially the link they seem to have with two types of game rules: the rules that allow the player to “manipulate” the elements of the game, and the rules defining the “goal” of the game. This study will lead to an hypothesis about the nature of gameplay.

  14. Videogame interventions and spatial ability interactions

    Thomas S. Redick

    2014-03-01

    Full Text Available Numerous research studies have been conducted on the use of videogames as tools to improve one’s cognitive abilities. While meta-analyses and qualitative reviews have provided evidence that some aspects of cognition such as spatial imagery are modified after exposure to videogames, other evidence has shown that matrix reasoning measures of fluid intelligence do not show evidence of transfer from videogame training. In the current work, we investigate the available evidence for transfer specifically to nonverbal intelligence and spatial ability measures, given recent research that these abilities may be most sensitive to training on cognitive and working memory tasks. Accordingly, we highlight a few studies that on the surface provide evidence for transfer to spatial abilities, but a closer look at the pattern of data does not reveal a clean interpretation of the results. We discuss the implications of these results in relation to research design and statistical analysis practices.

    Full Text Available Childhood obesity is one of the most dangerous pathologies; it can lead to serious illness in the absence of medical support. In this article we give an overview of the use of videogames for reducing and normalizing the weight of overweight and obese children. We discuss the categorization of the existing games and their limits, and we outline the perspectives of psychopedagogical research in the domain of game design for treating obese and overweight children. The role of long-term motivation in the treatment of obesity is one of the crucial questions we discuss. We try to understand how videogames can help children and parents maintain motivation during weight-loss treatment. The role of parents is undeniable in ensuring the success of weight-loss programs for overweight or obese children. Perhaps videogames can be the instrument for families’ lifestyle changes.

  16. Acetylation of the proto-oncogene EVI1 abrogates Bcl-xL promoter binding and induces apoptosis.

    Directory of Open Access Journals (Sweden)

    Anjan Kumar Pradhan

    Full Text Available EVI1 (Ecotropic Viral Integration site I, which was originally identified as a myeloid transforming gene by means of retroviral insertional mutagenesis in mouse leukemia, encodes a nuclear DNA binding zinc finger protein. The presence of zinc fingers that are able to bind to specific sequences of DNA suggests that EVI1 is a transcriptional regulator; however, except a few, target genes of EVI1 are poorly functionally identified thus far. In this study we provide evidence that EVI1 directly induces the expression of Bcl-xL through the first set of zinc finger and thereby inhibits apoptosis. ChIP analysis showed that EVI1 binds to the Bcl-xL promoter in HT-29 cells, a colon carcinoma cell line, which expresses EVI1. The observation is also supported by the fact that EVI1 siRNA treated HT-29 cells, shows a down regulation of Bcl-xL expression and that over expression of EVI1 results in the induction of the Bcl-xL reporter construct. A set of EVI1 positive chronic myeloid leukemia (CML samples also showed higher Bcl-xL expression with respect to EVI1 negative samples. Interestingly, co-expression of EVI1 with wild type, but not with dominant-negative form of PCAF, abolishes the effect of EVI1 on Bcl-xL, indicating that acetylation of EVI1 abrogates its ability not only to bind Bcl-xL promoter but also alleviate Bcl-xL activity. Finally we have shown that EVI1 expression regulates apoptosis in HT-29 cells, which is abrogated when HT-29 cells are transfected with EVI1 siRNA or PCAF. The result for the first time shows a direct pathway by which EVI1 can protect cells from apoptosis and also demonstrates that the pathway can be reversed when EVI1 is acetylated.

    Emotion regulation (ER) supports multiple individual functions and promotes mental health and wellbeing. Among the tools that may be used to help people in managing their affective states, videogames are reaching attention and are showing positive effects. Yet, little is known about their effectiveness. This study aims to assess the amount and quality of studies investigating the effects and modalities of the use of videogames for ER. A systematic literature search according to PRISMA guidelines was performed. Subsequently, according to expert advice other few studies have been added. Twenty-three studies met the inclusion criteria and were included in the review; they can be categorized into three groups, namely (1) cross-sectional and qualitative studies, (2) experimental studies investigating the effects of videogame experience on ER and (3) ER intervention with serious games. Discussion of the reviewed studies highlights that frequent gaming with commercial games offers more opportunities for ER improvement (related to gameplay and enjoyment of fictional properties) than limited-time experiences, such as those supported by bespoke serious games. This research area is still in its infancy and findings need to be interpreted with caution; furthermore, future reviews are encouraged to include clinical populations. Videogames offer several opportunities for ER and a challenge for educational and psychological interventions.

    Full Text Available This study aims to fill a gap in the current research on the personality organization of frequent videogame users. The scientific literature in this area refers only to the existence of risk factors that increase the likelihood of abusing videogames and their negative consequences on the mental health of users (Gentile et al., 2011; Lemmens, Valkenburg, & Peter, 2011; Rehbein & Baier, 2013. In this study, a sample of patients who reported spending an excessive amount of their time playing videogames were recruited from Instituto Quintino Aires–Lisbon/Oporto and took the Rorschach Personality Test (Exner, 1993, 1995. Two other samples—one consisting of patients who reported not playing videogames, and the other of patients who were discharged from the institution after psychotherapy—also took part in the study. The patients in the first sample revealed less exposure to the relational sources of stress that are necessary for socioemotional development and less interest in others than did patients in the other samples. Other results regarding the personality structure of the subjects in the three samples are compared and discussed in light of cultural-historical psychology.

    Game mechanics have been identified as "methods invoked by agents for interacting with the game world."(1) They are elements of game play that provide a primary source of interactivity and structure how videogames proceed. Many kinds of game mechanics have been generated. Some provide fun or enjoyment, others may provide excitement or even suspense (i.e., emotional aspects of game play), whereas some are guided by principles of behavior change theory. Game mechanics that succeed in off-the-shelf entertainment videogames, however, may not work in serious games, such as games for health (G4H). Although game mechanics are key to a serious videogame's success, maintaining a balance between the serious intent of the game while keeping it fun, there has been little attention to game mechanics in the academic G4H literature. Several eminent games for health developers (academics and nonacademics) were asked to share their experiences in regard to game mechanics in the serious videogames they have developed.

  6. Analysis on Difference of Forest Phenology Extracted from EVI and LAI Based on PhenoCams

    Land surface phenology can make up for the deficiency of field observation with advantages of capturing the continuous expression of phenology on a large scale. However, there are some variability in phenological metrics derived from different satellite time-series data of vegetation parameters. This paper aims at assessing the difference of phenology information extracted from EVI and LAI time series. To achieve this, some web-camera sites were selected to analyze the characteristics between MODIS-EVI and MODIS-LAI time series from 2010 to 2014 for different forest types, including evergreen coniferous forest, evergreen broadleaf forest, deciduous coniferous forest and deciduous broadleaf forest. At the same time, satellite-based phenological metrics were extracted by the Logistics algorithm and compared with camera-based phenological metrics. Results show that the SOS and EOS that are extracted from LAI are close to bud burst and leaf defoliation respectively, while the SOS and EOS that are extracted from EVI is close to leaf unfolding and leaf coloring respectively. Thus the SOS that is extracted from LAI is earlier than that from EVI, while the EOS that is extracted from LAI is later than that from EVI at deciduous forest sites. Although the seasonal variation characteristics of evergreen forests are not apparent, significant discrepancies exist in LAI time series and EVI time series. In addition, Satellite- and camera-based phenological metrics agree well generally, but EVI has higher correlation with the camera-based canopy greenness (green chromatic coordinate, gcc) than LAI.

    Expression of the MECOM (also known as EVI1) proto-oncogene is deregulated by chromosomal translocations in some cases of acute myeloid leukemia (AML) and is associated with poor clinical outcome. Here, through transcriptomic and metabolomic profiling of hematopoietic cells, we reveal that EVI1 overexpression alters cellular metabolism. A screen using pooled short hairpin RNAs (shRNAs) identified the ATP-buffering, mitochondrial creatine kinase CKMT1 as necessary for survival of EVI1-expressing cells in subjects with EVI1-positive AML. EVI1 promotes CKMT1 expression by repressing the myeloid differentiation regulator RUNX1. Suppression of arginine-creatine metabolism by CKMT1-directed shRNAs or by the small molecule cyclocreatine selectively decreased the viability, promoted the cell cycle arrest and apoptosis of human EVI1-positive cell lines, and prolonged survival in both orthotopic xenograft models and mouse models of primary AML. CKMT1 inhibition altered mitochondrial respiration and ATP production, an effect that was abrogated by phosphocreatine-mediated reactivation of the arginine-creatine pathway. Targeting CKMT1 is thus a promising therapeutic strategy for this EVI1-driven AML subtype that is highly resistant to current treatment regimens.

    Video-games are becoming a common tool to guide patients through rehabilitation because of their power of motivating and engaging their users. Video-games may also be integrated into an infrastructure that allows patients, discharged from the hospital, to continue intensive rehabilitation at home under remote monitoring by the hospital itself, as suggested by the recently funded Rewire project. Goal of this work is to describe a novel low cost platform, based on video-games, targeted to neglect rehabilitation. The patient is guided to explore his neglected hemispace by a set of specifically designed games that ask him to reach targets, with an increasing level of difficulties. Visual and auditory cues helped the patient in the task and are progressively removed. A controlled randomization of scenarios, targets and distractors, a balanced reward system and music played in the background, all contribute to make rehabilitation more attractive, thus enabling intensive prolonged treatment. Results from our first patient, who underwent rehabilitation for half an hour, for five days a week for one month, showed on one side a very positive attitude of the patient towards the platform for the whole period, on the other side a significant improvement was obtained. Importantly, this amelioration was confirmed at a follow up evaluation five months after the last rehabilitation session and generalized to everyday life activities. Such a system could well be integrated into a home based rehabilitation system.

    Full Text Available The ecotropic virus integration site 1 (EVI1 transcription factor is associated with human myeloid malignancy of poor prognosis and is overexpressed in 8-10% of adult AML and strikingly up to 27% of pediatric MLL-rearranged leukemias. For the first time, we report comprehensive genomewide EVI1 binding and whole transcriptome gene deregulation in leukemic cells using a combination of ChIP-Seq and RNA-Seq expression profiling. We found disruption of terminal myeloid differentiation and cell cycle regulation to be prominent in EVI-induced leukemogenesis. Specifically, we identified EVI1 directly binds to and downregulates the master myeloid differentiation gene Cebpe and several of its downstream gene targets critical for terminal myeloid differentiation. We also found EVI1 binds to and downregulates Serpinb2 as well as numerous genes involved in the Jak-Stat signaling pathway. Finally, we identified decreased expression of several ATP-dependent P2X purinoreceptors genes involved in apoptosis mechanisms. These findings provide a foundation for future study of potential therapeutic gene targets for EVI1-induced leukemia.

    The present study examined whether action videogames can improve multi-tasking in high workload environments. Two groups with no action videogame experience were pre-tested using the Multi-Attribute Task Battery (MATB). It consists of two primary tasks; tracking and fuel management, and two secondary tasks; systems monitoring and communication. One group served as a control group, while a second played action videogames a minimum of 5 h a week for 10 weeks. Both groups returned for a post-assessment on the MATB. We found the videogame treatment enhanced performance on secondary tasks, without interfering with the primary tasks. Our results demonstrate action videogames can increase people's ability to take on additional tasks by increasing attentional capacity. Copyright © 2012 Elsevier Ltd and The Ergonomics Society.

  3. Are videogame training gains specific or general?

    Science.gov (United States)

    Oei, Adam C; Patterson, Michael D

    2014-01-01

    Many recent studies using healthy adults document enhancements in perception and cognition from playing commercial action videogames (AVGs). Playing action games (e.g., Call of Duty, Medal of Honor) is associated with improved bottom-up lower-level information processing skills like visual-perceptual and attentional processes. One proposal states a general improvement in the ability to interpret and gather statistical information to predict future actions which then leads to better performance across different perceptual/attentional tasks. Another proposal claims all the tasks are separately trained in the AVGs because the AVGs and laboratory tasks contain similar demands. We review studies of action and non-AVGs to show support for the latter proposal. To explain transfer in AVGs, we argue that the perceptual and attention tasks share common demands with the trained videogames (e.g., multiple object tracking (MOT), rapid attentional switches, and peripheral vision). In non-AVGs, several studies also demonstrate specific, limited transfer. One instance of specific transfer is the specific enhancement to mental rotation after training in games with a spatial emphasis (e.g., Tetris). In contrast, the evidence for transfer is equivocal where the game and task do not share common demands (e.g., executive functioning). Thus, the "common demands" hypothesis of transfer not only characterizes transfer effects in AVGs, but also non-action games. Furthermore, such a theory provides specific predictions, which can help in the selection of games to train human cognition as well as in the design of videogames purposed for human cognitive and perceptual enhancement. Finally this hypothesis is consistent with the cognitive training literature where most post-training gains are for tasks similar to the training rather than general, non-specific improvements.

    With the introduction of Nintendo video-games on a large scale, reports of children having seizures while playing suggested a possible specific, provocative factor. Although 50% of the photosensitive patients are also sensitive to a 50-Hz television, nonphotosensitive patients with a history of video-game seizures were described as well. The question arises whether this is a mere coincidence, provoked by fatigue and stress, is related to the reaction to the television screen itself, or depends on the movement and color of the pictures of this specific game. A European study was performed in four countries and five sites. All patients were selected because of a history of television, video- or computer-game seizures, with a history of sun-light-, discotheque-, or black and white pattern-evoked seizures, or were already known to be sensitive to intermittent photic stimulation.

Because of that, the aim of this article was to analyze the game “Kinect Sports” of Xbox 360, about some athletics events, compare it with the official events and identify the pedagogical possibilities. Two steps were organized to do this research: data collection (visual methods and participant observation and thematic analysis. For a better way of presentation, the results were first organized by the athletics events. Each of those events was analyze with 3 themes: description, comparisons and pedagogical possibilities. The videogame can be an important resource for the Physical Education teacher, because it is a different strategy that can contribute for the exploration of the athletics universe.

    eviQ Cancer Treatments Online is a free, web-based resource providing access to over 600 evidence-based treatment protocols in medical oncology, radiation oncology, hematology and cancer genetics. With over 60 000 registrants from 148 countries, eviQ is widely used by cancer clinicians globally. The aim of this study was to examine the perceived quality of eviQ by Australian medical oncologists, the impact it had on their knowledge and practice, and the effect it had on their patients. A web-based survey was administered to members of the Medical Oncology Group of Australia by email. Two reminders emails were sent to encourage participation. Of the 97 respondents (15%), all but one, were practicing in Australia, with varying years of oncology experience (10 years: 39%). eviQ was most frequently used as a source for providing patient information sheets on chemotherapy side effects, with 57% of respondents using eviQ for this purpose. Other uses included accessing side effect information (27%), checking drug doses (26%) and guiding dose adjustments (22%). The majority of respondents rated eviQ as current, accurate and relevant with over 90% agreeing that eviQ was of a high quality. Most of the respondents reported that they provided better care with enhanced patient experiences as a result of using eviQ. eviQ was highly regarded by Australian medical oncologists who responded to our survey. The results suggested that usage of eviQ had a positive impact on individual knowledge, practice and promoted better patient-centered care. © 2017 John Wiley & Sons Australia, Ltd.

    There are potential benefits of playing videogames for health improvement such as increasing knowledge about health-related issues by playing educational games and fighting a sedentary lifestyle by playing exergames. The number of systematic review articles about "videogames" and "health improvement" is limited. Therefore, the purpose of this study is to review those randomized controlled trials (RCTs) with the topic of "videogames" and "health improvement." Several electronic databases were searched for RCTs testing videogames on health outcomes that were published in English between January 2000 and April 2012. Forty-five articles met the eligibility criteria and were categorized into five groups: (1) videogames and patient pain and stress reduction (nine articles), (2) videogames and patient behavioral change (19 articles), (3) videogames and patient rehabilitation (eight articles), (4) videogames as diagnostic tools (three articles), and (5) videogames and cognitive ability (six articles). Most of the articles have shown promising results in using videogames within various fields of healthcare. Although exergames are the most prominent choice regarding health improvement, videogames have the potential to be used as a pain management tool, diagnostic tool, or educational tool. They also can be used as a facilitator in physical rehabilitation or cognitive loss prevention. More RCTs are needed to fully uncover the benefits of using videogames for improving patients' health.

    The aims of this study were twofold: (1) to compare the physiological costs of active videogames (AVGs) and sedentary videogames (SVGs) and (2) to compare the exercise intensities attained during AVGs with the exercise intensity criteria for moderate and vigorous physical activity, as stated in current physical activity recommendations for improving public health. Nineteen young males participated in the study (age, 23 ± 3 years; height, 178 ± 6 cm; weight, 78 ± 15 kg). Participants completed a maximum oxygen uptake ([Formula: see text]) test and a gaming session, including AVGs ("Reflex Ridge," "River Rush," and "Boxing" for the Microsoft [Redmond, WA] Kinect™) and SVGs ("FIFA 14" [Electronic Arts, Burnaby, BC, Canada] and "Call of Duty" [Activision, Santa Monica, CA]). Heart rate (HR) and oxygen uptake [Formula: see text]) were recorded continuously during all videogames. Rating of perceived exertion (RPE) was taken every 3 minutes during AVGs and SVGs. Energy expenditure (EE), expressed as metabolic equivalents (METs), was calculated. One MET was defined as the volume of oxygen consumed at rest in a seated position and is equal to 3.5 mL of O2/kg of body mass/minute. The exercise intensity for each game was expressed as a percentage of [Formula: see text] and percentage of age-predicted maximum HR (HRmax). Exercise intensity (percentage HRmax, percentage [Formula: see text], and RPE) and EE (METs) were significantly higher during active gaming compared with sedentary gameplay (P < 0.01). AVGs elicited moderate levels of exercise intensity (64-72 percent HRmax) in line with current recommended physical activity guidelines. Our results indicate AVGs provoke physiological responses equivalent to a moderate-intensity physical activity.

    This paper addresses a different point of view of videogames, specifically serious games for health. This paper contributes to that area with a multidisciplinary perspective focus on neurosciences and computation. The experiment population has been pre-adolescents between the ages of 8 and 12 without any cognitive issues. The experiment consisted in users playing videogames as well as performing traditional psychological assessments; during these tasks the frontal brain activity was evaluated. The main goal was to analyse how the frontal lobe of the brain (executive function) works in terms of prominent cognitive skills during five types of game mechanics widely used in commercial videogames. The analysis was made by collecting brain signals during the two phases of the experiment, where the signals were analysed with an electroencephalogram neuroheadset. The validated hypotheses were whether videogames can develop executive functioning and if it was possible to identify which kind of cognitive skills are developed during each kind of typical videogame mechanic. The results contribute to the design of serious games for health purposes on a conceptual level, particularly in support of the diagnosis and treatment of cognitive-related pathologies.

    Videogames have historically gained popularity thanks to their entertainment rather than their educational value. This may be due, in part, to the fact that many educational videogames present academic concepts in dry, quiz-like ways, without the visual experiences, interactivity, and excitement of non-educational games. The increasing availability of tools that allow designers to easily create rich experiences for players now makes it simpler than ever for educational game designers to generate the visual experiences, interactivity, and excitement that gamers have grown to expect. Based on data from our work, when designed effectively, educational games can engage players, teach concepts, and tear down the stereotype of the stuffy, boring educational game. Our team has been experimenting with different ways to present scientific and mathematical concepts to middle and high school students through engaging, interactive games. When designing a gameplay concept, we focus on what we want the player to learn and experience as well as how to maintain a learning environment that is fun and engaging. Techniques that we have found successful include the use of a series of fast-paced 'minigames,' and the use of a 'simulator' learning method that allows a player to learn by completing objectives similar to those completed by today's scientists. Formative evaluations of our games over the past year have revealed both design strengths and weaknesses. Based on findings from a systematic evaluation of game play with diverse groups, with data collected through in-person observations of game play, knowledge assessments, focus groups, interviews with players, and computer tracking of students' game play behavior, we have found that players are uniformly enthusiastic about the educational tools. At the same time, we find there is more work to be done to make our tools fully intuitive, and to effectively present complex mathematical and scientific concepts to learners from a wide

    Active videogames have the potential to enhance population levels of physical activity but have not been successful in achieving this aim to date. This article considers a range of principles that may be important to the design of effective and efficient active videogames from diverse discipline areas, including behavioral sciences (health behavior change, motor learning, and serious games), business production (marketing and sales), and technology engineering and design (human-computer interaction/ergonomics and flow). Both direct and indirect pathways to impact on population levels of habitual physical activity are proposed, along with the concept of a game use lifecycle. Examples of current active and sedentary electronic games are used to understand how such principles may be applied. Furthermore, limitations of the current usage of theoretical principles are discussed. A suggested list of principles for best practice in active videogame design is proposed along with suggested research ideas to inform practice to enhance physical activity.

    2014-01-01

    This paper is a review of the state of play of research linking videogaming and flourishing, and explores the role of videogames and technology to improve mental health and well-being. Its purpose is to develop understandings about the positive intersection of gaming and well-being, to document evidence regarding links between videogames and positive mental health, and to provide guidelines for use by other researchers as they design and use tools and games to improve mental health and well-being. Using Huppert's (Huppert and So, 2013) proposition that to flourish is more than the absence of mental disorder but rather a combination of feeling good and functioning effectively, resulting in high levels of mental well-being, and Seligman's (Seligman, 2011) PERMA theory of well-being, the paper identifies strengths in existing games that generate positive affect, positive functioning, and positive social functioning, contributing to, and supporting mental health and well-being.

    Early qualitative work has suggested that videogame players see the concept of health as an important part of the gaming interface, but the way health is shown in games is commonly considered to be simplistic. The aim of this study is to explore further ways in which the concept of health is represented in videogames beyond its most common usage in the interface. Ten videogames were analyzed for content in mobility, ability, psychology, social, and pain dimensions by coding 15 minutes of videotaped play. Pain was the category that was overwhelmingly represented in this sample, with the social category the second most common. Further work is needed to explore the impact on play experience.

    Full Text Available Le nuove tecnologie, attraverso i videogiochi narrativi, permettono l’accesso a quel territorio altamente simbolico e metaforico al quale appartengono il mito e la fabula, intesa nel senso più ampio, ma anche più tradizionale, del termine. Le storie narrate dai videogame, però, proprio perché supportate da un nuovo strumento mediatico, non si limitano a ribadire consuete categorie epistemologiche, ma acquistano nuovi statuti e rinnovano le proprie funzioni, anche in ambito educativo. In particolare è la presenza di labirinti a ristabilire l’importanza dei rituali iniziatici come imprescindibili momenti di crescita. L’ipotesi è quella che, sebbene si tratti di un’iniziazione indiretta, il superamento delle prove, la soluzione degli enigmi, la sconfitta delle proprie paure più profonde, tenda a ricreare tutte le fasi che caratterizzavano il passaggio all’età adulta nelle società tradizionali e, in un certo senso, possa dimostrarsi, per le attuali generazioni, un aiuto effettivo al processo di crescita.

It placed games in the category of Arts in Media among "documentaries and dramatic narratives; media created for theatrical release; performance programs; artistic segments for use within existing series; multi-part webisodes; installations; and short films". This context defines the nature of videogame art – generally thought of in terms of expression through narration and performance – relatively well.

    2014-01-01

    Extreme climatic events triggered by global climate change are expected to increase significantly hence research into vegetation response is crucial to evaluate environmental risk. Yunnan province, locating in southwest China, experienced an extreme drought event (from autumn of 2009 to spring of 2010), with the lowest percentage rainfall anomaly and the longest non-rain days in the past 50 years. This study aimed to explore the characteristics and differences in the response to drought of four land cover types in Yunnan province, including forest, grassland, shrub, and cropland during the period 2001-2011. We used remote sensing data, MODIS-derived EVI (Enhanced Vegetation Index) to study the vegetation responses to this extreme drought event. The EVI time series were decomposed into trend, seasonal and remainder components using BFAST (Breaks For Additive Seasonal and Trend) which accounts for seasonality and enables the detection of trend changes within the time series. The preliminary results showed that: (1) BFAST proved to be capable of detecting drought-induced trend changes in EVI time series. (2) Changes in the trend component over time consisted of both gradual and abrupt changes. (3) Different spatial patterns were found for abrupt and gradual changes. (4) Cropland exhibited an abrupt change, due to its sensitivity to severe drought, while the forest seemed least affected by the extreme drought

    Steiner, Nyle A.

    2004-05-01

    The Electronic Valve Instrument (EVI) is an electronic musical wind instrument with playing techniques similar to that of a trumpet. Invented by Nyle Steiner in the early 1970's, it was designed to give the performer control of dynamics from breath pressure and the ability to make a humanly generated vibrato. Other musical paramaters can be controlled as well. It has a playing range of seven octaves (similar to that of a piano). When musical lines are played using this instrument (controller) connected to an electronic music synthesizer, the sound is much more natural sounding and expressive than when a normal musical keyboard is used. The evolution of this instrument from the pre-Midi era to it latest Midi configuration, principles of operation, synthesizer programming, and its wide use in movie and TV scoring will be discussed. The EVI has played featured musical lines in many major movie soundtracks and TV shows such as Apocalypse Now, Witness, Dead Poets Society, Fatal Attraction, No Way Out, Gorillas in the Mist, and many others. The EVI design has also been adapted as an Electronic Woodwind Instrument (EWI) by Nyle Steiner and has been manufactured and sold worldwide by the AKAI Co. in Japan.

  13. Effector CD8^+ T cells migrate via chemokine-enhanced generalized L'evy walks

    2012-02-01

    Chemokines play a central role in regulating processes essential to the immune function of T cells, such as their migration within lymphoid tissues and targeting of pathogens in sites of inflammation. In order to understand the role of the chemokine CXCL10 during chronic infection by the parasite T. gondii, we analyze tracks of migrating CD8^+ T cells in brain tissue. Surprisingly, we find that T cell motility is not described by a Brownian walk, but instead is consistent with a generalized L'evy walk consisting of L'evy-distributed runs alternating with pauses of L'evy-distributed durations. According to our model, this enables T cells to find rare targets more than an order of magnitude more efficiently than Brownian random walkers. The chemokine CXCL10 increases the migration speed without changing the character of the walk statistics. Thus, CD8^+ T cells use an efficient search strategy to facilitate an effective immune response, and CXCL10 aids them in shortening the average time to find rare targets.

  14. EVI1 inhibits apoptosis induced by antileukemic drugs via upregulation of CDKN1A/p21/WAF in human myeloid cells.

    Directory of Open Access Journals (Sweden)

    Anna Rommer

    Full Text Available Overexpression of ecotropic viral integration site 1 (EVI1 is associated with aggressive disease in acute myeloid leukemia (AML. Despite of its clinical importance, little is known about the mechanism through which EVI1 confers resistance to antileukemic drugs. Here, we show that a human myeloid cell line constitutively overexpressing EVI1 after infection with a retroviral vector (U937_EVI1 was partially resistant to etoposide and daunorubicin as compared to empty vector infected control cells (U937_vec. Similarly, inducible expression of EVI1 in HL-60 cells decreased their sensitivity to daunorubicin. Gene expression microarray analyses of U937_EVI1 and U937_vec cells cultured in the absence or presence of etoposide showed that 77 and 419 genes were regulated by EVI1 and etoposide, respectively. Notably, mRNA levels of 26 of these genes were altered by both stimuli, indicating that EVI1 regulated genes were strongly enriched among etoposide regulated genes and vice versa. One of the genes that were induced by both EVI1 and etoposide was CDKN1A/p21/WAF, which in addition to its function as a cell cycle regulator plays an important role in conferring chemotherapy resistance in various tumor types. Indeed, overexpression of CDKN1A in U937 cells mimicked the phenotype of EVI1 overexpression, similarly conferring partial resistance to antileukemic drugs.

    Full Text Available Resumo Os videogames são frequentemente acusados de serem prejudiciais à saúde. Sua operatividade colocaria o jogador em uma série de rotinas irracionais, muito próximas a uma relação estímulo-resposta. Sugerimos que tal posição limita as possibilidades de relação entre o videogame e a aprendizagem e está baseada em uma imagem teleológica do desenvolvimento da cognição que toma o aprender como uma caminhada em direção à racionalidade lógica. O presente artigo parte da descrição do aprendizado de um dos autores analisada a partir da retórica procedural com um jogo eletrônico para propor um modo de compreender a ação com o videogame, que convoca a uma constante recomposição do sujeito que joga e do jogo. A teoria da enação, por sua vez, apresenta proposições que sustentam uma modalidade de conhecimento operativo e incorporado, mais próximo da experiência com os videogames.

    Despite active videogames' popularity and ability to increase a player's energy expenditure, research indicates their use sharply declines over time, which limits their utility in promoting physical activity. A frequent criticism is that a player's interest is quickly exhausted. At the preconference of the International Society of Behavioral Nutrition and Physical Activity 2014, a group of investigators and videogame developers gathered to share lessons learned from using serious videogames in health behavior change and offer insight to guide future efforts.

    Full Text Available In the arid Mojave Desert, the phenological response of vegetation is largely dependent upon the timing and amount of rainfall, and maps of annual plant cover at any one point in time can vary widely. Our study developed relative annual plant growth models as proxies for annual plant cover using metrics that captured phenological variability in Moderate-Resolution Imaging Spectroradiometer (MODIS Enhanced Vegetation Index (EVI satellite images. We used landscape phenologies revealed in MODIS data together with ecological knowledge of annual plant seasonality to develop a suite of metrics to describe annual growth on a yearly basis. Each of these metrics was applied to temporally-composited MODIS-EVI images to develop a relative model of annual growth. Each model was evaluated by testing how well it predicted field estimates of annual cover collected during 2003 and 2005 at the Mojave National Preserve. The best performing metric was the spring difference metric, which compared the average of three spring MODIS-EVI composites of a given year to that of 2002, a year of record drought. The spring difference metric showed correlations with annual plant cover of R2 = 0.61 for 2005 and R2 = 0.47 for 2003. Although the correlation is moderate, we consider it supportive given the characteristics of the field data, which were collected for a different study in a localized area and are not ideal for calibration to MODIS pixels. A proxy for annual growth potential was developed from the spring difference metric of 2005 for use as an environmental data layer in desert tortoise habitat modeling. The application of the spring difference metric to other imagery years presents potential for other applications such as fuels, invasive species, and dust-emission monitoring in the Mojave Desert.

  10. Tracking Ecosystem Water Use Efficiency of Cropland by Exclusive Use of MODIS EVI Data

    Full Text Available One of the most important linkages that couple terrestrial carbon and water cycles is ecosystem water use efficiency (WUE, which is relevant to the reasonable utilization of water resources and farming practices. Eddy covariance techniques provide an opportunity to monitor the variability in WUE and can be integrated with Moderate Resolution Imaging Spectroradiometer (MODIS observations. Scaling up in situ observations from flux tower sites to large areas remains challenging and few studies have been reported on direct estimation of WUE from remotely-sensed data. This study examined the main environmental factors driving the variability in WUE of corn/soybean croplands, and revealed the prominent role of solar radiation and temperature. Time-series of MODIS-derived enhanced vegetation indices (EVI, which are proxies for the plant responses to environmental controls, were also strongly correlated with ecosystem WUE, thereby implying great potential for remote quantification. Further, both performance of the indirect MODIS-derived WUE from gross primary productivity (GPP and evapotranspiration (ET, and the direct estimates by exclusive use of MODIS EVI data were evaluated using tower-based measurements. The results showed that ecosystem WUE were overpredicted at the beginning and ending of crop-growth periods and severely underestimated during the peak periods by the indirect estimates from MODIS products, which was mainly attributed to the error source from MODIS GPP. However, a simple empirical model that is solely based on MODIS EVI data performed rather well to capture the seasonal variations in WUE, especially for the growing periods of croplands. Independent validation at different sites indicates the method has potential for broad application.

    Barab, Sasha A.; Dodge, Tyler; Ingram-Goble, Adam; Volk, Charlene; Peppler, Kylie; Pettyjohn, Patrick; Solomou, Maria

    Whereas traditionally stories involve an author, a performer, and an audience, much of the power of videogames as media for advancing narrative springs from their affordance for the player to occupy more than one role—and sometimes all three—simultaneously. In the narratively-rich videogames that we design, players have the opportunity to perform actions, experience consequences, and reflect on the underlying social values that these situations were designed to engage. Here, our focus is on the use of these games to engage children in experiencing ideological struggles associated with realizing social commitments. Toward this end, we will present our theoretical argument for the power of games as a contemporary story medium, grounding this discussion in the demonstration of three game design projects and their implementations.

  13. Childhood obesity stigma: association with television, videogame, and magazine exposure.

    Latner, Janet D; Rosewall, Juliet K; Simmonds, Murray B

    2007-06-01

    Although the stigmatization of obesity among children is highly prevalent, its origins and relationship to mass media exposure are largely unknown. Ninety boys and 171 girls aged 10-13 years (mean BMI=19.84) were asked to rank, in order of liking, 12 figures of peers depicted both with and without various disabilities or obesity, and to rate their attitudes towards the obese child on visual analogue scales. Weekly time spent watching television, watching videogames, and reading magazines on weekdays and weekends was assessed. Total media use, magazine use, and videogame use were significantly correlated with more negative reactions to obese girls and boys. Regression analyses revealed that greater dislike of obese children relative to their non-overweight peers was uniquely predicted by magazine reading time. Thus, media exposure was associated with stigmatizing attitudes towards obese children. Mass media sources may lead children to devalue and stigmatize peers with above-average body weights.

    2017-07-01

    Full Text Available We want to analyze the characteristics of nowadays learning and the construction of the social identity through the storytelling of videogames. We recognize these technologies as an “homogeneous culture discourse” that can only be understood searching the keys that move the world beyond the walls of the school. From this perspective we are interested in the new spaces of power and authority that these technologies introduce in the institutions. To understand these processes we organize the analysis around certain aspects that operate in the interaction between children and this object. These reasons will guide us in the analyses. The problem of our investigation is defined by stating that videogames are involved in the construction of the social identity of the users facilitating archetypes of identification models. These discourses, also, design learning modes that generate a microculture of practices and meanings with a particular logic different from the school culture. As educators, we are interested in understanding how students organize their behaviours and identifications once immersed in this technological culture. Furthermore, we aim at comprehending the communicative strategies developed by users when utilizing this technology. We claim that these cultural behaviours bring about consequences in academic learning. This investigation presents basic aspects of the theoretical background, underpinning the construction of the social identity in the context of the global condition and the hybridization of cultures. We point out the characteristics of the cultural scenario linking the students and the Informational Society. It also studies in depth the characteristics of the digitalization of the narrative space and the ludic area, which offer us the possibility to analyze videogames from a complex perspective. To sum up, our main interest is to ascertain the characteristics of learning within the storytelling and game narrative generated

    2014-03-01

    Full Text Available This paper is a review of the state of play of research linking videogaming and flourishing, and explores the role of videogames and technology to improve mental health and well-being. Its purpose is to develop understandings about the positive intersection of gaming and well-being, to document evidence regarding links between videogames and positive mental health, and to provide guidelines for use by other researchers as they design and use tools and games to improve mental health and well-being. Using Huppert’s (Huppert & So, 2013 proposition that to flourish is more than the absence of mental disorder but rather a combination of feeling good and functioning effectively resulting in high levels of mental well-being, and Seligman’s (Seligman, 2011 PERMA theory of well-being, the paper identifies strengths in existing games that generate positive affect, positive functioning and positive social functioning, contributing to, and supporting mental health and well-being.

    Abstract Objective Stories can serve as powerful tools for health interventions. Story immersion refers to the experience of being absorbed in a story. This is among the first studies to analyze story immersion's role in health videogames among children by addressing two main questions: Will children be more immersed when the main characters are similar to them? Do increased levels of immersion relate to more positive health outcomes? Subjects and Methods Eighty-seven 10–12-year-old African-American, Caucasian, and Hispanic children from Houston, TX, played a health videogame, “Escape from Diab” (Archimage, Houston, TX), featuring a protagonist with both African-American and Hispanic phenotypic features. Children's demographic information, immersion, and health outcomes (i.e., preference, motivation, and self-efficacy) were recorded and then correlated and analyzed. Results African-American and Hispanic participants reported higher immersion scores than Caucasian participants (P=0.01). Story immersion correlated positively (P valuesvideogame characters and players enhanced immersion and several health outcomes. Effectively embedding characters with similar phenotypic features to the target population in interactive health videogame narratives may be important when motivating children to adopt obesity prevention behaviors.

    2013-04-01

    Full Text Available The aim of this paper is to discuss the meaning of five neologisms in the domain of videogames in Spanish: título, aventura, personaje, plataforma, and rol. Our study focuses on a special type of neologism since the Spanish terms we deal with here are not strictly new words; they are what have been called sense neologisms or neosemanticisms, that is, old words taking a new sense in a different domain. These words were identified as new concepts after a process of analysis based on contextual evidence. This study of neology is based on the analysis of a corpus of press articles evaluating videogames published by the Spanish newspaper El País from 1998 to 2008. The analysis of the instances of use of domain specific terms in the corpus revealed that they acquired new senses different to those they have in other domains where they are also used. The paper explains the process of discovering the specialized meaning these words have developed in the domain of videogames and how the analysis of collocational behavior helps in the process of discovering the new sense and in the design of the definition provided.

    Full Text Available Emotions can influence the learning in a positive or a negative way, especially in the motivation to learn. Have a student motivated or not to learn “something” is one of the autonomous learnig keys. For that reason, in this article we present the design and experimentation of a 3D videogame prototype integrated into a virtual classroom with university students with the aim of analyse how the emotions produced by videogames can influence positive or negatively on the motivation to learn. We have support our research on theories regarding to afective interfaces, computer support colaborative learning (CSCL and videogames; meanwhile for the desing, development and evaluation methodology we have used the guide of Human Computer Interaction (HCI area. In particular, we have followed the User Centered Design (UCD principles. In the evaluation, we have analized the reasons of the motivation and its influence to the positive actitude on the subject. The results of evaluation shows that not only the motivation can be used positively in the learning, but frustation also, for example, can be used to produce a major persistence in the achivemment of learning goals. On the other hand, we found some problems in the perception of ludic things as a learning activity in high levels of teaching, such as univercity students.

  20. Mutation at the Evi1 locus in Junbo mice causes susceptibility to otitis media.

    Full Text Available Otitis media (OM, inflammation of the middle ear, remains the most common cause of hearing impairment in children. It is also the most common cause of surgery in children in the developed world. There is evidence from studies of the human population and mouse models that there is a significant genetic component predisposing to OM, yet nothing is known about the underlying genetic pathways involved in humans. We identified an N-ethyl-N-nitrosourea-induced dominant mouse mutant Junbo with hearing loss due to chronic suppurative OM and otorrhea. This develops from acute OM that arises spontaneously in the postnatal period, with the age of onset and early severity dependent on the microbiological status of the mice and their air quality. We have identified the causal mutation, a missense change in the C-terminal zinc finger region of the transcription factor Evi1. This protein is expressed in middle ear basal epithelial cells, fibroblasts, and neutrophil leukocytes at postnatal day 13 and 21 when inflammatory changes are underway. The identification and characterization of the Junbo mutant elaborates a novel role for Evi1 in mammalian disease and implicates a new pathway in genetic predisposition to OM.

On the other hand, EVI antibodies are either present or absent in treated patients presenting positive CS but negative CoML. Since CoML detects antibodies associated to resistance, EVI antibodies are not likely to participate in the control of T. cruzi infections although they might be induced by cross-reacting antigens of heart cells and the parasite. They are neither necessarily related to antibodies responsible for CS. Absorption with T. cruzi and heart tissue confirms the suggestion that EVI antibodies are induced by a number of antigenic determinants, most from heart structures with a minor participation of T. cruzi antigens.Anticorpos contra estruturas vasculares do coraçao e interstício de musculatura estriada (anticorpos EVI persistem em pacientes com doenças de Chagas curados por tratamento específico e que apresentam negativos o xenodiagnóstico, sorologia convencional (SC e o teste de lise mediada por complemento (LMCo. Além disso, o anticorpo EVI pode estar presente ou não em pacientes tratados que apresentam SC positiva mas LMCo negativa. Como a LMCo detecta anticorpos associados à resistência, os anticorpos EVI provavelmente não participam do controle de infecção pelo T. cruzi (embora sejam induzidos por antígenos comuns a estruturas cardíacas e ao parasita. Os anticorpos EVI não são também necessariamente relacionados aos anticorpos responsáveis pela SC.

    Directory of Open Access Journals (Sweden)

    Dawn Stobbart

    2015-07-01

    Full Text Available A decade before the first adaptation of a videogame to film (Super Mario Brothers, 1993, computer and arcade videogames were incorporated as subject matter in mainstream Hollywood films such as War Games (1983, The Terminator (1984, and The Last Starfighter (1984, presenting the new medium through a science fictional lens. While these films aired widespread anxieties about the ability of computers and videogames to start global wars and override human social structures and agency, at the same time, they offered a counterpoint to the traditional masculine hero, which this article will explore, situating the adolescent within the historical context of the 1980s, film, and videogames. The article will also consider the rhetorical questions raised by these films: the protagonist of War Games both inadvertently sets off and stops a chain of events that would lead to World War III. He does more than save the world from his own error, however: he teaches the government’s military computer to think and humanises the machine, rendering it less dangerous. When the protagonist of The Last Starfighter beats the arcade game for which the film is named, he is visited by aliens, who inform him that they planted the game in hope of finding a hero with shooting skills that can save the galaxy from its enemies. They transport him to fight that war, and he emerges a victorious hero. All of these films reinvent the adolescent as a hero, and at the same time, question the role of technology as a growing part of 1980s culture.

    Wolfe, Jasper; Kar, Kellyann; Perry, Ashleigh; Reynolds, Chelsea; Gradisar, Michael; Short, Michelle A

    2014-10-01

    The present study investigated adolescent video-game use prior to bedtime and subsequent sleep, working memory and sustained attention performance. Participants were 21 healthy, good-sleeping adolescents (16 male) aged between 15 and 20 years (M = 17.6 years, SD = 1.8). Time spent video-gaming and subsequent sleep was measured across one night in the sleep laboratory. There were significant correlations between time spent video-gaming and sleep and between video-gaming and sustained attention, but not working memory. Sleep duration, in turn, had a significant negative association with sustained attention performance. Mediation analyses revealed that the relationship between video-gaming and sustained attention was fully mediated by sleep duration. These results indicate that video-gaming affected the ability to sustain attention only in as much as it affected sleep. In order to minimise negative consequences of video-game playing, video-games should be used in moderation, avoiding use close to the sleep period, to obviate detriments to sleep and performance.

    2012-01-01

    Full Text Available The purpose of this manuscript will be to present scientific evidence regarding the effects of videogame playing on different aspects of the social life of children and adolescents, as well as the general potential psychological and physiological effects. A literature review from relevant databases has been performed, and experimental and meta-analytical studies have been scrutinized for positive and negative effects of videogames in children and adolescents. In general, it has been found that there is a billionaire videogame industry and yet, despite the worldwide popularity of videogames, research is still scarce and sometimes contradictory. Some research suggests a correlation between excess time video gaming on negative social and psychological aspects such as isolation and aggressive behavior; while other research suggests a positive association with motor learning, motor re-training and resilience. As far as physiological effects it has been reported that active videogames might promote higher energy expenditure than passive videogames; therefore, given an adequate parental instruction might provide videogames beneficial properties to combat the global epidemic of sedentary behavior and obesity. Videogames and everything related «to be» in front of a screen will be common to future generations, and therefore more systematic studies are required to determine the long-term exposure effects to these devices.

    Full Text Available The aim of the study is to develop a new instrument to measure engagement in videogame play termed as consumer videogame engagement. The study followed the scale development procedure to develop an instrument to measure the construct of consumer videogame engagement. In this study, we collected the data in two different phases comprising study 1 (n=136 and study 2 (n=270. We employed SPSS 22.0 for exploratory factor analysis using study 1 respondents to explore the factors for consumer videogame engagement and reliability analysis. Results of EFA resulted with six-factor solution. We further used SmartPLS 3.0 software on study 2 respondents to further confirm the six-factor solution as reflective measurement model on the first-order level, and three second-order formative constructs on the second-order or higher-order level as formative measurement model. Results of the reflective measurement model and formative measurement model evidenced that consumer videogame engagement has strong psychometric properties and is a valid instrument to measure engagement in videogame play. Results also confirmed that consumer videogame engagement is a multidimensional construct as well as a reflective-formative construct. The study is unique in its investigation as it develops an instrument to measure engagement in videogame play which comprises the cognitive, affective, and behavioral dimensions.

This review presents an overview of how videogame technologies can be used to address health issues contributing to reduced independence in older adults. Four themes were identified: (1) hardware, (2) software, (3) health issues addressed using videogames, and (4) clinicians' perspectives. Several recommendations have been proposed to build upon the use and integration of videogame technology into rehabilitation and training for older adults. In particular, the use of videogames for health requires an appropriate game classification system for development of games that are appropriate for the physical, cognitive, and social requirements of older adults or those living with a disability.

    There have been few evaluations of the quality of computerized decision support tools in medical oncology despite their widespread use in clinical practice. In this article, we provide an in-depth quality assessment of eviQ, an Australian web-based protocol system. We used the Appraisal of Guidelines for Research and Evaluation (AGREE-II) instrument to examine the quality of eviQ chemotherapy protocols across six domains: scope and purpose, stakeholder involvement, rigor of development, clarity of presentation, applicability, editorial independence and overall quality rating. Domain scores were categorized as high quality (scores of >70%), moderate quality (30-70%), and low quality (development process and the rigor with which protocols were developed were of moderate quality (scores of 34-37%) and the management of editorial independence and conflict of interest issues were rated in the low quality range (22%). Our evaluation demonstrated the eviQ protocol system is generally of high quality. However, we identified a number of areas in which eviQ could improve either its development processes or the means by which these processes are communicated to end-users. This research represents the first comprehensive evaluation of oncology protocols and paves the way for continued quality assurance research to ensure that these tools meet their objective of facilitating evidence-based medicine, standardizing treatment and, ultimately, improving patient outcomes. © 2011 Blackwell Publishing Asia Pty Ltd.

    Africa is facing resource problems due to increasing demand combined with potential climate-induced changes in supply. Here we aim to quantify resources in terms of net primary production (NPP [g C m-2 yr-1]) of vegetation in the Sahel region for 2000-2014. Using time series of the enhanced vegetation index (EVI) from MODIS, NPP was estimated for the Sahel region with a 500 × 500 m spatial resolution and 8-day temporal resolution. The estimates were based on local eddy covariance flux measurements from six sites in the Sahel region and the carbon use efficiency originating from a dynamic vegetation model. No significant NPP change was found for the Sahel as a region but, for sub-regions, significant changes, both increasing and decreasing, were observed. Substantial uncertainties related to NPP estimates and the small availability of evaluation data makes verification difficult. The simplicity of the methodology used, dependent on earth observation only, is considered an advantage.

    From its humble beginnings back in the early 1960’s the videogame has become one of the most successful form of HCI to date. However if we look more closely at the interactions between the game and gamer it becomes evident little has changed since the advent of SpaceWar back in 1961. These interactions are for the most part static and thus predictable, given a particular set of circumstances a game will always react in one particular manner despite anything the player may actually do.

  20. Identification of two critically deleted regions within chromosome segment 7q35-q36 in EVI1 deregulated myeloid leukemia cell lines.

    Directory of Open Access Journals (Sweden)

    An De Weer

    Full Text Available Chromosomal rearrangements involving the EVI1 proto-oncogene are a recurrent finding in myeloid leukemias and are indicative of a poor prognosis. Rearrangements of the EVI1 locus are often associated with monosomy 7 or cytogenetic detectable deletions of part of 7q. As EVI1 overexpression alone is not sufficient to induce leukemia, loss of a 7q tumour suppressor gene might be a required cooperating event. To test this hypothesis, we performed high-resolution array comparative genomic hybridization analysis of twelve EVI1 overexpressing patients and three EVI1 deregulated cell lines to search for 7q submicroscopic deletions. This analysis lead to the delineation of two critical regions, one of 0.39 Mb on 7q35 containing the CNTNAP2 gene and one of 1.33 Mb on chromosome bands 7q35-q36 comprising nine genes in EVI1 deregulated cell lines. These findings open the way to further studies aimed at identifying the culprit EVI1 implicated tumour suppressor genes on 7q.

    Brain responses, particularly within the orbitofrontal and cingulate cortices, to Internet video-game cues in college students are similar to those observed in patients with substance dependence in response to the substance-related cues. In this study, we report changes in brain activity between baseline and following 6 weeks of Internet video-game play. We hypothesized that subjects with high levels of self-reported craving for Internet video-game play would be associated with increased activity in the prefrontal cortex, particularly the orbitofrontal and anterior cingulate cortex. Twenty-one healthy university students were recruited. At baseline and after a 6-week period of Internet video-game play, brain activity during presentation of video-game cues was assessed using 3T blood oxygen level dependent functional magnetic resonance imaging. Craving for Internet video-game play was assessed by self-report on a 7-point visual analogue scale following cue presentation. During a standardized 6-week video-game play period, brain activity in the anterior cingulate and orbitofrontal cortex of the excessive Internet game-playing group (EIGP) increased in response to Internet video-game cues. In contrast, activity observed in the general player group (GP) was not changed or decreased. In addition, the change of craving for Internet video games was positively correlated with the change in activity of the anterior cingulate in all subjects. These changes in frontal-lobe activity with extended video-game play may be similar to those observed during the early stages of addiction.

  4. To Fatality and Beyond: The Deathsetics of Failure in Videogames

    Directory of Open Access Journals (Sweden)

    Stephen Curtis

    2015-07-01

    Full Text Available From the early static ‘Game Over’ screens of 1980s videogames to the elaborate and snuff-like voyeurism of contemporary character death videos, the end of games has always held the potential for a final realisation of the death drive that motivates the player. As technology has developed and enabled the increasing realism, or, more accurately, fidelity, of videogame visuals, a concomitant fascination with the death of the player character has arisen. My article examines the ways in which we can read the aesthetic nature of this development. The relationship between avatar deaths and visual fidelity is emblematic of the rapidly increasing economic aspects of the gaming industry. The constant deaths and restarts of the coin-op arcade games necessitated a killscreen as a financial imperative - ‘Insert coin to continue’ - but gaming’s filmic aspirations, and the accompanying budgets, seem to have reversed this relationship. Instead of frustrating the player through constant deaths, modern games do not require such a transparent application of the economics of play. It is ironic, therefore, that recent games such as Dark Souls have become so unexpectedly popular because of their willingness to kill the player. My article argues for a notion of ‘deathsetics’ predicated on the idea that death is a necessary part of the pleasure of playing games. I provide a brief history of virtual death in games and offer some explanations as to why this aspect has continued to be so central to the gaming experience.

    The aim of the present study was to develop a valid and reliable Videogame Addiction Scale for Children (VASC). The data were derived from 780 children who completed the Videogame Addiction Scale (405 girls and 375 boys; 48.1% ranging in age from 9 to 12 years). The sample was randomly split into two different sub-samples (sample 1, n  = 400; sample 2, n  = 380). Sample 1 was used to perform exploratory factor analysis (EFA) to define the factorial structure of VASC. As a result of EFA, a four-factor structure comprising 21 items was obtained and explained 55% of the total variance (the four factors being "self-control," "reward/reinforcement," "problems," and "involvement"). The internal consistency reliability of VASC has found 0.89. Confirmatory factor analysis (CFA) was performed to confirm the factorial structure obtained by EFA in the remaining half of sample ( n  = 390). The obtained fit indices from the CFA confirmed the structure of the EFA. The 21-item VASC has good psychometric properties that can be used among Turkish schoolchildren populations.

    We assessed the individual association of sedentary behaviors with the risk of overweight and excess body fat (overfat) in adolescents. A representative sample (1960 subjects, 1012 males, age 13-18.5 y) of Spanish adolescents was studied within the framework of the Alimentación y Valoración del Estado Nutricional de los Adolescentes (AVENA) study. Television (TV) watching, videogame and computer usage, doing homework, and the way students got to school, physical activity, and socioeconomic status were analyzed. Anthropometrics were measured to describe overweight (International Obesity Task Force cutoffs for body mass index) and overfat (body fat percentage >85th percentile). When all subjects were considered as an entire group, the overweight risk increased by 15.8% (P videogame usage, respectively (both Ps videogame usage (P videogames during the weekend.

    The presence of a BCR-ABL1 fusion gene is necessary for the pathogenesis of chronic myeloid leukemia (CML) through t(9;22)(q34;q11) translocation. Imatinib, an ABL tyrosine kinase inhibitor, is dramatically effective in CML patients; however, 30% of CML patients will need further treatment due to progression of CML to blast crisis (BC). Aberrant high expression of ecotropic viral integration site 1 (EVI1) is frequently observed in CML during myeloid-BC as a potent driver with a CML stem cell signature; however, the precise molecular mechanism of EVI1 transcriptional regulation during CML progression is poorly defined. Here, we demonstrate the transcriptional activity of EVI1 is dependent on activation of lymphoid enhancer-binding factor 1 (LEF1)/β-catenin complex by BCR-ABL with loss of p53 function during CML-BC. The activation of β-catenin is partly dependent on BCR-ABL expression through enhanced GSK3β phosphorylation, and EVI1 expression is directly enhanced by the LEF1/β-catenin complex bound to the EVI1 promoter region. Moreover, the loss of p53 expression is inversely correlated with high expression of EVI1 in CML leukemia cells with an aggressive phase of CML, and a portion of the activation mechanism of EVI1 expression is dependent on β-catenin activation through GSK3β phosphorylation by loss of p53. Therefore, we found that the EVI1 activation in CML-BC is dependent on LEF1/β-catenin activation by BCR-ABL expression with loss of p53 function, representing a novel selective therapeutic approach targeting myeloid blast crisis progression.

    Much of the historiography of videogames focuses on representational or participatory aspects of the genre. Here, videogames are considered as an art that is dependent on the harmony of those two seemingly separate pieces, the video and the game, with architecture servings as the fundamental link between the two. Architecture works by mobilizing distinct but simultaneous forms of attention, one aesthetic and one interactive. Looking closely at the way architecture creates immersion on a speci...

    There is emerging evidence that the psychobiological mechanisms underlying behavioral addictions such as internet and videogame addiction resemble those of addiction for substances of abuse. Review of brain imaging, treatment and genetic studies on videogame and internet addiction. Literature search of published articles between 2009 and 2013 in Pubmed using "internet addiction" and "videogame addiction" as the search word. Twenty-nine studies have been selected and evaluated under the criteria of brain imaging, treatment, and genetics. Brain imaging studies of the resting state have shown that long-term internet game playing affected brain regions responsible for reward, impulse control and sensory-motor coordination. Brain activation studies have shown that videogame playing involved changes in reward and loss of control and that gaming pictures have activated regions similarly to those activated by cue-exposure to drugs. Structural studies have shown alterations in the volume of the ventral striatum possible as result of changes in reward. Furthermore, videogame playing was associated with dopamine release similar in magnitude to those of drugs of abuse and that there were faulty inhibitory control and reward mechanisms videogame addicted individuals. Finally, treatment studies using fMRI have shown reduction in craving for videogames and reduced associated brain activity. Videogame playing may be supported by similar neural mechanisms underlying drug abuse. Similar to drug and alcohol abuse, internet addiction results in sub-sensitivity of dopamine reward mechanisms. Given the fact that this research is in its early stage it is premature to conclude that internet addiction is equivalent to substance addictions. © American Academy of Addiction Psychiatry.

    Leisure activities are underutilized as a context for intervention in the field of speech-language pathology despite the fact that leisure can be an important context for skill development. The current study investigated the perceptions of individuals with autism spectrum disorder (ASD) who play videogames as their primary leisure activity regarding the role of videogames in their lives and their motivations for playing videogames. Qualitative interview methodology was used to investigate the experiences of 10 18-24-year-olds with ASD. Information was collected about the role of videogames in the lives of adolescents and young adults with ASD and the perceived benefits of playing videogames. Results indicated the participants perceived playing videogames to have a positive impact on their lives and their development. The motivations for playing videogames described are similar to those reported by typically developing populations. Videogaming is a popular leisure pursuit for adolescents and young adults with and without ASD. Speech-language pathologists should consider how videogame play may be a useful context for teaching new communication, social, and language.

    2015-06-01

    The main objective of this study was to explore, via a systematic review of available literature, the effectiveness of videogame-based rehabilitation interventions on the motivation and health outcomes of stroke patients. Using a systematic literature review of 18 articles, we sought to address three key research questions: (1) Do videogames improve function or health outcomes among stroke survivors? (2) Do videogames increase stroke patients' motivation to engage in rehabilitation exercise and activities? (3) Which motivational techniques, principles, and theoretical frameworks have been applied in the reviewed studies? A key word search was conducted, and articles were coded for inclusion of motivational theories or principles, intervention effectiveness, and participants' motivation to perform tasks. Three motivational frameworks and principles were used (self-determination theory [SDT], flow theory, and operant conditioning) to investigate intrinsic and extrinsic approaches. Past research suggests videogame-based interventions are effective at improving and increasing a variety of health-related outcomes, including motor functioning, energy expenditure, muscle strength, and recovery times in stroke patients. Past evidence shows videogame-based interventions are a promising tool to motivate stroke patients' engagement in effective rehabilitation activities. This study also identifies an opportunity for future research to apply motivational theories from SDT to studies on stroke rehabilitation and videogames.

    In this response to Yupanqui Munoz and Charbel El-Hani's paper, "The student with a thousand faces: From the ethics in videogames to becoming a citizen", we examine their critique of videogames in science education. Munoz and El-Hani present a critical analysis of videogames such as Grand Theft Auto, Street Fight, Command and Conquer: Generals, Halo, and Fallout 3 using Neil Postman's (1993) conceptualization of technopoly along with Bill Green and Chris Bigum's (1993) notion of the cyborg curriculum. Our contention is that these games are not representative of current educational videogames about science, which hold the potential to enhance civic scientific literacy across a diverse range of students while promoting cross-cultural understandings of complex scientific concepts and phenomenon. We examine games that have undergone empirical investigation in general education science classrooms, such as River City, Quest Atlantis, Whyville, Resilient Planet, and You Make Me Sick!, and discuss the ways these videogames can engage students and teachers in a constructivist dialogue that enhances science education. Our critique extends Munoz and El-Hani's discussion through an examination of the ways videogames can enhance science education by promoting inclusive education, civic scientific literacy, and global citizenship.

    2013-05-01

    Playing action videogames is known to improve visual spatial attention and related skills. Here, we showed that playing action videogames also improves classic visual search, as well as the ability to locate targets in a dual search that mimics certain aspects of an action videogame. In Experiment 1A, first-person shooter (FPS) videogame players were faster than nonplayers in both feature search and conjunction search, and in Experiment 1B, they were faster and more accurate in a peripheral search and identification task while simultaneously performing a central search. In Experiment 2, we showed that 10 h of play could improve the performance of nonplayers on each of these tasks. Three different genres of videogames were used for training: two action games and a 3-D puzzle game. Participants who played an action game (either an FPS or a driving game) achieved greater gains on all search tasks than did those who trained using the puzzle game. Feature searches were faster after playing an action videogame, suggesting that players developed a better target template to guide search in a top-down manner. The results of the dual search suggest that, in addition to enhancing the ability to divide attention, playing an action game improves the top-down guidance of attention to possible target locations. The results have practical implications for the development of training tools to improve perceptual and cognitive skills.

    We evaluated the effects of an active videogame (AVG) intervention (Sony [Tokyo, Japan] PlayStation(®) EyeToy(®)) compared with non-AVGs on body composition, physical activity, sedentary behavior, and snack food consumption among overweight 10-12-year-old children over 24 weeks. Our research showed a treatment effect on body mass index and percentage body fat in favor of the intervention group. There was no difference between groups for total physical activity levels, but there was an increase in self-reported AVG play and reductions in non-AVG play and snack food consumption in the intervention group. Research is needed to determine how to augment the effects observed in this study.

    2016-06-01

    Energy expenditure (EE) in active videogames (AVGs) is a component for assessing its benefit for cardiovascular health. Existing evidence suggests that AVGs are able to increase EE above rest and when compared with playing passive videogames. However, the association between body movement and EE remains unclear. Furthermore, for goal-directed game design, it is important to know the contribution of body segments to EE. This knowledge will help to acquire a certain level of exercise intensity during active gaming. Therefore, the purpose of this study was to determine the best predictors of EE from body segment energies, acceleration, and heart rate during different game situations. EE and body segment movement of 17 subjects, aged 22.1 ± 2.5 years, were measured in two different AVGs. In randomized order, the subjects played a handheld-controlled Nintendo(®) Wii™ tennis (NWT) game and a whole body-controlled Sony EyeToy(®) waterfall (ETW) game. Body segment movement was analyzed using a three-dimensional motion capture system. From the video data, mean values of mechanical energy change and acceleration of 10 body segments were analyzed. Measured EE was significantly higher in ETW (7.8 ± 1.4 metabolic equivalents [METs]) than in NWT (3.4 ± 1.0 METs). The best prediction parameter for the more intense ETW game was the energy change of the right thigh and for the less intense hand-controlled NWT game was the energy change of the upper torso. Segment acceleration was less accurate in predicting EE. The best predictors of metabolic EE were the thighs and the upper torso in whole body and handheld-controlled games, respectively. Increasing movement of these body segments would lead to higher physical activity intensity during gaming, reducing sedentary behavior.

    With the support of the U.S. Department of Energy's Vehicle Technologies Office, the National Renewable Energy Laboratory (NREL) worked with the City of Columbus, Ohio, to develop a plan for the expansion of the region's network of charging stations to support increased adoption of plug-in electric vehicles (PEVs) in the local market. NREL's Electric Vehicle Infrastructure Projection (EVI-Pro) model was used to generate scenarios of regional charging infrastructure to support consumer PEV adoption. Results indicate that approximately 400 Level 2 plugs at multi-unit dwellings and 350 Level 2 plugs at non-residential locations are required to support Columbus' primary PEV goal of 5,300 PEVs on the road by the end of 2019. This analysis finds that while consumer demand for fast charging is expected to remain low (due to modest anticipated adoption of short-range battery electric vehicles), a minimum level of fast charging coverage across the city is required to ease consumer range anxiety concerns by providing a safety net for unexpected charging events. Sensitivity analyses around some key assumptions have also been performed; of these, consumer preference for PHEV versus BEV and for their electric driving range, ambient conditions, and availability of residential charging at multi-unit dwellings were identified as key determinants of the non-residential PEV charging infrastructure required to support PEV adoption. The results discussed in this report can be leveraged by similar U.S. cities as part of a strategy to accelerate PEV adoption in the light-duty vehicle market.

    Video-gaming is an increasingly prevalent activity among children and adolescents that is known to influence several areas of emotional, cognitive and behavioural functioning. Currently there is insufficient experimental evidence about how extended video-game play may affect adolescents' sleep. The aim of this study was to investigate the short-term impact of adolescents' prolonged exposure to violent video-gaming on sleep. Seventeen male adolescents (mean age = 16 ± 1 years) with no current sleep difficulties played a novel, fast-paced, violent video-game (50 or 150 min) before their usual bedtime on two different testing nights in a sleep laboratory. Objective (polysomnography-measured sleep and heart rate) and subjective (single-night sleep diary) measures were obtained to assess the arousing effects of prolonged gaming. Compared with regular gaming, prolonged gaming produced decreases in objective sleep efficiency (by 7 ± 2%, falling below 85%) and total sleep time (by 27 ± 12 min) that was contributed by a near-moderate reduction in rapid eye movement sleep (Cohen's d = 0.48). Subjective sleep-onset latency significantly increased by 17 ± 8 min, and there was a moderate reduction in self-reported sleep quality after prolonged gaming (Cohen's d = 0.53). Heart rate did not differ significantly between video-gaming conditions during pre-sleep game-play or the sleep-onset phase. Results provide evidence that prolonged video-gaming may cause clinically significant disruption to adolescent sleep, even when sleep after video-gaming is initiated at normal bedtime. However, physiological arousal may not necessarily be the mechanism by which technology use affects sleep. © 2012 European Sleep Research Society.

    Full Text Available The Normalized Difference Vegetation Index (NDVI and the Enhanced Vegetation Index (EVI have gained considerable attention in ecological research and management as proxies for landscape-scale vegetation quantity and quality. In the Greater Yellowstone Ecosystem (GYE, these indices are especially important for mapping spatiotemporal variation in the forage available to migratory elk (Cervus elaphus. Here, we examined how the accuracy of using MODIS-derived NDVI and EVI as proxies for forage biomass and quality differed across elevation-related phenology and land use gradients, determined if polynomial NDVI/EVI, site, and season effects improved these models, and then mapped spatiotemporal variation in the abundance of high quality forage available to elk across the Upper Yellowstone River Basin (UYRB of the GYE. Models with a polynomial NDVI effect explained 19%–55% more variation in biomass than the linear NDVI and EVI models. Models with linear season effect explained 14%–20% more variation in chlorophyll, 37%–69% more variation in crude protein, and 26%–50% more variation in in vitro dry matter digestibility (IVDMD than the linear NDVI and EVI models. Linear NDVI models explained more variation in biomass and quality across the UYRB than the linear EVI models. The accuracy of these models was lowest in grasslands with late onset of growth, in irrigated agriculture, and after the peak in biomass. Forage biomass and quality varied across the elevation-related phenology and land use gradients in the UYRB throughout the season. At their seasonal peak, the abundance of high quality forage for elk was 50% greater in grasslands with late onset of growth and 200% greater in irrigated agriculture than in all other grasslands, suggesting that these grasslands play an especially important role in the movement and fitness of migratory elk. These results provide novel information on the utility of NDVI and EVI for mapping spatiotemporal patterns of

    Replacing physical activity with videogaming has been implicated in causing obesity. Studies have shown that using motion-sensing controllers with activity-promoting videogames expends energy comparable to aerobic exercise; however, effects of motion-sensing controllers have not been examined with traditional (non-exercise-promoting) videogames. We measured indirect calorimetry and heart rate in 14 subjects during rest and traditional videogaming using motion sensor and joystick controllers. Energy expenditure was higher while subjects were playing with the motion sensor (1.30±0.32 kcal/kg/hour) than with the joystick (1.07±0.26 kcal/kg/hour; Pvideogaming averaged 15.7 percent of predicted maximum for the motion sensor and 11.8 percent of maximum for the joystick. Minute ventilation was higher playing with the motion sensor (10.7±3.5 L/minute) than with the joystick (8.6±1.8 L/minute; Pvideogaming, rather than a result of exercise. We conclude that using a motion sensor with traditional videogames does not provide adequate energy expenditure to provide cardiovascular conditioning.

    Video-game use before bedtime has been linked with poor sleep outcomes for adolescents; however, experimental evidence to support this link is sparse. The present study investigated the capacity of presleep video-game playing to extend sleep latency and reduce subjective feelings of sleepiness in adolescents. The arousing psychophysiologic mechanisms involved and the impact of presleep video-game playing on sleep architecture were also explored. Thirteen male adolescent "evening types" (mean age = 16.6 years, SD = 1.1) participated in a counterbalanced, within-subjects design with experimental (active video gaming) and control (passive DVD watching) conditions. The experiment was conducted in the Flinders University Sleep Research Laboratory. Relative to the control condition, presleep video-game playing increased sleep-onset latency (Z= 2.45, p= .01) and reduced subjective sleepiness (Z = 2.36, p = .02)-but only slightly. Video gaming was related to changes in cognitive alertness (as measured by a power: p 0.05). Contrary to previous findings, sleep architecture was unaffected (both rapid eye movement and slow wave sleep: p > 0.05). Results suggest the direct effect of presleep video-game playing on adolescent sleep may be more modest than previously thought, suggesting that surveys linking stimulating presleep activities to poor sleep need substantiating with empirical evidence.

    Full Text Available Crop yield forecasting plays a vital role in coping with the challenges of the impacts of climate change on agriculture. Improvements in the timeliness and accuracy of yield forecasting by incorporating near real-time remote sensing data and the use of sophisticated statistical methods can improve our capacity to respond effectively to these challenges. The objectives of this study were (i to investigate the use of derived vegetation indices for the yield forecasting of spring wheat (Triticum aestivum L. from the Moderate resolution Imaging Spectroradiometer (MODIS at the ecodistrict scale across Western Canada with the Integrated Canadian Crop Yield Forecaster (ICCYF; and (ii to compare the ICCYF-model based forecasts and their accuracy across two spatial scales-the ecodistrict and Census Agricultural Region (CAR, namely in CAR with previously reported ICCYF weak performance. Ecodistricts are areas with distinct climate, soil, landscape and ecological aspects, whereas CARs are census-based/statistically-delineated areas. Agroclimate variables combined respectively with MODIS-NDVI and MODIS-EVI indices were used as inputs for the in-season yield forecasting of spring wheat during the 2000–2010 period. Regression models were built based on a procedure of a leave-one-year-out. The results showed that both agroclimate + MODIS-NDVI and agroclimate + MODIS-EVI performed equally well predicting spring wheat yield at the ECD scale. The mean absolute error percentages (MAPE of the models selected from both the two data sets ranged from 2% to 33% over the study period. The model efficiency index (MEI varied between −1.1 and 0.99 and −1.8 and 0.99, respectively for the agroclimate + MODIS-NDVI and agroclimate + MODIS-EVI data sets. Moreover, significant improvement in forecasting skill (with decreasing MAPE of 40% and 5 times increasing MEI, on average was obtained at the finer, ecodistrict spatial scale, compared to the coarser CAR scale.

    Active videogames (AVGs) may be useful for promoting physical activity for therapeutic uses, including for balance, rehabilitation, and management of illness or disease. The literature from 64 peer-reviewed publications that assessed health outcomes of AVGs for therapeutic purposes was synthesized. PubMed, Medline, and PyschInfo were queried for original studies related to the use of AVGs to improve physical outcomes in patients who were ill or undergoing rehabilitation related to balance, burn treatment, cancer, cerebral palsy, Down's syndrome, extremity dysfunction or amputation, hospitalization, lupus, Parkinson's disease, spinal injury, or stroke. The following inclusion criteria were used: (1) human subjects; (2) English language; (3) not duplicates; (4) new empirical data; and (5) tests an AVG, including commercially available or custom-designed. Studies were included regardless of participants' age or the study design. Overall, the vast majority of studies demonstrated promising results for improved health outcomes related to therapy, including significantly greater or comparable effects of AVG play versus usual care. However, many studies were pilot trials with small, homogeneous samples, and many studies lacked a control or comparison group. Some trials tested multiweek or multimonth interventions, although many used a single bout of gameplay, and few included follow-up assessments to test sustainability of improved health. AVGs were acceptable and enjoyable to the populations examined and appear as a promising tool for balance, rehabilitation, and illness management. Future research directions and implications for clinicians are discussed.

    Studies using conventional consoles have suggested a possible link between video-gaming and laparoscopic skill. The authors hypothesized that the Nintendo Wii, with its motion-sensing interface, would provide a better model for laparoscopic tasks. This study investigated the relationship between Nintendo Wii skill, prior gaming experience, and laparoscopic skill. In this study, 20 participants who had minimal experience with either laparoscopic surgery or Nintendo Wii performed three tasks on a Webcam-based laparoscopic simulator and were assessed on three games on the Wii. The participants completed a questionnaire assessing prior gaming experience. The score for each of the three Wii games correlated positively with the laparoscopic score (r = 0.78, 0.63, 0.77; P effect of prior gaming experience showed a significant positive correlation between the Wii score and the laparoscopic score (r = 0.713; P positively with the laparoscopic score (r = 0.578; P < 0.01), but no significant difference in the laparoscopic score was observed when the participants in the top tertile of experience were compared with those in the bottom tertile (P = 0.26). The study findings suggest a skill overlap between the Nintendo Wii and basic laparoscopic tasks. Surgical candidates with advanced Nintendo Wii ability may possess higher baseline laparoscopic ability.

  15. Making Games? Towards a theory of domestic videogaming

    Helen Thornham

    2008-01-01

    Full Text Available This article is concerned with the lived cultures or cultural practices of gaming - the where, when and with whom gaming occurs. It follows David Morley’s suggestion that we need to decentre the media from our analytical framework in order to grasp both the relations between new and ‘old’ media, as well the way we live with them. It is an argument taken literally in this article, where an alternative framework of ontological narrative is developed as the primary means through which an understanding of the relationships between gamers and technology is reached. It focuses on interviews with gaming households and is interested in the ways gamers actively narrate gaming experiences, their gaming selves, and the gaming technology. Using ontological narrative as a central signifier facilitates discussions of the relationship between technology and the social which go beyond what the technology ‘itself’ can offer. It also insists on a socio-political context for the discussion itself. Through a more ontological narrative approach, videogames are framed as agents in negotiations with the power dynamics of the house, but their agency is complicated through issues of performativity, pleasure and identity. Finally, this approach allows for a much more nuanced understanding of the way games and the meanings they hold for the gamers are enmeshed in the everyday.

    With the expanded genres of active videogames, one inevitably raises the question of whether it is worthwhile to use active videogames to promote physical activity if games involve violent themes. The purpose of the current study was to explore the effects of contextual cues of violence in an active videogame on (1) state hostility, (2) perceived arousal, (3) game enjoyment, (4) perceived effort in the game, and (5) activity intensity in the game. A one-factor between-subjects experiment with three conditions (minimal, moderate, and extreme contextual cues of violence) of playing an in-house-developed active videogame was conducted. Activity intensity was objectively measured using the ActiGraph (Pensacola, FL) model GT3X accelerometer. Psychological outcomes were measured using established scales. We did not find that the level of contextual cues of violence had any effect on the outcome variables, although the moderate level of contextual cues of violence resulted in a greater amount of feeling mean (P=0.011) and unsociable (P=0.038) among the players immediately after gameplay than players in the minimal contextual cues of violence condition. We did not find any statistically significant difference among the three conditions in terms of enjoyment, perceived arousal, or activity intensity. This study empirically examined the effects of contextual cues of violence in active videogames on player hostility, arousal, and enjoyment after gameplay as well as their physical activity intensity during gameplay. These findings provide some initial evidence to guide active videogame designers and researchers on how to design the games to be more engaging and thus elicit more activities among the players.

Aceh Province, Indonesia. A non-destructive method using allometric equations and landscape scale method were applied, where in carbon stocks at the points of samples are correlated with the index values of each transformation of the vegetation indexes; EVI and NDVI.  Results show that EVI values of study area from 0.05 to 0.90 and NDVI values from 0.17 to 0.85. The regression analysis between EVI with carbon stock value of sample locations equation is Y = 151.7X-39.76. with the coefficient of determination (R2 is 0.83. From this calculation, the total carbon stocks in the Production Forest area of Lembah Seulawah sub-district using EVI is estimated 790.344.41 tonnes, and the average value of carbon stocks in average is 51.48 tons per hectare.  Regression analysis between NDVI values at the research locations for the carbon stack measured samples is Y = 204.Xx-102.1 with coefficient of determination (R2 is 0.728. Total carbon stocks in production forest of Lembah Seulawah sub-district using NDVI is estimated 711.061.81 tones. and the average value of carbon stocks is 46.32 tons per hectare. From the above results it can be concluded that the vegetation indexes: EVI and NDVI are vegetation indexed that have a very close correlation with carbon stocks stands estimation. The correlation between EVI with carbon stock and the correlation between NDVI with carbon stock is not significantly different

    Monitoring forest phenology allows us to study the effects of climate change on vegetated land surfaces. Daily and composite time series (TS) of several vegetation indices (VIs) from MODerate resolution Imaging Spectroradiometer (MODIS) data have been widely used in scientific works for phenological studies since the beginning of the MODIS mission. The objective of this work was to use MODIS data to find the best VI/TS combination to estimate start-of-season (SOS) and end-of-season (EOS) dates across 50 temperate deciduous forests. Our research used as inputs 2001-2012 daily reflectance from MOD09GQ/MOD09GA products and 16-day composite VIs from the MOD13Q1 dataset. The 50 pixels centered on the 50 forest plots were extracted from the above-mentioned MODIS imagery; we then generated 5 different types of TS (1 daily from MOD09 and 4 composite from MOD13Q1) and used all of them to implement 6 VIs, obtaining 30 VI/TS combinations. SOS and EOS estimates were determined for each pixel/year and each VI/TS combination. SOS/EOS estimations were then validated against ground phenological observations. Results showed that, in our test areas, composite TS, if actual acquisition date is considered, performed mostly better than daily TS. EVI, WDRVI0.20 and NDVI were more suitable to SOS estimation, while WDRVI0.05 and EVI were more convenient in estimating early and advanced EOS, respectively.

    Planarians can regenerate a whole animal from only a small piece of their body, and have become an important model for stem cell biology. To identify regenerative processes dependent on Wnt growth factors in the planarian Schmidtea mediterranea (Smed), we analyzed RNAi phenotypes of Evi, a transmembrane protein specifically required for the secretion of Wnt ligands. We show that, during regeneration, Smed-evi loss-of-function prevents posterior identity, leading to two-headed planarians that resemble Smed-beta-catenin1 RNAi animals. In addition, we observe regeneration defects of the nervous system that are not found after Smed-beta-catenin1 RNAi. By systematic knockdown of all putative Smed Wnts in regenerating planarians, we identify Smed-WntP-1 and Smed-Wnt11-2 as the putative posterior organizers, and demonstrate that Smed-Wnt5 is a regulator of neuronal organization and growth. Thus, our study provides evidence that planarian Wnts are major regulators of regeneration, and that they signal through beta-catenin-dependent and -independent pathways.

    This experiment examined the effect of video-game violence on cooperative decision making. Participants (N= 48) were randomly assigned to play either a violent or a nonviolent version of the video game Doom in dyads. Following the video-game task, participants were separated and given an opportunity to choose to cooperate with their partner for mutual gain, withdraw from the interaction, or exploit their partner for their own benefit. Participants in the violent condition were significantly more likely to choose to exploit their partners than participants in the nonviolent condition. These findings suggest that playing violent video games may undermine prosocial motivation and promote exploitive behavior in social interactions.

    Full Text Available The objective of this study is to assess the effectiveness of videogames in comparison to simulations in a higher education environment and with regard to their attributes, motivation, and learning outcomes, as three of the main dimensions that play a role in the effectiveness of digital game-based learning. Results demonstrate significant differences between the attributes and motivation dimensions, while no significant differences were found for the learning outcomes. This would imply that although both instructional tools lead students to the desired level of knowledge acquisition, the motivation generated, together with the set of features provided by the games complement each other, leading to a superior learning experience. These results support the inclusion of videogames as a complement to simulations in higher education accounting and business environments and allow us to propose a blended approach that provides the learner with the ‘best of both worlds’.

    This article reviews research in the fields of psychology, literature, communication, human-computer interaction, public health, and consumer behavior on narrative and its potential relationships with videogames and story immersion. It also reviews a narrative's role in complementing behavioral change theories and the potential of story immersion for health promotion through videogames. Videogames have potential for health promotion and may be especially promising when attempting to reach youth. An understudied characteristic of videogames is that many contain a narrative, or story. Story immersion (transportation) is a mechanism through which a narrative influences players' cognition, affect, and, potentially, health behavior. Immersion promotes the suspension of disbelief and the reduction of counterarguments, enables the story experience as a personal experience, and creates the player's deep affection for narrative protagonists. Story immersion complements behavioral change theories, including the Theory of Planned Behavior, Social Cognitive Theory, and Self-Determination Theory. Systematic investigations are needed to realize the powerful potential of interactive narratives within theory-driven research.

    Full Text Available Movement therapy is one type of upper extremity intervention for children with cerebral palsy (CP to improve function. It requires high-intensity, repetitive and task-specific training. Tedium and lack of motivation are substantial barriers to completing the training. An approach to overcome these barriers is to couple the movement therapy with videogames. This investigation: (1 tested the feasibility of delivering a free Internet videogame upper extremity motor intervention to four children with CP (aged 8–17 years with mild to moderate limitations to upper limb function; and (2 determined the level of intrinsic motivation during the intervention. The intervention used free Internet videogames in conjunction with the Microsoft Kinect motion sensor and the Flexible Action and Articulated Skeleton Toolkit software (FAAST software. Results indicated that the intervention could be successfully delivered in the laboratory and the home, and pre- and post- impairment, function and performance assessments were possible. Results also indicated a high level of motivation among the participants. It was concluded that the use of inexpensive hardware and software in conjunction with free Internet videogames has the potential to be very motivating in helping to improve the upper extremity abilities of children with CP. Future work should include results from additional participants and from a control group in a randomized controlled trial to establish efficacy.

    Childhood obesity is a global epidemic. Health videogames are an emerging intervention strategy to combat childhood obesity. This systematic review examined published research on the effect of health videogames on childhood obesity. Fourteen articles examining 28 health videogames published between 2005 and 2013 in English were selected from 2433 articles identified through five major search engines. Results indicated that academic interest in using health videogames for childhood obesity prevention has increased during this time. Most games were commercially available. Most studies were of short duration. Diverse player and game play patterns have been identified. Most studies involved players of both genders with slightly more boys. The majority of players were non-white. Most studies had the players play the games at home, whereas some extended the play setting to school and sports/recreational facilities. Most of the games were commercially available. Positive outcomes related to obesity were observed in about 40 percent of the studies, all of which targeted overweight or obese participants.

    A growing body of evidence suggests that action videogames could enhance a variety of cognitive skills and more specifically attention skills. The aim of this study was to develop a novel adaptive videogame to support the rehabilitation of the most common consequences of traumatic brain injury (TBI), that is the impairment of attention and executive functions. TBI patients can be affected by psychomotor slowness and by difficulties in dealing with distraction, maintain a cognitive set for a long time, processing different simultaneously presented stimuli, and planning purposeful behavior. Accordingly, we designed a videogame that was specifically conceived to activate those functions. Playing involves visuospatial planning and selective attention, active maintenance of the cognitive set representing the goal, and error monitoring. Moreover, different game trials require to alternate between two tasks (i.e., task switching) or to perform the two tasks simultaneously (i.e., divided attention/dual-tasking). The videogame is controlled by a multidimensional adaptive algorithm that calibrates task difficulty on-line based on a model of user performance that is updated on a trial-by-trial basis. We report simulations of user performance designed to test the adaptive game as well as a validation study with healthy participants engaged in a training protocol. The results confirmed the involvement of the cognitive abilities that the game is supposed to enhance and suggested that training improved attentional control during play.

    2012-01-01

    Abstract We used qualitative methods to inform the development of an interactive videogame focused on behavior change to reduce risk and promote human immunodeficiency virus (HIV) prevention in young minority adolescents. Guided by community-partnered research principles, we conducted and analyzed 16 individual interviews and six focus groups with 10–15 year-old boys and girls (36 unique participants) at a neighborhood-based nonprofit organization serving youth from low-resource neighborhoods. Three recurrent themes lent themselves to translation into a videogame-based intervention. Adolescents reported protective factors and facilitators to engaging in risk behaviors, including (1) their personal ability to balance the tension between individuation and group membership, (2) the presence of stable mentor figures in their life, and (3) the neighborhood in which they live. We used these themes to inform the design of our videogame intervention with the goal that these methods may increase the intervention's efficacy at promoting HIV prevention by making them more tailored and relevant to a specific population. Our qualitative study provides a practical understanding of how important elements identified by minority youth regarding negotiating around risk behaviors can be integrated into a videogame intervention. These findings offer valuable insights to researchers whose goal is to design effective and tailored interventions to affect behavior change. PMID:24078897

    Videogame use is increasingly prevalent in people of all ages, and despite the wide amount of scientific evidence proving a role for electronic entertainment in human health, there is no evidence about the relation between use of videogames and sexual health. To investigate the association between use of videogames and male sexual health. We administered the two validated questionnaires, the Premature Ejaculation Diagnostic Tool (PEDT) and the International Index of Erectile Function (IIEF-15), to men 18 to 50 years old recruited through social networks and specific websites. In addition to the questionnaires, volunteers were asked to provide information on their gaming habit and lifestyle. An extended version of the IIEF-15 and PEDT, including data about gaming habits and relevant lifestyles. From June 18, 2014 through July 31, 2014, 599 men 18 to 50 years old completed the questionnaires. One hundred ninety-nine men reported no sexual activity during the previous 4 weeks; four records were rejected because of inherent errors. The remaining 396 questionnaires were analyzed, with 287 "gamers" (playing >1 hour/day on average) and 109 "non-gamers" providing all the required information. We found a lower prevalence of premature ejaculation in gamers compared with non-gamers (mean PEDT score = 3.57 ± 3.38 vs 4.52 ± 3.7, P videogame use and male sexual health. Compared with non-gamers, men playing videogames for more than 1 hour/day were less likely to have premature ejaculation but more likely to have decreased sexual desire. This is the first study aimed to assess male sexual health in gamers. We identified an association between PEDT and IIEF scores and videogame use; however, these findings require validation through interventional studies. Furthermore, volunteers were recruited through social networks, thus increasing the risk of recruitment bias. To our knowledge, this is the first observational study investigating the link between electronic entertainment and

    This article is a systematic review conducted of the research literature on digital videogames played by older adults and health outcomes associated with game play. Findings from each study meeting the inclusion criteria were analyzed and summarized into emergent themes to determine the impact of digital games in promoting healthy behaviors among older adults. A systematic review of the research literature was conducted through multiple academic databases for works, published between the years 2000 and 2011, looking at digital videogame interventions with adults 65 years of age and older. Multiple combinations of search terms and Boolean operators relevant to digital videogames and older adults were queried. A criteria matrix was created to code and evaluate studies. Thirteen studies met specific criteria for inclusion and were analyzed in the final review. Significant mental, physical, and social health factors, type of digital game platform, study design, and measurements are among emergent themes summarized from the reviewed research literature. Significant mental health outcomes of digital game interventions were found in the majority of the reviewed studies, followed by physical and lastly social health outcomes in older adults. A majority of the studies revealed significant positive effects on health outcomes associated with digital videogame play among older adults. With current advancements in technology, including advanced motion sensing, digital game platforms have significant potential for positive health impact among older populations. More robust and rigorous research designs are needed to increase validity and reliability of results and establish stronger causal relationships on the health benefits of digital videogame play for older adults.

    Abstract Objectives: Adults with schizophrenia are a growing segment of the older adult population. Evidence suggests that they engage in limited physical activity. Interventions are needed that are tailored around their unique limitations. An active videogame-based physical activity program that can be offered at a treatment facility can overcome these barriers and increase motivation to engage in physical activity. The purpose of this report is to describe the adherence to a videogame-based physical activity program using the Kinect® for Xbox® 360 game system (Microsoft®, Redmond, WA) in older adults with schizophrenia. Materials and Methods: This was a descriptive longitudinal study among 34 older adults with schizophrenia to establish the adherence to an active videogame-based physical activity program. In our ongoing program, once a week for 6 weeks, participants played an active videogame, using the Kinect for Xbox 360 game system, for 30 minutes. Adherence was measured with a count of sessions attended and with the total minutes attended out of the possible total minutes of attendance (180 minutes). Results: Thirty-four adults with schizophrenia enrolled in the study. The mean number of groups attended was five out of six total (standard deviation=2), and the mean total minutes attended were 139 out of 180 possible (standard deviation=55). Fifty percent had perfect attendance. Conclusions: Older adults with schizophrenia need effective physical activity programs. Adherence to our program suggests that videogames that use the Kinect for Xbox 360 game system are an innovative way to make physical activity accessible to this population. PMID:26192371

    Serious video-games are innovative tools used to train the motor skills of subjects affected by neurological disorders. They are often developed to train a specific type of patients and the rules of the game are standardly defined. A system that allows the therapist to design highly patient-oriented video-games, without specific informatics skills, is proposed. The system consists of one personal computer, two screens, a Kinect™ sensor and a specific software developed here for the design of the video-games. It was tested with the collaboration of three therapists and six patients, and two questionnaires were filled in by each patient to evaluate the appreciation of the rehabilitative sessions. The therapists learned easily how to use the system, and no serious difficulties were encountered by the patients. The questionnaires showed an overall good satisfaction by the patients and highlighted the key-role of the therapist in involving the patients during the rehabilitative session. It was found that the proposed system is effective for developing patient-oriented video-games for rehabilitation. The two main advantages are that the therapist is allowed to (i) develop personalized video-games without informatics skills and (ii) adapt the game settings to patients affected by different pathologies. Implications for rehabilitation Virtual reality and serious video games offer the opportunity to transform the traditional therapy into a more pleasant experience, allowing patients to train their motor and cognitive skills. Both the therapists and the patients should be involved in the development of rehabilitative solutions to be highly patient-oriented. A system for the design of rehabilitative games by the therapist is described and the feedback of three therapists and six patients is reported.

    The ability to inventory and map soil salinity at regional scales remains a significant challenge to scientists concerned with the salinization of agricultural soils throughout the world. Previous attempts to use satellite or aerial imagery to assess soil salinity have found limited success in part because of the inability of methods to isolate the effects of soil salinity on vegetative growth from other factors. This study evaluated the use of Moderate Resolution Imaging Spectroradiometer (MODIS) imagery in conjunction with directed soil sampling to assess and map soil salinity at a regional scale (i.e., 10-10(5) km(2)) in a parsimonious manner. Correlations with three soil salinity ground truth datasets differing in scale were made in Kittson County within the Red River Valley (RRV) of North Dakota and Minnesota, an area where soil salinity assessment is a top priority for the Natural Resource Conservation Service (NRCS). Multi-year MODIS imagery was used to mitigate the influence of temporally dynamic factors such as weather, pests, disease, and management influences. The average of the MODIS enhanced vegetation index (EVI) for a 7-yr period exhibited a strong relationship with soil salinity in all three datasets, and outperformed the normalized difference vegetation index (NDVI). One-third to one-half of the spatial variability in soil salinity could be captured by measuring average MODIS EVI and whether the land qualified for the Conservation Reserve Program (a USDA program that sets aside marginally productive land based on conservation principles). The approach has the practical simplicity to allow broad application in areas where limited resources are available for salinity assessment.

    This study examines the effects of exposure to online videogame violence on Chinese adolescents' attitudes toward violence, empathy, and aggressive behavior. Results of bivariate analyses show that playing violent videogames on the Internet was associated with greater tolerance of violence, a lower emphatic attitude, and more aggressive behavior. Results of hierarchical regression analyses showed sustained relationships between exposure and pro-violent attitudes and empathy when exposure was examined simultaneously with gender, computer use, and Internet use. However, the linkage between exposure and aggression became non-significant, suggesting that the effects of playing violent videogames were greater for attitudinal outcomes than on overt behavior. Gender differences in playing videogames and in effects were also found.

    The most productive methods of recruitment for a videogame for health (G4H) trial are not known. Success or failure of recruitment methods has been reported for a variety of clinical trials, but few specifically for G4H trials. This study's goal was to recruit 444 overweight or obese (body mass index percentile between the 84.5th-99.4th percentiles) children between the ages of 10-12 years. The article reports the results of different methods of participant recruitment. Participants had to agree to three fasting blood samples (baseline, immediately after, and 2 months later); be willing to wear an accelerometer for 7 days at each assessment; read and speak English fluently (because the games were in English); have no history of any condition that would affect what he/she could eat or how much physical activity he/she could get; and have an eligible home computer purchased in the last 5 years with high-speed internet. Hardware criteria reflected the types of computers upon which Diab-Nano could be effectively played. Recruitment was conducted over a 35-month period and included electronic media, print advertising, community recruitment, and an internal volunteer list. Respondents were guided to a web-based screening questionnaire that asked for source of hearing about the study. Although diverse recruitment methods were used, slow recruitment resulted in obtaining only 45% of the recruitment goal (n = 199). Electronic media (e.g., radio, television, and internet), which reached millions of targeted parents, resulted in only 76 respondents, of whom 13 became participants; print media (e.g., magazine, newsletter/newspaper, and mail), which also reached large numbers of parents, resulted in 192 respondents, of whom 19 became participants; community recruitment (e.g., school, friend or family, doctors office, flyer, work, community program) resulted in 162 respondents, of whom 38 became participants; and the internal volunteer list resulted in 413 respondents, of

    Reports of videogame-related illness and injury soon emerged in the literature with the inception of videogame systems and subsequent development of novel gaming platforms and technologies. In an effort to better detail the impacts of these phenomena and provide recommendations for injury prevention as it relates to Pokémon Go and the larger world of augmented reality games, we conducted an extensive systems-based review of past trends in videogame-related illness and injury from the literature. A literature review using PubMed, Medline, and PsycInfo databases with search terms "Pokémon GO," "videogame injuries," "augmented reality injuries," and "Nintendo Injury" was performed. The search was limited to the English language, and the Boolean were used to combine the search terms. The literature search yielded 359 peer-reviewed articles, 44 of which met the study criteria and included in the review. Seventeen additional popular press reports detailing injuries related to Pokémon Go were also incorporated. Videogame-related injuries and illness include both physical trauma as well as psychological and behavioral disorder with unique patterns of injury and illness linked to specific gaming platforms. As videogames become increasingly advanced and immersive, they expose players to unique and often more serious injury and illness. Augmented reality games, such as Pokémon GO, are the next step in the evolution of this trend and likely portend a future in which many pathologic processes may become increasingly common.

    Full Text Available UNLABELLED: Abnormal visual experience during a sensitive period of development disrupts neuronal circuitry in the visual cortex and results in abnormal spatial vision or amblyopia. Here we examined whether playing video games can induce plasticity in the visual system of adults with amblyopia. Specifically 20 adults with amblyopia (age 15-61 y; visual acuity: 20/25-20/480, with no manifest ocular disease or nystagmus were recruited and allocated into three intervention groups: action videogame group (n = 10, non-action videogame group (n = 3, and crossover control group (n = 7. Our experiments show that playing video games (both action and non-action games for a short period of time (40-80 h, 2 h/d using the amblyopic eye results in a substantial improvement in a wide range of fundamental visual functions, from low-level to high-level, including visual acuity (33%, positional acuity (16%, spatial attention (37%, and stereopsis (54%. Using a cross-over experimental design (first 20 h: occlusion therapy, and the next 40 h: videogame therapy, we can conclude that the improvement cannot be explained simply by eye patching alone. We quantified the limits and the time course of visual plasticity induced by video-game experience. The recovery in visual acuity that we observed is at least 5-fold faster than would be expected from occlusion therapy in childhood amblyopia. We used positional noise and modelling to reveal the neural mechanisms underlying the visual improvements in terms of decreased spatial distortion (7% and increased processing efficiency (33%. Our study had several limitations: small sample size, lack of randomization, and differences in numbers between groups. A large-scale randomized clinical study is needed to confirm the therapeutic value of video-game treatment in clinical situations. Nonetheless, taken as a pilot study, this work suggests that video-game play may provide important principles for treating amblyopia

    Full Text Available We have chosen this topic for research as we consider it a transcendental problem in the lives of children today, considering the importance which television now has toward childhood behavior and the increase of programming in new channels and the widespread use of videogames. Nowadays television hasn`t got sufficiently stipulated timetables; therefore children frequently watch violent scenes which are inappropriate for their age, with the added danger that they may want to imitate those scenes which cause the greatest impact in them and which can even cause them harm. We are including a recent research project (1999 on the influence of television and videogames in the conduct of children, as well as brief history of the principal authors who have studied this topic, the evolution of which has brought about notable changes and educational consequences.

    Full Text Available A high percentage of video-games now in the market have contents related with physical and psychological violence. There are investigations that show that this kind of games is mainly used by children and adolescents. This fact reinitiates the polemic of the possible influence in the formation of their personality and, very specially, in the construction of the value scale that will direct their present and future behaviour as citizens. This paper shows the partial results of a recent research in which adult players related with the education area (future teachers analyzed critically the axiological component of a very important group of video-games which are important in the sales lists. For that purpose, a very specific scale has been used, with indicators related to the argument, the initial and final videos, the protagonist’s behaviour, the stenography, clothes, actions and partial and final results obtained by players.

    Few studies have examined exercise as a substance use disorder treatment. This pilot study investigated the feasibility and acceptability of an exercise intervention comprising the Wii Fit Plus™ and of a time-and-attention sedentary control comprising Wii™ videogames. We also explored their impact on physical activity levels, substance use, and psychological wellness. Twenty-nine methadone-maintained patients enrolled in an 8-week trial were randomly assigned to either Active Game Play (Wii Fit Plus™ videogames involving physical exertion) or Sedentary Game Play (Wii™ videogames played while sitting). Participants had high satisfaction and study completion rates. Active Game Play participants reported greater physical activity outside the intervention than Sedentary Game Play participants despite no such differences at baseline. Substance use decreased and stress and optimism improved in both conditions. Active Game Play is a feasible and acceptable exercise intervention, and Sedentary Game Play is a promising time-and-attention control. Further investigations of these interventions are warranted.

    Pediatric oncology patients often experience fatigue and physical and mental deconditioning during and following chemotherapy treatments, contributing to diminished quality of life. Patient empowerment is a core principle of patient-centered care and reflects one's ability to positively affect his or her own health behavior and health status. Empowerment interventions may enhance patients' internal locus of control, resilience, coping skills, and self-management of symptoms related to disease and therapy. Clinical and technological advancements in therapeutic videogames and mobile medical applications (mobile health) can facilitate delivery of the empowerment interventions for medical purposes. This review summarizes clinical strategies for empowering pediatric cancer patients, as well as their relationship with developing a "fighting spirit" in physical and mental health. To better understand physiological aspects of empowerment and to elucidate videogame-based intervention strategies, brain neuronal circuits and neurotransmitters during stress, fear, and resilience are also discussed. Neuroimaging studies point to the role of the reward system pathways in resilience and empowerment in patients. Taken together, videogames and mobile health applications open translational research opportunities to develop and deliver empowerment interventions to pediatric cancer patients and also to those with other chronic diseases.

    Researchers have studied whether some youth are "addicted" to video games, but previous studies have been based on regional convenience samples. Using a national sample, this study gathered information about video-gaming habits and parental involvement in gaming, to determine the percentage of youth who meet clinical-style criteria for pathological gaming. A Harris poll surveyed a randomly selected sample of 1,178 American youth ages 8 to 18. About 8% of video-game players in this sample exhibited pathological patterns of play. Several indicators documented convergent and divergent validity of the results: Pathological gamers spent twice as much time playing as nonpathological gamers and received poorer grades in school; pathological gaming also showed comorbidity with attention problems. Pathological status significantly predicted poorer school performance even after controlling for sex, age, and weekly amount of video-game play. These results confirm that pathological gaming can be measured reliably, that the construct demonstrates validity, and that it is not simply isomorphic with a high amount of play.

    The purpose of this research is to explore the capacity of story to connect to a health-related videogame, as well as the qualities that may increase efficacy by making the story compelling. Parents of 3-5-year-old children often report difficulty getting their children to eat vegetables, which are protective against chronic illnesses. Videogames may be vehicles for training parenting practices for successful vegetable consumption outcomes but often rely on stories to provide context and details. Unfortunately, storytelling may interrupt immersion and player agency. Delivering stories outside of gameplay may provide an understanding of game situations while maintaining immersion. Two companion storylines (one a romantic adventure and the other a suspenseful fantasy) were generated for a vegetable parenting game, "Mommio," targeting mothers of preschool children. Mothers of 3-5-year-old children (n=18) read both storylines and completed semistructured interviews. Mothers preferred the romantic adventure, which featured strong characters, relatable issues, and an engaging plot. Most mothers were interested in playing the "Mommio" videogame after reading the stories. Results suggest that it is possible for prose literature to both motivate gameplay and be an immersive narrative companion to, but separate from, games for health. This literature should include engaging, realistic stories and relatable strong characters.

    To compare the prevalence of television (TV) watching and of computer/videogame use among high school students (15-19 years) from Southern Brazil between 2001 and 2011 and to identify associated socio-demographic factors. Panel studies were conducted with high school students in the state of Santa Catarina, Brazil, in 2001 (n = 5,028) and 2011 (n = 6,529). TV watching and computer/videogame use were collected using questionnaires. Prevalence of ≥2 h/day of TV watching dropped from 76.8 to 61.5 % and ≥2 h/day of computer/videogame use increased from 37.9 to 60.6 %. In both surveys, those aged 15-16 and those who did not work had higher likelihoods of being exposed to ≥2 h/day of TV watching. Boys, those with higher family income, and those who were living in urban areas had higher likelihoods of ≥2 h/day of computer/videogame use. Older age, studying at night and not working were protective factors to these behaviors. After a decade, there was a decrease in the prevalence of TV viewing and an increase in computer/videogame use. Socio-demographic factors were differently associated with these behaviors.

    Interest in health videogames to stimulate health behavior change is increasing, yet little research exists on their use. This study tested the acceptability of an online health videogame called "Fitter Critters™" (Megazoid Games, Collegeville, PA) for improving healthy diet and activity in elementary school students. In October and November 2011, fifth grade students ( n =97) from a school in central Massachusetts played the game for 1 week during their health class. Measures of nutrition and activity knowledge, attitudes, and self-efficacy were completed prior to playing the game and again on the final day along with a videogame acceptability questionnaire. The videogame was highly acceptable to participants as measured by the acceptability questionnaire mean rating of 4.52 (SD=0.60), where 1=strongly disagree and 5=strongly agree; 73% of students played the game at least once outside of class. Significant increases in positive attitudes toward healthy eating ( P <0.001) and healthy eating self-efficacy ( P =0.02) and marginally significant increases in nutrition knowledge ( P =0.08) were observed. The "Fitter Critters" health videogame engages students in learning about healthy eating and activity. Further research should assess whether the positive changes observed in knowledge, attitudes, and self-efficacy translate into behavior change.

    To evaluate the prognostic value of ecotropic viral integration 1 gene (EVI1) overexpression in acute myeloid leukemia (AML) with MLL gene rearrangements. We identified 286 patients with AML with t(11q23) enrolled onto German-Austrian Acute Myeloid Leukemia Study Group and Dutch-Belgian-Swiss Hemato-Oncology Cooperative Group prospective treatment trials. Material was available from 177 AML patients for EVI1 expression analysis. We divided 286 MLL-rearranged AMLs into three subgroups: t(9;11)(p22;q23) (44.8%), t(6;11)(q27;q23) (14.7%), and t(v;11q23) (40.5%). EVI1 overexpression (EVI1(+)) was found in 45.8% of all patients with t(11q23), with t(6;11) showing the highest frequency (83.9%), followed by t(9;11) at 40.0%, and t(v;11q23) at 34.8%. Concurrent gene mutations were rare or absent in all three subgroups. Within all t(11q23) AMLs, EVI1(+) was the sole prognostic factor, predicting for inferior overall survival (OS; hazard ratio [HR], 2.06; P = .003), relapse-free survival (HR, 2.28; P = .002), and event-free survival (HR, 1.79; P = .009). EVI1(+) AMLs with t(11q23) in first complete remission (CR) had a significantly better outcome after allogeneic transplantation compared with other consolidation therapies (5-year OS, 54.7% v 0%; Mantel-Byar, P = .0006). EVI1(-) t(9;11) AMLs had lower WBC counts, more commonly FAB M5 morphology, and frequently had additional trisomy 8 (39.6%; P < .001). Among t(9;11) AMLs, EVI1(+) again was the sole independent adverse prognostic factor for survival. Deregulated EVI1 expression defines poor prognostic subsets among AML with t(11q23) and AML with t(9;11)(p22;q23). Patients with EVI1(+) MLL-rearranged AML seem to benefit from allogeneic transplantation in first CR.

    Currently there is a lack of knowledge on spatio-temporal patterns of land surface dynamics at medium spatial scale in southern Africa, even though this information is essential for better understanding of ecosystem response to climatic variability and human-induced land transformations. In this study, we analysed vegetation dynamics across a large area in southern Africa using the 14-years (2000-2013) of medium spatial resolution (250 m) MODIS-EVI time-series data. Specifically, we investigated temporal changes in the time series of key phenometrics including overall greenness, peak and timing of annual greenness over the monitoring period and study region. In order to specifically capture spatial and per pixel vegetation changes over time, we calculated trends in these phenometrics using a robust trend analysis method. The results showed that interannual vegetation dynamics followed precipitation patterns with clearly differentiated seasonality. The earliest peak greenness during 2000-2013 occurred at the end of January in the year 2000 and the latest peak greenness was observed at the mid of March in 2012. Specifically spatial patterns of long-term vegetation trends allowed mapping areas of (i) decrease or increase in overall greenness, (ii) decrease or increase of peak greenness, and (iii) shifts in timing of occurrence of peak greenness over the 14-year monitoring period. The observed vegetation decline in the study area was mainly attributed to human-induced factors. The obtained information is useful to guide selection of field sites for detailed vegetation studies and land rehabilitation interventions and serve as an input for a range of land surface models.

    Environmental enrichment plans for captive nonhuman primates often include provision of foraging devices. The rationale for using foraging devices is to promote species-typical activity patterns that encourage physical engagement and provide multi-sensory stimulation. However, these devices have been shown to be ineffective at sustaining manipulation over long periods of time, and often produce minimal cognitive engagement. Here we use an evidence-based approach to directly compare the amount of object-directed behavior with a foraging device and a computer-based videogame system. We recorded 11adult male rhesus monkeys’ interactions with a foraging device and two tasks within a joystick videogame cognitive test battery. Both techniques successfully produced high levels of engagement during the initial 20-min of observation. After 1-hr the monkeys manipulated the foraging device significantly less than the joystick, F(2,10)= 43.93, p videogame play for the majority of a 5-hr period, provided that they received a 94mg chow pellet upon successful completion of trials. Using a model approach we developed previously as a basis for standardized cost:benefit analysis to inform facility decisions, we calculated the comprehensive cost of incorporating a videogame system as an enrichment strategy.

    Two recent systematic reviews have surveyed the existing evidence for the effectiveness of active videogames in children/adolescents and in elderly people. In the present study, effect sizes were added to these systematic reviews, and meta-analyses were performed. All reviewed studies were considered for inclusion in the meta-analyses, but only studies were included that investigated the effectiveness of active videogames, used an experimental design, and used actual health outcomes as the outcome measures (body mass index for children/adolescents [k=5] and functional balance for the elderly [k=6]). The average effect of active videogames in children and adolescents was small and nonsignificant: Hedges' g=0.20 (95 percent confidence interval, -0.08 to 0.48). Limited heterogeneity was observed, and no moderator analyses were performed. For the effect of active videogames on functional balance in the elderly, the analyses revealed a medium-sized and significant effect of g=0.68 (95 percent confidence interval, 0.13-1.24). For the elderly studies, substantial heterogeneity was observed. Moderator analyses showed that there were no significant effects of using a no-treatment control group versus an alternative treatment control group or of using games that were especially created for health-promotion purposes versus off-the-shelf games. Also, intervention duration and frequency, sample size, study quality, and dropout did not significantly moderate the effect of active videogames. The results of these meta-analyses provide preliminary evidence that active videogames can have positive effects on relevant outcome measures in children/adolescents and elderly individuals.

    Environmental enrichment plans for captive nonhuman primates often include provision of foraging devices. The rationale for using foraging devices is to promote species-typical activity patterns that encourage physical engagement and provide multi-sensory stimulation. However, these devices have been shown to be ineffective at sustaining manipulation over long periods of time, and often produce minimal cognitive engagement. Here we use an evidence-based approach to directly compare the amount of object-directed behavior with a foraging device and a computer-based videogame system. We recorded 11 adult male rhesus monkeys' interactions with a foraging device and two tasks within a joystick videogame cognitive test battery. Both techniques successfully produced high levels of engagement during the initial 20 min of observation. After 1 hr the monkeys manipulated the foraging device significantly less than the joystick, F(2,10) = 43.93, P videogame play for the majority of a 5 hr period, provided that they received a 94 mg chow pellet upon successful completion of trials. Using a model approach, we developed previously as a basis for standardized cost:benefit analysis to inform facility decisions, we calculated the comprehensive cost of incorporating a videogame system as an enrichment strategy. The videogame system has a higher initial cost compared to widely-used foraging devices, however, the ongoing labor and supply costs are relatively low. Our findings add to two decades of empirical studies by a number of laboratories that have demonstrated the successful use of videogame-based systems to promote sustained non-social cognitive engagement for macaques.

    Increased prevalence and penetration of cellphone and mobile Internet use have raised significant concerns about children's health and safety by offering new spaces for cyberbullying, harassment, and sexual misconduct. "Cyberhero Mobile Safety" is a videogame-based education program designed using tenets of the capacity model with the goal of instilling the knowledge and skills necessary to safely and productively navigate the mobile online environment. This study evaluates its usability, appeal, and perceived impact and usefulness. Six educational videogames were part of a program delivered to 3rd-6th grade students (n=108) across six public schools in Upstate New York. Videogame play was electronically captured to evaluate usability. Likeability, acceptability, and perceived usefulness of videogame content were evaluated through postgame questionnaires. Videogame usability criteria were achieved on 82.7 percent of the students' gameplays. On a scale from 1 (low) to 5 (high), mean ratings were 4.09 (standard deviation [SD]=1.28) for likeability, 3.54 (SD=1.61) for acceptability, and 4.16 (SD=1.33) for perceived message usefulness. The "Cyberhero Mobile Safety" program is a feasible and potentially effective platform for delivering information about safe and healthy cellphone and Internet use to children. Results support the use of the capacity model to design educational videogames because games that aligned with theory principles were reported as having the most impact and being the most useful at shifting children's online behaviors. Future research should directly test the individual components of the capacity model to inform educational game design.

  1. Using Videogame Apps to Assess Gains in Adolescents’ Substance Use Knowledge: New Opportunities for Evaluating Intervention Exposure and Content Mastery

    2015-01-01

    Background Videogame interventions are becoming increasingly popular as a means to engage people in behavioral interventions; however, strategies for examining data from such interventions have not been developed. Objective The objective of this study was to describe how a technology-based intervention can yield meaningful, objective evidence of intervention exposure within a behavioral intervention. This study demonstrates the analysis of automatic log files, created by software from a videogame intervention, that catalog game play and, as proof of concept, the association of these data with changes in substance use knowledge as documented with standardized assessments. Methods We analyzed 3- and 6-month follow-up data from 166 participants enrolled in a randomized controlled trial evaluating a videogame intervention, PlayForward: Elm City Stories (PlayForward). PlayForward is a videogame developed as a risk reduction and prevention program targeting HIV risk behaviors (substance use and sex) in young minority adolescents. Log files were analyzed to extract the total amount of time spent playing the videogame intervention and the total number of game levels completed and beaten by each player. Results Completing and beating more of the game levels, and not total game play time, was related to higher substance use knowledge scores at the 3- (P=.001) and 6-month (P=.001) follow-ups. Conclusions Our findings highlight the potential contributions a videogame intervention can make to the study of health behavior change. Specifically, the use of objective data collected during game play can address challenges in traditional human-delivered behavioral interventions.

    Although the prevalence of adolescent smoking has declined over the past two decades, the rate of decline has slowed. Electronic videogames show promise as an effective tool for health behavior change; however, the current state of tobacco prevention and cessation games has not been previously reviewed or evaluated. Currently available tobacco-related videogames were identified through online searches and in smartphone application stores. In total, 88 games were systematically coded for characteristics, content, and quality using a reliable and valid coding instrument developed for this research. The majority of games included at least two components of interactivity (75.0 percent) and at least one mechanism for rewarding (69.3 percent). However, most games lacked a story line (97.7 percent) and components for sense of control (25.0 percent). There were an average of 3.54 (standard deviation = 2.20) theoretical constructs in the games, with attitudes (83.0 percent), knowledge (78.4 percent), and perceived severity (55.7 percent) being the most common. The most common educational approach used was the affective education model (83.0 percent). Most games included at least one tobacco message (90.9 percent), with a majority of messages being loss-framed (63.6 percent) and/or one-sided (75.0 percent). Although today's anti-tobacco videogames contain many effective features, numerous qualities and best practices for changing behaviors through games are not present. Future games should seek to address these best practices in their development and evaluation to increase the likelihood they will be effective.

    New active videogames (AVGs) may provide youth an alternative to traditional play. The purpose of this study was to compare the physical activity energy expenditure (PAEE), intensity, and enjoyment of AVGs with those of seated videogames (SVGs). Youth (8-17 years old) volunteered to play a random selection of six (two SVGs, four AVGs) videogames for 6-10 minutes each. Prior to participation, height, weight, and resting metabolic rate (RMR) were measured. A portable metabolic analyzer was worn during the games to measure total energy expenditure, and PAEE was calculated as (total energy expenditure - measured RMR). An accelerometer was worn on the right hip to measure intensity in counts/minute and steps/minute. Youth were classified as child (8-12 years old) versus teen (13-17 years old), healthy weight (body mass index [BMI] <85th percentile) versus overweight (BMI ≥85th percentile), and male versus female. A three-way mixed-model analysis of variance was used to compare differences in PAEE (metabolic equivalents [METs] and kcal/minute) with sex, weight status, and age group as main effects, including Bonferroni's adjustment. Most AVGs were moderate to vigorous intensity (4.6±0.1 METs; range, 2.8-6.6 METs), where steps/minute (lower-body movement) was positively related to PAEE (R(2)=0.68). All SVGs were classified as light intensity (1.7±0.0 METs). PAEE (kcal/minute) was significantly higher during AVGs and for teens, males, and overweight youth. There was no significant difference in enjoyment between AVGs and SVGs. AVGs elicited sufficient energy cost to be a suitable alternative for traditional play and may contribute to the recommended dose of physical activity, particularly in teens, males, and overweight youth.

    Abstract Objectives Standing and gait balance problems are common in children with cerebral palsy (CP), resulting in falls and injuries. Task-oriented exercises to strengthen and stretch muscles that shift the center of mass and change the base of support are effective in improving balance. Gaming environments can be challenging and fun, encouraging children to engage in exercises at home. The aims of this project were to demonstrate the technical feasibility, ease of use, appeal, and safety of a computer-based videogame program designed to improve balance in children with CP. Materials and Methods This study represents a close collaboration between computer design and clinical team members. The first two phases were performed in the laboratory, and the final phase was done in subjects' homes. The prototype balance game was developed using computer-based real-time three-dimensional programming that enabled the team to capture engineering data necessary to tune the system. Videogame modifications, including identifying compensatory movements, were made in an iterative fashion based on feedback from subjects and observations of clinical and software team members. Results Subjects (n=14) scored the game 21.5 out of 30 for ease of use and appeal, 4.0 out of 5 for enjoyment, and 3.5 on comprehension. There were no safety issues, and the games performed without technical flaws in final testing. Conclusions A computer-based videogame incorporating therapeutic movements to improve gait and balance in children with CP was appealing and feasible for home use. A follow-up study examining its effectiveness in improving balance in children with CP is recommended. PMID:24761324

    Delmas, Guylain; Champagnat, Ronan; Augeraud, Michel

    Adding narrative in computer game is complicated because it may restrict player interactivity. Our aim is to design a controller that dynamically built a plot, through the game execution, centred on player's actions. Tabletop Role-playing games manage to deal with this goal. This paper presents a study of role-playing games, their organization, and the models commonly used for narrative generation. It then deduces a proposition of components and data structures for interactive storytelling in videogames. A prototype of a social game has been developed as example.

    New types of controllers allow a player to make inputs to a video game or simulation by moving the entire controller itself or by gesturing or by moving the player's body in whole or in part. This capability is typically accomplished using a wireless input device having accelerometers, gyroscopes, and a camera. The present invention exploits these wireless motion-sensing technologies to modulate the player's movement inputs to the videogame based upon physiological signals. Such biofeedback-modulated video games train valuable mental skills beyond eye-hand coordination. These psychophysiological training technologies enhance personal improvement, not just the diversion, of the user.

    Video-game playing is associated with an increased obesity risk. The association of video-game playing with body composition, physical activity and eating behaviour was investigated. A total of 45 young males (age range 18-27 years, BMI range 18.5-35.1 kg/m(2)) were recruited. Measurements of body composition and blood pressure were performed. The EPIC-FFQ questionnaire was used to assess dietary intake. A questionnaire battery was administered to assess physical activity, eating behaviour, sleep quality and frequency of video-game playing (hours/week). Subjects were categorised into frequent (>7 h/week) and non-frequent (≤7 h/week) players. Frequent video-game players had greater waist circumference and fat mass. Video-game playing was significantly associated with high added sugar and low fibre consumption. A higher level of dietary restraint was observed in non-frequent video-game users. These preliminary results identify frequent video-game playing as an important lifestyle behaviour which may have important implications for understanding obesity risk in young male adults.

  10. Determining Stochasticity and Causality of Vegetation Dynamics in the Southwestern Amazon: Non-linear Time Series Analysis and Dynamic Factor Analysis of EVI2 Data

    Infrastructure projects such as road paving have proven to bring a variety of (mainly) socio-economic advantages to countries and populations. However, many studies have also highlighted the negative socio-economic and biophysical effects that these developments have at local, regional and even larger scales. The "MAP" area (Madre de Dios in Peru, Acre in Brazil, and Pando in Bolivia) is a biodiversity hotspot in the southwestern Amazon where sections of South America's Inter-Oceanic Highway were paved between 2006 and 2010. We are interested in vegetation dynamics in the area since it plays an important role in ecosystem functions and ecosystem services in socio-ecological systems: it provides information on productivity and structure of the forest. In preparation of more complex and mechanistic simulation of vegetation, non-linear time series analysis and Dynamic Factor Analysis (DFA) was conducted on Enhanced Vegetation Index (EVI) time series - which is a remote sensing product and provides information on vegetation dynamics as it detects chlorophyll (productivity) and structural change. Time series of 30 years for EVI2 (from MODIS and AVHRR) were obtained for 100 communities in the area. Through specific time series cluster analysis of the vegetation data, communities were clustered to facilitate data analysis and pattern recognition. The clustering is spatially consistent, and appears to be driven by median road paving progress - which is different for each cluster. Non-linear time series analysis (multivariate singular spectrum analysis, MSSA) separates common signals (or low-dimensional attractors) across clusters. Despite the presence of this deterministic structure though, time series behavior is mostly stochastic. Granger causality analysis between EVI2 and possible response variables indicates which variables (and with what lags) are to be included in DFA, resulting in unique Dynamic Factor Models for each cluster.

    The use of videogames in healthcare interventions is gaining popularity, but there is still a gap in the understanding on how these types of interventions are used for the management of diabetes. The purpose of this review is to examine published research on the use of videogames for diabetes management. With the increased use of mobile technology, the review was expanded to understand whether games, gamification, and virtual environments can be used for diabetes self-management. Out of the 307 articles identified, only 10 articles met the inclusion criteria of the study. The duration of most studies was short, with small sample sizes. All interventions targeted behavioral changes examining risk reduction of diabetes-related risk and promotion of healthy behavior among study participants. Videogames appeared to be helpful tools for education in some interventions, whereas gamification and virtual environments increased extrinsic motivation and provided positive reinforcement. This review concludes by discussing the potential of using videogames and gamification for the self-management of diabetes.

    Full Text Available Objectives: Balance disorder is one of the most common problems after stroke causes falling and fear of falling in some patients. The balance based video games are newly used in people with motor problems. It is very important to use different interventions for balance issues. The aim of this study is to determine the effectiveness of videogame on balance and fear of falling in one participant. Methods: This experimental study was done in a single subject system, A-B design for one patient with chronic stroke. This method including repetitive measures conducted in two phases, baseline and then twelve intervention sessions. Berg Balance Scale, Timed up and go, Functional Reach, the maximum weight bearing in different directions and the deviation from center were conducted for balance assessing. Fear of falling questionnaire was used to assess fear of falling. Analysis of results was done by C-statistic, Bayesian factor, Mann Whitney U, and visual analysis graphs. Results: The results showed significant improvement for balance skills, the maximum force produced by lower extremities and reducing fear of falling parameters. But the deviation from center graphs did not showed distinct pattern. Discussion: All analysis confirmed the efficacy of videogames on balance skills and fear of falling improvement. However, the deviation from center did not show improvement and it seems to need more studies.

    2012-01-01

    Educational videogames can be designed to provide instructional feedback responsive to specific actions. However, existing research indicates that students tend to ignore the feedback provided. That is, students often use ineffective help-seeking strategies. Research on the topic of help-seeking in learning environments have primarily focused on the role of cognitive factors, the nature of the help, or issues of timing and frequency. There is a noticeable gap in understanding how to motivate the use provided feedback. This study examined the relation between incentivizing the use of feedback and providing an explanation of the game's scoring rules on math learning in a pre-algebra videogame. A randomized-control design was used, comparing learning outcomes of students who received the incentive with those who did not. Results indicated that students given the incentive to use feedback had significantly higher normalized change scores on math items (d = .53), with stronger effects for students with low academic intrinsic motivation (d = .88 - 1.17).

    Lim, Sung-joo; Holt, Lori L

    2011-01-01

    Although speech categories are defined by multiple acoustic dimensions, some are perceptually weighted more than others and there are residual effects of native-language weightings in non-native speech perception. Recent research on nonlinguistic sound category learning suggests that the distribution characteristics of experienced sounds influence perceptual cue weights: Increasing variability across a dimension leads listeners to rely upon it less in subsequent category learning (Holt & Lotto, 2006). The present experiment investigated the implications of this among native Japanese learning English /r/-/l/ categories. Training was accomplished using a videogame paradigm that emphasizes associations among sound categories, visual information, and players' responses to videogame characters rather than overt categorization or explicit feedback. Subjects who played the game for 2.5h across 5 days exhibited improvements in /r/-/l/ perception on par with 2-4 weeks of explicit categorization training in previous research and exhibited a shift toward more native-like perceptual cue weights.

    Adolescents with autism spectrum disorder spend considerable time in media activities. Parents play an important role in shaping adolescents' responses to media. This study explored the mediation strategies that parents of adolescents with autism spectrum disorder used to manage television and video game use, factors associated with their use of different strategies, and whether mediation strategies changed over time. A secondary purpose was to examine whether parents applied different mediation strategies to adolescents with autism spectrum disorder versus siblings, and the factors that created stress related to managing media use. Parents of 29 adolescents with autism spectrum disorder and 16 siblings completed questionnaires at two time points. Parents most frequently supervised their television viewing by watching it with the adolescents, and used restrictive strategies to regulate their videogaming. Parents used similar strategies for siblings, but more frequently applied restrictive and instructive strategies for videogaming with adolescents with autism spectrum disorder than their siblings. Restrictive mediation of television viewing for the adolescents decreased significantly over the year. Adolescents' time spent in media activities, age, and behavior problems, and parents' concerns about media use were significant factors associated with the strategies that parents employed. Parents' stress related to the adolescents' behavioral and emotional responses to parental restrictions. © The Author(s) 2014.

    2014-03-01

    As mobile technologies and videogaming platforms are becoming increasingly prevalent in the realm of health and healthcare, so are the opportunities to use these resources to conduct behavioral interventions. The creation and empirical testing of game style interventions, however, is challenged by the requisite collaboration of multidisciplinary teams, including researchers and game developers who have different cultures, terminologies, and standards of evidence. Thus, traditional intervention development tools such as logic models and intervention manuals may need to be augmented by creating what we have termed "Game Playbooks" which are intervention guidebooks that are created by, understood by, and acceptable to all members of the multidisciplinary game development team. The purpose of this paper is to describe the importance and content of a Game Playbook created to aide in the development of a videogame intervention designed specifically for health behavior change in young teens as well as the process for creating such a tool. We draw on the experience of our research and game design team to describe the critical components of the Game Playbook and the necessity of creating such a tool.

    2014-08-01

    Well-designed digital games can deliver powerful experiences that are difficult to provide through traditional instruction, while traditional instruction can deliver formal explanations that are not a natural fit for gameplay. Combined, they can accomplish more than either can alone. An experiment tested this claim using the topic of statistics, where people's everyday experiences often conflict with normative statistical theories and a videogame might provide an alternate set of experiences for students to draw upon. The research used a game called Stats Invaders!, a variant of the classic videogame Space Invaders. In Stats Invaders!, the locations of descending alien invaders follow probability distributions, and players need to infer the shape of the distributions to play well. The experiment tested whether the game developed participants' intuitions about the structure of random events and thereby prepared them for future learning from a subsequent written passage on probability distributions. Community-college students who played the game and then read the passage learned more than participants who only read the passage.

    Prior research has demonstrated that psychological immersion (or "transportation") into virtual gaming worlds can heighten influence from health-promotion messages embedded in the backgrounds of gaming scenes. However, research to date has only studied the effectiveness of embedding graphic, fear-based messages in the background of violent, first-person videogames. This study sought to examine whether transportation into a nonviolent videogame can heighten persuasion from low-fear, nongraphic health messages. Willingness to drive under the influence of alcohol (DUI) was measured in an undergraduate sample (M AGE  = 19) at the start of the semester, and n = 220 returned 0-3 months later to play a car-racing videogame. All were randomly assigned to play either a version of the game containing background billboards that delivered simple, text-based anti-DUI messages or consumer advertising. Self-reported levels of transportation were assessed, as well as postgame willingness to DUI. Exposure to anti-DUI messages from within the game predicted lower postgame willingness to DUI. Moreover, replicating prior research, the effect of message exposure was largest among those who reported higher levels of pregame willingness to DUI, and higher levels of in-game transportation. This study replicates prior research by suggesting that immersive videogames that promote transportation can be used to effectively deliver health communications. Results also expand prior research by providing the first evidence that such effects can generalize when health messaging orients around nongraphic, lower fear messages embedded within immersive but lower fear videogames.

    Full Text Available Obesity is a rising problem among adolescents in modern societies; it results in long-term cardio-metabolic problems. Possible overlooked drivers of obesity and its consequent cardio-metabolic deficits include videogame addiction and the resulting curtailed sleep; both are growing problems among adolescents. The objective of this study is to examine possible associations among these concepts in adolescents, as a means to point to plausible interventions.Data were collected from 94 adolescents who play videogames and are enrolled in outpatient clinics, using surveys, wearable sleep monitors (FitBit, physical exams, and blood tests at three points in time. These data were subjected to structural equation modeling (SEM analyses and bootstrapping-based mediation testing procedures.Videogame addiction among adolescents was negatively associated with sleep duration (β = -0.24. Sleep duration was negatively associated with obesity (β = -0.30, which in turn was associated with elevated blood pressure (β = 0.26, low high-density lipoprotein cholesterol (β = -0.18, high triglycerides (β = 0.61, and high insulin resistance (β = 0.39. The model explained 36.2% of the variation in sleep duration, 32.7% of the variation in obesity, and between 12.8% and 28.1% of the variation in cardio-metabolic indicators. Post-hoc analyses indicated that curtailed sleep is a possible full mediator of the association between videogame addiction, abdominal obesity and the associated cardio-metabolic deficits.The findings point to possible information systems use lifestyle-health links, which behooves researchers and practitioners to pay closer attention to possible adverse health outcomes of technology-related addictions. Interventions that target problematic video-gaming and sleep should be devised as a possible means for improving adolescents' long-term cardio-metabolic health.

    Full Text Available The study builds upon monographs by Vladimir Bovan (2002 and Sunčica Denić (2003 on Manojlo Đorđević Prizrenac and tries to answer some unresolved questions for now: when, how and for what reasons Prizrenac came in Prague? What was he doing there and why did Austrian authorities arrest him? With the use of, until now, unknown sources in the Museum of Czech Literature in Prague and the Czech press from that period we concluded that Prizrenac arrived in Prague in March 1872, probably with the help of Belgrade publisher Velimir Valožić, to work as editor of the newly established Czech-Russian journal 'Slavic world' of Ondřej Günther-Prelučev, and only until May 3 the same year he was arrested for the telegram which was sent to Moscow newspapers. In August of that year he was convicted of treason and sentenced to 6 years in prison and eventually released in January in 1877. The study first analyzes 'Slavic world' and the period of Prizren in Prague until his arrest, as well as the background and circumstances of his departure from Belgrade. One of the results is the discovery of several previously unknown texts by journalist Manojlo Đorđević Prizrenac, regarding Kosovo and Metohija, as well as articles which he had such as 'Rights and demands of Serbia' and 'Škipetari'. .

    Amblyopia is a common neurodevelopmental disorder of vision that is characterised by visual impairment in one eye and compromised binocular visual function. Existing evidence-based treatments for children include patching the nonamblyopic eye to encourage use of the amblyopic eye. Currently there are no widely accepted treatments available for adults with amblyopia. The aim of this trial is to assess the efficacy of a new binocular, videogame-based treatment for amblyopia in older children and adults. We hypothesise that binocular treatment will significantly improve amblyopic eye visual acuity relative to placebo treatment. The BRAVO study is a double-blind, randomised, placebo-controlled multicentre trial to assess the effectiveness of a novel videogame-based binocular treatment for amblyopia. One hundred and eight participants aged 7 years or older with anisometropic and/or strabismic amblyopia (defined as ≥0.2 LogMAR interocular visual acuity difference, ≥0.3 LogMAR amblyopic eye visual acuity and no ocular disease) will be recruited via ophthalmologists, optometrists, clinical record searches and public advertisements at five sites in New Zealand, Canada, Hong Kong and Australia. Eligible participants will be randomised by computer in a 1:1 ratio, with stratification by age group: 7-12, 13-17 and 18 years and older. Participants will be randomised to receive 6 weeks of active or placebo home-based binocular treatment. Treatment will be in the form of a modified interactive falling-blocks game, implemented on a 5th generation iPod touch device viewed through red/green anaglyphic glasses. Participants and those assessing outcomes will be blinded to group assignment. The primary outcome is the change in best-corrected distance visual acuity in the amblyopic eye from baseline to 6 weeks post randomisation. Secondary outcomes include distance and near visual acuity, stereopsis, interocular suppression, angle of strabismus (where applicable) measured at

    Full Text Available Under the theoretical developments proposed by the Theory of the Firm, it is possible to understand the firm as the primary site for innovation. Innovation effort is justified by the need to generate solutions which should be validated in the market. This market validation process enables one to identify the life cycle of the solution, represented by the “S-curve”. Whether due to its sales volume, market share and even technological improvements, there is a sequence of events that are, invariably, repeated in all technologies: onset, growth, maturing and decay. This paper presents, based on a model for innovation expectation and potential, an analysis of the firms’ actions along different S-curves. To do this, sales volume historical data of videogame consoles in Japan were used. The most interesting finding is that the firms terminate the life cycle of each technology keeping, simultaneously, two or more different versions of the consoles.

    Full Text Available Video games are one of the first leisure alternatives in our society and generate millions of euros in profits annually. However, only 17% of its creators are women, which implies an important loss of creative capital and high economic gains that are not equitably distributed in a context of social inequality. Multiple factors, from the content of video games to the social environment, negatively influence women, creating a disaffection for video games. On the other hand, the masculinized environments and the lack of authority of the women around the videogames, curb the pretensions of the players to make the leap toward the professionalization in this industry. The objective of this article, through a bibliographical review, is to begin a research of the causes of the underrepresentation of women in the video game industry, in order to find solutions, create a more sustainable economy for Europe, an increase of equal spaces And greater job opportunities for women.

    Despite numerous health benefits, less than half of American adults engage in regular physical activity. Exercise videogames (EVG) may be a practical and attractive alternative to traditional forms of exercise. However there is insufficient research to determine whether EVG play alone is sufficient to produce prolonged engagement in physical activity or improvements in cardiovascular fitness and overall health risk. The goal of the present study is to test the efficacy of exercise videogames to increase time spent in moderate to vigorous physical activity (MVPA) and to improve cardiovascular risk indices among adults. Wii Heart Fitness is a rigorous 3-arm randomized controlled trial with adults comparing three 12-week programs: (1) supervised EVGs, (2) supervised standard exercise, and (3) a control condition. Heart rate is monitored continuously throughout all exercise sessions. Assessments are conducted at baseline, end of intervention (week 12), 6 and 9 months. The primary outcome is time spent in MVPA physical activity. Secondary outcomes include changes in cardiovascular fitness, body composition, blood lipid profiles and maintenance of physical activity through six months post-treatment. Changes in cognitive and affective constructs derived from Self Determination and Social Cognitive Theories will be examined to explain the differential outcomes between the two active treatment conditions. The Wii Heart Fitness study is designed to test whether regular participation in EVGs can be an adequate source of physical activity for adults. This study will produce new data on the effect of EVGs on cardiovascular fitness indices and prolonged engagement with physical activity. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Recent developments in hydrological modeling and biomass retrieval in complex mountain areas have heightened the need for accurate precipitation data at high spatial resolution. The Tropical Rainfall Measuring Mission (TRMM provides rainfall estimates for certain climate models in mountain ranges where rain gauges are lacking. TRMM precipitation estimates, however, inherently have large uncertainties because of their coarse spatial resolution. In this study, we investigate a statistical downscaling calibration procedure to derive high-spatial-resolution (1-km precipitation maps for the Tibetan Plateau using the satellite-based data set Enhanced Vegetation Index (EVI from the Moderate Resolution Imaging Spectroradiometer, a digital elevation model from the Shuttle Radar Topography Mission, and the TRMM 3B43 product. Spatial downscaling from 0.25° to 1 km was achieved by using the nonparametric statistic relationships between precipitation and EVI, altitude, slope, aspect, latitude, and longitude. An additive method was used to calibrate the downscaled precipitation data. The best 1-km resolution annual precipitation data for 2001–2012 over the Tibetan Plateau were generated through downscaling and additive calibration for most cases. The results show that the method improves the accuracy of rainfall estimates. Monthly 1-km precipitation data were also obtained by disaggregating 1-km annual downscaled estimates with monthly fractions of annual total precipitation. Monthly precipitation predictions are in good agreement with rain gauge data. The calibration of the monthly product with rain gauge data significantly reduced the bias value. Overall we conclude that the methodology is useful for areas with varied climate conditions and complex topography. These results have practical implications for calculating hydrological balances, mapping aboveground biomass, and assessing regional climate change.

  17. A New Urban Index for Expressing Inner-City Patterns Based on MODIS LST and EVI Regulated DMSP/OLS NTL

    Full Text Available With the rapid pace of urban expansion, comprehensively understanding urban spatial patterns, built environments, green-spaces distributions, demographic distributions, and economic activities becomes more meaningful. Night Time Lights (NTL images acquired through the Operational Linescan System of the US Defense Meteorological Satellite Program (DMSP/OLS NTL have long been utilized to monitor urban areas and their expansion characteristics since this system detects variation in NTL emissions. However, the pixel saturation phenomenon leads to a serious limitation in mapping luminance variations in urban zones with nighttime illumination levels that approach or exceed the pixel saturation limits of OLS sensors. Consequently, we propose an NTL-based city index that utilizes the Moderate-resolution Imaging Spectroradiometer (MODIS Land Surface Temperature (LST and Enhanced Vegetation Index (EVI images to regulate and compensate for desaturation on NTL images acquired from corresponding urban areas. The regulated results achieve good performance in differentiating central business districts (CBDs, airports, and urban green spaces. Consequently, these derived imageries could effectively convey the structural details of urban cores. In addition, compared with the Vegetation Adjusted NTL Urban Index (VANUI, LST-and-EVI-regulated-NTL-city index (LERNCI reveals superior capability in delineating the spatial structures of selected metropolis areas across the world, especially in the large cities of developing countries. The currently available results indicate that LERNCI corresponds better to city spatial patterns. Moreover, LERNCI displays a remarkably better “goodness-of-fit” correspondence with both the Version 1 Nighttime Visible Infrared Imaging Radiometer Suite Day/Night Band Composite (NPP/VIIRS DNB data and the WorldPop population-density data compared with the VANUI imageries. Thus, LERNCI can act as a helpful indicator for differentiating

    Full Text Available Nowadays the population sector of senior citizens has become very important. For that reason we need to work to increase our knowledge of how to keep and improve the quality of their lives. Among the factors that influence this quality we need to avoid dependency so that these citizens can look after themselves, being falls one of the main causes of their lack of mobility. For that reason we propose a balance training programme that combines floor exercises and videogames practise as a way to foster the positive effects of that training. Apart from bringing new technologies closer to a group of people who have little to do with it, this study shows the usefulness of these new technologies to improve balance. The outcome shows that the use of a videogame console improves the results obtained in a balance training programme based on exercises on wall bars, mats and unstable rubber platforms full of air.

    Commercially available, interactive videogames that use body movements for interaction are used clinically in burn rehabilitation and have been shown to facilitate functional range of motion (ROM) but their efficacy with burn patients has not yet been proven. The purpose of this pilot randomized control study was to prospectively compare planar and functional ROM, compliance, pain, enjoyment, and exertion in pediatric burn patients receiving two types of rehabilitation therapy. Seventeen school-aged children with 31 affected limbs who demonstrated limited shoulder ROM from burn injury were randomized to receive exercises using either standard therapy ROM activities (ST) or interactive videogame therapy (VGT). Patients received 3 weeks of the designated therapy intervention twice daily. They were then given a corresponding home program of the same type of therapy to perform regularly for 6 months. Standard goniometry and three-dimensional motion analysis during functional tasks were used to assess ROM. Measures were taken at baseline, 3 weeks, 3 months, and 6 months. Pain was measured before and after each treatment session during the 3-week intervention. There was no difference in compliance, enjoyment, or exertion between the groups. Patients in both the ST and VGT groups showed significant improvement in shoulder flexion (P videogames were equally effective as traditional therapy for overall ROM gains and resulted in quicker recovery of motion with less pain experienced. Such videogames are a useful adjunct to therapy and should be considered as part of a holistic approach to rehabilitation within the hospital and at home after discharge in pediatric patients recovering from burn injury.

    To investigate the feasibility of using video-games in a group setting and to compare the effectiveness of video-games as a group intervention to a traditional group intervention for improving physical activity in individuals with chronic stroke. A single-blind randomized controlled trial with evaluations pre and post a 3-month intervention, and at 3-month follow-up. Compliance (session attendance), satisfaction and adverse effects were feasibility measures. Grip strength and gait speed were measures of physical activity. Hip accelerometers quantified steps/day and the Action Research Arm Test assessed the functional ability of the upper extremity. Forty-seven community-dwelling individuals with chronic stroke (29-78 years) were randomly allocated to receive video-game (N=24) or traditional therapy (N=23) in a group setting. There was high treatment compliance for both interventions (video-games-78%, traditional therapy-66%), but satisfaction was rated higher for the video-game (93%) than the traditional therapy (71%) (χ(2)=4.98, P=0.026). Adverse effects were not reported in either group. Significant improvements were demonstrated in both groups for gait speed (F=3.9, P=0.02), grip strength of the weaker (F=6.67, P=0.002) and stronger hands (F=7.5, P=0.001). Daily steps and functional ability of the weaker hand did not increase in either group. Using video-games in a small group setting is feasible, safe and satisfying.

    Prior research has documented favorable effects of active and educational videogames among adolescents. However, research on potential negative effects of such games is limited. Scholars have called attention to games portraying sexualized female characters. The purpose of the current study was to experimentally investigate the effect of playing a videogame with a sexualized female character on adolescents' acceptance of rape myths and tolerance for sexual harassment. Fifty-seven secondary school pupils, 12-15 years of age, participated in a 2 (gender: boys versus girls)×2 (game character: nonsexualized versus sexualized female) factorial design experiment. Participants played a game for 15 minutes and were randomly assigned to one of the two game characters. Afterward, they completed established scales to assess rape myth acceptance and tolerance for sexual harassment. Analyses of variance showed greater acceptance of rape myths (P=0.039) and greater tolerance of sexual harassment (P=0.046) in adolescents who played with the sexualized woman compared with adolescents in the control condition. We did not find significant differences between boys and girls or any interaction effect between gender and game character. Findings suggest that gameplaying with a sexualized woman may increase adolescents' acceptance of rape myths and tolerance for sexual harassment. These findings highlight attention to the use of sexualized female game characters in (educational and active) videogames that target adolescents.

    This article asked and answered the question of whether there was evidence to support the use of videogames for promotion of wellness and fitness for people poststroke and those with cerebral palsy (CP). A literature search of PubMed, CINAHL, and PEDro using a population, intervention, and outcome (PIO) approach and the key words "stroke (or CP) AND video games (and synonyms) AND energy expenditure (EE) (and synonyms)" was conducted. It yielded two relevant references for people poststroke and five references for people with CP. The literature extraction and synthesis by the categories of the PIO indicated that most studies used only the population of interest, except two that compared the EE with that of healthy controls. The main finding is that both people poststroke (moderate severity) and people with CP (mild severity) can achieve moderate EE playing Wii(™) (Nintendo, Kyoto, Japan), PlayStation(®) (Sony, Tokyo, Japan), and Kinect(™) (Microsoft, Redmond, WA) games. Adults with CP of mild severity played the videogames at vigorous levels, whereas those with severe CP played them at low levels. There appears to be an interaction between development and severity that influences the exercise intensity measured by EE. The findings suggests that videogames are a gateway for wellness promotion.

The structure of feedback to the parents on their selection may influence what they learn from the game. Feedback Intervention Theory provides some guidance on the design of such messages. The structure of preferred performance feedback statements has not been investigated within serious videogames. Two feedback formats were tested for a player's preferences within the context of this videogame. Based on Feedback Intervention Theory, which proposes that threat to self-concept impairs feedback response, three-statement (a nonaffirming comment sandwiched between two affirming comments, called "Oreo" feedback, which should minimize threat to self-concept) and two-statement (a nonaffirming comment followed by an affirming comment) performance feedbacks were tailored to respondents. Tailoring was based on participants' report of frequency of use of effective and ineffective vegetable parenting practices and the reasons for use of the ineffective practices. Participants selected their preference between the two forms of feedback for each of eight ineffective vegetable parenting practices. In general, mothers ( n =81) (no male respondents) slightly preferred the "Oreo" feedback, but the pattern of preferences varied by demographic characteristics. Stronger relationships by income suggest the feedback structure should be tailored to family income. Future research with larger and more diverse samples needs to test whether perceived threat to self-concept mediates the response to feedback and otherwise verify these findings.

    Full Text Available The development of applications for mobile devices is a constantly growing market which and more and more enterprises support the development of applications for this kind of devices. In that sense, videogames for mobile devices have become very popular worldwide and are now part of highly profitable and competitive industry. Due to the diversity of platforms and mobile devices and the complexity of this kind of applications, the development time and the number of errors within that development process have increased. The productivity of the developers has also decreased due to the necessity of using many programming languages in the development process. One of the most popular strategies is to employ specialized people to perform the development tasks more efficiently, but this involves an increase of the costs, which makes some applications economically unviable. In this article we present the Gade4all Project, consisting in a new platform that aims to facilitate the development of videogames and entertainment software through the use of Domain Specific Languages and Model Driven Engineering. This tool makes possible for users without previous knowledge in the field of software development to create 2D videogames for multiplatform mobile devices in a simple and innovative way.

    Full Text Available Objective: Problematic video-gaming or social media use may seriously affect adolescents’ health status. However, it is not very well known which health-related problems are most strongly related to these issues. To inform the development of prevention and intervention strategies, this study aims to gain a better understanding of the health-related problems and demographical factors associated with problematic video-gaming or social media use in early adolescence. Method: A cross-sectional analysis was performed on data collected by two Municipal Health Services in the Netherlands in 2013-2014. In this survey among youth, 21,053 students from secondary schools (mean age 14.4 years completed a web-based questionnaire. Multivariate analyses were carried out to assess the strength of the associations between mental health problems, life-events, lifestyle and substance use as independent variables, and problematic video-gaming and problematic social media use as dependent variables. Results: Of the participating students, 5.7% reported problematic video-gaming and 9.1% problematic social media use. Problematic video-gaming was most strongly associated with conduct problems, suicidal thoughts (all medium effect sizes, OR ≥2, p<0.01, sedentary behavior (large effect size, OR ≥3, p<0.01, and male gender (large effect size. Problematic social media use was highly associated with conduct problems, hyperactivity and sedentary behavior (all medium effect sizes. Additionally, female gender and non-Western ethnicity were relevant demographics (large and medium effect size. Conclusions: Most mental health problems were consistently associated with both problematic video-gaming and problematic social media use, though associations were only practically relevant for conduct problems (both groups, suicidal thoughts (problematic video-gaming and hyperactivity (problematic social media use. This study also highlights sedentary behavior as health risk as it

  8. Strong Links Between Teleconnections and Ecosystem Exchange Found at a Pacific Northwest Old-Growth Forest from Flux Tower and MODIS EVI Data

    Variability in three Pacific teleconnection patterns are examined to see if net carbon exchange at a low-elevation, old-growth forest is affected by climatic changes associated with these periodicities. Examined are the Pacific Decadal Oscillation (PDO), Pacific/North American Oscillation (PNA) and El Nino-Southern Oscillation (ENSO). We use nine years of eddy covariance CO{sub 2}, H{sub 2}O and energy fluxes measured at the Wind River AmeriFlux site, Washington, USA and eight years of tower-pixel remote sensing data from the Moderate Resolution Imaging Spectroradiometer (MODIS) to address this question. We compute a new Composite Climate Index (CCI) based on the three Pacific Oscillations to divide the measurement period into positive- (2003 and 2005), negative- (1999 and 2000) and neutral-phase climate years (2001, 2002, 2004, 2006 and 2007). The forest transitioned from an annual net carbon sink (NEP = + 217 g C m{sup -2} year{sup -1}, 1999) to a source (NEP = - 100 g C m{sup -2} year{sup -1}, 2003) during two dominant teleconnection patterns. Net ecosystem productivity (NEP), water use efficiency (WUE) and light use efficiency (LUE) were significantly different (P < 0.01) during positive (NEP = -0.27 g C m{sup -2} day{sup -1}, WUE = 4.1 mg C/g H{sub 2}O, LUE = 0.94 g C MJ{sup -1}) and negative (NEP = +0.37 g C m{sup -2} day{sup -1}, WUE = 3.4 mg C/g H{sub 2}O, LUE = 0.83 g C MJ{sup -1}) climate phases. The CCI was linked to variability in the MODIS Enhanced Vegetation Index (EVI) but not to MODIS Fraction of absorbed Photosynthetically Active Radiation (FPAR). EVI was highest during negative climate phases (1999 and 2000) and was positively correlated with NEP and showed potential for using MODIS to estimate teleconnection-driven anomalies in ecosystem CO{sub 2} exchange in old-growth forests. This work suggests that any increase in the strength or frequency of ENSO coinciding with in-phase, low frequency Pacific oscillations (PDO and PNA) will likely increase

  9. Player–Game Interaction and Cognitive Gameplay: A Taxonomic Framework for the Core Mechanic of Videogames

    Full Text Available Cognitive gameplay—the cognitive dimension of a player’s experience—emerges from the interaction between a player and a game. While its design requires careful consideration, cognitive gameplay can be designed only indirectly via the design of game components. In this paper, we focus on one such component—the core mechanic—which binds a player and game together through the performance of essential interactions. Little extant research has been aimed at developing frameworks to support the design of interactions within the core mechanic with cognitive gameplay in mind. We present a taxonomic framework named INFORM (Interaction desigN For the cORe Mechanic to address this gap. INFORM employs twelve micro-level elements that collectively give structure to any individual interaction within the core mechanic. We characterize these elements in the context of videogames, and discuss their potential influences on cognitive gameplay. We situate these elements within a broader framework that synthesizes concepts relevant to game design. INFORM is a descriptive framework, and provides a common vocabulary and a set of concepts that designers can use to think systematically about issues related to micro-level interaction design and cognitive gameplay.

    Active games require whole-body movement and may be an innovative tool to substitute sedentary pastime with more active time and may therefore contribute to adolescents' health. To inform strategies aimed at reducing sedentary behavior by replacing non-active with active gaming, perceptions and context of active and non-active gaming are explored. Six focus groups were conducted with adolescents 12-16 years old representing a range of education levels. A semistructured question route was used containing questions about perceptions and the context of gaming. The adolescents had positive attitudes toward active gaming, especially the social interactive aspect, which was greatly appreciated. A substantial number of adolescents enjoyed non-active games more than active ones, mainly because of better game controls and more diversity in non-active games. Active games were primarily played when there was a social gathering. Few game-related rules and restrictions at home were reported. Given the positive attitudes of adolescents and the limited restrictions for gaming at home, active videogames may potentially be used in a home setting as a tool to reduce sedentary behavior. However, to make active games as appealing as non-active games, attention should be paid to the quality, diversity, and sustainability of active games, as these aspects are currently inferior to those of traditional non-active games.

    The energy required to play active videogames (AVGs) has been reported on in the literature; however, little is known about how children use such games in their home environment. The aim of this study was to investigate children's use of AVGs and the association among AVG use, other screen-based activities, and physical activity levels. Eight hundred and twenty children 12.1 (0.6) years of age participated. Physical activity levels, sedentary screen-based activities, and AVG use were investigated. Differences across genders and deprivation indices were also analyzed. Fifty-eight percent of children met minimal physical activity guidelines. Forty-seven percent of children exceeded screen time recommendations. Of those who had access to AVGs, more children played sedentary games (or active games in a sedentary manner [68 percent]) than active games (55 percent) on AVG consoles. Furthermore, sedentary games were played for longer than active games. AVG play was positively correlated with reported time spent watching television (P=0.02). In free-living conditions AVG consoles are being used by more children and for longer durations as sedentary screen-based devices rather than active screen-based devices.

    This review systematically evaluated the effects of active videogames (AVGs) on physical activity (PA) and related outcomes in healthy children. Electronic databases were searched to retrieve articles published from January 2000 through August 2013. Included were original studies published in English, in peer-reviewed journals, that included at least one subgroup of healthy participants not older than 18 years, and that measured at least one PA-related cognitive, psychosocial, or behavioral outcome. All study designs were included, but only intervention studies with PA comparison between groups or across time were assessed for methodological quality. Evidence strength for intervention studies was stratified by settings (including the free-living home setting, the school, community, or primary care setting with structured AVG sessions [i.e., AVG play of participants was organized by teachers or researchers], and multiple settings). Fifty-four articles were identified, including 32 studies that examined the immediate PA effects (i.e., energy expenditure and PA levels during AVG play), one survey study, and 21 intervention studies aimed to promote PA. AVGs led to light- to moderate-intensity PA among studies of immediate PA outcomes. No effect was identified of AVGs on PA in the home setting. Moderate evidence was found that structured AVG play could improve PA. Inconclusive evidence was found for the effect of AVGs on PA in multiple settings. The present review does not support using AVGs alone in the home setting to promote PA. Structured AVG play has the potential to promote PA in children.

    The Nintendo Wii Fit™ may provide an affordable alternative to traditional biofeedback or virtual reality systems for retraining or improving motor function in populations with impaired balance. The purpose of this study was to evaluate postural control strategies healthy individuals use to play Wii Fit™ videogames. Sixteen young adults played 10 trials of Ski Slalom and Soccer Heading respectively. Centre of pressure (COP) excursion and three-dimensional movement data were acquired to determine variability in medial-lateral COP sway and shoulder-pelvic movement. While there was no difference in medial-lateral COP variability between games during trial 1, there was a significant difference after 10 trials. COP sway increased (59-75 mm) for Soccer Heading while it decreased (67-33 mm) for Ski Slalom from trial 1 to trial 10. During Ski Slalom participants demonstrated decreased shoulder and pelvic movement combined with increased pelvic-shoulder coupling. Conversely, participants demonstrated greater initial shoulder tilt when playing Soccer Heading, with no reduction in pelvic rotation and tilt. Participants decreased pelvic and trunk movements when skiing, suggesting a greater contribution of lower extremity control while they primarily used a trunk strategy to play Soccer Heading.

    Television viewing and videogame use (TV/VG) appear to be associated with some childhood behavioral problems. There are no studies addressing this problem in the United Arab Emirates. One hundred ninety-seven school children (mean age, 8.7 ± 2.1 years) were assessed. Child Behavior Checklist (CBCL) subscale scores and socio-demographic characteristics were compared between children who were involved with TV/VG more than 2 hours/day and those involved less than 2 hours/day (the recommended upper limit by The American Academy of Pediatrics). Thirty-seven percent of children who were involved with TV/VG time of more than 2 hours/day scored significantly higher on CBCL syndrome scales of withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, internalizing problems, externalizing problems and the CBCL total scores compared with their counterparts. Moreover, these children were younger in birth order and had fewer siblings. After controlling for these confounders using logistic regression, we found that TV/VG time more than 2 hours/day was positively associated with withdrawn (p = 0.008), attention problem (p = 0.037), externalizing problems (p = 0.007), and CBCL total (p = 0.014). Involvement with TV/VG for more than 2 hours/day is associated with more childhood behavioral problems. Counteracting negative effects of the over-involvement with TV/VG in children requires increased parental awareness.

    Full Text Available This article raises a number of questions: Where do the parts on gaming circuit boards come from? Whose hands made them? Under what conditions? What happens to the materials in a device once we discard it? Perhaps predictably, these questions do not commonly come up when videogames are studied diegetically, based solely on what is expressed on the screen (Montfort; Kirschenbaum 27-28. However, the material study of hardware offers an approach that highlights material traces that may otherwise go unnoticed by gamers and scholars alike. Furthermore, it prompts an important question in the context of game studies: What do gamers and scholars tend to ignore when they are at once enthralled and distracted by the experiences afforded by the video, audio, and textual elements of games? As I argue below, circuit bending encourages a deep engagement with hardware that offers a materials-first approach and brings awareness to issues of exploitation not commonly raised and recorded by screen-centric analysis alone.

    Videogame play (VGP) has been associated with numerous preferred and non-preferred effects. However, the effects of VGP on the development of microstructural properties in children, particularly those associated with negative psychological consequences of VGP, have not been identified to date. The purpose of this study was to investigate this issue through cross-sectional and longitudinal prospective analyses. In the present study of humans, we used the diffusion tensor imaging mean diffusivity (MD) measurement to measure microstructural properties and examined cross-sectional correlations with the amount of VGP in 114 boys and 126 girls. We also assessed correlations between the amount of VGP and longitudinal changes in MD that developed after 3.0±0.3 (s.d.) years in 95 boys and 94 girls. After correcting for confounding factors, we found that the amount of VGP was associated with increased MD in the left middle, inferior and orbital frontal cortex; left pallidum; left putamen; left hippocampus; left caudate; right putamen; right insula; and thalamus in both cross-sectional and longitudinal analyses. Regardless of intelligence quotient type, higher MD in the areas of the left thalamus, left hippocampus, left putamen, left insula and left Heschl gyrus was associated with lower intelligence. We also confirmed an association between the amount of VGP and decreased verbal intelligence in both cross-sectional and longitudinal analyses. In conclusion, increased VGP is directly or indirectly associated with delayed development of the microstructure in extensive brain regions and verbal intelligence.

    In the last forty years, videogames have gone from a dot bouncing between two lines ("PONG", 1972), to sprawling $150 million enterprises that teams of hundreds work on for years, with fully-developed, novelistic stories and graphics that can be arrestingly realistic and engrossing. Video games - and now virtual reality - conjure superhero sagas, alien wars, and historic battlefields. Yet the game industry has given little thought to using this powerful storytelling medium to explain the many wondrous facets of regular old reality. The techniques and technologies of game design are offering an ever-more potent tool for explaining the processes of science. Want to explain fracking to someone unfamiliar with its strange mechanics? We did - we built a game-like graphic that asks learners to frack a well themselves, on an iPad. They use their fingergs to drill the well, inject the water and solvents, and gather the resulting oil and gas - not to mention seeing the potential environmental ramifications. How about explaining heart or brain surgery on a 3-month old child? Or showing students how a nerve cell works by allowing them to fly into it and build the proteins that enable the nerve to fire? We've done all these, and are continuing to add new dimensions to immersive teaching and explanatory storytelling. We'll share insights we've gathered along the way.

    This paper analyses the associations between Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI) on the prevalence of schistosomiasis and the presence of Biomphalaria glabrata in the state of Minas Gerais (MG), Brazil. Additionally, vegetation, soil and shade fraction images were created using a Linear Spectral Mixture Model (LSMM) from the blue, red and infrared channels of the Moderate Resolution Imaging Spectroradiometer spaceborne sensor and the relationship between these images and the prevalence of schistosomiasis and the presence of B. glabrata was analysed. First, we found a high correlation between the vegetation fraction image and EVI and second, a high correlation between soil fraction image and NDVI. The results also indicate that there was a positive correlation between prevalence and the vegetation fraction image (July 2002), a negative correlation between prevalence and the soil fraction image (July 2002) and a positive correlation between B. glabrata and the shade fraction image (July 2002). This paper demonstrates that the LSMM variables can be used as a substitute for the standard vegetation indices (EVI and NDVI) to determine and delimit risk areas for B. glabrata and schistosomiasis in MG, which can be used to improve the allocation of resources for disease control.

    Full Text Available Abstract Background Variant translocations t(9;22 occur in 5 to 10% of newly diagnosed CMLs and additional genetic changes are present in 60–80% of patients in blast crisis (BC. Here, we report on a CML patient in blast crisis presenting with a four-way variant t(9;22 rearrangement involving the EVI1 locus. Methods Dual-colour Fluorescence In Situ Hybridisation was performed to unravel the different cytogenetic aberrations. Expression levels of EVI1 and BCR/ABL1 were investigated using real-time quantitative RT-PCR. Results In this paper we identified a patient with a complex 4-way t(3;9;17;22 which, in addition to BCR/ABL1 gene fusion, also resulted in EVI1 rearrangement and overexpression. Conclusion This report illustrates how a variant t(9;22 translocation can specifically target a second oncogene most likely contributing to the more aggressive phenotype of the disease. Molecular analysis of such variants is thus warranted to understand the phenotypic consequences and to open the way for combined molecular therapies in order to tackle the secondary oncogenic effect which is unresponsive to imatinib treatment.

    Although several types of satellite data provide temporal information of the land use at no cost, digital satellite data applications for agricultural studies are limited compared to applications for forest management. This study assessed the suitability of vegetation indices derived from the TERRA-Moderate Resolution Imaging Spectroradiometer (MODIS) sensor and SPOT-VEGETATION (VGT) sensor for identifying corn growth in western Mexico. Overall, the Normalized Difference Vegetation Index (NDVI) composites from the VGT sensor based on bi-directional compositing method produced vegetation information most closely resembling actual crop conditions. The NDVI composites from the MODIS sensor exhibited saturated signals starting 30 days after planting, but corresponded to green leaf senescence in April. The temporal NDVI composites from the VGT sensor based on the maximum value method had a maximum plateau for 80 days, which masked the important crop transformation from vegetative stage to reproductive stage. The Enhanced Vegetation Index (EVI) composites from the MODIS sensor reached a maximum plateau 40 days earlier than the occurrence of maximum leaf area index (LAI) and maximum intercepted fraction of photosynthetic active radiation (fPAR) derived from in-situ measurements. The results of this study showed that the 250-m resolution MODIS data did not provide more accurate vegetation information for corn growth description than the 500-m and 1000-m resolution MODIS data.

    2017-04-01

    We compare physical activity during bouts of sedentary videogaming (SVG), active videogaming (AVG), and paced walking in children with and without autism spectrum disorder (ASD) to determine the effectiveness of AVG in providing moderate-to-vigorous physical activity. Participants included nine males (8-11 years old) with ASD and eight age-matched males who were typically developing. Both groups had anthropometric and motor proficiency (Movement Assessment Battery for Children II) measures taken before testing. Participants attended three randomly assigned acquisition sessions: 20 minutes of paced walking at 4.5 metabolic equivalents, AVG, and SVG. Videogaming occurred on an Xbox ® Kinect. An Actical accelerometer provided activity counts (AC) and percentage of time in moderate-to-vigorous physical activity (%MVPA). These were compared using 3 × 2 repeated measures analysis of variance for each measure. Main effects for conditions existed for %MVPA (P < 0.0001) and AC (P < 0.0001). Post hoc Bonferroni comparisons indicated that AVG had significantly higher AC (P < 0.001) and % MVPA (P < 0.001) than SVG, but was significantly lower than paced walking (AC P < 0.001; %MVPA P < 0.01). Overall, participants spent 76.25% of their time in MVPA during AVG compared to 99.4% during paced walking and 2.31% in SVG. No main effects for groups or group by condition interaction effects were found for either measure. AVG may provide an appealing means by which all individuals can increase their overall physical activity levels, although AVG should not be seen as a replacement for walking or other forms of PA. Although further research is necessary, the finding that both groups performed similarly in AVG suggests that games can potentially be played without modifications or adaptations to gaming units, which may provide several advantages in terms of social/cost/ease of accessing unit.

    Traumatic brain injury (TBI) disrupts the central and executive mechanisms of arm(s) and postural (trunk and legs) coordination. To address these issues, we developed a 3D immersive videogame--Octopus. The game was developed using the basic principles of videogame design and previous experience of using videogames for rehabilitation of patients with acquired brain injuries. Unlike many other custom-designed virtual environments, Octopus included an actual gaming component with a system of multiple rewards, making the game challenging, competitive, motivating and fun. Effect of a short-term practice with the Octopus game on arm-postural coordination in patients with TBI was tested. The game was developed using WorldViz Vizard software, integrated with the Qualysis system for motion analysis. Avatars of the participant's hands precisely reproducing the real-time kinematic patterns were synchronized with the simulated environment, presented in the first person 3D view on an 82-inch DLP screen. 13 individuals with mild-to-moderate manifestations of TBI participated in the study. While standing in front of the screen, the participants interacted with a computer-generated environment by popping bubbles blown by the Octopus. The bubbles followed a specific trajectory. Interception of the bubbles with the left or right hand avatar allowed flexible use of the postural segments for balance maintenance and arm transport. All participants practiced ten 90-s gaming trials during a single session, followed by a retention test. Arm-postural coordination was analysed using principal component analysis. As a result of the short-term practice, the participants improved in game performance, arm movement time, and precision. Improvements were achieved mostly by adapting efficient arm-postural coordination strategies. Of the 13 participants, 10 showed an immediate increase in arm forward reach and single-leg stance time. These results support the feasibility of using the custom-made 3D

    Abstract A serious videogame is being developed to train parents of preschool children in selecting and using parenting practices that are likely to encourage their child to eat more vegetables. The structure of feedback to the parents on their selection may influence what they learn from the game. Feedback Intervention Theory provides some guidance on the design of such messages. The structure of preferred performance feedback statements has not been investigated within serious videogames. Two feedback formats were tested for a player's preferences within the context of this videogame. Based on Feedback Intervention Theory, which proposes that threat to self-concept impairs feedback response, three-statement (a nonaffirming comment sandwiched between two affirming comments, called “Oreo” feedback, which should minimize threat to self-concept) and two-statement (a nonaffirming comment followed by an affirming comment) performance feedbacks were tailored to respondents. Tailoring was based on participants' report of frequency of use of effective and ineffective vegetable parenting practices and the reasons for use of the ineffective practices. Participants selected their preference between the two forms of feedback for each of eight ineffective vegetable parenting practices. In general, mothers (n=81) (no male respondents) slightly preferred the “Oreo” feedback, but the pattern of preferences varied by demographic characteristics. Stronger relationships by income suggest the feedback structure should be tailored to family income. Future research with larger and more diverse samples needs to test whether perceived threat to self-concept mediates the response to feedback and otherwise verify these findings. PMID:24761320

    Method for physiologically modulating videogames and simulations includes utilizing input from a motion-sensing video game system and input from a physiological signal acquisition device. The inputs from the physiological signal sensors are utilized to change the response of a user's avatar to inputs from the motion-sensing sensors. The motion-sensing system comprises a 3D sensor system having full-body 3D motion capture of a user's body. This arrangement encourages health-enhancing physiological self-regulation skills or therapeutic amplification of healthful physiological characteristics. The system provides increased motivation for users to utilize biofeedback as may be desired for treatment of various conditions.

    2014-08-01

    This article reviews the available literature about the use of novel methods of rehabilitation using virtual reality interventions for people living with posttraumatic brain injuries. The MEDLINE, EMBASE, SCOPUS, and Cochrane Library databases were searched using the terms "virtual reality" OR "video games" AND "traumatic brain injury." Included studies investigated therapeutic use of virtual reality in adults with a brain trauma resulting from acquired closed head injury, reported outcomes that included measures of motor or cognitive functionality, and were published in a peer-reviewed journal written in English. Eighteen articles fulfilled inclusion criteria. Eight were case studies, five studies had a quasi-experimental design with a pre-post comparison, and five were pilot randomized control trials or comparative studies. The virtual reality systems used were commercial or custom designed for the study and ranged from expensive, fully immersive systems to cheap online games or videogames. In before-after comparisons, improvements in balance were seen in four case studies and two small randomized control trials. Between-group comparisons in these randomized control trials showed no difference between virtual reality and traditional therapy. Post-training improvements were also seen for upper extremity functions (five small studies) and for various cognitive function measures (four case studies and one pilot randomized control trial). Attitudes of participants toward virtual reality interventions was more positive than for traditional therapy (three studies). The evidence that the use of virtual reality in rehabilitation of traumatic brain injury improves motor and cognitive functionality is currently very limited. However, this approach has the potential to provide alternative, possibly more affordable and available rehabilitation therapy for traumatic brain injury in settings where access to therapy is limited by geographical or financial constraints.

    The present study (1) explored the attractive features that affect Chinese primary school children's preferences of active videogames (AVGs) and (2) contrasted these findings with those in the Western literature. A total of 22 Chinese primary school children were recruited and interviewed. Four AVGs (Wii "Boxing," "Wii Fit™ Plus Obstacle Run"; "EyeToy Knockout", "EyeToy Keep ups") from two commercial consoles (Nintendo® Wii™ and Sony PlayStation ® 2 "EyeToy ® ") were employed. Participants used four selected AVGs for 3 minutes each. After each play period, children (1) described the strengths and weaknesses of each game as well as rated the attractive features of each game based on a 16-item questionnaire and (2) rated up to 5 items that were most influential regarding their AVG preferences. Participants indicated that control was the most significant feature, followed by feedback, goal, and graphics. The top five rated features imply that the perception of competence was the most appealing aspect and expected outcome of Chinese children who play AVGs. Compared with the Western findings regarding attractive AVG features, the present study found certain similarities as well as significant differences among Chinese AVG players. Based on the present study, control, feedback, goal, and graphics are the most significant features that attract Chinese children to play AVGs. Physical exertion, social interaction, competition, and learning outcomes, which are valued according to Western studies, were not mentioned as significant features by Chinese children. These findings demonstrate a need to investigate the effect of cultural background in AVG study design.

  13. Examining neural correlates of skill acquisition in a complex videogame training program

    Full Text Available Acquisition of complex skills is a universal feature of human behavior that has been conceptualized as a process that starts with intense resource dependency, requires effortful cognitive control, and ends in relative automaticity on the multi-faceted task. The present study examined the effects of different theoretically-based training strategies on cortical recruitment during acquisition of complex videogame skills. Seventy-five participants were recruited and assigned to one of three training groups: Fixed Emphasis Training (FET, in which participants practiced the game, Hybrid Variable Priority Training (HVT, in which participants practiced using a combination of part-task training and variable priority training, or a Control group that received limited game play. After 30 hours of training, game data indicated a significant advantage for the two training groups relative to the control group. The HVT group demonstrated enhanced benefits of training, as indexed by an improvement in overall game score and a reduction in cortical recruitment post-training. Specifically, while both groups demonstrated a significant reduction of activation in attentional control areas, namely the right middle frontal gyrus, right superior frontal gyrus, and the ventral medial prefrontal cortex, participants in the control group continued to engage these areas post-training, suggesting a sustained reliance on attentional regions during challenging task demands. The HVT group showed a further reduction in neural resources post-training compared to the FET group in these cognitive control regions, along with reduced activation in the motor and sensory cortices and the posteromedial cortex. Findings suggest that training, specifically one that emphasizes cognitive flexibility can reduce the attentional demands of a complex cognitive task, along with reduced reliance on the motor network.

  14. From Losing to Loss: Exploring the Expressive Capacities of Videogames Beyond Death as Failure

    Directory of Open Access Journals (Sweden)

    Sabine Harrer

    2013-12-01

    Full Text Available In games, loss is as ubiquitous as it is trivial. One reason for this has been found in the established convention of on-screen character death as a signifier for failure (Klastrup 2006; Grant 2011; Johnson 2011. If that’s all that games have to offer in terms of addressing an existential trope of human experience, the worried protectionist concludes, shouldn’t we dismiss this intrinsically flat medium as inferior to more established media forms such as film or literature? (Ebert 2010. Contrary to this view, this paper discusses gameplay examples that shed light on how this medium might leverage its expressive resources to arrive at rich representations of loss. First, the notion of loss implied in Sigmund Freud’s work “Mourning and Melancholia” (1917 will be discussed in relation to losing in games. Looking at procedurality, fictional alignment and experiential metaphor as three expressive gameplay devices identified by Doris Rusch (2009 will help explain the expressive shortcoming of losing and lay out what is at stake with profound gameplay expression. Moreover, it will serve as the keywords structuring the following analysis of three videogames, Final Fantasy VII (1997, Ico (2001 and Passage (2007, and their design decisions fostering deep representations of loss. Keeping the Freudian notion of loss in mind, we can trace its repercussions on the three expressive dimensions respectively. Following a separate analysis of each gameplay example, the last section will discuss some commonalities and differences and arrive at the identification of desired object, permanent disruption and linearity as design aspects modeling loss in more compelling ways than losing.

    Full Text Available Background: Several studies have highlighted the implications of impulsivity and novelty seeking for both the maintenance and the process of recovery from bulimia nervosa. Cognitive behavioral therapy (CBT is the treatment of choice for bulimia nervosa, but for some cases, this treatment alone might not be sufficient for reducing the high levels of impulsivity. The paper presents a case report of a patient with bulimia nervosa, examining the effectiveness of using a videogame (Playmancer as an additional intervention designed to address impulsivity. Design: Psychometric and neuropsychological measures were collected at baseline. After this assessment, Playmancer was applied prior to CBT, following an A-B-A-C-A single case experimental design. Impulsivity levels were assessed with the Conners’ Continuous Performance Test II (CPT-II. After the Playmancer treatment, the patient started CBT, and the levels of impulsivity were recorded again. Finally, psychometric and neuropsychological measures were collected after treatment. Weekly frequency of binges and vomiting were also recorded during the entire procedure. Results: After the videogame intervention, psychometric measures such as anxiety levels, impulsivity and novelty seeking decreased. Regarding the neuropsychological measures, impulsivity levels (measured with the CPT-II progressively decreased throughout the intervention, and an improvement in decision making capacities was observed. Furthermore, the frequency of binges also decreased during and after the videogame intervention. Discussion: This case report suggests that using the Playmancer videogame to reduce impulsivity prior to CBT may enhance the final results of the treatment for bulimia nervosa.

    The use of virtual reality-based tasks for studying memory has increased considerably. Most of the studies that have looked at child population factors that influence performance on such tasks have been focused on cognitive variables. However, little attention has been paid to the impact of non-cognitive skills. In the present paper, we tested 52 typically-developing children aged 5–12 years in a virtual object-location task. The task assessed their spatial short-term memory for the location of three objects in a virtual city. The virtual task environment was presented using a 3D application consisting of a 120″ stereoscopic screen and a gamepad interface. Measures of learning and displacement indicators in the virtual environment, 3D perception, satisfaction, and usability were obtained. We assessed the children’s videogame experience, their visuospatial span, their ability to build blocks, and emotional and behavioral outcomes. The results indicate that learning improved with age. Significant effects on the speed of navigation were found favoring boys and those more experienced with videogames. Visuospatial skills correlated mainly with ability to recall object positions, but the correlation was weak. Longer paths were related with higher scores of withdrawal behavior, attention problems, and a lower visuospatial span. Aggressiveness and experience with the device used for interaction were related with faster navigation. However, the correlations indicated only weak associations among these variables.

    Chromosomal rearrangements involving NUP98 gene have been associated with human leukemias such as de novo AML, therapy-related AML (t-AML), myelodysplastic syndrome (MDS), and chronic myeloid leukemia (CML). Genetic fusion NUP98-HOXA9, caused by t(7;11)(p15;p15), is a recurrent cytogenetic alteration in de novo acute myeloid leukemia (AML) usually found in young Asian patients and its description in therapy-related myeloid neoplasms (t-MN) is rare. Only one Asian case with molecular demonstration of the NUP98-HOXA9 fusion has been reported in therapy-related leukemia. NUP98-HOXA9 leukemogenic mechanism is derived from the transcription factor activity of the chimeric protein, which enhances the expression of genes related to cellular differentiation arrest and proliferation. We studied a Caucasian woman with a therapy-related acute myeloid leukemia after Ewing's sarcoma. Molecular demonstration of the genetic fusion NUP98-HOXA9 was performed by RT-PCR, and gene expression was analyzed by real-time PCR, including four AML patients with MLL rearrangements for comparative analysis. Cytologic and flow cytometric analysis was also carried out. After cytologic and flow cytometric analysis diagnostics was therapy-related myeloid neoplasm (t-MN). The major component of blasts in the acute leukemia was with neutrophilic differentiation, but 13% erythroid lineage blasts were also found. Cytogenetic and FISH analysis revealed t(7;11)(p15;p15) and NUP98-HOXA9 fusion gene was demonstrated. Gene expression analysis showed upregulation of EVI1 and MEIS1 in the index patient, both of them previously related to a worst outcome. In this work, we include a detailed molecular, clinical, cytological, and cytometric study of the second t-AML bearing NUP98-HOXA9 genetic fusion. © 2015 John Wiley & Sons Ltd.

    The Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) mission was recently selected by NASA as part of the Earth Venture-Instrument (EVI-3) program. The overarching goal for TROPICS is to provide nearly all-weather observations of 3-D temperature and humidity, as well as cloud ice and precipitation horizontal structure, at high temporal resolution to conduct high-value science investigations of tropical cyclones, including: (1) relationships of rapidly evolving precipitation and upper cloud structures to upper-level warm-core intensity and associated storm intensity changes; (2) the evolution of precipitation structure and storm intensification in relationship to environmental humidity fields; and (3) the impact of rapid-update observations on numerical and statistical intensity forecasts of tropical cyclones. TROPICS will provide rapid-refresh microwave measurements (median refresh rate of 21 minutes for the baseline mission) over the tropics that can be used to observe the thermodynamics of the troposphere and precipitation structure for storm systems at the mesoscale and synoptic scale over the entire storm lifecycle. TROPICS comprises 12 CubeSats in three low-Earth orbital planes. Each CubeSat will host a high performance radiometer to provide temperature profiles using seven channels near the 118.75 GHz oxygen absorption line, water vapor profiles using 3 channels near the 183 GHz water vapor absorption line, imagery in a single channel near 90 GHz for precipitation measurements (when combined with higher resolution water vapor channels), and a single channel at 206 GHz that is more sensitive to precipitation-sized ice particles. This observing system offers an unprecedented combination of horizontal and temporal resolution to measure environmental and inner-core conditions for tropical cyclones on a nearly global scale and is a major leap forward in the temporal resolution of several key

    OBJECTIVE To determine whether gender or interest in pursuing specialty certification in internal medicine or surgery was associated with video-gaming, 3-D spatial analysis, or entry-level laparoscopic skills in third-year veterinary students. DESIGN Cross-sectional study. SAMPLE A convenience sample of 68 (42 female and 26 male) third-year veterinary students. PROCEDURES Participants completed a survey asking about their interest in pursuing specialty certification in internal medicine or surgery. Subsequently, participants' entry-level laparoscopic skills were assessed with 3 procedures performed in box trainers, their video-gaming skills were tested with 3 video games, and their 3-D spatial analysis skills were evaluated with the Purdue University Visualization of Rotations Spatial Test. Scores were assigned for laparoscopic, video-gaming, and 3-D spatial analysis skills. RESULTS Significantly more female than male students were interested in pursuing specialty certification in internal medicine (23/42 vs 7/26), and significantly more male than female students were interested in pursuing specialty certification in surgery (19/26 vs 19/42). Males had significantly higher video-gaming skills scores than did females, but spatial analysis and laparoscopic skills scores did not differ between males and females. Students interested in pursuing specialty certification in surgery had higher video-gaming and spatial analysis skills scores than did students interested in pursuing specialty certification in internal medicine, but laparoscopic skills scores did not differ between these 2 groups. CONCLUSIONS AND CLINICAL RELEVANCE For this group of students, neither gender nor interest in specialty certification in internal medicine versus surgery was associated with entry-level laparoscopy skills.

    To investigate the feasibility of implementing a video-game exercise programme for older people with chronic low back pain (LBP). Single-centred single-blinded randomised controlled trial (RCT). Physiotherapy outpatient department in a public hospital in Western Sydney, Australia. We will recruit 60 participants over 55 years old with chronic LBP from the waiting list. Participants will be randomised to receive video-game exercise (n=30) or to remain on the waiting list (n=30) for 8 weeks, with follow up at 3 and 6 months. Participants engaging in video-game exercises will be unsupervised and will complete video-game exercise for 60minutes, 3 times per week. Participants allocated to remain on the waiting list will be encouraged to maintain their usual levels of physical activity. The primary outcomes for this feasibility study will be study processes (recruitment and response rates, adherence to and experience with the intervention, and incidence of adverse events) relevant to the future design of a large RCT. Estimates of treatment efficacy (point estimates and 95% confidence intervals) on pain self-efficacy, care seeking, physical activity, fear of movement/re-injury, pain, physical function, disability, falls-efficacy, strength, and walking speed, will be our secondary outcome measures. Recruitment for this trial began in November 2015. This study describes the rationale and processes of a feasibility study investigating a video-game exercise programme for older people with chronic LBP. Results from the feasibility study will inform on the design and sample required for a large multicentre RCT. Australian New Zealand Clinical Trials Registry: ACTRN12615000703505.

    The purpose of this study was to examine the effect of active videogames (AVGs) on underserved minority children's on-task classroom behavior, academic effort, and fitness. A one group pre- and posttest repeated measures design was used. In Fall 2013, 95 fourth grade children (57 boys, 38 girls; 96% of minority) from three classes at an underserved urban elementary school participated in teacher-supervised AVG activities (e.g., Wii Sports, Xbox Just Dance). Specifically, students participated in a 50-minute weekly AVG program at school for 6 weeks. Children's academic effort was evaluated by classroom teachers using a validated scale that assessed activity, attention, conduct, and social/emotional behavior. Moreover, children's classroom behavior was observed immediately before and after each AVG session by trained researchers. Finally, cardiovascular fitness was also measured. A paired t-test was used to assess teacher-rated student effort, while one-way (gender) analysis of variance (ANOVA) with repeated measures was performed to analyze children's on-task classroom behavior. There was a significant effect on children's effort between the first (mean = 3.24, SD = 0.75) and last week (mean = 3.41, SD = 0.73) assessments, t = 2.42, P = 0.02. In addition, there was a significant effect on classroom behavior, F = 33.103, P < 0.01. In detail, children scored significantly higher on on-task behavior during the post-AVG observation (mean = 81.4, SD = 12.3) than seen during the pre-AVG observation (mean = 69.8, SD = 14.9). However, no main effect was indicated for gender, F = 0.39, P = 0.54. No significant improvement in cardiovascular fitness was observed, although slight improvements were seen. Offering an AVG program at school could improve underserved minority children's classroom on-task behavior and academic effort. Future studies may include a control group to further confirm the effectiveness of AVG

Unlike many other custom-designed virtual environments, Octopus included an actual gaming component with a system of multiple rewards, making the game challenging, competitive, motivating and fun. Effect of a short-term practice with the Octopus game on arm-postural coordination in patients with TBI was tested. Methods The game was developed using WorldViz Vizard software, integrated with the Qualysis system for motion analysis. Avatars of the participant's hands precisely reproducing the real-time kinematic patterns were synchronized with the simulated environment, presented in the first person 3D view on an 82-inch DLP screen. 13 individuals with mild-to-moderate manifestations of TBI participated in the study. While standing in front of the screen, the participants interacted with a computer-generated environment by popping bubbles blown by the Octopus. The bubbles followed a specific trajectory. Interception of the bubbles with the left or right hand avatar allowed flexible use of the postural segments for balance maintenance and arm transport. All participants practiced ten 90-s gaming trials during a single session, followed by a retention test. Arm-postural coordination was analysed using principal component analysis. Results As a result of the short-term practice, the participants improved in game performance, arm movement time, and precision. Improvements were achieved mostly by adapting efficient arm-postural coordination strategies. Of the 13 participants, 10 showed an immediate increase in arm forward reach and single-leg stance time.

    Full Text Available Under a strategy to attract diverse audiences, the audiovisual industry has been fragmenting its content based on several criteria, including the gender. In this sense, this research aims to verify if these distinctions are reflected in the children´s content selection in relation with different screens (TV, videogames and the internet. To cope with this research, we selected a quantitative analysis using the technique of the questionnaire that was distributed among students of 6th year primary school, who are between 11 and 12 years to finally access to a sample of 2200 individuals from 77 public and private Galician schools. Thanks to this data, we could corroborate that children choose completely different content according to their gender, excepting internet, media in which their preferences tend to converge.

    To quantify the relationships between youth use of television (TV) and other screen devices, including smartphones and tablets, and obesity risk factors. TV and other screen device use, including smartphones, tablets, computers, and/or videogames, was self-reported by a nationally representative, cross-sectional sample of 24 800 US high school students (2013-2015 Youth Risk Behavior Surveys). Students also reported on health behaviors including sugar-sweetened beverage (SSB) intake, physical activity, sleep, and weight and height. Sex-stratified logistic regression models, adjusting for the sampling design, estimated associations between TV and other screen device use and SSB intake, physical activity, sleep, and obesity. Approximately 20% of participants used other screen devices for ≥5 hours daily. Watching TV ≥5 hours daily was associated with daily SSB consumption (aOR = 2.72, 95% CI: 2.23, 3.32) and obesity (aOR = 1.78, 95% CI: 1.40, 2.27). Using other screen devices ≥5 hours daily was associated with daily SSB consumption (aOR = 1.98, 95% CI: 1.69, 2.32), inadequate physical activity (aOR = 1.94, 95% CI: 1.69, 2.25), and inadequate sleep (aOR = 1.79, 95% CI: 1.54, 2.08). Using smartphones, tablets, computers, and videogames is associated with several obesity risk factors. Although further study is needed, families should be encouraged to limit both TV viewing and newer screen devices. Copyright © 2016 Elsevier Inc. All rights reserved.

    Increasing behavioural evidence suggests that expert video game players (VGPs) show enhanced visual attention and visuospatial abilities, but what underlies these enhancements remains unclear. We administered the Poffenberger paradigm with concurrent electroencephalogram (EEG) recording to assess occipital N1 latencies and interhemispheric transfer time (IHTT) in expert VGPs. Participants comprised 15 right-handed male expert VGPs and 16 non-VGP controls matched for age, handedness, IQ and years of education. Expert VGPs began playing before age 10, had a minimum 8 years experience, and maintained playtime of at least 20 hours per week over the last 6 months. Non-VGPs had little-to-no game play experience (maximum 1.5 years). Participants responded to checkerboard stimuli presented to the left and right visual fields while 128-channel EEG was recorded. Expert VGPs responded significantly more quickly than non-VGPs. Expert VGPs also had significantly earlier occipital N1s in direct visual pathways (the hemisphere contralateral to the visual field in which the stimulus was presented). IHTT was calculated by comparing the latencies of occipital N1 components between hemispheres. No significant between-group differences in electrophysiological estimates of IHTT were found. Shorter N1 latencies may enable expert VGPs to discriminate attended visual stimuli significantly earlier than non-VGPs and contribute to faster responding in visual tasks. As successful video-game play requires precise, time pressured, bimanual motor movements in response to complex visual stimuli, which in this sample began during early childhood, these differences may reflect the experience and training involved during the development of video-game expertise, but training studies are needed to test this prediction.

    The current study assessed the feasibility and effectiveness of a full-body-driven intervention videogame targeted at decreasing attention deficit hyperactivity disorder (ADHD) symptoms, specifically inattention, hyperactivity, impulsivity, and motor deficiency. The game was tested in a Dutch sample (N = 73) of school-aged children with elevated ADHD symptoms. Children assigned to the intervention condition played "Adventurous Dreaming Highflying Dragon," and those in the control condition played a comparable full-body-driven game without ADHD-focused training components. Games were played during six 15-minute sessions. Outcomes were teacher-rated ADHD symptoms and scores on neuropsychological tasks assessing motor skills, impulsivity, and sustained attention. There was some indication of greater improvement in the intervention group in comparison to the control group in terms of teacher-rated ADHD symptoms. Both groups showed equal indication of improvement in fine motor skills, but no change was found in gross motor skills. Additionally, both groups showed a deterioration in number of hits (assessing sustained attention) on the go/no-go task. Last, the intervention group showed a greater increase in false alarms (assessing impulsivity) than the control group. Dragon seems promising as a game-based intervention for children with ADHD. Children who played Dragon improved in several areas with only a short amount of gameplay (1.5 hours in total), and their satisfaction with the game was high. For future research, it is recommended to further inspect Dragon's influence on impulsivity and gross motor skills. Furthermore, it is recommended to disentangle, examine, and evaluate specific properties of videogames that might lead to positive behavioral change.

    Abstract Objective The purpose of this study was to examine whether a correlation existed among the scores of the “Jackie Chan Studio Fitness™ Action Run” active videogame (XaviX®, SSD Company, Ltd., Kusatsu, Japan), the 1-mile run/walk, and Progressive Aerobic Cardiovascular Endurance Run (PACER) aerobic fitness tests of the FITNESSGRAM® (The Cooper Institute, Dallas, TX) in order to provide a potential alternative testing method for days that are not environmentally desirable for outdoor testing. Subjects and Methods Participants were a convenience sample from physical education classes of students between the ages of 10 and 15 years. Participants (n=108) were randomly assigned to one of three groups with the only difference being the order of testing. The tests included the “Jackie Chan Action Run” active videogame, the 1-mile run/walk, and the PACER. Testing occurred on three different days during the physical education class. Rating of perceived exertion (RPE) was reported. Results Significant correlations (r=−0.598 to 0.312) were found among the three aerobic fitness tests administered (Pmile run/walk and the PACER (3.81±1.89, 5.93±1.77, and 5.71±2.14, respectively). Conclusions The results suggest that the “Jackie Chan Action Run” test could be an alternative to the 1-mile run/walk and PACER, allowing physical education teachers to perform aerobic fitness testing in an indoor setting that requires less space. Also, children may be more willing to participate in the “Jackie Chan Action Run” based on the lower RPE. PMID:26193440

    Virtual reality videogames can be used to motivate rehabilitation, and telerehabilitation can be used to improve access to rehabilitation. These uses of technology to improve health outcomes are a burgeoning area of rehabilitation research. So far, there is a lack of reports of long-term outcomes of these types of interventions. The authors report a 15-year-old boy with hemiplegic cerebral palsy and epilepsy because of presumed perinatal stroke who improved his plegic hand function and increased his plegic forearm bone health during a 14-month virtual reality videogame hand telerehabilitation intervention. A total of 14 months after the intervention ended, repeat evaluation demonstrated maintenance of both increased hand function and forearm bone health. The implications of this work for the future of rehabilitation in children with neurological disabilities are discussed in this article. PMID:21383228

    Nintendo(®) (Kyoto, Japan) "Wii™ Sports Boxing" ("Wii Boxing") and Xbox(®) (Microsoft, Redmond, WA) "Kinect(®) Sports Boxing" ("Kinect Boxing") are both boxing simulation videogames that are available for two different active videogame (AVG) systems. Although these AVGs are similar, the style of gameplay required is different (i.e., upper body only versus total body movements) and may alter physical activity intensity and one's preference for playing one game over the other. AVGs that elicit the greatest physiologic challenge and are preferred by users should be identified in an effort to enhance the efficacy of physical activity interventions and programs that include AVGs. The mean heart rate (HRmean) and peak heart rate (HRpeak) for 27 adults (22.7±4.2 years old) were recorded during four 10-minute conditions: seated rest, treadmill walking at 3 miles/hour, "Wii Boxing," and "Kinect Boxing." Upon completion of all four conditions, participants indicated which condition they preferred, and HRmean and HRpeak were calculated as a percentage of age-predicted maximum heart rate to classify physical activity intensity for the three activity conditions (treadmill, "Wii Boxing," and "Kinect Boxing"). "Kinect Boxing" significantly (P<0.001) increased percentage HRmean (64.1±1.6 percent of age-predicted maximum) and percentage HRpeak (76.5±1.9 percent) above all other conditions: Wii HRmean, 53.0±1.2 percent; Wii HRpeak, 61.8±1.5 percent; treadmill HRmean, 52.4±1.2 percent; treadmill HRpeak, 55.2±2.2 percent. Percentage HRpeak for "Kinect Boxing" was great enough to be considered a vigorous-intensity physical activity. There was no difference (P=0.55) in percentage HRmean between "Wii Boxing" and treadmill walking. Participants also preferred "Kinect Boxing" (P<0.001; n=26) to all other conditions ("Wii Boxing," n=1; treadmill n=0). "Kinect Boxing" was the most preferred and the only condition that was physiologically challenging enough to be classified as a

    This study aimed to determine whether Nintendo(®) (Redmond, WA) "Wii Fit™" games can help individuals meet physical activity recommendations. Thirty young healthy volunteers were recruited for this randomized crossover study to evaluate the energy expenditure associated with (1) a 30-minute "Wii Fit Free Run," (2) three 10-minute bouts of "Wii Fit" aerobic games ("Rhythm Boxing," "Super Hula Hoop," and "Advanced Steps"), and (3) 30-minute treadmill running/walking. Energy expenditure was measured by indirect calorimetry using breath-by-breath analyses of O2 consumption and CO2 production. The "Wii Fit" conditions produced a moderate exercise intensity (5.0, 4.1, 3.9, and 3.8 metabolic equivalents [METs] in "Free Run," "Rhythm Boxing," "Super Hula Hoop," and "Advanced Steps"), whereas the treadmill running/walking produced a vigorous exercise intensity (METs=8.0). Based on federal guidelines, an individual could achieve the minimum weekly goal of 500 MET-minutes by playing selected "Wii Fit" aerobics games for 20-26 minutes a day, 5 days a week. Although not as vigorous as the treadmill, active-play videogames such as "Wii Fit" may provide an alternative way to encourage exercise and increase adoption and adherence to the physical activity guidelines.

  1. Therapist Perspectives: Wii Active Videogames Use in Inpatient Settings with People Who Have Had a Brain Injury.

    2014-12-01

    Brain injuries (BIs) are a major public health issue. Clinical experience and literature have identified that it is often challenging to motivate people who have had a BI to engage in repetitive exercises commonly prescribed for rehabilitation. As a result, some therapists include commercial active videogames (AVGs) in their therapy sessions to help make repetitive actions fun and engaging. In this project, we explored how the therapists used commercial AVGs to better understand the major barriers and enablers of use. We interviewed 17 therapists from two rehabilitation hospitals who work with people who have had a BI. After the interviews were transcribed, we identified salient themes. At the time of the interviews, therapists were using only the Nintendo(®) (Kyoto, Japan) Wii™ console. Common therapeutic goals included balance and weight shifting. Several patient factors, such as cognitive and physical abilities, age, and previous gaming experience, were considered important considerations when deciding to use games. Therapists also indicated many desired changes to games, including better control/interface, better feedback, and the ability to adjust timing, challenge, and stimulation levels. When considering therapy-centered game design, the needs of both therapists and patients should be considered. There is a necessary balance to consider in game design: They need to (a) be perceived as fun, (b) meet therapy goals, and (c) address therapists' needs (e.g., adjustability to address a range of patient abilities). Additionally, there is a need for a wide variety of available games to address novelty and personal preferences.

    Positive changes in diet have been observed in research carried out in the United States from the use of "Escape from Diab" (Diab), a health videogame designed to lower the risk of obesity and type 2 diabetes. Whether the American story and characters in Diab might be perceived by Hong Kong Chinese children as interesting has not been explored. This study assessed the acceptability and applicability of Diab among Hong Kong Chinese children, whether the Diab story was understood by them, and whether it had potential to influence them both during the game and afterward. Thirty-four students (21 males, 13 females) 9-12 years of age were included. Upon completion of all the Diab episodes, children completed an immersion scale with 18 items, as well as an individual interview with 10 open-ended questions. Children achieved average immersion after playing Diab with the mean score at 39.1 (standard deviation = 9.0), higher than the median (36) of possible scores (range, 18-54). Four themes using framework analysis emerged from the interviews, including intuitive feelings about the interface, playing experience, perception of the effect of Diab on behavior change, and the applicability of Diab to Hong Kong children. The story and game developed for American children were found acceptable and applicable to Hong Kong Chinese children. The combination of quantitative and qualitative methods confirmed the acceptability and applicability of Diab to Hong Kong Chinese children.

    This article describes the design, development, and implementation feasibility of a purpose-built mobile active videogame (M-AVG) named "Pirate Adventure," which was designed for primary school-aged children to engage in physical activity (PA) and fundamental movement skills (FMS), such as hopping, sidestepping, jumping, or running, in an afterschool setting. The design of "Pirate Adventure" was the result of a collaboration between games designers and health researchers. "Pirate Adventure" was designed and developed using Android(®) (Google, Mountain View, CA) phone sensors to respond to player actions within a playground environment. Using an interactive game framework, players solve clues and complete PA and FMS challenges via sensing the physical world through marked-out key game locations. Fourteen primary school-aged children participated in the feasibility evaluation, which took place in four afternoon sessions. The game was evaluated using Android phone telemetry data and a post-gameplay survey for children on their opinions and enjoyment of the game. The "Pirate Adventure" game design facilitated an enjoyable treasure hunt game (average of 11 minutes of activity per game) with narrative elements supporting children's engagement with movement activities. The majority of children (n=9/13) reported that they would like to play the game again. Combining real world and virtual world content through "Pirate Adventure" was moderately successful, with multiple gameplay sessions occurring. Further implementation feasibility testing, under more controlled conditions, needs to be conducted to assert the benefits of using a M-AVG for children's PA and FMS.

    videogames can give us a valuable and novel insight into the popular culture of our times. What are the main distinctive features used to represent war in military strategy videogames compared to those used in chess? What are the main differences between the most popular videoludic metaphors of construction and traditional puzzles? The aim of this article is to explore questions like these by making a comparative analysis of the underlying meanings of traditional games and popular videogames. The theoretical and methodological framework is based on game history, game design theory and theory of videogame meaning. The findings reveal elements that shed light on the nuances of meaning that distinguish traditional games from popular videogames of the same genre, and show that the analysis model conceived for this study could be of interest for further research. Finally, we reflect on the relationship between the underlying meanings of the videogames analyzed and certain distinctive aspects of contemporary culture.

    Full Text Available A motivação é listada como uma das variáveis afetivas da qual depende o sucesso na aprendizagem. Segundo Dörnyei (2005, a motivação está relacionada a um dos aspectos mais básicos da mente humana, e boa parte dos professores e pesquisadores concordam que a motivação tem papel importante na determinação de sucesso ou fracasso em qualquer situação de aprendizagem. A palavra motivação tem origem no verbo latino movere, que significa mover, sendo definida, então, como o que leva o indivíduo a fazer escolhas, a se engajar em certas atividades e a persistir nessa ação. O surgimento dos videogames nos remete aos Estados Unidos da década de 40. Esses jogos revolucionam a indústria de entretenimento e se proliferaram por todo o mundo, chegando aos aparelhos que conhecemos hoje, modernos, com alta tecnologia e mais, mediadores da aprendizagem de línguas. Este estudo tem por objetivo propor uma leitura dos princípios de aprendizagem de James Paul Gee em relação à aprendizagem por meio de videogames a partir das estratégias motivacionais para aprendizagem de língua estrangeira propostas pelo psicólogo Zóltan Dörnyei. Trata-se de uma tentativa de melhor compreender o papel facilitador para a aprendizagem de línguas inerentes aos videogames aliados ao seu potencial motivacional.

    Active-input videogames could provide a useful conduit for increasing physical activity by improving a child's self-confidence, physical activity enjoyment, and reducing anxiety. Therefore this study evaluated the impact of (a) the removal of home access to traditional electronic games or (b) their replacement with active-input videogames, on child self-perception, enjoyment of physical activity, and electronic game use anxiety. This was a crossover, randomized controlled trial, conducted over a 6-month period in participants' family homes in metropolitan Perth, Australia, from 2007 to 2010. Children 10-12 years old were recruited through school and community media. Of 210 children who were eligible, 74 met inclusion criteria, and 8 withdrew, leaving 66 children (33 girls) for analysis. A counterbalanced randomized order of three conditions sustained for 8 weeks each: No home access to electronic games, home access to traditional electronic games, and home access to active-input electronic games. Perception of self-esteem (Harter's Self Perception Profile for Children), enjoyment of physical activity (Physical Activity Enjoyment Scale questionnaire), and anxiety toward electronic game use (modified Loyd and Gressard Computer Anxiety Subscale) were assessed. Compared with home access to traditional electronic games, neither removal of all electronic games nor replacement with active-input games resulted in any significant change to child self-esteem, enjoyment of physical activity, or anxiety related to electronic games. Although active-input videogames have been shown to be enjoyable in the short term, their ability to impact on psychological outcomes is yet to be established.

    More than 30% of the U.S. population is prehypertensive, and the recommended treatment of lifestyle modification includes increased physical activity. Exercise videogames (EVG) are widely marketed to Americans as a means of increasing fitness. This study aimed to examine EVG among a sample of prehypertensive adults, to determine (1) feasibility and acceptability of EVG for physical activity, and (2) assess changes in (1) estimates of cardiovascular fitness and risk indices, and psychosocial constructs. Participants with prehypertension completed a 12-week program including; 36, 1-hour sessions; supervised EVG program using Nintendo Wii platform and games. Assessments were at baseline and 13 weeks. Paired t-tests were conducted. Fourteen adults (84% female; mean age=53 years; 93% Caucasian; 87% employed) completed the study. The study retention rate was 74% and all participants reported satisfaction and enjoyment in the intervention and using the Wii for exercise. Despite the small sample size, significant improvements were seen in: physical activity minutes (P<0.01), peak heart rate (P=0.02), resting systolic blood pressure (P=0.02), and hip circumference (P=0.03). Significant improvements were also seen in the 36-item short-form survey (SF-36) as for general health (P=0.05), role limitations due to emotional problems (P=0.04), and vitality (P=0.01). Findings support that an EVG program is feasible, acceptable, and promising in promoting benefit to cardiovascular fitness and psychosocial health. These data provide pilot data for the necessary randomized clinical trials to examine efficacy and sustainability of EVG for adult engagement in physical activity for cardiovascular health promotion.

    First experiences in the operating theatre with real patients are always stressful and intimidating for students. We hypothesized that a game-like simulation could improve perceptions and performance of novices. A videogame was developed, combining pictures and short videos, by which students are interactively instructed on acting at the surgical block. Moreover, the game includes detailed descriptive information. After playing, students are given feedback on their performance. A randomized controlled trial was conducted with 132 nursing and medical students with no previous experience in surgery. Sixty two (47.0%) were allocated to a control group (CG) and 70 (53.0%) to an experimental group (EG). Subjects in EG played the game the day prior to their first experience in the theatre; CG had no access to the application. On the day after their experience at surgery, all students filled in a questionnaire in a 7-point Likert format collecting subjective data about their experience in the surgical block. Four constructs related to students' feelings, emotions and attitudes were measured through self-reported subjective scales, i.e. C1: fear to make mistakes, C2: perceived knowledge on how to behave, C3: perceived errors committed, and C4: attitude/behaviour towards patients and staff. The main research question was formulated as follows: do students show differences in constructs C1-C4 by exposure to the game? EG reported statistically significant higher scores on the four aspects measured than CG (pgame-like simulation had a significant positive effect on all the constructs. After their first visit to the theatre, students in EG showed less fear (C1) and also perceived to have committed fewer errors (C3), while they showed higher perceived knowledge (C2) and a more collaborative attitude (C4).

    This article presents the results of interviews conducted with children regarding their cognitive and affective responses toward a narrative and a non-narrative cartoon. The findings will be used to further explore the role of a narrative in motivating continued active videogame play. Twenty children (8-11 years old of mixed gender) watched two cartoons (narrative and non-narrative) and were subsequently interviewed. A thematic matrix was used to analyze the interviews. The narrative cartoon (n = 11) was only slightly preferred compared with the non-narrative one (n = 9), with little difference among the participants. The theme categories identified during the analyses were plot, characters, and suggestions. The fight scenes were mentioned by the children as a likeable aspect of the narrative cartoon. In the non-narrative cartoon, the vast majority (n = 17) liked the information about physical activity that was provided. The children enjoyed the appearance and personalities of the characters in both cartoons. A discrepancy in the data about the fight scenes (narrative cartoon) and characters (both cartoons) was found among the female participants (i.e., some girls did not like the fight and thought the characters were too aggressive). However, most of the children wanted to see more action in the story, an increase in the number of fight scenes (narrative cartoon), or more information about exercise and examples of exercises they could do (non-narrative cartoon). They also suggested adding a game to the non-narrative cartoon, including more characters, and improving the animation in both cartoons. The children preferred the narrative cartoon because of the story and the fight. Some gender differences were found, which further studies should investigate.

    Watching television and playing video game being seated represent sedentary behaviours and increase the risk of weight gain and hypertension. We investigated the acute effects of violent and non-violent video-game playing on blood pressure (BP), appetite perception and food preferences. Forty-eight young, normal-weight men (age: 23.1±1.9 years; body mass index: 22.5±1.9 kg/m(2)) participated in a three-arm, randomized trial. Subjects played a violent video game, a competitive, non-violent video game or watched TV for 1 h. Measurements of BP, stress and appetite perception were recorded before a standardized meal (∼300 kcal) and then repeated every 15 min throughout the intervention. Violent video-game playing was associated with a significant increase in diastolic BP (Δ±s.d.=+7.5±5.8 mm Hg; P=0.04) compared with the other two groups. Subjects playing violent video games felt less full (P=0.02) and reported a tendency towards sweet food consumption. Video games involving violence appear to be associated with significant effects on BP and appetite perceptions compared with non-violent gaming or watching TV.

    Flavored tobacco products have been shown to appeal to youth, however tobacco control strategies have traditionally not focused on these products. To inform the adaptation of an existing videogame to focus on the prevention of flavored tobacco product use, this study explored adolescents' perceptions, beliefs, and social norms surrounding these products, including flavored e-cigarettes. We conducted and analyzed transcripts from seven focus groups with 11-17-year-old adolescents (n = 33) from after-school programs in CT and CA in 2016. Participants discussed flavored tobacco product beliefs and experiences, and how these compared to traditional cigarettes. Thematic analysis of transcripts revealed that participants could name flavors in tobacco products, even though few discussed first-hand experience with the products. Most groups perceived that flavored tobacco product and flavored e-cigarette use facilitated peer approval and acceptance. All groups discussed how youth could easily access flavored tobacco products, including e-cigarettes. Flavoring was a salient aspect of e-cigarette advertisements; however the groups did not recall exposure to other types of flavored tobacco product counter-marketing. These data can help inform the development of tobacco control strategies, novel interventions (such as videogames), and future FDA efforts to prevent adolescent tobacco product use through education and risk communication.

    Full Text Available Starting from the thesis that ''history is written by the winners”, ''mainstream'' history can be under¬stood as the revised and politically instrumentalized means of a certain nation's ''cultural'' memory, which some consider to be a ''history of selective memo¬ri¬zation and selective forgetfulness''. Most approaches in con¬temporary Croatian historiography which are focu¬sed on the historical periods of monarchist and socialist Yugoslavia use national-level themes as their starting point. A similar preoccupation is also present in those historiographical approaches which are focused on the problems of analyzing and understanding how collective memories are constructed. However, our aim here is to move from the ''big'' themes to a ''small'' (local setting. In this context, Samobor, a small Croatian urban centre, is going to serve us as the basis for analyzing in which way two Yugoslav rulers – King Alexander Karađorđević and Marshal Josip Broz Tito – were perceived on the local level. By analyzing the relevant archival sources as well as contemporary periodicals, we seek to un¬der¬stand the ways in which local authorities and elites, from their position of social power and status, received the mentioned rulers during their visits, and in which ways did they honour and commemorate these high-profile guests. Through this analysis, we hope to gain a better understanding of the process of the creation of local social memory, the constitution of memorial and cul¬tural patterns, and their key cultural elements and me¬anings, which are often torn apart during periods of social and political upheaval, only to be reconstituted by recombining the same key cultural and social elements while simultaneously encompassing new actors. In other words, the focus of our analysis will be on tracing the collective memory of the population of Samobor to¬wards two ''great leaders''.

    Full Text Available Immersion is constantly being broken in video games via the intrusion of mechanics and features that cause no end of distraction, breaking the player’s engagement in both the game’s narrative and in the gameplay. Yet these breaks are an integral part of games, whether through loading, saving or any other mechanical system that detracts from the playing the core game. These aren’t analysed as thoroughly as they could be in current game academia. However Bertolt Brecht’s “Verfremdungseffekt”, or distancing effect, provides a much needed foundation in the analysis of these sections within games that provoke a feeling of alienation.

    Describe the clinical use of virtual reality (VR)/active videogaming (AVG) by physical therapists (PTs) and occupational therapists (OTs) in Canada, identify usage barriers and facilitators, evaluate factors that predict intention to use VR/AVGs, and determine therapists' learning needs. Cross-sectional survey. Online survey of therapists in Canada who were members of 1 of 26 professional PT or OT colleges or associations using the Assessing Determinants Of Prospective Take-up of Virtual Reality (ADOPT-VR2) Instrument. We received 1071 (506 PTs, 562 OTs, 3 dual-trained) responses. Forty-six percent had clinical VR/AVG experience; only 12% reported current use, with the Wii being the most clinically accessible (41%) system. Therapists used VR/AVGs primarily in rehabilitation (32%) and hospital (29%) settings, preferentially targeting balance (39.3%) and physical activity (19.8%) outcomes. Stroke (25.8%), brain injury (15.3%), musculoskeletal (14.9%), and cerebral palsy (10.5%) populations were most frequently treated. Therapists with VR/AVG experience rated all ADOPT-VR2 constructs more highly than did those without experience (P learning more. Understanding use, predictors of use, and learning needs is essential for developing knowledge translation initiatives to support clinical integration of VR/AVGs. Results of this first national survey will inform the creation of resources to support therapists in this field.

Materials and methods We conducted a cross-sectional study with a sample of 524 5th to 8th grade students (278 boys and 246 girls, enrolled in all five urban elementary schools in the municipality of Bauru (SP, aged between 10 and 14 years old. Sociodemographic data, sedentary activities – time spent on TV and computer and/or videogame - and level of physical activity - was collected through a Physical Activity Questionnaire for Children (PAQ-C. Results The results showed that the prevalence of localized pain in the neck/shoulders was of 30.1% for boys and girls. It was also found that there is a predominance of onset of pain reported in neck/shoulders in boys related to the frequency and amount of hours a day watching TV and hours on the computer, whereas in girls the association was with frequency and amount of hours they watch TV daily. Conclusions It can be concluded that the pain in the neck/shoulders are common in children and that understanding the relationship between variables enables valuable elements of measures aimed at maintaining, improving and promoting the welfare of students.

    Many women over 65 years of age suffer from mixed urinary incontinence (MUI) and executive function (EF) deficits. Both incontinence and EF declines increase fall risk. The current study assessed EF and dual-task gait after a multicomponent intervention that combined pelvic floor muscle (PFM) training and videogame dancing (VGD). Baseline (Pre1), pretraining (Pre2), and post-training (Post) neuropsychological and dual-task gait assessments were completed by 23 women (mean age, 70.4 years) with MUI. During the dual-task, participants walked and performed an auditory n-back task. From Pre2 to Post, all women completed 12 weeks of combined PFM and VGD training. After training (Pre2 to Post), the number of errors in the Inhibition/Switch Stroop condition decreased significantly, the Trail Making Test difference score improved marginally, and the number of n-back errors during dual-task gait significantly decreased. A subgroup analysis based on continence improvements (pad test) revealed that only those subjects who improved in the pad test had significantly reduced numbers of n-back errors during dual-task gait. The results of this study suggest that a multicomponent intervention can improve EFs and the dual-task gait of older women with MUI. Future research is needed to determine if the training-induced improvements in these factors reduce fall risk.

    Low back pain is a significant problem for school-aged athletes. Although some risk factors relating to sports activities have been reported, the effect of lifestyles on low back pain in school-aged athletes is not clear. The purpose of this study was to elucidate the association between lifestyles, such as wake-up time, bedtime, sleeping time, and TV-viewing or video-game-playing time per day and low back pain of school-aged athletes. A cross-sectional study was conducted with school-aged athletes (aged 6-15 years, n = 6441) using a self-reported questionnaire and multivariate logistic regression models were used for analyses. Variables considered in the models were gender, age, body mass index, team levels, number of days in practice per week, number of hours in practice per day, and lifestyles. The frequency of low back pain was 5.0% (n = 322). Late bedtime, short sleeping time, and long video-game-playing time per day were significantly associated with low back pain. There was no significant association between low back pain and wake-up time or TV-viewing time per day. Unhealthy life-style choices, such as late bedtimes, short sleeping time, and longtime video-game playing, were associated with low back pain in school-aged athletes.

    Several studies have highlighted the implications of impulsivity and novelty seeking for both the maintenance and the process of recovery from bulimia nervosa (BN). Cognitive behavioral therapy (CBT) is the treatment of choice for BN, but for some cases, this treatment alone might not be sufficient for reducing the high levels of impulsivity. The paper presents a case report of a patient with BN, examining the effectiveness of using a videogame (VG; Playmancer) as an additional intervention designed to address impulsivity. Psychometric and neuropsychological measures were collected at baseline. After this assessment, Playmancer was applied prior to CBT, following an "A-B-A-C-A" single case experimental design. Impulsivity levels were assessed with the Conner's Continuous Performance Test II (CPT-II). After the Playmancer treatment, the patient started CBT, and the levels of impulsivity were recorded again. Finally, psychometric and neuropsychological measures were collected after treatment. Weekly frequency of binges and vomiting were also recorded during the entire procedure. After the VG intervention, psychometric measures such as anxiety levels, impulsivity and novelty seeking decreased. Regarding the neuropsychological measures, impulsivity levels (measured with the CPT-II) progressively decreased throughout the intervention, and an improvement in decision making capacities was observed. Furthermore, the frequency of binges also decreased during and after the VG intervention. This case report suggests that using the Playmancer VG to reduce impulsivity prior to CBT may enhance the final results of the treatment for BN.

    Full Text Available OBJETIVO: Com a inclusão das novas tecnologias contemporâneas, a Internet e os jogos eletrônicos tornaram-se ferramentas de uso amplo e irrestrito, transformando-se em um dos maiores fenômenos mundiais da última década. Diversas pesquisas atestam os benefícios desses recursos, mas seu uso sadio e adaptativo progressivamente deu lugar ao abuso e à falta de controle ao criar severos impactos na vida cotidiana de milhões de usuários. O objetivo deste estudo foi revisar de forma sistemática os artigos que examinam a dependência de Internet e jogos eletrônicos na população geral. Almejamos, portanto, avaliar a evolução destes conceitos no decorrer da última década, assim como contribuir para a melhor compreensão do quadro e suas comorbidades. MÉTODO: Foi feita uma revisão sistemática da literatura através do MedLine, Lilacs, SciELO e Cochrane usando-se como parâmetro os termos: "Internet addiction", pathological "Internet use", "problematic Internet use", "Internet abuse", "videogame", "computer games" e "electronic games". A busca eletrônica foi feita até dezembro de 2007. DISCUSSÃO: Estudos realizados em diferentes países apontam para prevalências ainda muito diversas, o que provavelmente se deve à falta de consenso e ao uso de diferentes denominações, dando margem à adoção de distintos critérios diagnósticos. Muitos pacientes que relatam o uso abusivo e dependência passam a apresentar prejuízos significativos na vida profissional, acadêmica (escolar, social e familiar. CONCLUSÕES: São necessárias novas investigações para determinar se esse uso abusivo de Internet e de jogos eletrônicos pode ser compreendido como uma das mais novas classificações psiquiátricas do século XXI ou apenas substratos de outros transtornos.OBJECTIVE: With the introduction of the new technologies to our daily lives, the Internet and electronic games have become widely and unrestrictedly used tools and one of the major

    The purpose of the study was to compare the effects of a Kinect active videogame (AVG) and the Sports, Play, and Active Recreation for Kids (SPARK) intervention in improving children's health-related fitness and physical activity (PA) enjoyment. A total of 65 students from both third and fourth grade in a rural elementary school participated in the study. The third graders (N = 29, mean age = 9.1 years, 10 boys, mean body mass index [BMI] = 20.1) were assigned to a SPARK physical education group, while the fourth graders (N = 36, mean age = 10.2 years, 15 boys, mean BMI = 20.3) were enrolled in the Kinect AVG group. The intervention lasted for 6 weeks, with each week including three practice sessions (∼40 minutes per session). All participants were measured on their health-related fitness by testing their performance in the 15-m Progressive Aerobic Cardiovascular Endurance Run (PACER), curl-ups, and push-ups both before and after the interventions. Participants' PA enjoyment was measured immediately after the first and last session's practice. Various ANCOVA tests were conducted to analyze the intervention effects on the changes of health-related fitness performances and enjoyment while controlling for baseline values, gender, and BMI. Various MANOVA tests were used to examine the intervention effects on PA levels during three practice sessions. Participants in AVG group had greater improvement in 15-m PACER test (P strategy in improving children's cardiorespiratory fitness while maintaining PA enjoyment.

    Full Text Available Videogames are showing a growing degree of social implantation, mainly in more developed countries. This circumstance is demonstrated because their influence is extended not only to younger groups but to all the society too. Altogether with innovations like television, internet o mobile telephony, videogames are contributing to change the traditional pattern of accessing and transmission of knowledge, that passes from reading written texts to viewing audiovisual and multimedia contents. This article, based in a research referred to more than 900 people, analyzes which is the degree of its penetration in Spain between older than 35 years and which are the habits of use of this technology between this group. In order to do this, the article exams items like habits of playing by ages, daily dedication, range of playing during day and week and aspects more valued in videogames.Los videojuegos demuestran un creciente grado de implantación social, particularmente perceptible en los países más desarrollados. Tal circunstancia se manifiesta porque su influencia ya no se limita exclusivamente a los grupos poblacionales más jóvenes sino que actualmente alcanzan la totalidad de la sociedad. Conjuntamente con innovaciones como la televisión, internet o la telefonía móvil, los videojuegos están contribuyendo a modificar el tradicional proceso de acceso y transmisión del conocimiento, que pasa de basarse en la lectura del texto escrito a la contemplación de contenidos audiovisuales y multimedia. Este artículo, que se basa en una investigación planteada a más de 900 individuos, analiza cuál es su grado de implantación en España entre las personas mayores de 35 años y cuáles son los hábitos de uso de esta tecnología entre dicho grupo poblacional.

El aprendizaje permanente incluye las mismas como claves de la formación de la persona y sobre todo, como elemento que va a contribuir a su inserción en una sociedad dinámica y cambiante. Tras analizar dichas dimensiones, las mismas serán reflejadas en el videojuego denominado «Dragon Age: Orígenes», galardonado con el premio juego de rol del año en el año 2009. El desarrollo de la competencia digital conlleva una nueva alfabetización y en la misma es preciso hallar recursos motivadores para que dicha adquisición sea a la vez una cuestión lúdica y formativa. Otro aspecto relevante que será tratado en el texto tiene que ver con la multimodalidad textual (Kress & Van Leeuwen, 2001, sobre todo con los nuevos formatos narrativos. Este hecho supone un importante avance social ya que las formas de lectura varían apareciendo formas distintas más motivadoras para el usuario pero no por ello poseen menor calidad. Éste es el caso de «Dragon Age: Orígenes», un juego de rol basado en la fantasía heroica ubicado en un mundo novedoso. Dicho juego se convierte en una excelente historia para ser leída y experimentada.The approach of this article is centered on the concepts of digital competence and new narrative formats. We aim to apply these dimensions to the videogame «Dragon Age Origins», winner of the 2009 videogame of the year award. Its features - plot, characters and interactivity – make it ideal reading material in other formats and are highly motivational for young people. The development of digital competence signifies new literacy, and it is necessary to find new stimulating resources that combine the fun and formative dimensions. Equally relevant are multimodal texts (Kress & Van Leeuwen, 2001, especially new narrative formats that imply social progress, as the ways of reading are different. The texts have

    Background To address the need for risk behavior reduction and HIV prevention interventions that capture adolescents “where they live,” we created a tablet-based videogame to teach skills and knowledge and influence psychosocial antecedents for decreasing risk and preventing HIV infection in minority youth in schools, after-school programs, and summer camps. Methods We developed PlayForward: Elm City Stories over a 2-year period, working with researchers, commercial game designers, and staff and teens from community programs. The videogame PlayForward provides an interactive world where players, using an avatar, “travel” through time, facing challenges such as peer pressure to drink alcohol or engage in risky sexual behaviors. Players experience how their choices affect their future and then are able to go back in time and change their choices, creating different outcomes. A randomized controlled trial was designed to evaluate the efficacy of PlayForward. Participants were randomly assigned to play PlayForward or a set of attention/time control games on a tablet at their community-based program. Assessment data were collected during face-to-face study visits and entered into a web-based platform and unique real-time “in-game” PlayForward data were collected as players engaged in the game. The innovative methods of this randomized controlled trial are described. We highlight the logistical issues of conducting a large-scale trial using mobile technology such as the iPad®, and collecting, transferring, and storing large amounts of in-game data. We outline the methods used to analyze the in-game data alone and in conjunction with standardized assessment data to establish correlations between behaviors during gameplay and those reported in real life. We also describe the use of the in-game data as a measure of fidelity to the intervention. Results In total, 333 boys and girls, aged 11–14 years, were randomized over a 14-month period: 166 were assigned to

Com exceção do mercado japonês, em que há uma preferência nítida para os consoles locais, nos demais existe equilíbrio na participação de mercado, o que demonstra que os mercados dos Estados Unidos e da Europa podem ser considerados mais contrabalançados. Observando a eficiência dos mercados anualmente, percebe-se um padrão de eficiência no mercado europeu, que se manteve como bechmark para todos os anos de estudo. Dessa forma, considerando a eficiência total, o mercado europeu é eficiente com grau de eficiência máximo (100%, tendo o americano (62,49% e o japonês (34,87% como antecessores, respectivamente. As diferenças da eficiência entre os mercados podem ser evidenciadas pelos impactos que a sétima geração de consoles provoca em questões econômicas e culturais.

    Full Text Available Abstract Aim: to analyze the pattern and trends of use of screen-based devices and associated factors from two surveys conducted on public high school students in Caruaru-PE. Methods: two representative school-based cross-sectional surveys conducted in 2007 (n=600 and 2012 (n=715 on high school students (15-20 years old. The time of exposure to television (TV and computer/videogames PC/VG was obtained through a validated questionnaire, and ≥3 hours/day was considered as being excessive exposure. The independent variables were socioeconomic status, school related, and physical activity. Crude and adjusted binary logistic regression were employed to examine the factors associated with screen time. The statistical significance was set at p<0.05. Results: There was a significant reduction in TV time on weekdays and total weekly, but no change in the prevalence of excessive exposure. The proportion of exposure to PC/VG of ≥3 hours/day increased 182.5% on weekdays and 69.5% on weekends (p <0.05. In 2007, being physically active was the only protection factor for excessive exposure to total screen time. In 2012, girls presented less chance of excessive exposure to all screen-based devices and total screen time. Other protective factors were studying at night and being physically active (PC/VG time, while residing in an urban area [OR 5.03(2.77-7.41] and having higher family income [OR 1.55(1.04-2.30] were risk factors. Conclusion: Significant and important changes in the time trends and pattern of use PC/VG were observed during the interval of 5 years. This rapid increase could be associated with increased family income and improved access to these devices, driven by technological developments.

    Ongoing physical activity is important for maintaining the functional level of individuals with chronic stroke. Video games in a group setting might be a cost-effective way for providing mobility and preventing physical inactivity. This study explores the experiences and perceptions of individuals with chronic stroke who participated in a novel community-based video-game group intervention and their therapists. A qualitative study, nested in a randomized controlled trial, was conducted using semistructured interviews with eight individuals with chronic stroke (four men and four women) ages 29 to 69 and a focus group of their three occupational therapists, following a video-game intervention. Data were analyzed using content analysis. Three main categories were identified by the study participants: (a) using video games, (b) the group/team experience, and (c) intervention outcomes/evolving understandings following the intervention. Playing video games was perceived not as treatment but as a motivating tool to facilitate whole-body movement. Therefore, this intervention might be suitable to be used in the community for ongoing intervention.

    Full Text Available Pathological gaming is an emerging and poorly understood problem. Impulsivity is commonly impaired in disorders of behavioural and substance addiction, hence we sought to systematically investigate the different subtypes of decisional and motor impulsivity in a well-defined pathological gaming cohort.Fifty-two pathological gaming subjects and age-, gender- and IQ-matched healthy volunteers were tested on decisional impulsivity (Information Sampling Task testing reflection impulsivity and delay discounting questionnaire testing impulsive choice, and motor impulsivity (Stop Signal Task testing motor response inhibition, and the premature responding task. We used stringent diagnostic criteria highlighting functional impairment.In the Information Sampling Task, pathological gaming participants sampled less evidence prior to making a decision and scored fewer points compared with healthy volunteers. Gaming severity was also negatively correlated with evidence gathered and positively correlated with sampling error and points acquired. In the delay discounting task, pathological gamers made more impulsive choices, preferring smaller immediate over larger delayed rewards. Pathological gamers made more premature responses related to comorbid nicotine use. Greater number of hours played also correlated with a Motivational Index. Greater frequency of role playing games was associated with impaired motor response inhibition and strategy games with faster Go reaction time.We show that pathological gaming is associated with impaired decisional impulsivity with negative consequences in task performance. Decisional impulsivity may be a potential target in therapeutic management.

    The 16-day composite MODIS vegetation indices (VIs) at 500-m resolution for the period between 2000 to 2007 were seasonally averaged on the basis of the estimated distribution of 16 potential natural terrestrial ecosystems (NTEs) across Turkey. Graphical and statistical analyses of the time-series VIs for the NTEs spatially disaggregated in terms of biogeoclimate zones and land cover types included descriptive statistics, correlations, discrete Fourier transform (DFT), time-series decomposition, and simple linear regression (SLR) models. Our spatio-temporal analyses revealed that both MODIS VIs, on average, depicted similar seasonal variations for the NTEs, with the NDVI values having higher mean and SD values. The seasonal VIs were most correlated in decreasing order for: barren/sparsely vegetated land > grassland > shrubland/woodland > forest; (sub)nival > warm temperate > alpine > cool temperate > boreal = Mediterranean; and summer > spring > autumn > winter. Most pronounced differences between the MODIS VI responses over Turkey occurred in boreal and Mediterranean climate zones and forests, and in winter (the senescence phase of the growing season). Our results showed the potential of the time-series MODIS VI datasets in the estimation and monitoring of seasonal and interannual ecosystem dynamics over Turkey that needs to be further improved and refined through systematic and extensive field measurements and validations across various biomes.

    Full Text Available (italijanski Quest’articolo tratta l’analisi del progetto della chiesa monastica dedicata a S. Giorgio (1170/71, situata nei pressi di Novi Pazar, fondazione del gran giuppano Stefan Nemanja. Il metodo dell’ autore richiedeva un cambio dei canoni di lettura di quelli applicati a S. Nicola a Toplica, la fondazione precedente della stessa committenza, per poter comprendere l’organizzazione della pianta di S. Giorgio, progettazione del suo spazio interno, modellazione del suo volume e realizzazione da parte dallo stesso costruttore. Secondo l’autore l’interno della chiesa sia stato congeniato attraverso le due assialità - longitudinale e trasversale configurando una nuova concezione dello spazio, cui contribuisce, anche notevole altezza. La pianta della chiesa presenta una superficie quadrata in cui centro è posizionata l’aula centrale, coperta da cupola. L’aula centrale è il luogo che ammetteva due diverse assialità (per questo volutamente rettangolare in pianta, e aveva perseguito senso della verticalità che ha dato movimento all’intera volumetria centrale offrendo luogo alla terza asse, quella verticale. Le simili misure di queste tre assi (13.8 m, 14.24 m, 14.3 m hanno fatto pensare all’autore che la genesi progettuale sottostante sia una forma cubica, la cui base sono tre assi avvalorati dalle prospettive conseguenti: una parte dall’ingresso ad ovest toccando il culmine dell’abside centrale; questo asse è tagliato ortogonalmente dal secondo che unisce i due portali laterali; il terzo asse parte dal centro geometrico d’incontro delle prospettive a terra salendo al sommo della cupola. L’analisi ha mostrato anche l’ingresso principale era il luogo delle generatrici visive: una ortogonale (l’ase longitudinale e due oblique (che si creano lungo i fuochi dell’elisse centrale che immettevano nelle abside laterali.

    This presentation addresses the fundamental question of how much charging infrastructure is needed in the United States to support PEVs. It complements ongoing EVSE initiatives by providing a comprehensive analysis of national PEV charging infrastructure requirements. The result is a quantitative estimate for a U.S. network of non-residential (public and workplace) EVSE that would be needed to support broader PEV adoption. The analysis provides guidance to public and private stakeholders who are seeking to provide nationwide charging coverage, improve the EVSE business case by maximizing station utilization, and promote effective use of private/public infrastructure investments.

Aerobic capacity improvement after a 6-week intervention between AVG types was also compared. Twenty participants, after baseline assessments, were randomized into one of three parallel groups: structured AVG (n= 6, unstructured AVG (n= 7 and a control group (n= 7. Participants played their respective AVG 3 times a week for 6-weeks (30 minutes-session. The control group maintained normal activities. Both structured and unstructured AVG improved peak workload after four weeks but only the structured group maintained this improvement through week five and six. Aerobic capacity improved in the unstructured (Pre: 36.0 ± 5.2ml.kg.min-¹,Post: 39.7 ± 4.9ml.kg.min-¹, p = .038 and structured AVG (Pre: 39.0 ± 5.9ml.kg.min-¹,Post: 47.8 ± 4.3ml.kg.min-¹, p = .006 groups. Structured AVG provide greater health benefits to aerobic capacity and peak workload in young sedentary but otherwise healthy males relative to unstructured AVG.

  20. Allen Newell's Program of Research: The Video-Game Test.

    Science.gov (United States)

    Gobet, Fernand

    2017-04-01

    Newell (1973) argued that progress in psychology was slow because research focused on experiments trying to answer binary questions, such as serial versus parallel processing. In addition, not enough attention was paid to the strategies used by participants, and there was a lack of theories implemented as computer models offering sufficient precision for being tested rigorously. He proposed a three-headed research program: to develop computational models able to carry out the task they aimed to explain; to study one complex task in detail, such as chess; and to build computational models that can account for multiple tasks. This article assesses the extent to which the papers in this issue advance Newell's program. While half of the papers devote much attention to strategies, several papers still average across them, a capital sin according to Newell. The three courses of action he proposed were not popular in these papers: Only two papers used computational models, with no model being both able to carry out the task and to account for human data; there was no systematic analysis of a specific video game; and no paper proposed a computational model accounting for human data in several tasks. It is concluded that, while they use sophisticated methods of analysis and discuss interesting results, overall these papers contribute only little to Newell's program of research. In this respect, they reflect the current state of psychology and cognitive science. This is a shame, as Newell's ideas might help address the current crisis of lack of replication and fraud in psychology. Copyright © 2017 The Author.

    Full Text Available In this paper, we propose a method for automatically detecting the times during which game players exhibit specific behavior, such as when players commonly show excitement, concentration, immersion, and surprise. The proposed method detects such outlying behavior based on the game players’ characteristics. These characteristics are captured non-invasively in a general game environment. In this paper, cameras were used to analyze observed data such as facial expressions and player movements. Moreover, multimodal data from the game players (i.e., data regarding adjustments to the volume and the use of the keyboard and mouse was used to analyze high-dimensional game-player data. A support vector machine was used to efficiently detect outlying behaviors. We verified the effectiveness of the proposed method using games from several genres. The recall rate of the outlying behavior pre-identified by industry experts was approximately 70%. The proposed method can also be used for feedback analysis of various interactive content provided in PC environments.

    Evidence shows that internet-based self-help interventions are effective in reducing symptoms for a wide range of mental disorders. To date, online interventions treating psychotic disorders have been scarce, even though psychosis is among the most burdensome disorders worldwide. Furthermore, the implementation of cognitive-behavioral therapy (CBT) for psychosis in routine health care is challenging. Internet-based interventions could narrow this treatment gap. Thus, a comprehensive CBT-based online self-help intervention for people with psychosis has been developed. The aim of this study is the evaluation of the feasibility and efficacy of the intervention compared with a waiting list control group. The intervention includes modules on delusion, voice hearing, social competence, mindfulness, and seven other domains. Participants are guided through the program by a personal moderator. Usage can be amended by an optional smartphone app. In this randomized controlled trial, participants are allocated to a waiting list or an intervention of eight weeks. Change in positive psychotic symptoms of both groups will be compared (primary outcome) and predictors of treatment effects will be assessed. To our knowledge, this project is one of the first large-scale investigations of an internet-based intervention for people with psychosis. It may thus be a further step to broaden treatment options for people suffering from this disorder. NCT02974400 (clinicaltrials.gov), date of registration: November 28th 2016.

    Full Text Available There are numerous pedagogues who look at new media with interest (Maragliano 2003; Rivoltella 2006;, paying attention also to the world of computer games and, particularly, to the so-called field of edutainment. The educational, cognitive and metacognitive implications of the sophisticated technology devices involved and their characteristics of creativity, socialisation, practicality and engagement, already recognised by experts in the field, qualify these devices to be considered interesting tools for playing and laboratory learning. They should be used to support the traditional didactic and educational activities in order to outline a new idea of laboratory and school.

    Full Text Available Although scientific literature, since long time, underlines the importance of storytelling and games as essential cognitive and educational moments, current studies and researches are largely resting over a separate analysis of games and storytelling, establishing a hierarchy among them which crowns one or the other likewise from time to time. It is therefore necessary developing and tuning up methods and educational model that will allow us to develop the natural attitude of human mind to place all information inside one context and one set.

    Directory of Open Access Journals (Sweden)

    Full Text Available Anxiety in children undergoing surgery is characterized by feelings of tension, apprehension, nervousness and fear which may manifest differently. Postoperative behavioural changes such as nocturnal enuresis, feeding disorders, apathy, and sleep disturbances may stem from postoperative anxiety. Some Authors pointed out that over 60% of children undergoing surgery are prone to developing behavioural alterations 2 weeks after surgery. Variables such as age, temperament and anxiety both in children and parents are considered predictors of such changes.1 Studies were published describing how psycho-behavioural interventions based on play, learning and entertainment in preparing children for surgery, may reduce preoperative anxiety. Clown-therapy is applied in the most important paediatric facilities and has proved to diminish children’s emotional distress and sufferance, as well as consumption of both analgesics and sedatives and to facilitate the achievement of therapeutic goals. The aim of our study was to evaluate the efficacy of clown-therapy during the child’s hospital stay, with a view to optimizing treatment and care, preventing behavioural alterations and enhancing the child’s overall life quality.

    Anxiety in children undergoing surgery is characterized by feelings of tension, apprehension, nervousness and fear which may manifest differently. Postoperative behavioural changes such as nocturnal enuresis, feeding disorders, apathy, and sleep disturbances may stem from postoperative anxiety. Some Authors pointed out that over 60% of children undergoing surgery are prone to developing behavioural alterations 2 weeks after surgery. Variables such as age, temperament and anxiety both in children and parents are considered predictors of such changes.1 Studies were published describing how psycho-behavioural interventions based on play, learning and entertainment in preparing children for surgery, may reduce preoperative anxiety. Clown-therapy is applied in the most important paediatric facilities and has proved to diminish children's emotional distress and sufferance, as well as consumption of both analgesics and sedatives and to facilitate the achievement of therapeutic goals. The aim of our study was to evaluate the efficacy of clown-therapy during the child's hospital stay, with a view to optimizing treatment and care, preventing behavioural alterations and enhancing the child's overall life quality.

    Drawing on game-design principles and an underlying situated theoretical perspective, we developed and researched a 3D game-based curriculum designed to teach water quality concepts. We compared undergraduate student dyads assigned randomly to four different instructional design conditions where the content had increasingly level of contextualization: (a) expository textbook condition, (b) simplistic framing condition, (c) immersive world condition, and (d) a single-user immersive world condition. Results indicated that the immersive-world dyad and immersive-world single user conditions performed significantly better than the electronic textbook group on standardized items. The immersive-world dyad condition also performed significantly better than either the expository textbook or the descriptive framing condition on a performance-based transfer task, and performed significantly better than the expository textbook condition on standardized test items. Implications for science education, and consistent with the goals of this special issue, are that immersive game-based learning environments provide a powerful new form of curriculum for teaching and learning science.

    The aim of this study was to determine the prevalence of headache in adolescents and its association with excessive use of electronic devices and games. The sample comprised 954 adolescents of both sexes (14 to 19 years) who answered a questionnaire about use of computers and electronic games, presence of headache and physical activity. The binary and multinomial logistic regression, with significance level of 5% was used for inferential analysis. The prevalence of headache was 80.6%. The excessive use of electronics devices proved to be a risk factor (OR = 1.21) for headache. Subjects aged between 14 and 16 years were less likely to report headache (OR = 0.64). Regarding classification, 17.9% of adolescents had tension-type headache, 19.3% had migraine and 43.4% other types of headache. The adolescents aged form 14 to 16 years had lower chance (OR ≤ 0.68) to report the tension-type headache and other types of headache. The excessive use of digital equipment, electronic games and attending the third year of high school proved to be risk factors for migraine-type development (OR ≥ 1.84). There was a high prevalence of headache in adolescents and high-time use of electronic devices. We observed an association between excessive use of electronic devices and the presence of headache, and this habit is considered a risk factor, especially for the development of migraine-type.

    2014-02-01

    Blocking and shadowing is one of the key effects in designing and evaluating a thermal central receiver solar tower plant. Therefore it is convenient to develop efficient algorithms to compute the area of an heliostat blocked or shadowed by the rest of the field. In this paper we explore the possibility of using very efficient clipping algorithms developed for the video game and imaging industry to compute the blocking and shadowing efficiency of a solar thermal plant layout. We propose an algorithm valid for arbitrary position, orientation and size of the heliostats. This algorithm turns out to be very accurate, free of assumptions and fast. We show the feasibility of the use of this algorithm to the optimization of a solar plant by studying a couple of examples in detail.

    2010-10-01

    Until recently, there has been very little naturalistic study of what gaming experiences are like, and how gaming fits into people's lives. Using a recently developed structural characteristic taxonomy of video games, this study examined the psycho-structural elements of computer games that motivate gamers to play them. Using Q-Sort methodology, 40 gamers participated in an online Q-sort task. Results identified six distinct types of gamers based on the factors generated: (a) story-driven solo gamers; (b) social gamers; (c) solo limited gamers; (d) hardcore online gamers; (e) solo control/identity gamers; and (f ) casual gamers. These gaming types are discussed, and a brief evaluation of similar and unique elements of the different types of gamer is also offered. The current study shows Q-methodology to be a relevant and applicable method in the psychological research of gaming.

    Our aim was to describe experiences of using Nintendo Wii Fit™ for balance exercise, from the perspectives of patients with multiple sclerosis (MS) and their physiotherapists (PT). Individual interviews with 15 patients with MS were conducted, recruited from a multi-centre study investigating the effects of balance exercising using Wii Fit. We also conducted a single focus group interview with nine PT involved in the study. The interviews were audio-recorded, transcribed, and analysed using content analysis. Both patients and PT said that exercising with Wii Fit games was fun, and that it challenged the patients' physical and cognitive capacities. The competitive content in the games provided motivation to continue playing. Patients and PT reported improved body control and, more importantly, positive effects on balance and walking in daily life. The PT regarded Wii training as an effective alternative to other balance training, but some felt unsure in how to manage the video game. The patients regarded Wii training as a possible home training solution. Patients with MS and their PT considered Wii Fit exercises to be fun, challenging, and self-motivating. Exercising with Wii games can address balance impairments in MS, and can be performed at home as well as in rehabilitation settings. Implications for Rehabilitation Nintendo Wii Fit™ can be used as a fun and challenging way to perform balance exercises. The competitive content embedded in the games triggers continued playing and exercising. The positive effect on balance control can improve standing and walking in everyday activities.

    2009-04-01

    Full Text Available Thus far, the bulk of effects research on violent video games demon-strates troubling correlations between playing violent video games and increases in (or primers for aggressive behavior, which suggests that overall, violent video games may be detrimental to society. However, there may be significant weaknesses in this body of research, concerning not only methodological issues such as study design and the ways in which ‘aggression’ or ‘violence’ are conceptualized, but also containing fundamental misunderstandings of games as text, apparatus, or cultural artifact. Because these studies may not have a sophisticated enough un-derstanding of games as objects or gaming as an activity, we must there-fore reconsider the conclusions and implications thus far arrived at in this research and look for new ways forward for assessing violence in/and video games.

    Recent studies on video game playing have uncovered a wide range of measurable physiological effects on the organism, such as increases in cardiovascular activity and breathing responses. However, the exact source of these effects remains unclear. Given the well-known effects of sound on physiological activity, especially those of noise and of music, and on the secretion of the stress hormone cortisol in particular, we hypothesized that music may be a major source of stress during video game playing. We thus examined the effect of built-in music on cortisol secretion as a consequence of video game playing. Players were assigned quasi-randomly to either a Music or a Silence condition. Four saliva samples were taken, that is, after practice (T1), immediately after having played for 10 minutes (T2), 15 minutes after the end of the experiment (T3), and 30 minutes after the end of the experiment (T4). The results show that the Music group had significantly higher cortisol levels at T3, that is, when cortisol levels are assumed to reflect the stress induced by the game. These findings suggest for the first time that the auditory input contributes significantly to the stress response found during video game playing.

    2018-04-01

    Full Text Available Although trauma and memory have been a focus of cultural studies for more than twenty years now, few scholarly works focus on medium-specific representations of trauma and even fewer comment on the tendency of trauma representations to be autobiographical in the 21st Century. The present paper is part of a larger project that seeks to tackle precisely these issues. Here, I look at the representation of trauma in a relatively recent autobiographical video game, namely Vince Caballero’s Father and I (2012. I argue that the use of trauma as a trope adds a further narrative demand to video games, making it even more difficult to negotiate the specificities of the medium. At the same time, however, it functions as a stock story that enhances the narrative dimensions of the game under discussion.

    Although cognitive behavioral therapy (CBT) has been demonstrated to be the most effective approach for the treatment of bulimia nervosa (BN), there is lack of studies showing whether a combination with a serious video game (SVG) might be useful to enhance patients' emotional regulation capacities and general outcome. The aims of this study were (a) to analyze whether outpatient CBT + SVG, when compared with outpatient CBT - SVG, shows better short-term outcome; (b) to examine whether the CBT + SVG group is more effective in reducing emotional expression and levels of anxiety than CBT - SVG. Thirty-eight patients diagnosed as having BN according to DSM-5 criteria were consecutively assigned to two outpatient group therapy conditions (that lasted for 16 weekly sessions): 20 CBT + SVG versus 18 CBT - SVG. Patients were assessed before and after treatment using not only a food and binging/purging diary and clinical questionnaires in the field of eating disorders but also additional indexes for measuring anger expression and anxiety. Regarding the post-treatment psychometric measures, most of the mean differences (Eating Disorder Inventory-2, Symptom Checklist-Revised, State-Trait Anxiety Index, and partially State-Trait Anger Expression Inventory) achieved moderate to high effect size (d > 0.5), in the sense that CBT + SVG obtained the best results compared with the CBT - SVG group. Regarding therapy outcome (dropout, partial remission, and total remission), CBT + SVG showed better results and a moderate effect size emerged for the comparison of the risk of dropout during the treatment, being higher for CBT - SVG compared with CBT + SVG (44.1 percent versus 20.0 percent, d = 0.54). Although the sample size in our study was low, and consequently results should be considered with caution, we have obtained promising findings suggesting that in the short-term CBT + SVG might be a good option not only for improving emotional dysregulation and approaching the current limitations of CBT - SVG in BN but also for enhancing the therapy adherence of patients.

    Maillot, Pauline; Perrot, Alexandra; Hartley, Alan

    2012-09-01

    The purpose of the present study was to assess the potential of exergame training based on physically simulated sport play as a mode of physical activity that could have cognitive benefits for older adults. If exergame play has the cognitive benefits of conventional physical activity and also has the intrinsic attractiveness of video games, then it might be a very effective way to induce desirable lifestyle changes in older adults. To examine this issue, the authors developed an active video game training program using a pretest-training-posttest design comparing an experimental group (24 × 1 hr of training) with a control group without treatment. Participants completed a battery of neuropsychological tests, assessing executive control, visuospatial functions, and processing speed, to measure the cognitive impact of the program. They were also given a battery of functional fitness tests to measure the physical impact of the program. The trainees improved significantly in measures of game performance. They also improved significantly more than the control participants in measures of physical function and cognitive measures of executive control and processing speed, but not on visuospatial measures. It was encouraging to observe that, engagement in physically simulated sport games yielded benefits to cognitive and physical skills that are directly involved in functional abilities older adults need in everyday living (e.g., Hultsch, Hertzog, Small, & Dixon, 1999).

    Full Text Available BACKGROUND: Stepping impairments are associated with physical and cognitive decline in older adults and increased fall risk. Exercise interventions can reduce fall risk, but adherence is often low. A new exergame involving step training may provide an enjoyable exercise alternative for preventing falls in older people. PURPOSE: To assess the feasibility and safety of unsupervised, home-based step pad training and determine the effectiveness of this intervention on stepping performance and associated fall risk in older people. DESIGN: Single-blinded two-arm randomized controlled trial comparing step pad training with control (no-intervention. SETTING/PARTICIPANTS: Thirty-seven older adults residing in independent-living units of a retirement village in Sydney, Australia. INTERVENTION: Intervention group (IG participants were provided with a computerized step pad system connected to their TVs and played a step game as often as they liked (with a recommended dose of 2-3 sessions per week for 15-20 minutes each for eight weeks. In addition, IG participants were asked to complete a choice stepping reaction time (CSRT task once each week. MAIN OUTCOME MEASURES: CSRT, the Physiological Profile Assessment (PPA, neuropsychological and functional mobility measures were assessed at baseline and eight week follow-up. RESULTS: Thirty-two participants completed the study (86.5%. IG participants played a median 2.75 sessions/week and no adverse events were reported. Compared to the control group, the IG significantly improved their CSRT (F31,1 = 18.203, p<.001, PPA composite scores (F31,1 = 12.706, p = 0.001, as well as the postural sway (F31,1 = 4.226, p = 0.049 and contrast sensitivity (F31,1 = 4.415, p = 0.044 PPA sub-component scores. In addition, the IG improved significantly in their dual-task ability as assessed by a timed up and go test/verbal fluency task (F31,1 = 4.226, p = 0.049. CONCLUSIONS: Step pad training can be safely undertaken at home to improve physical and cognitive parameters of fall risk in older people without major cognitive and physical impairments.

    Full Text Available It’s been said that the future of a village resides in its children, and not only because they’re the future, but because it’s better if we protect and teach our children well. Thus, in 1959 the United Nations published ten principles in the Declaration of the Rights of the Child. The second principle of the Declaration of the Rights states that “the child shall enjoy special protection…to enable him to develop physically, mentally, morally, spiritually and socially…” Today, a very different social context from that of 1959, the right to protection should also be settled within the diverse areas that define new communication technologies. However, current procedures established by the PEGI, while still necessary, don’t guarantee this basic childhood right.

    A criticism of current diagnostic approaches to gaming disorder is that they fail to take into account that high and repeated engagement is not problematic per se, nor is it necessarily associated with adverse consequences. To tackle this controversy, we used Confirmatory Factor Analysis (CFA) to test, in regular gamers (N = 268), whether high (but healthy) engagement can be distinguished from problematic engagement by using the Addiction-Engagement Questionnaire (Charlton & Danforth, 2007). We then tested whether differential relationships exist between the engagement and addiction constructs, DSM-5 criteria for Internet gaming disorder (IGD), and psychological factors linked to gaming use and misuse (self-reported impulsivity, motives to play, and depression). Results indicated that a model holding engagement and addiction as two distinct, but related, constructs fits the data well. Second, we showed that although both constructs are linked to the number of IGD criteria endorsed, the relationship is more pronounced for the addiction construct. Third, a differential pattern of correlations was observed with the other study variables, further supporting the need to distinguish the two constructs. Our study emphasizes that research is needed to refine the diagnostic approach to gaming disorder to avoid conflating healthy passion with pathological behavior. Copyright © 2018 Elsevier Ltd.

    Treatments that provide feedback, increase practice with multiple repetitions, and motivate patients are essential to rehabilitation post stroke. To determine whether playing active video games results in improved balance and mobility post stroke. Thirty participants with chronic (time since stroke = 3.0 [2.9] years) hemiparesis post stroke were randomly assigned to a gaming group or normal activity control group. Gaming systems provided participants with an interactive interface of real-time movement of either themselves or an avatar on the screen. Participants played games 50-60 minutes/day, 4 days/week, for 5 weeks. The intervention was strictly game-play, in standing position, without physical therapy. The control group received no special intervention and continued with normal activity. Both groups were tested prior to, following the 5 weeks (post test), and 3 months following the completion of the study. Outcome measures included the Fugl-Meyer Assessment, Berg Balance Scale, Dynamic Gait Index, Timed Up & Go, 6-minute walk test, 3-meter walk (self-selected and fast), and perception of recovery. No statistically significant differences between or within groups were found through analysis of covariance (covaried for side of hemiparesis) at post test or follow-up. Although the within-group effect sizes were primarily indexed as "small" (effect sizes before and after testing than did the control group on all 7 dependent variables analyzed. Even though the only intervention was game-play, there were small positive effects. Therapist assistance in making more optimum movement choices may be needed before significant improvements are seen with commercially available, general purpose games.

    Stroke is one of the most serious healthcare problems and a major cause of impairment of cognition and physical functions. Virtual rehabilitation approaches to postural control have been used for enhancing functional recovery that may lead to a decrease in the risk of falling. In the present study, we investigated the effects of virtual reality balance training (VRBT) with a balance board game system on balance of chronic stroke patients. Participants were randomly assigned to 2 groups: VRBT group (11 subjects including 3 women, 65.26 years old) and control group (11 subjects including 5 women, 63.13 years old). Both groups participated in a standard rehabilitation program (physical and occupational therapy) for 60 min a day, 5 times a week for 6 weeks. In addition, the VRBT group participated in VRBT for 30 min a day, 3 times a week for 6 weeks. Static balance (postural sway velocity with eyes open or closed) was evaluated with the posturography. Dynamic balance was evaluated with the Berg Balance Scale (BBS) and Timed Up and Go test (TUG) that measures balance and mobility in dynamic balance. There was greater improvement on BBS (4.00 vs. 2.81 scores) and TUG (-1.33 vs. -0.52 sec) in the VRBT group compared with the control group (P < 0.05), but not on static balance in both groups. In conclusion, we demonstrate a significant improvement in dynamic balance in chronic stroke patients with VRBT. VRBT is feasible and suitable for chronic stroke patients with balance deficit in clinical settings.

    Multiple sclerosis (MS) is a neurodegenerative disease of the central nervous system that results in diffuse nerve damage and associated physical and cognitive impairments. Of the few comprehensive rehabilitation options that exist for populations with lower baseline cognitive functioning, those that have been successful at eliciting broad cognitive improvements have focused on a multimodal training approach, emphasizing complex cognitive processing that utilizes multiple domains simultaneously. The current study sought to determine the feasibility of an 8-week, hybrid-variable priority training (HVT) program, with a secondary aim to assess the success of this training paradigm at eliciting broad cognitive transfer effects. Capitalizing on the multimodal training modalities offered by the Space Fortress platform, we compared the HVT strategy-based intervention with a waitlist control group, to primarily assess skill acquisition and secondarily determine presence of cognitive transfer. Twenty-eight participants met inclusionary criteria for the study and were randomized to either training or waitlist control groups. To assess broad transfer effects, a battery of neuropsychological tests was administered pre- and post-intervention. The results indicated an overall improvement in skill acquisition and evidence for the feasibility of the intervention, but a lack of broad transfer to tasks of cognitive functioning. Participants in the training group, however, did show improvements on a measure of spatial short-term memory. The current investigation provided support for the feasibility of a multimodal training approach, using the HVT strategy, within the MS population, but lacked broad transfer to multiple domains of cognitive functioning. Future improvements to obtain greater cognitive transfer efficacy would include a larger sample size, a longer course of training to evoke greater game score improvement, the inclusion of only cognitively impaired individuals, and integration of subjective measures of improvement in addition to objective tests of cognitive performance.

    The addictive use of video games is recognized as a problem with clinical relevance and is included in international diagnostic manuals and classifications of diseases. The association between "Internet addiction" and mental health has been well documented across a range of investigations. However, a major drawback of these studies is that no controls have been placed on the type of Internet use investigated. The aim of this study is to review systematically the current literature in order to explore the association between Internet Gaming Disorder (IGD) and psychopathology. An electronic literature search was conducted using PubMed, PsychINFO, ScienceDirect, Web of Science and Google Scholar (r.n. CRD42018082398). The effect sizes for the observed correlations were identified or computed. Twenty-four articles met the eligibility criteria. The studies included comprised 21 cross-sectional and three prospective designs. Most of the research was conducted in Europe. The significant correlations reported comprised: 92% between IGD and anxiety, 89% with depression, 85% with symptoms of attention deficit hyperactivity disorder (ADHD), and 75% with social phobia/anxiety and obsessive-compulsive symptoms. Most of the studies reported higher rates of IGD in males. The lack of longitudinal studies and the contradictory results obtained prevent detection of the directionality of the associations and, furthermore, show the complex relationship between both phenomena.

    Between 30 and 40 % of patients with severe injuries receive treatment at non-trauma centers (under-triage), largely because of physician decision making. Existing interventions to improve triage by physicians ignore the role that intuition (heuristics) plays in these decisions. One such heuristic is to form an initial impression based on representativeness (how typical does a patient appear of one with severe injuries). We created a video game (Night Shift) to recalibrate physician's representativeness heuristic in trauma triage. We developed Night Shift in collaboration with emergency medicine physicians, trauma surgeons, behavioral scientists, and game designers. Players take on the persona of Andy Jordan, an emergency medicine physician, who accepts a new job in a small town. Through a series of cases that go awry, they gain experience with the contextual cues that distinguish patients with minor and severe injuries (based on the theory of analogical encoding) and receive emotionally-laden feedback on their performance (based on the theory of narrative engagement). The planned study will compare the effect of Night Shift with that of an educational program on physician triage decisions and on physician heuristics. Psychological theory predicts that cognitive load increases reliance on heuristics, thereby increasing the under-triage rate when heuristics are poorly calibrated. We will randomize physicians (n = 366) either to play the game or to review an educational program, and will assess performance using a validated virtual simulation. The validated simulation includes both control and cognitive load conditions. We will compare rates of under-triage after exposure to the two interventions (primary outcome) and will compare the effect of cognitive load on physicians' under-triage rates (secondary outcome). We hypothesize that: a) physicians exposed to Night Shift will have lower rates of under-triage compared to those exposed to the educational program, and b) cognitive load will not degrade triage performance among physicians exposed to Night Shift as much as it will among those exposed to the educational program. Serious games offer a new approach to the problem of poorly-calibrated heuristics in trauma triage. The results of this trial will contribute to the understanding of physician quality improvement and the efficacy of video games as behavioral interventions. clinicaltrials.gov; NCT02857348 ; August 2, 2016.

    Gambling disorder (GD) is characterized by a significant lack of self-control and is associated with impulsivity-related personality traits. It is also linked to deficits in emotional regulation and frequently co-occurs with anxiety and depression symptoms. There is also evidence that emotional dysregulation may play a mediatory role between GD and psychopathological symptomatology. Few studies have reported the outcomes of psychological interventions that specifically address these underlying processes. To assess the utility of the Playmancer platform, a serious video game, as an additional therapy tool in a CBT intervention for GD, and to estimate pre-post changes in measures of impulsivity, anger expression and psychopathological symptomatology. The sample comprised a single group of 16 male treatment-seeking individuals with severe GD diagnosis. Therapy intervention consisted of 16 group weekly CBT sessions and, concurrently, 10 additional weekly sessions of a serious video game. Pre-post treatment scores on South Oaks Gambling Screen (SOGS), Barratt Impulsiveness Scale (BIS-11), I7 Impulsiveness Questionnaire (I7), State-Trait Anger Expression Inventory 2 (STAXI-2), Symptom Checklist-Revised (SCL-90-R), State-Trait Anxiety Inventory (STAI-S-T), and Novelty Seeking from the Temperament and Character Inventory-Revised (TCI-R) were compared. After the intervention, significant changes were observed in several measures of impulsivity, anger expression and other psychopathological symptoms. Dropout and relapse rates during treatment were similar to those described in the literature for CBT. Complementing CBT interventions for GD with a specific therapy approach like a serious video game might be helpful in addressing certain underlying factors which are usually difficult to change, including impulsivity and anger expression.
