Childhood obesity, which is due in part to lack of physical activity, is a serious concern that requires the attention of the behavioral community. Although excessive video game play has been noted in the literature as a contributor to childhood obesity, newer video gaming technology, called exergaming, has been designed to capitalize on the reinforcing effects of video games to increase physical activity in children. This study evaluated the effects of exergaming on physical activity among 4 inactive children in a physical education (PE) classroom. Results showed that exergaming produced substantially more minutes of physical activity and more minutes of opportunity to engage in physical activity than did the standard PE program. In addition, exergaming was socially acceptable to both the students and the PE teacher. Exergaming appears to hold promise as a method for increasing physical activity among inactive children and might be a possible intervention for childhood obesity.  相似文献

Although research in social psychology has repeatedly refuted the idea that aggression reduces subsequent aggression (e.g., Bushman, 2002), we suggest a more fine-grained analysis of catharsis. We will present and discuss a social-cognitive goal model of cathartic effects in aggression that predicts under which conditions aggression increases or reduces subsequent aggression. The model assumes that the accessibility of aggression-related constructs is a function of goal fulfilment: Prior to goal fulfilment constructs related to the goal are highly accessible in order to facilitate goal fulfilment. However, after goal fulfilment this heightened accessibility loses its functionality and aggressive constructs are consequently inhibited. In the present article we will review empirical work testing this model. Moreover, we will extend this model to the effects of violent computer games. Finally we will discuss theoretical challenges and applied relevance of our model for intervention strategies aimed at reducing aggression.  相似文献

This study aimed to explore Chinese children's social value orientation across different ages and contexts. Revised decomposed games were used to measure the social value orientation of 9‐, 11‐, and 14‐year‐old children and college students as an adult group. About half of them were assigned to the hypothetical context of “equal payment group,” providing equal compensation for participation in the study, and the others to the “real payment group,” who got payment according to their own choices in the games. Results showed that 9‐ and 11‐year‐old children's choices differed between the two contexts: They made more prosocial choices in the hypothetical context, and more competitive choices in the “real payment” context. The 14‐year‐olds’ and adults’ choices were not significantly different in the two contexts. These results may imply that by 14 years of age, children have stable social value orientation, and their behavior reflects this value.  相似文献

The authors investigated the relation between mental rotation (MR) and computer game-playing experience. Third grade boys (n = 24) and girls (n = 23) completed a 2-dimensional MR test before and after playing computer games (during 11 separate 30-min sessions), which either involved the use of MR skills (the experimental group) or did not involve the use of MR skills (the control group). The experimental group outperformed the control group on the MR posttest but not on the pretest. Boys outperformed girls on the pretest but not on the posttest. Children whose initial MR performance was low improved after playing computer games that entailed MR skills. The findings imply that computer-based instructional activities can be used in schools to enhance children's spatial abilities.  相似文献

This paper explores some issues that might arise when one considers having a table hockey game in the therapy room, and describes how an autistic boy, aged four-and-a-half when starting treatment, used that game. The unfolding process from withdrawal to separateness, intersubjectivity and playfulness is illustrated by the progress of two years of twice-weekly psychoanalytic psychotherapy. Special attention is paid to how the play progressed through the intermediate area that the therapist provided.  相似文献

The catalyst model suggests that adult criminality arises from the interaction of genetic and proximal social influences such as family influences, but that distal social influences such as media exposure have only negligible influence. This article uses data from a 13-year longitudinal study of adolescent health to examine the catalyst model. As expected by the catalyst model, adult criminality was best explained by a confluence of genetic and proximal social risk factors. The influence of media exposure on adult criminality was negligible. Implications of these findings for both theory and policy are discussed.  相似文献

ABSTRACT

We investigated the feasibility of using the Space Fortress (SF) game, a complex video game originally developed to study complex skill acquisition in young adults, to improve executive control processes in cognitively healthy older adults. The study protocol consisted of 36 one-hour game play sessions over 3 months with cognitive evaluations before and after, and a follow-up evaluation at 6 months. Sixty participants were randomized to one of three conditions: Emphasis Change (EC) – elders were instructed to concentrate on playing the entire game but place particular emphasis on a specific aspect of game play in each particular game; Active Control (AC) – game play with standard instructions; Passive Control (PC) – evaluation sessions without game play. Primary outcome measures were obtained from five tasks, presumably tapping executive control processes. A total of 54 older adults completed the study protocol. One measure of executive control, WAIS-III letter–number sequencing, showed improvement in performance from pre- to post-evaluations in the EC condition, but not in the other two conditions. These initial findings are modest but encouraging. Future SF interventions need to carefully consider increasing the duration and or the intensity of the intervention by providing at-home game training, reducing the motor demands of the game, and selecting appropriate outcome measures.  相似文献

We first state a few previously obtained results that lead to general undecidability and incompleteness theorems in axiomatized theories that range from the theory of finite sets to classical elementary analysis. Out of those results we prove several incompleteness theorems for axiomatic versions of the theory of noncooperative games with Nash equilibria; in particular, we show the existence of finite games whose equilibria cannot be proven to be computable.  相似文献

IntroductionInternet Gaming Disorder (IGD) was introduced for the first time within the “conditions for further study” in the fifth edition of the Diagnostic and Statistical Manual of the American Psychiatric Association, and a systematic review has concluded that the only available instrument for its measurement is the Problem Video Game Playing scale (PVP). Nevertheless, this scale was presented as a diagnostic tool for adolescents, and to date no study has analyzed its properties amongst adults.ObjectiveThe aim of the study was to analyze and compare the diagnostic and psychometric properties of the PVP in adult and adolescent gamers.MethodTwo samples of adult (n = 525) and adolescent (n = 384) gamers completed a survey including patterns of play, PVP, Severity of Dependence Scale, and other measures of playing to excess.ResultsConfirmatory factor analyses revealed that the scale presents a one-factor structure that is similar to that of the original version, both in adults and adolescents. Construct validity was supported by highly significant associations between the PVP and all alternative measures of playing to excess. On the other hand, reliability values were lower than in previous studies.ConclusionsThe PVP scale's properties are appropriate for the measurement of problem video gaming in adults as well as in adolescents, but studies with clinical assessments are still needed before any cutoff value for diagnosis can be established.  相似文献
