Genetic,Maternal, School,Intelligence, and Media Use Predictors of Adult Criminality: A Longitudinal Test of the Catalyst Model in Adolescence through Early Adulthood

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.     

Space Fortress game training and executive control in older adults: A pilot intervention

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.     

The Incompleteness of Theories of Games

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.     

Psychometric properties of the Problem Video Game Playing scale in adults

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.     

亲社会视频游戏对国外青少年行为的影响

视频游戏对青少年行为影响的研究焦点主要集中在暴力视频游戏带来的消极影响上。随着研究的深入以及积极心理学的兴起,研究者开始关注亲社会视频游戏对青少年行为的积极影响,并进行了相关的研究,研究大多以一般学习模型为理论框架。一般学习模型认为亲社会视频游戏通过影响与亲社会相关的认知、情感和生理唤醒而对亲社会行为产生作用。已有研究显示,亲社会视频游戏会促进青少年的亲社会行为,同时减少青少年的攻击性行为。研究者们采用多种方法探索亲社会视频游戏影响青少年行为的心理机制,证明了一般学习模型的理论构想。未来研究需要进一步研究性别、人格、文化等因素的影响,并开展相关的认知神经机制研究。     

Attachment and behavioral addictions in adolescents: The mediating and moderating role of coping strategies

Gambling, video gaming, and Internet use are typically included as everyday activities that could potentially become behavioral addictions. There is growing evidence that views non‐substance related addictions as coping mechanisms, and considers that attachment styles are likely to play a pivotal role on the development of such addictions, especially on young people. Therefore, the present study aimed to: (1) explore the association between attachment, coping, and behavioral addictions (i.e., gambling disorder, video game addiction, and problematic Internet use); and (2) to analyze the mediating/moderating effect that coping has in the relationship of attachment and these behavioral addictions. A sample consisting of 472 students from secondary education (Mean age = 15.6; SD = 1.33; 51.6% females) was recruited. The findings showed a negative association between attachment and behavioral addictions. Most coping strategies were found to be associated with attachment styles, except for self‐critique and emotional avoidance. In particular, problem avoidance was significantly correlated to all behavioral addictions. In addition, self‐blame and problem solving were significantly correlated to video game addiction and problematic Internet use. Finally, coping was found to act as a mediator and moderator between attachment and video game addiction and problematic Internet use.     

The contagious impact of playing violent video games on aggression: Longitudinal evidence

Meta-analyses have shown that violent video game play increases aggression in the player. The present research suggests that violent video game play also affects individuals with whom the player is connected. A longitudinal study (N = 980) asked participants to report on their amount of violent video game play and level of aggression as well as how they perceive their friends and examined the association between the participant's aggression and their friends’ amount of violent video game play. As hypothesized, friends’ amount of violent video game play at Time 1 was associated with the participant's aggression at Time 2 even when controlling for the impact of the participant's aggression at Time 1. Mediation analyses showed that friends’ aggression at Time 1 accounted for the impact of friends’ amount of violent video game play at Time 1 on the participant's aggression at Time 2. These findings suggest that increased aggression in video game players has an impact on the player's social network.     

Effects of a handwashing intervention package on handwashing in preschool children

Young children who attend out‐of‐home care (e.g., preschool) are more susceptible to infections than children who do not attend out‐of‐home care. Previous research suggests handwashing is effective in reducing risk of infection and illness. However, research suggests that individuals do not routinely wash their hands using methods that healthcare agencies, such as the Centers for Disease Control and Prevention, have determined best practice. We evaluated the effects of a multicomponent handwashing intervention package on correct handwashing across groups of preschool children. Furthermore, we measured the degree to which their hands were clean using premeasures and postmeasures. Results suggest the intervention package was effective at increasing both correct handwashing and cleanliness of participants' hands.
