There is continuing debate on the extent of the effects of media violence on children and young people, and how to investigate these effects. The aim of this review is to consider the research evidence from a public-health perspective. A search of published work revealed five meta-analytic reviews and one quasi-systematic review, all of which were from North America. There is consistent evidence that violent imagery in television, film and video, and computer games has substantial short-term effects on arousal, thoughts, and emotions, increasing the likelihood of aggressive or fearful behaviour in younger children, especially in boys. The evidence becomes inconsistent when considering older children and teenagers, and long-term outcomes for all ages. The multifactorial nature of aggression is emphasised, together with the methodological difficulties of showing causation. Nevertheless, a small but significant association is shown in the research, with an effect size that has a substantial effect on public health. By Contrast, only weak evidence from correlation studies links media violence directly to crime. Read more...

The effects of exposure to violent video games on automatic associations with the self were investigated in a sample of 121 students. Playing the violent video game Doom led participants to associate themselves with aggressive traits and actions on the Implicit Association Test. In addition, self-reported prior exposure to violent video games predicted automatic aggressive self-concept, above and beyond self-reported aggression. Results suggest that playing violent video games can lead to the automatic learning of aggressive self-views. Read more...

Background and Purpose: Performance of laparoscopic surgery requires adequate hand-eye coordination. Video games are an effective way to judge one's hand-eye coordination, and practicing these games may improve one's skills. Our goal was to see if there is a correlation between skill in video games and skill in laparoscopy. Also, we hoped to demonstrate that practicing video games can improve one's laparoscopic skills. Subjects and Methods: Eleven medical students (nine male, two female) volunteered to participate. On day 1, each student played three commercially available video games (Top Spin, XSN Sports; Project Gotham Racing 2, Bizarre Creations; and Amped 2, XSN Sports) for 30 minutes on an X-box (Microsoft, Seattle, WA) and was judged both objectively and subjectively. Next, the students performed four laparoscopic tasks (object transfer, tracing a figure-of-eight, suture placement, and knot-tying) in a swine model and were assessed for time to complete the task, number of errors committed, and hand-eye coordination. The students were then randomized to control (group A) or "training" (i.e., video game practicing; group B) arms. Two weeks later, all students repeated the laparoscopic skills laboratory and were reassessed. Results: Spearman correlation coefficients demonstrated a significant relation between many of the parameters, particularly time to complete each task and hand-eye coordination at the different games. There was a weaker association between video game performance and both laparoscopic errors committed and hand-eye coordination. Group B subjects did not improve significantly over those in group A in any measure (P >0.05 for all). Conclusion: Video game aptitude appears to predict the level of laparoscopic skill in the novice surgeon. In this study, practicing video games did not improve one's laparoscopic skill significantly, but a larger study with more practice time could prove games to be helpful. Read more...

Objectives. To explore the association between early computer experience (both accessibility and frequency of use) and cognitive and psychomotor development among young children. Methods. The participants were 122 preschool children enrolled in a rural county Head Start program in the United States during 2001-2002. The following tests were administered to the children: the Bender Visual Motor Gestalt Test; the Boehm Test of Basic Concepts, Third Edition Preschool; the Test of Gross Motor Development, Second Edition; and a short form of the Wechsler Preschool and Primary Scales of Intelligence-Revised. Information pertaining to family characteristics and children's early computer experience was collected from parents. Both bivariate and multivariate analyses were used to assess the association between early computer experience and cognitive and motor development. Results. Of the participating children, 53% had a computer at home. Among families who had a computer, 83% had children's software on the computer. According to parents' reports, 29% of these children played on the home computer on a daily basis, and an additional 44% of the children played on the computer at least weekly. Of those families who did not have a home computer, 49% reported that their children had access to a computer somewhere outside home. Among these children, 10% had daily access to the computer and 33% had weekly access. The presence of a computer in the home was significantly associated with the family's income and the educational attainment of the parents. There was no gender difference in computer accessibility and frequency use among the participating children. Children who had access to a computer performed better on measures of school readiness and cognitive development, controlling for children's developmental stage and family socioeconomic status. The data in the current study did not suggest a relationship between computer experience and visual motor or gross motor skills among the participating children. Conclusion. The findings in the present study suggest that early computer exposure before or during the preschool years is associated with development of preschool concepts and cognition among young children. However, frequency of use did not reveal such a relationship; neither did the ownership of other child electronic or video games in the household. Read more...

It has been speculated that computer game play by young people has negative correlates or consequences, although little evidence has emerged to support these fears. An alternative possibility is that game play may be associated with positive features of development, as the games reflect and contribute to participation in a challenging and stimulating voluntary leisure environment. This study examined the relationship between game play and several measures of adjustment or risk taking in a sample of 16-year-old high school students. No evidence was obtained of negative outcomes among game players. On several measures-including family closeness, activity involvement, positive school engagement, positive mental health, substance use, self-concept, friendship network, and disobedience to parents-game players scored more favorably than did peers who never played computer games. It is concluded that computer games can be a positive feature of a healthy adolescence. Read more...
