Media Violence
New entry in Digiplay games research bibliography:
Possible associations between television viewing and video game playing and children's aggression have become public health concerns. We did a systematic review of studies that examined such associations, focussing on children and young people with behavioural and emotional difficulties, who are thought to be more susceptible.We did computer-assisted searches of health and social science databases, gateways, publications from relevant organizations and for grey literature; scanned bibliographies; hand-searched key journals; and corresponded with authors. We critically appraised all studies.A total of 12 studies: three experiments with children with behavioural and emotional difficulties found increased aggression after watching aggressive as opposed to low-aggressive content television programmes, one found the opposite and two no clear effect, one found such children no more likely than controls to imitate aggressive television characters. One case-control study and one survey found that children and young people with behavioural and emotional difficulties watched more television than controls; another did not. Two studies found that children and young people with behavioural and emotional difficulties viewed more hours of aggressive television programmes than controls. One study on video game use found that young people with behavioural and emotional difficulties viewed more minutes of violence and played longer than controls. In a qualitative study children with behavioural and emotional difficulties, but not their parents, did not associate watching television with aggression. All studies had significant methodological flaws. None was based on power calculations.This systematic review found insufficient, contradictory and methodologically flawed evidence on the association between television viewing and video game playing and aggression in children and young people with behavioural and emotional difficulties. If public health advice is to be evidence-based, good quality research is needed.

We examined the causal relationship between playing violent video games and increases in aggressiveness by using implicit measures of aggressiveness, which have become important for accurately predicting impulsive behavioral tendencies. Ninety-six adults were randomly assigned to play one of three versions of a computer game that differed only with regard to game content (violent, peaceful, or abstract game), or to work on a reading task. In the games the environmental context, mouse gestures, and physiological arousal-as indicated by heart rate and skin conductance-were kept constant. In the violent game soldiers had to be shot, in the peaceful game sunflowers had to be watered, and the abstract game simply required clicking colored triangles. Five minutes of play did not alter trait aggressiveness, yet an Implicit Association Test detected a change in implicit aggressive self-concept. Playing a violent game produced a significant increase in implicit aggressive self-concept relative to playing a peaceful game. The well-controlled study closes a gap in the research on the causality of the link between violence exposure in computer games and aggressiveness with specific regard to implicit measures. We discuss the significance of importing recent social-cognitive theory into aggression research and stress the need for further development of aggression-related implicit measures.

Public policy efforts to restrict children's access to electronic games with violent or sexual content are often predicated on assumptions about parental concerns. As an initial step in determining whether those assumptions are accurate, the authors conduct focus groups of 21 adolescent boys and 21 of their parents or guardians to explore parents' concerns, compare parents' and children's perceptions, and see whether these are consistent with the focus of proposed legislation and other public policy efforts. Parents' primary concern is that games not interfere with their children's schoolwork, social skills, and exercise. They worry about exposure to violent content, but definitions of and opinions about what is harmful vary and may not match proposed public policies. \copyright2008 Sage Publications.

Numerous policies have been proposed at the local, state, and national level to restrict youth access to violent video and computer games. Although studies are cited to support policies, there is no published research on how children perceive the uses and influence of violent interactive games. The authors conduct focus groups with 42 boys ages 12 to 14. Boys use games to experience fantasies of power and fame, to explore and master what they perceive as exciting and realistic environments (but distinct from real life), to work through angry feelings or relieve stress, and as social tools. Boys did not believe they had been harmed by violent games but were concerned that younger children might imitate game behavior (especially swearing). \copyright2008 Sage Publications.

Decades of research have demonstrated that exposure to violence on television can cause increases in aggression. The recent emergence of violent video games has raised new questions regarding the effects of violent media. The General Aggression Model (GAM) predicts that exposure to violent media increases aggressive behavior through one of three primary pathways (arousal, cognitions, and affect). Past psychophysiological research has supported GAM but has been limited to examining arousal-related variables. Recent advances in social neuroscience have opened the door to investigations of exposure to violent media on cognitive and affective components and their neurocognitive underpinnings. Neuroscience tools have the potential to provide answers to the new questions posed by recent advances in media technology.

Purpose: To compare the video and computer game play patterns of young adolescent boys and girls, including factors correlated with playing violent games. Methods: Data collected in November/December, 2004 from children in grades 7 and 8 at two demographically diverse schools in Pennsylvania and South Carolina, using a detailed written self-reported survey. Results: Of 1254 participants (53% female, 47% male), only 80 reported playing no electronic games in the previous 6 months. Of 1126 children who listed frequently played game titles, almost half (48.8%) played at least one violent (mature-rated) game regularly (67.9% of boys and 29.2% of girls). One third of boys and 10.7% of girls play games nearly every day; only 1 in 20 plays often or always with a parent. Playing M-rated games is positively correlated (p < .001) with being male, frequent game play, playing with strangers over the Internet, having a game system and computer in one's bedroom, and using games to manage anger. Conclusions: Most young adolescent boys and many girls routinely play M-rated games. Implications for identifying atypical and potentially harmful patterns of electronic game use are discussed, as well as the need for greater media literacy among parents.

Repeated exposure to violent media is related to negative outcomes, including aggression, hostility, and cognitive and social deficits. We examined if cardiovascular and emotional responding to video game play changed across 3 weekly sessions. Participants were 41 adolescents (M age = 14.8; male = 29; female = 12) from rural Appalachia. Participants attended 3 weekly sessions and played I of 3 video games (basketball, fighting, or horror) each time. Measures included heart rate (HR); systolic blood pressure (SBP); diastolic blood pressure (DBP); self-reported aggression, anger, and reactions to game play; and history of video game play. Resting and posttest cardiovascular measures did not differ from session to session. Adolescents displayed HR and SBP reactivity to game play within each session. They also demonstrated decreased SBP and DBP responding to video game play across the 3-week period, regardless of game content. Affective responses did not change significantly across the course of the experiment. Adolescents who played the violent games reported more frustration and arousal than those who played the sports game. The implications of these findings are discussed.

This study aims to advance the media effects debate concerning violent video games. Meta-analytic reviews reveal a small but noticeable association between playing violent video games and aggressive reactions. However, evidence for causal associations is still rare. In a novel, event-related functional magnetic resonance imaging study, 13 male research participants were observed playing a latest-generation violent video game. Each participant's game play was recorded and content analyzed on a frame-by-frame basis. Onscreen activities were coded as either "passive/dead, no a frame interactions"; "active/safe, no imminent danger/no violent interactions"; "active/potential danger occurs, violent interactions expected"; "active/under attack, some violent interactions"; and "active/fighting and killing, many violent interactions." Previous studies in neuroscience on aggressive thoughts and behaviors suggested that virtual violence would suppress affective areas of the anterior cingulate cortex (ACC) and the amygdala subsequent to activity variations at cognitive areas of the ACC. Comparison of game play activities with and without virtual violence in 11 participants confirmed the hypothesis. The rather large observed effects can be considered as caused by the virtual violence. We discuss the applicability of neuroscience methodology in media effects studies, with a special emphasis on the assumption of virtuality prevalent in video game play.

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.

Playing violent video games is related to increased negative affect and cardiovascular reactivity. We examined the influence of high and low aggressive priming during video-game training on violence during game play (e.g., shooting, choking), hostility, frustration with game play, blood pressure, and heart rate. Male undergraduates (N = 36) were assigned to a high aggressive or low aggressive video-game priming condition. After training, they played Metal Gear Solid(TM), which allows players to advance by using stealth, violence, or both. Participants in the high aggressive priming condition used significantly more violent action during game play and reported more hostility than those in the low aggressive priming condition. Heart rate was correlated with feelings of hostility. These findings indicate that both aggressive priming and use of game violence influence arousal and negative affect and might increase behavioral aggression.
