Exposure to violent video games and aggression in German adolescents: a longitudinal analysis

The relationship between exposure to violent electronic games and aggressive cognitions and behavior was examined in a longitudinal study. A total of 295 German adolescents completed the measures of violent video game usage, endorsement of aggressive norms, hostile attribution bias, and physical as well as indirect/relational aggression cross-sectionally, and a subsample of N=143 was measured again 30 months later. Cross-sectional results at T1 showed a direct relationship between violent game usage and aggressive norms, and an indirect link to hostile attribution bias through aggressive norms. In combination, exposure to game violence, normative beliefs, and hostile attribution bias predicted physical and indirect/relational aggression. Longitudinal analyses using path analysis showed that violence exposure at T1 predicted physical (but not indirect/relational) aggression 30 months later, whereas aggression at T1 was unrelated to later video game use. Exposure to violent games at T1 influenced physical (but not indirect/relational) aggression at T2 via an increase of aggressive norms and hostile attribution bias. The findings are discussed in relation to social-cognitive explanations of long-term effects of media violence on aggression.

Desensitization to Media Violence: Links With Habitual Media Violence Exposure, Aggressive Cognitions, and Aggressive Behavior

This study examined the links between desensitization to violent media stimuli and habitual media violence exposure as a predictor and aggressive cognitions and behavior as outcome variables. Two weeks after completing measures of habitual media violence exposure, trait aggression, trait arousability, and normative beliefs about aggression, undergraduates (N = 303) saw a violent film clip and a sad or a funny comparison clip. Skin conductance level (SCL) was measured continuously, and ratings of anxious and pleasant arousal were obtained after each clip. Following the clips, participants completed a lexical decision task to measure accessibility of aggressive cognitions and a competitive reaction time task to measure aggressive behavior. Habitual media violence exposure correlated negatively with SCL during violent clips and positively with pleasant arousal, response times for aggressive words, and trait aggression, but it was unrelated to anxious arousal and aggressive responding during the reaction time task. In path analyses controlling for trait aggression, normative beliefs, and trait arousability, habitual media violence exposure predicted faster accessibility of aggressive cognitions, partly mediated by higher pleasant arousal. Unprovoked aggression during the reaction time task was predicted by lower anxious arousal. Neither habitual media violence usage nor anxious or pleasant arousal predicted provoked aggression during the laboratory task, and SCL was unrelated to aggressive cognitions and behavior. No relations were found between habitual media violence viewing and arousal in response to the sad and funny film clips, and arousal in response to the sad and funny clips did not predict aggressive cognitions or aggressive behavior on the laboratory task. This suggests that the observed desensitization effects are specific to violent content.

Women's Sexual Aggression Against Men: Prevalence and Predictors

In this study, we investigated the prevalence of womens sexual aggression against men and examined predictors of sexual aggression in a sample of 248 women. Respondents reported their use of aggressive strategies (physical force, exploitation of a mans incapacitated state, and verbal pressure) to make a man engage in sexual touch, sexual intercourse, or oral sex against his will. Childhood abuse, gender role orientation, ambiguous communication of sexual intentions, level of sexual activity, and peer pressure were included as predictors of sexual aggression. Almost 1 in 10 respondents (9.3%) reported having used aggressive strategies to coerce a man into sexual activities. Exploitation of the mans incapacitated state was used most frequently (5.6%), followed by verbal pressure (3.2%) and physical force (2%). An additional 5.4% reported attempted acts of sexual aggression. Sexual abuse in childhood, ambiguous communication of sexual intentions, high levels of sexual activity, and peer pressure toward sexual activity were linked to an increased likelihood of sexual aggression. The findings are discussed in relation to the literature on mens sexual aggression.

Report of the Media Violence Commission

Editor’s Note: In December, 2011, the International Society for Research on Aggression appointed a special commission to prepare a report on media violence. Their charge was as follows: “The ISRA Violent Media Effects Commission is charged with the task of producing a public statement on the known effects of exposure to media violence, based on the current state of scientific knowledge. If the Commission finds sufficient evidence of harmful effects, then the Commission’s public statement may include public policy recommendations, keeping in mind that effective policies may well differ across countries because of their different legal and cultural traditions and systems. The statement could be an original statement by the Commission, or could be an endorsement or modification of one or more similar statements offered in recent years by other major scientific bodies and/or groups of scientists who have appropriate expertise in the media violence domain. The statement (if sufficiently brief) or an Executive Summary statement (of a longer, more detailed statement) will be published in ISRA’s journal Aggressive Behavior and will appear on the ISRA web site. It may also be published in the ISRA Bulletin.” What follows is the final report of the Media Violence Commission, delivered in May, 2012. This statement was written by a group of internationally recognized active researchers in the field of media violence to summarize current knowledge about the strength of the link between violent media use and aggression, explain the psychological processes by which violent media may increase the risk of aggressive behavior, and offer practical advice on how parents and policy makers can deal with the issue.

Factors underlying male and female use of violent video games

Research has consistently shown that males play violent video games more frequently than females, but factors underlying this gender gap have not been examined to date. This approach examines the assumption that males play violent video games more because they anticipate more enjoyment and less guilt from engaging in virtual violence than females. This may be because males are less empathetic, tend to morally justify physical violence more and have a greater need for sensation and aggression in video game play than females. Results of a path model based on survey data of 444 respondents and using multi-step multiple mediation analyses confirm these assumptions. Taken together, the findings of this study shed further light on the gender gap in violent video game use.

Repression Versus Sensitization in Response to Media Violence as Predictors of Cognitive Avoidance and Vigilance

Repression and sensitization as situational modes of coping with anxiety were examined as predictors of trait measures of cognitive avoidance and vigilance. In this study, 303 undergraduates saw a violent film clip to elicit anxiety. Increases in skin conductance level (SCL) and state anxiety (STA) from baseline were measured to identify repressors (high SCL, low STA) and contrast them with sensitizers (low SCL, high STA) and genuinely low anxious individuals (low SCL, low STA). State anger was also recorded. Trait measures of vigilance and cognitive avoidance were collected 2 weeks earlier. Significant SCL × STA interactions indicated that repressors scored higher on cognitive avoidance and lower on vigilance compared to sensitizers and low anxious participants. Repressors were less likely than sensitizers to report gaze avoidance during the clip. The anger by SCL interaction was nonsignificant, suggesting that repressors and sensitizers differ specifically in the processing of anxiety rather than negative affect in general.

Gewalt in Bildschirmspielen und aggressives Verhalten

Gewalthaltige Bildschirmspiele erfreuen sich unter Jugendlichen groser Beliebtheit. Diese Art der Spiele erlauben es den Nutzer/innen, neben der Auslebung sozialer Motive vor allem im Jugendalter stark ausgepragte Bedurfnisse zu befriedigen: Action-Adventures und Shooter bieten z.B. Gelegenheiten, Spannung und Nervenkitzel sowie aufregende negative Gefuhle wie Angst und Ekel gefahrfrei zu erleben.
