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.

Childhood sexual abuse and revictimization in adolescence

OBJECTIVE The aim of this study was to examine the link between childhood experiences of sexual abuse and subsequent revictimization in adolescence. METHOD A sample of 281 female adolescents between 17-20 years of age, who participated in a prevalence survey of unwanted sexual contacts, completed the Sexual Experiences Survey as a measure of unwanted sexual contacts in adolescence and indicated whether or not they had experienced childhood sexual abuse. RESULTS Childhood experiences of sexual abuse were reported by 8.9% of the respondents, a further 8.5% indicated they were not sure if they had been sexually abused as children. Both abused women and women uncertain about their victimization status were significantly more likely to report unwanted sexual contacts as adolescents than women who did not state abuse. The link between childhood abuse and subsequent victimization was mediated by a higher level of sexual activity among the abuse victims. CONCLUSIONS The results support existing evidence on the impact of childhood sexual abuse on sexual relationships in subsequent developmental stages and underline the need to consider childhood sexual abuse as a risk factor of adolescent sexual victimization.

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.

Blaming the Victim and Exonerating the Perpetrator in Cases of Rape and Robbery: Is There a Double Standard?

Research in legal decision making has demonstrated the tendency to blame the victim and exonerate the perpetrator of sexual assault. This study examined the hypothesis of a special leniency bias in rape cases by comparing them to cases of robbery. N = 288 participants received descriptions of rape and robbery of a female victim by a male perpetrator and made ratings of victim and perpetrator blame. Case scenarios varied with respect to the prior relationship (strangers, acquaintances, ex-partners) and coercive strategy (force vs. exploiting victim intoxication). More blame was attributed to the victim and less blame was attributed to the perpetrator for rape than for robbery. Information about a prior relationship between victim and perpetrator increased ratings of victim blame and decreased perceptions of perpetrator blame in the rape cases, but not in the robbery cases. The findings support the notion of a special leniency bias in sexual assault cases.

Long-Term Relations Among Prosocial-Media Use, Empathy, and Prosocial Behavior

Despite recent growth of research on the effects of prosocial media, processes underlying these effects are not well understood. Two studies explored theoretically relevant mediators and moderators of the effects of prosocial media on helping. Study 1 examined associations among prosocial- and violent-media use, empathy, and helping in samples from seven countries. Prosocial-media use was positively associated with helping. This effect was mediated by empathy and was similar across cultures. Study 2 explored longitudinal relations among prosocial-video-game use, violent-video-game use, empathy, and helping in a large sample of Singaporean children and adolescents measured three times across 2 years. Path analyses showed significant longitudinal effects of prosocial- and violent-video-game use on prosocial behavior through empathy. Latent-growth-curve modeling for the 2-year period revealed that change in video-game use significantly affected change in helping, and that this relationship was mediated by change in empathy.

Social Psychological Issues in the Study of Rape

The chapter presents a social psychological approach to the study of rape and sexual assault. Two issues are at the core of this approach: identifying the critical variables that affect attributions of responsibility to victims of rape, and exploring peoples subjective definitions of rape, which may differ markedly from legal definitions. Following a review of the American evidence, a series of studies conducted in two European countries is presented to address these issues.

Ambiguous Communication of Sexual Intentions as a Risk Marker of Sexual Aggression

Three studies are reported that explored the role of ambiguous communication of sexual intentions as a risk factor for sexual aggression and victimization. Two main forms of ambiguous communication were distinguished: token resistance (saying “no” when you mean “yes”) and compliance (saying “yes” when you mean “no”). Two samples of heterosexual men and women and a sample of homosexual men with a total N of 1284 completed a measure of sexual victimization or aggression and indicated whether or not they had ever shown token resistance or compliance in a sexual encounter. Moreover, the heterosexual male respondents indicated whether they had ever perceived token resistance or compliance in a female partner. Logistic regression analyses revealed that the risk of experiencing sexual victimization was significantly increased as a function of token resistance. Two of the three studies also showed compliance to be a risk factor for sexual victimization. For the male respondents, token resistance was consistently linked to a higher likelihood of perpetrating sexually aggressive acts in the three studies. Perceived compliance was also found to increase the risk of sexual aggression in three of four analyses. Support for a link between perceived token resistance and sexual aggression was found in the first study only. Overall, the findings suggest that the use of ambiguous communication in negotiating sexual encounters is associated with an increased risk of sexual victimization as well as perpetration of sexually aggressive acts in both heterosexual and homosexual contacts. The implications of the findings are discussed with respect to the issue of rape prevention.

Prospective lawyers’ rape stereotypes and schematic decision making about rape cases

Abstract Two studies explored stereotypic information processing in rape cases by prospective lawyers in Germany. In Study 1, 451 undergraduate law students rated rape scenarios varying with respect to defendant–complainant relationship and coercive strategy (force versus exploitation of the complainants alcohol-induced defencelessness). Acceptance of rape myths was also measured. Likelihood of defendant liability was rated to be lower when there was a prior relationship between the parties and when the defendant exploited the complainants defencelessness as compared to when he used force (except in the ex-partner rapes where blame was higher in the alcohol-related than in the force-related cases). Complainant blame was higher when there was a prior relationship between the parties and was higher in the alcohol-related cases than in the force-related cases, except in the ex-partner rape where the pattern was reversed. Participants with high rape myth acceptance held the defendant less liable and blamed the complainant more, especially when the two had known each other. Study 2 largely replicated these findings with 129 postgraduate trainee lawyers and showed that sentencing recommendations also varied as a function of defendant–complainant relationship and coercive strategy. Providing participants with the legal definition of rape did not reduce reliance on rape stereotypes.

Men's reports of nonconsensual sexual interactions with women: prevalence and impact.

Two studies examined the prevalence and emotional impact of mens nonconsensual sexual interactions with women. The first study included a sample of 247 heterosexual men with a mean age of 18.3 years. The second study was a replication with a sample of 153 heterosexual men with a mean age of 22.3 years. All respondents completed a measure of nonconsensual sexual interactions including the use of three aggressive strategies (physical force, exploitation of the mans incapacitated state, and verbal pressure) and three forms of unwanted sexual contact (kissing/petting, sexual intercourse, and oral sex). In addition, the relationship to the female initiator was explored. For each type of nonconsensual sexual interaction, respondents indicated the affective impact of the experience. In Study 1, 25.1% of respondents reported at least one incident of nonconsensual sex with a woman and 23.9% reported attempts by women to make them engage in nonconsensual sexual activity. In Study 2, the overall prevalence rate for completed nonconsensual sexual interactions was 30.1%, and 23.5% of the men reported attempts at making them engage in nonconsensual sex. In both samples, exploiting the mans inability to offer resistance was the most frequently reported aggressive strategy. Kissing/petting was the most frequently reported unwanted sexual activity, followed by sexual intercourse and oral sex. Prevalence rates were higher for nonconsensual sex with an (ex-)partner or friend than for nonconsensual sex with an unknown women. Ratings of affective impact revealed that men rated their nonconsensual experiences as moderately upsetting. The findings are discussed in the light of previous studies on mens unwanted sexual experiences and the extant literature on womens nonconsensual sexual interactions with men.
