With a Little Help from Their Peers: The Impact of Classmates on Adolescents’ Development of Prosocial Behavior
Peer groups are critical socialization agents for the development of social behavior in adolescence, but studies examining peer-group effects on individuals’ prosocial behavior are scarce. Using a two-wave, multilevel data set (N = 16,893, 8481 male; 8412 female; mean age at Time 1: 14.0 years) from 1308 classes in 252 secondary schools in Germany, main effects of the classroom level of prosocial behavior, cross-level interactions between the classroom and the individual levels of prosocial behavior at Time 1, and the moderating role of gender were examined. The results showed that adolescents in classrooms with high collective levels of prosocial behavior at Time 1 reported more prosocial behavior at Time 2, about two years later, reflecting a class-level main effect. A significant cross-level interaction indicated that a high classroom level of prosocial behavior particularly affected individuals with lower levels of prosocial behavior at Time 1. The influence of same-gender peers was larger compared with opposite-gender peers. The findings are discussed with respect to social learning mechanisms in the development of prosocial behavior and their implications for interventions to promote prosocial behavior.

Gendered Self-Concept and the Aggressive Expression of Driving Anger: Positive Femininity Buffers Negative Masculinity
The aggressive expression of driving anger is a risk factor for aggressive and dangerous driving behavior and is associated with a greater risk of accident involvement. The present study related positive and negative facets of a masculine and feminine self-concept to aggressive and adaptive forms of anger expression while driving. A sample of 417 drivers (194 women, 46.5%) in Germany completed the Positive-Negative Sex Role Inventory (PN-SRI) as a measure of positive and negative masculinity and femininity and the Driving Anger Expression Inventory (DAX) as a measure of driving anger expression. Aggressive forms of expressing driving anger were unrelated to gender but differed significantly in relation to gendered self-concept. Negative but not positive masculinity was found to predict higher aggressive and lower adaptive anger expression. No main effects of positive or negative femininity were found. However, the link between negative masculinity and aggressive anger expression was buffered by positive femininity: Negative masculinity was unrelated to aggressive anger expression when accompanied by positive femininity. Adaptive anger expression showed negative links with negative masculinity and positive links with positive masculinity. The findings held for both men and women and support the theoretical distinction between positive and negative facets of the gendered self-concept. The implications for the conceptualization of both gendered self-concept and anger expression on the road are discussed.

Predictors of Sexual Aggression Victimization and Perpetration Among Polish University Students: A Longitudinal Study
This two-wave study investigated predictors of sexual aggression victimization and perpetration in a convenience sample of 318 Polish university students (214 women), considering males and females from the perspective of both victims and perpetrators. At T1, we assessed participants’ risky sexual scripts (defined as cognitive representations of consensual sexual interactions containing elements related to sexual aggression), risky sexual behavior, pornography use, religiosity, sexual self-esteem, and attitudes toward sexual coercion. These variables were used to predict sexual aggression perpetration and victimization reports obtained 12 months later (T2) for two time windows: (a) since the age of 15 until a year ago and (b) in the past year. As expected, risky sexual scripts were linked to risky sexual behavior and indirectly increased the likelihood of victimization in both time windows. Lower sexual self-esteem predicted sexual victimization since age 15, but not in the past 12 months. Pornography use and religiosity indirectly predicted victimization via risky scripts and behavior. Attitudes toward sexual coercion were a prospective predictor of sexual aggression perpetration. The results extend the international literature on sexual aggression and have implications for sexual education and sexual aggression prevention programs.

Sexual Assault and the Justice Gap
This book is set against the background of the 'justice gap' in sexual assault cases - the dramatic gap between the number of offences recorded by the police and the number of convictions. It seeks to examine the attitudinal problems which bedevil this area of law and possible strategies for addressing them. Written by a professor of law and a professor of psychology, it reviews evidence from socio-legal and social cognition research and presents new data drawn both from interviews with judges and barristers and from studies with prospective lawyers and members of the public. In the final part, it considers different ways in which rape trials could be improved and suggests steps that could be taken to change public attitudes about sexual assault.

Predicting Adolescents’ Self-Objectification from Sexualized Video Game and Instagram Use
A growing body of research has demonstrated negative effects of sexualization in the media on adolescents’ body image, but longitudinal studies and research including interactive and social media are scarce. The current study explored the longitudinal associations of adolescents’ use of sexualized video games (SVG) and sexualized Instagram images (SII) with body image concerns. Specifically, our study examined relations between adolescents’ SVG and SII use and appearance comparisons, thin- and muscular-ideal internalization, valuing appearance over competence, and body surveillance. A sample of 660 German adolescents (327 female, 333 male; Mage = 15.09 years) participated in two waves with an interval of 6 months. A structural equation model showed that SVG and SII use at Time 1 predicted body surveillance indirectly via valuing appearance over competence at Time 2. Furthermore, SVG and SII use indirectly predicted both thin- and muscular-ideal internalization through appearance comparisons at Time 1. In turn, thin-ideal internalization at Time 1 predicted body surveillance indirectly via valuing appearance over competence at Time 2. The results indicate that sexualization in video games and on Instagram can play an important role in increasing body image concerns among adolescents. We discuss the findings with respect to objectification theory and the predictive value of including appearance comparisons in models explaining the relation between sexualized media and self-objectification.

Romantic Attachment, Conflict Resolution Styles, and Teen Dating Violence Victimization
Although research on dating violence has increased in the last decades, little is known about the role of romantic attachment and conflict resolution in understanding victimization by an intimate partner among adolescents. This study examined the relationships between insecure attachment styles, destructive conflict resolution strategies, self-reported and perceived in the partner, and psychological and physical victimization by a dating partner in 1298 adolescents (49% girls). Anxious attachment was related to both forms of victimization via self-reported conflict engagement and conflict engagement attributed to the partner among boys and girls. Moreover, both insecure attachment styles were also indirectly linked to victimization via self-reported withdrawal and conflict engagement perceived in the partner, but only among boys. The implications of the findings for promoting constructive communication patterns among adolescents for handling their relationship conflicts are discussed.

Sexual Aggression among Women and Men in an Iranian Sample: Prevalence and Correlates
This pre-registered study examined the prevalence and correlates of sexual aggression in a sample of 530 Iranians (322 women, 208 men) with a behaviorally specific questionnaire distinguishing between different coercive strategies, victim-perpetrator relationships, and sexual acts. Significantly more women (63.0%) than men (51.0%) experienced at least one incident of sexual aggression victimization since the age of 15 years, and significantly more men (37.0%) than women (13.4%) reported at least one incident of sexual aggression perpetration. In women and men, the experience of child sexual abuse predicted sexual victimization and sexual aggression perpetration after the age of 15 years, both directly and indirectly through higher engagement in risky sexual behavior. Greater endorsement of hostile masculinity among men explained additional variance in the prediction of sexual aggression perpetration. This research is a first step towards documenting and explaining high rates of sexual aggression victimization and perpetration among Iranian women and men, providing important information for sex education as well for the prevention of sexual aggression. However, to achieve these goals, we highlight the need for systematic actions in all educational, social, and legal sectors of Iranian society.

Links of Perceived Pornography Realism with Sexual Aggression via Sexual Scripts, Sexual Behavior, and Acceptance of Sexual Coercion: A Study with German University Students
Exposure to pornographic material has been linked to sexual aggression perpetration and victimization in a large body of research. Based on social learning theory and 3A theory of script learning, this study contributes to this research by testing the hypothesis that the more realistic pornography is perceived to be by young adults, the more likely they are to experience and engage in sexual aggression. Two underlying pathways were proposed: one path via scripts and patterns of sexual behavior regarding consensual sexual interactions that contain established risk factors for sexual aggression victimization and perpetration, and a second path via the acceptance of sexual coercion. In a cross-sectional study, 1181 university students in Germany (762 female; 419 male) completed measures of pornography use and perception, risky sexual scripts and sexual behavior, and acceptance of sexual coercion. As predicted, pornography realism was a positive predictor of risky sexual scripts, risky sexual behavior, and acceptance of sexual coercion. Indirect links with sexual aggression victimization and perpetration were found via both pathways. No gender differences in the associations were found. The implications for media literacy interventions addressing the realism of pornography are discussed.

Speaking like a Man: Women’s Pitch as a Cue for Gender Stereotyping
Women’s average voice pitch has decreased in recent years, reducing the gap between men on this vocal dimension. The present study examined whether a woman speaking at a lower pitch would be perceived as less feminine and more masculine than a woman speaking at a higher pitch. Participants (n = 100, 67 female) listened to an audiotape of a woman in which her natural voice was manipulated to represent a pitch of either 220 Hz or 165 Hz. They then rated her on positive and negative facets of masculinity and femininity as well as competence and likeability. In addition, participants’ gendered self-concept was measured to examine potential moderator effects. As predicted, positive masculinity ratings were significantly higher, and positive and negative femininity ratings were significantly lower, in the 165 Hz than in the 220 Hz condition. The woman was also rated as more likeable in the 220 Hz than in the 165 Hz condition. No difference was found for negative masculinity and competence ratings, and no moderation effect of participants’ gendered self-concept emerged. The findings suggest that lower voice pitch is a masculinity cue that elicits stereotyped perceptions of female speakers and may have implications for impression formation in a variety of domains.
