Chronic peer victimization heightens neural sensitivity to risk taking / Eva H. TELZER in Development and Psychopathology, 30-1 (February 2018)

TELZER, Auteur ; Michelle E. MIERNICKI, Auteur ; Karen D. RUDOLPH, Auteur Article en page(s) : p.13-26 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Although behavioral and experimental studies have shown links between victimization and antisocial behavior, the neural correlates explaining this link are relatively unknown. In the current study, we recruited adolescent girls from a longitudinal study that tracked youths’ reports of peer victimization experiences annually from the second through eighth grades. Based on these reports, 46 adolescents were recruited: 25 chronically victimized and 21 nonvictimized. During a functional magnetic resonance imaging scan, participants completed a risk-taking task. Chronic peer victimization was associated with greater risk-taking behavior during the task and higher levels of self-reported antisocial behavior in everyday life. At the neural level, chronically victimized girls showed greater activation in regions involved in affective sensitivity, social cognition, and cognitive control, which significantly mediated victimization group differences in self-reported antisocial behavior.

Moving against and away from the world: The adolescent legacy of peer victimization / Karen D. RUDOLPH in Development and Psychopathology, 26-3 (August 2014)  

Public ISBD [article]  inDevelopment and Psychopathology > 26-3 (August 2014) . - p.721-734 Titre : Moving against and away from the world: The adolescent legacy of peer victimization Type de document : Texte imprimé et/ou numérique Auteurs : Karen D. RUDOLPH, Auteur ; Wendy TROOP-GORDON, Auteur ; Jennifer D. MONTI, Auteur ; Michelle E. MIERNICKI, Auteur Article en page(s) : p.721-734 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Nicki Crick initiated a generative line of theory and research aimed at exploring the implications of exposure to overt and relational aggression for youth development. The present study aimed to continue and expand this research by examining whether early (second grade) and increasing (second–sixth grade) levels of victimization during elementary school contributed to youths’ tendencies to move against, away from, or toward the world of peers following the transition to middle school. Youth (M age in second grade = 7.96 years, SD = 0.35; 338 girls, 298 boys) reported on their exposure to victimization and their social goals (performance-approach, performance-avoidance, or mastery). Teachers reported on youths’ exposure to victimization and their engagement in antisocial, socially helpless, and prosocial behavior. Latent growth curve analyses revealed that early and increasing levels of both overt and relational victimization uniquely contributed to multifinality in adverse developmental outcomes, predicting all three social orientations (high conflictual engagement, high disengagement, and low positive engagement). The pattern of effects was robust across sex and after adjusting for youths’ early social motivation. These findings confirm that both forms of victimization leave an enduring legacy on youths’ social health in adolescence. Given that profiles of moving against and away from the world can contribute to subsequent psychopathology, understanding and preventing this legacy is pivotal for developing effective intervention programs aimed at minimizing the effects of peer adversity.
