Abstract:The goal of this study was to examine how individual differences in physiological arousal and reactivity moderated the relation between peer victimization and reactive and proactive aggression. Participants were 58 adolescents (61.2% boys; 54.9% African American) in the age range of 12–15. Participants self-reported peer victimization, reactive aggression, and proactive aggression. Cortisol and respiratory sinus arrhythmia (RSA) were measured from participants before and during an online game in which they were socially rejected by unfamiliar peers. Results indicated that the relation between peer victimization with reactive aggression was significant and positive at low levels of resting RSA and when RSA withdrawal after rejection was high. The association between peer victimization with reactive and proactive aggression was also significant and positive at high levels of anticipatory cortisol. Findings provide further insight into the moderating role that physiological processes may have in understanding individual differences to peer adversity.

受到同龄人的攻击和攻击性：生理唤醒和反应性的调节作用

摘要：本研究的目的是研究生理唤醒和反应性的个体差异如何缓解同伴受害与反应性和主动性侵略之间的关系。参与者为12至15岁的58名青少年（男孩为61.2％；非洲裔美国人为54.9％）。参与者自我报告同伴受害，反应性侵略和积极侵略。在进行在线游戏之前和期间，从参与者中测量了皮质醇和呼吸窦性心律失常（RSA），在社交游戏中，陌生人拒绝了他们。结果表明，同伴受害与反应性攻击之间的关系在低水平的静止RSA以及排斥后RSA退出较高时呈正相关。在预期的皮质醇水平较高时，同伴受害与反应性和主动性侵略之间的关联也很明显且呈正相关。这些发现为生理过程在理解同伴逆境的个体差异中可能起的调节作用提供了进一步的见解。
