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.
虽然行为和实验研究表明受害与反社会行为之间存在关联，但解释这种关联的神经关联尚不清楚。在当前的研究中，我们招募了来自一项纵向研究的青少年女孩，该研究从第二年级到八年级每年跟踪青少年报告的同伴受害经历。根据这些报告，招募了 46 名青少年：25 名慢性受害和 21 名非受害。在功能磁共振成像扫描期间，参与者完成了一项风险承担任务。慢性同伴受害与任务中更大的冒险行为以及日常生活中更高水平的自我报告反社会行为有关。在神经水平上，慢性受害的女孩在涉及情感敏感性、社会认知和认知控制的区域表现出更高的激活水平，这显著介导了自我报告反社会行为中受害群体差异。
