Belonging to a social group is one of the most important factors contributing to well-being. The Belonging Regulation model proposes that humans possess a social monitoring system (SMS) that evaluates social inclusion and monitors belonging needs. Here, we used a prospective longitudinal design to examine links between peer victimization experienced across 7 years and social monitoring at the behavioral and neural level in adolescent girls (n = 38, Mage = 15.43 years, SD = .33). Participants completed a social evaluation task during a functional magnetic resonance imaging (fMRI) scan. More severe peer victimization was associated with increased activation to in-group versus out-group peers in the amygdala, ventral striatum, fusiform gyrus, and temporoparietal junction. Moreover, participants who displayed increased activation in these regions reported lower social self esteem and higher levels of internalizing and externalizing symptoms. These results suggest that exposure to peer victimization across the school years is associated with heightened social monitoring at the neural level during adolescence, which has potential adverse implications for girls' adjustment and well-being.
属于一个社会群体是幸福感的最重要因素之一。归属感调节模型提出，人类拥有一个社会监测系统 (SMS)，用于评估社会包容度并监测归属感需求。在这里，我们采用前瞻性纵向设计，研究了青少年女孩在 7 年内经历的同伴侵害与行为和神经水平的社会监测之间的联系（n=38，平均年龄=15.43 岁，标准差=.33）。参与者在功能磁共振成像 (fMRI) 扫描期间完成了一项社会评估任务。更严重的同伴侵害与杏仁核、腹侧纹状体、梭状回和颞顶联合区对同组与异组同伴的激活增加有关。此外，在这些区域显示出更高激活的参与者报告了更低的社会自尊和更高的内化和外化症状水平。这些结果表明，在整个学年中暴露于同伴侵害与青春期时神经水平的社会监测增强有关，这对女孩的适应和幸福感可能产生不利影响。
