Abstract:Peer victimization is associated with increased risk for mental health problems. These adverse psychological outcomes are linked with altered cognitive and emotional processes and their related neural functioning. In the present study, by using functional magnetic resonance imaging (fMRI), we examined whether peer victimization was associated with heightened neural response to social exclusion. Participants (N = 45; Mage = 17.7 years, SD = 0.60; 36 women) included three mutually exclusive groups: peer-victimized individuals (targets of bullying), cyberdefenders (defended peers who were being cyberbullied), and controls (not involved as targets or cyberdefenders). All participants underwent an fMRI scan while playing Cyberball, an experimental paradigm that simulates social exclusion. Peer victimization was associated with increased neural response in the left amygdala, left parahippocampal gyrus, left inferior frontal operculum, and right fusiform gyrus. Understanding the acute neural response to social exclusion in peer-victimized individuals may provide insight into their increased risk for poor mental health.

同伴受害与对社会排斥的神经反应有关

摘要：同伴受害与精神健康问题的风险增加有关。这些不良的心理结果与认知和情感过程及其相关神经功能的改变有关。在本研究中，通过使用功能磁共振成像（fMRI），我们检查了同伴受害是否与社会排斥的神经反应增强有关。参与者（N = 45；法师= 17.7年，SD = 0.60； 36位女性）包括三个相互排斥的群体：同龄受害人（欺凌的目标），网络维护者（被网络欺凌的被保护的同龄人）和控制者（不参与目标或网络防御者）。所有参与者在玩“ Cyber​​ball”时都进行了功能磁共振成像扫描，这是一种模拟社交排斥的实验范式。同伴受害与左杏仁核，左海马旁回，额下和右梭状回的神经反应增强有关。了解在同龄被害者中对社会排斥的急性神经反应可能会为他们增加不良精神健康风险提供见解。
