人类被驱使去追求和维护社会关系，这些动机通过生物系统得到加强。特别是，应对社会威胁的生物系统调节的个体差异可能促使个体寻求结构不同的社会环境。我们选取了74名接受功能磁共振成像（fMRI）脑成像并提供Facebook数据的青少年男性作为样本，研究了对一种常见情况（被同龄人排除在外）的生理反应是否与他们的社交网络结构有关。我们发现，在社会排斥期间，大脑中先验假设的“社会痛苦”区域（dACC、AI、subACC）的神经反应与核心友谊网络的密度和传递性有关。这些发现表明，对排斥的神经反应可能是网络“安全”背后的一个因素。更广泛地说，这项研究显示了将社会认知倾向与社会结构属性联系起来的潜力。
Humans are driven to pursue and preserve social relationships, and these motivations are reinforced through biological systems. In particular, individual differences in the tuning of biological systems that respond to social threats may motivate individuals to seek out differently structured social environments. Drawing on a sample of adolescent males who underwent fMRI brain imaging (n = 74) and contributed Facebook data, we examined whether biological responses to a common scenario – being excluded from an activity with peers – was associated with their social network structure. We find that neural responses during social exclusion in a priori hypothesized “social pain” regions of the brain (dACC, AI, subACC) are associated with the density and transitivity of core friendship networks. These findings suggest that neural reactivity to exclusion may be one factor that underlies network “safety”. More broadly, the study shows the potential of linking social cognitive tendencies to social structural properties.
