孤独是一种因缺乏令人满意的社会关系而产生的痛苦感觉。孤独在现代社会中越来越普遍，并对健康和幸福产生不利影响。尽管对社会关系的情境威胁可以短暂地诱发孤独情绪，但对孤独的敏感性是一种稳定的特征，因人而异，并且在某种程度上是可遗传的。然而，人们对与孤独相关的神经过程知之甚少（但请参阅）。在这里，我们假设孤独感的个体差异可能反映在与社会过程相关的大脑区域的结构中。为了验证这一假设，我们使用基于体素的形态测量法，结果表明孤独个体的左后颞上沟（pSTS）——一个与基本社会感知有关的区域——的灰质较少。正如这一发现所预测的，我们进一步证实孤独与处理社交线索的困难有关。尽管社交网络规模、焦虑和同理心等其他社会心理因素独立地导致孤独感，但只有基本的社会感知技能介导了 pSTS 量和孤独感之间的关联。综上所述，我们的结果表明，基本的社会感知能力在塑造个人的孤独感方面发挥着重要作用。 ► 孤独感与颞上沟 (pSTS) 的体积相关 ► pSTS 体积预测识别社交信号的能力 ► 孤独者难以识别眼睛注视方向 ► 社交网络规模、焦虑和同理心也会影响孤独感
Loneliness is the distressing feeling associated with the perceived absence of satisfying social relationships. Loneliness is increasingly prevalent in modern societies and has detrimental effects on health and happiness. Although situational threats to social relationships can transiently induce the emotion of loneliness, susceptibility to loneliness is a stable trait that varies across individuals and is to some extent heritable. However, little is known about the neural processes associated with loneliness (but see). Here, we hypothesized that individual differences in loneliness might be reflected in the structure of the brain regions associated with social processes. To test this hypothesis, we used voxel-based morphometry and showed that lonely individuals have less gray matter in the left posterior superior temporal sulcus (pSTS)—an area implicated in basic social perception. As this finding predicted, we further confirmed that loneliness was associated with difficulty in processing social cues. Although other sociopsychological factors such as social network size, anxiety, and empathy independently contributed to loneliness, only basic social perception skills mediated the association between the pSTS volume and loneliness. Taken together, our results suggest that basic social perceptual abilities play an important role in shaping an individual’s loneliness. ► Loneliness is correlated with the volume of posterior superior temporal sulcus (pSTS) ► The pSTS volume predicted the ability to recognize social signals ► Lonely individuals have difficulty in recognizing eye gaze direction ► Social network size, anxiety, and empathy also shape loneliness
