这项功能性磁共振成像（fMRI）研究探讨了青少年（12-15岁）对社会排斥的主观和神经反应，这些青少年在6至12岁的同龄人中具有稳定的接受（n = 27; 14名男性）或慢性拒绝（n = 19; 12名男性）状态。这两组青少年在被排除在一个虚拟的投球游戏（Cyberball）之后，都报告了类似的痛苦增加，但是有慢性同伴排斥史的青少年在以前与检测相关的大脑区域中表现出更高的活动，以及由社会排斥引起的痛苦。具体而言，与稳定接受的青少年相比，长期拒绝的青少年表现出：1）在社会排斥期间，背侧前扣带皮层（dACC）的活动更高; 2）当他们偶然被排除在社会交往中时，dACC和前额叶皮层的活动更高。这些研究结果表明，慢性童年同伴排斥与青春期社会排斥的神经反应增强有关，这对理解同伴排斥可能导致心理健康随着时间的推移产生不利影响的过程具有影响。本文的在线版本（doi：10.1007/s10802-015-9983-0）包含补充材料，可供授权用户使用。
This functional Magnetic Resonance Imaging (fMRI) study examined subjective and neural responses to social exclusion in adolescents (age 12–15) who either had a stable accepted (n = 27; 14 males) or a chronic rejected (n = 19; 12 males) status among peers from age 6 to 12. Both groups of adolescents reported similar increases in distress after being excluded in a virtual ball-tossing game (Cyberball), but adolescents with a history of chronic peer rejection showed higher activity in brain regions previously linked to the detection of, and the distress caused by, social exclusion. Specifically, compared with stably accepted adolescents, chronically rejected adolescents displayed: 1) higher activity in the dorsal anterior cingulate cortex (dACC) during social exclusion and 2) higher activity in the dACC and anterior prefrontal cortex when they were incidentally excluded in a social interaction in which they were overall included. These findings demonstrate that chronic childhood peer rejection is associated with heightened neural responses to social exclusion during adolescence, which has implications for understanding the processes through which peer rejection may lead to adverse effects on mental health over time.
