Neural correlates of social-cognition were assessed in 9- to- 17-year-olds (N = 34) using functional magnetic resonance imaging. Participants appraised how unfamiliar peers they had previously identified as being of high or low interest would evaluate them for an anticipated online chat session. Differential age- and sex-related activation patterns emerged in several regions previously implicated in affective processing. These included the ventral striatum, hippocampus, hypothalamus, and insula. In general, activation patterns shifted with age in older relative to younger females but showed no association with age in males. Relating these neural response patterns to changes in adolescent social-cognition enriches theories of adolescent social development through enhanced neurobiological understanding of social behavior.
利用功能磁共振成像技术,对9至17岁的青少年(N = 34)的社会认知神经关联进行了评估。参与者评估了他们之前认定为高兴趣或低兴趣的陌生同龄人会如何评价他们即将进行的在线聊天。在先前与情感处理相关的几个区域出现了与年龄和性别相关的不同激活模式。这些区域包括腹侧纹状体、海马体、下丘脑和脑岛。总体而言,老年女性相对于年轻女性的激活模式随年龄变化,而男性的激活模式与年龄无关。将这些神经反应模式与青少年社会认知的变化联系起来,通过增强对社会行为的神经生物学理解,丰富了青少年社会发展理论。
