使用功能磁共振成像对 9 至 17 岁儿童（N = 34）的社会认知神经相关性进行评估。参与者评估了他们之前认为兴趣高或兴趣低的不熟悉的同伴会如何评价他们对预期的在线聊天会话的评价。在先前与情感处理有关的几个区域中出现了与年龄和性别相关的不同激活模式。这些包括腹侧纹状体、海马、下丘脑和岛叶。一般来说，相对于年轻女性，老年女性的激活模式随着年龄的增长而变化，但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的理论。
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.
