社会接受度对于健康运作至关重要。我们使用功能性磁共振成像（fMRI）来检查与年龄相关的社会接受和拒绝处理神经相关的变化。来自四个年龄组的参与者参加了这项研究：青春期前儿童（8-10岁），早期青少年（12-14岁），老年青少年（16-17岁）和年轻人（19-25岁）。在实验过程中，参与者面对不熟悉的同龄人面孔，并被要求预测他们是否期望被另一个人喜欢或不喜欢，然后是表示接受或拒绝的反馈。结果表明，激活腹侧mPFC和纹状体的社会反馈是依赖于上下文的，有增加激活时，参与者有积极的期望社会评价，并增加激活后的社会接受反馈。与年龄相关的比较显示，随着年龄的增长，这些大脑区域的活动呈线性增长，对社会评价有积极的期望。同样，随着年龄的增长，发现在纹状体，腹侧mPFC，OFC，和外侧PFC的拒绝反馈激活的线性增加。没有年龄相关的差异，在神经激活的社会接受反馈。总之，这些结果为涉及社会和情感行为的大脑区域的发展轨迹提供了重要的见解。
Social acceptance is of key importance for healthy functioning. We used functional magnetic resonance imaging (fMRI) to examine age-related changes in the neural correlates of social acceptance and rejection processing. Participants from four age groups participated in the study: pre-pubertal children (8-10 years), early adolescents (12-14 years), older adolescents (16-17 years) and young adults (19-25 years). During the experiment, participants were presented with unfamiliar faces of peers and were asked to predict whether they expected to be liked or disliked by the other person, followed by feedback indicating acceptance or rejection. Results showed that activation in the ventral mPFC and striatum to social feedback was context-dependent; there was increased activation when participants had positive expectations about social evaluation, and increased activation following social acceptance feedback. Age-related comparisons revealed a linear increase in activity with age in these brain regions for positive expectations of social evaluation. Similarly, a linear increase with age was found for activation in the striatum, ventral mPFC, OFC, and lateral PFC for rejection feedback. No age-related differences in neural activation were shown for social acceptance feedback. Together, these results provide important insights in the developmental trajectories of brain regions implicated in social and affective behavior.
