在本研究中，我们探讨了社会情感脑系统的发展调制与青少年社会评价的关系。儿童，青少年和成年人的参与者看到的线索表明，相机交替关闭，热身，或投影他们的形象，以同行在收购的行为，自主神经和神经反应（功能性MRI）数据。相信一个同伴正在积极地观察他们，这足以引起青少年比儿童和成人更强烈的自我意识情绪。自主唤醒在青少年中是独一无二的。这些行为模式被青春期内侧前额叶皮层（MPFC）和纹状体-MPFC连接的紧急参与所取代，这被认为是促进自发动机的社会行为。这些研究结果表明，青少年的自我意识是与年龄相关的敏感性的大脑系统的社会情感过程的关键。此外，MPFC和纹状体之间独特的相互作用可能提供了一种机制，社会评价环境影响青少年的行为。
In the present study, we examined the relationship between developmental modulation of socioaffective brain systems and adolescents’ preoccupation with social evaluation. Child, adolescent, and adult participants viewed cues indicating that a camera was alternately off, warming up, or projecting their image to a peer during the acquisition of behavioral-, autonomic-, and neural-response (functional MRI) data. Believing that a peer was actively watching them was sufficient to induce self-conscious emotion that was stronger in adolescents than in children and adults. Autonomic arousal was uniquely heightened in adolescents. These behavioral patterns were paralleled by emergent engagement of the medial prefrontal cortex (MPFC) and striatum-MPFC connectivity during adolescence, which are thought to promote adolescent-motivated social behavior. These findings demonstrate that adolescents’ self-consciousness is related to age-dependent sensitivity of brain systems critical to socioaffective processes. Further, unique interactions between the MPFC and striatum may provide a mechanism by which social-evaluation contexts influence adolescent behavior.
