亲社会行为是青少年社会化的一个重要任务，也是我国社会主义核心价值观的要求，同时青少年的亲社会行为表现也是评价其人格健全与否的一个重要指标。青少年亲社会行为的影响因素是多方面的，而自我控制是最重要的因素之一。近期研究已经发现自我控制水平较高的个体表现出更多的亲社会行为，但其中的具体机制则尚未被深入揭示。本课题将采用自我报告、他人报告、经验取样、行为实验以及事件相关电位等方法综合考察青少年自我控制影响亲社会行为的心理以及神经机制，具体内容包括：（1）探讨青少年自我控制影响亲社会行为的心理机制（包括认知机制与情绪机制）；（2）探究自我控制影响亲社会行为的大脑动态时程，以及从纵向发展的视角，揭示青少年自我控制相关的脑电成分对亲社会行为的预测作用。本课题对推动青少年自我控制功能的理论研究以及揭示亲社会行为的心理与神经机制具有重要的创新意义，也可为培养和发展青少年的亲社会行为提供有价值的科学依据。

Adolescents’ development of prosocial behavior is a major task of socialization and also one of the requirements of socialistic core values. It is a crucial indicator of adolescents’ personality functioning as well. Adolescents’ prosocial behavior is affected by a number of factors; one of such variables is self-control. Recent studies have found that individuals with high levels of self-control engage in more prosocial behavior, but the underlying mechanism has not received systematic research. The current project aims to investigate how adolescents’ self-control level influences their prosocial behavior using various methods including self-report, other-report, experience sampling method, behavioral experiment and event-related potentials technique. Specifically, two broad questions will be examined: (1) explore the cognitive and emotional mechanisms of the link of self-control and prosocial behavior; and (2) explore the neural mechanism of this link by testing to which extent the neural potentials related to self-control are associated with and predict subsequent prosocial decision and behavior. The expected findings are meaningful to disclose the function of adolescents’ self-control and bear novel significance in revealing the psychological and neural mechanisms of how adolescents’ self-control is associated with prosocial behavior. Moreover, it lays the scientific foundation for cultivation and intervention of adolescent prosocial behavior.
