如何应对社会排斥对于作为社会性动物的人类而言有着重要的适应性意义，以往研究表明在受到社会排斥时个体会调整对自己的认识。但是，社会排斥是会促进还是抑制自我反思加工、哪些因素在此过程中起到关键性作用，以及社会排斥对自我反思相关神经活动的调节在不同阶段具有哪些特征尚存在争议。为解决上述问题，项目组以行为学实验为基础，结合脑成像技术手段，探讨社会排斥影响自我反思加工的认知神经机制，揭示其中可能存在的文化差异，以及自我构念、自尊水平等相关因素的作用，阐明社会排斥对自我反思相关神经活动的调节在不同阶段所具有的特征，为构建一个较为完善的社会排斥影响自我反思模型提供更充分的科学依据。研究成果将有助于理解威胁性社会信息影响自我的本质机制，也将有助于人们在现实社会互动情境和教育实践中利用这些规律降低社会排斥的不利影响。项目组已开展了系列预实验，成员在相关领域有一定的前期工作基础，为项目的实施和完成提供了保障。

How humans deal with social exclusive signals is very important for their existence. Many previous studies have found that one's self-reflection can be affected by social exclusion from other person. However, (1) whether self-reflection can be promoted or suppressed by social exclusion, (2) which factors play a crucial role in this processing, and (3) social exclusion modulates self-reflection's neural activity have what characteristics in different stages, have not been established. Using behavioral experiments and functional magnetic resonance imaging technique, the present project aims to systematically address and investigate how social exclusion modulates self-reflection . The findings will extend cognitive and neural models of self-reflection to social threat contexts, and help public to minimize or avoid the adverse impact in the real social interaction situation and educational practice. We have collected and analyzed a series of pilot experiment data.
