社会比较影响公平决策的神经机制研究

In social comparison, different reference groups can lead to different standards and results of fairness judgment, which further affects fairness decision making. Through research on how neural mechanism influence social comparison on fair decision making under three conditions (self-reference, proposer-reference and multiple-reference), this project reveals that social comparison can affect fairness decision making. The project also verifies the relative standing model of fairness. These discussions not only contribute to answer basic scientific problems about social comparison’s influence on fair decision making, further develop the theory of fairness, improve settlements of fairness issues, but also benefit to screen/intervene some psychiatric/neurological disorders in early phase. Most of previous studies are phenomenological descriptions for fairness decision making under proposer-reference, leaving a lack for related studies in neural mechanism. Start from different conditions of reference groups, using a combination of behavioral testing, electrophysiology and functional brain imaging, this project try to answer two questions: 1) self-reference’s influence on fairness decision making in comparison with proposer-reference’s; 2) multiple-reference’s influence on fairness decision making under multiple-proposers’ and multiple-responders’ conditions. So far, the research platform has been set up, and the project team is exceled at related technics and contrast effects’ influence on decision making, which builds a solid foundation for the implementation and accomplishment of this project.

社会比较的参照对象不同会使公平判断产生不同标准和结果，进而影响公平决策。本项目通过研究自我参照、他人参照和多重参照条件下社会比较影响公平决策的神经机制，揭示社会比较能够影响公平决策，并验证公平的相对地位模型。这些探讨，不仅有助于回答社会比较影响公平决策的基本科学问题，进一步完善公平理论，促进公平问题解决，也有助于早期筛查/干预一些精神/神经疾患。以往研究大多对他人参照公平决策进行现象学描述，缺乏公平决策神经机制研究。本项目从不同层次的参照对象入手，综合运用行为测量、脑电和脑成像等技术手段，试图回答：1）自我参照相比他人参照对公平决策的影响；2）分配多人和多人分配的多重参照对公平决策的影响。当前，项目平台已经搭建，项目组成员在技术、对比效应影响决策等方面有很好的工作基础，为本项目的实施和完成提供了保障。
