Abstract: Fairness norm, as one of the most important social norms in social interaction, is widely shared sentiment about what constitutes appropriate behavior under specific social contexts. Given that social contexts play critical roles in fairness perception and fairness-related behaviors, they have been one of the central research topics in social and moral psychology. With the advances in neural imaging technology, psychologists and neuroscientists begin to look more closely into the neural basis of the effects of social contexts on fairness perception and fairness-related behaviors. Here we review the findings of this trend of research and point out some directions which will further our understanding of fairness norm, namely, combining computational modeling, molecular genetics, and neuroscience methods to reveal the computational, genetic and neural principles underlying the effects of social contexts on fairness perception and fairness-related behaviors.

Key words: social contexts, fairness norm, fairness perception, neural basis.

摘要： 公平作为人际交互中最重要的社会规范之一，是一种被普遍接受的关于群体成员在给定情境下应当如何行为的规范。社会情境对人际互动中的公平感知及相关行为具有重要的影响。本文结合前人研究，介绍近年来本实验室有关社会情境如何调节公平感知和相关行为的研究成果，并指出未来研究应结合计算模型、分子遗传学和神经科学手段，揭示公平感知与公平行为的计算、遗传和神经基础。
