尽管神经科学越来越关注人类决策的神经基础，但对社会环境下的决策的关注相对较少。此外，虽然人类社会决策已经在社会心理学的背景下进行了探索，但很少考虑到观察到的结果的神经解释。为了弥补这一差距并改进人类社会决策模型，我们研究了获得良好声誉是否会激活与金钱奖励相同的奖励回路。声誉是人类社会行为的重要激励因素。总共有19名受试者参加了涉及金钱和社会奖励的功能磁共振成像（fMRI）实验。当一个人获得好名声时，会强烈地激活与奖励相关的大脑区域，尤其是纹状体，这些区域与金钱奖励激活的区域重叠。我们的发现支持了奖励的“共同神经货币”的观点，并代表了对复杂的人类社会行为进行神经解释的重要的第一步。
Despite an increasing focus on the neural basis of human decision making in neuroscience, relatively little attention has been paid to decision making in social settings. Moreover, although human social decision making has been explored in a social psychology context, few neural explanations for the observed findings have been considered. To bridge this gap and improve models of human social decision making, we investigated whether acquiring a good reputation, which is an important incentive in human social behaviors, activates the same reward circuitry as monetary rewards. In total, 19 subjects participated in functional magnetic resonance imaging (fMRI) experiments involving monetary and social rewards. The acquisition of one's good reputation robustly activated reward-related brain areas, notably the striatum, and these overlapped with the areas activated by monetary rewards. Our findings support the idea of a "common neural currency" for rewards and represent an important first step toward a neural explanation for complex human social behaviors.
