人类物种的一个独特特征是遵守社会规范，例如，公平，尽管这一规范性决定意味着抑制自身利益。然而，有时人们宁愿以牺牲道德善良为代价来追求财富。具体而言，偏离公平相关的规范性选择已被观察到的存在下，一个高的货币激励。这种偏离与公平相关的规范性选择的神经机制尚未确定。为了解决这个问题，使用功能性磁共振成像，我们采用了最后通牒游戏（UG）的范式，其中公平性和建议的货币金额正交变化。我们发现，在右侧前额叶皮层（PFC）和双侧岛叶皮层中，提议的公平性金额有显著的调节作用。此外，岛叶亚区表现出可分离的调制模式。在左额下回（IFG）的调制效果的个体间差异占的行为调制效果的个体间差异所测量的拒绝率，支持的概念，即PFC起着至关重要的作用，在社会互动条件下作出公平相关的规范性决策。我们的研究结果提供了神经证据的公平性的调制货币激励，以及占个体间的差异。
A unique feature of the human species is compliance with social norms, e.g., fairness, even though this normative decision means curbing self-interest. However, sometimes people prefer to pursue wealth at the expense of moral goodness. Specifically, deviations from a fairness-related normative choice have been observed in the presence of a high monetary incentive. The neural mechanism underlying this deviation from the fairness-related normative choice has yet to be determined. In order to address this issue, using functional magnetic resonance imaging we employed an ultimatum game (UG) paradigm in which fairness and a proposed monetary amount were orthogonally varied. We found evidence for a significant modulation by the proposed amount on fairness in the right lateral prefrontal cortex (PFC) and the bilateral insular cortices. Additionally, the insular subregions showed dissociable modulation patterns. Inter-individual differences in the modulation effects in the left inferior frontal gyrus (IFG) accounted for inter-individual differences in the behavioral modulation effect as measured by the rejection rate, supporting the concept that the PFC plays a critical role in making fairness-related normative decisions in a social interaction condition. Our findings provide neural evidence for the modulation of fairness by monetary incentives as well as accounting for inter-individual differences.
