人们对公平的积极情感影响或解决公平与经济利益之间冲突的过程知之甚少。在过去的研究中，公平性与金钱回报共变，这样的心理过程的基础偏好公平和那些潜在的偏好更大的金钱结果无法区分。我们检查了自我报告的幸福感和神经反应，同时控制了金钱回报。与同等金钱价值的不公平提议相比，公平的提议导致更高的幸福评级和大脑几个奖励区域的激活。此外，接受不公平提议的倾向与右腹外侧前额叶皮层（一个参与情绪调节的区域）的活动增加有关，与前额叶皮层的活动减少有关，前额叶皮层与负面情绪有关。这项工作提供的证据表明，公平是快乐的价值，容忍不公平的待遇，物质利益涉及一种激活模式类似于抑制负面影响。
Little is known about the positive emotional impact of fairness or the process of resolving conflict between fairness and financial interests. In past research, fairness has covaried with monetary payoff, such that the mental processes underlying preference for fairness and those underlying preference for greater monetary outcome could not be distinguished. We examined self-reported happiness and neural responses to fair and unfair offers while controlling for monetary payoff. Compared with unfair offers of equal monetary value, fair offers led to higher happiness ratings and activation in several reward regions of the brain. Furthermore, the tendency to accept unfair proposals was associated with increased activity in right ventrolateral prefrontal cortex, a region involved in emotion regulation, and with decreased activity in the anterior insula, which has been implicated in negative affect. This work provides evidence that fairness is hedonically valued and that tolerating unfair treatment for material gain involves a pattern of activation resembling suppression of negative affect.
