以前的神经影像学研究的场景，如囚犯的困境和最后通牒游戏显示，大脑系统的发展过程中，奖励和厌恶刺激的激活差异在遵守和违反规范。关于共享的社会规范如何演变的一个理论是，它们产生于相互奖励的惯例，这些惯例通过反复执行，获得了一种规范价值，即使在个人私利得不到满足的情况下，也能维持社会凝聚力。作者报告了一项2人协调游戏的功能磁共振成像研究，在该游戏中，玩家必须按照任意约定（按下左或右按钮）进行协调，以获得金钱奖励。一旦这个约定建立起来，其中一个参与者就会受到激励，偏离均衡，并提供额外的奖励。在决定违反惯例之前的一段时间里，在与奖励处理相关的区域（如中脑、尾状核和眶额皮质）观察到活动。在决定继续协调之前，杏仁核和前岛叶-额下回被激活。数据进行了讨论，提出了在人类大脑中存在多个相互作用的基于价值的决策系统的理论。（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
Previous neuroimaging studies of scenarios such as the prisoner's dilemma and ultimatum game show how brain systems which evolved to process rewarding and aversive stimuli are activated differentially during adherence to and breaches of norms. One theory of how shared social norms evolve is that they arise from mutually rewarding conventions which, through repeated execution, acquire a normative value that sustains social cohesion even when individual self-interest is not served. The authors report an fMRI study of a 2-player coordination game in which players must coordinate on an arbitrary convention (a left or right button press) to obtain monetary rewards. Once this convention has been established, one of the participants is incentivized to deviate from the equilibrium with the offer of extra reward. During the period prior to decisions to violate the convention, activity was observed in regions associated with reward processing, such as the midbrain, caudate, and orbitofrontal cortex. Activations in advance of decisions to continue coordinating included the amygdala and anterior insula–inferior frontal gyrus. The data are discussed in the light of theories which propose the existence of multiple interacting value-based decision-making systems in the human brain.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
