愿意承担个人成本来执行亲社会规范是人类文明的一个标志。尽管最近的神经科学研究已经使用最后通牒游戏来理解公平规范实施背后的神经心理机制；然而，与公平相关的规范实施背后的神经系统的准确特征仍然难以捉摸。在这项研究中，我们使用了基于坐标的荟萃分析，对使用最后通牒游戏的功能磁共振成像(FMRI)研究进行了研究，目的是为完善这一人类令人费解的行为的潜在神经结构提供额外的证据。我们的结果表明，在与公平相关的标准化决策的心理成分相关的大脑网络中，报告的激活焦点集中在一起，可能反映了一个反身性和直觉的系统(系统1)和一个反思和深思熟虑的系统(系统2)。系统1(前脑岛、腹内侧前额叶皮质[PFC])可能与对违反规范的反射和直觉反应有关，代表了惩罚违反规范的人的动机。这些直觉反应与经济自利冲突，编码在背侧前扣带回皮质(ACC)，它可能从反射和刻意系统2进行认知控制，通过抑制(腹外侧PFC、背内侧PFC、左侧背外侧PFC和吻侧ACC)直觉反应或凌驾于自我利益之上(右侧背外侧PFC)来解决冲突。综上所述，我们建议与公平相关的规范执行招募一个直观的系统来快速评估违反规范的行为，并建立一个深思熟虑的系统来整合社会规范和自我利益，以调节直觉系统，有利于更灵活的决策。Hum Brain Mapp 36：591-602,2015。(C)2014年威利期刊公司。
The willingness to incur personal costs to enforce prosocial norms represents a hallmark of human civilization. Although recent neuroscience studies have used the ultimatum game to understand the neuropsychological mechanisms that underlie the enforcement of fairness norms; however, a precise characterization of the neural systems underlying fairness-related norm enforcement remains elusive. In this study, we used a coordinate-based meta-analysis on functional magnetic resonance imaging (fMRI) studies using the ultimatum game with the goal to provide an additional level of evidence for the refinement of the underlying neural architecture of this human puzzling behavior. Our results demonstrated a convergence of reported activation foci in brain networks associated with psychological components of fairness-related normative decision making, presumably reflecting a reflexive and intuitive system (System 1) and a reflective and deliberate system (System 2). System 1 (anterior insula, ventromedial prefrontal cortex [PFC]) may be associated with the reflexive and intuitive responses to norm violations, representing a motivation to punish norm violators. Those intuitive responses conflict with economic self-interest, encoded in the dorsal anterior cingulate cortex (ACC), which may engage cognitive control from a reflective and deliberate System 2 to resolve the conflict by either suppressing (ventrolateral PFC, dorsomedial PFC, left dorsolateral PFC, and rostral ACC) the intuitive responses or over-riding self-interest (right dorsolateral PFC). Taken together, we suggest that fairness-related norm enforcement recruits an intuitive system for rapid evaluation of norm violations and a deliberate system for integrating both social norms and self-interest to regulate the intuitive system in favor of more flexible decision making.
