道德是人类文化的基本组成部分，被定义为关于人们应该如何对待彼此的规范性规范，包括正义、公平和权利等概念。这项研究使用功能磁共振成像技术，研究了在多大程度上，正义敏感度倾向(即个体对不公正和不公平经历的反应)预测了赞扬和指责的行为评级，以及当参与者评估道德含量高的(好的和坏的)日常行为时，它们如何调节在线神经反应和功能连通性。正义敏感性并不影响动作观察网络中的神经血流动力学反应，而是影响了右侧顶叶交界处(RTPJ)、右侧背外侧和背内侧前额叶皮质(rDLPFC，dmPFC)中处理心理状态理解和维持目标表征的高阶计算节点。这些地区的活动预测了赞扬和指责的评级。此外，rTPJ的血流动力学反应在rDLPFC的反应之前表现出良好和不良反应的分化。2 S。对良好行为的评估特别与背侧纹状体的活动增强以及rTPJ和前扣带皮质之间的功能耦合增加有关。总而言之，这项研究提供了关于个体正义敏感性的差异如何影响神经计算的重要知识，神经计算支持涉及道德判断和精神状态推理的心理过程。
Morality is a fundamental component of human cultures and has been defined as prescriptive norms regarding how people should treat one another, including concepts such as justice, fairness, and rights. Using fMRI, the current study examined the extent to which dispositions in justice sensitivity (i.e., how individuals react to experiences of injustice and unfairness) predict behavioral ratings of praise and blame and how they modulate the online neural response and functional connectivity when participants evaluate morally laden (good and bad) everyday actions. Justice sensitivity did not impact the neuro-hemodynamic response in the action-observation network but instead influenced higher-order computational nodes in the right temporoparietal junction (rTPJ), right dorsolateral and dorsomedial prefrontal cortex (rdlPFC, dmPFC) that process mental states understanding and maintain goal representations. Activity in these regions predicted praise and blame ratings. Further, the hemodynamic response in rTPJ showed a differentiation between good and bad actions 2 s before the response in rdlPFC. Evaluation of good actions was specifically associated with enhanced activity in dorsal striatum and increased the functional coupling between the rTPJ and the anterior cingulate cortex. Together, this study provides important knowledge in how individual differences in justice sensitivity impact neural computations that support psychological processes involved in moral judgment and mental-state reasoning.
