Abstract：
Moral identity is an important moral variable which has positive moral functions, such as contributing to prosocial behaviours, reducing antisocial behaviours, and resisting the risk factors of antisocial behaviours. However, little is known about the neural correlates of moral identity and the neural basis of the effect of moral identity on the risk factors of antisocial behaviours, including moral disengagement. In this study, we explored these issues in 142 college students by estimating the regional homogeneity (ReHo) through resting-state functional magnetic resonance imaging (fMRI). The whole-brain correlation analyses found that higher internalized moral identity was correlated with higher ReHo in the precuneus. Furthermore, the ReHo in the precuneus was negatively correlated with moral disengagement, suggesting positive moral functions of the neural mechanisms of moral identity. These findings deepen our understanding of individual differences in moral identity and provide inspiration for the education of moral identity and the intervention for moral disengagement from the perspective of the brain.
摘要：
道德认同是一个重要的道德变量,具有积极的道德功能,比如促进亲社会行为，减少反社会行为，抵制反社会行为的危险因素。然而,关于道德认同的神经相关性以及道德认同对反社会行为风险因素影响的神经基础知之甚少，包括道德上的脱离。在这项研究中,我们通过静息态功能磁共振成像(fMRI)估计区域同质性(ReHo),在142名大学生中探讨了这些问题.全脑相关性分析发现，较高的内在化道德认同与前突中较高的ReHo相关。此外，前尾处的ReHo与道德脱离负相关，表明道德认同的神经机制的积极道德功能。这些发现加深了我们对道德认同个体差异的理解，并从大脑的角度为道德认同的教育和道德脱离的干预提供了启示。
