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.

道德认同个体差异的神经相关性及其积极的道德功能。
道德认同是一个重要的道德变量,具有积极的道德功能,如促进亲社会行为、减少反社会行为和抵制反社会行为的风险因素。然而,人们对道德认同的神经相关性以及道德认同影响反社会行为风险因素(包括道德脱离)的神经基础知之甚少。在这项研究中,我们通过静息态功能磁共振成像(fMRI)估算了142名大学生的区域同质性(ReHo),从而对这些问题进行了探讨。全脑相关分析发现,较高的内化道德认同与较高的楔前区ReHo相关。此外,楔前区的 ReHo 与道德脱离呈负相关,表明道德认同的神经机制具有积极的道德功能。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教育和道德脱离干预提供了启示。

期刊介绍: The Journal of Neuropsychology publishes original contributions to scientific knowledge in neuropsychology including: • clinical and research studies with neurological, psychiatric and psychological patient populations in all age groups • behavioural or pharmacological treatment regimes • cognitive experimentation and neuroimaging • multidisciplinary approach embracing areas such as developmental psychology, neurology, psychiatry, physiology, endocrinology, pharmacology and imaging science The following types of paper are invited: • papers reporting original empirical investigations • theoretical papers; provided that these are sufficiently related to empirical data • review articles, which need not be exhaustive, but which should give an interpretation of the state of research in a given field and, where appropriate, identify its clinical implications • brief reports and comments • case reports • fast-track papers (included in the issue following acceptation) reaction and rebuttals (short reactions to publications in JNP followed by an invited rebuttal of the original authors) • special issues.
