道德认知与默认网络的激活有关，默认网络是涉及对自己的行为或他人意图进行精神化的区域。然而，人们对道德信息的最初探测知之甚少。我们考察了在叙事完成任务中道德加工的神经关联，其中包括内隐道德突显操纵。在功能磁共振扫描中，参与者阅读一个简短的小插曲，并从两个选项中选择语义最一致的句子来完成叙事。选项是不道德的、道德的或中立的声明。选择中性陈述的反应时最快，选择不道德陈述的反应时最慢。神经成像分析显示，涉及道德内容的反应涉及默认和执行控制网络大脑区域，包括内侧和头侧前额叶皮质，以及突出网络的核心区域，包括前岛和背侧前扣带回。不道德条件还参与了显著网络。这些结果表明，显著网络在道德信息的检测中可能会调节下游默认和前置控制网络的交互作用，为复杂的道德推理和决策过程服务。这些发现表明，道德认知既涉及自下而上的注意过程，也涉及自上而下的注意过程，由离散的大规模大脑网络及其相互作用调节。
Moral cognition is associated with activation of the default network, regions implicated in mentalizing about one’s own actions or the intentions of others. Yet little is known about the initial detection of moral information. We examined the neural correlates of moral processing during a narrative completion task, which included an implicit moral salience manipulation. During fMRI scanning, participants read a brief vignette and selected the most semantically congruent sentence from two options to complete the narrative. The options were immoral, moral or neutral statements. RT was fastest for the selection of neutral statements and slowest for immoral statements. Neuroimaging analyses revealed that responses involving morally laden content engaged default and executive control network brain regions including medial and rostral prefrontal cortex, and core regions of the salience network, including anterior insula and dorsal anterior cingulate. Immoralvsmoral conditions additionally engaged the salience network. These results implicate the salience network in the detection of moral information, which may modulate downstream default and frontal control network interactions in the service of complex moral reasoning and decision-making processes. These findings suggest that moral cognition involves both bottom-up and top-down attentional processes, mediated by discrete large-scale brain networks and their interactions.
