先前的研究表明，直觉道德认知发生在早期阶段。然而，不一致的研究结果表明，道德信息是在一个相对较晚的阶段。本研究以再认电位（RP）为神经指标，同时使用道德基础问卷测量个体的道德偏好。我们的目的是调查如何在道德偏好的个体差异调节加工的道德在前语义阶段，并提供一些见解来解释的变化，在快速信息处理与道德。参与者执行了一项内隐任务，其中描述地理名称或与道德、恶心或中性内容相关的行为的可识别词语与背景刺激以高呈现率交替出现。结果表明，早期识别的道德信息表现在RP依赖于个人的道德关注。参与者与更高水平的认可的伤害/护理基金会表现出更大的净道德效应，即更大的平均振幅的道德中性RP差异波。与此同时，只有对伤害/护理基金会更敏感的一组对道德词的RP明显大于中性词。总的来说，这些发现表明，道德认知的早期处理可能取决于对他人痛苦的道德关注的个体差异。
Previous studies have shown that intuitive moral cognition occurs at an early stage. However, inconsistent findings indicate that moral information is recognized at a relatively late stage. This study uses the recognition potential (RP) as a neural index and simultaneously measures individuals’ moral preferences using the Moral Foundation Questionnaire. We aim to investigate how individual differences in moral preferences modulate the processing of morality in the pre-semantic stage and provide some insights to explain the variation in rapid information processing linked to morality. The participants performed an implicit task in which recognizable words depicting geographical names or behaviors related to moral, disgusting or neutral content alternated with background stimuli at high rates of presentation. The results showed that the early recognition of moral information manifested in the RP depended on an individual’s moral concerns. Participants with a higher level of endorsement of the harm/care foundation exhibited a greater net moral effect, namely, greater mean amplitudes of the moral-neutral RP difference waves. Meanwhile, only the group that was more sensitive to the harm/care foundation showed a distinctively larger RP for the moral words than for the neutral words. Overall, these findings suggest that the early processing of moral cognition may hinge on individual differences in moral concerns about other people’s suffering.
