摘要：

目的：采用事件相关电位技术（ERPs）和语义启动范式，探讨道德厌恶启动后对黑白颜色中性词加工的时间特征及其神经机制。方法：采用双字词启动范式，先呈现启动词（道德厌恶词、非道德厌恶词），然后再呈现目标词（黑颜色中性词、白颜色中性词），要求被试对目标词的字形结构作判断。通过探讨不同组合在脑电指标上的差异来探讨其加工特征。结果：与非道德厌恶刺激相比，道德厌恶启动后黑颜色中性词诱发了更大的N1和N350波幅。结论：与非道德厌恶相比，道德厌恶启动后与道德概念的隐喻相关黑白颜色的目标词获得了更多的认知资源，受到了更精细的加工。道德厌恶启动后个体通过更倾向于隐喻道德纯洁的白色，以缓解和释放厌恶感，保持良好的自我道德意象。

Objective: Discussing the time characteristics and neural mechanism of processing black and white neutral words after the activation of moral disgust, by applying event-related potential technique(ERPs) and semantic priming paradigm. Methods: Applied two-character word priming paradigm, which was presenting priming words(moral disgust words, non moral disgust words) first and then target words(black neutrals, white neutrals), and asking the participants to judge the character structure of target words. Processing feature was explored by investigating the differences in EEG indexes of different combinations. Results: Comparing to non moral disgust stimulations, black neutrals triggered greater N1 and N350 amplitudes after activation of moral disgust. Conclusion: Comparing to non moral disgust, after activation of moral disgust, black and white target words related to metaphor of moral concepts obtain more cognitive resources and more refined processing. After activation of moral disgust, individuals tend to relief and release disgust and maintain their favorable moral images by inclining to white, the metaphor of moral purity.
