Black and white have been shown to be representations of moral concepts. The purpose of this study was to investigate whether colours other than black and white have similar effects on words related to morality and to determine the time course of these effects. We presented moral and immoral words in three colours (red, green and blue) in a Moral Stroop task and used the event-related potential (ERP) technique to identify the temporal dynamics of the impact of colours on moral judgement. The behavioural results showed that it took longer for people to judge immoral words than moral words when the words were coloured green than when they were red or blue. The ERP results revealed the time course of these effects. Three stages were identified in the significant effects of P200, N300 and LPC. These findings suggest a metaphorical association between the colour green and moral information.
黑与白被证明是道德概念的代表。本研究的目的是调查除了黑与白之外的其他颜色是否对与道德有关的单词有类似的影响，并确定这些影响的时间进程。我们在一项道德斯特鲁普任务中呈现了三种颜色（红、绿和蓝）的道德和不道德的单词，并使用事件相关电位（ERP）技术来识别颜色对道德判断的影响的时间动态。行为结果表明，当单词为绿色时，人们判断不道德单词比判断道德单词需要更长的时间，而当单词为红色或蓝色时则不需要。ERP 结果揭示了这些影响的时间进程。在 P200、N300 和 LPC 的显著影响中确定了三个阶段。这些发现表明绿色与道德信息之间存在隐喻性关联。
