摘要
采用事件相关电位技术和语义启动范式,考察身体清洁刺激启动后对道德纯洁词加工的影响及其内在神经机制,探讨身体清洁信息与道德纯洁信息的认知加工特征。研究通过启动词(清洁词VS非清洁词)与目标词(道德纯洁词VS非词)四类刺激类型在N400波幅和潜伏期上有无差异来进行判断。结果发现,启动词(清洁词VS非清洁词)与目标词(道德纯洁词VS非词)四类刺激类型所诱发的N400成分差异显著,与非清洁词-道德纯洁词相比,清洁词-道德纯洁词所诱发了更小的N400波幅。结果表明:身体清洁词与道德纯洁词之间存在紧密的语义联结。身体清洁词启动后,个体更关注道德纯洁信息。
The present study adopted the event-related potential technology and semantic priming paradigm to explore the neural mechanisms and the characteristics between physical cleaning and moral purifying. The research attempted to identify the feeling of moral purity after physical cleaning priming through four types of stimuli, priming words （physical cleaning words VS non physical cleaning words） and the target words （moral purifying words VS non- words）. The difference of N1, N400 component was regarded as index to determine internal relations between physical cleaning and moral purifying. The N400 amplitude showed significant interactions of the priming words x the target words. The N400 amplitude of physical cleaning words was lesser to non-physical cleaning words when the moral-purify words as target words. The results indicated that there are strong relations between physical clean- ing and moral purify. The sense of moral purifying would be strengthened after physical cleaning.
