以快速序列视觉呈现法呈现汉字,采用事件相关电位技术探讨在汉字加工过程中重复知盲效应的认知神经机制.结果发现:在200~300 ms内,产生RB效应的序列刺激比重复判断正确的序列刺激有一个更负向的偏移;而在600~800 ms内,产生RB效应的序列刺激比非重复判断正确的序列刺激有一个更负向的偏移.表明RB效应可能是由于重复的汉字R2在早期知觉阶段不完整的加工而导致其在工作记忆中受到抑制而产生的.
Chinese characters were presented by fast sequence visual presentation method and the cognitive neural mechanism of repetitive blindness in Chinese character processing was explored by using event-related potential technique.The results showed that within 200-300 ms, sequence stimulation with RB effect was more accurate than repeat Had a more negative bias in sequence stimuli, while the sequence stimulus with RB effect produced a more negative bias than the sequence stimulus with non-repetitive judgments within 600-800 ms, indicating that the RB effect may be due to repetition Of the Chinese character R2 in the early stages of perception incomplete processing led to its inhibition in working memory arising.
