中文摘要：

采用＂学习-测验＂范式,在知觉辨认测验（内隐测验）和再认测验（外显测验）中,用事件相关电位探索汉字内隐、外显记忆的＂知觉干扰效应＂。结果：行为上,内隐记忆不受知觉干扰条件的影响;外显记忆受知觉干扰条件影响而显著降低;脑电上,内隐测验两种条件的ERP无显著差异;外显测验在550～600ms,知觉干扰条件比无干扰条件诱发了更负的ERP。实验在行为和脑电水平上都表现出内隐、外显记忆的分离,出现汉字的＂反知觉干扰效应＂。

英文摘要：

Using a＂study-test＂paradigm,the present experiment investigated the perceptual interference effect of memory in Chinese characters with ERPs.Explicit and implicit memory was measured with recognition tests and perceptual identification tests respectively.Recognition performance was better in the intact condition than in the interference condition.In implicit memory tests the perceptual identification performance made no difference between the intact and interference conditions.In 550～600-ms windows,the ERP during a recognition test was more negatively deflected in the interference condition than the intact condition, which indicated a better recognition memory in the former than the latter condition.By contrast,in terms of ERPs during a perceptual identification test,the difference between the two encoding conditions was not significant.Both the behavioral and the ERP data indicated a dissociation between explicit and implicit memory and indicated an inverted perceptual interference effect in the explicit memory of Chinese characters.
