摘　　要：本研究利用ERP技术研究了英汉心理词典中英语二语单词的再认模式.脑电数据分析表明对高熟悉度英语单词的再认在300～500ms内产生了基于熟悉度的顶区事件记忆效应,对低熟悉度英语单词的再认随着时间的变化从顶区向额区扩展,即先进行300～ 500ms顶区的基于熟悉度的再认,再进行500～700ms额区的基于回想的再认.因此,我们认为中国英语学习者对高熟悉度英语单词的再认为独立模式：直接进行基于熟悉度的顶区再认;对低熟悉度单词的再认是连续体模式：先进行基于熟悉度的顶区再认,再进行基于回想的额区再认.According to dual process models, successful recognition memory performance reflects two different neurocognitive processes: familiarity-based and recollection-based. The present paper investigates the recognition of English words in English-Chinese mental lexicon by means of ERP technology. ERP analyses indicate that the recognition of high familiarity English words shows the parietal episodic memory effects during 300 ~ 500 ms based on familiarity,and the initial recognition of low familiarity English words shares the process with high familiarity English words,but with an extension to the frontal episodic memory effects during 500 ~ 700 ms based on recollection.Therefore,we conclude that the recognition of high familiarity English words in English-Chinese mental lexicon employs an independent process,which means a direct recognition of the target words during 300 ~ 500 ms based on familiarity in parietal area,while the recognition of low familiarity English words is a continuous dual process,which means a first recognition of the target words during 300 ~ 500 ms based on familiarity in parietal area,followed by a subsequent recognition during 500 ~ 700 ms based on recollection in frontal area,and that familiarity-based recognition in parietal area and recollection-based recognition in frontal area are two phases of the word recognition of English as a second language in English-Chinese mental lexicon and they occur in an orderly sequence.
