摘　　要：双语者大脑中存在母语和第二语言两个心理词典,第二语言的词汇通达是双语研究的热点.实验使用大脑事件相关电位技术,基于语音判断任务考察中日双语者日文词汇语音通达的时间进程及大脑机制.实验材料为以与中文词的关系而定义的3类不同日文词:同形同义词、同形异词义和非中文词.结果表明:在被试通达日文3种不同词型的语音时,在大脑的额叶存在200ms出现的词形竞争和400ms出现的词义竞争.这种竞争反映了大脑额叶在日文词汇通达中的重要作用.Mother tongue and second language are two mental lexicons in the cerebra of bilinguals. The lexical access of the second language is the focus of bilingual research. A Phonological decision task was used to explore the time course and brain mechanism of lexical access by Chinese-Japanese bilinguals. Brain-event-related potential technique with high temporal resolution was used to observe the brain activity. The result showed that when accessing the Japanese-Chinese same meaning homographic words, different meaning homographic words, and non-Chinese words, there were orthograhic competition at 200 ms and semantic competition at 400 ms in the frontal lobe. A lexicat access model based on activation and competition was Proposed for Japanese word Processing as second language. This competition suggested that the importance of frontal lobe in Japanese lexical access.
