中文摘要：

本研究采用ERP实验,以被试的反应时间、错误率和脑电成分N400为参考因素,探索高级双语者在加工第一语言时是否自动检索第二语言。结果显示,内隐的英语首发音条件引起的效应没有体现在反应时间上。在ERP实验结果中,被试在判断语义相关的词语时,大脑语言区域的N400在词语英译首发音一致与否的情况下差异不显著;而判断语义无关的词语时,N400在该条件下显著。实验结果分析表明,高级双语者在深度加工第一语言时,大脑可能无意识地检索第二语言。

英文摘要：

Adopting Event Related Potential,measuring the reaction time,error rate and N400,this paper investigates whether the advanced Chinese-English bilinguals retrieve the second language when they are processing their mother language.The results reveal that the implicit conditions,the first English pronunciation did not reflect on the reaction time.In the ERP result,while bilinguals are confronted with semantic related judgments,N400 invoked by the language areas fails a significant difference from the implicit first English pronunciation.However,when faced with the semantic unrelated judgments,N400 shows significant difference between each implicit first English pronunciation conditions.It is concluded that when advanced bilinguals are making comparatively complex and semantic judgments,the second language can be unconsciously retrieved.
