摘　　要：本研究采用经典的句尾畸义词诱发N400的ERP实验范式探讨了中国英语学习者在进行英文阅读时语音的影响及其相关脑机制。实验包括两类畸义语句:1.同音畸义:句尾词有畸义,但语音和相应正常语义句尾词相同;2.非同音畸义:句尾词有畸义,且语音和相应正常语义句尾词不同。行为数据显示:在错误率上同音畸义显著地高于非同音畸义。ERP显示:无论在早期(N100)还是晚期(N400)脑电成份上,同音畸义和非同音畸义的ERP振幅都有明显差异。本研究从行为和脑电两个方面一致揭示中国英语学习者阅读英文时受到了语音的影响。Using the ERP paradigm of end-of-sentence semantic anomalous word elicited N400, the present study investigated the effect of phonological information on Chinese second language learners of English while reading English sentences and its brain mechanisms There were two kinds of semantic violated sentences： 1. semantic anomalous en＆of-sentenee word which was a homophone of the expected word; 2. semantic anomalous end-of-sentenee word which was nor a homophone of the expected word. The behavior data showed a significantly high error rate of the homophone semantic anomalous condition compared with the non- homophone semantic anomalous condition. The ERPs reveals a significant difference between the homophone semantic anomalous condition andthe non- homophone semantic anomalous condition on both early ERP component N100 and late component N400. The behavioral and eleetrophysiologieal results consistently revealed that Chinese second language learners of English were affected by the phonological information while reading English sentences.
