摘　　要：本文运用ERP技术,从语境期待和语义整合的角度,探讨不同水平中国学习者加工英语短语动词的神经机制。实验结果显示,高水平学习者仅在加工语义错误且不符合语境的短语动词时才诱发P300和N400成分,而低水平学习者在加工中未发现这两种脑电成分。这表明高水平学习者相关的神经认知机制仍不完善,额外诱发了母语者未出现的P300成分,其原因可能是记忆更新的需要、注意加工的增强以及编码加工的深入;低水平学习者相关的神经认知机制有待建立。同时,高水平学习者诱发了类似母语者的脑电成分,说明二语熟练程度影响学习者加工短语动词的神经机制。With the ERP technique,the present study aims to explore the neural mechanisms of Chinese English learners(CEL)with different English proficiencies in phrasal verbs processing from the aspects of contextual expectation and semantic integration.The experiment results show that the CEL of high proficiency demonstrate P300 and N400 effects only in the processing of semantically and contextually anomalous phrasal verbs.And the CEL of low proficiency show no reliable P300 and N400 effects in the processing of the phrasal verbs.These results prove that the neurocognitive mechanisms of high proficiency CEL are still imperfect with additionally elicited P300,the reasons for which may be memory updating,intensified processing and deepened encoding.And the neurocognitive mechanisms of low proficiency CEL are not yet established.Besides,high proficiency CEL demonstrate more native-like ERP patterns than low proficiency CEL,which indicates the role of language proficiency in the neural mechanisms of L2 processing of phrasal verbs.
