基于ERP实验的二语句子阅读能力的心理现实性研究

An ERPs Study on the Psychological Reality of Sentence Comprehension Competence in the Second Language

文章通过ERP技术研究二语习得过程中句子阅读能力的心理现实性问题,通过实验以及对P2、N400、LPC等成分的讨论可以看出,在阅读时,L2学习者的阅读能力表现在单词识别上,识别程度低于L1单词;在阅读理解上,相比较于L1句子的理解,L2学习者可能会更多地把脑资源放在单个词的理解上,而没有(也不能)像阅读L1句子时,把更多的脑资源放在对整个句子的整合理解上,因而,整合理解的水平明显低于L1句子。通过P2、N400、LPC等成分我们可以很好地观察到阅读能力在大脑中的表现,阅读能力具有显著的心理现实性。

This paper examines the psychological reality of reading ability during the second language acquisition using event- related brain potentials(ERPs).The discussion of P2,N400 and LPC shows that the reading ability of L2 learners focuses on word recognition during reading,however,the extent is less than L1 word recognition;as to the reading comprehension,L1 learners focus more brain resources on word comprehension than L1 sentence comprehension,and when they read L1 sentences,they focus more brain resources on the integration of the entire sentence understanding.Therefore,their integration of understanding is obviously not as good as L1 sentence understanding.We can investigate reading ability in the brain vividly through P2,N400 and LPC.Reading ability has a significant psychological reality.
