第二语言学习的认知神经机制

The Cognitive and Neural Mechanisms of Second Language Learning

第二语言学习的认知神经机制是语言心理学研究的一个前沿课题。对第二语言学习的认知神经机制研究进行梳理和分析,总结发现:(1)第二语言学习者主要使用母语的神经网络学习和加工第二语言;(2)使用母语加工神经网络越多的学习者,第二语言学习成绩越好;(3)第二语言是在母语和第二语言不断交互作用中习得的。未来研究需要借助f MRI、ERP、t DCS等现代认知神经科学技术,在自然语言环境和实验室语言学习环境下,综合使用单变量和多变量数据分析方法,系统探讨第二语言学习的认知神经机制,并在此基础上探寻促进第二语言学习的有效方法和途径。

The cognitive and neural mechanisms of second language learning are one of the most important questions in the area of psycholinguistics.This paper reviewed the literature on cognitive and neural mechanisms of second language learning,and found that(1)second language learners recruits neural networks of the native language to learn and process the second language;(2)greater engagement of the native language network during learning benefits second language learning;and(3)the second language is acquired by interacting with the native language.Future studies should adopt fM RI,ERP,and tD CS technologies to systematically examine the cognitive and neural mechanisms of second language learning by using both univariate and multivariate analyses in the circumstances of natural language learning and language learning in the laboratory and to identify the effective ways to facilitate second language learning.
