人类语言在大脑的运作机制是语言学、认知科学、神经科学和脑科学长期共同关注的重要课题,单机制理论和双机制理论都对此做出了假设和解释。本文首先简要介绍单机制理论和双机制理论,然后从第一语言、第二语言、神经语言学和自然语言四个角度阐释了双机制理论在解释语言大脑运作机制时较单机制理论所具有的优越性。文章最后挖掘双机制理论对于外语词汇教学的启示。
The working mechanism of human language in the brain is an important topic that has long been a common focus of linguistics, cognitive science, neuroscience and brain science. Both the theory of single mechanism and the theory of dual mechanism make assumptions and explanations. This paper first briefly introduces the single-mechanism theory and the double-mechanism theory. Then from two perspectives: first language, second language, neurolinguistics and natural language, this paper illustrates that dual-mechanism theory has more advantages than single-mechanism theory in explaining the mechanism of linguistic brain Superiority. Finally, the paper explores the implications of dual mechanism theory for foreign language vocabulary teaching.
