【摘要】：双语者经常需要从所掌握的一种语言转换到另一种语言,这种现象被称为语言转换。伴随认知神经科学技术的发展,研究者除了系统地探讨双语语言转换的认知机制外,对双语语言转换的神经机制也进行了一定的探讨。语言转换是一种复杂并且高级的认知活动,需要依赖基本的认知能力,如认知控制。基于此,研究者首先探讨了双语语言转换与一般认知控制在神经机制上的差异。语言加工一般包括语言理解和语言产生两个过程,研究者重点对语言理解和语言产生中双语语言转换的神经机制进行了探讨。语言转换作为第二语言学习过程中普遍存在的一种语言现象,研究者还从大脑可塑性的角度探讨了语言转换经验对大脑的结构和功能产生的影响。未来的双语语言转换研究还要注意结合多种方法、使用更丰富的认知神经科学技术探讨语言转换的神经机制,另外,还要注意结合多门应用学科拓宽语言转换神经机制研究的应用价值,把研究成果更好地应用于第二语言学习与教学。
[Abstract]:Bilinguals often need to switch from one language to another, a phenomenon known as language conversion. With the development of cognitive neuroscience and technology, researchers have systematically explored the cognitive mechanism of bilingual language conversion. The neural mechanism of bilingual language conversion is also discussed. Language conversion is a complex and advanced cognitive activity that relies on basic cognitive abilities, such as cognitive control. The researchers first explored the differences in neural mechanisms between bilingual language conversion and general cognitive control. Language processing generally involves two processes: language understanding and language generation. The researchers focus on the neural mechanism of bilingual language conversion in language understanding and language production, which is a common language phenomenon in the process of second language learning. The researchers also explored the effects of language conversion experience on the structure and function of the brain from the perspective of brain plasticity. The use of richer cognitive neuroscience techniques to explore the neural mechanisms of language conversion, in addition to the need to combine multiple applied disciplines to broaden the applied value of the study of the neural mechanism of language conversion, To better apply the research results to second language learning and teaching.
