说话者为了达到自己的交际目的而选用语码转换来实现对语言现实、社会规约及心理动机的顺应,从而最终实现自己的交际意图。本文从认知语言学的角度来研究语码转换,运用顺应论,结合具体语料对语码转换进行解释,由此阐明语码转换的认知基础、认知途径及认知心理过程,从而揭示语码转换的认知心理机制,并在此基础上构建其认知心理模型图。 In order to achieve their own communicative purposes, the speaker chooses code-switching to achieve compliance with language reality, social norms and psychological motivation, so as to finally achieve his own communicative intention. This article studies the code-switching from the perspective of cognitive linguistics, and uses the theory of adaptation to interpret the code-switching with concrete corpus, so as to clarify the cognitive basis, cognitive pathway and cognitive psychology of code-switching, Code-switching cognitive psychology mechanism, and on this basis to build its cognitive psychology model map.
