与其他语言单位一样,语篇具有模糊性,但语篇不像其他语言单位那样由外部形态上的一个或一个以上的次级单位所构成;语篇的模糊性还在于语篇与语境的关系,以及不同的主体对它们之间关系的认知的极差性,因此对语篇的生成与理解过程开展认知分析更有助于我们认识它的模糊性。本研究运用概念整合理论分析范畴的本质,解读语言范畴化模糊性的认知理据;结合心理空间理论分析人脑在语篇的生成与理解过程中的认知活动,探究语篇模糊性的认知原理。 Like other language units, the discourse is ambiguous, but the discourse is not composed of one or more sub-units in the external form like other language units. The ambiguity of the discourse lies in the discourse and context Relationship, and different subjects have very poor understanding of the relationship between them. Therefore, cognitive analysis of the process of text generation and understanding helps us to understand its ambiguity. In this study, we use conceptual integration theory to analyze the nature of categories and interpret the cognitive motivation of linguistic categorization ambiguity. Combining with the theory of psychological space, we analyze the cognitive activity of the human brain in the process of generating and understanding texts, Know the principle.
