认知观认为,通感是一种特殊的隐喻,其源域和目标域都是人们的体验和感知。通感不能简单的理解为语言系统中的词义特征,它不仅是一种修辞手段,更是一种认知方式。传统的通感研究一直拘泥于修辞格的研究范畴,没有把通感上升至认知的高度。人们常用熟悉的味觉范畴词“酸、甜、苦、辣”等隐喻抽象概念或其它概念域。鉴于此,本文旨在收集和归纳英汉中“酸”对应的通感隐喻,并探索通感隐喻在英汉语中的认知模式,挖掘“酸”味觉概念隐喻的投射存在的普遍性和差异性,以期探寻通感隐喻所蕴含的人类心智的体验性和哲学意义。 Cognitive view that synesthesia is a special metaphor, the source and target domains are people’s experience and perception. Synaesthesia can not simply be understood as the meaning of words in the language system, it is not only a rhetorical device, but also a cognitive approach. The traditional research of synaesthesia has been rigidly adhered to the category of rhetorical research, without raising synaesthesia to the level of cognition. People often use the familiar taste category “metaphorical” such as “sour, sweet, bitter, spicy” or other conceptual domains. In view of this, the purpose of this paper is to collect and summarize the synaesthetic metaphors corresponding to “acid ” in English and Chinese, to explore the cognitive modes of synaesthetic metaphors in English and Chinese, Sexuality and difference, with a view to exploring the experience and philosophical significance of the human mind contained in the metaphor of synaesthesia.
