概念隐喻的心理表征：域映射还是结构相似

概念隐喻在大脑中如何表征？隐喻表征模型认为概念隐喻的目标域不能独立地自我表征，必须借助于始发域的表征，因此目标域和始发域之间是映射关系。结构相似模型认为目标域和始发域各自独立表征，它们构成概念隐喻是因为它们具有结构相似性。本文从论证的有效性，同一域的多隐喻，词的多义等三个方面对两个模型进行了比较和评述，同时提出了需要进一步研究的问题。

The mental representation of conceptual metaphor: domain mappingor structural similarity

The mental representation of conceptual metaphor is a controversial issue. The metaphorical representation model considers that the representation of target domain is the mapping from the source domain. The structure similarity model is in direct contrast to the metaphoric representation model and insists on that the formation of conceptual metaphor is based on the structural similarity of target domain and source domain. This paper evaluates the two models in terms of the validity of evidence, the multiple metaphors in a single domain, polysemic meanings of a word. Meanwhile, it also puts forward the questions for further studies.
