| Research Abstract |
The purpose of this paper is to examine the cognitive mechanism of metaphor comprehension and appreciation through a computational, psychological and linguistic approach, and we obtained the following results :
(1) Metaphor comprehension : Concerning nominal metaphors (of the form "A is B"), we have proposed the interpretive diversity theory which argues that interpretively more diverse metaphors are easier to comprehend via a categorization process, and thus less diverse metaphors fail to be processed as categorizations and reinterpreted as comparisons. We have then shown the superiority of the interpretive diversity theory over the other metaphor theories both psychologically and computationally. For adjective metaphors (e.g., red voice) and predicative metaphors (e.g., The rumor flew through the office), which surprisingly few metaphor studies have addressed, we have proposed a new theory, two-stage categorization theory, which argues that adjective metaphors and predicative metaphor

s are comprehended via a two-stage categorization process. We have shown the superiority of the two-stage categorization theory through the semantic space based computer simulation.
(2) Metaphor appreciation : We have empirically demonstrated that the process of metaphor appreciation, in particular the process of assessing metaphor poeticality can be explained by the mechanism of incongruity resolution and other processes (i.e., semantic processing and aesthetic judgment). For color adjective metaphors, we have revealed through both psychological experiments and corpus analysis that color adjective metaphors tend to evoke negative meanings.
(3) Preference for the metaphor/simile form and the processing differences between metaphor and simile : We have empirically shown that interpretive diversity better explains the preference for the metaphor form. Furthermore, we found that the process of simile appreciation differs from the process of metaphor appreciation ; comprehensible and diverse metaphors are appreciated only through a semantic process, but comprehensible and diverse similes are appreciated through an aesthetic process.
