The purpose of the present study is suggesting the unified theory of metaphor understanding by combining comparison theory (including structure-mapping theory) with class-inclusion theory.
Metaphor's diverse characteristics lead researchers to contrary conclusions on metaphor understanding process in experiments. So, this study demands in advance 1) rating a metaphoric expressions according to four psychological characteristic scales related to metaphor; EASE OF INTERPRETATION, GOODNESS, FELT FAMILARITY, and METAPHORICITY, 2) revealing relationships between them.
The rated items(N = 54) were conventional metaphors or new expressions made by the researcher. Means of ratings in each dimension are presented at Appendix 1. Analysis showed significant correlations between rated dimensions, excepting EASE OF INTERPRETATION and METAPHORICITY(r = .046). These results corresponded to metaphor theories' predictions partially. And, according to metaphor theories metaphor expression is comprehended in different ways. Thus, these demonstrate that metaphors' characteristics are so diverse as to be comprehended through very different cognitive processes.
Then, we divided metaphors into two groups according to EASE OF INTERPRETATION ratings or METAPHORICITY ratings. And, averages of SIMILARITY ratings and NUMBERs of TOPICS was computed for each groups (Appendix 2). Both two groups' SIMILARITY means and NUMBERs of TOPIC were compared each other. Results show that EASE OF INTERPRETATION is related to SIMILARITY(t = 4.783, p < .001) and METAPHORICITY is related to NUMBERs of TOPICs(t = 2.239, p < .05). Results supported comparison theory partially. So did class-inclusion theory. To overcome this problem, it is looked out for how to apply structural-alignment mechanism to creating a suitable attributive category of a vehicle. The proposed unified model of metaphor understanding considers the role of similarity between topic and vehicle, and effects of vehicle typicality in an attributive category.
