Outline of Final Research Achievements

In combining two concepts as conceptual blending, novel features, which are atypical characteristic of the original concepts, emerge as creative features. Similarly, interpretations of metaphor “topic (A) is vehicle (B)” involve creative features that are not typical characteristics of the words (A and B). In this research, psychological experiments with eye-tracking and a fMRI experiment were conducted to make clear a cognitive mechanism and neural network of the creative interpretations. As a results, it was suggested that the mechanism consists of semantic searching and evaluation for features.
