| Research Abstract |
We investigated the underlying mechanism of the asymmetric confusability effects (ACE) of animate objects. First, we indicated that the findings of previous studies about ACE were confound with methodological problem and proposed the alternative method for the research of the ACE. Second, we examined whether ACE was generalized to the array of face photographs, and furthermore to investigate how the impression of faces affected the ACE. We found that the addition change was easier to recognize than deletion, only related with uniqueness of changed face. Third, we investigated the ACE of children, using the photographs of animate objects(butterflies and cats). The results indicated that the ACE was observed, depending on the type of animate objects, which was in accord with our previous finding using adult subjects. Fourth, we examined the ACE in recognition of scene in everyday life (e.g. park, platform, and school-room). We found that the ACE in recognition of change was mediated by the impression, especially "the feeling of something strange" aroused by addition change. Finally, the related phenomena with the ACE in the other fields were discussed.
