| Research Abstract |
In this study, for human object recognition, it is assumed that we recognize graspable tools such as a drinking cup by making good use of internal models of our own hands (Katayama and Kawato, 1990). In order to validate this hypothesis, we investigated whether the internal models affect object recognition of a tool or not. As a result, we found that the sizes that participants recognized the displayed objects as a drinking cup depended on the trained internal model of the geometrically transformed hand shape. These results indicate that human object recognition of tools such as a drinking cup is closely related to the internal model of the human hand.
