| Abstract(in English) | There is little evidence that how visual and proprioceptive representations of hands are integrated into a visuo-spatial map for action. In this study, we investigated the effect of visual representation of hands in a spatial S-R compatibility task. Participant: A 32-year-old man (GY) with left parietal lobe damage participated. As a result, when a patient responded by opposite keys to the target location, reaction time of crossed-hand condition under uncovered hands was longer than any other visual conditions. Error rate was highest in that condition under fake hands among other visual conditions. Results suggested that the longer RT under uncovered hands reflected GY's deficit in matching of visual representations of hand to proprioceptive one, while error responses under fake hands reflected failure of matching these representations. It was difficult for GY to remap and match multiple representations of hands. These processes might involve coding a visuo-spatial map for action. |
