| Outline of Final Research Achievements |
The present study aimed to reveal the underlying mechanism how bodily movements influence cognitive processing of written language by using young and elderly healthy individuals and brain damaged patients. The series of experiments consistently showed that kusho behavior positively affected cognitive task performance (Kanji construction task) only when the visual feedback of the finger movements was available. In addition, we showed a positive correlation between the task performance and vocabulary score only in the condition that target stimuli were presented for 3 seconds. Further, we confirmed that the facilitation effects of kusho behavior for the elderly individuals and a patient with a parietal lobe lesion. These results together supported the hypothesis that the visual aspects of kusho behavior assist cognitive processing regardless of the general cognitive ability.
