| Outline of Final Research Achievements |
We analyzed the responses of subjects (healthy young, healthy elderly, and patients with dementia) to the lexical decision tasks and feature-listing tasks. In the lexical decision tasks, the reaction times of the patients in the dementia group were significantly longer than those of the subjects in other groups. Furthermore, patients in the dementia group displayed evident individual differences. In the feature-listing tasks, the number of words produced by the patients in the dementia group was significantly fewer than that produced by the subjects in the other groups. The ratios of introspective words produced by the subjects in dementia and elderly groups were significantly greater than that produced by the subjects in the young group. It was remarkable in the dementia group. These results suggest that lexical-semantic processing degenerates because of aging and dementia. We obtained an effective result regarding communication support for patients with dementia.
