摘要：The purpose of this study was to investigate a measuring system that can diagnose an initial dementia. We focused on the relationship between an intial dementia and spatial attention. In this paper, a normal subject's pointing movement to a visual target was measured in three conditions. Condition 1 : Only the target was presented. Condition 2 : Auditory stimulation was added at a location the same distance from the center as that of the target but in the opposite direction. Condition 3 : Auditory stimuation was added at the same location as the target. The results showed that in Condition 3, latency was shorter and the error rate of pointing movements was lower than in the other conditions. These results suggest that, it is possible to measure spatial attention from pointing movements and to control spatial attention by auditory stimulation.
