Outline of Final Research Achievements

We systematically investigated the effects of attentional dispersion during unilateral arm abduction on sensory-motor processing of anticipatory postural control in the elderly. To perform this task, the elderly persons would concentrate on the early response to the target, and pay a lot of attention to sensory processing of the imperative stimulus even in attentional dispersion condition. Therefore, the attentional allocation on the following higher processing, such as the discrimination or motor preparation would be insufficient by attentional dispersion. These changes of the sensory-motor processing by attentional dispersion may relate to the delay of onset time of postural muscles.
