Research Abstract

The purpose of this study is inspection by a system evaluating attention functions using the optic attention. We measured attention, gross motor function, reaction speed in children. And we examined visual attention and relations of reaction speed. As for the subject, the 4-5-year-old children were 19, the 5-6-year-old children were 22. The method tested the visual attention to push the button with the arms in the sitting on the chair. And we tested reaction speed which pushed the button with lower limbs in the standing position. gross motor function measured "side steps", "the standing long jump", "jumping over". We measured center of gravity unrest at the standing position in concentration. We reported a correlation between gross motor function and the attention of 5-6-year-old children before (H23). There was not the significant difference by the comparison of the group where had high motor function group and a low motor function group. Furthermore, the optic attention of the highest children of gross motor function was low, and there was the reverse. Therefore, we thought that the testing of the optic attention at the locus of younger children was not appropriate. However, center of gravity unrest at the standing position and optic attention had a relationship and required attention for standing position posture control for the 4-5-year-old children. Also, as a result of examining gross motor function, optic attention, center of gravity unrest to two 4-5-year-old children with suspected developmental disease, and having compared it with the children of the same age, all values were low. In the case of judging gross motor function and optic attention in the case of 5-6-year-old children from the above generally, 4-5-year-old children, optic attention and gross motor function, the general evaluation that added center of gravity unrest at the standing position more thought that necessary.
