| Outline of Final Research Achievements |
In this study, we measured the movement of the gaze, pursuit, and switching tasks using a gaze measuring device (Gazefinder), and verified the visual task and visual function that can discriminate developmental coordination disorder (DCD). Gazes of 380 participants in the five-year-old checkup were measured by Gazefinder. We create a new video from the analysis results, and the preliminary analysis of 69 5-year-old children was performed on eye movement, which is one of the internal model disorders. In the video of the target moving from bottom to top at low speed and high speed in the pursuit task, the time to visual recognition was significantly negatively correlated with the score of the motor test MABC-2 (p <0.05). In addition, this phenomenon was more remarkable under high speed conditions than under low speed conditions (p <0.05). The final analysis is underway.

| Academic Significance and Societal Importance of the Research Achievements |
世界的に幼児における発達性協調運動障害（DCD）を医学的根拠に基づいて診断している研究は少なく、さらに注視点測定を用いて視機能を測定することにより、DCDの病態解明に寄与するのみならず、客観的評価を用いたDCDの早期発見および早期介入への足掛かりとなる。本研究により、DCDの病態解明に寄与するのみならず、総務省の勧告通り、客観的評価を用いたDCDの早期発見および早期介入への足掛かりとなり、学習障害や二次的な精神障害の予防が実現できると考える。
