Outline of Final Research Achievements

We developed the "Children's Motor Development Navigator System," which enables quantitative analysis and visualization of children's motor function and motor learning ability based on the evaluation of outputs from predictive and feedback (FB) controllers.
By using this system, we evaluated the change in motor function with aging from children from 6 years old to elementary school students. The results confirm that the early elementary school years are a period of positional control development and the upper elementary school years a period of velocity control development. Overall, this study presents a methodology that allows experimental testing of the role of the cerebellum in children's motor development based on feedback error learning theory (Kawato and Gomi 1992).

Academic Significance and Societal Importance of the Research Achievements

人間の運動制御メカニズムにおいて「人間の運動は予測制御とフィードバック制御によって行われるし、運動学習によってこの２つの運動制御器の精度や割合が変わって行く」というフィードバック誤差学習理論（Kawato and Gomi 1992）がある。本研究では、「フィードバック誤差学習理論が子供の感覚運動機能の発達や発達障害によってどのように成立されるのか」を本研究を通してこの学習理論の成立過程も実験的に検証できることに学術的意義や社会的意義がある。
