Outline of Final Research Achievements

Even in crowded places, we can reach our destination without disrupting others' way. This ability to coordinate with others can be termed "Physio-sociality". We therefore investigate developmental changes in this ability using the triadic jumping task (Kijima et al., 2017). Three children from 2nd, 4th, and 6th grades, with varied personality traits were asked to perform triadic jumps. Each of the 10 triads included a "leader," a "follower," and an "intermediate" child in the context of daily classroom activities. Analysis of the action coordination revealed: (1) the "leaders" tended to lead the other two whenever the environmental geometry forced them to follow others, (2) the effect of their leadership trait never exceeded that of the geometry, and (3) the "leadership" effects and geometrical constraints gradually reduced as the school grade advanced. These findings constitute the cornerstone for the development of "Physio-sociality" for people with Asperger’s syndrome.

Academic Significance and Societal Importance of the Research Achievements

与えられた場に様々な個性が集まり，各自が自他の立ち位置を理解しながら共通の目的に向かって協力する．我々はこの基盤をなす知性を身体的社会性と呼び，その育成を体育の課題と考える.
従来から社会性の数理を検討した例はあるが（e.g. Strogatz, 1988），これらはモデルの挙動を計算機で検証するにとどまり，実社会における人間のふるまいとの対応を検討していない．本研究では環境の物理構造と人間の意思決定が身体行為を介して結びつく構造を解明した．その秩序を象る代数の規則は従来の理論研究に生態学的な妥当性を付与する．さらに本研究が解明した秩序の発達変化は身体的社会性の教育基盤をもたらすはずである．
