Outline of Final Research Achievements

The brain learns a prior distribution of sensorimotor tasks to generate Bayesian estimation, which improves the task precision. In our daily tasks such as sports, the brain should learn multiple prior distributions. Based on “motor specificity (Roach et al. & Heron. 2017),” we conducted psychophysical experiments. As one of main research outcomes, we found “motor-effector specificity.”  When the short and long priors (i.e., fastballs/slowballs) were assigned to different motor effectors, participants concurrently learned the two independent priors. Moreover, the two priors were learned faster when the priors were assigned to anatomically distant body parts. These psychophysical findings also provided an effective hypothesis for the neural basis of learning of multiple prior distributions.

Academic Significance and Societal Importance of the Research Achievements

タイミング/時間知覚におけるベイズ推定は,国際的な重要研究課題の一つとなった.スポーツのような日常の課題でベイズ推定が有効に機能するためには「複数の事前分布の学び分け」が必要である.本研究は,上述の運動効果器特異性をはじめ,「複数の事前分布の学び分け」を可能とする条件を複数明らかにした.これらの成果は,有力な神経基盤の候補を矛盾なく示し,さらにスポーツ技能の向上法の提案やスポーツ選手の技能メカニズムの解析をするための基盤知見となることが期待される.
