Outline of Final Research Achievements

Controlling the motion of the human body precisely requires significant training over a long period of time. Professional musicians have to find the optimal information processing strategy for themselves to excel above all other musicians. In this study, we verified differences in sensory-motor information processing between better ear-players and better sight-readers via administering a questionnaire and conducting behavioral experiments with professional pianists.
The results suggested that both type of pianists immediately transform input information into the information of modality that the easier to memorize for the individuals.

Academic Significance and Societal Importance of the Research Achievements

既存の研究においては，演奏家と非演奏家というくくりで研究が行われており，演奏家内の情報処理方略の差は検証の対象になっていない．同じ出力が得られる場合にはおおよそ同じ方略を使用しているとされてきたため，実際には存在する違いが埋もれたままである可能性がある．その違いを明らかにすることにより，将来的に演奏学習の際の適切な練習方法の提案等に活用することができる．
