Outline of Final Research Achievements	The aim of this study was to integrate a new perspective of "performance monitoring" as a crucial mechanism of motor learning into rehabilitation science. The error detection capability that supports motor learning was evaluated by recording the error-related negativity (ERN) and the correct-related negativity (CRN) in a spatial Stroop task. It was revealed that both ERN and CRN predicted motor learning processes. Participants who had recovered from anterior cruciate ligament (ACL) injuries exhibited a smaller ERN amplitude than healthy participants, suggesting weaker performance monitoring. In addition, a simultaneous recording of fMRI and ERN showed the importance of evaluating performance monitoring in association with the functional connectivity between the anterior cingulate cortex and the anterior insulae. The paradigm adopted in this study can evaluate ERPs independent of dynamic movements and thus is applicable for any sporting subjects.

Academic Significance and Societal Importance of the Research Achievements	運動学習過程をパフォーマンスモニタリング（PM）から評価できることを示した意義は大きい。また、PMの低い者は受傷リスクが高いことが示唆され、MPの事前評価によって受傷リスクを低減させる可能性を示した。大筋運動と切り離して認知課題でPMを評価する本研究の手法は、あらゆるスポーツ種目に適用可能であり、応用可能性が高いものである。
