| Outline of Final Research Achievements |
Although people cannot maintain eye-tracking velocity when a moving target is invisible, people may correct for the position error (the distance between the eye gaze and the moving target) by saccades that bring the eye gaze towards the target trajectory. In the present research, we focused on the Electroencephalogram (EEG) power spectrum involved in the correction of this position error. The results showed that the position error decreased as EEG power increased in the right posterior temporal region related to the tracking of a moving target after the target occluded. Our findings suggest that the activity of the right posterior temporal region is involved in reducing position errors when a moving target is invisible.

本研究成果の学術的意義は，これまで明らかにされていない滑動性追跡眼球運動，サッケードの眼球運動ストラテジーによって，いかにターゲットに対する視線のポジションエラーを減らしているかを，その時の脳内の活動様式と対応させて明らかにした点です。本研究成果の社会的意義は，移動するターゲットをどのような思考の下で見るべきか，「視線ストラテジー」を提示することで，円滑な球技スポーツの教育や指導が期待できるが，本研究で得られた成果はその資料の一部になり得ると考えられます。
