作業療法教育課程と観察場面における視覚情報処理機能との関係性—学年間における探索眼球運動の検討より

The relationship between visual information processing of client observations and an occupational therapy course : A comparison of exploratory eye movements at various stages of training

要旨：視覚情報処理機能を反映する探索眼球運動の観察場面における作業療法学科学生の変化と特徴を検討した．この目的は当校における作業療法教育の学年進行に伴う視覚情報処理機能の変化を検討することである．解析は平均注視停留時間，平均移動距離，注視点総数，観察目標である顔及び手元の部位別注視点総数比率とした．その結果，1年生は他学年よりも平均注視停留時間は短く，平均移動距離は長かった．注視点総数は学年の進行に伴い増加した．部位別注視点総数比率は，4年生は他学年よりも高かった．以上のことから学生の探索眼球運動は教育課程の進行に応じて変化し，観察場面における視覚情報処理機能の向上がOTRに近づくことが確認された．

　Exploratory eye movements when observing occupational therapy clients were investigated in order to evaluate visual information processing function in students of four-year occupational therapy programs. This study evaluated educational effects through observing changes in visual information processing function as students advanced through the curriculum. We analyzed mean gaze time (MGT), mean eye scanning length (MESL), total number of gaze points (TNGP) and the ratio of TNGP in the target area using an eye mark recorder. As a result, the MGT and MESL in first-year students were shorter and longer respectively than that of more advanced students. The TNGP increased as the students moved through the four-year program. The ratio of TNGP in fourth-year students was higher than that of other students. These findings suggest that exploratory eye movements change as the students advance through the educational curriculum for occupational therapy observation.
