Abstract

 健常な4~6歳児, 7歳児, 10歳児, 14歳児, 16歳と成人の各群14名ずつ合計84名を対象に, 笑顔図に対する探索眼球運動を評価し, 小児期の対人的な視覚認知機能について比較検討した. 方法は呈示図とともに課題を順に教示し, アイマーク・レコーダにて注視停留点を計測し解析した. その結果, 加齢とともに総移動距離は延長し, 平均移動距離は4~6歳児が他の群より有意に短かった. また, 加齢とともに左スクリーンの停留点数のみが増加した. 笑顔図の8注視エリアである反応探索スコアは加齢とともに増加した. 探索眼球運動は小児期の対人的視覚認知機能の発達を理解する精神生理学的指標として有用と考えられた.

  To evaluate the development of human visual cognitive function in childhood, we examined exploratory eye movements in 78 healthy subjects using affective pictures. We divided them into six groups, each of which comprised 14 subjects (7 boys or men, 7 girls or women) at the indicated ages. Exploratory eye movements were recorded via gazing points using an eye-mark recorder. The total eye scanning length (TESL) of gaze points increased significantly with age, and the mean eye scanning length, in 4-6-year-olds was significantly shorter than in the others groups. The total number of gaze points (TNGP) on the left half of the screen increased significantly with age. The left TNGP in 4-6-year-olds was significantly smaller than in the other groups. The response search score (RSS) measured in 8 areas of the screen increased significantly with age. It was concluded that exploratory eye movements are useful markers to estimate the development of human visual cognitive function in childhood.
