项目摘要

1. The acquisition processes of perceptual functions on the moving (by feet) and the operating (by hands) behavior were investigated in a congenitally blind person after an operation performed for regaining her sight The subject was born blind due to congenital cataract, and underwent aspiration of both cataract lenses 73 days after birth. The main results obtained during a period of 5 years following surgery were as follows. When she was 4 years dd, she could not stand on his feet without the support of her both hands, and could not see the moving light point on TV display without touching on it with her fingers. During a period of 5 years she gradually attained the ability to see the moving light point, and distinguish colors and shapes and to stand on her feet without helping by her both hands, and to walk. But she stopped in front of the shadow and the stair.2. The acquisition processes perceptual functions of the moving and operating behavior were investigated in a covered vision, a inverted vision, and a restricted vision. The subject (SASAKI) wore the eye-mask, the inverted spectacles, and the pin-hole goggles(visual field:3 degrees) during three days. The main results obtained during a period of 4 years were as follows. The acquisition processes of perceptual functions between the moving behavior in a covered vision and the form perception of subject who had gained sight after surgery were similar in the point of jointing the exploring points about the object outline and between the walking behavior in a inverted vision and the solid form grasping of the subject who had gained sight after surgery were similar in the point of integrating the information of exploring points about object outline gaining from of the point of view.

1.本文研究了一名先天性失明患者复明手术后的运动（用脚）和操作（用手）知觉功能的获得过程。受试者因先天性白内障而先天失明，出生后73天接受了双侧白内障晶状体摘除术。手术后5年期间获得的主要结果如下。当她4岁的时候，如果没有双手的支撑，她就不能站在他的脚上，如果不用手指触摸，她就不能看到电视显示屏上移动的光点。在5年的时间里，她逐渐获得了看到移动光点的能力，并区分颜色和形状，并在没有双手帮助的情况下站立，并行走。但她在阴影和楼梯前停了下来。在遮盖视觉、倒置视觉和限制视觉条件下，研究了运动和操作行为知觉功能的获得过程。受试者（SASAKI）在3天内佩戴眼罩、倒置眼镜和针孔护目镜（视野：3度）。在四年期间取得的主要成果如下。手术后复明者在遮盖视觉中的运动行为与形状知觉知觉的知觉功能获得过程在对物体轮廓的探索点的联结点上是相似的，手术后复明者在倒置视觉中的行走行为与立体形状抓握的知觉功能获得过程在对探索信息的整合点上是相似的关于物体轮廓的观点。
