A Study on Some Mechanisms in Improvement of Visual Cognitive Function on the B asis of Psychological, Educational and Technological Approach.

当我们试图改善有各种障碍的人的视觉认知功能时，我们需要一系列的知识，但到目前为止，我们还没有获得这些知识的心理和/或教育研究。为了弄清视觉认知功能的发展过程，我们必须探讨以下几个问题：1）视觉空间的稳定性; 2）视野的作用; 3）视觉对人类行为的引导和控制。在本研究中，我们邀请了一些视力障碍者作为研究对象进行合作，并获得了他们的同意。研究对象包括脑损伤、先天性白内障、智力低下和部分视力的人。本文首先分析了他们的残疾状况，并在此基础上进行了改善他们视觉认知功能的研究。本研究结果揭示了物体在空间中的定位和物体的识别是在不同的基本机制基础上分别获得和进行的，以及在日常生活情境等视觉功能获得过程中动觉功能的重要性，这些发现有望应用于教育、心理学和工程学为残疾人服务。

We need a series of knowledge when we try to improve the visual cognitive function of the people who have various impairments, but we do not have the psychological and/or educational researches available for acquiring those knowledge so far. We have to investigate the following problems in order to make clear the developmental process of the visual cognitive function : 1) the stability of the visual space, 2) the role of the visual field, 3) vision ot guide and control human behavior. Moreover we emphasize the importance to investigate these problems in the daily living situation as far as possible.In this study, we asked some people with visual impairment to co-work as subjects for the research and could obtained their consents. The subjects contained people with brain damage, congenital cataract, mental retardation and partial sight. In the first place we analyzed the state of their disabilities, and on the basis of the data we were engaged on a research to find the methods of improving their visual cognitive function. The results of this study revealed that the localization of the object in the space and the identification of it were acquired separately and carried out on the basis of the different basic mechanism, and that the kinesthetic function was very importance in the process of acquiring visual function in the daily living situation and so on. These findings are expected to be used in the various field of science such as education, psychology and engineering for the handicapped.
