项目摘要

The present study was conducted not only to assesses neuropsychologically the concept attainment dysfunction of the patients with different infarcted focuses in the brain, but also to investigated the possibility of using a personal computer as the cognitive rehabilitation tool in order to compensate the concept attainment dysfunction. From the view point to Boston process approach to the cognitive dysfunction, especially, the present study examined the learning performance scores as well as the learning process, which the patients yielded during the concept attainment tasks.The present study revealed the following results ; (1) Using the discrimination shift learning tasks as the neuropsychological assessment tasks, various concept attainment dysfunctions could be dissociated with regard to the unilaterally infarcted hemispheres. Especially the adult patients with left hemispheric infarction took the simple learning strategy of S-R type, which is developmentally low level of learning strategy, in stead of taking the verbally mediated strategy, which other adult patients with the right hemispheric infarction could usually use. (2) It showed that the concept attainment dysfunction is deeply related to the dysfunction of visual object recognition, suggesting the results of identification and working memory dysfunctions in the time-spatial integration tasks, using patients with unilateral hemispheric infarction. (3) The usefulness of the personal computer as a cognitive rehabilitation tool could be showed by means of applying the soft wears to the patients with the concept attainment dysfunction.

本研究不仅从神经心理学的角度评估了不同脑梗死灶患者的概念获得功能障碍，而且还探讨了使用个人电脑作为认知康复工具以补偿概念获得功能障碍的可能性。本研究从认知功能障碍的波士顿过程观点出发，特别考察了患者在概念获得任务中的学习成绩和学习过程。（1）采用辨别转移学习任务作为神经心理评估任务，各种概念获得功能障碍可以与单侧梗死半球分离。特别是成年左半球梗死患者采用了S-R型的简单学习策略，这是一种低水平的学习策略，而不是其他成年右半球梗死患者通常采用的言语中介策略。(2)结果表明，概念获得障碍与视觉物体再认障碍密切相关，提示单侧脑梗死患者在时空整合任务中存在辨认和工作记忆障碍。(3)个人电脑作为一种认知康复工具的有效性可以通过将软穿戴应用于概念获得障碍患者来体现。
