STUDY FOR THE NEUROPSYCH0LOGICAL ASSESSMENT AND COGNITIVE REHABILITATION OF THE CONCEPT ATTAINMENT DYSFUNCTION

本研究不仅对不同脑梗死灶患者的概念实现功能障碍进行神经心理学评估，而且探讨了使用个人电脑作为认知康复工具来补偿概念实现功能障碍的可能性。从认知功能障碍的波士顿过程方法的角度出发，本研究考察了患者在概念获得任务中产生的学习表现分数和学习过程。本研究揭示了以下结果：(1)将辨别移位学习任务作为神经心理评估任务，可以分离单侧脑梗死的各种概念获得障碍。尤其是成年左脑梗死患者采用的是发育水平较低的S-R型简单学习策略，而非其他成年右半脑梗死患者通常采用的言语介导学习策略。(2)单侧脑梗死患者的概念获得障碍与视觉物体识别障碍有密切关系，提示其在时空整合任务中存在识别和工作记忆障碍。(3)通过对概念获得障碍患者进行软性穿戴，可以显示个人电脑作为认知康复工具的实用性。

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.
