大脑半球损害与木块图案测验

<正> 大脑两半球各有不同的优势,左侧大脑半球的语词性优势,早巳为大家所熟悉,割裂脑病人的研究更证明右侧大脑半球对进行非语词的、空间的信息具有特殊的作用。Johnstone(1979)的研究发现当说话或进行木块图案操作时在脑电图描记上R/L比

The Block Design Tasks In Cerebral Hemispheric Lesion

Twenty five patients with hemispheric lesion, ten patients without hemispheric lesion and eleven normal subjects were each tested on twelve items from Goldstein-Seheerer's and six items from Kohs block design series. Each subject used only one hand for each design, alternating hands Throughout the series. To avoid further bias caused by differences in difficulty between paired items,the order of Persentation was counterbalanced between subjects. Standard scoring was used and analyzed for each subjects left and right hand.The primary result of this study shows. (1) the performance of the right handed normal subjects and Patients without hemispheric lesion were tend to the right hemisphere superiority; (2) the performance of the patients with right hemispheric lesion and diffuse cerebral lesion both were demonstrated more poor.
