大脑半球损害病人的汉字抄写研究

对３７例左、右半球病变者进行汉字抄写等测查。结果发现：１．大脑半球病变影响汉字抄写，但左和右半球病变者、皮层和皮层下病变者、失语和非失语病人的汉字抄写成绩无明显差异；２．无论有无失语，抄写与听写都无相关；与画图的关系取决于文化背景，即文化水平低者（无读写能力）汉字抄写与临摹画图高度相关，并受半测空间疏忽影响，而有读写能力者汉字抄写不受以上因素影响。由此推测：不同的汉字书写方式有着不同的神经机制；无汉字读写能力者抄写过程主要与右脑有关，而有读写能力者汉字抄写时双脑并用。

A STUDY OF CHINESE CHARACTER COPYING IN PATIENTS WITH CEREBRAL LESION

This paper was designed to study Chinese-character-copying in 37 patients with cerebral lesions.The results showed that lesions of the cerebral hemisphere may lead to Chinese character copying disorder,but the degree of disorder had no statistical difference between the right side and the left side,between the cortical and the subcortical area, and no difference between patients with.aphasia and those with nonaphasia whether the patients were aphasic or not,there was no interrelation between copying and dictation, the relationship between copying of Chinese character and copying painting was dependent on the educational background,patients with less edeucation(not being able to read and write) showed significant interrelation between the ability of copying of the Chinese character and that of copying of painting and also under the influence of unilateral spatial neglect, while for the patients with reading and writing ability,the above mentioned factors could not be found in the copying of Chinese characters.It was suggested that different ways of writing Chinese characters had different neural mechanisms. The main process of copying for the persons who were not able to read and write was related to the right cerebrum, while that for the persons who were able to read and write was related to the usage of the right and left cerebrum.
