摘要
本文从自动书写、抄写、听写、看图书写、主动书写和书写相关能力检查几个方面研究了20例汉语失写症的书写行为。结果分出失语性、视空间性、惰性、失用性、镜像和完全性六种性质的失写,其中失语怀失写占绝大部分(18/20),每种性质的失写各具特点。作者认为失语性失写是大脑笔划提取程序或音义限定受到某种因素干扰时,信息提取发生错乱所致;视空间失写是由于正常、连续的视空间功能破坏所致;惰性失写是因大脑执行连续行为时根据需要变换指令的能力受到干扰和破坏所致。在不同类型的失写性质中存在着许多不容忽视重叠现象,这与大脑半球内部丰富的神经网络联系有关。
The writing behavior of 18 Chinese agraphic pa tients were studied on several aspects including auto- matic writing,copying,writing to dictation,picture writing,spontaneous writing and examination of relat- ed abilities,The results led to six types of agraphia,i. e.aphasic,visuo-spatial,inert,apraxic,mirror and complete agraphia with aphasic agraphia as the main part(18/20).Each type of agraphia has its own charac- teristic.At the end,the neuropsychological mechanisms of agraphia were discussed.
