A case of agraphia was studied in the framework of the information-processing approach and in relation to comparable studies on alexia. Three dissociations are of interest in this patient's picture: (a) in language production: impairment of writing without impairment of speech; (b) in writing: impairment of spelling without impairment of phoneme-grapheme conversion; (c) in visible language: impairment of writing without equivalent impairment of reading. The implications of these dissociations for any model of linguistic processes are discussed.
在信息处理方法的框架内，并结合对失读症的类似研究，对一例失写症病例进行了研究。该患者的情况中有三个分离现象值得关注：（a）在语言产生方面：书写受损但言语未受损；（b）在书写方面：拼写受损但音素-字素转换未受损；（c）在视觉语言方面：书写受损但阅读未出现同等程度的受损。本文讨论了这些分离现象对任何语言加工模型的意义。
