Two patients with acquired dysgraphia were reported. The patients' performance in various written and oral spelling tasks converge in support of the hypothesis that they have selective damage, within the spelling system, to the Graphemic Buffer. Although the patients present with comparable patterns of error types, they differ in the distribution of errors as a function of letter position in words. The patients' patterns of errors are compared to previously reported patterns of spelling errors in dysgraphic patients and are discussed in terms of hypothesized mechanisms that operate on the representations that are stored in the Graphemic Buffer.
报告了两名获得性书写障碍患者。这两名患者在各种书面和口头拼写任务中的表现趋同，支持了这样一种假设，即他们在拼写系统内对字形缓冲器有选择性损伤。尽管这两名患者呈现出相似的错误类型模式，但他们在错误分布上因单词中字母位置的不同而有所差异。将这两名患者的错误模式与先前报道的书写障碍患者的拼写错误模式进行了比较，并根据作用于存储在字形缓冲器中的表征的假设机制进行了讨论。
