Models of writing processes postulate that abstract graphemic representations contain information about letter doubling independent of letter identity. We describe a patient, R.T., who made perseverative errors only in handwriting geminate letters, [e.g.: "CORTECCIA" (cortex)-->"CORTECCCIA"]. Perseveration was specific to orthography. To explain R.T.'s errors, we argue that after the selection of the correct graphic motor programs, the geminate feature induced a perseverative graphic behaviour. This form of dysgraphia supports the notion that graphemic representations contain specific information about letter doubling.
书写过程模型假定，抽象的字素表征包含与字母重复有关的信息，且与字母本身无关。我们描述了一位患者R.T.，他仅在手写双写字母时出现持续性错误，[例如：“CORTECCIA”（皮质）→“CORTECCCIA”]。这种持续性错误仅限于拼写方面。为了解释R.T.的错误，我们认为在选择了正确的图形运动程序后，双写特征引发了持续性的图形行为。这种书写障碍形式支持了字素表征包含有关字母重复的特定信息这一观点。
