摘要某些胼胝体损伤的患者表现出不寻常的书写困难，他们的非优势手的报道。这种缺陷被称为单侧失写症，经典解释为左半球语言中心和右半球运动区之间的分离。本研究的目的是调查的胼胝体损伤患者的双手的书写能力与非典型的惯用手模式（主要是左手，但右手的写作）谁表现出后遗症的左侧单侧书写困难。为了这个目的，患者被要求在口头拼写，右手和左手书写，有或没有视觉反馈的情况下产生416个单词。结果表明，在所有形式的病人产生一些语音上合理的错误，最有可能与病前拼写困难;然而，在左手写作模式（特别是没有视觉），他使相当数量的nonphonologicalall。
Abstract Certain patients with a lesion of the corpus callosum have been reported as exhibiting unusual writing difficulties with their non-dominant hand. This deficit has been termed unilateral agraphia and classically interpreted as a disconnection between left-hemisphere language centres and right-hemisphere motor areas. The present study was designed to investigate the writing abilities of both hands of a corpus callosum-lesioned patient with an atypical pattern of handedness (mostly left-handed but right-handed for writing) who showed sequelae of a left unilateral dysgraphia. For this purpose the patient was asked to produce 416 words in oral spelling, right-handed and left-handed writing with or without visual feedback. The results show that in all modalities the patient produces some phonologically plausible errors most likely related to pre-morbid spelling difficulties; however, in the left-handed writing modalities (particularly without vision), he makes a considerable number of non-phonologicall...
