Letter position dysgraphia.
The article describes AE, a Hebrew-speaking individual with acquired dysgraphia, who makes mainly letter position errors in writing. His dysgraphia resulted from impairment in the graphemic buffer, but unlike previously studied patients, most of his errors related to the position of letters rather than to letter identity: 80% of his errors were letter position errors in writing, and only 7% of ...
متن کاملMultiple Levels of Letter Representation in Written Spelling: Evidence From a Single Case of Dysgraphia with Multiple Deficits
In this paper, we report a detailed analysis of the impaired performance of a dysgraphic individual, AD, who produced similar rates of letter-level errors in written spelling, oral spelling, and typing. We found that the distribution of various letter error types displayed a distinct pattern in written spelling on the one hand and in oral spelling and typing on the other. In particular, noncont...
متن کاملThe role of the Graphemic Buffer in spelling: evidence from a case of acquired dysgraphia.
A dysgraphic patient is described whose deficit is hypothesized to arise from selective damage to the Graphemic Buffer. The patient’s roughly comparable difficulties in oral and written spelling and comparable spelling difficulties in written naming, delayed copy and spelling-to-dictation rule out the hypothesis of selective damage to either input or output mechanisms. More importantly, the nat...
متن کاملLetter selection and letter assembly in acquired dysgraphia.
OBJECTIVE We explored the constituents of the graphemic buffer in a patient with acquired dysgraphia and tested the hypothesis that the graphemic buffer is composed of 2 dissociable components: letter selection and letter assembly. BACKGROUND Research on dysgraphia has established the graphemic buffer as a component of the spelling mechanism, and the buffer is considered a short-term memory s...
متن کاملIntransigent Vowel-Consonant Position in Korean Dysgraphia: Evidence of Spatial-Constructive Representation
Dysgraphia due to a focal brain lesion can be characterized by substitution, transposition, deletion and/or addition errors of graphemes or strokes. However, those linguistic errors can be language-specific because the writing system of a given language may influence error patterns. We investigated a Korean stroke patient, a 57-year-old English teacher with dysgraphia both in Korean Han-geul [s...
