An Italian patient with a pure dysgraphia who incorrectly spelled words and nonwords is described. The spelling errors made by the patient were not affected by lexical factors (e.g., frequency, form class) and were qualitatively the same for words and nonwords. The pattern of writing performance is discussed in relation to current models of writing and, specifically, in relation to the role of the Output Grapheme Buffer and Phoneme-Grapheme Conversion in writing.

Selective impairment of the Graphemic Buffer in acquired dysgraphia: A case study
TLDR
The case of an Italian dysgraphic patient, who showed a deficit of both written and oral spelling capacities, without significant differences between words and nonwords, is reported, consistent with the hypothesis that S.E.'s spelling disorder results from selective damage of the Graphemic Buffer. Expand
Pure Dysgraphia with Relative Sparing of Lower-Case Writing
TLDR
Cognitive analysis of a patient with acquired pure dysgraphia presents a peculiar dissociation between lower- and upper-case handwriting, suggestive of an impairment of the graphemic output buffer, which however revealed itself to different degrees in the two handwriting styles. Expand
The structure of graphemic representations in spelling: Evidence from a case of acquired dysgraphia
Abstract A single-case study of an acquired dysgraphic patient is presented. On the basis of the patient's pattern of spelling errors, and especially his errors on words with geminate letters (e.g.Expand
VOWELS IN THE BUFFER: A CASE STUDY OF ACQUIRED DYSGRAPHIA WITH SELECTIVE VOWEL SUBSTITUTIONS
TLDR
The case of a patient who recovered from a clinical picture of fluent aphasia to selective dysgraphia is reported, supporting the notion that the consonant-vowel status is a property of graphemic representations, and is compatible with that a common buffer is involved in spelling and reading. Expand
The Graphemic Buffer and attentional mechanisms
TLDR
Patients with acquired dysgraphia' 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. Expand
Developmental Dysgraphia as a Reading System and Transfer Problem: A Case Study
TLDR
It is suggested that limitations in the processing of the reading system were responsible for the lack of an extensive set of induced position-sensitive sublexical representations that are contextually dependent, which would have serious consequences for transfer to spelling. Expand
The Role of the Graphemic Buffer in Reading
We report the reading performance of an acquired dyslexic and dysgraphic whose impaired spelling had previously been shown to result from damage to the graphemic buffer. The analysis of thisExpand
The Role of the Graphemic BuŒer in Reading

Dysgraphia and selective impairment of the graphemic buffer
We report the linguistic analysis of a case of pure dysgraphia whose features suggest a selective deficit of the graphemic buffer. We discuss the neuropsychological pattern in the light ofExpand

TLDR
The integrity of the patient's lexical orthographic representations was assessed by having him decide whether or not pairs of words presented auditorily rhymed, and his spelling problems were probably due to difficulty in processing those representations. Expand
