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.

Remediation of acquired dysgraphia as a technique for testing interpretations of deficits

Abstract This article describes a brain-damaged patient, J.E.S., whose pattern of impaired spelling suggested deficits affecting the graphemic output lexicon, the graphemic buffer, and the

VOWELS IN THE BUFFER: A CASE STUDY OF ACQUIRED DYSGRAPHIA WITH SELECTIVE VOWEL SUBSTITUTIONS

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.

The Contribution of Attentional Mechanisms to an Irregularity Effect at the Graphemic Buffer Level

The results point to an impairment of the graphemic buffer, i.e., the processing stage where abstract orthographic representations are temporarily stored while planning the written production, and it is shown that when focusing attention on the irregularity becomes necessary, this can cause a detriment to the surrounding graphhemic constituents.

The Impact of Deep Dysgraphia on Graphemic Buffer Disorders

Abstract This article describes an investigation into the residual writing skills of a severely dysgraphic patient (DA). We found that they were powerfully influenced by a number of lexical variables

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 of

Serial Order Effects in Spelling Errors: Evidence from Two Dysgraphic Patients

This study reports data from two dysgraphic patients, TH and PB, whose errors in spelling most often occurred in the final part of words, and which pattern of performance locates their deficit to the mechanism that keeps graphemic representations active for further processing.

Pure Dysgraphia with Relative Sparing of Lower-Case Writing

Patterns of Dysgraphia in Primary Progressive Aphasia Compared to Post-Stroke Aphasia

Structural imaging techniques found that damage to the left extrasylvian regions, including the uncinate, inferior fronto-occipital fasciculus, and sagittal stratum, was significantly associated with impairments in access to orthographic word forms and semantics.

A phonological dysgraphic syndrome is documented in a left handed man with a right-hemisphere lesion. His spelling was significantly affected by word length but neither word frequency nor the

Six right-handed patients with acquired right hemisphere lesions who suffered from reading disability had paralexic errors of a very characteristic, consistent, and hitherto undescribed type, which could be reproduced experimentally under the controlled conditions of tachistoscopic presentation of written material.
