Aspects of the spelling process: Evidence from a case of acquired dysgraphia

Abstract
A patient is described who presents with a pattern of impaired written and oral spelling performance that implicates a selective deficit to the Graphemic Output Lexicon: Intact ability to spell nonwords in the presence of severe spelling difficulty for words. Spelling errors primarily took the form of phonologically plausible responses (e.g., ‘courress’ for CHORUS). Homophone confusions (e.g., ‘none’ for NUN—A WOMAN DEVOTED TO RELIGIOUS LIFE) were also produced. Detailed analyses of the pattern of spelling errors were performed both to address questions about the general structure of lexical processes used in spelling (e.g., the ability to access graphemic representations in the output lexicon directly from the Phonological Input Lexicon) and to articulate further the structure of the Phoneme-Grapheme Conversion Mechanism.
