THE STRUCTURE OF GRAPHEMIC REPRESENTATIONS IN SPELLING - EVIDENCE FROM A CASE OF ACQUIRED DYSGRAPHIA

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. ''cross'' spelled cro os), it is argued that stored spelling representations are not simple linear sequences of letter tokens (e.g. C-R-O-S-S). Rather, it is prop osed that the graphemic representations processed by the cognitive spe lling mechanisms are multidimensional structures that encode separatel y letter position, letter identity, letter doubling, and consonant/vow el status.
