ABSTRACT
The purpose of the first cognitive studies on dyslexia that were concerned with phonological reading was to try to establish whether there did exist a reading process that would be functionally distinct from a lexical and/or semantic reading process. In 1979, J. Derouesne and M. F. Beauvois postulated functional distinction between two stages in the phonological reading process: a graphemic and a phonemic one. The graphemic stage is conceived as distinct both from visual analysis and from print-to-sound conversion. Since 1979 certain authors have been concerned by what could occur between grapheme-phoneme conversion and speech output. The chapter shows with a new case of acquired phonological alexia, L.B., that whether non-words are pseudohomophonic to a word does affect his performance and that this effect is not confined to the condition of visual similarity with real words. It specifies the level of the phonemic processing involved in phonological reading.
