These searchings for sustain the sight that the stability of phonological representations plays a vital function in the success of composed language processing and that sore area within the perisylvian language area dependably creates a dissociation between phonological dyslexia/dysgraphia and the sublexical phoneme-grapheme conversion processes required for non-word analysis and punctuation (Coltheart, 2006).
