These findings support the view that the integrity of phonological representations plays a critical function in the success of composed language handling and that lesion location within the perisylvian language area accurately generates a dissociation in between phonological dyslexia/dysgraphia and the sublexical phoneme-grapheme conversion processes required for non-word reading and punctuation (Coltheart, 2006).
