These searchings for sustain the view that the stability of phonological representations plays a vital role in the success of written language processing which sore place within the perisylvian language zone dependably produces a dissociation between phonological dyslexia/dysgraphia and the sublexical phoneme-grapheme conversion procedures needed for non-word reading and spelling (Coltheart, 2006).
