These problems can cause the discordant account of phonological dyslexia and dysgraphia where individuals show severe spelling impairments even though their word analysis capacity is regular. These searchings for support the view that the integrity of phonological representations plays a crucial role in the success of created language handling which sore place within the perisylvian language zone reliably produces a dissociation between phonological dyslexia/dysgraphia and the sublexical phoneme-grapheme conversion procedures needed for non-word analysis and spelling (Coltheart, 2006).
