These troubles can bring about the discordant account of phonological dyslexia and dysgraphia where individuals show serious spelling disabilities even though their word analysis capacity is regular. These searchings for sustain the sight that the stability of phonological representations plays a vital function in the success of composed 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 analysis and spelling (Coltheart, 2006).
