These findings sustain the sight that the honesty of phonological depictions plays an important 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).
