These findings support the sight that the honesty of phonological depictions plays an essential duty in the success of created language handling which lesion location within the perisylvian language zone reliably generates a dissociation in between phonological dyslexia/dysgraphia and the sublexical phoneme-grapheme conversion procedures needed for non-word reading and spelling (Coltheart, 2006).
