These findings support the sight that the honesty of phonological depictions plays an important function in the success of written language processing which sore place within the perisylvian language zone accurately generates a dissociation in between phonological dyslexia/dysgraphia and the sublexical phoneme-grapheme conversion processes required for non-word analysis and punctuation (Coltheart, 2006).

People with this dyslexia can still correctly match comparable non-orthographic types of the very same letter, duplicate a written letter, or identify a published letter according to its name or noise.
