These troubles can cause the discordant profile of phonological dyslexia and dysgraphia where people reveal severe punctuation disabilities despite the fact that their word analysis ability is regular. These findings support the sight that the integrity of phonological depictions plays a vital role in the success of created language processing which lesion area within the perisylvian language zone reliably creates a dissociation between phonological dyslexia/dysgraphia and the sublexical phoneme-grapheme conversion procedures required for non-word analysis and spelling (Coltheart, 2006).
Speech language pathologists can aid children with phonological dyslexia boost their skills by working with sounding out unknown words and constructing their tank of well-known sight words.
