This can make it difficult to read and spell. Children with this type of dyslexia may often have difficulty rhyming and blending audios to create words or reviewing sight words.
These difficulties can lead to the discordant profile of phonological dyslexia and dysgraphia where clients reveal serious punctuation disabilities although their word reading ability is normal. These findings sustain the sight that the stability of phonological depictions plays an essential role in the success of written language handling which sore place within the perisylvian language area dependably creates a dissociation between phonological dyslexia/dysgraphia and the sublexical phoneme-grapheme conversion processes needed for non-word analysis and punctuation (Coltheart, 2006).
