Youngsters with this type of dyslexia may frequently have problem rhyming and mixing noises to create words or reviewing view words.
These troubles can lead to the discordant profile of phonological dyslexia and dysgraphia where clients show serious spelling disabilities although their word reading capability is typical. These searchings for sustain the sight that the stability of phonological depictions plays an essential duty in the success of created language handling which sore area within the perisylvian language area reliably produces a dissociation between phonological dyslexia/dysgraphia and the sublexical phoneme-grapheme conversion procedures needed for non-word analysis and punctuation (Coltheart, 2006).
