These findings support the sight that the stability of phonological representations plays a critical duty in the success of composed language processing which lesion location within the perisylvian language area dependably produces a dissociation in between phonological dyslexia/dysgraphia and the sublexical phoneme-grapheme conversion processes needed for non-word analysis and spelling (Coltheart, 2006).
Speech language pathologists can aid kids with phonological dyslexia improve their abilities by dealing with sounding out unfamiliar words and constructing their tank of well-known view words.

These tasks include word pairs with migratable middle letters, such as cloud-could or parties-pirates. When the middle letters migrate between these words, they develop various other existing words, such as wind king or kind wing. The study corroborates and extends the results of a 1977 study by Shallice and Warrington that first reported this type of dyslexia.
