These difficulties can lead to the discordant profile of phonological dyslexia and dysgraphia where patients reveal extreme punctuation problems despite the fact that their word analysis capability is typical. These findings support the sight that the honesty of phonological depictions plays an essential duty in the success of composed language processing and that lesion area 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).

These jobs include word couple with migratable middle letters, such as cloud-could or parties-pirates. When the center letters migrate in between these words, they produce various other existing words, such as wind king or kind wing. The research affirms and prolongs the outcomes of a 1977 study by Shallice and Warrington that initially reported this form of dyslexia.
