Letter order - People with dyslexia may also reverse the order of two letters, especially when the final, incorrect, word looks similar to the intended word.
The problems underlying this type of dyslexia are related directly to memory and coding skills that allow representation of printed letters and words, not to poor phonological processing.

Surface dyslexia was imitated by damaging the orthographic lexicon so that the program made more errors on irregular words than on regular or non-words, just as is observed in surface dyslexia. [6] Phonological dyslexia was similarly modeled by selectively damaging the non-lexical route thereby causing the program to mispronounce non words.
Dysorthography is a disorder of spelling which accompanies dyslexia by a direct consequence of the phonological disorder. [1] [2] In the American classification from the American Psychiatric Association (APA) and the classification from the World Health Organization (WHO), it is a subtype of specific learning disorder with impairment in written expression.
The term dyslexia comes from the Greek words 'dys' meaning 'impaired', and 'lexis' meaning 'word' and is used to describe disorders of language concerning reading and spelling. Numerous models and hypotheses have been proposed in attempt to explain the broad range of symptoms experienced by deep dyslexics, but a definite consensus has yet to be ...
