Dyslexia and language / phonology
Based on more recent research and experience, there is now focus on dyslexia being associated with a form of specific language difficulty, and that the Reading and writing problems primarily occur at word level. Such definitions also disregard intelligence.
Dyslexia and normal Reading and writing problems
An assessment which is often used as the basis for a diagnosis of dyslexia in practise, is to compare the persons reading skills with that of others of the same age.
The theory that specific and lasting phonological difficulties are associated with dyslexia has a solid foundation and strongly standing in research communities. Nevertheless, there are unanswered questions associated with dyslexia and the reasons for it.
