Double deficit (education)
From Wikipedia, the free encyclopedia
Main articles: Dyslexia and Theories of dyslexia
The double-deficit theory of dyslexia[1][2] proposes that a deficit in two essential skills gives rise to the lowest level of reading performances, constituting the most severe form of dyslexia.
[edit] Reading ability
The ability to read is believed to depend on two skills:
- Phonological processing skills make up the ability to identify and manipulate sounds in speech.
- Rapid automatized naming compose the ability to translate visual information whether of letters, objects or pictures into a phonological code.[3]
