Reading is about being able to decode the graphic symbols used by a society to represent the sounds of speech. There are different writing systems developed by different cultures, and their are different languages in each writing system. Each writing system requires a different set of cognitive skills to enable the decoding of the writing system. So for instance it is possible to be bilingual in both Japanese and English and to be only dyslexic in English
There are two cognitive processes involved in the task of reading, the lexical and the sublexical. The lexical is a whole word process, and the sublexical is a phonics process. Unfortunately the marketing needs of both whole language and phonics program makers fail to recognise that we all need to develop both cognitive abilities to enable both good decoding skills and goos comprehension skills.
With regard to dyslexia, there are two types of dyslexia. Developmental Dyslexia, which has a genetic origin, and has three cognitive subtypes: auditory, visual, and attentional. So auditory processing problems, visual processing problems , attention problems or any combination of the three can cause the dyslexic symptom. Alexia or acquired dyslexia is the result of a severe brain injury, stroke, dementia or progressive illness and is about loosing the ability to read. It has been from Alexia that the Psycholinguistic models of how we learn to read have evolved.
And i was suggesting that we need an Educational Research Council run on the same lines as the Medical Research Council to initially collate the existing international neurological research about how we learn to communicate, and store information, and then carry out further research to advise those who run the UK education system. And to research and clarify the claims made by program makers who wish to sell their products to our schools.
