Specific Reading Difficulty:
The Identification of Cognitive Déficits and the Information Processing Approach
Keywords:
Types of developmental dyslexia, Verbal memory, Phonological awareness, Processing of spoken and written languageAbstract
This is a review of literature about specific reading difficulty or dyslexia from two perspectives: the identification
of cognitive déficits and the information processing approach. The data indicate that the main difficulty of the dyslexics seems
to be associated with déficits in verbal memory and in the segmentation and blending of phonemes. Recently, the possibility
of another type of dyslexia, resulting from a specific difficulty with the lexical processing, has been also identified. It is
demonstrated how the processing models of speech and of written language can be used to explain and to define the nature of
the phonological and lexical difficulties of the dyslexic children.
