Neuropsychological profile on the WISC-IV of French children with dyslexia.
This study examined the pattern of results on the Wechsler Intelligence Scale for Children (WISC-IV; French version) for 60 French children with dyslexia, from 8 to 16 years of age. Although use of WISC-III failed to clearly identify typical profiles and cognitive deficits in dyslexia, WISC-IV offers an opportunity to reach these objectives with new indexes and subtests. The mean performance analysis showed a Working Memory Index (WMI) at a limit level, significantly lower compared to the three other indexes. The WMI was the lowest index for 68% of the population studied and was significantly weaker for children with phonological dyslexia compared to children with surface dyslexia. WISC-IV evidenced preserved language and reasoning abilities in contrast to limited verbal working memory efficiency. Theoretical and clinical implications are discussed.
