Add Students With and Without Dyslexia Differ in Sensitivity to Rhyme and Alliteration

Abstract

Children with attention deficit disorder (ADD) and dyslexia (n = 82) made significantly more errors than normally reading children with ADD (n = 83) on a simple auditory test of phonological sensitivity to rhyme and alliteration (Bradley, 1984). A subgroup of children with dyslexia who were sensitive to rhyme and alliteration had higher scores on the Wechsler Intelligence Scale for Children-Revised (WISC-R) Spatial factor than a dyslexic subgroup who were phonologically insensitive. In multiple regression analyses, age-corrected phonological sensitivity scores contributed significantly to the prediction of both reading and spelling Wide Range Achievement Test (WRAT) scores, this beyond the contribution of WISC-R variables. Of interest for dyslexia subtyping theories, Spatial factor scores had a subtractive effect in these regression analyses.
