Abstract: | This investigation compared the behavior ratings and psychometric profiles of children with attention deficit disorders (ADD) and children with developmental reading disorders (DRD). ADD children showed no qualitative reading or spelling problems, although they were slightly behind expected levels of academic achievement. DRD children were significantly more impaired in academic attainment and showed evidence of qualitative disturbances in reading and spelling. DRD subjects did not differ from control subjects on ratings of hyperactivity, which was one of the defining variables of the ADD group. This evidence is interpreted as adding to a growing testimony that indicates that ADD and DRD are distinctly separate groups of disorders. |
