Comparison of 24 elementary school-age children with attention deficit hyperactivity disorder (ADHD) and 20 children with attention deficit disorder without hyperactivity (ADD/noH) on a comprehensive neuropsychological assessment found math achievement test scores for students with ADD/noH were significantly lower than those for students with…

Fifty-five dyslexic and 30 normal readers (8-12 years old) were administered the K-ABC. Normal readers demonstrated significantly higher scores on the cognitive subtests of "Hand Movements,""Number Recall, Word Order," and "Matrix Analogies" as well as on each achievement subtest, the "Sequential" and "Achievement" factors, and the "Mental…

The study examined the developmental lag hypothesis for learning disabilities by evaluating dichotic listening ability using both free recall and directed attention conditions in 24 learning disabled (LD) adults. Findings indicated LD adults showed similar deficits in lateralized selective auditory linguistic processing as children with LD. (DB)

The article addresses the neuroimaging, electrophysiological, and postmortem evidence concerning the neurological basis of dyslexia and concludes that inconsistent findings may be related to limitations of investigative technologies. Correlates of reading ability and disability are discussed in a developmental-neuropsychological context.…

The article focuses on the factors that have led to the current interest in the neuropsychology of learning disorders. The validity of the neuropsychological model is examined. Research regarding the neurobiological basis of learning disorders, cerebral asymmetries, and neuropsychological assessment batteries for learning disabilities are…

The author reviews implications of the previous four papers on the neuropsychological approach to learning disabilities (ED 161 035-038), notes the importance of an interdisciplinary approach, discusses potential valuable test batteries, and emphasizes the need for appropriate training in neuropsychology psychologists and teachers.

Issues and developmental considerations in outcome and treatment of head injury in children are considered. Focus is on appropriate assessment practices in the areas of psychoeducational development, motor and cognitive deficits, and neuropsychological deficits. (Author/DB)

The exploratory study examined patterns of regional cerebral blood flow in a surface and a deep dyslexic during reading. Significant differences in gray matter blood flow were found between subjects and normal controls. Also differences existed between the surface and deep dyslexic in the distribution of cortical perfusion. (Author/DB)

This article reviews Bakker's developmental neuropsychological model (the Balance Model) of reading development (EC 602 750), notes the need for validating research before employing these procedures in clinical practice, and raises some conceptual problems such as evidence that learning disability subtypes evolve over time. (Author/DB)

Morphometric analysis of magnetic resonance imaging scans revealed that, compared to nondisabled controls, the seven children with attention deficit hyperactivity disorder had a smaller corpus callosum. Results suggest that subtle differences may exist in the brains of these children and that deviations in normal corticogenesis may underlie the…

This study compared parent and teacher behavioral ratings for 77 children (ages 5-16) diagnosed as having attention deficit disorder with hyperactivity (ADD/H), attention deficit disorder without hyperactivity (ADD/WO), or learning disabilities (LD). ADD/WO and LD children were rated similarly on symptoms of withdrawal and impulsivity but differed…

A study compared the reaction time and efficiency of cognitive processing on a speeded classification task, involving 43 children with attention deficit disorder/hyperactivity, 22 children with attention deficit disorder without hyperactivity, and 16 controls, aged 6-13. It was found that the children's diagnoses could not be distinguished on…
