Attentional performance was examined in hyperactive and normal 10- and 14-year-old boys. Multivariate analyses followed by univariate tests indicated that both age groups of normal Ss were superior to hyperactive Ss in attentional performance while hyperactive adolescents demonstrated significant improvement with age only in coming to attention.…

This study investigated whether specific academic deficits were associated with attention-deficit disorder subtypes (with or without hyperactivity) with 40 elementary students. Results support the hypothesis that inattention exerts a specific and deleterious effect on the acquisition of arithmetic-computation skills. Implications for ADHD…

This study, with 17 young adults with attention deficit hyperactivity disorder (ADHD) and 62 without ADHD, found no significant correlations between full scale IQ and scores on the Test of Variables of Attention (TOVA). However, analysis of variance revealed that subjects with ADHD made more errors of omission on the TOVA than did controls.…

This study compared children with either attention deficit hyperactivity disorder (ADHD) (n=24), reading disability (RD) (n=33), both (n=9), or controls. Children with ADHD were characterized by difficulty with a visual search task whereas children with RD had difficulty with an auditory processing task. Specifically, children with ADHD…

Twenty elementary-grade boys with attention deficit hyperactivity disorder and 20 nondisabled boys worked on an arithmetic task during either high stimulation (music), low stimulation (speech), and no stimulation (silence). Although nondisabled children performed similarly under all three auditory conditions, the children with ADHD did somewhat…

This paper presents a model of differential diagnosis of attentional problems and reading disability that uses intra-individual differences in performance of tasks that vary in their requirement of sustained attention such as listening comprehension (high attention requirement) and reading comprehension (lower attention requirement). The validity…

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…

Questioning of teachers and mothers of 84 Israeli students (ages 7-10) classified as either hyperactive, learning disabled, both, or neither, found higher distractibility and hostility among hyperactive children whose families were also reported as less supportive. Learning-disabled students were characterized by dependent interpersonal relations…

Comparison of eight-year-old children with attention deficit hyperactivity disorder (ADHD) (n=21), learning disorder (LD) (n=12), or both (n=27) on neuropsychological measures found that ADHD children were impaired in control and inhibition of impulses; children with LD in phonological awareness, verbal memory span, storytelling, and verbal IQ;…
