The aim of the study was to examine how goal-setting skills of children with attention-deficit/hyperactivity disorder (ADHD) can be predicted with elements of working memory. The study involved 30 children with an ADHD diagnosis and 30 healthy volunteers. The IQ of the participants was assessed, and ADHD symptoms were evaluated by parents. Each of…

This commentary addresses issues concerning (a) the measurement of numbers, letters, and words versus cognitive processes in early screening batteries, and (b) comorbid associations of reading, math, and attention disorders. Based on reading prediction studies, assessments that include numbers should be most predictive of math outcomes. However,…

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…

This study assessed visual selective attention in children with attention difficulties compared to typically achieving children using the flanker task and the feature and conjunction visual search task. Results suggest that children with attention difficulties have a characteristic inability to restrict visual attention to a limited spatial area…

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.…

The article attempts to provide a definition of attention that has relevance for rehabilitation therapists working with the brain injured. A review of clinical studies suggests that, although behavioral aspects of attention are amenable to change and improvement, cognitive or information-processing changes are not so easily achieved.

This paper selectively reviews research on event-related potentials (ERPs) during cognitive processing among children with attention deficit disorder. Research indicates that performance deficits during sustained attention are coupled with reduced amplitude of the P3B component of the ERP, which may be increased with stimulants. P3B latency and…

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…

Data from three studies identified the cognitive deficits associated with reading difficulties as distinct from attentional deficits. The studies found consistent cognitive deficits (especially naming and phonological awareness) associated with difficulty in reading. Deficits were consistent across samples, developmental levels, definitions, and…

A study of 62 children (ages 7 to 12) with attention-deficit hyperactivity disorder (ADHD) and 62 controls found that behavioral variables established robust, statistically significant differences between groups. Children with ADHD also scored worse on 31 out of 61 neuropsychological variables, but obtained better scores on WISC-R Comprehension…

Factor analysis of the Swedish version of the Wechsler Adult Intelligence Scale-Revised on 88 adults with dyslexia showed a three-factor structure: a verbal comprehension (VC) factor, a perceptual organization (PO) factor, and a freedom from distractibility (FD) factor. The PO factor had the highest scores and the FD the lowest. (Contains…

Using cluster analysis, a study empirically divided 54 children with attention-deficit/hyperactivity disorder (ADHD) based on their Full Scale IQ and reading ability. Clusters had different patterns of cognitive, behavioral, and neurochemical functions, as determined by discrepancies in Verbal-Performance IQ, academic achievement, parent…

This study examined the utility of the Planning, Attention, Simultaneous, Successive (PASS) theory of intelligence as measured by the "Cognitive Assessment System" (CAS) for evaluation of children with attention-deficit/hyperactivity disorder (ADHD). The CAS scores of 51 Dutch children without ADHD were compared to the scores of a group…

A study examined central auditory processing ability of 15 children with attention-deficit hyperactivity disorder (ADHD), 15 children with ADHD and learning disabilities (LD), and 15 controls. Results indicated lower central-auditory-processing ability and significant correlations between reading and ADHD and reading and…

This study analyzed the performance of 30 children (ages 9-11) with central auditory processing disorders (CAPD), to test the validity of the Auditory Continuous Performance Test in differentiating between CAPD with and without attention deficit hyperactivity disorder (ADHD). Results indicated limited potential of the test in the differential…
