This study examines visual attention capacities and inattentive/hyperactive behaviours in 77 children aged 4 to…

This study investigated the effects of response rate and attention focusing on performance of ADHD, clinical-control (CRNA) and non-clinical control children in response inhibition tasks. All children completed the "Go-NoGo" task, a computer-based task of attention and impulsivity. Focused attention on this task was manipulated using a priming…

The performance of 20 hyperactive and 26 comparison elementary-school boys on a spelling recognition task found that color facilitates attention to detail. Hyperactive children who practiced the task with all black letters first and color added later out-performed comparison children. (Author/JDD)

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…

Graphomotor output was assessed in children with attentional problems using the Repeated Patterns Test (RPT). Forty-eight subjects, ages 8 to 13, who met standard criteria for Attention Deficit Hyperactivity Disorder (ADHD), participated, of whom 24 had primarily Inattentive Type and 24 had Combined Type ADHD. Both groups had intact visuomotor…

The percent and characteristics of children who produced invalid profiles on two different continuous performance tests (CPTs) tasks were examined. Sixty-one children referred for attention deficit hyperactivity disorder (ADHD) assessment and 24 non-clinical control children (all children ages 5-16) were given the Test of Variables of Attention…
