Background & Aims: Many young children with autism spectrum disorder (ASD) demonstrate striking delays in early vocabulary development. Experimental studies that teach the meanings of novel nonwords can determine the effects of linguistic and attentional factors. One factor that may affect novel referent selection in children with ASD is…

Despite well-documented attention deficits in children with intellectual and developmental disabilities (IDD), distinctions across types of attention problems and their association with academic attainment has not been fully explored. 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…

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 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…

A visual orienting task was given to 11 high functioning male adolescents and adults with autism. Findings suggested that autistic people have difficulty processing briefly presented cue information and problems disengaging and shifting attention within the visual modality. Results support previous ideas that attentional dysfunction may underlie…

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…
