Hui Qiu; Xiao Liang – Journal of Autism and Developmental Disorders, 2024
This study aimed to explore the potential mediating role of sleep quality in the effect of physical activity (PA) intervention for improving executive functions (EFs) in children with attention-deficit hyperactivity disorder (ADHD). Participants aged 6 to 12 years old with a formal ADHD diagnosis were recruited from a local hospital. A total of 80…

Boo, Cynthia; Alpers-Leon, Nora; McIntyre, Nancy; Mundy, Peter; Naigles, Letitia – Journal of Autism and Developmental Disorders, 2022
Many studies have utilized standardized measures and storybook narratives to characterize language profiles of children with Autism Spectrum Disorder (ASD) and Attention Deficit/Hyperactivity Disorder (ADHD). They report that structural language of these children is on par with mental-age-matched typically developing (TD) peers. Few studies have…

Godoy, Priscilla B. G.; Shephard, Elizabeth; Milosavljevic, Bosiljka; Johnson, Mark H.; Charman, Tony – Journal of Autism and Developmental Disorders, 2021
Shared difficulties with cognitive control may play a role in co-occurring mental health problems frequently observed in autistic children. We investigated how different cognitive control processes (inhibitory control, conflict resolution, cognitive flexibility) associated with traits of autism spectrum disorder (ASD),…

Tan, Beron W. Z.; Pooley, Julie A.; Speelman, Craig P. – Journal of Autism and Developmental Disorders, 2016
This review evaluates the efficacy of using physical exercise interventions on improving cognitive functions in individuals with autism spectrum disorder (ASD) and/or attention deficit hyperactivity disorder (ADHD). This review includes a meta-analysis based on a random-effects model of data reported in 22 studies with 579 participants aged…

Speirs, Samantha J.; Rinehart, Nicole J.; Robinson, Stephen R.; Tonge, Bruce J.; Yelland, Gregory W. – Journal of Autism and Developmental Disorders, 2014
Autism spectrum disorders (ASD) are characterised by a unique pattern of preserved abilities and deficits within and across cognitive domains. The Complex Information Processing Theory proposes this pattern reflects an altered capacity to respond to cognitive demands. This study compared how complexity induced by time constraints on processing…

Malisza, Krisztina L.; Clancy, Christine; Shiloff, Deborah; Foreman, Derek; Holden, Jeanette; Jones, Cheryl; Paulson, K.; Summers, Randy; Yu, C. T.; Chudley, Albert E. – Journal of Autism and Developmental Disorders, 2011
Functional magnetic resonance imaging (fMRI) during performance of a hidden figures task (HFT) was used to compare differences in brain function in children diagnosed with autism disorder (AD) compared to children with attention-deficit/hyperactivity disorder (ADHD) and typical controls (TC). Overall greater functional MRI activity was observed in…

Ames, Catherine S.; White, Sarah J. – Journal of Autism and Developmental Disorders, 2011
Reports of co-morbid symptoms of ADHD in children with ASD have increased. This research sought to identify ADHD-related behaviours in a sample of children with ASD, and their relationship with the ASD triad of impairments and related cognitive impairments. Children with ASD (n = 55) completed a comprehensive cognitive assessment whilst a…

Semrud-Clikeman, Margaret; Walkowiak, Jenifer; Wilkinson, Alison; Butcher, Brianne – Journal of Autism and Developmental Disorders, 2010
The purpose of the study was to evaluate neuropsychological and behavioral rating measures of executive functions (EF) in children with two subtypes of ADHD, Asperger syndrome (AS), and controls. Relative to the control group, the clinical groups experienced more difficulty in EF. The AS group showed the most difficulty in emotional control,…
