This study examines relationships between mathematical problem-solving performance (in terms of strategies used and accuracy) and the main cognitive domains associated with mathematical learning (i.e. executive functions, verbal comprehension and social perception) of children with and without autism spectrum disorder (ASD and non-ASD resp.). The…

This study examined mathematics achievement in school-aged children with autism spectrum disorder (ASD), symptoms of attention-deficit/hyperactivity disorder (ADHD), or typical development (TD) over a 30-month period and the associations between cognitive and reading abilities with mathematics achievement in children with ASD. Seventy-seven…

In light of the known visuoperceptual strengths and altered language skills in autism, we investigated the impact of problem content (semantic/visuospatial) combined with complexity and presence of lures on fluid reasoning in 43 autistic and 41 typical children (6-13 years old). Increased complexity and presence of lures diminished performance,…

Students with autism spectrum disorder (ASD), though academically capable, can have difficulty succeeding in college. Evidence-based intervention to promote effective problem solving may improve quality of life, as well as success and satisfaction in college. This study adapted and piloted a group-based cognitive-behavioral intervention program,…

Despite frequent reports of academic success, individuals with high functioning autism or Aspergers Syndrome (HFA/AS) often manifest deficits in social abilities. These deficits can lead to daily difficulties, and negative long-term outcomes. Deficits in social competency are evident in this population from an early age, as children with HFA/AS…

To determine variations in cognitive characteristics, 10 nonretarded men with infantile autism, residual state, were compared with 15 severely dyslexic men and 25 controls on a neuropsychological test battery. The dyslexics showed a reduced digit span and the autistic group exhibited impaired problem-solving skills. (Author/JDD)

Background: The executive functions of inhibition, planning, flexible shifting of actions, and working memory are commonly reported to be impaired in neurodevelopmental disorders. Method: We compared these abilities in children (8?12 years) with high functioning autism (HFA, n = 17), attention deficit-hyperactivity disorder (ADHD, n = 21) and…

This paper reports the findings of a 20-week social adjustment enhancement curriculum for boys aged 8-12. The curriculum was designed to address three areas hypothesized to be deficient in persons with HFA, AS, and PDDNOS: emotion recognition and understanding; theory of mind; and executive functions/real life type problem solving. Parents…
