It has been suggested that children with nonverbal learning disabilities (NLD) or Asperger's Syndrome (AS) may show difficulties with executive functioning. There were 3 groups in this study who completed a neuropsychological battery of visual-spatial, executive functioning, and reasoning tasks; AS (n = 37), NLD (n = 31), and controls…

This study examined the effectiveness of using "subject-performed tasks" to improve memory efficiency of eight autistic children. The procedure involved instructing children to carry out and later remember a series of actions. The procedure's effectiveness was attributed to autistic subjects' lack of verbal encoding strategies and…

Two studies examined executive functions in children with autism. Results indicated that subjects performed like normally developing children when either no arbitrary and novel rules were involved or the output was verbal. Results support the hypothesis that these children are challenged by executive tasks because they are unlikely to encode rules…

The follow-up study of 16 nonretarded autistic children as adults found that, though most were functioning poorly in terms of occupational-social outcome and psychiatric symptoms, four had essentially recovered. Severity of early autistic behavior was a poor predictor of outcome, but neuropsychologic measures of nonverbal problem solving were…

The profile of spatial ability is of interest across autism spectrum disorders (ASD) because of reported spatial strengths in ASD and due to the recent association of Asperger's syndrome with Nonverbal Learning Disability. Spatial functions were examined in relation to two cognitive theories in autism: the central coherence and executive function…
