Conceptual problem-solving in highly verbal, nonretarded autistic men.

J M Rumsey

    Journal of Autism and Developmental Disorders
    |March 1, 1985
    PubMed
    Summary

    Highly verbal men with infantile autism showed significant deficits in rule formulation and perseveration on the Wisconsin Card Sorting Test, but these did not correlate with social-adaptive functioning.

    Area of Science:

    • Neuroscience
    • Psychology
    • Developmental Disorders

    Background:

    • Infantile autism is a complex developmental disorder with varied presentations.
    • Frontal system dysfunction is hypothesized to play a role in autism.
    • Cognitive deficits in autism require further investigation.

    Purpose of the Study:

    • To investigate conceptual problem-solving abilities in highly verbal men diagnosed with infantile autism.
    • To assess social-adaptive functioning in the same autistic sample.
    • To explore the relationship between cognitive deficits and social-adaptive functioning in autism.

    Main Methods:

    • The Wisconsin Card Sorting Test (WCST) was administered to nine autistic men and ten matched controls.
    • Social-adaptive functioning was assessed using a standardized measure.
    • Performance of the autistic group was compared to controls and published norms for brain-damaged patients.

    Main Results:

    • Autistic participants exhibited significant deficits in rule formulation on the WCST.
    • Perseverative tendencies were significantly higher in the autistic group compared to controls.
    • No significant correlation was found between WCST performance deficits and social-adaptive functioning levels.

    Conclusions:

    • The findings suggest specific executive function deficits, particularly in rule-based learning and cognitive flexibility, in this autistic sample.
    • The lack of correlation between cognitive and social deficits highlights the heterogeneity of autistic disorder.
    • The results support hypotheses linking frontal-subcortical dysfunction to certain autistic traits.
