Abstract

To investigate the relationship between cognitive and social functioning, 20 Israeli individuals with
HFASD aged 8–12 and 22 age, maternal education, and receptive vocabulary–matched preadolescents with typical development (TYP) came to the lab with a close friend. Measures of abstract reasoning, friendship quality, and dyadic interaction during a play session were obtained. As hypothesized, individuals with HFASD were significantly impaired in abstract reasoning, and there were significant group differences in friend and observer reports of friendship quality. There also was consistency in reports between friends. Two factors—‘‘relationship appearance’’ and ‘‘relationship quality’’ described positive aspects of the relationships. Disability status and age related to relationship appearance. Proband abstract reasoning was related to
relationship quality.
