Abstract

Studies of executive function (EF) in autism spectrum disorder (ASD) report mixed findings. Confounds include EF domain assessed and co-occurring neurodevelopmental diagnoses. Performance on EF tasks and everyday function were significantly different when autistic adults (n=110) were compared with matched controls (n=31). Clinical impairment on response initiation and verbal fluency tasks were significantly more likely in the ASD group although 35.8% of the group showed no impairment on EF measures. Factor analysis revealed a single unifying EF construct rather than a selective pattern of impairment. Dysexecutive behaviours frequently reported in the ASD group, were unrelated to ASD symptoms, EF task performance or co-occurring conditions. Findings suggest autistic adults can experience clinically significant EF difficulties and /or dysexecutive behaviours that impact everyday life.
