Abstract
Deficits in cognitive flexibility are thought to underpin the core symptom of repetitive and restricted patterns of behaviour in autism spectrum disorder (ASD). Studies investigating this relationship, however, report inconsistent results. This is partly due to the variable nature of measures used to assess the construct of flexibility. The main purpose of this study was to investigate whether ASD traits differentially predict cognitive flexibility performance on lab-based neurocognitive measures relative to behavioural self-reports in a non-clinical sample of young adults. Our results indicate that ASD traits exclusively predict performance on behavioural self-reports of cognitive flexibility. These findings highlight the possibility that behavioural self-reports are a better index than lab-based neurocognitive measures to capture cognitive flexibility impairments in individuals with ASD.
