Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by behavioral difficulties in social communication and social interaction, as well as restrictive or repetitive interests or behaviors. It is currently debated whether people with ASD have altered metacognition, defined as the ability to evaluate one’s own cognitive processes in various domains. Currently, the results are mixed. While some studies suggest that metacognition is impaired in ASD, other studies have not observed differences compared to neurotypical participants. The main goal of this study was to contribute to this debate, through the study of metacognition in ASD traits in a sample of neurotypical individuals using an online experiment and a bias-free measure of metacognition. Preliminary results will be discussed.
