Abstract

Autism spectrum disorder (ASD) is associated with marked heterogeneity in executive function (EF) abilities. EF components including inhibition and shifting are related to ASD core symptoms such as perspective taking, social communication, and repetitive behavior. Recent research suggests that multilingualism may have a beneficial impact on EF abilities, especially in children with ASD. However, there remains a lack of comprehensive understanding regarding the relationships between multilingualism, EF, and core symptoms in children with ASD. Here, we examined these associations in 7-12-year-old children with and without ASD (N = 116; 53 ASD, Mean age = 9.94 years). Results suggest that multilingual children have stronger parent-reported inhibition, shifting, and perspective-taking skills than monolingual children. Furthermore, we found a significant interaction between diagnosis and multilingual status on inhibition, such that the effects of multilingualism were stronger for children with ASD than typically developing (TD) children. Finally, we found indirect effects of multilingualism on perspective taking, social communication, and repetitive behaviors mediated by EF skills. These results demonstrate the supportive influences multilingual experience might have on bolstering EF and reducing ASD-related symptoms.
