Abstract
Pragmatic language (PL) is defined as the ability to use language effectively in communicative exchanges. Previous findings showed that deficits in PL are a core characteristic of the communicative profile of individuals with autism spectrum disorder (ASD). While different lines of research have revealed a close link between PL and theory of mind (ToM), and between PL and executive functions (EFs), to our knowledge, few studies have explored the relationship between these three domains in children with ASD, and their results have been contradictory. The present study thus aimed to contribute to our understanding of PL in children with ASD and to analyze the underlying mediating role of ToM and EFs. PL is a complex and multifaceted construct. In the present study, we focused on two specific aspects, such as the comprehension of nonliteral language, and the ability to make inferences. After testing 143 participants (73 with ASD), our results confirmed that impairments in PL are a crucial feature of the ASD profile. Children with ASD were also more impaired than their typically developing peers in both ToM and EFs. When the mediating role of ToM and EFs on PL was considered, it emerged that only ToM contributed significantly to the relationship between group and PL. We discussed the potential importance of interventions not focused exclusively on PL, but also involving ToM. LAY SUMMARY: In everyday life, we use pragmatic language to interact successfully with others. Individuals with autism experience significant difficulty in pragmatic language, showing consequent impairments in communication. This study compared the comprehension of nonliteral language, and the ability to make inferences of children with autism and children with typical development, focusing on the role of social and cognitive abilities. Children with autism had difficulties in pragmatic language compared to children with typical development. In addition, the capacity to consider the perspective, intentions and beliefs of other people contributed significantly to the pragmatic language. Autism Res 2021, 14: 932-945.
