This study investigates the referential choice of Mandarin-speaking children with autism spectrum disorder (ASD). The data consist of narratives from 16 children with ASD and 16 typically-developing (TD) children. The narratives were elicited using the wordless picture book Frog, where are you? Participants’ referential expressions were coded in terms of referential form, function, and adequacy. The results revealed that, compared with the IQ- and language-matched TD children, the children with ASD used significantly more pronominal forms for subsequent mentions, showed insufficient ability to use definite and indefinite noun phrases to mark the information status of referents, and made fewer adequate reintroductions. Additionally, this study demonstrated the potential of the three-category classification to advance our understanding of referential choice in ASD. The outcomes underscore the importance of analyzing referential adequacy across referential functions, and suggest that referential functions are not equally difficult.
