The Production of Pronouns and Verb Inflections by Italian Children with ASD: A New Dataset in a Null Subject Language.

Abstract

The language of children with autism spectrum disorder (ASD) is often characterized by difficulties with pronouns. The underlying reasons for such difficulties are still unclear. This study is the first to test the abilities of children with ASD who speak Italian, a language in which overt subject pronouns are optional but verbs obligatorily feature person-referencing morphology. We found that Italian children with ASD were less accurate than typically-developing (TD) Italian children in the production of first-, second-, and third-person singular pronouns, avoiding pronouns in favor of nouns or names more often than controls. Moreover, children with ASD produced more overt pronouns than null pronouns in marked contexts, compared to TD children. These phenomena can be accounted for by difficulties with pragmatics.
