Producing pronouns involves linguistic and social-cognitive knowledge because children must learn words and understand pronouns' changing referents. This study examined pronoun production longitudinally in young children with autism spectrum disorder (ASD; n = 15), whose social-cognition might impair pronoun use, and in typically developing (TD; n…

The evidence comes from an artificial language…
