Research on sex differences in the language of children with Autism Spectrum Disorder (ASD) has been limited. Song et al. (2020) found that pronoun usage differs among ASD and TD girls and boys. Additionally, studies have shown that maze (i.e. intervals of disfluent speech) usage distinguishes ASD and TD children but it is unclear whether these differences are also influenced by sex. This study aims to compare usage rates of "we" (1st person plural) pronouns, "they" (3rd person plural) pronouns, and mazes in ASD and TD girls and boys.
