Purpose: This cross-sectional study aimed to depict expressive language profiles and clarify lexical–grammatical interrelationships in Mandarin-speaking preschoolers with autism spectrum disorder (ASD) during the administration of the simplified Chinese Psychoeducational Profile–Third Edition screening. Method: We collected naturalistic language samples from 81 (74 boys, seven girls) 2- to 7-year-old ( M age = 55.6 months, SD = 15.17) Mandarin-speaking children with ASD in clinician–child interactions. The child participants were divided into five age subgroups with 12-month intervals according to their chronological age. Computer-assisted part-of-speech tagging, constituency analysis, and dependency analysis addressed the developmental trajectories of early lexical and grammatical growth in each age subgroup. Results: Significant within-ASD differences were observed in content words, function words, and lexical categories. Nouns and verbs were the predominant lexical categories, while noun types overwhelmed verb types in children over 3 years old. The grammatical development of 5- to 6-year-old Mandarin-speaking children with ASD was better than that of 3- to 4-year-old children. The trends of syntactic structures, grammatical relations, and grammatical complexity in each age group were similar. Conclusions: Mandarin-speaking preschoolers with ASD produce more lexicons with increasing age. They preserve the noun bias as a universal mechanism in early lexical learning. Moreover, their developmental trajectories of grammatical growth were comparable in each age subgroup. In addition, their lexicons and grammar were synchronically developed during early language acquisition.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
