Purpose: Gesture delay in autistic infants and toddlers has been widely reported. The developmental trajectory of gesture production during early childhood is understudied. Thus, little is known about the possible changes of gesture production over time. The present study aimed to document the development of gesture production in autistic children and examine whether child-based factors (chronological age and initial language skills) predicted gesture development. Method: A total of 33 Chinese-speaking autistic children ( M age = 56.39 months, SD = 8.54 months) played with their parents at four time points over a 9-month period. Their speech was transcribed, and their gestures were coded from parent–child interaction. Multilevel modeling analysis was used to investigate the development of gesture and its associated factors. Results: The total number of gestures produced by autistic children decreased over time. Among different factors, children's initial age significantly and negatively predicted children's gesture production, while initial language positively predicted children's gesture production. Conclusions: Gesture delay persists in preschool age. The decline in gesture production was associated with children's age and initial language ability. These findings shed light on the difficulties surrounding gesture use in autistic children.
