Gestures are an important social communication skill that infants and toddlers use to convey their thoughts, ideas, and intentions. Research suggests that early gesture use has important downstream impacts on developmental processes, such as language learning. However, autistic children are more likely to have challenges in their gestural development. The current study expands upon previous literature on the differences in gesture use between young autistic and non‐autistic toddlers by collecting data using a parent‐report questionnaire called the MCDI–Words and Gestures at three time points, 12, 18, and 24 months of age. Results (N = 467) showed that high‐likelihood infants who later met diagnostic criteria for ASD (n = 73 HL‐ASD) have attenuated gesture growth from 12 to 24 months for both deictic gestures and symbolic gestures when compared to high‐likelihood infants who later did not meet criteria for ASD (n = 249 HL‐Neg) and low‐likelihood infants who did not meet criteria for ASD (n = 145 LL‐Neg). Other social communicative skills, like play behaviors and imitation, were also found to be impacted in young autistic children when compared to their non‐autistic peers. Understanding early differences in social communication growth before a formal autism diagnosis can provide important insights for early intervention. Lay Summary: As infants learn to talk, they use gestures to communicate. In this study, we used a parent‐report questionnaire to look at the group level differences of gestures in the first 2 years of life by comparing infants who later developed autism to infants who did not develop autism. We found that infants who later developed autism have fewer gestures and a slower rate of gesture growth compared to infants who did not develop autism. Play behaviors and imitation skills were also impacted in young autistic children when compared to their non‐autistic peers. [ABSTRACT FROM AUTHOR] |
