  • Title: Gesture Production in Toddlers with Autism Spectrum Disorder.
    Author: Mishra A, Ceballos V, Himmelwright K, McCabe S, Scott L.
    Journal: J Autism Dev Disord; 2021 May; 51(5):1658-1667. PubMed ID: 32808150.
    Abstract:
    Children with Autism Spectrum Disorder (ASD) demonstrate delayed and atypical communication development. These deficits constitute a core criterion for the diagnosis of ASD, though information regarding gestural communication in toddlers with ASD remains limited. The present investigation implemented a robust gesture classification system in order to obtain quantitative measures of gesture production in a cohort of toddlers with ASD (n = 40) and controls (n = 40) during 10-min, play-based interactions with caregivers. Children with ASD produced fewer overall gestures and gesture subtypes compared to controls. The ASD group also displayed atypical patterns of gesture production. These findings highlight the need for evidence-based screening, assessment, and intervention protocols pertaining to gestural communication in toddlers with ASD.
