From Using Tools to Using Language in Infant Siblings of Children with Autism

Abstract: Forty-one high-risk infants (HR) with an older sibling with autism spectrum disorder (ASD) were observed longitudinally at 10, 12, 18 and 24 months of age during a tool use task in a play-like scenario. Changes in grasp types and functional actions produced with a spoon were assessed during elicited tool use. Outcome and vocabulary measures were available at 36 months, distinguishing: 11 HR-ASD, 15 HR-language delay and 15 HR-no delay. Fewer HR-ASD infants produced grasp types facilitating spoon use at 24 mont… Show more

“…In HR infants functional action production at 10 months predicted respectively word comprehension (12 months) and production (24 and 36 months). The results of this study suggest the presence of impairments in purposeful actions in infants going on to receive ASD diagnosis and of a relationship between functional action production and communication [ 35 ]. Also postures have been considered.…”

“…How might this reduction in object exploration impact the development of communication and language? One area where these effects appear to be evident is the development of play actions and gestures involving object manipulation (e.g., holding a phone to the ear; Sparaci et al, 2018). These actions and gestures emerge toward the end of the first year, are produced during interactions with caregivers, index emerging symbolic abilities, and are closely related to the development of language (Bates et al, 1979).…”

“…Also, longitudinal studies examining infants and toddlers high-risk for ASD came to the fore. In the study of Sparaci and colleagues [25] forty-one high-risk infants (HR) with an older sibling with ASD were observed longitudinally at 10, 12, 18 and 24 months of age during a tool use task in a playlike scenario. Changes in grasp types and functional actions produced with a spoon were assessed during elicited tool use.…”
