Cultivating the imagination: Caregiver input during pretend play with toddlers at elevated likelihood for autism.

Toddlers with autism spectrum disorder (ASD) may exhibit less pretend play than their neurotypical counterparts. Previous research suggests that caregivers' input during play influences children's play behavior, and children's behavior may in turn prompt caregivers of differently developing children to talk about play in different ways. Caregiver input about pretend play during toy play at home was examined at 18- and 36-months in toddlers with an older sibling with ASD, who are at elevated likelihood (EL) for ASD (n = 40), and toddlers with typical likelihood (TL) for ASD (n = 12).
