Purpose: Conversational latency entails the temporal feature of turn-taking, which is understudied in autistic children. The current study investigated the influences of child-based and parental factors on conversational latency in autistic children with heterogeneous spoken language abilities. Method: Participants were 46 autistic children aged…

Improving social communication is a frequent goal of early autism services. However, it is unclear whether existing models of social communication align with the perspectives and priorities of key stakeholders, including parents, teachers, and expert clinicians. Stakeholder perspectives on social communication characteristics and priorities for…

The development of copying behaviours of a group of infants from 9 to 15 months of age is analysed. These behaviours are classified according to their type (mimetic or imitated) and function (instrumental, social or hybrid). The function of the behaviours is derived from observable indicators linked to dyadic interaction. Mimetic behaviours are…

It is well established that deictic gestures, especially pointing, play an important role in children's language development. However, recent evidence suggests that other types of deictic gestures, specifically show and give gestures, emerge before pointing and are associated with later pointing. In the present study, we examined the development…

Purpose: This longitudinal study assessed continuity and stability of productive language (vocabulary and grammar) and discourse features (turn-taking; asking and responding to questions) during mother-child play. Method: Parent-child language use in 119 Spanish-speaking, Mexican immigrant mothers and their children at two ages (M = 2.5 and 3.6…

Cross-lagged panel analysis was used to examine associations between two joint engagement variables; higher order supported joint engagement and higher order supported joint engagement that co-occurs with caregiver's follow-in talk (higher order supported joint engagement + follow-in), and expressive and receptive vocabulary in a group of young…

Schools are the portal through which many children with autism spectrum disorder access early intervention. Collaborating with teachers can be an effective way to implement evidence-based practices. In this study, teachers learned to embed strategies from the Joint Attention, Symbolic Play, Engagement, and Regulation intervention into the standard…

Purpose: Understanding variability sources in early language interaction is critical to identifying children whose development is at risk and designing interventions. Variability across socioeconomic status (SES) groups has been extensively explored. However, SES is a limited individual clinical indicator. For example, it is not generally directly…

Using a nationally representative sample of 3- and 4-year-old Spanish-speaking dual language learners (DLLs) attending Head Start (N = 654), this study examined whether mean levels of and variability in peers' English receptive vocabulary skills were associated with DLLs' English and Spanish receptive vocabulary skills in the spring. In addition,…
