Joint attention and imitation are thought to facilitate a developmental cascade of language and social communication skills. Delays in developing these skills may affect the quality of children's social interactions and subsequent language development. We examined how responding to joint attention and object imitation skills predicted rate of…

It is common in intervention research to use measures of working memory either as an explanatory or a control variable. This study examines the contribution of cognitive abilities, including verbal working memory (WM) and attention, to language performance in first- and second-grade children. We assessed children (N = 414) on two forms of verbal…

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…

Efficient visual exploration in infancy is essential for cognitive and language development. It allows infants to participate in social interactions by attending to faces and learning about objects of interest. Visual scanning of scenes depends on a number of factors, and early differences in efficiency are likely contributing to differences in…

Purpose: Both theoretical models of infant language acquisition and empirical studies posit important roles for attention to speech in early language development. However, deaf infants with cochlear implants (CIs) show reduced attention to speech as compared with their peers with normal hearing (NH; Horn, Davis, Pisoni, & Miyamoto, 2005;…

Purpose: Correlates of receptive-expressive vocabulary size discrepancies may provide insights into why language development in children with autism spectrum disorder (ASD) deviates from typical language development and ultimately improve intervention outcomes. Method: We indexed receptive-expressive vocabulary size discrepancies of 65 initially…

Purpose: The purpose of this study was to understand how joint attention and sensory-regulatory features are related in early childhood and predict language and social-communication outcomes in preschool in order to build mechanistic theories that can inform early intervention directed at improving these outcomes. Method: Cross-lagged panel…

This study compared between the roles of the socio-pragmatic and data-driven aspects of caregiver input in the vocabulary development of both Typically Developing (TD) Children and children with Autism Spectrum Disorders (ASD). The role of Joint Attention (JA) and Supported Joint Engagement (SJE) episode types, as well as Follow-In (FI) Comments,…

This study examined the longitudinal associations between parent verbal responsiveness and language 3 years later in 34 toddlers with a diagnosis of an autism spectrum disorder. Parent-child play samples were coded for child engagement and communication acts and for parent verbal responsiveness. Measures of responsive verbal behaviors were used to…

Purpose: The authors examined longitudinal associations between 2 categories of parent verbal responsiveness and language comprehension and production 1 year later in 40 toddlers and preschoolers with a diagnosis of an autism spectrum disorder (ASD). Method: Parent-child play samples using a standard toy set were digitally captured and coded for…

Elucidating the neural basis of joint attention in infancy promises to yield important insights into the development of language and social cognition, and directly informs developmental models of autism. We describe a new method for evaluating responding to joint attention performance in infancy that highlights the 9- to 10-month period as a time…

Preschoolers with severe autism and minimal speech were assigned either a discrete trial or a naturalistic language treatment, and parents of all participants also received parent responsiveness training. After 12 weeks, both groups showed comparable improvement in number of spoken words produced, on average. Approximately half the children in…

Joint attention (JA), the ability to share attention to an object or event with another person, is one of the earliest identified deficits in autism spectrum disorders (ASD) and directly influences language and social development. There are several effective assessments of JA for young children (e.g., Mundy et al., 2003), but none are appropriate…

Joint attention (JA), which occurs when two individuals focus on the same object or event, plays a critical role in social and language development. Two major kinds of joint attention have been observed: response to joint attention (RJA), in which children follow the attentional focus of their social partners, and initiation of joint attention…

Systematic longitudinal observations were made as typically developing toddlers and young children with autism and with Down syndrome interacted with their caregivers in order to document how joint engagement developed over a year-long period and how variations in joint engagement experiences predicted language outcome. Children with autism…
