Parent interaction and child language development

Parent-child interactions are the foundational forum for language exposure and learning. We know from a wealth of evidence that higher amounts of language input and varied forms of language input provided by parents to their young children during these interactions enhances language development in typical development, which in turn confers long-term linguistic and academic advantages (Hart & Risley, 1995; Hoff & Naigles, 2002; Huttenlocher et al., 1991; Hurtado et al., 2008). These findings reveal that children implicitly keep track of language input, and develop better language abilities when immersed in rich input environments.

There has been less attention paid to the role of parental linguistic input in language development in children with Autism Spectrum Disorder (ASD). A clearer picture of the data that children with ASD have available to mine for language learning, as well as of specific relationships between aspects of the input and later language development, are essential for a comprehensive view of factors that contribute to language development in this population.

Our findings, culled from transcription of naturalistic parent-child play interactions, demonstrate that parents of children with ASD provide similar linguistic environments for their children as do parents of typically-developing children of the same language ability. Critically, we found that a rich and varied linguistic environment helps children with ASD build their later vocabulary, as is the case for other children. These findings highlight the key role caregivers and educators can have in the language development of children with ASD. In addition, they have significant implications for intervention approaches to facilitate language in ASD, supporting the use of full and complex rather than simplified language.
