Abstract

Describing how caregivers' talk to their autistic children, and how their talk may influence social and language outcomes, has important implications for developmental theory and intervention research. In this systematic literature review, we examine 294 caregiver talk variables extracted from 65 studies, provide a narrative overview of research findings, and link measurement approaches to various theories of language development. The majority of variables included only talk directed to children (90%), and specified the speech act being performed (57%). More than one-third of variables measured talk that was responsive to children's attention, activities, or communication (38%), and slightly less than a third measured variables that elicited children's communication or engagement. Semantic aspects of talk were specified in 41% of variables, structural features were measured in 20% of variables, and suprasegmental features were measured in only 1% of variables. Talk quantity (without reference to other aspects of talk) was measured in 8% of variables. We found strong support that talk related to children's attention is implicated in autistic children's language development, but this construct has been measured inconsistently in terms of semantic, structural, and functional features. There is also evidence for bi-directional relationships between caregiver's talk and autistic children's development on a variety of semantic and structural variables. LAY SUMMARY: In our review, we found many differences in how researchers measured caregiver's talk, but also some promising leads. Researchers should continue examining caregiver talk related to children's focus of attention to clarify how this type of language contributes to autistic children's development. We also found interesting research on how children influence caregiver's talk, and encourage researchers to continue to study how this occurs.
