Nonverbal turn taking, defined as back-and-forth exchanges, may be used to convey instrumental or social intent. It has been theorized that social turn taking is foundational to joint attention and, as such, it has been incorporated as a component of early interventions for children with autism, who often have challenges in joint attention competency. The purpose of this study was to analyze the relationships between two turn-taking functions and joint attention as observed during interactions between 20 toddlers with autism who received intervention and their caregivers. It was hypothesized that socially driven turn taking would be positively related to joint attention, but instrumentally motivated turn taking would not. Video analysis revealed a positive relationship between social turn taking and joint attention, but not between instrumental turn taking and joint attention. While not causal, the findings support the promotion of social content in intervention and the concept that social turn taking may be a precursory competency to joint attention.
