Communication and language development, early social cognition, parent-child interactions, typical and atypical developmental trajectories
My primary research focus is communication development from early moments of mutual alertness to complex conversations. I have been particularly interested in the transformation of joint engagement, the active sharing of object and events during social interactions. Through the study of both typical and atypical developmental paths, I hope to contribute to theoretical understandings of social and cognitive development and to inform applied efforts to facilitate early communication and language acquisition.
As an Emerita faculty member, I no longer direct a laboratory in the department where I mentor students. However, I continue to be an active researcher with several on-going projects. Right now, my primary work related to joint engagement is focused on how children share speech, music, and environmental sounds with caregivers. With funding from NICHD/NIH, I am collaborating with Roger Bakeman, Katharine Suma, and Diana Robins to describe how auditory joint engagement typically develops from 12 to 30 months and how developmental disorders including autism spectrum disorder (ASD) affect this development. In addition, I am continuing to study how ASD affects gesturing, how the quality of early joint engagement supports language and literacy development of young low-income children, and how best to refine strategies for the early detection of ASD.
In addition, Katharine Suma and I are working with research groups in several countries to adapt the Joint Engagement Rating Inventory (the JERI) and the Communication Play Protocol, two systematic observational methods that I developed with Roger Bakeman during our studies of joint engagement. Hopefully these techniques will provide a reliable and nuanced data that can be used to describe interactions in several cultural contexts and to assess the effectiveness of parent-focused interventions for children who are at risk for communication difficulties and language delay. Manuals detailing these procedures are available.
