Lab Talk: Winona Snapp-Childs

The Speech Research Lab meeting this Friday (8/28) will feature a talk by IU postdoctoral fellow Winona Snapp-Childs on her research into relationships between perception and motor coordination. Her title and abstract are given below; all are invited and welcome to attend.

Winona Snapp-Childs, Indiana University, will present, "The Role of Perception in Coordinated Rhythmic Movement."

Abstract:
Coordinated rhythmic movements are fundamental and familiar forms of behavior (e.g. walking, running, drumming, and the like). Previous work has shown that bimanual rhythmic movement coordination is specifically structured. There are two forms of coordination that people can easily and spontaneously produce: 0° and 180°. Other coordination patterns can, but must, be learned. More recent studies have suggested that such movements are coupled perceptually (rather than neurally). I will present studies that provide evidence for the role of perception in coupling movements and investigate the perceptual information that is used. A non-linear dynamical model of perceptually-coupled rhythmic coordination will also be described briefly together with data that support the model.
