The Perception & Action Podcast

The Perception & Action Podcast

Exploration of how psychology and sports science research can be applied to improving performance, accelerating skill acquisition and designing new technologies in sports and other high performance domains. Hosted by Rob Gray, professor of Human Systems Engineering at Arizona State University, the podcast will review basic concepts and discuss the latest research in these areas.
