Debra Lieberman is a lecturer in the Department of Communication and a researcher in the Institute for Social, Behavioral, and Economic Research (ISBER) at UC Santa Barbara. Dr. Lieberman presents theory and research on the features of interactive health games that -- when well designed -- may influence players' health-related attitudes, learning, and behavior. The features include, for example, challenging game goals, a dramatic story line, and nurturing of game characters who need care. How do these and other game features enhance or detract from players' processing of health messages, and in turn what is their potential impact on health behavior change? Originally recorded October 18, 2007 at the University of California Santa Barbara. Less
