Adolescent Health, Behavior Change, Curiosity, Human Behavior, Substance Abuse, Substance Use, Tobacco

David Lydon-Staley is an Assistant Professor at the Annenberg School for Communication at the University of Pennsylvania. Lydon-Staley鈥檚 research focuses on the unfolding of human behavior over short timescales (e.g., moment-to-moment, day-to-day) during the course of everyday life. The ebb and flow of momentary behavior may seem inconsequential, but the minutiae of everyday life, once tallied up over time, become the foundation for more enduring changes in our behavior, environment, and biology that occur on longer (e.g., years, decades) timescales. With this focus on short-term (on the daily or even finer timescales) dynamics in behavior, his research focuses on substance use, emotion regulation, and curiosity across the lifespan, with a particular focus on adolescence. He makes use of functional Magnetic Resonance Imaging (fMRI), experimental laboratory paradigms, and experience sampling methodologies coupled with intensive-longitudinal data and network analysis techniques.

Lydon-Staley鈥檚 work has been funded by the National Institute on Drug Abuse, the Jacobs Foundation, the International Society for the Study of Behavioral Development, the Center for Curiosity, and the Brain & Behavior Research Foundation. He received his bachelor鈥檚 degree in Psychology and English Literature from Trinity College Dublin, Ireland and his Ph.D. in Human Development & Family Studies from The Pennsylvania State University. Before joining Annenberg, he completed a postdoctoral fellowship in the Complex Systems Lab of Professor Danielle Bassett in the Department of Bioengineering at the University of Pennsylvania.

Behavior Change, Health Promotion, Leisure

As an Extension Specialist, Dr. Payne's overall goal is to improve health and well-being through research, education, and outreach programs that result in the delivery of quality and sustainable recreation, parks, and wellness programs/services. Her research examines the effects of leisure behavior on aspects of health and well-being among older adults. More specifically, she examines the relationship between leisure style and health of older adults with chronic conditions and the role of local parks and recreation agencies in health promotion and health behavior change. She has directed several statewide outreach and research programs such as the Illinois Rural Recreation Development Project, Illinois Senior Wellness Initiative, Take Charge of Your Health: Live Well be Well, and the Illinois Health Care Reform Initiative. Her work has been supported by the State of Illinois Division of Human Services, United States Department of Agriculture (USDA), the National Recreation Foundation, the National Institutes of Health (NIH) and the Robert Wood Johnson Foundation.

Kenneth E. Wallen, Ph.D.

Associate Professor of Human Dimensions of Fish and Wildlife

University of Idaho

Behavior Change, Social Influence, Social norms, Wildlife, Wildlife Management

Human behavior is the cause of many environmental, conservation, and societal issues but is also the means to solve them more readily. My lab focuses on human behavior, decision-making, and behavior change in the context of conservation and natural resources management. We use psychology and other social and behavioral science frameworks in combination with survey methods, experiments, and statistical modeling to understand the nature of and reasons for behavior. To inform practice and policy, we study (a) norms, values, and institutions, (b) cognitive, social, and policy processes, and (c) individual and group dynamics.
