The Changing Activity, Substance Use, and Health lab (CASHlab) is a research team in the Department of Psychology at James Madison University. The CASHlab is involved in a variety of research projects primarily focused on health choices and basic physiological and learning processes associated with substance use that may inform intervention. We are also interested in developing and testing behavioral interventions for health risk behaviors including substance use and inactivity.
Here is a list of some of our current and recent research topics:
Contingency Management for a variety of health behaviors (e.g., substance use, physical activity, smartphone use, and social media use)
Factors that affect relative reinforcing efficacy of substances, food, etc.
Effects of physiological states (e.g., drug priming, sleep deprivation) on health choices
Cue-induced withdrawal and its effects on health choices
Transactional Sex as a health risk behavior
Measurement validity related to health behavior
