Dr. Chapman’s research goal is to illuminate the psychological processes underlying decision making and to harness these findings in the design of theoretically-motivated, policy-relevant interventions to facilitate healthy and prosocial behavior such as vaccination and blood donation.  Her research combines the fields of judgment and decision making and health psychology.  Using both laboratory and field experiments, she tests behavioral interventions, simultaneously exploring the theoretical mechanisms of decision making and also yielding policy insights into methods for improving health behavior and health outcomes.
