Current Research

Dr. Stock focuses her research on applying social-psychological theories to the study of risky health cognitions and behaviors, including substance use, sexual behaviors, and UV exposure. Her experimental and survey research focuses on the application of dual-processing models, in particular the Prototype-Willingness model (Gibbons, Gerrard, & Lane, 2003), to provide a framework for understanding the cognitive (both heuristic and reasoned) constructs and situational factors that affect health decisions. The research conducted in her lab can be split into three main areas:

1) the relation among risk behavior, social comparison, and perceptions of risk;

2) applying social psychological theory and the Prototype-Willingness model to health interventions;

3) examining the relation between racial discrimination and risky health cognitions and behaviors as well as risk and protective factors that may help explain and that may reduce this relation.
