My research has focused on applications of theoretical psychology to the alleviation of social problems in the United States and abroad. My basic research addresses decision making, attitude formation, attitude change, and how attitudes and cognitions influence behavior. This includes analysis of explicit attitudes and cognitions, implicit attitudes and cognitions, and affect-based emotions as determinants of behavior.
On an applied level, I conduct rearch on adolescent problem behaviors related to unintended pregnancy and substance use. I have been developing programs for parents of adolescents to teach parents how to more effectively communicate and parent their children so as to reduce the risk of unintended pregnancies and problems due to substance use. The approaches rely heavily on communication theory, decision theory, and attitude theory.
I also have a program of research on statistical methods, primarily on the analysis of interaction effects. I am developing a general framework for statistical analysis that eschews p values and focuses instead on magnitude estimation and margins of error.
Finally, I have also written about theory construction and how to construct theories. I just finished a book with Jacob Jacoby that gives scientists practical, hands-on approaches to getting ideas and translating them into coherent theories.
