Social Judgment & Behavioral Decision Making
Quantitative - Cognitive
My research focuses on understanding how people make decisions as well as on the factors that affect people's judgments. I am primarily interested in choice behavior (preferences). My work on choice behavior uses a stochastic model that I developed to investigate how individuals make trade-offs among characteristics of the options to be selected. For example, many products may be described in terms of their quality and their price. Because typically higher quality also implies higher price, the decision will not be an easy one. How do individuals resolve the conflict inherit in choosing? What affects the consistency of decision-making? How do people perceive changes in attribute values as a function of the context? How does persuasion affect the evaluation of objects to determine a final choice? Some of the basic notions in this research program are also applied to consumer and medical decision-making situations. Current research is also exploring money-time tradeoffs, attitude changes and models of information updating, nutritional judgments and health. I am also very interested in construct validity and philosophy of science more generally. This interest has led me to question the role of unconscious processing as defined and tested by current psychological research.
