Ellen Peters

Dr. Peters is a Distinguished Professor of Psychology at The Ohio State University. She conducts basic and applied research in judgment and decision making. In her research, Dr. Peters focuses on understanding the basic building blocks of human judgment and decision making and especially how affective, intuitive, and deliberative processes help people to make decisions in an increasingly complex world. She studies decision making as an interaction of characteristics of the decision situation and characteristics of the individual and is particularly interested in issues of number processing, affect and emotion, and adult aging in judgment and decision making.

Much of his research is focused around differentiating sources of information (learning about probabilities through experience as opposed to description), the subjective values of the differing sources and how the information is processed intuitively and deliberately. In addition he is also interested in repeated decisions, economic decision models, behavioral game theory, and probabilistic inference. Dan has since received his Ph.D. from The Ohio State Univerisy and is currently working at Erasmus Univeristy.
