Lab Members

Lab Director

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. She is a Fellow of the American Association for the Advancement of Science (AAAS), the American Psychological Association, the Association for Psychological Science, and the Society of Experimental Psychology.  For more information about Dr. Peters, visit her faculty page.
