Dr. Wedell received his Ph.D. in Cognitive Psychology from the University of California
at Los Angeles in 1984. After positions as a Research Associate at UCLA, Post Doctoral Fellow in Quantitative
Psychology and Visiting Assistant Professor at the University of Illinois, he joined the faculty at the
University of South Carolina in 1989. He has been funded by the National Science Foundation in grants to
study how people evaluate of probabilistic alternatives, how process tracing can be used to understand choice and
judgment, and how contextual dependence may lead to invalid assessments.
