Mr. Duncan, who retired in 1987, served 40 continuous years as a member of the Northwestern faculty.
He joined the Northwestern faculty after receiving an undergraduate degree from the University of Maine and a doctoral degree from Brown University. His doctoral dissertation laid the groundwork for much of today's research into the physiology of memory.
Mr. Duncan was a member of the Society of Experimental Psychologists, a distinguished honorary society. He was a fellow of the American Psychological Association and a member of the American Psychological Society and the Midwestern Psychological Association. He served the latter group as president in 1965-66.
At Northwestern, Mr. Duncan directed the honors program in psychology for 35 years and also served as director of graduate studies. His research interests ranged from human learning to the physiology of clinical phenomena to problem solving and thinking.
A historian of psychology, Mr. Duncan served as the book review editor of the American Journal of Psychology. He edited all its reviews and wrote many reviews himself. Mr. Duncan received a fellowship from the National Science Foundation and served on NSF grant and fellowship panels.
Mr. Duncan is survived by his wife, Marie Duncan, M.D.
