Reed College


Dr. Timothy D. Hackenberg is professor of psychology at Reed College in Portland, Oregon. After receiving his Ph.D. from Temple University in 1988, he was a post-doctoral fellow at the University of Minnesota before joining the faculty at the University of Florida, where he taught from 1990 to 2009. Dr. Hackenberg's innovative and systematic comparative research of choice in human and nonhuman animals has led to new insights in the understanding of such general processes as foraging, gambling, self-control, and behavioral economics. His equally innovative analyses of token-conditioned reinforcement in animals has not only revived a long-dormant method for the analysis of conditioned reinforcement, but has led to important applications in behavioral economics and general decision theory. The result of this research is a large body of publications that are cited widely and valued by his peers. His research program has been supported by major grants from both the National Science Foundation and the National Institutes of Health (most recently by a $1 million NIH grant) and recognized by APA's Division 25, which bestowed on him its Distinguished Contributions to Basic Research Award. His research also has incorporated his 10 doctoral students, many of whom have gone on to teaching and research positions where they have in turn contributed to the further growth of behavior analysis. Dr. Hackenberg's students and colleagues comment not only on his contributions to basic research, but also on his creative, thoughtful teaching and scholarly contributions to the conceptual analysis of behaviorism and its role in contemporary psychology. Dr. Hackenberg has served psychology and behavior analysis in many roles, including as president of APA's Division 25, associate editor of the Journal of the Experimental Analysis of Behavior, on the board of directors of both the Society for the Quantitative Analyses of Behavior and the Society for the Experimental Analysis of Behavior, as a member of the executive council of ABAI, and as ABAI's Science Board coordinator.
