Roger T. Kelleher, behavior analyst.
Journal of the Experimental Analysis of Behavior, 86, 371-384.
Roger T. Kelleher, rightly known as one of the foremost contributors to
behavioral pharmacology, also made many important contributions to the
experimental analysis of behavior. He participated significantly in the
development of the discipline, through both his research and his editorial
contributions to this journal. This article summarizes his contributions
to the field of behavior analysis. His most significant empirical and
conceptual contributions to behavior
analysis came in two domains—conditioned reinforcement and the power of
schedules of reinforcement. His accomplishments in these two domains
still serve as principal foundations for modern research and theory.
Key words: Roger T. Kelleher, biography, conditioned reinforcement, reinforcement
