Per Holth

Professor Per Holth received his license to practice psychology in 1983, and his Ph.D. in 2000, with a dissertation on the generality of stimulus equivalence. His clinical work has been in services for people with autism and developmental disabilities, in psychiatric units, and in the military services. His research activities span basic research, on stimulus equivalence and joint attention, as well as applied work and management of large research projects. Per Holth has taught classes in behavior analysis and learning principles at the University of Oslo and Oslo and at OsloMet—Oslo Metropolitan University since 1982 and joined the faculty of OsloMet and the Program for learning in complex systems, as an associate professor in 2004 and as full professor in 2006. He teaches classes in all behavior-analytic education programs at OsloMet. He has written for peer-reviewed publications on basic research, applied work, and philosophy of science, served on several editorial boards, and he was one of the founding Editors and a member of the editorial troika of the European Journal of Behavior Analysis for 15 years, and is currently an associate editor of Perspective on Behavior Science. He was on the board of directors of the B.F. Skinner Foundation from 2012 to 2019. He has been a program co-coordinator of the TPC area and for the Development area of ABAI, and he has been the international representative at the ABAI Council from 2017 to 2020. His current research interests have drifted in the direction of basic experimental work with animals and humans, specifically concerning (1) sources of behavioral variability, (2) blocking and the establishment of conditioned reinforcers, (3) delay of reinforcement, (4) multiple exemplar training, such as in the establishment of naming and continuous repertoires, and (5) variables affecting confirmation bias. However, he also maintains an interest in theoretical, conceptual, and philosophical issues, including verbal behavior, radical behaviorism, and different types of explanations.
