J. R. Kantor“Fields indicate that events consist of systems in which things or processes are in intimate relation with each other so that descriptions and explanations can be made without supernatural or transcendental powers, forces, and causes”(Kantor, 1984, p. 171)

For J. R. Kantor (1888-1984), psychology studies not just the person. Psychological events emerge from the interaction over time of several factors: individuals, environmental stimuli, setting factors, and media of contact (Kantor, 1959, pp. 15-16). Based on this conceptualization, Kantor developed a naturalistic viewpoint, interbehavioral psychology or interbehaviorism. Among his other contributions, Kantor co-founded a scholarly press, the Principia Press (1932), founded a journal, The Psychological Record (1937), and published twenty books and many articles. He earned his Ph.D. at the University of Chicago (1917) and served on the psychology faculty at Indiana University (1920-1959) (Mountjoy & Cone, 1997, 2006).

The purpose of this website is to serve as an educational resource for those with an interest in Kantor and interbehaviorism. See also William S. Verplanck’s website and Kantor page (on Verplanck’s life, see Burghardt, 2003).
