Graphics for three-term contingencies

Abstract

A source of confusion in the general readership regarding the relationship of operant to S-R psychology is traced to the use of graphics in the behavioral literature. A case is made for supplementing traditional linear notation systems with triangular graphics to illustrate three-term contingencies. Constructing discriminative stimuli in this fashion makes the distinction between operant and S-R formulations more conspicuous and reveals more comprehensive relationships for an extended radical behaviorism.
