A Test of Reinforcer Forms with Flaps

Abstract

An experiment in which a new group, verbal-conditioning device (reinforcer form) was used was essentially replicated but with a modification of the reinforcer forms. The modification, involving paper flaps that conceal all symbols except those where S is working, was designed to make the experimental contingencies more analogous to the usual operant and respondent ones. Earlier results, showing the simultaneous operation of evaluative words as operant and respondent reinforcers, were confirmed.
