The purpose of this study was to determine if a variable, non-contingent reinforcement, could account for a significant amount of the effect of psychotherapy. A sample of ninety subjects was drawn from basic psychology classes and randomly assigned to six groups in a variation of the Soloman 4-group design. The treatment groups were connected to sham GSR equipment and told that when a light flashed they had made an anxiety reducing statement and were becoming more mentally healthy. The subjects were given three by five cards upon which were typed positive-negative adjective pairs and told to use the cards as …

In two experiments pigeons were exposed to VI and FI schedules and schedules approximating both VI and FI schedules. In experiment I, the probabilities of the VI and FI components in a Mixed FI VI schedule were manipulated to create schedule contingencies approximating simple VI or FI. In experiment II, the minimum and maximum inter-reinforcement intervals were manipulated to create schedule contingencies approximating simple VI or FI. The major finding of both of these experiments was that maximal control by the dimension of time occurred as FI contingencies were approximated. Control by any one temporal value in experiment I depended …
