Three experiments were conducted comparing the effects of the relationship between the response-reinforcement interval and the reinforcement-reinforcement interval in a differential reinforcement of other behavior (DRO) contingency. The experiments followed an acquisition, treatment, and reacquisition sequence where rats were trained to press a lever for food, were exposed to response elimination contingencies (DRO and extinction), and finally tested for the effectiveness of their respective treatment conditions. Experiment 1 shows that the longer the response-reinforcement interval the more effective the suppressive effects of DRO. Experiment 2 shows that it is the relationship of the response-reinforcement interval to the reinforcement-reinforcement interval that is important for the effectiveness of DRO. Experiment 3 shows that the base schedule used during training can determine the durability of the treatment procedure used. Implications for the applied literature using DRO and extinction are discussed.
