The effects of delivering nondrug alternative reinforcement on resistance to extinction and reinstatement of rats' ethanol‐maintained lever pressing were evaluated in two experiments. In both, rats self‐administered ethanol by lever pressing in a two‐component multiple schedule during baseline. In the Rich component, alternative food reinforcement was made available for performing an alternative response (Experiment 1) or according to a differential‐reinforcement‐of‐other‐behavior schedule for lever pressing (Experiment 2). In the Lean component, only ethanol was available. Moreover, the frequency of alternative reinforcement was manipulated across conditions in Experiment 1. Following baseline, lever pressing was extinguished in both components by suspending ethanol reinforcement, and alternative food reinforcers were discontinued. Finally, to test for reinstatement, ethanol reinforcers were delivered independently of lever pressing in both components. In both experiments, proportion‐of‐baseline response rates were higher during extinction and reinstatement testing in the Rich component than in the Lean component (although differentiation was not observed at the lowest frequency of alternative reinforcement in Experiment 1). Thus, alternative nondrug reinforcers increased resistance to extinction and reinstatement of rats' ethanol‐maintained lever pressing, even when those reinforcers were delivered contingently on an alternative response or on abstinence from lever pressing.
