Resurgence and repeated within‐session progressive‐interval thinning of alternative reinforcement

A Quantitative Analysis of Response Elimination and Resurgence Using Rich, Lean, and Thinning Schedules of Alternative Reinforcement

An alternative method of thinning reinforcer delivery during differential reinforcement.

Differential reinforcement of alternative behavior (DRA) may result in rates of reinforcement that are impractical for caregivers to implement; therefore, recent research has examined methods for thinning reinforcer delivery during DRA. In this study, reinforcer delivery was thinned during DRA by restricting access to the participant's alternative response materials.

Effects of differential rates of alternative reinforcement on resurgence of human behavior.

Despite the success of exposure-based psychotherapies in anxiety treatment, relapse remains problematic. Resurgence, the return of previously eliminated behavior following the elimination of an alternative source of reinforcement, is a promising model of operant relapse. Nonhuman resurgence research has shown that higher rates of alternative reinforcement result in faster, more comprehensive su...

Effects of thinning the rate at which the alternative behavior is reinforced on resurgence of an extinguished instrumental response.

Three experiments with rats examined the effects of thinning the rate of reinforcement for the alternative behavior in the resurgence paradigm. In all experiments, pressing one lever (L1) was first reinforced and then extinguished while pressing a second alternative lever (L2) was then reinforced. When L2 responding was then extinguished, L1 responses "resurged." Resurgence was always observed ...

Repeated Inverse Reinforcement Learning

We introduce a novel repeated Inverse Reinforcement Learning problem: the agent has to act on behalf of a human in a sequence of tasks and wishes to minimize the number of tasks that it surprises the human by acting suboptimally with respect to how the human would have acted. Each time the human is surprised, the agent is provided a demonstration of the desired behavior by the human. We formali...
