Preventing Relapse of Problem Behavior Through Behavioral Economics: A Translational Analysis

"Progressive ratio training (PRT) is used to prevent recurrence of the proxy response when extinction errors occur. PRT involves providing a reinforcer for the proxy response on a geometric progressive ratio (PR) scale. The schedule requirement will increase for the target response each time a reinforcer is delivered. For example, once a reinforcer is delivered on the PR-2 schedule, the requirement will increase to a PR-4, then to a PR-8, -16,~-32, etc."

In DRA with extinction, the proxy for problem behavior is placed on extinction and no longer produces reinforcement. The proxy for communication behavior produces reinforcement on a fixed-ratio 1 schedule of reinforcement.
