TL;DR: Although FCT often resulted in quick reductions in destructive behavior and increases in appropriate behavior, destructive behavior often recurred during the extinction probes conducted during the initial treatment, consistent with the quantitative predictions of behavioral momentum theory.

TL;DR: Suggestions that smoking-produced sensory stimuli may function as conditioned reinforcers and that the relative reinforcing efficacy of cigarettes is determined by the combined effects of the nicotine/conditioned reinforcing complex provided by smoking are supported.

TL;DR: Three experiments examining whether the rate of reinforcement in the presence of a stimulus similarly modulates the relative relapse of operant behavior produced by reinstatement, resurgence, and renewal paradigms suggest that a model of extinction from behavioral momentum theory may be useful for understanding results.

TL;DR: A quantitative model of resurgence based on the augmented model of extinction provided by behavioral momentum theory suggests that alternative reinforcement during extinction of a target response acts as both an additional source of disruption during extinction and as a source of reinforcement in the context that increases the future strength of the target response.

TL;DR: The theory provides a framework within which to consider the effects of interventions such as extinction, noncontingent reinforcement, differential reinforcement of alternative behavior, and other phenomena (e.g., resurgence).
