A review of investigations of operant renewal with human participants: Implications for theory and practice
Renewal is a real threat after extinction—program multiple contexts and gradual context fading to protect your treatment gains.
01Research in Context
What this study did
Saini et al. (2020) read every human study they could find on operant renewal. They wanted to see how often relapse happens when people return to the place where problem behavior first paid off.
The team pulled together lab work and clinical reports that used extinction plus a later context shift. They looked for patterns in how renewal shows up with real people, not just rats or pigeons.
What they found
Renewal hits people too. Across dozens of setups, behavior came back strong when the old setting returned.
Yet almost none of the studies tried to stop renewal. The review shows the effect is real; it also shows we rarely test fixes in clinically useful ways.
How this fits with other research
Jackson et al. (2026) picked up where the review left off. Their new RCT shows a simple move—fading the therapy room back in after DRA—cuts renewal in half. The 2020 review said "we need these studies"; Jackson delivered.
Falligant et al. (2024) add a warning. Their hospital charts show renewal strikes automatically maintained self-injury just as hard. Saini’s paper said the effect is robust; Falligant shows it even when behavior is sensory-based, not attention-based.
Nevin et al. (2016) seem to clash at first. They found lean signaled DRA keeps relapse low, while Saini stresses relapse after extinction. Look closer: Nevin tested relapse in the same room, Saini tested relapse after a room switch. Different processes, both worth watching.
Why it matters
You now have proof that renewal is not a lab toy—it happens in the clinic and the ward. Plan for it before you fade supports. Run sessions in several rooms, teach the client to notice context shifts, and fade the therapy setting back in slowly. These steps turn a robust relapse effect into a manageable bump.

03Original abstract
Operant renewal is the recurrence of a previously eliminated target behavior as a function of changing stimulus contexts. Renewal as a model of treatment relapse in humans suggests that a change in stimulus conditions or context is sufficient to produce relapse of a previously eliminated maladaptive behavior. The extent to which general findings from operant renewal studies involving nonhuman animal subjects are supported by relapse studies involving human participants is unknown. We conducted a systematic review of studies demonstrating or mitigating operant renewal in human participants in peer-reviewed studies found in PsycINFO, ERIC, PubMed, and Scopus between 1980 and 2019. We identified 12 studies involving 61 participants and 93 cases of operant renewal. We coded descriptive data on participant and study characteristics and calculated summary statistics. Results indicated that the renewal effect was a robust phenomenon, supported by demonstrations in both clinical and human-laboratory studies, and across a variety of variables and experimental preparations. However, there were relatively few studies involving human participants that attempted to reduce or eliminate renewal of clinically meaningful behavior. We discuss variables relevant for studying renewal in socially meaningful contexts, practical limitations of observing the renewal effect in real-world settings, implications for theoretical models of renewal, and identify barriers to methodology unique to human participants. We provide directions for future research related to implementing and translating nonhuman animal studies of renewal to applied settings.
