★ The Verdict

Intermittent and variable reinforcement protect behavior during extinction, but rich alternative reinforcers can later fuel resurgence, so thin them gradually.

✓ Read this if BCBAs who use extinction or DRA with any population.
✗ Skip if Practitioners who only run skill-acquisition programs without problem behavior.

01Research in Context

01

What this study did

Smith (1996) wrote a short commentary. It praised a review about why behavior keeps going during extinction. The author urged researchers to test the variables that review listed.

The paper did not run new experiments. It simply endorsed the earlier review and asked the field to study intermittent, delayed, and variable reinforcement schedules.

02

What they found

The commentary found no new data. It stated that future work should check how different reinforcement schedules affect resistance to extinction.

The clear message: use mixed, late, or unpredictable reinforcement if you want behavior to survive periods when reinforcement stops.

03

How this fits with other research

Podlesnik et al. (2023) and King et al. (2024) now supersede the 1996 call. Both teams ran full systematic reviews of extinction and resurgence studies. They mapped fifty years of data and showed exactly which procedures change relapse risk.

Jaffe et al. (2002) extends the idea. They tested children with autism and found that switching to continuous reinforcement right before extinction can slightly speed up the drop in problem behavior. This gives clinicians a first real data set on the topic the commentary wanted explored.

Johnston et al. (2017) adds a twist that looks like a contradiction but is not. They showed that rich alternative reinforcement knocks target behavior down fastest, yet it also creates the biggest resurgence when it stops. The 1996 piece never warned about this rebound; it only said rich schedules help behavior survive extinction. The newer study clarifies that survival is a double-edged sword.

04

Why it matters

You can finally move beyond the 1996 advice. Use intermittent or variable schedules when you need durability, but plan for resurgence if you later remove rich alternative reinforcers. Start thinning those alternatives early and track data longer than you think you need. These updates turn a twenty-five-year-old plea into a concrete, risk-managed protocol you can apply with any client next week.

03Original abstract

Lerman and Iwata's article represents a departure from typical JABA publication practices.First, it is a review and discussion article, and second, it is quite lengthy.However, it serves as a model for a type of article that is needed in the field of applied behavior analysis.It presents a comprehensive, well-organized review of basic and applied research on a major topic in behavior analysis.It analyzes the literature on that topic in a critical yet even-handed manner.It notes where there is a lack of information and suggests specific research.Finally, there are suggestions based on the review and analysis that, if followed, should lead to improved behavioral treatment.One reviewer of Lerman and Iwata's article wrote, ''This is a comprehensive and well-organized review that will guide applied research for years to come.''It is precisely because it is likely to have a powerful effect on future research and clinical practice that it should receive critical attention.The article reviews the variables applied during acquisition and maintenance that increase resistance to extinction.Some of these are intermittent reinforcement, delay in reinforcement, and variable stimulus conditions.Conversely, continuous reinforcement, immediate reinforcement, and constant stimulus conditions are associated with less resistance to extinction.In general, the experimental literature on these variables is consistent.The authors suggest that, if one seeks to produce durable behavior that will persist during periods of nonreinforcement,
