Escape Extinction in ABA: What It Is and the Debate

Escape extinction is a procedure used with escape-driven behavior. Some behavior works to get out of a task or a demand. With escape extinction, that escape is no longer allowed. The task stays in place even after the problem behavior.

The idea is simple, but the use is not. Escape extinction can reduce behavior, yet it carries real risks. It can bring out more distress before things get better. Today many clinicians debate when, or even whether, to use it. This guide walks through both sides.

What escape extinction is#

To understand escape extinction, start with escape. If a child hits and the task goes away, escape is the reward. Over time, the hitting keeps working because it earns a break.

Escape extinction breaks that link. The break no longer follows the behavior. In feeding work, this can look like keeping the spoon in place. The person cannot escape the bite by acting out.

Because the escape is blocked, behavior can spike at first. This early rise is common when extinction begins. It can include more crying, pushing, or aggression. This spike is one reason the procedure draws so much debate. It asks a lot of both the learner and the staff.

The fidelity or function question#

Matthew Harrington uses a case to show a common trap. A school client was on an escape extinction plan. But the aggression was getting worse, not better.

The current behavior intervention plan is escape extinction, and the behavior was escalating prior to you coming onto the case. From the talk. Matthew Harrington

Rising behavior is a clue, not a dead end. It points to two possible problems. Either the plan is not run correctly, or the function is wrong.

So looking at our example, the behavioral principles at play, we have escape extinction is in place, but behavior is escalating. We can assume if behavior is escalating that either escape extinction isn't being applied with fidelity, which is possible if we have severe aggression, or the behavior isn't maintained by escape. From the talk. Matthew Harrington

Fidelity means the plan is run the same way every time. If staff give in during severe aggression, escape sneaks back. That accidental escape can make the behavior stronger. So the first check is whether the plan is even in place as written.

The second check is function. Maybe the behavior is not about escape at all. If it seeks attention instead, escape extinction will not help. Harrington walks through this kind of diagnosis in Solving Clinical Challenges with Research.

Why some clinicians avoid it in feeding#

Dr. Holly Gover comes at this from feeding research. Her lab set out to build other options. They wanted methods that did not lean on escape extinction.

We really felt like we needed to be publishing on alternatives to escape extinction. And so I think that was really the impetus for it. From the talk — Dr. Holly Gover

Her worry is the risk to the child. Forcing bites can create a scary history around food. That history can outlast the treatment itself.

I would say that if the child is food selective, I would never use escape extinction. I'm saying that now. From the talk — Dr. Holly Gover

Gover is clear that this is her line to draw. She does not work in settings that use it. Still, she is careful not to throw out the whole technology for everyone.

Alternatives to escape extinction#

The field has worked hard to find gentler paths. Many focus on the setup before the bite. They change what happens first so the child stays calm.

One approach uses differential reinforcement. The child earns a strong reward for eating or cooperating. Another slowly fades a hard step, such as the distance of the spoon. These methods aim to build skill without forcing escape.

A key part of these plans is trust. The team wants the child to feel safe with the task. A safe start makes the child more willing to try. That willingness can do work that force cannot.

When teams still consider it#

Escape extinction is not banned across the field. Some teams keep it as an option for severe cases. This is most true when safety is at risk right now.

The choice depends on the behavior and the setting. A behavior that causes serious harm changes the math. So does a setting with strong staff training and oversight.

Even then, most teams add safeguards. They confirm the function first with a good assessment. They train staff to run the plan the same way each time. They pair it with rewards for the right behavior. And they watch closely for signs of distress.

What the research says#

Research shows escape extinction can work, but it comes with concerns. One review gathered 21 feeding studies that skipped escape extinction. It found antecedent and reinforcement methods that raised food acceptance without it (Tereshko, Leaf, Weiss, Rich, & Pistorino, 2021).

Other studies show you can reach hard goals without escape extinction. In one study, differential reinforcement plus slow stimulus fading helped children with autism cooperate with nasal swab tests. All five kept cooperating at follow-up (Briere, Janetzke, Fleck, & Bourret, 2025). Another study tested a "wait out" method as a reactive option. It cut problem behavior and raised compliance with non-preferred tasks (Ward, Parker, & Perdikaris, 2016).

There are cases where escape extinction has helped. One study paired it with protective equipment for severe self-injury. Head hitting dropped, and gains held at an 18-month follow-up (Tereshko & Sottolano, 2017). The takeaway is that both risk and benefit are real, so the choice depends on the case.

FAQ#

What is escape extinction in simple terms?

Escape extinction stops a behavior from earning a break. If a child acts out to avoid a task, the task no longer goes away. The break that once rewarded the behavior is removed. Over time the behavior often drops.

Is escape extinction still used in ABA?

Yes, but it is heavily debated. Some clinicians use it for severe, escape-driven behavior with strong safeguards. Others avoid it, especially in feeding, over concern about creating fear. The field is building more alternatives that do not rely on it.

Why does behavior sometimes get worse with escape extinction?

Two reasons are common. The plan may not be run the same way each time, so escape sneaks back. Or the behavior may not be about escape at all. In that case the plan targets the wrong cause.
