Extinguish unwanted behaviors by removing their reinforcement
Stop a behavior by consistently withholding the reinforcer that maintains it — not by punishing it.
Why it works
Extinction works by breaking the contingency between a behavior and its maintaining reinforcer. Without reinforcement, the behavior loses its functional purpose and decreases over time. This is preferable to punishment because it does not generate emotional side effects (aggression, avoidance, anxiety) associated with aversive control. The key is identifying the actual reinforcer, which is often not the obvious one.
How to do it
- Identify what consequence is actually maintaining the unwanted behavior (attention, relief from discomfort, access to a reward).
- Consistently withhold that reinforcer after every occurrence — partial delivery restores the behavior.
- Expect an extinction burst: behavior often increases temporarily before decreasing. This is normal and will pass.
- Simultaneously reinforce an alternative behavior that serves the same function.
Evidence
Extinction as a behavioral procedure is well established in operant theory and applied behavior analysis. Extinction bursts (temporary behavior increase) are a real but not universal finding — Lerman and Iwata documented bursts (and extinction-related aggression) in only a minority of treated cases, so a burst should be anticipated but not assumed inevitable. (clinical)
Pure extinction without differential reinforcement of an alternative is less effective and more frustrating than extinction plus DRA. Spontaneous recovery (return of the behavior) can occur after apparent extinction.

Common mistake
Inconsistent withholding — occasionally delivering the reinforcer during extinction produces a variable-ratio effect and makes the behavior even more resistant to removal.

More practices for Operant Conditioning and Schedules of Reinforcement
- Design a genuine positive reinforcer for the target behavior
Identify something that genuinely increases your likelihood of repeating the behavior — not what should work, but what actually does.
- Use variable-ratio reinforcement to make habits persistent
Once a behavior is established, shift to an unpredictable reward schedule to make it resistant to extinction.
- Shape complex behaviors through successive approximations
Reinforce progressively closer approximations to the target behavior rather than waiting for the full behavior to appear.
- Use differential reinforcement to increase desired behavior while reducing unwanted behavior
Reinforce the behavior you want while withholding reinforcement from the one you don’t — at the same time.
- Make consequences immediate to bridge the reward delay problem
The closer in time a consequence follows a behavior, the stronger its effect on that behavior.
- Modify antecedents to trigger behavior before it depends on motivation
Change the cues that precede a behavior to make it more or less likely to occur.
