Definition
An extinction burst is a temporary intensification of a behavior when its usual reinforcer is removed. It is a normal, predictable feature of behavior change — not evidence that the change is failing.
Why it matters
Knowing extinction bursts exist prevents caregivers and self-changers from giving up right before change consolidates.
The Science
Extinction bursts are documented across species and behaviors. They typically peak briefly and then decline if reinforcement remains withheld.
The NSI Perspective
NSI treats extinction bursts as a sign that the pattern is loosening, not that intervention is failing.
Clinical Implications
Preparing patients and families for extinction bursts improves adherence to behavioral plans.
Practical Application
When a new plan gets harder before it gets easier, that may not be failure. It may be exactly the moment change happens if you stay steady.
