Extinction Burst
In Plain Language
A possible temporary increase in a behavior when its previous reinforcement stops.
ABA Definition
An initial increase in response frequency, intensity, or duration following discontinuation of reinforcement.
Everyday Example
You press a stuck elevator button repeatedly before stopping.
ABA Example
A clinician monitors for an early rise in responding when a previously maintaining consequence is discontinued.
How It May Be Used
Bursts are not inevitable and an increase does not prove extinction is working. New distress requires reassessment and attention to safety.
