What is the term for the initial increase in behavior that may occur when using extinction?

The initial increase in behavior that may occur when using extinction is referred to as "Extinction Bursts." This phenomenon occurs when a behavior that was previously reinforced temporarily increases in frequency, intensity, or duration before it begins to decrease. During the extinction process, the individual may engage in the behavior more vigorously, which is often a response to the removal of reinforcement. This increase can be a sign that the individual is attempting to regain the lost reinforcement, indicating that they are struggling to adjust to the new conditions. Recognizing extinction bursts is crucial for practitioners, as they need to remain consistent in implementing procedures, ensuring that they do not reinforce the behavior again during this phase, which can undermine the extinction process. Understanding this concept helps practitioners effectively manage behaviors during treatment.
