What is the initial temporary increase in the targeted behavior after implementing extinction called?

The initial temporary increase in the targeted behavior after implementing extinction is referred to as an extinction burst. When extinction procedures are applied, individuals may initially respond with an increase in the frequency, intensity, or variability of the behavior that is being targeted for reduction. This phenomenon occurs because the individual is attempting to elicit a response or outcome that was previously associated with the behavior. The persistence can be seen as a test of the new conditions where the reinforcer is no longer available.

Understanding the extinction burst is crucial for practitioners, as it underscores the importance of consistency and patience when implementing behavioral interventions. Recognizing this phase allows behavior analysts and practitioners to prepare for the increased behavior and to maintain their commitment to the extinction process, ensuring that the behavior ultimately decreases over time.

The other terms like behavioral ambiguity, behavior escalation, and behavior rebound are not typically used to describe this initial increase seen with the implementation of extinction. Behavioral ambiguity refers to a lack of clarity in the behavior, while behavior escalation generally indicates a worsening of the behavior rather than a temporary increase. Behavior rebound might suggest a resurgence of the unwanted behavior after an intervention has ended but does not specifically capture the initial response seen during extinction.
