What is the term for the method in Behavior Modification where reinforcement is discontinued to stop a behavior?

In the realm of behavior modification, extinction refers to the process where a previously reinforced behavior decreases in frequency and eventually stops because the reinforcement maintaining it is no longer provided. The core principle is that if a behavior is no longer followed by a desirable consequence, it loses its purpose and is less likely to be repeated. For example, if a child whines for attention and the parent consistently stops giving attention when the child whines, the whining behavior is likely to decrease over time. It's crucial to understand that extinction is not punishment; rather, it involves the removal of a positive reinforcer. Initially, an "extinction burst" might occur, where the behavior temporarily increases in intensity or frequency as the individual tries harder to elicit the accustomed reinforcement. However, with consistent application, the behavior will diminish, making extinction a powerful tool for eliminating undesirable behaviors.
