Jeremy continues to ask his manager, Caitlyn the same questions over and over again. Caitlyn decides to simply ignore Jeremy and does not answer his questions. Caitlyn is using the behavior modification approach known as extinction.

Extinction is the behavior modification approach that involves withholding reinforcement for a behavior, which leads to a decrease in that behavior over time. In this case, Caitlyn is ignoring Jeremy's repeated questions, which is a form of withholding reinforcement, and this should lead to a decrease in the behavior.
