What would be a practical application of DRL?

The choice of a child receiving a reward for asking fewer than 3 questions during the lesson is a practical application of Differential Reinforcement of Low Rates of Responding (DRL). This approach specifically aims to reduce the frequency of a particular behavior while still reinforcing it when it occurs at a lower, more acceptable rate. In this scenario, the focus is on decreasing the number of questions asked to a manageable level without completely eliminating the behavior.

By setting a specific goal for the child, such as asking fewer than 3 questions, this method encourages them to participate in classroom discussions but discourages excessive questioning that may disrupt the learning process. The reward serves as a positive reinforcement for achieving this goal, illustrating how DRL can effectively modify behavior while still maintaining an acceptable level of engagement.
