What is the goal of using DRL?

The goal of using Differential Reinforcement of Low Rates of responding (DRL) is to make a behavior occur less frequently. DRL is a behavioral strategy employed to decrease a specific behavior by reinforcing lower frequencies of that behavior. This approach encourages individuals to engage in the behavior less often while maintaining the behavior in a more manageable way.

In practical terms, if a child exhibits a behavior that occurs at an undesirable high frequency, implementing DRL allows for reinforcement when the behavior occurs at a lower frequency rather than aiming for complete cessation. This means that the individual can still engage in the behavior, but it is encouraged to occur less frequently, which is often more practical and achievable than trying to eliminate it entirely.

For instance, if a child frequently shouts answers in class, rather than trying to ensure they never shout out, a teacher might use DRL to reinforce moments when the child raises their hand or participates in a quieter manner. This approach not only reduces the frequency of the shouting but also acknowledges and supports appropriate behavior.
