What does DRH stand for in behavioral reinforcement?

The term "DRH" stands for Differential Reinforcement of Higher rates of behavior. This concept is rooted in behavior modification, specifically within the framework of Applied Behavior Analysis (ABA). DRH is a strategy used to encourage an increase in desired behaviors by providing reinforcement contingent upon achieving higher frequencies of those behaviors within a specified period.

For instance, if a teacher wants to promote more frequent participation in class, they might use a DRH strategy by only offering praise or rewards when a student raises their hand to answer questions a certain number of times during a lesson. This method helps to shape and enhance the behavior rather than simply reinforcing it when it occurs at any level.

This approach contrasts with other potential definitions that might include reinforcement of habitual or historical behaviors, which do not focus specifically on increasing the frequency of a behavior but rather on maintaining existing behaviors or addressing various types of responses. Therefore, the focus of DRH is precisely on elevating the occurrence of specific behaviors, making it a critical tool in behavior management and modification within educational and therapeutic settings.
