DRH is used when a behavior is already occurring but needs to happen more frequently.
Example:
A teacher wants a student to participate more during class discussions. Currently, the student raises their hand 1-2 times per class. The teacher sets a target of 4 hand-raises per class period and provides reinforcement (e.g., praise or tokens) only when the student raises their hand at least 4 times. Over time, the reinforcement encourages the student to engage in the behavior more frequently.
