Final answer:
Differential Reinforcement of Diminishing Rates (DRD) is a behavioral technique used to decrease the frequency of an undesired behavior by reinforcing the individual when they show less of that behavior.
Step-by-step explanation:
Differential Reinforcement of Diminishing Rates (DRD) is a behavioral modification technique used in psychology. DRD involves reinforcing an individual only when they exhibit a lower rate of a particular behavior than they did previously. The goal is to decrease the frequency of an undesired behavior over time. An example could include reinforcing a student for raising their hand fewer than five times during class if they typically raise their hand excessively. The reinforcement can be any type of reward or positive consequence that increases the likelihood of the desired behavioral change. As the behavior diminishes to an acceptable rate, the criteria for reinforcement may also be adjusted to maintain continued progress.
