Which type of differential reinforcement places other behaviors on extinction?

The correct answer is Differential Reinforcement of Other Behaviors. This type of differential reinforcement involves reinforcing a person for engaging in any behavior other than the undesired behavior. By doing so, it places the undesired behavior on extinction since it is no longer reinforced, thus reducing its occurrence over time.

This approach focuses on providing positive reinforcement when the individual is not exhibiting the behavior to be decreased, effectively decreasing that behavior by withholding rewards for it. This strategy relies on the natural occurrence of other behaviors, ensuring that the individual has reinforcement for alternate actions.

Differential Reinforcement of Alternate Behaviors and Differential Reinforcement of Incompatible Behaviors do not involve placing other behaviors on extinction; rather, they reinforce specific alternative behaviors that serve as replacements for the undesired behavior. In the context of this question, while all forms of differential reinforcement aim to shape behavior in a positive way, only Differential Reinforcement of Other Behaviors specifically utilizes extinction for the target behavior.
