Which of the following is NOT one of the types of differential reinforcement?

Differential reinforcement is a behavior modification strategy that involves reinforcing a specific behavior while withholding reinforcement for other behaviors. The options listed represent different methods of differential reinforcement, while the one identified as the correct answer, DPB, does not correspond to a recognized type in this context.

DRA stands for Differential Reinforcement of Alternative behavior. This involves reinforcing an alternative behavior that serves the same function as the undesired behavior, encouraging positive behavior change.

DRI refers to Differential Reinforcement of Incompatible behavior. This method reinforces a behavior that is incompatible with the undesired behavior, meaning that the individual cannot engage in both behaviors at the same time.

DRO, or Differential Reinforcement of Other behavior, focuses on reinforcing when the undesired behavior does not occur during a specified time. This approach aims to reduce the frequency of specific behaviors by rewarding the absence of those behaviors.

Since DPB does not represent an established method of differential reinforcement, it is correctly identified as not fitting into the types of differential reinforcement typically discussed in the field of communication disorders.
