Which of these behavioral approaches focuses on rewarding appropriate behavior?

The choice of differential reinforcement prominently emphasizes the concept of rewarding desired behaviors while simultaneously reducing or eliminating inappropriate behaviors. This approach involves reinforcing a specific behavior while withholding reinforcement for undesired behaviors, thereby increasing the likelihood that the individual will continue to perform the desired behavior.

Differential reinforcement can take several forms, such as reinforcing a behavior more frequently than undesired behaviors, or utilizing reinforcement for appropriate actions in different contexts. This approach is particularly effective in modification of behavior since it focuses on positively reinforcing good behavior, which enhances motivation and encourages consistency in performance.

While other approaches listed also involve some form of reinforcement, differential reinforcement specifically delineates the process of encouraging appropriate behaviors through strategic rewards, making it distinctly applicable in contexts requiring behavior modification.
