Which statement best distinguishes positive reinforcement from punishment?

• A. Positive reinforcement reinforces undesired behavior with consequences.
• B. Positive reinforcement encourages desired behavior with rewards; punishment applies aversive consequences to discourage undesired behavior.
• C. Punishment is always the removal of privileges.
• D. Both approaches are identical.

Answer: (B)

The main idea here is how consequences shape behavior. Positive reinforcement increases the likelihood of a behavior by adding something desirable after the behavior, essentially rewarding what you want to happen. Punishment decreases a behavior by presenting something aversive or by taking away something desirable. The statement that best captures this distinction says that positive reinforcement uses rewards to encourage the desired behavior, while punishment uses aversive consequences to discourage the undesired behavior. The other options don’t fit: adding consequences to undesired behavior wouldn’t be reinforcement, punishment isn’t limited to removing privileges (that’s only one form, called negative punishment), and the two approaches are not identical.
