Which statement correctly describes the relationship between reinforcement and punishment?

• A. Reinforcement increases behavior, punishment decreases behavior.
• B. Reinforcement decreases behavior, punishment increases behavior.
• C. Both reinforcement and punishment increase behavior.
• D. Both reinforcement and punishment decrease behavior.

Answer: (A)

Reinforcement makes a behavior more likely to occur again, while punishment makes a behavior less likely to occur again. A reinforcement outcome either presents something desirable or removes something aversive, which strengthens the behavior. Punishment introduces an aversive consequence or removes a valued stimulus, which weakens the behavior.

So the statement that reinforcement increases behavior and punishment decreases behavior reflects the basic relationship between these two concepts. For example, giving praise or a treat after a correct response (reinforcement) increases the chance of that response happening again, while scolding or taking away a preferred toy after an undesired action (punishment) reduces the likelihood of that action in the future.

The other possibilities would imply both processes do the same thing, which isn’t how reinforcement and punishment function in learning.
