Which statement correctly describes reinforcement vs punishment?

Which statement correctly describes reinforcement vs punishment?

• A. Reinforcement makes a behavior less likely; punishment increases it
• B. Reinforcement increases the likelihood of a behavior; punishment decreases it
• C. Both reinforcement and punishment increase behavior
• D. Neither affects behavior

Answer: (B)

Reinforcement strengthens a behavior by following it with a consequence that makes it more likely to happen again, while punishment weakens a behavior by following it with a consequence that makes it less likely to happen again. That’s why the statement that reinforcement increases the likelihood of a behavior and punishment decreases it is the best description. For example, giving a treat after sitting encourages the dog to sit again (reinforcement). Adding something unpleasant after barking discourages barking in the future (punishment). The other statements either reverse the effects or claim no change, which doesn’t fit how reinforcement and punishment work.
