Quizplus · Accepted Answer

Reinforcement refers to any consequence that increases the likelihood of a behavior being repeated in the future, while reward specifically refers to a pleasant or desirable consequence given as a result of a behavior. While rewards can be used as a type of reinforcement, not all reinforcement is a reward. For example, avoiding a negative consequence can also be a form of reinforcement.
