Reinforcement increases behavior likelihood, punishment decreases it.
Reinforcement, either positive or negative, works by increasing the likelihood of a behavior. Punishment, on the other hand, refers to any event that weakens or reduces the likelihood of a behavior.
Positive reinforcement involves presenting something favorable after a response, while negative reinforcement involves removing something unpleasant. Positive punishment introduces an undesirable stimulus to reduce behavior, and negative punishment removes a pleasant stimulus for the same purpose.
