Reinforcement: Reinforcement is a term used in operant conditioning to describe the process of increasing the likelihood of a behavior occurring again by providing a reward or removing an unpleasant stimulus.
Punishment: Punishment refers to the addition of an aversive stimulus or removal of something positive to decrease the likelihood of a behavior repeating itself.
Extinction: Extinction occurs when a previously reinforced behavior no longer receives reinforcement, leading to a decrease in its frequency and eventual disappearance.
