Punishment:Punishment is an aversive consequence that decreases the likelihood of a behavior happening again. It involves applying or removing something unpleasant in response to the behavior.
Negative Reinforcement:Negative reinforcement refers to removing an undesirable stimulus after a behavior occurs, which increases the likelihood of that behavior being repeated.
Extinction:Extinction happens when a previously reinforced behavior is no longer followed by any kind of consequence, leading to a decrease in the frequency of that behavior.
