In both cases, the frequency of a given behaviour is strengthened. For negative reinforcement, the behaviour that is strengthened is the one that helps the person avoid an unpleasant consequence. Therefore, when you are negatively reinforced you have successfully avoided an unpleasant consequence. In extinction a pleasant consequence is removed or a neutral consequence occurs. This has the effect of weakening a behaviour.
Punishment occurs when an unpleasant consequence is presented.
Punishment and extinction both weaken behaviour. Behaviour can be linked to its consequences in four ways. Each of these relationships is called a contingency of reinforcement.
