Definitions:

Negative Reinforcement

The strengthening of a behavior because a negative condition is removed or avoided.

Punishing Reinforcement

A term that amalgamates concepts incorrectly; in behaviorism, punishment is used to decrease a behavior's occurrence, whereas reinforcement is used to increase it.

Positive Punishment

A technique in behavior modification that involves the introduction of an unfavorable outcome or event following an undesirable behavior, with the intention of decreasing the likelihood of the behavior occurring again.

Negative Punishment

A type of behavior modification that involves the removal of a desirable stimulus after a behavior to decrease the likelihood of that behavior occurring again.
