Negative reinforcement occurs when the rate of a behavior is observed toincrease following the removal of a stimuli. In other words, the terminationor removal of an aversive stimulus is likely to increase the target behavior.

Both positve and negativereinforcements strengthen the associated behavior.

It is important to remember that negative reinforcement is not the same as punishment, with which it is often confused.
