What happens when a behavior is reinforced by taking away something negative?

When a behavior is reinforced by taking away something negative, it is referred to as negative reinforcement. This process involves the removal of an unpleasant stimulus following a desired behavior, which increases the likelihood of that behavior occurring again in the future. For example, if a student studies hard to avoid the stress and anxiety of failing an exam, the removal of that anxiety serves as a reinforcer for the studying behavior.

Negative reinforcement differs fundamentally from punishment and positive reinforcement. Punishment introduces an unpleasant consequence to reduce behavior, while positive reinforcement adds a pleasant stimulus to increase a behavior. Thus, negative reinforcement specifically involves the elimination of a negative condition, making it a key concept in understanding how behaviors can be encouraged through the removal of adverse stimuli.
