Negative reinforcement is a concept in psychology that involves the removal of an unpleasant stimulus to increase a desired behavior. For example, if a student studies hard to avoid getting a bad grade, the removal of the anxiety about failing acts as a negative reinforcer. This encourages the student to continue studying in the future. In everyday life, negative reinforcement can be seen when a person takes pain relievers to eliminate a headache. The relief from pain reinforces the behavior of taking medication, making it more likely that they will do so again when they experience discomfort. This process helps shape behaviors by removing negative experiences.
