The term "negative reinforcement" is used to describe a particular type of behavior modification technique that involves the removal of an undesired stimulus in order to increase the likelihood of a desired behavior. However, there are several other terms that are often used interchangeably with this phrase, including "escape conditioning", "aversive control", and "punishment by removal". These phrases essentially describe the same basic concept of using negative stimuli to increase the likelihood of a certain behavior, but may be preferred by different scholars or in different contexts. Ultimately, regardless of the phrasing, the goal of negative reinforcement is to motivate organisms to engage in certain behaviors by removing an unwanted influence from their environment.
