noncontingent reinforcement

the process or circumstances in which a stimulus known to be effective as a reinforcer is presented independently of any particular behavior. Because contingencies may arise by accident (see accidental reinforcement), behavior-independent presentation of stimuli cannot guarantee that no contingency exists between a response and the stimuli. See reinforcement.
