Behavior strengthened by reinforcement: acts on the environment to produce a consequence and, in turn, is controlled by, or occurs again in the future as a result of its immediate consequence reinforcer. The consequence that strengthens the operant behavior. Positive and negative reinforcement both positive and negative reinforcement strengthen a behavior: they are distinguished by the nature of the consequence positive reinforcement. The occurrence of a behavior is followed by the addition of a stimulus (a positive reinforcer) or an increase in the intensity of the stimulus, which results in strengthening of the behavior negative reinforcement. The occurrence of a behavior is followed by the removal of a stimulus (an aversive stimulus) or an decrease in the intensity of the stimulus, which results in strengthening of the behavior stimulus. When behavior produces a consequence through the actions of another person: automatic reinforcement. When behavior produces a consequence through direct contact to the physical environment: premack principle.
