Relation between behavior and its consequences. When behaviors are strengthened by consequences, we can also say they are conditioned or increased in future probability. When behaviors are weakened by consequences, we can also say they are suppressed or decreased in future probability.
Every response is followed by a reinforcing event.
Behavioral rates within a specified range are reinforced. Reinforcement is delivered periodically not contingent on a specific behavior. The spread of the effects of learning to appropriate new instances and new settings. The concentration of the effects of learning to stimuli and responses within specified parameters. The reduction of a behavior as a result of the removal of reinforcing consequences.
