Also referred to as unconditioned reinforcement, primary reinforcement is the process by which presentation of a stimulus following a response will increase the probability of a like response in the future. Such stimuli (the unconditioned primary reinforcer) is effective as reinforcement without any special training or experience.

PRIMARY REINFORCEMENT: "Reinforcing a response leads to the probability that the response will re-occur in the future."
