Man's intention is thus important for the long-term "reward" of a good world. Reinforcement means you are increasing a behavior, and punishment means you are decreasing a behavior. Reinforcement can be positive or negative, and punishment can also be positive or negative. All reinforcers (positive or negative) increase the likelihood of a behavioral response.

At least four different types should be noted: (1) positive reinforcement; (2) avoidance learning, or negative reinforcement; (3) extinction; and (4) punishment. Each type plays a different role in both the manner in which and extent to which learning occurs.
