A behaviour pattern that grows more frequent when it is followed by a reward is operant conditioning, where consequences shape voluntary behaviour.

B.F. Skinner demonstrated this with the Skinner box, where a rat pressing a lever for food repeated the action.

Shaping is a technique within operant conditioning that reinforces successive approximations toward a target behaviour, not the reward-frequency law itself.

Classical conditioning, from Pavlov, pairs two stimuli so a neutral stimulus triggers a reflex, dealing with involuntary responses.

Generalization is the tendency to give the same response to stimuli similar to the original conditioned one.

The reward that raises response frequency is a positive reinforcer, distinct from punishment, which lowers it.
