In psychology, Operant conditioning is a method of learning that occurs through rewards (that increase the probability for one behavior to take place) and punishments (that decrease the probability for one behavior to take place).

Operant conditioning appeared after classical conditioning, since psychologists started to think that classical conditioning was too simple when explaining behaviors. The most famous psychologist who is associated with operant conditioning was B. F. Skinner and he is considered the father of operant conditioning.
