Operant Conditioning

Relaunched: 3 May 2020 Unlike Classical Conditioning, which is based on association, Operant Conditioning is based on consequences. The basic principle is that behaviour which brings reward is likely to be repeated to gain the reward again, thus reinforcing the behaviour; on the other hand, behaviour which brings punishment is unlikely to be repeated, to avoid the punishment. Operant Conditioning has its roots in the ‘instrumental learning’ work of Edward Thorndike (1905). His Law of Effect stated positive effects (rewards) of some behaviours ‘stamped in’ those behaviour while negative effects (punishments) of other behaviours ‘stamped out’ those behaviours. Thorndike had developed his ideas from ‘puzzle box’ experiments, usually with cats. Typically he placed a hungry, young and active cat in a box from which it could only escape by pulling on a loop attached to a string. (In later studies Thorndike used buttons and levers.) To motivate the hungry cat to escape, Thorndike hung fish outside the puzzle box door. The cat initially scratched, clawed and miaowed, exploring all corners and openings in the box and trying to squeeze out. Eventually it clawed at the loop, causing the door to open and allowing the cat to get the fish. On successive… Read More
