Classical Conditioning

Updated: 20 June 2020 Classical Conditioning, the first school of Behaviourism, is learning by association – ie: associating one thing with another. The formula is shown in the graphic below. NS = Neutral Stimulus The neutral stimulus on its own is one that does not normally trigger any notable response. UCS = Unconditioned Stimulus UCR = Unconditioned Response The unconditioned stimulus (eg: smell of food) produces an unconditioned response (eg: dog salivating). An unconditioned response is essentially an unlearned innate reflex. It is triggered consistently and automatically by the occurrence of one kind of stimulus. Once such a response is triggered, it is not normally altered for its duration by subsequent events. Experience does little to alter the time course or pattern of the response. When the unconditioned stimulus is paired with the neutral stimulus (eg: sound of door opening) at the same time (‘spontaneous conditioning’) as or immediately before (‘forward conditioning’) the unconditioned stimulus (eg: smell of food), the pairing produces the unconditioned response (salivation). Usually it takes repeated multiple pairings for the association to be made. CS = Conditioned Stimulus CR = Conditioned Response The conditioned stimulus (what was the neutral stimulus) will now produce the conditioned response… Read More
