These two forms of learning have similarities and differences. Their similarities are that they both produce basic phenomena. One such phenomenon is acquisition. Both types of conditioning result in the inheritance of a behavior.
One of the most famous of experiments that illustrates classical conditioning is Pavlov's Dogs. In this experiment, Pavlov sat behind a one-way mirror and controlled the presentation of a bell. The bell was the conditioned stimulus. A conditioned stimulus was an originally neutral stimulus that could eventually produce a desired response when presented alone. Directly after the ringing of the bell, Pavlov gave the dog food. The food was the unconditioned stimulus. This means that the food caused an uncontrollable response whenever it was presented alone. That response would be the salivation of the dog. A tube that was in the dog's mouth then measured the saliva. When the unconditioned stimulus (US) was paired with a conditioned stimulus (CS), it eventually resulted in a conditioned response. Extinction results if there is a decrease in frequency or strength of a learned response due to the failure to continue to pair the US and the CS.
Extinction can also occur in operant conditioning. The key to operant
