Classical Conditioning

~ A type of learning in which one learns to link two or more stimuli and anticipate events

Pavlov's Dogs

Ivan Pavlov discovered the benefits of this technique

Pavlov presented a neutral stimulus (tone) just before an unconditioned stimulus (food in the mouth). The neutral stimulus then became a conditioned stimulus, producing a conditioned response

The NEUTRAL STIMULUS, after conditioning, becomes the CONDITIONED STIMULUS



Real Life Example

Key Terms

Acquisition: The Initial stage when one links a neutral stimulus and an unconditioned stimulus so that the neutral stimulus begins triggering the conditioned response

Extinction: The diminishing of a conditioned response when an unconditioned stimulus does not follow  a conditioned stimulus

Spontaneous Recovery: The reappearance after a pause of an extinguished conditioned response.

Generalization: The tendency once a response has been conditioned for stimulus similar to the conditioned stimulus to elicit similar responses.

Discrimination: the learned ability to distinguish between a conditioned stimulus and  stimuli that do not signal an unconditioned stimulus.


John Garcia and Robert Koelling

While researching the effects of radiation on lab animals, they recognized that rats began to avoid drinking water from the plastic bottles in the radiation chambers. They soon concluded that they the rats had been classically conditioned. They had linked the plastic-tasting water (CS) to the sickness (UR) which was triggered by the radiation (US).
