Classical Conditioning

Bell (CS) alone elicits salivation (CR).


Phase III: After Conditioning Phase

To determine if conditioning (learning) occurred, Pavlov presented the Conditioned Stimulus alone and the dog salivated. This CHANGE in behavior towards the bell tone meant learning occurred. Initially, the dog did not salivate to the bell tone. After learning occurred, the dog salivated when the bell tone was presented.

When Classical Conditioning occurs, the CS elicits the CR, subsequently the CS predicts the occurrence of the UCS.
