UCS - alcohol
UCR - sense of well-being
CS - smell of alcohol
CR - sense of well-being
Alcohol (UCS) causes the UCR; UCS automatically cause (UCR) a sense of well-being, without previous conditioning .
Since the smell of alcohol is paired repeatedly with actual alcohol (UCS), it is likely to eventually elicit the UCR (sense of well-being) .
Sense of well-being is the UCR to the UCS of alcohol, the smell of alcohol (CS) is likely to eventually elicit the CR of a sense of well-being .
The presentation of the CS (smell of alcohol) without the UCS (alcohol), with repeated pairings, will eliminate the conditioned response (CR). Therefore, extinction has taken place.
