Document Summary
Involves an association with a simple stimulus that is neutral paired with a signi cant event. One trial of conditioning - training to associate two stimuli - sound then treat. * means its important and importance is not learned. Biologically signi cant stimuluses are food, alcohol, drugs, pain/fear, nurture, aggression, water/beer, sleep, sex. Present tone (cs) followed by foot-shock (us), the rats jump. After conditioning the cs can be presented without the us and the rats will show an aversive reaction (jump) With dogs you can measure the reaction to just the cs by salivation or approach (this is called conditioned approach because it is learned), motivation/emotional arousal (wagging tail and getting excited when you pick up their leash. With the rat experiment, the cs would be fear/negative motivation (emotional arousal) Rats in fear do not jump, they freeze, that is the conditioned response.
