Document Summary
Lec02 lecture overview: early studies, adaptive significance, what is learnt in pavlovian conditioning, excitatory vs inhibitive conditioning b. stimulus-stimulus vs stimulus-response, nature of conditioned response (cr, neural basis of pavlovian conditioning pavlov and the dog. 1. loud bang noise = us (aversive stimulus) 2. fear / startle = ur (behavior / response: white rat = cs (conditioned stimulus properties of pavlovian conditioning, acquisition period, when cs and us is paired, extinction period, presentation of cs without presentation of us, us withheld. 3. spontaneous recovery: cs presented again with us stimulus generalization and discrimination. 1. little albert conditioned to fear white rats. 2. signal for food: anticipatory responses (salivation / flow of gastric juices / mobilization of insulin) for efficient digestion of food, anticipatory signals inducing aversion to food that cause illness. 3. signal for fearful events a. fear associated cues allow animals to prepare for a dangerous encounter: e. g. freezing response.
