Pavlov spent the rest of his life outlining his ideas. He came up with 5 critical principles that together make up classical conditioning. • Acquisition • Extinction • Spontaneous Recovery • Generalization • Discrimination
Classical Conditioning • We know learning exists because the CS is linked to the UCS. • This is called ACQUISITION.
Acquisition • Contiguity • The CS should come before the UCS • They should be very close together in timing. • Contingency • learning is better when the UCS and CS occur together frequently. • Novelty • learning is better when the CS is new or unique. • Can actually lead to superstition!
Extinction • Acquisition does not last forever. • The moment the CS is no longer associated with the UCS, we have EXTINCTION. Reconditioning: the quick relearning of a CR after extinction
Spontaneous Recovery • Sometimes, after extinction, the CR still randomly appears after the CS is presented.
Grandpa/Church Example Stimulus Generalization and Discrimination Generalization Discrimination Something so different to the CS so you do not get a CR. • Something is so similar to the CS that you get a CR.
Generalization v. Discrimination • We stop our vehicles when the traffic light is red, but continue through the light when it is green. • We sit quietly in our seats during class examinations, church services, theatrical presentations, and funerals. • We raise our hands before speaking in class but not while talking to a friend or while at a party. • We put our feet up on our desk and coffee table at home, but not on our grandparents' coffee table. • We mistake a stranger for a friend of ours. • We answer the doorbell when it was really the phone that was ringing.
Practice: • Every time a cancer patient goes into the office where she receives chemotherapy, she is assigned to the same nurse. The chemotherapy makes her nauseous. Seeing the nurse makes her nauseous too. • Identify the UCS, UCR, NS, CS, CR & give an example of how the following may occur: • Extinction • Spontaneous Recovery • Generalization • Extinction
Little Albert • John Watson – famous behavioralist • Little Albert – 11 month old orphan • Showed him a white rat. No fear. • Made a loud noise. Albert cried. • Showed him a white rat and made a loud noise. Albert cried. Repeated several times. • Eventually Albert cried at white rat alone.
