  1. Learning Theories Goal  How do we learn behaviors through classical conditioning?

  2. Learning is… • Relatively permanent • Change in behavior • Due to experience

  3. Habituation

  4. Associative Learning • Learn that certain events occur together Classical Conditioning: associate two stimuli together to anticipate events Operant Conditioning: associate a behavior with a good or bad result

  5. Ivan Pavlov’s Experiment • Studied digestion of dogs • Learn to salivate? • Paired food w/neutral stimulus • Dogs salivated to just the neutral stimulus

  6. Pavlov’s Experiment

  7. UR • UC • CR • CS

  8. Classical Conditioning

  9. Acquisition (CS+UCS) Strength of CR Spontaneous recovery of CR Extinction (CS alone) Extinction (CS alone) Pause Classical Conditioning

  10. Extinction

  11. John B. Watson & “Little Albert” http://www.youtube.com/watch?v=KxKfpKQzow8&feature=related

  12. Generalization = • Discrimination

  13. Generalization

  14. Taste Aversion UC UR CS CR

  15. Factors Influencing Classical Conditioning 1) How consistently CS predicts UCS 2) Number of pairings of CS and UCS 3) Intensity of UCS 4) Time between CS and UCS

  16. Higher-OrderConditioning = = =

  17. But what about…? • Cognitive processes? • Learned helplessness • Biological predispositions? • Garcia & Koelling study  associations may be adaptive
