Classical conditioning notes

  1. 1. Chapter 6 Classical Conditioning Notes
  2. 2. Ivan Pavlov Rings a Bell  Conducted an experiment to see if he could get dogs to salivate in response to any stimulus (something that produces a reaction) that he chose.  He rang a bell seconds before giving the dogs food and repeated this several times  Then he rang the bell, but did not give the dogs food afterward  The dogs still salivated in response to the bell
  3. 3. Letters of Learning  Unconditioned stimulus (US)- stimulus that causes a response that is automatic or not learned  The dog food  Unconditioned response (UR)- automatic response  Salivating for the dog food
  4. 4. Letters of Learning  Conditioned stimulus (CS)- stimulus that is repeatedly associated with the unconditioned stimulus  Bell  Conditioned response (CR)- learned response to a stimulus that was previously meaningless  Salivating when they hear the bell ring
  5. 5. Applications of Classical Conditioning  Taste aversion- a learned avoidance of a particular food  Example: if you have ever gotten food poisoning and then could not eat that kind of food for a long time?  Extinction- when the conditioned stimulus is disconnected from the unconditioned stimulus  Example: if Pavlov keeps ringing the bell, but stops giving the dogs food, they will stop salivating when the bell rings  Spontaneous recovery- the reappearance, after a pause, of an extinguished conditioned response
  6. 6. Applications of Classical Conditioning  Generalization- responding in the same ways to stimuli that seem to be similar  Example: the dogs may salivate when they hear a chime  Discrimination- responding differently to stimuli that aren’t similar to each other
  7. 7. Applications to help change behavior  Flooding- exposing a person to the stimulus until the fear is gone  Systematic desensitization- taking baby steps to rid a person of a fear  Counter-conditioning- pleasant stimulus is repeatedly paired with a fearful one
