  1. Pavlovian Conditioning: Basic Concepts Chapter 4

  2. Did you know that: • Pavlov viewed classical conditioning as a technique for studyingthe brain. • Classical Conditioning is not limited to glandular and visceral responses • The conditioned response is not always like the unconditoned response. • Conditioned stimuli become part of the behavior system activated by the unconditioned stimulus. • Pavlovain conditioning often involves S-S learning rather than S-R learning. • Which stimulus can serve as a conditioned stimulus in conditioning dependson the unconditioned stimulus that is used • Associative learning is possible in the random control procedure • Pavlovian conditioning is involved in a wide range of behaviors including preferences and aversions, fears and phobias, drug tolerance and addiction, and maternal and sexual behavior

  3. Pavlov’s Proverbial Bell • Unconditoned Stimulus (US) • Unconditioned Response (UR) • Conditioned Stimulus (CS) • Conditioned Response (CR) Tone (CS) Food (US) CR Salivation (UR)

  4. Pavlov’s Proverbial Bell • Some common misunderstandings about Pavlovian Conditioning • Ivan Pavlov used a bell in his experiments to condition his dogs • Classical conditioning primarily involves the modification of visceral and glandular responses • A UR and a CR need to be the same • What an animal learns in an Pavlovian Conditioning procedure is an association between S-R • Control can be best achieved by random control procedure

  5. Contemporary Pavlovian Conditioning Preparations • APETTITIVE CONDITIONING • Appetitive conditioning preparations are used if the unconditioned stimulus is desirable or appetitive like food. • Skinner box • Autoshaping • Sign Tracking • Head jerking and rearing • So, it is not all about visceral and glandualr responses

  6. Contemporary Pavlovian Conditioning Preparations • AVERSIVE CONDITIONING • Aversive conditioning preparations are used if the unconditioned stimulus is an unpleasant or aversive event • Eye-blink conditioning • Conditoned suppression • Fear Conditioning • Taste Aversion • Fear and amygdala

  7. The Nature of the Conditioned Response • Skeletal vs Glandular Conditioned Responses • Sign tracking / Autoshaping • Eye blink repsonse • Freezing behavior • head-jerk and rearing responses • Similarity of Conditioned and Unconditoned Responses • Jumping (UR) vs Freezing (CR) • The Behavioral System Approach • The conditoned response that develops depends on how the conditioned stimulus becomes incorporated into the behavior system activated by the US • US represeantations

  8. The Contents of Pavlovian Conditioning S-R Learning CS CR • EFFECTS OF US DEVALUATION • EFFECTS OF US INFLATION S-SLearning CS US Representation CR

  9. Stimulus Factors in Classical Conditioning • ATTENTIONAL PROCESSES • CS NOVELTY AND THE LATENT INHIBITION Phase I (CS Preexposure phase) Phase II Test Exp.CS-alone CS-US CS Cont. X CS-US CS • CS-US RELEVANCE AND SELECTIVE ASSOCIATIONS “Effectiveness of a CS depends on the US that is employed” • Garcia Effect
