  1. Myers’ PSYCHOLOGY (7th Ed) Chapter 8 Learning James A. McCubbin, PhD Clemson University Worth Publishers

  2. Learning • Learning • change in behavior due to experience

  3. Association • learn by association • Our minds naturally connect events that occur in sequence • Associative Learning • learning that two events occur together • two stimuli • a response and its consequences

  4. Association Event 1 Event 2 • Learning to associate two events Sea snail associates splash with a tail shock Seal learns to expect a snack for its showy antics

  5. Classical or Pavlovian Conditioning • We learn to associate two stimuli

  6. Operant Conditioning • We learn to associate a response and its consequence

  7. Classical Conditioning • Ivan Pavlov • 1849-1936 • Russian physician/ neurophysiologist • Nobel Prize in 1904 • studied digestive secretions

  8. Pavlov’s Classic Experiment Before Conditioning UCS (food in mouth) Neutral stimulus (tone) UCR (salivation) No salivation During Conditioning After Conditioning UCS (food in mouth) CS (tone) Neutral stimulus (tone) UCR (salivation) CR (salivation)

  9. Classical Conditioning • Pavlov’s device for recording salivation

  10. Classical Conditioning • Classical Conditioning • learn to associate two stimuli • a neutral stimulus that signals an unconditioned stimulus produces response that prepares for the unconditioned stimulus

  11. Behaviorism • John B. Watson • viewed psychology as objective science • generally agreed-upon consensus today • recommended study of behavior without reference to unobservable mental processes • not universally accepted by all schools of thought today

  12. Classical Conditioning • Unconditioned Stimulus (UCS) • stimulus that unconditionally--automatically -triggers a response • Unconditioned Response(UCR) • unlearned, naturally occurring response to the unconditioned stimulus • salivation when food is in the mouth

  13. Classical Conditioning • Conditioned Stimulus (CS) • originally irrelevant stimulus that, after association with an unconditioned stimulus, comes to trigger a conditioned response • Conditioned Response (CR) • learned response to a previously neutral conditioned stimulus

  14. Classical Conditioning • Extinction • diminishing of a CR • in classical conditioning, when a UCS does not follow a CS • in operant conditioning, when a response is no longer reinforced

  15. UCS (drug) UCR (nausea) CS (waiting room) UCS (drug) UCR (nausea) CS (waiting room) CR (nausea) Nausea Conditioning in Cancer Patients

  16. Operant Conditioning • Operant Conditioning • type of learning in which behavior is strengthened if followed by reinforcement or diminished if followed by punishment • Law of Effect • Thorndike’s principle that behaviors followed by favorable consequences become more likely, and behaviors followed by unfavorable consequences become less likely

  17. Operant Conditioning • B.F. Skinner (1904-1990)

  18. Operant Chamber • Skinner Box • chamber with a bar or key that an animal manipulates to obtain a food or water reinforcer • contains devices to record responses

  19. Operant Conditioning • Reinforcer • any event that strengthens the behavior it follows

  20. Operant Conditioning

  21. Principles of Reinforcement • Primary Reinforcer • innately reinforcing stimulus • i.e., satisfies a biological need • Conditioned Reinforcer • stimulus that gains its reinforcing power through its association with primary reinforcer • secondary reinforcer

  22. Punishment • Punishment • aversive event that decreases the behavior that it follows • powerful controller of unwanted behavior

  23. Punishment

  24. Cognition and Operant Conditioning • Intrinsic Motivation • Desire to perform a behavior for its own sake and to be effective • Extrinsic Motivation • Desire to perform a behavior due to promised rewards or threats of punishments

  25. Operant vs Classical Conditioning

  26. Observational Learning • Observational Learning • learning by observing others • Modeling • process of observing and imitating a specific behavior
