Presentation Transcript

1. Myers’ PSYCHOLOGY (5th Ed) Chapter 8 Learning James A. McCubbin, PhD Clemson University Worth Publishers

2. Learning Learning relatively permanent change in an organism’s behavior due to experience experience (nurture) is the key to learning

3. Association We learn by association Our minds naturally connect events that occur in sequence Aristotle 2000 years ago John Locke and David Hume 200 yrs ago Associative Learning learning that two events occur together two stimuli a response and its consequences

4. Classical or Pavlovian Conditioning We learn to associate two stimuli

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

6. 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

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

8. Classical or Pavlovian Conditioning Pavlov’s device for recording salivation

9. Classical or Pavlovian Conditioning Classical Conditioning organism comes to associate two stimuli lightning and thunder tone and food begins with a reflex a neutral stimulus is paired with a stimulus that evokes the reflex neutral stimulus eventually comes to evoke the reflex

10. Classical or Pavlovian Conditioning Unconditioned Stimulus (UCS) effective stimulus that unconditionally-automatically and naturally- triggers a response Unconditioned Response (UCR) unlearned, naturally occurring automatic response to the unconditioned stimulus salivation when food is in the mouth

11. Classical or Pavlovian Conditioning Conditioned Stimulus (CS) previously neutral 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

12. Conditioning Acquisition the initial stage of learning, during which a response is established and gradually strengthened in classical conditioning, the phase in which a stimulus comes to evoke a conditioned response in operant conditioning, the strengthening of a reinforced response

13. 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

14. Classical or Pavlovian Conditioning

15. Classical or Pavlovian Conditioning Spontaneous recovery reappearance, after a rest period, of an extinguished CR Generalization tendency for a stimuli similar to CS to evoke similar responses

16. Classical or Pavlovian Conditioning Discrimination in classical conditioning, the ability to distinguish between a CS and other stimuli that do not signal and UCS in operant conditioning, responding differently to stimuli that signal a behavior will be reinforced or will not be reinforced

17. Generalization

18. Classical or Pavlovian Conditioning

19. Nausea Conditioning in Cancer Patients

20. 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

21. Operant Conditioning Operant Behavior complex or voluntary behaviors push button, perform complex task operates (acts) on environment produces consequences Respondent Behavior occurs as an automatic response to stimulus behavior learned through classical conditioning

22. Operant Conditioning B.F. Skinner (1904-1990) elaborated Thorndike’s Law of Effect developed behavioral technology

23. Operant Conditioning Skinner Box soundproof chamber with a bar or key that an animal presses or pecks to release a food or water reward contains a device to record responses

24. Operant Conditioning Reinforcer any event that strengthens the behavior it follows Shaping conditioning procedure in which reinforcers guide behavior toward closer approximations of a desired goal Successive Approximations reward behaviors that increasingly resemble desired behavior

25. Principles of Reinforcement Primary Reinforcer innately reinforcing stimulus satisfies a biological need Secondary Reinforcer conditioned reinforcer learned through association with primary reinforcer

26. Schedules of Reinforcement Continuous Reinforcement reinforcing the desired response each time it occurs learning occurs rapidly extinction occurs rapidly Partial Reinforcement reinforcing a response only part of the time results in slower acquisition greater resistance to extinction

27. Schedules of Reinforcement Fixed Ratio (FR) reinforces a response only after a specified number of responses faster you respond the more rewards you get different ratios very high rate of responding like piecework pay

28. Schedules of Reinforcement Variable Ratio (VR) reinforces a response after an unpredictable number of responses average ratios like gambling, fishing very hard to extinguish because of unpredictability

29. Schedules of Reinforcement Fixed Interval (FI) reinforces a response only after a specified time has elapsed response occurs more frequently as the anticipated time for reward draws near

30. Schedules of Reinforcement Variable Interval (VI) reinforces a response at unpredictable time intervals produces slow steady responding like pop quiz

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

32. Problems with Punishment Punished behavior is not forgotten, it's suppressed- behavior returns when punishment is no longer eminent Causes increased aggression- shows that aggression is a way to cope with problems- Explains why aggressive delinquents and abusive parents come from abusive homes

33. Problems with Punishment Creates fear that can generalize to desirable behaviors, e.g. fear of school, learned helplessness, depression Does not necessarily guide toward desired behavior- reinforcement tells you what to do--punishment tells you what not to do- Combination of punishment and reward can be more effective than punishment alone Punishment teaches how to avoid it

34. Cognition and Operant Conditioning Cognitive Map mental representation of the layout of one’s environment example- after exploring a maze, rats act as if they have learned a cognitive map of it Latent Learning learning that occurs, but is not apparent until there is an incentive to demonstrate it

35. Latent Learning

36. Observational Learning Observational Learning learning by observing and imitating others Modeling process of observing and imitating behavior Prosocial Behavior positive, constructive, helpful behavior opposite of antisocial behavior
