What is Learning? How would you define learning? Hilgard and Bower definition of learning: Learning refers to the relatively permanent change in a person’s behavior to a given situation brought about by his [or her] repeated experiences in that situation, provided that the behavior change cannot be explained on the basis of native response tendencies, maturation, or temporary states of the person or other animal (e.g., fatigue, drugs, etc.).

Do Now: Listen to the sounds and write down how it makes you feel. http://www.youtube.com/watch?v=Z DcrMScGaj8 http://www.youtube.com/watch?v=Z DcrMScGaj8 http://www.youtube.com/watch?v=yr EvK-tv5OI http://www.youtube.com/watch?v=yr EvK-tv5OI http://www.youtube.com/watch?v=7 acI5z9vyok http://www.youtube.com/watch?v=7 acI5z9vyok Discuss. Why would we feel like that? Where did we learn these feelings?
10
How do you learn? Take some time quietly on your own to take the Learning Style Survey in your workbook
11
Different Types of Learning Classical Conditioning- learn by association of stimuli Operant Conditioning- learn through reinforcement or learning based on the association of consequences with one’s behavior. Social Learning -learn by observing & imitating others. Cognitive Learning -learn through mental processes.
12
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
13
Learning to associate two events Event 1 Event 2 Sea snail associates splash with a tail shock Seal learns to expect a snack for its showy antics
14
Classical or Pavlovian Conditioning We learn to associate two stimuli Two related events: Lightning Stimulus 1 Thunder Stimulus 2 Result after repetition We see lightning Stimulus We wince anticipating thunder Response
15
Classical Conditioning Basics
16
Classical Conditioning Scenario: Pavlov’s dogs Unconditioned Stimulus (US) = food in mouth Unconditioned Response (UR) = salivation Neutral Stimulus (NS) = Tone (bell) NS + US = UR Conditioned Stimulus (CS) = Conditioned Response (CR)
17
The Classic Pavlov Example
18
Conditioning Defined Classical Conditioning- type of learning when you learn to link 2 or more stimuli and anticipate events UR- natural response to the US US- Stimulus naturally and automatically triggers a response CR- learned response to the CS CS- an irrelevant (unnatural) stimulus that, after associating with US comes to trigger a CR NS- stimulus which initially produces no specific response other than focusing attention
19
CC Examples? What classical conditioning scenarios can you think of? Worth Video: Classical Conditioning If the aroma of a cake baking gets your mouth watering, what is the US, the CS, The CR? If the cat comes running when she hears a can opener, what is the US, the CS, the CR? Are you classically conditioned by your phone? Other items?
20
Let’s Experiment Classical Conditioning Experiment ◦With a partner (partner only) get in a space where there is little distraction ◦Choose an experimenter and the subject Experimenter will also be recorder ◦Go through each task in your workbook experiment What happened each time? How was this an example of CC? What was the… ◦US? ◦UR? ◦CR? ◦CS?
21
Operant Conditioning Distinguish general principles of Operant Conditioning Predict Effects of Operant Conditioning HOMEWORK- READ PGS. 228-242 BY WEDNESDAY ◦READING QUIZ ON OPERANT AND CLASSICAL CONDITIONING WEDNESDAY!
22
Learned Helplessness The hopelessness and passive resignation an animal or human learns when unable to avoid repeated aversive events. Learned helpless is usually only talked about in terms of learning. How does it apply socially? ◦Dating ◦Compromising your morals once ◦Girls have cultural pressure to be quiet and not to be angry ◦Becoming victimized and failing to stand up ◦Tendency to close down and not try new approaches when we fail.
23
Operant Conditioning We learn to associate a response and its consequence Response Response: Pushing vending machine button Stimulus Consequence:Receiving a candy bar
24
Operant Conditioning
25
◦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
26
Law of Effect Edward Thorndike’s principle that behaviors followed by favorable consequences become more likely, and behaviors followed by unfavorable consequences become less likely. Thorndike believed that learning is governed by the law of effect. Instrumental learning -responses are strengthened when they are instrumental in producing rewards.

Boo-Hiss! We need three volunteers! Thank you!!! Please wait outside! We need three separate behaviors for our three participants to do Cheers Boos Cheers and Boos Discussion: ◦What did we do? ◦Which approach worked best? What are the benefits? ◦What if we had used punishment?
29
Reinforcement & Punishment
30
Reinforcement vs. Punishment
31
Operant Conditioning Primary reinforcers – unlearned Secondary reinforcers – learned and associated with primary Know reinforcement schedules: ◦Fixed-ratio ◦Variable-ratio ◦Fixed-interval ◦Variable-interval ◦Hint: Intervals involve time; ratios involve behavior What are some examples of each?
32
Operant Conditioning Scenarios In your Workbook and with a partner complete the Operant Conditioning Scenarios
33
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 (when one links a neutral stimulus and an unconditioned stimulus so that the neutral stimulus begins triggering the conditioned response. In operant conditioning, the strengthening of a reinforced response.) ◦greater resistance to extinction (The diminishing of a conditioned response; occurs in classical conditioning when an unconditioned stimulus (US) does not follow a conditioned stimulus (CS); occurs in operant conditioning when a response is no longer reinforced.)
34
Schedules of Reinforcement Fixed Ratio (FR)- Behavior ◦schedule that reinforces a response only after a specified number of responses ◦the faster you respond, the more rewards you get ◦different ratios ◦very high rate of responding ◦like piecework pay
35
Schedules of Reinforcement Variable Ratio (VR) ◦schedule that reinforces a response after an unpredictable number of responses ◦like gambling, fishing ◦very hard to extinguish because of unpredictability
36
Schedules of Reinforcement Fixed Interval (FI)- Time ◦a schedule that reinforces a response only after a specified time has elapsed ◦response occurs more frequently as the anticipated time for reward draws near
37
Schedules of Reinforcement Variable Interval (VI) ◦schedule that reinforces a response at unpredictable time intervals ◦produces slow steady responding ◦like pop quiz
38
Schedules of Reinforcement Variable Interval Number of responses 1000 750 500 250 0 10203040506070 Time (minutes) Fixed Ratio Variable Ratio Fixed Interval Steady responding Rapid responding near time for reinforcement 80

Classical vs. Operant Conditioning http://www.youtube.com/watch?v =H6LEcM0E0io http://www.youtube.com/watch?v =H6LEcM0E0io http://www.youtube.com/user/Pru dential?v=sT7fbayfNBU http://www.youtube.com/user/Pru dential?v=sT7fbayfNBU Is the second video an example of Operant or Classical conditioning? Can you think of examples like this in your own childhood? In your life now?
41
For Review: p. 241 in book
42
Conditioning and Racism On your OWN for 5 minutes write about this question: “How could classical or operant conditioning explain racist behavior?” Be ready to discuss
43
Conditioning and Racism Do you think this type of conditioning happens? ◦What examples can you think of? UCS- UCR CS+ UCS- UCR CS- CR violence- fear race+ violence - fear race- fear Could this model happen through the media? How? Does it happen on the evening news?
44
Conditioning and Racism How can we make racism “extinct”? You would need to present the CS without the UCS, Which means YOU should expose yourself to members of ANOTHER ETHNICITY and their culture to rid yourself of racist conditioning. What about the importance of multi-cultural education, and how this same model can apply to sexism, heterosexism, classism, ageism, etc.??

45
Conditioning Thoughts After watching, what are your thoughts? ◦ be real, be honest, and be authentic Do not put your names on the card
46
Does this Conditioning stuff really work? Behavior Modification Project ◦Make some changes to the assignment Sherwood’s mess ups ◦Complete the questions ◦Establish a plan DUE BY February 27 th ◦Plan on only 2 days of lab time to work on this project ◦It should be done mostly outside of class
47
Delayed Gratification Do now: ◦What types of real-world rewards occur on a delayed schedule? ◦Does the media encourage people to delay gratification? Why or why not? ◦Grades: Do you get a grade for every assignment you turn in in every class? If not, how do you feel if a teacher doesn’t grade everything? ◦Handout 6-4 ◦Discussion
48
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

Little Albert ’ s Fear Conditioning UCS (loud noise) UCR (fear) CS (rat) CS (rat) CR (fear) UCS (loud noise) UCR (fear) Stimulus similar to rat (such as rabbit) Conditioned fear (generalization)
51
Observational Learning ◦learning by observing and imitating the behavior of others Modeling ◦process of observing and imitating behavior Prosocial Behavior ◦positive, constructive, helpful behavior ◦opposite of antisocial behavior
52
Observational Learning Mirror Neurons frontal lobe neurons that fire when performing certain actions or when observing another doing so may enable imitation, language learning, and empathy
