1 LEARNING * A relatively permanent change in behavior or knowledge resulting from experience

2 Classical Conditioning * Image attributed to Stangor, 2011. Introduction to Psychology Learning by association A neutral stimulus becomes associated with a stimulus that naturally produces a behavior (e.g. a reflex) Pavlov Video

3 Defining Terms Unconditioned Stimulus (US)* Naturally produces unconditioned response * Unconditioned Response (UR) – reflexive, innate Neutral stimulus (NS) produces no response. After pairing US & NS (conditioning), then NS becomes CS (conditioned stimulus *) CS = learned stimulus Conditioned stimulus produces conditioned response (CR) = learned response Student Experiment in Classical Conditioning (video) Student Experiment in Classical Conditioning

4 Terms in Classical Conditioning Stimulus Generalization * (Watson & Little Albert) Respond to similar NS as if they were CS. Stimulus Discrimination * Learn to respond differently to similar stimuli Extinction * Remove US, present CS, response gradually declines Spontaneous Recovery * Learned response returns after extinction. Image attributed to Stangor, 2011. Introduction to Psychology

5 Nature and Classical Conditioning Phobia * Unreasonable fear causing distress or dysfunction. Related to evolution – adaptive fears. What phobia do you have? How did evolution prepare you to develop this fear? Taste Aversion * One trial learning after sickness from food Do you have a personal experience? Post Traumatic Stress Disorder * Strong associative learning with stress/fear.

6 Practical Application: Advertising Goal = learned association between product and natural, positive feeling (e.g. sexual arousal, nice mood, good taste, relaxation) Budweiser Ad video Associations with fear also work Most successful when: Little knowledge of products Little difference between products. Consumer doesn’t think carefully or critically.

7 2. Operant Conditioning * Thorndike’s Law of Effect * Learning Based on Consequences (video) Learning Based on Consequences B.F. Skinner Consequences determine frequency of behavior Reinforcement * Increases the frequency of behavior Punishment * Suppresses behavior Skinner video

8 Key Concepts Reinforcer * Anything that increases behavior Video What reinforces you? How does this change over time? Extinction * Remove reinforcers, behavior decreases Discriminative Stimulus * Cue for availability of reinforcement VideoVideo Generalization * Treat similar stimuli as discriminative stimulus

9 More Key Concepts Shaping * Reinforcement for successive approximations to the target behavior Shaping VideoShaping Video Primary reinforcer * Natural, biological –e.g. food, water, sleep Secondary reinforcer * Learned, social or exchange value

10 Practice Analyzing Operant Conditioning Watch this video: Clicker TrainingClicker Training What behavior is being shaped? What is the primary reinforcer? What is the secondary reinforcer? What is the role of patience in operant conditioning? What human behaviors could you shape with operant conditioning?

11 Positive & Negative Reinforcement Positive reinforcement * Increases behavior when given Negative reinforcement * Increases behavior when removed Positive and Negative Reinforcement (video) Positive and Negative Reinforcement What will the mother do the next time the child cries? What do you anticipate will happen if the mother and child continue this pattern?

12 Punishment * Suppresses behavior What makes punishment more effective? Consistent, immediate, administered by respected person, appropriate, combined with reinforcement for alternate behavior Possible Problems with Punishment? Models aggression Increases negative emotions: anger, depression, anxiety Bad feelings towards punishing agent Possibility of abuse, loss of control Do not learn how to get what you wanted Increases negative behaviors – aggression, withdrawal, learned helplessness

13 Learned Helplessness Giving Up (video) Giving Up Seligman’s research with dogs. Repeated punishment or failure can lead to learned helplessness. What happens when a person repeatedly tries to achieve a goal and is punished for trying? What are some examples of when learned helplessness occurs?

14 Behavior Modification * Applying the principles of conditioning to change behavior. Behavior Modification of Preschooler (video) Behavior Modification of Preschooler Outline the steps you would take to get a child to do their chores without complaining. How would you set up a behavior modification program in a prison?

15 Cognition and Conditioning Can you be controlled? How do you respond when you know someone is trying to shape your behavior? Variables include: Awareness Anticipation Expectations videovideo Planning, Counter-control Do you negotiate conditions & consequences for your behavior?

16 3. Insight and Latent Learning Mental Combinations (video) Mental Combinations How does this demonstrate insight learning? Chimpanzee "Insight“ (video) Chimpanzee "Insight“ How is this insight learning more complex? Give an example of how you learn by putting together ideas. Tolman – Latent learning and cognitive maps. Cognitive Map (video) Cognitive Map

17 4. Observational Learning * Learning by observing the behavior of others. Bandura's Bobo Doll Experiment (video) Bandura's Bobo Doll Experiment What are the implications for media viewing? Variables which influence modeling include: Similarity, proximity, frequency Personality of viewer, attention Attractiveness of model, alternate models List some positive and negative examples of observational learning.
