1 AP Psychology Unit: Learning

2 Learning How do classical and operant conditioning each explain learning? What impact does the cognitive process have on learning?

3 Classical Conditioning
EQ: How is behavior affected by classical and operant conditioning?

4 Vocabulary Learning Unconditioned Conditioned Stimulus Response
Generalization Extinction Spontaneous Recovery Higher-Order Conditioning Taste Aversion

5 Learning The modification through experience of preexisting behavior and understanding Habituation The process of adapting to stimuli that do not change. Dishabituation The reappearance of your original response when a stimulus changes Sensitization Increase in responsiveness to a stimuli

6 Define the Terms Unconditioned Stimuli Unconditioned Response
Neutral Stimuli Conditioned Stimuli Conditioned Response

7 Pavlov’s Experiment (Identify the Parts)
Unconditioned Stimuli Unconditioned Response Neutral Stimuli Conditioned Stimuli Conditioned Response

8 Pavlov’s Dog

9 Watson’s Experiment (Identify the Parts)
Unconditioned Stimuli Unconditioned Response Neutral Stimuli Conditioned Stimuli Conditioned Response

10 Generalization and Discrimination
Stimulus Generalization: A phenomenon in which a conditioned response is elicited by stimuli that are similar but not identical to the conditioned stimulus Stimulus Discrimination: A process through which individuals learn to differentiate among similar stimuli and respond appropriately to each one

12 Extinction and Spontaneous Recovery
Figure 6.5 Idealized curve of acquisition, extinction, and spontaneous recovery The rising curve shows that the CR rapidly grows stronger as the CS and US are repeatedly paired (acquisition), then weakens as the CS is presented alone (extinction). After a pause, the CR reappears (spontaneous recovery). © 2011 by Worth Publishers

13 Garcia and Koelling (1966) Study
Biological preparedness: tendency of animals to learn certain associations, such as taste and nausea with only a few pairings due to the survival value of the learning. Disproved Pavlov’s ideas concerning one trial learning, close temporal proximity, & equipotentiality. NS UCS Learned (CR) Food, Light, & Clicker Shock Avoid Light (CS) and Clicker (CS) Radiation (nausea) Avoid Food (CS)

14 Learned Taste Aversions
Are there any foods that you cannot eat or could not eat at one time due to food poisoning or some other sickness that you had at the time? A.k.a The Garcia Effect When it comes to food being paired with sickness, the conditioning is incredible strong. Even when food and sickness are hours apart. Food must be salient (noticeable.)

15 Aversion Therapy A form of behavior therapy in which an aversive (causing a strong feeling of dislike or disgust) stimulus is paired with an undesirable behavior in order to reduce or eliminate that behavior. Unpleasant sensations are associated with behavior, and behavior decreases or stops. Differs from principles of operant conditioning. In operant therapy, the aversive stimulus, usually called punishment, is presented after the behavior rather than together with it.

16 EQ: How is behavior affected by classical and operant conditioning?

17 Review and Preview

18 Vocabulary Positive Reinforcement Negative Reinforcement Punishment
Discrimination Shaping Chaining Fixed Ratio Variable Ratio Fixed Interval Variable Interval

19 Edward Thorndike’s Puzzle Box
Instrumental Conditioning: Responses are strengthened when they are instrumental in producing a reward Law of Effect: If an action is followed by a pleasurable consequence , it will be repeated, and if followed by an unpleasant consequence, it will not be repeated.

21 B.F. Skinner Operant Conditioning: The focus is on the effect of consequences on voluntary (operant) behavior.

22 Reinforcement Primary Reinforcer Secondary Reinforcer (Token Economy)

23 Operant Conditioning

24 Reinforcement and Punishment

25 Big Bang Theory: Operant Conditioning
Find the Mistake Mistake Explained

26 Partial Reinforcement Schedule
FIXED VARIABLE RATIO (# of Occurrences) INTERVAL (Passage of Time)

27 Partial Reinforcement Schedule

28 Figure 6.13 Intermittent reinforcement schedules Skinner’s laboratory pigeons produced these response patterns to each of four reinforcement schedules. (Reinforcers are indicated by diagonal marks.) For people, as for pigeons, reinforcement linked to number of responses (a ratio schedule) produces a higher response rate than reinforcement linked to amount of time elapsed (an interval schedule). But the predictability of the reward also matters. An unpredictable (variable) schedule produces more consistent responding than does a predictable (fixed) schedule. © 2011 by Worth Publishers

29 Operant Conditioning at Work

30 Activator Other that through classical and operant conditioning, how else does one learn?

31 Cognitive Factors in Learning
EQ: How is behavior affected by cognitive learning?

32 Vocabulary Latent learning Cognitive Map (Mental Map) Insight
Learned Helplessness Observational Learning Albert Bandura Edward Tolman Wolfgang Kohler Martin Seligman

33 Cognitive Maps and Latent Learning
Edward Tolman’s Maze Study Latent Learning: learning that remains hidden until its application becomes useful Challenged Skinner’s Theory (How?) Cognitive/Mental Maps: Mental representations people rely on to understand complex patters. Examples???

34 Kohler’s Insight Learning
How were the chimpanzees able to demonstrate insight? Insight: a sudden “coming together” of all elements of a problem in a kin of “aha” moment Example of insight learning

35 Seligman’s Learned Helplessness
Definition: Failure to continue exerting effort for an outcome because all previous attempts have failed Martin Seligman’s (founder of positive psychology) Dog Study: Original intent was to study escape or avoidance learning Related it to Depression

36 Albert Bandura and Observational Learning
Observational Learning: learning new behavior by watching a model perform that behavior Modeled: imitated the behavior that was observed

37 Cognitive Differences: Humans and Chimpanzees
According to the video, how does the learning behavior differ between human children and chimpanzees?
