Introductory Definitions
Learning (relatively permanent change in behavior or mental processes resulting from practice or experience) Conditioning (process of learning associations between environmental stimuli and behavioral responses) ©John Wiley & Sons, Inc Huffman: Psychology in Action (8e)
4
Classical Conditioning
Pavlov’s Contribution Classical Conditioning: learning that occurs when a neutral stimulus (NS) becomes paired (associated) with an unconditioned stimulus (UCS) to elicit a conditioned response (CR) ©John Wiley & Sons, Inc Huffman: Psychology in Action (8e)
5
Pavlov’s Original Experiment

6
Classical Conditioning--Key Terms
Neutral Stimulus (NS): stimulus that, before conditioning, doesn’t naturally bring about the response of interest Unconditioned Stimulus (UCS): stimulus that elicits an UCR occurring without previous conditioning Unconditioned Response (UCR): unlearned reaction to an UCS occurring without prior conditioning ©John Wiley & Sons, Inc Huffman: Psychology in Action (8e)
7
Classical Conditioning--Key Terms (Continued)
Conditioned Stimulus (CS): previously NS that, through repeated pairings with an UCS, now causes a CR Conditioned Response (CR): learned reaction to a CS occurring because of previous repeated pairings with an UCS ©John Wiley & Sons, Inc Huffman: Psychology in Action (8e)

John B. Watson Conditioned Emotional Response (CER): Watson demonstrated how emotions can be classically conditioned to a previously neutral stimulus (NS). ©John Wiley & Sons, Inc Huffman: Psychology in Action (8e)

Classical Conditioning’s Basic Principles
ALL Snakes bite! Stimulus Generalization: learned response to stimuli that are similar to the original conditioned stimuli (CS) ©John Wiley & Sons, Inc Huffman: Psychology in Action (8e)
14
Classical Conditioning’s Basic Principles (Continued)
Now I know that some snakes are nice! Stimulus Discrimination: learned response to a specific stimulus, but not to other, similar stimuli ©John Wiley & Sons, Inc Huffman: Psychology in Action (8e)
15
©John Wiley & Sons, Inc. 2007 Huffman: Psychology in Action (8e)
Extinction: gradual weakening or suppression of a previously conditioned response (CR) Spontaneous Recovery: reappearance of a previously extinguished conditioned response (CR) ©John Wiley & Sons, Inc Huffman: Psychology in Action (8e)
16
Classical Conditioning’s Basic Principles (Continued)
Higher-Order Conditioning: neutral stimulus (NS) becomes a conditioned stimulus (CS) through repeated pairings with a previously conditioned stimulus (CS) ©John Wiley & Sons, Inc Huffman: Psychology in Action (8e)

Operant Conditioning Operant Conditioning: learning in which voluntary responses are controlled by their consequences ©John Wiley & Sons, Inc Huffman: Psychology in Action (8e)
19
Operant Conditioning (Continued)
Thorndike’s Contribution Law of Effect: the probability of an action being repeated is strengthened when followed by a pleasant or satisfying consequence ©John Wiley & Sons, Inc Huffman: Psychology in Action (8e)
20
Operant Conditioning (Continued)
Skinner’s Contribution Conducted systematic research using a Skinner box ©John Wiley & Sons, Inc Huffman: Psychology in Action (8e)
21
Operant Conditioning’s Basic Principles
Reinforcement: strengthening a response ©John Wiley & Sons, Inc Huffman: Psychology in Action (8e)
22
Operant Conditioning’s Basic Principles (Continued)
Primary Reinforcers: normally satisfy an unlearned biological need (e.g., food) Secondary Reinforcers: learned value (e.g., money, praise) ©John Wiley & Sons, Inc Huffman: Psychology in Action (8e)
23
Operant Conditioning’s Basic Principles (Continued)
Positive Reinforcement: adding (or presenting) a stimulus, which strengthens a response and makes it more likely to recur (e.g., praise) ©John Wiley & Sons, Inc Huffman: Psychology in Action (8e)
24
Operant Conditioning’s Basic Principles (Continued)
Negative Reinforcement: taking away (or removing) a stimulus, which strengthens a response and makes it more likely to recur (e.g., headache removed after taking an aspirin) ©John Wiley & Sons, Inc Huffman: Psychology in Action (8e)

26

Operant Conditioning’s Basic Principles: Four Partial Schedules of Reinforcement Fixed Ratio (FR): reinforcement occurs after a predetermined set of responses; the ratio (number or amount) is fixed 2. Variable Ratio (VR): reinforcement occurs unpredictably; the ratio (number or amount) varies ©John Wiley & Sons, Inc Huffman: Psychology in Action (8e)
27
©John Wiley & Sons, Inc. 2007 Huffman: Psychology in Action (8e)
Operant Conditioning’s Basic Principles: Four Partial Schedules (Continued) Fixed Interval (FI): reinforcement occurs after a predetermined time has elapsed; the interval (time) is fixed 4. Variable Interval (VI): reinforcement occurs unpredictably; the interval (time) varies ©John Wiley & Sons, Inc Huffman: Psychology in Action (8e)

Operant Conditioning’s Basic Principles: Four Partial Schedules (Continued) If you want to increase the overall number of responses, which schedule of reinforcement should you choose? ©John Wiley & Sons, Inc Huffman: Psychology in Action (8e)
30
Operant Conditioning’s Basic Principles (Continued)
Shaping: reinforcement is delivered for successive approximations of the desired response ©John Wiley & Sons, Inc Huffman: Psychology in Action (8e)
31
Operant Conditioning’s Basic Principles (Continued)
Punishment: weakening a response ©John Wiley & Sons, Inc Huffman: Psychology in Action (8e)
32
Operant Conditioning’s Basic Principles (Continued)
Positive Punishment: adding (or presenting) a stimulus that weakens a response and makes it less likely to recur (e.g., shouting) ©John Wiley & Sons, Inc Huffman: Psychology in Action (8e)
33
Operant Conditioning’s Basic Principles (Continued)
Negative Punishment: taking away (or removing) a stimulus that weakens a response and makes it less likely to recur (e.g., restriction) ©John Wiley & Sons, Inc Huffman: Psychology in Action (8e)
