Lecture Overview • Classical Conditioning • Operant Conditioning • Cognitive-Social Learning • The Biology of Learning • Using Conditioning and Learning Principles ©John Wiley & Sons, Inc. 2007 Huffman: Psychology in Action (8e)
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. 2007 Huffman: Psychology in Action (8e)
Ivan Pavlov Classical Conditioning:learning that occurs when a neutral stimulus (NS) becomes paired (associated) with an unconditioned stimulus (UCS) to elicit a conditioned response (CR) Classical Conditioning ©John Wiley & Sons, Inc. 2007 Huffman: Psychology in Action (8e)
Pavlov’s Original Experiment ©John Wiley & Sons, Inc. 2007 Huffman: Psychology in Action (8e)
Classical Conditioning--Key Terms • Neutral Stimulus(NS): before conditioning doesn’t naturally elicit response of interest • Unconditioned Stimulus (UCS): elicits UCR without previous conditioning • Unconditioned Response (UCR): unlearned reaction to UCS occurring without prior conditioning ©John Wiley & Sons, Inc. 2007 Huffman: Psychology in Action (8e)
Classical Conditioning--Key Terms (Continued) • Conditioned Stimulus(CS): previously NS that, through repeated pairings with 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. 2007 Huffman: Psychology in Action (8e)

Classical Conditioning’s Basic Principles ALL Snakes bite! • Stimulus Generalization: learned response to stimuli that are similarto the original conditioned stimuli (CS) ©John Wiley & Sons, Inc. 2007 Huffman: Psychology in Action (8e)
Stimulus Discrimination: learned response to a specific stimulus, but not to other, similar stimuli Classical Conditioning’s Basic Principles (Continued) Now I know that some snakes are nice! ©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. 2007 Huffman: Psychology in Action (8e)
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. 2007 Huffman: Psychology in Action (8e)

Pause and Reflect: Check & Review • Using Pavlov’s classic experiment with the salivating dog, can you label the NS, UCS, UCR, CS, and CR? • Compare and contrast stimulus generalization and stimulus discrimination? ©John Wiley & Sons, Inc. 2007 Huffman: Psychology in Action (8e)
Operant Conditioning: learning in which voluntary responses are controlled by their consequences Operant Conditioning ©John Wiley & Sons, Inc. 2007 Huffman: Psychology in Action (8e)
Thorndike’s Contribution Law of Effect: probability of an action being repeated is strengthened when followed by a pleasant or satisfying consequence Operant Conditioning (Continued) ©John Wiley & Sons, Inc. 2007 Huffman: Psychology in Action (8e)
Operant Conditioning (Continued) • B. F. Skinner ©John Wiley & Sons, Inc. 2007 Huffman: Psychology in Action (8e)
Operant Conditioning’s Basic Principles • Reinforcement:strengthening a response ©John Wiley & Sons, Inc. 2007 Huffman: Psychology in Action (8e)
Primary Reinforcers: normally satisfy an unlearned biological need(e.g., food) Secondary Reinforcers: learnedvalue (e.g., money, praise) Operant Conditioning’s Basic Principles (Continued) ©John Wiley & Sons, Inc. 2007 Huffman: Psychology in Action (8e)
Positive Reinforcement:adding (or presenting) a stimulus, which strengthens a response and makes it more likely to recur (e.g., praise) Operant Conditioning’s Basic Principles (Continued) ©John Wiley & Sons, Inc. 2007 Huffman: Psychology in Action (8e)
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) Operant Conditioning’s Basic Principles (Continued) ©John Wiley & Sons, Inc. 2007 Huffman: Psychology in Action (8e)
Operant Conditioning’s Basic Principles (Continued) ©John Wiley & Sons, Inc. 2007 Huffman: Psychology in Action (8e)
Operant Conditioning’s Basic Principles: Four Partial Schedules of Reinforcement 1. 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. 2007 Huffman: Psychology in Action (8e)
Operant Conditioning’s Basic Principles: Four Partial Schedules (Continued) 3. 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. 2007 Huffman: Psychology in Action (8e)
Operant Conditioning’s Basic Principles: Four Partial Schedules (Continued) ©John Wiley & Sons, Inc. 2007 Huffman: Psychology in Action (8e)
Pause and Reflect: Check & Review • If you want to increase the overall number of responses, which schedule of reinforcement should you choose? ©John Wiley & Sons, Inc. 2007 Huffman: Psychology in Action (8e)
Operant Conditioning’s Basic Principles (Continued) • Shaping: reinforcement is delivered after successive approximations of the desired response ©John Wiley & Sons, Inc. 2007 Huffman: Psychology in Action (8e)
Punishment:weakening a response Operant Conditioning’s Basic Principles (Continued) ©John Wiley & Sons, Inc. 2007 Huffman: Psychology in Action (8e)
Positive Punishment:adding (or presenting) a stimulus that weakens a response and makes it less likely to recur (e.g., shouting) Operant Conditioning’s Basic Principles (Continued) ©John Wiley & Sons, Inc. 2007 Huffman: Psychology in Action (8e)
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. 2007 Huffman: Psychology in Action (8e)
