Chapter 6: Learning
2
Classical Conditioning Ivan Pavlov Terminology –Unconditioned Stimulus (UCS) –Conditioned Stimulus (CS) –Unconditioned Response (UCR) –Conditioned Response (CR)
3
Figure 6.1 Classical conditioning apparatus
4
Figure 6.2 The sequence of events in classical conditioning
5
Figure 6.3 Classical conditioning of a fear response
6
Classical Conditioning: More Terminology Trial = pairing of UCS and CS Acquisition = initial stage in learning Stimulus contiguity = occurring together in time and space
7
Classical Conditioning: More Terminology 3 types of Classical Conditioning –Simultaneous conditioning: CS and UCS begin and end together –Short-delayed conditioning: CS begins just before the UCS, end together –Trace conditioning: CS begins and ends before UCS is presented
8
Processes in Classical Conditioning Extinction Spontaneous Recovery Stimulus Generalization Discrimination Higher-order conditioning
9
Figure 6.7 Acquisition, extinction, and spontaneous recovery
10
Figure 6.10 Higher-order conditioning
11
Operant Conditioning or Instrumental Learning Edward L. Thorndike (1913) – the law of effect B.F. Skinner (1953) – principle of reinforcement –Operant chamber –Emission of response –Reinforcement contingencies –Cumulative recorder
12
Figure 6.12 Reinforcement in operant conditioning
13
Figure 6.13 Skinner box and cumulative recorder
14
Basic Processes in Operant Conditioning Acquisition Shaping Extinction Stimulus Control –Generalization –Discrimination
15
Figure 6.14 A graphic portrayal of operant responding
16
Table 6.1 Comparison of Basic Processes in Classical and Operant Conditioning
17
Reinforcement: Consequences that Strengthen Responses Primary Reinforcers –Satisfy biological needs Secondary Reinforcers –Conditioned reinforcement
18
Schedules of Reinforcement Continuous reinforcement Intermittent (partial) reinforcement –Ratio schedules Fixed Variable –Interval schedules Fixed Variable
19
Figure 6.17 Schedules of reinforcement and patterns of response
20
Consequences: Reinforcement and Punishment Increasing a response: –Positive reinforcement = response followed by rewarding stimulus –Negative reinforcement = response followed by removal of an aversive stimulus Escape learning Avoidance learning Decreasing a response: –Punishment –Problems with punishment
21
Figure 6.18 Positive reinforcement versus negative reinforcement
22
Figure 6.19 Escape and avoidance learning
23
Figure 6.20 Comparison of negative reinforcement and punishment
24
Changes in Our Understanding of Conditioning Biological Constraints on Conditioning –Instinctive Drift –Conditioned Taste Aversion –Preparedness and Phobias Cognitive Influences on Conditioning –Signal relations –Response-outcome relations Evolutionary Perspectives on learning
25
Figure 6.22 Conditioned taste aversion
26
Observational Learning: Basic Processes Albert Bandura (1977, 1986) –Observational learning –Vicarious conditioning 4 key processes –attention –retention –reproduction –motivation acquisition vs. performance
