PsychSmart INTRODUCTION TO PSYCHOLOGY 1 Copyright © McGraw-Hill, Inc. 2011 CHAPTER FIVE: LEARNING 2 Copyright © McGraw-Hill, Inc. 2011 Learning A relatively permanent change in behavior that is brought about by experience 3 Copyright © McGraw-Hill, Inc. 2011 Classical Conditioning What is learning? How do we learn to form associations between stimuli and responses? 4 Copyright © McGraw-Hill, Inc. 2011 What is Classical Conditioning? A type of learning in which a neutral stimulus comes to elicit a response after being paired with a stimulus that naturally brings about that response Ivan Pavlov 5 Copyright © McGraw-Hill, Inc. 2011 What is Classical Conditioning? Neutral stimulus Unconditioned stimulus (UCS) Unconditioned response (UCR) Conditioned stimulus (CS) Conditioned response (CR) Figure 1 of Chapter 5 Copyright © McGraw-Hill, Inc. 2011 6 How Do Conditioning Principles Apply to Human Behavior? “Little Albert” John B. Watson and Rosalie Rayner (1920) Phobias 7 Copyright © McGraw-Hill, Inc. 2011 Extinction of a Conditioned Response Occurs when a previously conditioned response decreases in frequency and eventually disappears Spontaneous Recovery Reemergence of an extinguished conditioned response after a period of rest and with no further conditioning 8 Copyright © McGraw-Hill, Inc. 2011 Extinction of a Conditioned Response Acquisition, Extinction, & Spontaneous Recovery in Classical Conditioning Figure 2 of Chapter 5 Copyright © McGraw-Hill, Inc. 2011 9 Generalization and Discrimination Stimulus Generalization Occurs when a conditioned response follows a stimulus that is similar to the original conditioned stimulus Stimulus Discrimination Occurs if two stimuli are sufficiently distinct from one another such that one evokes a conditioned response but the other does not 10 Copyright © McGraw-Hill, Inc. 2011 Operant Conditioning What is the role of reward and punishment in learning? What are some practical methods for bringing about behavior change—both in ourselves and in others? 11 Copyright © McGraw-Hill, Inc. 2011 Operant Conditioning Learning in which a voluntary response is strengthened or weakened, depending on its favorable or unfavorable consequences 12 Copyright © McGraw-Hill, Inc. 2011 How Operant Conditioning Works Reinforcement A process by which a stimulus increases the probability that a preceding behavior will be repeated Reinforcer Primary Secondary 13 Copyright © McGraw-Hill, Inc. 2011 How Operant Conditioning Works Positive Reinforcers Stimulus added to the environment that brings about an increase in a preceding response Negative Reinforcers Unpleasant stimulus whose removal leads to an increase in the probability that a preceding response will be repeated 14 Copyright © McGraw-Hill, Inc. 2011 How Operant Conditioning Works Punishment Stimulus that decreases the probability that a prior behavior will occur again Positive punishment Adding something Negative punishment Removing something 15 Copyright © McGraw-Hill, Inc. 2011 How Operant Conditioning Works Reinforcement and Punishment Figure 3 of Chapter 5 Copyright © McGraw-Hill, Inc. 2011 16 Schedules of Reinforcement Continuous reinforcement schedule Reinforced every time it occurs Partial (intermittent) reinforcement schedule Reinforced some but not all of the time 17 Copyright © McGraw-Hill, Inc. 2011 Schedules of Reinforcement Fixed-Ratio Schedule Reinforcement is given only after a specific number of responses. Variable-Ratio Schedule Occurs after a varying number of responses Figure 4 of Chapter 5 Copyright © McGraw-Hill, Inc. 2011 18 Schedules of Reinforcement Fixed-Interval Schedule Provides reinforcement for a response only if a fixed time period has elapsed Overall rates of response are relatively low. Variable-Interval Schedule The time between reinforcements varies based on an average rather than being fixed. 19 Copyright © McGraw-Hill, Inc. 2011 Discrimination and Generalization in Operant Conditioning Stimulus control training Behavior is reinforced in the presence of a specific stimulus, but not in its absence. Discriminative stimulus Signals the likelihood that reinforcement will follow a response 20 Copyright © McGraw-Hill, Inc. 2011 Shaping: Reinforcing What Doesn’t Come Naturally Process of teaching a complex behavior by rewarding closer and closer approximations of the desired behavior Animal training Complex human skills 21 Copyright © McGraw-Hill, Inc. 2011 Comparing Classical and Operant Conditioning Figure 5 of Chapter 5 Copyright © McGraw-Hill, Inc. 2011 22 Behavior Analysis and Behavior Modification Techniques Identify goals and target behaviors Design a data-recording system and record preliminary data Select a behavior-change strategy Implement the program Keep careful records after the program is implemented Evaluate and alter the ongoing program 23 Copyright © McGraw-Hill, Inc. 2011 Cognitive Approaches to Learning Can all learning be explained by operant and classical conditioning processes? What is the role of cognition and thought in learning? 24 Copyright © McGraw-Hill, Inc. 2011 Cognitive Learning Theory An approach that states that learning is best understood in terms of thought processes, or cognitions People develop an expectation that they will receive a reinforcer after making a response. 25 Copyright © McGraw-Hill, Inc. 2011 Latent Learning New behavior is learned but not demonstrated until some incentive is provided for displaying it. Learning occurs without reinforcement. 26 Copyright © McGraw-Hill, Inc. 2011 Observational Learning: Learning Through Imitation Learning by watching the behavior of another person, or model The social cognitive approach to learning Albert Bandura 27 Copyright © McGraw-Hill, Inc. 2011 Violence in Television and Video Games: Does the Media’s Message Matter? Recent research supports the claim that watching high levels of media violence makes viewers more susceptible to acting aggressively. 28 Copyright © McGraw-Hill, Inc. 2011 Does Culture Influence How We Learn? Relational learning style People master material best through exposure to a full unit or phenomenon. Analytical learning style People master material best when they can carry out an initial analysis of the principles and components underlying a phenomenon or situation. 29 Copyright © McGraw-Hill, Inc. 2011 Does Culture Influence How We Learn?
