The Adaptive Mind Chapter 8 Learning –What is learning? –Nonassociative learning –Habituation/Sensitization Agenda –Associative Learning –Classical conditioning –Operant conditioning –Observational learning What is learning? – A relatively permanent change in behavior due to experience – Changes are stable – Change in behavior – Due to experience How do animals respond to their environments? – Reflexes – Instincts – Learned behaviors Stimulus: Anything that elicits a response/reaction Response: The behavior that occurs in the presence of a stimulus Reflexes – Inevitable, involuntary response to stimuli – Controlled by nervous system circuits – Fast, automatic, inflexible Instincts – An inborn pattern of behavior elicited by environmental stimuli – Fixed action pattern – More complex than reflexes – Once they begin, they run until completion Three Types of Learning Learning Nonassociative Associative Observational learning learning Learning Habituation Sensitization Classical Operant conditioning conditioning üWhat is learning? –Nonassociative learning –Habituation/Sensitization Agenda –Associative Learning –Classical conditioning –Operant conditioning –Observational learning Nonassociative Learning – Learning that involves changes in the magnitude of responses to a stimulus – Two important types: – Habituation – Sensitization Habituation – Reactions to repeated stimuli that are unchanging and harmless decrease – Occurs in response to milder stimuli Habituation vs. Sensory Adaptation – Sensory Adaptation = Tendency to pay less attention to a nonchanging source of stimulus (sensation and perception) – Habituation = A simple form of learning in which reactions to repeated stimuli that are unchanging and harmless decrease 12 Sensitization – An increased reaction to many stimuli following exposure to one strong stimulus – Occurs in response to stronger stimuli üWhat is learning? üNonassociative learning üHabituation/Sensitization Agenda –Associative Learning –Classical conditioning –Operant conditioning –Observational learning Associative Learning – The formation of associations, or connections, among stimuli and behaviors – Two important types: – Classical conditioning – Operant conditioning Unconditioned: Something that occurs without learning (reflexive) Conditioned: Something that must be learned Classical Conditioning – Associations are formed between two stimuli that occur sequentially in time Classical conditioning Unconditioned Conditioned UCS CS Elicits a response Elicits a response after Stimulus reflexively, being learned through without prior experience experience UCR CR A learned behavior A reflexive behavior Response following a stimulus, following a stimulus, requires prior requires no prior experience experience Classical conditioning phenomena Acquisition: development of a learned response (CR) Classical conditioning phenomena Acquisition: development of a learned response (CR) §Contiguity: CS must occur before UCS and close together in time Classical conditioning phenomena Acquisition: development of a learned response (CR) §Contiguity: CS must occur before UCS and close together in time...... Classical conditioning phenomena Acquisition: development of a learned response (CR) §Contiguity: CS must occur before UCS and close together in time §Contingency: CS and UCS must reliably occur together Classical conditioning phenomena Extinction: reduction of a learned response (CR) – CS is presented repeatedly without the UCS Acquisition (CS+UCS) Extinction (CS only) Classical conditioning phenomena Extinction: reduction of a learned response (CR) – Spontaneous recovery: the reappearance of conditioned responses (CRs) after periods of rest Acquisition (CS+UCS) Extinction (CS only) Classical conditioning phenomena Inhibition: A conditioned stimulus (CS) predicts the nonoccurrence of an unconditioned stimulus (UCS) – The CS predicts that the UCS will NOT occur Classical conditioning phenomena Latent inhibition: A familiar CS à slower (later) learning An unfamiliar CS à quicker (immediate) learning Classical Conditioning Phenomena Generalization: The tendency to respond to neutral stimuli that are similar to an original conditioned stimulus Classical Conditioning Phenomena Discrimination: A learned ability to distinguish between stimuli Classical Conditioning Phenomena Classical Conditioning Phenomena Higher-order conditioning A stimuli + A conditioned stimulus à Conditioned responses Watson’s Experiment with Little Albert (1920) Give me anyone, and I can make them into anything “Give me a dozen healthy infants, well-formed, and my own specified world to bring them up in and I’ll guarantee to take any one at random and train him to become any type of specialist I might select — doctor, lawyer, artist, merchant- chief and, yes, even beggar-man and thief, regardless of his talents, penchants, tendencies, abilities, vocations, and race of his ancestors.” –John Watson, Behaviorism, 1930 Cognitive and biological influence on classical conditioning – Early behaviorists – Advocate the roles of nurture (vs. nature) – Only focus on studying external behaviors – Believed that behavior followed the same rules in all organisms – ? Rats à Humans The element of surprise! – Learning takes place more quickly when the association between the CS and the UCS is relatively surprising and unexpected. Applications of classical conditioning –Overcoming fear – Exposure therapy –Addiction treatment – Unpairing CS and CR Applications of classical conditioning –Overcoming fear – Exposure therapy –Addiction treatment –Advertising Applications of classical conditioning –Overcoming fear – Exposure therapy –Addiction treatment –Advertising –Development of prejudice – Latent inhibition üWhat is learning? üNonassociative learning üHabituation/Sensitization Agenda –Associative Learning üClassical conditioning –Operant conditioning –Observational learning Thorndike’s Law of Effect – Behaviors that are followed – Behaviors that are followed by something pleasant are by something unpleasant more likely to be repeated are less likely to be repeated Operant Conditioning – Associations are formed between behaviors and their consequences – Organisms operate in their environments Classical conditioning Operant conditioning An association between 2 A behavior is associated stimuli with its consequences Behaviors that are often Behaviors that are active, subconscious and not intentional, and voluntary voluntary B.F. Skinner and the “Skinner Box” Types of Consequences – Positive = ADDING a stimulus – Doesn’t mean “good” – Negative = SUBTRACTING a stimulus – Doesn’t mean “bad” Types of Consequences Reinforcement: A consequence that increases the likelihood of a behavior – Positive Reinforcement: Adding something desirable to increase the frequency of a behavior – Negative Reinforcement: Taking away something unpleasant to increase the frequency of a behavior Types of Consequences Punishment: A consequence that decreases the likelihood of a behavior – Positive Punishment: Adding something unpleasant to decrease the frequency of a behavior – Negative Punishment: Taking away something pleasant to decrease the frequency of a behavior Types of Consequences Reinforcement Punishment Increases the likelihood decreases the likelihood of a behavior of a behavior Positive (+) Add a pleasant Add an unpleasant Something is outcome outcome offered Negative (-) Remove an Remove a pleasant Something is unpleasant outcome outcome taken away More on Punishment – Effective punishments are… – Significant – Consistent – Immediate Schedules of Reinforcement Continuous Reinforcement: Reinforce behaviors every time they occur Partial Reinforcement: Reinforce behavior on some occasions, but not all – Ratio Schedule: Depends on the number of times a behavior occurs – Interval Schedule: Depends on the passage of a certain amount of time Ratio Schedules of Reinforcement Fixed ratio: Reinforcement follows a set number of behaviors Variable ratio: Reinforcement follows a variable number of behaviors Interval Schedules of Reinforcement Fixed interval: The first response following a specified interval is reinforced (e.g. every 5 mins) Variable interval: The first response following a varying period is reinforced (e.g. every 3-7 mins) Choosing a Reinforcement Schedule What is the basis of reinforcement? Is the schedule set/regular Behavior Time or changing? Fixed Fixed Set Ratio Interval Variable Variable Changing Ratio Interval Effectiveness of Reinforcement Schedules Shaping – The method of successive approximations – Used to increase the frequency of behaviors that never or rarely occur Applications of Operant Conditioning – Parenting! – Training your pets! – Token economies – Tokens that you earn can be exchanged for other reinforcers – Used to increase the frequency of desired behaviors – Commonly used in schools and institutional settings (mental health facilities) üWhat is learning? üNonassociative learning üHabituation/Sensitization Agenda üAssociative Learning üClassical conditioning üOperant conditioning –Observational learning Observational Learning – Learning that occurs when one organism watches the actions of another organism – Social learning/modeling – Similar to imitation – Many behaviors are influenced by observation: – Aggression – Language development – Moral judgement Processes of Observational Learning 1. Attention: More likely to imitate attention-grabbing things 2. Retention: Maintain a memory 3. Reproduction: Be able to imitate model 4. Motivation: Must be motivated to imitate a behavior üWhat is learning? üNonassociative learning üHabituation/Sensitization Agenda üAssociative Learning üClassical conditioning üOperant conditioning üObservational learning Development Chapter 3 and 11  Great Debates  Newborn Development Agenda  Infancy & Childhood Development  Adolescent Development  Adult Development Nature vs. Nurture?

It was a form of radium that a druggist in the same town had recently discovered.The drug was expensive to make, but the druggist was charging 10 times what the drug cost him to make. He paid $200 for the radium and charged $2,000 for a small dose of the drug.The sick woman’s husband, Heinz, went to everyone he knew to borrow the money, but he could get together only about $1,000, which was half of what it cost. He told the druggist that his wife was dying and asked him to sell it cheaper or let him pay later. But the druggist said, “No, I discovered the drug and I’m going to make money from it.” Heinz got desperate and broke into the man’s store to steal the drug for his wife.
