Psychology of Learning: Classical Conditioning Dr. K. A. Korb University of Jos Psychology of Learning Three Major Theories of Learning Dr. K. A. Korb University of Jos Behaviorism: Learning Behavior Cognitivism: Learning Knowledge Constructivism: Constructing Knowledge Outline Dr. K. A. Korb University of Jos Overview of Learning Theories Basics of Classical Conditioning Theories of Classical Conditioning Learning Definition: Relatively permanent change in behavior or knowledge as the result of experience. Dr. K. A. Korb University of Jos Relatively permanent: Knowledge or behavior must persist for some time Change: Alteration of previous behavior or knowledge Learning Definition: Relatively permanent change in behavior or knowledge as the result of experience. Dr. K. A. Korb University of Jos Behavior or Knowledge: New knowledge does not always affect behavior immediately Result of Experience: Experience with the environment or rational analysis Learning Theories Theory: Organized set of principles that describes, predicts, and explains phenomenon Dr. K. A. Korb University of Jos Describe: What happens Predicts: What will happen Explain: Why it happens Theories (Adapted from Driscoll, 2005) Make assumptions about knowledge Ask questions Conduct systematic observations Develop theory Compare results to theory Dr. K. A. Korb University of Jos Process of Theory Building Conduct research to test hypotheses Derive testable hypotheses Learning Theory Learning Theory: Proposes constructs linking observed changes in knowledge or behavior with what brings the changes Explain: Results: What changes are being explained? Means: What are the processes by which change occurs? Inputs: What triggers the process? Dr. K. A. Korb University of Jos What are the experiences that form the basis for learning? Criteria of Good Theories Dr. K. A. Korb University of Jos Logically sound Empirically sound Testable Parsimonious Learning Theories In order to master an art, one has to first master the theory and then one can master the practice. -E. Fromm Dr. K. A. Korb University of Jos World view Theories of learning Instructional theories, methods, strategies, motivation, assessment Lesson plans, etc. Day 4A Goal: Students develop an understanding of the relationship between world view, beliefs about learning and instruction, and the instruction that actually takes place. Materials: Powerpoint Readings for preparation: Driscoll chpts 1 & 9; Datnow & Castellano Procedure: Pose question, what determines what instruction will be like? (Schuh, 2008) Worldview Worldview: Framework of ideas and beliefs through which an individual interprets world Dr. K. A. Korb University of Jos Source of knowledge Correspondence between knowledge and the world Classical Conditioning (Pavlov, 1927) Dr. K. A. Korb University of Jos Classical Conditioning Before Conditioning Unconditioned Stimulus (food) Unconditioned Response (salivation) Neutral Stimulus (bell) No Conditioned Response (no salivation) During Conditioning Neutral Stimulus (bell) + Unconditioned Stimulus (food) Unconditioned Response (salivation) After Conditioning Conditioned Stimulus (bell) Dr. K. A. Korb University of Jos Conditioned Response (salivation) Law of Association Classical Conditioning Stimulus: Response: Event that activates a behavior Reaction to stimulus Unlearned/Involuntary Unconditioned Stimulus Unconditioned Response Neutral: Neutral Stimulus Unconditioned: No natural association Conditioned Learned by association Stimulus Conditioned: Dr. K. A. Korb University of Jos Conditioned Response Classical Conditioning Dr. K. A. Korb University of Jos Unconditioned Stimulus: Stimulus that triggers unconditioned response Unconditioned Response: Unlearned response to an unconditioned stimulus Neutral Stimulus: Stimulus that does not naturally elicit a response Conditional Stimulus: Neutral stimulus that comes to evoke a classically conditioned response Conditioned Response: Learned response to a classically conditioned stimulus Classical Conditioning Before Conditioning Unconditioned Stimulus (sugar) Unconditioned Response (salivate) Neutral Stimulus (finger in cup) No Conditioned Response (no salivation) During Conditioning Neutral Stimulus (sugar) + Unconditioned Stimulus (finger) Unconditioned Response (salivate) After Conditioning Conditioned Stimulus (finger in cup) Dr. K. A. Korb University of Jos Conditioned Response (salivate) Classical Conditioning Before Conditioning Unconditioned Stimulus (harsh reprimands) Unconditioned Response (fear) Neutral Stimulus (teacher) No Conditioned Response (no fear) During Conditioning Neutral Stimulus (teacher) + Unconditioned Stimulus (harsh reprimands) Unconditioned Response (fear) After Conditioning Conditioned Stimulus (teacher) Dr. K. A. Korb University of Jos Conditioned Response (fear) Classical Conditioning Before Conditioning Unconditioned Stimulus Unconditioned Response Neutral Stimulus No Conditioned Response During Conditioning Neutral Stimulus + Unconditioned Stimulus Unconditioned Response After Conditioning Conditioned Stimulus Dr. K. A. Korb University of Jos Conditioned Response Remember: The Response must be involuntary! Classical Conditioning and Attitudes Before Conditioning Unconditioned Stimulus (Father) Unconditioned Response (Like) Neutral Stimulus (TV show) No Conditioned Response (Neutral) During Conditioning Neutral Stimulus (TV show) + Unconditioned Stimulus (Father) Unconditioned Response (Like) After Conditioning Conditioned Stimulus (TV Show) Dr. K. A. Korb University of Jos Conditioned Response (Like) Classical Conditioning Dr. K. A. Korb University of Jos Theories of Classical Conditioning Substitution Theory (Pavlov) Contingency Theory (Rescorla) Dr. K. A. Korb University of Jos The conditioned stimulus becomes a substitute for the unconditioned stimulus Learning depends on the number of conditioned/unconditioned stimulus pairings Conditioned stimuli provides information about the likelihood of the unconditioned stimulus US: CS: US: CS: US: Dr. K. A. Korb University of Jos CS: Substitution Theory US: Almost no conditioning CS: US: CS: Dr. K. A. Korb University of Jos Good conditioning US: CS1: US: CS1: CS2: US: Dr. K. A. Korb University of Jos CS1: Substitution Theory Kamin Blocking: Failure of a stimulus to be associated with an unconditioned stimulus Dr. K. A. Korb University of Jos Occurs when a stimulus is presented with a previously learned conditioned stimulus Substitution Theory Dr. K. A. Korb University of Jos Summary: Learning is a function of the number of pairings between the CS and US Conclusion: Is not empirically sound Contingency Theory CS1 predicts the US Dr. K. A. Korb University of Jos Kamin Blocking: CS2 provides no additional information about the US Positive Contingency: CS predicts an increase in US Negative Contingency: CS predicts a decrease in US Zero Contingency: No learning Contingency Theory Summary: Learning occurs if the information value of the Conditioned Stimulus is high Classical Conditioning results from prediction, not association Dr. K. A. Korb University of Jos Law of Association Law of Prediction Classical Conditioning Factors that affect learning: Dr. K. A. Korb University of Jos Frequency with which the US and CS are paired Timing of the stimulus presentations Dr. K. A. Korb University of Jos Classical Conditioning US: CS: US: CS: US: CS: US: CS: US: CS: US: Dr. K. A. Korb University of Jos CS: Classical Conditioning Generalization: A similar conditioned stimulus elicits conditioned response Same Response Dr. K. A. Korb University of Jos Classical Conditioning Dr. K. A. Korb University of Jos Discrimination: A similar conditioned stimulus does not elicit a conditioned response Different Response Classical Conditioning Extinction: Conditioned stimulus no longer elicits conditioned response Occurs when conditioned stimulus occurs repeatedly without unconditioned stimulus During Conditioning Neutral Stimulus (bell) WITHOUT Unconditioned Stimulus (food) Unconditioned Response (salivation) After Conditioning Conditioned Stimulus (bell) Dr. K. A. Korb University of Jos Conditioned Response (salivation) Educational Implications Dr. K. A. Korb University of Jos Classical Conditioning relates most to learning of emotional behavior After repeated associations, previously neutral activities at school will become associated with emotions (happy, sad, anxious, angry, etc.) Educational Implications Pupil harassed at school Student has caring instructor Dr. K. A. Korb University of Jos Pupil feels bad when harassed Pupil associates being harassed and school Pupil feels bad when she thinks of school Student feels good when with instructor Student associates feeling good with the instructor Student feels good when he thinks of the instructor Student generalizes feeling good to school Learning Dr. K. A. Korb University of Jos Definition: Relatively permanent change in behavior or knowledge as the result of experience. Classical Conditioning Overview Dr. K. A. Korb University of Jos Results: Involuntary Responses Means: Prediction of US Inputs: Association of CS and US Classical Conditioning Overview Dr. K. A. Korb University of Jos Learning Outcomes: Involuntary reactions Role of the Learner: Passive Role of the Instructor: Provide an environment where education is associated with positive feelings Inputs for Learning: Association of CS and US Process of Learning: CS predicts US, resulting in CR Revision: Classical Conditioning Stimulus-Response Learning Dr. K. A. Korb University of Jos What is the definition of learning? What four criteria should each learning theory meet? Apply the process of classical conditioning to a novel situation (US, UR, CS, CR) Explain how classical conditioning works (Contingency Theory)
