Development and Learning Domain
Learning A relatively permanent change in behavior caused by experience. Experience Practice Adapt Associate Sequence
Classical Conditioning Module 14 Classical Conditioning
A strategy for remembering… Unconditioned = Natural Conditional = Learned
Classical Conditioning A type of learning in which a stimulus gains the power to cause a response. The stimulus predicts another stimulus that already produces that response Form of learning by association
Stimulus-Response Stimulus - anything in the environment that one can respond to. Response – any behavior or action.
Stimulus-Response Relationship
Stimulus-Response Relationship
Ivan Pavlov (1849-1936) Russian physiologist and learning theorist famous for discovery of classical conditioning, in which learning occurs through association.
Pavlov’s Research Apparatus
Pavlov’s Experiment
Acquisition The process of developing a learned response. The subject learns a new response (CR) to a previously neutral stimulus (CS)
Generalization Producing the same response to two similar stimuli. The more similar the substitute stimulus is to the original used in conditioning, the stronger the generalized response
Extinction In classical conditioning, the diminishing of a learned response after repeated presentation of the conditioned stimulus alone. In classical conditioning, the continual presentation of the CS without the UCS
Discrimination The ability to distinguish between two signals or stimuli and produce different responses. The subject learns that one stimuli predicts the UCS and the other does not.
John Watson Founder of behaviorism, the theory that psychology should restrict its efforts to studying observable behaviors, not mental processes
Little Albert 11-month-old infant Watson and Rosalie Rayner, conditioned Albert to be frightened of white rats..PHOBIA? Led to questions about experimental ethics
Little Albert – Before Conditioning
Little Albert – During Conditioning
Little Albert – After Conditioning
Little Albert - Generalization
Can you reverse conditioned fear? Systematic Desensitization Mary Cover Jones
What happened to little Albert? Little Albert was really Douglas Merritte Child of Arvilla Irons Died of brain disorder (Hydrocephalus) when he was six-years old For more information: http://www.youtube.com/watch?v=MIc9ijXukho
Cognition and Biological Predispositions Module 14: Classical Conditioning
Cognition All mental processes associated with thinking, knowing, and remembering. What effect does cognition have on learning?
Robert Rescorla (1940- ) a theory that emphasized the importance of cognitive processes in classical conditioning. Pointed out that subjects had to determine (think) whether the CS was a reliable predictor of the UCS
The inability to learn new responses Martin Seligman Learned Helplessness? The inability to learn new responses
Taste Aversion Subjects become classically conditioned to avoid specific tastes, because the tastes are associated with nausea. John Garcia (1917- ) Limitations of classical conditioning?
