Learning Chapter 7 Learning A relatively permanent behavior change due to experience Learning How do we learn? Conditioning – the process of learning associations Learning Classical Conditioning Classical Conditioning Learning Classical Conditioning Pavlov’s Experiments One of Pavlov's dogs, preserved at The Pavlov Museum Ryazan, Russia Classical conditioning–a type of learning in which one learns to link two or more stimuli and anticipate events. xxx Learning Classical Conditioning Major Phenomena Acquisition The initial stage of learning when a neutral stimulus is linked to an unconditioned stimulus so that the neutral stimulus begins triggering the conditioned response. Acquisition Extinction The diminished (weakened) responding that occurs when the conditioned stimulus no longer signals an upcoming unconditioned stimulus Extinction X Spontaneous Recovery The reappearance of a weakened conditioned response after a pause Generalization The tendency, once a response has been conditioned, for stimuli similar to the conditioned stimulus to elicit similar responses Discrimination The learned ability to discriminate between a conditioned stimulus and stimuli that do not signal an unconditioned stimulus Learning Classical Conditioning Extending Pavlov’s Understanding Biological Predispositions Courtesy of John Garcia John Garcia discovered that organisms are predisposed to learn associations that help them adapt and survive. Contrary to what many before Garcia believed, some associations are learned more readily than others. Biological Predispositions Learning Classical Conditioning Pavlov’s Legacy Applications of Classical Conditioning Credit: Psychonaught Former drug users often feel a craving when they are again in the drug-using context—with people or in places they associate with previous highs. Thus, drug counselors advise addicts to change environment. Applications of Classical Conditioning Former drug users often feel a craving when they are again in the drug-using context—with people or in places they associate with previous highs. Thus, drug counselors advise addicts to change environment. Applications of Classical Conditioning Advertisers pair previously neutral stimuli (brands) with erotic images with the idea that the brand will itself elicit the same positive response as the image. Classical conditioning is the basis of the adage that “sex sells.” Ad from April 1921 National Geographic Applications of Classical Conditioning Applications of Classical Conditioning As demonstrated by John Watson, emotional responses can be understood as developing through classical conditioning. Watson conditioned an 11-month old infant named “Little Albert” to fear white rats.
