Classical Conditioning Learning Classical Conditioning
Classical Conditioning How do you know when you are hungry? How do you feel when you smell a rose? Classical conditioning is when you shape a behavior gradually over time, controlling an old response to new stimuli
Neutral Stimulus An object/stimulus that has no association to the desired response
Unconditioned Stimulus UCS: an event that leads to a certain predictable response without previous training
Unconditioned Response UCR: a response that occurs naturally and automatically when the UCS is presented
Conditioned Stimulus/ Conditioned Response CS: An ordinarily neutral event that leads to a desired response after training CR: a learned response to a stimuli
Generalization Response to a similar stimuli, but not the CS, without prior training
Discrimination Learning to respond differently to different stimuli
Extinction When the conditioned response, CR, no longer occurs when the neutral stimuli is presented
Pavlov Russian Scientist studying digestion Discovered Classical Conditioning Experimented using dogs
A Different Approach
Watson and Albert Psychologist Watson used classical conditioning on an infant who was orphaned Baby albert was conditioned to be frightened of rats Albert generalized that fear to all white fuzzy things Albert was never conditioned to discriminate, nor did Watson try to extinguish the behavior before Albert left the study.
