What is Learning A process based on experience that results in a relatively permanent change in behavior or behavioral potential Classical Pavlovian Conditioning A Pavlov s observations experiment Classical conditioning occurs when one event or stimulus predicts the occurrence of another stimulus or event forming an association between 2 stimuli Studied a reflexive behavior salivation A stimulus that caused salivation food was paired with a neutral stimulus bell Eventually the bell produced the salivation as if dog anticipated the arrival of the food Classical Conditioning Terms 1 Before pairing a Neutral stimulus bell b Unconditioned stimulus UCS food c Unconditioned response UCR salivation 2 During pairing a Neutral stimulus paired with UCS b Unconditioned response UCR will occur because of the presence of the UCS 3 After pairing a Conditioned stimulus CS bell is no longer neutral b Conditioned response CR salivation B Details on the Demo Before conditioning Puff UCS Blink UCR Word neutral stimulus By pairing the puff and the word the word can come to produce Blink C Extinction Stop pairing the CS and UCS Eventually CS won t produce CR Classical Pavlovian Conditioning Behavior A Conditioned taste aversions B Conditioned Emotional Responses in Human 1 Watson Rayner 1920 Conditioned an 11 month old Little Albert to fear a white rat Rat neutral stimulus Loud noise UCS Startle fear UCR Pair the rat and the loud noise and the rat becomes the CS and the fear becomes the CR Results Little Albert generalized fear to other fuzzy things Watson Rayner didn t extinguish Little Albert s fear Watson had an affair with Rayner a student and was kicked out of the university 2 Other Conditioned Emotions a Post traumatic stress disorder PTSD Traumatic experiences can be elicited by sights sounds and smells that were neutral stimuli during battle Being shot at is a UCS which produces fear UCR If a sound e g helicopter is paired with being shot at the sound will become a CS that produces fear CR
