Chapter 5 Notes Learning I. What is learning? -learning is determined by maturation -Three types of learning (classical, conditioned and operant and conditioning) II. Classical Conditioning -Ivan Pavlov (1849- 1936) -Pavlov surgically inserted a tube into the dog’s mouth to measure amount Of saliva in a dogs produced -dogs would salivate at the sight of their food bowl, dog would hear a bell While they were eating, eventually the dog went from bell to saliva (Learned behavior) b.) Basic Elements of Classical Conditioning -Two events called stimuli pair and cause an association between the two -The NS (neutral stimulus) is presented (participant notices it but no reaction), and paired with an US (unconditioned stimulus), after the NS gets transformed into conditioned response *NS turns to CS, because it’s continually paired with US *pairing causes association between the two events able to predict -US automatically produces a reaction (ex: food=salvia) called the unconditioned response (UR)…UR’s are not learned they are equipped at birth -NS associated with the US transforms to a CS and gets a response for the UR; the response is a conditioned response (CR) -When CS elcits from CR=Classical conditioning c.) Classical Conditioning Processes -Acquisition -training stage where a particular response is learned -factors influence the acquisition of conditioned response -CS & US are presented, and the intensity of the US, and the number of times CS and US are paired - Sequence of CS-US presentation -optimum sequence is for the CS to precede the US (by 0.50 of a second) -US preceding the CS (backward conditioning) produce weaker conditioning, if any at all -the CS occurs after the US!! -Strength of the US -stronger the US the stronger the conditioning -Number of CS-US pairings- -the more the CS & US are paired the stronger the conditioning -Extinction

-present the CS without the US; see how long you can present the CS before the CR disappears Ex: Pavlov sounding metronome but giving no food, eventually the dogs will salivate less when the sound of the metronome -reduction and eventual disappearance of a behavior -Spontaneous Recovery -“forget” extinction has occurred -the CR recovers some of the strength it lost in extinction -amount of spontaneous recovery decreases day to day until response is Complete -Generalization and Discrimination -occurrence of responses to a stimuli that are SIMILAR to a CS Ex: fear of snakes if you see a rope of the ground you might jump In fear that it might be a snake -Discrimination- extinguished our fear, responses only to a specific CS -generalize makes you more likely to response, discrimination you response is appropriate to the stimulus and no other d.)
