1. Classical Conditioning – learn by association (pairing) by Pavlov : the dog saliva experiment Unconditioned Stimulus (UCS) – food Unconditioned Response (UCR) – salivate (in anticipation of the food) Conditioned Stimulus (CS) –bell (paired with food, UCS) Conditioned response (CR) –salivate Girl afraid of bridges UCS – fear-inducing talk UCR – fear CS – bridges (paired with UCS) CR - fear Examples of Classical Conditioning [things repeatedly paired with other things]: 1. Phobias – intense fear reaction to a situation (can also be treated with CC 2. Fetishism – sexual arousal when see something peculiar and stimulating (underwear hanging off the lamp) 3. Advertising – pairing product (CS) with good things (UCS) so consumers 2nd order conditioning : a neutral stimulus is paired to be a conditioned stimulus which is then associated with many other things. Ex: money. Acquisition: initial stage where the conditioned response is learned and gradually strengthened. Note: Neutral stimulus only works as a CS if it’s unusual or intense or new . Extinction: unlearn the CR by present CS without paring with UCS Spontaneous recovery : after extinction, CR (fear/saliva) comes back with the presence of CS (bridge/bell) without paring to UCS (fear-inducing talk/food), though not as strong as before, making it hard to do complete extinction. 1. Simultaneous conditioning: UCS and CS start and end together 2. Short-delayed conditioning (the most effective): CS begins and goes on for a while, UCS then is introduced while CS continues and they end together. 3. Trace conditioning (memory trace): CS starts and ends, then UCS starts Stimulus discrimination – precisely pick out/narrows down to a certain stimulus (time of the day, location, sound, smell) and ignore all the other stimulus Stimulus generalization – What Watson did to Little Albert, made him afraid of white fuzzy rats, fear is generalized to any white fuzzy things like bunnies and Santa Clause 2. Operant Conditioning – learn by consequences, trial-and-error

by Skinner Skinner’s Box experiment Positive Reinforcement (P RF) – ex: reward candy, smile Negative Reinforcement (N RF)– ex: don’t need to do chores Positive Punishment (P P)– ex: spanking, yelling Negative Punishment (N P) – ex: getting grounded, phone taken away Shaping : shape (train) the behavior with small steps to get closer and closer to end result by rewarding the behavior you want. Ex: pigeons play pingpong, train pets Stimulus control : only do something under certain circumstance (presence of other stimulus) ex: ask someone for a favor when you see he’s in a good mood Schedule of RF 1. Ratio schedules : reward when the behavior occurred 5 times 2. Interval schedules : reward on the last of every month Continuous RF –reward every time behavior occurs Intermittent RF –reward only sometimes irregularly . Much more powerful
