Learning and Classical Conditioning 19:47 What is learning? A relatively durable change in behavior or knowledge that is due to  experience Can be voluntary or involuntary Three types of learning/conditioning o Classical conditioning o Operant conditioning o Observational learning  Classical Conditioning (pavlovian) Form of learning in which a stimulus acquires the capacity to evoke a  response that was originally evoked by another stimulus Ivan Pavlov o The original study o Meat powder causes dog to salivate o Rang bell before giving meat powder Unconditioned association o This is when two things are naturally paired together o Unconditioned stimulus (meatpowder) A stimulus that evokes the unconditional response o Neutral stimulus (ringing of the bell) A stimulus that evokes no response o Unconditioned response (salivation)

An unlearned reaction to UCS (drooling meat powder) Conditioned association o This is when two things are paired/linked through conditioning/learning Conditioned stimulus (ringing the bell) A previously neutral stimulus that has, through conditioning,  acquired the capacity to evoke a conditioned response Conditioned response (drooling in response to bell) A learned response to a CS Dependent variable? Example 2 o Neutral stimulus: hearing a car door slam – no response o Unconditioned stimulus: mother yells at you – you cry o She slams the car door, you will cry Phobias and fear responses Pleasant emotions and physiological responses Acquisition – the initial stage of learning o Types of conditioning Simultaneous Pair ringing of bell and meat powder same time Trace Conditioning Get meat powder, then ringing of bell. Can be vice versa Short delay conditioning

Start ringing bell, half way through you give the meat powder o What pairing works best? Short delay seems to be best Extinction o The gradual weakening and disappearance of a Conditioned response Stimulus generalization o Occurs when a new stimulus that is similar to the original CS elicits similar  response (animal roars) o Stimulus discrimination o Occurs when a new stimulus that is similar to the original CS DOES not  elicit similar response  (car honking wont make you cry) (different bell wont  make you salivate) Sometimes a single conditional trial can lead to learning o Aversive conditioning Example: conditioned taste aversion (get sick while having mcdonalds,  you don’t want mcdonalds anymore)
