Learning Flashcards
Classical Conditioning
Neutral stimulus causes a formerly unrelated response if presented regularly just before another stimulus
Pavlov and his dogs
Unconditioned Stimulus
A stimulus that causes an innate response
Pavlov- food
Unconditioned Response
Natural reaction to stimulus
Pavlov- drooling when given food
Conditioned Stimulus
Stimulus paired with unconditioned stimulus to be given meaning/a response
Pavlov- bell paired with food
Conditioned Response
Learned response to conditioned stimulus
Generally same as unconditioned response
Pavlov- drooling when bell rung
Generalization
Similar stimuli gets the same response
Minute Bell Music
Discrimination
Ability to respond differently to similar stimuli
Someone is walking up stairs and being able to tell who it is
Extinction
Conditioned response dies out
Pavlov- Bell paired w/o food enough times that the dogs no longer drool
Spontaneous recovery
Conditioned response randomly comes back
Operant Conditioning
Learning from the consequences of behavior
Classical v operant
Smthn comes before vs smthn coming after
Shaping
Learning through little steps (successive approximation)
Reinforcement
Increases the chance that a behavior will occur again
Positive reinforcement
Pleasant stimulus presented following a response
Giving candy for good grades
Negative reinforcement
Unpleasant stimulus is withdrawn following a response
Fire alarm
Punishment
Decreases the chance that a behavior will occur again
Positive punishment
Response followed by unpleasant stimulus
Shock collar
Negative punishment
Response followed by removal of pleasant stimulus
Taking away phone
Primary reinforcer
Innate
food
Secondary reinforcer
Learned
Money
Ratio
Number of occurrences of behavior
Interval
Time between reinforcement
Fixed Ratio
Know how many times behavior has to occur before reinforcement
5 problems then a reward
Variable rato
Don’t know how many times behavior has to occur before reinforcement
