Learning Flashcards
Habituation
repeated exposure to a stimulus causes a decrease in response – lost sensitivity
Dishabituation: one becomes sensitive to stimulus again, recovery occurs from interruption of new stimulus or period of non-exposure
ASSOCIATIVE LEARNING
pairing of stimuli with stimuli, or response with behavior
– Classical and Operant Conditioning
Classical Condition
Neutral stimulus – doesn’t elicit a response
Unconditioned stimulus – doesn’t require learning, brings a reflexive response
Unconditioned response – the innate behavior
Conditional stimulus – previously neutral stimulus leads to desired response
Conditioned response – response caused by the conditioned stimulus
– the neutral stimulus must be associated with the unconditioned stimulus to elicit the same response
Pavlov’s dogs – associated bell with food, bell elicited drooling
Acquisition – stimulus-response pair becomes conditioned
Extinction – habituation to conditioned stimulus (bell without food – no more drooling)
Spontaneous recovery: emergence of previously habituated conditioned response
Discrimination – distinguish between similar stimuli – conditioned to a very specific conditioned stimulus
Generalization – broadening effect to similar stimuli
Operant Conditioning
REINFORCEMENT – behavior continues
PUNISHMENT – behavior stops
POSITIVE – stimulus added
NEGATIVE – stimulus removed
POSITIVE REINFORCEMENT – candy for doing homework
NEGATIVE REINFORCEMENT – no chores for doing homework
POSITIVE PUNISHMENT – time out for not doing homework
NEGATIVE PUNISHMENT – no TV time for not doing homework
Escape learning: reduce present unpleasantness
Avoidance learning: reduce future unpleasantness
Operant Conditioning – Reinforcement Schedules
VARIABLE RATIO: reward given after a RANDOM number of PERFORMANCES of the desired behavior – elicits the most frequent and robust behavior because the rat doesn’t learn how often to press the lever, just that he has to keep on pressing it for an eventual reward
FIXED RATIO: reward given after a DEINED number of PERFORMANCES of the desired behavior
VARIABLE INTERVAL: reward given after a RANDOM TIME interval if behavior occurred in that time frame
FIXED INTERVAL: reward given after a DEFINED time interval if the behavior occurred in that time frame
Latent Learning
learning occurs free of reward or incentive, but will be demonstrated once the possibility of reward arises
Preparedness
predisposition to a certain behavior
Instinctive Drift
overcoming an instinctive behavior
OBSERVATIONAL LEARNING
Modeling – emulating or copying learned behavior (bobo doll experiment)
Mirror Neurons – in the FRONTAL and PARIETAL LOBES, fire when they perform an action or see someone else perform an action
