Test 2: Learning & Memory Flashcards
(74 cards)
Learning
relatively permeant change in behavior (knowledge, skills) due to experience
3 types of learning
classical conditioning, operant conditioning, social learning
classical conditioning
neutral stimulus is associated with a neutral response
operant conditioning
response is increased/decreased due to reinforcement or punishment
social learning
how we learn by observing the behavior of others
why its important to study learning
modify behavior, treating behavior disorders (phobias)
forward conditoning
CS becomes reliable predictor of US
backward conditioning
CS has no predictive value, US occurs before CS
generalize
respond in similar way to stimuli similar to CS
discrimination
ability to distinguish between stimuli
law of effect
behaviors that lead to positive outcomes tend to be repeated, Thorndike’s puzzle box
problems of punishment as form of reinforcement
learned fear, encourages aggression, only indicates what not to do
chaining
reinforcement of successive steps to final desired behavior
intermittent reinforcement effect
if you learn to expect variance you will expect variance, if you learn there is not variability you will expect none
Interval
based on time
ratio
based on number of responses
continuous
reinforcement for every response
fixed ratio
reinforcement following completion of specific number of responses
variable ratio
reinforcement for an unpredictable number of responses
fixed interval
reinforcement over fixed time (paycheck)
variable interval
reinforcement for an unpredictable delay
reinforcement continuously leads to
faster learning but faster extinction
reinforcement intermittently
slower learning but more resistant to extinction
memory
ability to store and retrieve information over time
