Learning and Memory Flashcards
habituation
when response to a stimulus is decreased after repeated exposure
dishabituation
recovery of a response to a stimulus after habituation has occurred; temporary and generally happens after a new stimulus has been presented
associative learning
creation of a pairing either between two stimuli or between a behavior and a response; two types are classical and operant conditioning
classical conditioning (acquisition)
type of associative learning that takes advantage of biological responses to create associations between two unrelated stimuli
unconditioned stimulus
stimulus that brings an innate, reflexive response
unconditioned response
innate or reflexive response
neutral stimuli
do not produce a reflexive response
signaling stimuli
neutral stimuli that has the potential to be used as a conditioning stimulus
conditioned stimulus
normally neutral stimulus that now causes a reflexive response
conditioned response
reflexive response from a normally neutral stimulus
extinction
when the conditioned stimulus has no more effect
spontaneous recovery
weak conditioned response when an extinct conditioned stimulus is presented
Generalization
a stimulus smilar enough to the conditioned stimulus can also produce the conditioned response
discrimination
organism learns to distinguish between two similar stimuli
operant conditioning
links voluntary behaviors with consequences in an effort to alter the frequency of these behaviors
behaviorism
theory that all behaviors are conditioned
reinforcement
process of increasing the likelihood that an individual will perform a behavior
positive reinforcer
increase a behavior by adding a positive consequence or incentive following desired behavior
negative reinforcer
increase the frequency of a behavior by removing something unpleasant
escape learning
role of the behavior is to reduce the unpleasantness of something that already exists
avoidance learning
behavior to prevent the unpleasantness of something that has yet to happen
primary reinforcer
positive reward that naturally elicits a response
conditioned (secondary) reinforcer
positive reward that does not naturally elicit a response; must be classically conditioned
discriminative stimulus
indicates that reward is potentially available in an operant conditioning paradigm
punishment
uses conditioning to reduct the recurrence of a behavior
positive punishment
adds an unpleasant consequence to reduct a behavior
negative punishment
reduction of a behavior when a stimulus is removed
fixed-ratio schedules
reinforce a behavior after a specific number of performances of that behavior
continuous reinforcement
behavior is rewarded every time it is performed
variable-ratio schedules
reduce a behavior after a varying number of performances of the behavior, but such that the average number of performances to receive a reward is relatively constant (works best)
fixed-interval schedules
reinforce the first instance of a behavior after a specified time period has elapsed
variable-interval schedules
reinforce a behavior the first time that behavior is is performed after a varying interval of time
shaping
rewarding increasingly specific behaviors
latent learning
learning that occurs without a reward but that is spontaneously demonstrated once a reward is introduced
