exam three (memory) Flashcards
(48 cards)
skills, habits or behaviors
implicit learning
change in behavior over time in repsonse to a single stimulus (habituation or sensitization) is called
non associative learning
response decrease in nonassoc. learning
habituation
response increase in nonassoc. learning
sensitization
acquisition of new information
learning
rentention and retrieval of learned info
memory
learning procedure whereby a neutral stimulus comes to elicit a response because of its repeated pairing with some relevant event
pavlovian or classical conditioning
a stimulus that unconditionally- naturally and automatically- triggers a new response (salivating for food)
unconditioned stimulus
in pavlonian conditioning an originally neutral stimulus that, after association with an unconditioned stimulus triggers conditioned response (salivation to bell instead of food (natural))
conditioned stimulus
learning procedure in which the consequences of a particular behavior increase or decrease the prob. of the behavior occuring again
operant conditioning (instrumental)
compared to pavlovian/ classical , operant conditioning is
purposeful and goal-directed
what region of the brain does selection and initiation of “motivated movements”
the basal ganglia projects to area ___
6
area 6 (in cortex) projects back to
basal ganglia (forms a loop)
part of brain associated with procedural memory
striatum
the striatum is made up of what two structures
caudate nucleus and putamen
lesions to the striatum show what type of disruption
disruption to procedural memory
in the modified radial arm they use lighted arms to show where food is; this requires the ____ to pair the light arm with the food in that arm
striatum
as trials progress, cells in the striatum will fire less at the action directly proceeding the reward and instead striatum will fire at
beginning and end (shows mapping habit)
temporary information storage; requires rehearsal and has limited capacity
working memory
what brain region controls working memory
prefrontal cortex
in animals required to use working memory certain cells in the prefrontal cortex will fire throughout the delay in experiments, what happens to the cell firing when an error happens
the cell stops responding before the error occurs
the wisconsin card-sorting task shows that lesions to prefrontal cortex impair ability to change card sorting ____
strategy
area ____ in charge of saccades is also connected to working memory
LIP
