NEU223 Chapter 9 cont (PRIMING)

priming

changes in response to a stimulus

declarative memory

you arent aware of being primed

normally, when u see a bike from an odd angle, you take ___ time to identify it

more

when primed, when u see a bike from an odd angle, you take ___ time to identify it

less

perceptual representation system/prs

structure and form of objects/words are primed by prior experience

word fragment completion task

if shown flashcard w/ the word thoughts beforehand, it would be easier to complex the task than if you didnt see it before

effects of priming depend on the type of

stimulus

words as a stimulus

shorter, 2 min

pictures as a stimulus

longer, 48 weeks

pt hm

showed evidence of priming even tho he claimed to never see the word before

pt hm’s evidence of priming shows that the prs does not

rely on mtl

picture naming paradigm tests

effects of priming on amnesiac w/ hippocampus damage

double dissociation

can damage 1 but not the other

when doing the picture naming paradigm, amnesiacs are

faster at naming previously seen pictures even after 1 week

pt ms

had severe amnesia bc right occipital lobe removed, no priming effect, no problem recognizing words

test for explicit memory

recognition, cued recall

test on implicit memory

perceptual priming

perceptual priming can be damaged but

explicit memory is not

implicit memory task

new/previous words seen in a perception test shown briefly, then ppl had to identify word at increasing durations until they could identify it

recognition task

2 weeks later, ppl shown 10 words seen b4, 10 words never seen b4

classical conditioning

grad students gave food to dogs, every time they came in bell rang, dogs salivated

unconditioned =

unlearned

us

food

ur

salivation

ns

bell before conditioning

cs

bell after pairing w/ food

cr

salivation response to bell

delay conditioning

cs overlaps w/ us

trace conditioning

time gap between cs and us, memory required

hippocampus controls

trace conditioning, learning, memory

nonassociative learning

does not involve association of stimuli to make a response

habituation

response to unchanging stimulus decreases over time

sensitization

response increases w/ repeated presentations of the stimulus

example of sensitization
