obj recnition
agnosia
difficulty percieving obj features/drawing but can see simple features and meaning
can assog meaning to names
associative agnosia
can percieve simple features but cant assign meaning
describe apple but cant say this is an apple
recog obj
top down aka comcept/goal driven
relying on previous knowledge to id a stimuli
bottom up aka
recognisixing obj base on pattern
data driven/stimulus driven
recognition is linked to recognizing individual oarts
features are building blocks
proved through singe cell recording
maks role are to
stop a stimulus from being pricessed completly
words that are mroe common are mroe recognized
frequency effect
in rep primining uncommon words rpeform
poorly
first exposeure prin=mes for subsequent exposure
repititon priming
in rep priming, high requency words preform
not that much effect bc frequency priming takes over
word syperiority effecr
easier to recognize letters in words versus bythemselves
well formingness
easier it represents the languange, the mroe likely to recognize the word
feature net
fearure detecror–letterdect=== triggers higher level responce— word dector
frequent firit=ng results in
higher activation
why does reptition priming happen?
because recent firing results in a hiher activation
network includes a layer of
and do not need a higher level of input
bigram dectors
over recognization cmes from
feature net recovering from confusion
send feak activation to the bigram dectors
feature nrets contain
distrubuted knowledge
the mechien model emphasizes the role of
inhibitor measures
rbc model applies to recognition of
3d objects
what are gions
shapes for all 3d forms
