Q

frequent firit=ng results in

A

higher activation

14
Q

why does reptition priming happen?

A

because recent firing results in a hiher activation

15
Q

network includes a layer of
and do not need a higher level of input

A

bigram dectors

16
Q

over recognization cmes from

17
Q

feature net recovering from confusion

A

send feak activation to the bigram dectors

18
Q

feature nrets contain

A

distrubuted knowledge

19
Q

the mechien model emphasizes the role of

A

inhibitor measures

20
Q

rbc model applies to recognition of

21
Q

what are gions

A

shapes for all 3d forms

22
this is the feature net for 3s obj, explain their fx feature dectors geon dectors geon asseblies obj model
feature dectors: curves edges geon dectors: basic 3d shape dector geon asseblies: relationship between geons like top vs side obj model: complete picture
23
mukltiple vies model, rnb
mental rotation is required, recognition is viewing angle is dependant
24
hiarchy of rmv movel vs others, what is the difference? whole obj corners/notches lines/orientations
this rebrens a particualr viewpoint and obj specific vs a part of the obj,
25
prosopagnosia
face blindness, knoes i is a face doesnt know whose face it is
26
it is the relationships but not the features alone that guide facialr ecognition
composite effect
27
activation in the back of the brain indicates
