Recognizing Objects
-
Top down processing
concept driven, knowledge effects
-
Word Superiority effect
people’s response
when asked whether “DARK” has an “E” or a “K”
is faster than when searching within a letter
string such as “JPERW
-
Bottum Up processing
data driven, stimulus driven effects
integrative agnosia
parietal cortex damage,Disruption of parietal cortex via transcranial magnetic stimulation (TMS), difficulty in judging how more than one feature bound together in objects
neural Network
With input, activation level increases,
Have receptive fields, Fire above threshold,
Complex assemblies of neurons
-
Bigram detectors, word detectors, feature detectors, letter detectors, stimulus input
-
Holistic processing measures the
Composite faces
Features matter but
cannot be considered
individually
The relationships
guide face recognition
