perceive object
compare to memory
identify object
deficits / impairments / diseases
agnosia
apperceptive agnosia
can't recognize objects
associative agnosia
can't recognize meaning of objects
intregative agnosia
can't combine parts into a whole
prosopagnosia (face blindness)
impaired ability to recognize familiar faces (including one's own face
computational approach
object’s image is projected on the retina
raw primal sketch
2.5D sketch

feature demon
cognitive demon
decision demon
naïve template / model bases identification theory
we recognize objects by matching it with their stored representations in our memory
structural decription
figure-ground theory
why do some parts of a picture appear to be in the background or foreground?
surroundings
size
symmetry
parallelism
extremal edges
relative motion
vertical - horizontal
meaningful objects
analytic vs. holistic thinking
analytic thinking: understanding a system's parts and how they work together to produce larger-scale effects
holistic thinking: understanding a system by sensing its large-scale patterns and reacting to them
