the ability to match a presented item with

organizing into groups grouping

the whole is greater than the sum of its

parts
allows you to recognize and organize ob-
perceptual organization
jects: grouping, segregation
distinction between foreground and
figure-ground organization
background
figures with edges that are smooth are
law of good continuation
seen as continuous
elements close to one another tend to be
law of proximity
perceived as a unit
How symmetry and convexity affect fig-

objects that are similar tend to be
law of similarity
grouped together
things are grouped in common regions

the perception of a partially absent but
inferred edge, allowing us to complete edge completion
perception of a partially hidden object
imagined "boundaries" between one ob-
ject and other; often created by the per-
illusory contours
ception of "lines" that divide areas of col-
or or texture
previous knowledge and experience with
objects forever changes the way we per-
how knowledge shapes perception
ceive and identify those objects in the
future - helps with seeing edges
basic component of an object, 2d or 3d
geons
forms
the ability to recognize an object seen
viewpoint invariance
from different viewpoints
its not fool proof problems with viewpoint invariance
point-by-point comparison to a stored
template theories
"average or ideal" representation
multiple stored representations with all
possible variations - takes up a lot of problems with template theories
memory space
representation of shapes in the brain area v4
object recognition inferotemporal lobe
temporal lobe, responded to faces that
fusiform face area
are already known
occipital lobe, responds to face-like im-
face recognition
ages
inability to recognize faces prosopagnosia
stimulus -> mask -> observers response the grill-specter experiment
area in temporal lobe for scene recogni-
parahippocampal place area (PPA)
