object agnosia
Inability to recognize objects using only vision.
top-down processing
a process whereby our existing knowledge of objects influences how we perceive them
bottom-up processing
a process whereby physical stimuli influence how we perceive them
recognition
the ability to match a presented item with an item in memory
representation
the storage and/or reconstruction of information in memory when that information is not in use
perceptual organization
the process by which multiple objects in the environment are grouped, allowing us to identify multiple
objects in complex scenes

grouping
the process by which elements in a figure are brought together into a common unit or object
Segregation
the process of distinguishing two objects as being distinct or discrete
figure-ground organization
the experience viewers have as to which part of an image is in front and which part of an image is in the
background of a particular scene
Gestalt Psychology
In terms of vision, gestalt argues that what we see is greater than its individual parts. That is, the process
of perception are designed to see the scene rather that bits of light here and there. Stimuli were
sufficiently rich in structure to allow the perceptual system to extract meaning directly from the stimuli
rather than building it up from an image of thought. The whole is different from the sum of its parts.
How symmetry and convexity affect figure-ground organization
Symmetry:
images that are more likely to be seen as figure and therefore in the foreground, whereas less
symmetrical images are more likely to be perceived as background
Convexity:
Images with convex borders are more likely to be seen as figure, whereas those with concave borders
are more likely to be seen as ground. (stevens and brookes 1988)

law of good continuation
grouping law stating that edges that are smooth are more likely to be seen as continuous than edges
that have abrupt or sharp angles
law of proximity
grouping law stating that elements that are close together tend to be perceived as a unified group
law of similarity
grouping law stating that elements that are similar to one another tend to be perceived as a unified
group
Law of Symmetry
grouping law stating that elements that are symmetrical to each other tend be be perceived as a unified
group
perceptual interpolation
the process by which the visual system fills in hidden edges and surfaces in order to represent the
entirety of a partially visible object
edge completion
the perception of a physically absent but inferred edge, allowing us to complete the perception of a
partially hidden object
illusory contours
