ACTUAL EXAM 170 QUESTIONS AND CORRECT
DETAILED ANSWERS (VERIFIED ANSWERS)
ALREADY GRADED A+
object agnosia -CORRECT ANSWER Inability to recognize
objects using only vision.
top-down processing -CORRECT ANSWER a process whereby
our existing knowledge of objects influences how we perceive
them
bottom-up processing -CORRECT ANSWER a process whereby
physical stimuli influence how we perceive them
recognition -CORRECT ANSWER the ability to match a
presented item with an item in memory
representation -CORRECT ANSWER the storage and/or
reconstruction of information in memory when that information is
not in use
,perceptual organization -CORRECT ANSWER the process by
which multiple objects in the environment are grouped, allowing
us to identify multiple objects in complex scenes
grouping -CORRECT ANSWER the process by which elements
in a figure are brought together into a common unit or object
Segregation -CORRECT ANSWER the process of distinguishing
two objects as being distinct or discrete
figure-ground organization -CORRECT ANSWER 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 -CORRECT ANSWER 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 -
CORRECT ANSWER 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 -CORRECT ANSWER 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 -CORRECT ANSWER grouping law stating that
elements that are close together tend to be perceived as a unified
group
law of similarity -CORRECT ANSWER grouping law stating that
elements that are similar to one another tend to be perceived as a
unified group
, Law of Symmetry -CORRECT ANSWER grouping law stating
that elements that are symmetrical to each other tend be be
perceived as a unified group
perceptual interpolation -CORRECT ANSWER 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 -CORRECT ANSWER the perception of a
physically absent but inferred edge, allowing us to complete the
perception of a partially hidden object
illusory contours -CORRECT ANSWER perceptual edges that
exist because of edge completion but are not actually physically
present
recognition by components -CORRECT ANSWER a theory
stating that object recognition occurs by representing each object
as a combination of basic units (geons) that make up that object;
we recognize an object by the relation of its geons
Geons -CORRECT ANSWER the basic units of objects,
consisting of simple shapes such as cylinders and pyramids
