VERSIONS 2025
object agnosia - (answers)Inability to recognize objects using only vision.
top-down processing - (answers)a process whereby our existing knowledge of
objects influences how we perceive them
bottom-up processing - (answers)a process whereby physical stimuli influence
how we perceive them
recognition - (answers)the ability to match a presented item with an item in
memory
representation - (answers)the storage and/or reconstruction of information in
memory when that information is not in use
perceptual organization - (answers)the process by which multiple objects in the
environment are grouped, allowing us to identify multiple objects in complex
scenes
grouping - (answers)the process by which elements in a figure are brought
together into a common unit or object
Segregation - (answers)the process of distinguishing two objects as being distinct
or discrete
figure-ground organization - (answers)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 - (answers)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
,2|Page
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 -
(answers)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 - (answers)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 - (answers)grouping law stating that elements that are close
together tend to be perceived as a unified group
law of similarity - (answers)grouping law stating that elements that are similar to
one another tend to be perceived as a unified group
Law of Symmetry - (answers)grouping law stating that elements that are
symmetrical to each other tend be be perceived as a unified group
perceptual interpolation - (answers)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 - (answers)the perception of a physically absent but inferred
edge, allowing us to complete the perception of a partially hidden object
illusory contours - (answers)perceptual edges that exist because of edge
completion but are not actually physically present
recognition by components - (answers)a theory stating that object recognition
occurs by representing each object as a combination of basic units (geons) that
, 3|Page
make up that object; we recognize an object by the relation of its geons
Geons - (answers)the basic units of objects, consisting of simple shapes such as
cylinders and pyramids
viewpoint invariance - (answers)the perception that an object does not change
when an observer sees the object from a new vantage point
template theories - (answers)theories of pattern recognition which assert that
there is a mental representation for each of the patterns to be recognized
Area V4 - (answers)an area of the brain involved in both color vision and shape
perception
inferotemporal area - (answers)the area of the temporal lobe involved in object
perception; it receives input from V4 and other areas in the occipital lobe
fusiform face area - (answers)an area in the inferotemporal area of the temporal
lobe that specializes in recognizing familiar faces; located in the ventral surface of
the temporal lobe
occipital face area - (answers)an area of the brain in the occipital lobe, associated
with recognizing faces as distinct from other objects; located in the extrastriate
cortex and is strongly connected to the FFA
Prosopagnosia - (answers)inability to recognize faces but other forms of visual
object recognition are relatively intact. For example, a person with prosopagnosia
will have difficulty recognizing particular people but will not have difficulty
identifying roses or gloves.
Grill-Spector experiment - (answers)examined the role of the FFA in face
recognition using functional magnetic resonance imaging (fMRI) technology.
participants briefly saw Harrison Ford's face followed by a mask, or a control
stimulus followed by a mask (a). In (b), we can see the activity in the FFA when
the participant recognized the photo as Harrison Ford and when the participant
did not. Note that the highest response in the FFA is for correct recognition.
