PSYC 230 UIUC EXAM 3 CONTAINING A FULL SET OF QUESTIONS AND VERIFIED
ANSWERS FOR STUDENTS PURSUING PSYCHOLOGICAL SCIENCE
ANSWER The inability to identify items solely by sight is known as object
agnosia.
Top-down processing is the process by which our preexisting understanding of
an object shapes our perception of it.
Bottom-up processing is the process by which our perceptions of physical
stimuli are influenced.
The ability to match an item in memory with one that is presented is known as
recognition.
representation: the act of storing and/or reconstructing data in memory while it
is not being used
The process by which several elements in the environment are grouped together
to enable us to recognise several objects in intricate settings is known as
perceptual organisation.
The process by which components in a figure are combined to form a single unit
or object is known as grouping.
The process of identifying two objects as distinct or discrete is known as
segregation.
Figure-ground organisation is the perception that viewers have of which areas
of an image are in front of and which are behind a specific scenario.
Gestalt Psychology - ANSWER Gestalt theory of vision holds that our
perception is more comprehensive than the sum of its parts. In other words, the
vision process is made to see the scene rather than sporadic glimmers of light.
The structure of the stimuli was rich enough that the perceptual system could
derive meaning from them directly, without having to construct it from a mental
representation. The sum of its pieces does not equal the whole.
, How figure-ground organisation is impacted by symmetry and convexity
ANSWER Symmetry:
less symmetrical images are more likely to be viewed as background, while
more symmetrical images are more likely to be seen as figures and hence in the
forefront.
Convexity
Convex images are more likely to be interpreted as figures, while concave
images are more likely to be seen as ground. In 1988, Stevens and Brookes
The ANSWER grouping law, known as the law of good continuation, is that
edges with smooth angles are more likely to be perceived as continuous than
those with abrupt or sharp angles.
The ANSWER grouping law, known as the law of proximity, states that things
that are near one another are more likely to be viewed as a single entity.
According to the ANSWER grouping law, items that are similar to one another
are more likely to be viewed as a single, cohesive group.
The Law of Symmetry is an ANSWER grouping law that states that
symmetrical elements are more likely to be viewed as a single, cohesive group.
The process by which the visual system completes the representation of a
partially seen object by filling in hidden edges and surfaces is known as
perceptual interpolation.
Edge completion enables us to finish perceiving a partially hidden item by
answering the perception of a physically absent but inferred edge.
Illusory contours: ANSWER perceived edges that are not physically present but
exist due to edge completeness
According to the theory of recognition by components, each item is represented
as a collection of fundamental units (geons) that comprise it; we can identify an
object based on the relationship between its geons.
Geons are the fundamental building blocks of objects, which include basic
shapes like pyramids and cylinders.
The idea that an object remains unchanged when viewed from a different angle
is known as perspective invariance.
