PSYCH 1FF3 - Form Perception 1 & 2
UPDATED ACTUAL Questions and
CORRECT Answers
Gestalt principles - CORRECT ANSWER laws that describe how we organize visual input.
"the whole is other than the sum of its parts."
Figure-ground - CORRECT ANSWER ability to distinguish an object from its background in a
visual scene.
proximity - CORRECT ANSWER tendency to group elements that are close together in space.
closure - CORRECT ANSWER fill in gaps in a contour to perceive whole object.
similarity - CORRECT ANSWER group together elements that are physically similar
continuity - CORRECT ANSWER ability to percieve a simple, continuous form rather than a
combination of awkward forms.
common-fate - CORRECT ANSWER group elements that change in the same way.
Bottom-up (intuitive) - CORRECT ANSWER object recognition is guided by the features that are
present in the stimulus.
Top-down (cognition) - CORRECT ANSWER object recognition is guided by your own
beleifs/expectations.
Geon-theory - CORRECT ANSWER store numerous shapes in our mind.
,Template theory - CORRECT ANSWER we compare objects to templates in memory
1.if we can identify it, it came from our memory
2. if we can't, it is added to our memory
prototype theory - CORRECT ANSWER store ideal examples of an object (do not need exact
match)
Perceptual constancy - CORRECT ANSWER ability to perceive an object as unchanging even
though the visual image produced by the object is constantly changing.
shape - CORRECT ANSWER object is perceived to have a constant shape despite the shape of the
retina image changing with shifts in point of views/change in position.
location - CORRECT ANSWER stationary despite changing location on retina due to body
movements
size - CORRECT ANSWER same size despite size of retinal image varying with distance
brightness - CORRECT ANSWER same brightness despite reflecting more or less light onto our
retina
colour - CORRECT ANSWER have constant colour despite different illumination conditions
Muller-Lyer Illusion - CORRECT ANSWER A famous visual illusion involving the misperception
of the identical length of two lines, one with arrows pointed inward, one with arrows pointed outward.
misapplication of size
, Ames room illusion - CORRECT ANSWER A perceptual misinterpretation involving a trapezium
shaped room which appears rectangular when viewed through a peephole using only one eye and people
appear small or large, depending on where they stand in the room.
The Ames room manipulates size constancy because the two ends of the room are being perceived as the
same distance, which leads to perceiving the two individuals as being different sizes.
Visual cortex neuron - CORRECT ANSWER firing can be affected by:
1. location
2. orientation
3. direction of movement
Simple cell - CORRECT ANSWER responds maximally to a bar of a certain orientation in a
particular region of retina
Complex cell - CORRECT ANSWER Responds maximally to a bar of a certain orientation,
regardless of location. Some also respond maximally to a specific direction of movement.
hypercomplex cells - CORRECT ANSWER responds maximally to a bar of a particular orientation
and direction of movement, ending at specific points within the receptive field
cataract - CORRECT ANSWER disrupts light from passing through lens of eye
delayed removal correlates with increase in visual impairments.
Object agnosia - CORRECT ANSWER inability to recognize objects
Prosopagnosia - CORRECT ANSWER inability to recognize faces because they cannot integrate
the individual features of a face.
