PSYC 230 UIUC UPDATED EXAM ACTUAL QUESTIONS AND
ANSWERS SURE A+
✔✔binocular disparity - ✔✔a binocular depth cue because our two eyes are in different
locations in our head and therefore have slightly different views of the world
✔✔three-dimensional movies - ✔✔allows stereoscopic vision to occur
✔✔Horopter - ✔✔the region in space where the two images from an object fall on
corresponding locations on the two retinae
✔✔corresponding points - ✔✔refers to a situation in which a point on the left retina and
a point on the right retina would coincide if the two retinae were superimposed
✔✔noncorresponding points - ✔✔refers to a situation in which a point on the left retina
and a point on the right retina would not coincide if the two retinae were superimposed
✔✔Panum's area of fusion - ✔✔the region of small disparity around the horopter where
the two images can be fused into a single perception
✔✔diplopia - ✔✔double images, or seeing two copies of the same image; usually
results from the images of an object having too much disparity to lead to fusion
✔✔stereogram - ✔✔a picture that uses the principle of binocular disparity to create the
perception of a three-dimensional image
✔✔anaglyph - ✔✔another form of stereogram and the techniqie generally used in
recent 3D movies. Use a pair of anaglyph glasses to look at these images (red and blue
framed glasses)
✔✔random dot stereogram - ✔✔A stereogram in which both images consist of a grid of
randomly arranged black and white dots, identical except for the displacement of a
portion in one image relative to the other; an observer who views a random dot
stereogram in a stereoscope or as an anaglyph will see a single image with the
displaced portion in depth
✔✔random-dot stereograms as anaglyphs - ✔✔use a pair of anaglyph glasses to
examine the image. you should see patterns floating in front of the pattern of black and
white dots
✔✔virtual reality - ✔✔the computer-generated photograph, image, or environment that
can be interacted with an apparently real way
✔✔Forced perspective and illusions - ✔✔our preconceptions/assumptions being defied
, ✔✔binocular cells - ✔✔Cells with two receptive fields, one for each eye; their main
function is to match the images coming to each eye
✔✔size-distance invariance - ✔✔the relation between perceived size and perceived
distance: the perceived size of an object depends on its perceived distance, and vice
versa
✔✔size constancy - ✔✔the perception of an object as having a fixed size, despite the
change in the size of the visual angle that accompanies changes in distance
✔✔Ponzo illusion - ✔✔the illusion in which two horizontal lines are drawn one above
the other; both lines are on top of two inwardly angled vertical lines; the top line, where
the two vertical lines are closer together
✔✔Muller-Lyer Illusion - ✔✔the illusion where a line that has two lines going at an angle
looks longer than a line of the same length but the end lines angle back across the main
line
✔✔Ames room illusion - ✔✔a specially constructed room where two people of the same
size standing in the two back corners will look very different in height
✔✔moon illusion - ✔✔the illusion where the moon looks larger when it is near the
horizon than it does when overhead
✔✔Ebbinghaus Illusion - ✔✔causes us to perceive a circle as larger when surrounded
by smaller circles and smaller when surrounded by larger circles
✔✔binocular rivalry - ✔✔The competition between the two eyes for control of visual
perception, which is evident when completely different stimuli are presented to the two
eyes
✔✔Binocular suppression - ✔✔A form of abnormal vision where one eye dominates the
other.
✔✔which school of psychology is associated with the following statement: "The
perception that emerges from a physical scene may not be directly predicted by the
sensory components that is is composed of, but emerges when we integrate the
components in a whole - ✔✔gestalt psychology
✔✔Quiroga et al. (2005) were able to examine single-cell recordings of human beings
prior to brain surgery. They found that: - ✔✔Specific cells in the medial temporal lobe
appeared to be specific to individual people
