Chapter 10 Flashcards
_______ is a term used to describe conditions in which movements between the two eyes are not coordinated.
Strabismus
Merrill watches his finger with both eyes as he brings it closer to his nose. As the finger gets closer, his eyes move inward and he feels his eye muscles working. Which depth cue is associated with the feeling he is getting from his eye muscles?
both accommodation and convergence
The key to the Ames Room illusion is
the room is constructed of trapezoids, but looks rectangular to the observer
The depth cue of ________ is the most important in the Ponzo (railroad track) illusion.
perspective convergence
As Tyler looks down a railroad track, he perceives the sides of the tracks as becoming closer as the distance increases. This is an example of
perspective convergence
The size-distance scaling equation is S = K(R x D). The “S” in the equation stands for
an object’s perceived size
The correspondence problem is best demonstrated by
random-dot stereograms
The depth cue that is responsible for perceiving depth in ViewMasters™ and “3-D” movies is
binocular disparity
Blake and Hirsch (1975) use selective rearing of kittens to show that
disparity-selective neurons are responsible for stereopsis
Myranda looks at a photograph of a truck. Which of the following best describes how she will perceive this photograph?
Her perception of the size of the truck will depend on the known size of the objects located next to the truck
The size-distance scaling equation explains the Ames Room illusion because
we perceive the two people in the room to be different sizes because they are perceived to be at the same distance away and their retinal image size is different
Several years ago, Bryce, a fan of the Houston Rockets basketball team, saw the player Yao Ming (who is 7’6” tall) standing next to his coach Jeff VanGundy (who is less than 6 feet tall). Bryce correctly perceived the two men as being the same distance away from her. Which depth cue most influenced her perception?
familiar size
Which of the following depth cues is effective both from 0-2 meters and above 30 meters?
occlusion
The importance of _______________ is that these stimuli rely solely on binocular disparity to provide the impression of depth.
random dot stereograms
________ is the difference in the images in the two eyes; _____ is the impression of depth that results from this information.
Binocular disparity; stereopsis
_______ is defined as depth perception created by input from both eyes.
Stereoscopic depth perception
Ambrozia is a 4-month-old infant. Which depth cue is she most likely able to use?
binocular disparity
Fox et al. (1980) found that the ability to use binocular disparity develops between
3.5 to 6 months
A major assumption of the apparent-distance theory of the moon illusion is that the sky overhead
appears to be closer than the horizon because of the lack of depth cues
The size-distance scaling equation explains Emmert’s Law because
retinal size is constant as perceived distance changes
Individuals suffering from “walleye” and other conditions in which the eyes are misaligned have difficulty with depth perception because
the visual system suppresses vision in one eye in order to avoid having the experience of double vision
Deletion and accretion are
effective for detecting depth at an edge
When Uka and DeAngelis microstimulated disparity-selective neurons in a monkey, the monkey made a behavioral depth response based on the
tuning curve of the stimulated neurons
When your professor stands in back of a podium, you perceive your professor as being further away than the podium because the podium blocks the vision of the professor’s body. This is an example of the depth cue
occlusion
The approximate visual angle of the width of your thumb held at arm’s length is ___ degrees.
2.0
The ability to use binocular disparity as a depth cue
can be tested using random dot stereograms
According to Day’s “conflicting cues theory”, the perception of vertical line lengths depends on
the actual length of the lines and the overall length of the figure
An insect is most likely to use ______ to perceive depth.
movement parallax
A person create binocular depth in video images by
filming from two slightly displaced positions using polarized light.
filming from two slightly displaced positions using red and green filters.
filming from two slightly displaced positions and alternating between “eyes”
According to Gregory’s misapplied size constancy scaling hypothesis, we perceive the “arrows pointing out” version of the Muller-Lyer illusion as
shorter, because it is perceived as being closer
Gregory’s misapplied size constancy scaling explanation of the Muller-Lyer illusion
has difficulty in explaining the “dumbbell” version of the illusion
Motion Parallax
is widely used to create depth in cartoons and video games
A ________ is able to make use of binocular disparity, because it has _______ eyes.
cat; frontal
