Q

Myranda looks at a photograph of a truck. Which of the following best describes how she will perceive this photograph?

Q

The size-distance scaling equation explains the Ames Room illusion because

A

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

Q

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?

A

familiar size

Q

_______ is defined as depth perception created by input from both eyes.

A

Stereoscopic depth perception

17
Q

Ambrozia is a 4-month-old infant. Which depth cue is she most likely able to use?

A

binocular disparity

18
Q

Fox et al. (1980) found that the ability to use binocular disparity develops between

A

3.5 to 6 months

19
Q

A major assumption of the apparent-distance theory of the moon illusion is that the sky overhead

A

appears to be closer than the horizon because of the lack of depth cues

20
Q

The size-distance scaling equation explains Emmert’s Law because

A

retinal size is constant as perceived distance changes

21
Q

Individuals suffering from “walleye” and other conditions in which the eyes are misaligned have difficulty with depth perception because

A

the visual system suppresses vision in one eye in order to avoid having the experience of double vision

22
Q

Deletion and accretion are

A

effective for detecting depth at an edge

23
Q

When Uka and DeAngelis microstimulated disparity-selective neurons in a monkey, the monkey made a behavioral depth response based on the

A

tuning curve of the stimulated neurons

24
Q

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

A

occlusion

25
Q

The approximate visual angle of the width of your thumb held at arm’s length is ___ degrees.

A

2.0

26
Q

The ability to use binocular disparity as a depth cue

A

can be tested using random dot stereograms

27
Q

According to Day’s “conflicting cues theory”, the perception of vertical line lengths depends on

A

the actual length of the lines and the overall length of the figure

28
Q

An insect is most likely to use ______ to perceive depth.

A

movement parallax

29
Q

A person create binocular depth in video images by

A

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”

30
Q

According to Gregory’s misapplied size constancy scaling hypothesis, we perceive the “arrows pointing out” version of the Muller-Lyer illusion as

A

shorter, because it is perceived as being closer

31
Q

Gregory’s misapplied size constancy scaling explanation of the Muller-Lyer illusion

A

has difficulty in explaining the “dumbbell” version of the illusion

32
Q

Motion Parallax

A

is widely used to create depth in cartoons and video games

33
Q

A ________ is able to make use of binocular disparity, because it has _______ eyes.

A

cat; frontal
