Question 1

When viewing nearby objects, the angle between the eyes is __________ when viewing distant objects.
A) larger than
B) much smaller than
C) about the same size as
D) slightly smaller than
E) twice as large as

Accepted Answer

When viewing nearby objects, the angle between the eyes (convergence angle) is larger than when viewing distant objects. This is because the eyes must turn inward (converge) more to focus on closer objects, resulting in a larger angle.

Question 2

The basis for interposition working well as a depth cue with unfamiliar stimuli involves the
A) Gestalt law of common fate.
B) Gestalt law of proximity.
C) principle of good form.
D) Gestalt law of good continuation.
E) Gestalt law of similarity.

Accepted Answer

Interposition works as a depth cue because it relies on the principle of good form, where objects that are partially obscured by others are perceived as being further away, creating a sense of depth.

Question 3

On my desk is a piece of pottery that I use to hold pens. It partially blocks my view of my telephone. I can tell from this that the telephone is farther away from me than the pottery. The cue to depth that I am describing here is called
A) texture.
B) linear perspective.
C) shading.
D) interposition.
E) retinal disparity.

Accepted Answer

Interposition, also known as occlusion, is a visual cue that occurs when one object partially covers or obscures the view of a second object, indicating that the first object is closer to the viewer. In this scenario, the piece of pottery obscures part of the telephone, suggesting that the pottery is closer to the observer than the telephone.

Question 4

As parallel lines recede, they appear to converge on a vanishing point somewhere in the distance, giving us the impression of depth. This cue is called
A) convergence.
B) retinal disparity.
C) interposition.
D) linear perspective.
E) the principle of good form.

Accepted Answer

Linear perspective is the depth cue that describes how parallel lines appear to converge as they recede into the distance, meeting at a vanishing point on the horizon. This phenomenon helps create the illusion of depth in a two-dimensional image.

Question 5

As I look down the road, the white lines that mark its exterior boundaries seem to converge in the distance. As the lines appear to become closer to each other, they look farther away. The cue to depth that I am describing is called
A) haze.
B) texture.
C) linear perspective.
D) convergence.
E) retinal disparity.

Accepted Answer

The cue to depth described is linear perspective, which refers to the way parallel lines appear to converge as they recede into the distance, giving a cue for depth perception.

Question 6

Question 7

As I look out of my office window, I can make out the details of nearby objects very easily. As I look at objects farther away, I have a more difficult time in making out the details of different objects. This example describes the cue to depth called
A) linear perspective.
B) retinal disparity.
C) shading.
D) interposition.
E) texture.

Accepted Answer

Texture gradient is a depth cue where objects closer to the viewer appear more detailed, while those further away appear less detailed.

Question 8

The fact that an object will appear closer the more coarse its surface, is due to the monocular cue of
A) linear perspective.
B) texture.
C) shading.
D) interposition.
E) retinal disparity.

Accepted Answer

Texture gradient is a monocular cue that allows us to perceive depth. It refers to the way we can see details more clearly on closer objects, while distant objects appear smoother or less textured. This cue helps in judging distances based on the known size of objects or patterns.

Question 9

From a distance, a rocky beach doesn't appear all that rocky. Instead, it appears smooth and all of the rocks appear to blend in with each other. However, as we get closer and closer to the beach, we can see that the beach is made up of many individual rocks, each with distinct shapes and sizes. The cue to depth that is described in this example is called
A) convergence.
B) context.
C) haze.
D) texture.
E) interposition.

Accepted Answer

The cue to depth described is texture gradient, which refers to the way texture becomes denser and finer as it recedes into the distance, making distant objects appear smoother and less detailed. This is why the rocky beach appears smooth from a distance but reveals individual rocks upon closer inspection.

Question 10

As I look out my window, distant objects appear less distinct than nearby objects. This example describes the monocular cue of
A) linear perspective.
B) haze.
C) shading.
D) interposition.
E) retinal disparity.

Accepted Answer

Haze is a monocular cue that helps in depth perception by making distant objects appear less distinct than nearby objects due to particles in the air scattering light.

Question 11

Among cues to depth perception, both __________ and __________ rely on the clarity of the image to determine distance.
A) shading; interposition
B) retinal disparity; convergence
C) interposition; haze
D) linear perspective; shading
E) texture; haze

Accepted Answer

Texture and haze both rely on the clarity of the image to determine distance, as objects that are farther away tend to appear less clear and more hazy.

Question 12

The top of a convex or bulging item appears light coloured while the bottom appears darker. Thus, our visual system appears to interpret such stimuli as if they were illuminated from directly above. The cue to depth that seems to be at work in this context is
A) shading.
B) haze.
C) texture.
D) elevation.
E) convergence.

Accepted Answer

Shading is a cue to depth perception that involves changes in light and shadow to suggest form and contours. When an object is convex, the way it is shaded, with the top appearing lighter and the bottom darker, suggests to our visual system that it is being illuminated from above, helping to perceive its shape and depth.

Question 13

Which cue to depth perception does not tell us much about absolute distances of objects but does tell us which parts of the object are closer or further away?
A) texture
B) haze
C) shading
D) interposition
E) elevation

Accepted Answer

Shading provides information about the relative depth of different parts of an object by indicating which areas are closer to the light source and which are further away, but it does not provide absolute distance information.

Question 14

Objects nearest the horizon line appear __________ than other objects.
A) farther away
B) slightly closer
C) much closer
D) larger
E) no different

Accepted Answer

Objects nearest the horizon line appear farther away due to perspective. As objects get closer to the horizon line in a drawing or view, they seem to be further away from the viewer, which is a basic principle of perspective drawing.

Question 15

Objects nearest the horizon line are seen as farther away in the monocular cue of
A) shading.
B) haze.
C) texture.
D) elevation.
E) convergence.

Accepted Answer

Elevation is a monocular cue where objects closer to the horizon are perceived as being farther away than objects further from the horizon, helping to create a sense of depth in a scene.

Question 16

As we move past a visual scene, stationary objects closer to us appear to pass in front of objects farther away. This depth cue is called
A) convergence.
B) linear perspective.
C) motion parallax.
D) elevation.
E) interposition.

Accepted Answer

Motion parallax is the depth cue where objects closer to the observer appear to move faster than objects farther away when the observer moves past them. This difference in speed helps the brain perceive depth.

Question 17

Which monocular cue to depth perception depends on our own movement?
A) linear perspective
B) elevation
C) interposition
D) convergence
E) motion parallax

Accepted Answer

Motion parallax is the monocular cue to depth perception that depends on our own movement. As we move, objects that are closer to us move faster across our field of vision than those that are further away, giving us a sense of depth.

Question 18

The paper in the book that I am reading appears to be white regardless of whether I am reading the book outside or inside and regardless of whether I am sitting in the shade, in the sun, or under a lamp. My perception of the colour of the paper is an example of
A) haze.
B) brightness constancy.
C) the illumination illusion.
D) perceptual reactance.
E) shading.

Accepted Answer

Brightness constancy is a feature of human vision where the perceived brightness of objects remains constant under varying illumination conditions. This explains why the paper appears white whether you're reading in sunlight, shade, or artificial light.

Question 19

Ami is looking at a gray house. One wall is in the sun; another wall is in the shade. To Ami, though, the two walls appear to be the same shade of gray. Ami's experience is an example of
A) perceptual constancy.
B) perceptual illusion.
C) perceptual reactance.
D) optical distortion.
E) haze.

Accepted Answer

Perceptual constancy refers to our ability to see objects as appearing the same even under different lighting conditions, distances, and angles. In this scenario, Ami perceives both walls as being the same shade of gray despite one being in the sun and the other in the shade, illustrating perceptual constancy.

Question 20

Which of the following is NOT one of the types of perceptual constancy?
A) form
B) size
C) number
D) brightness
E) colour

Accepted Answer

Number constancy is not recognized as a type of perceptual constancy. Perceptual constancy refers to the ability of the perceptual system to recognize objects as having constant properties (such as form, size, brightness, and color) even though sensory input may vary.
