Question 1

Which of the following statements about binocular visual neurons is NOT true?

Accepted Answer

Binocular visual neurons are involved in processing visual information from both eyes to perceive depth and distance. They do not inherently prefer crossed disparities (objects closer than the point of fixation) over uncrossed disparities (objects further than the point of fixation); rather, their response depends on the specific disparity they are tuned to, which can include both crossed and uncrossed disparities.

Question 2

Cats that are allowed to see with only one eye at atime from birth

Accepted Answer

Cats that are allowed to see with only one eye at a time from birth indeed have normal acuity in each eye, have their binocular neurons turned into monocular neurons, and are stereoblind. This is because the development of binocular vision and depth perception (stereopsis) requires input from both eyes during a critical period early in life. Without simultaneous input from both eyes, the neural circuitry necessary for processing binocular information does not develop properly, leading to these outcomes.

Question 3

When information available to the two eyes can't be fused into a single stable view, a portion of one eye's view is seen at a time. This phenomenon is called

Accepted Answer

Binocular rivalry occurs when each eye is presented with incompatible images, leading to an alternation in perception between the two images rather than their fusion into a single, coherent view.

Question 4

If you are stereoblind,

Accepted Answer

Stereoblindness can result from a condition called strabismus, where the eyes are misaligned, preventing proper binocular vision and depth perception.

Question 5

Chronic misalignment of one eye to the other is termed

Accepted Answer

Strabismus is the correct term for chronic misalignment of one eye relative to the other, where the eyes do not properly align with each other when looking at an object.

Question 6

To have the best chance of attaining normal vision, a child with strabismus should

Accepted Answer

Early surgical intervention, ideally before 1 year of age, is crucial for the best chance of developing normal binocular vision and preventing amblyopia in children with strabismus.

Question 7

Individuals unable to fixate on an object with both eyes simultaneously suffer from

Accepted Answer

Strabismus is a condition where the eyes do not properly align with each other when looking at an object, leading to an inability to fixate on the object with both eyes simultaneously.

Question 8

If Frank experiences convergence insufficiency it may cause which of the following?

Accepted Answer

Convergence insufficiency can lead to symptoms such as dizziness, headaches, and nausea because it affects the ability of the eyes to work together when looking at nearby objects, leading to strain and discomfort.

Question 9

When one object blocks the view of another, the object doing the blocking appears to be closer. This is the depth cue of

Accepted Answer

Occlusion is a depth cue where one object obscures part of another object, indicating that the obscuring object is closer to the viewer.

Question 10

The tendency to see as more distant an object whose contours are interrupted by those of other objects is referred to as

Accepted Answer

Occlusion refers to the visual perception principle where an object appears to be partially hidden behind another, leading to the perception that the occluded object is farther away. This is because the contours of the foreground object interrupt those of the background object, suggesting depth and spatial arrangement.

Question 11

Occlusion is NOT effective as a depth cue when

Accepted Answer

The answer of Occlusion is NOT effective as a depth...

Question 12

Which of the following is NOT a static monocular depth cue?

Accepted Answer

Diplopia, or double vision, is not a static monocular depth cue; it involves binocular vision where both eyes are used.

Question 13

The tendency to perceive all of an object whose contours are interrupted by those of other objects is referred to as

Accepted Answer

Amodal completion is the visual system's tendency to perceive the whole of a shape or object even when its parts are partially obscured by other objects, effectively "filling in" the missing information.

Question 14

Which of the following involve(s) depth perception among partially overlapping objects?

Accepted Answer

Neon spreading and transparency both involve depth perception among partially overlapping objects. Neon spreading is the illusion of a bright line spreading out from the edge of an object, and transparency is the illusion of seeing through an object. Both of these illusions can be caused by the brain's attempt to interpret the depth of the scene.

Question 15

Suzanne was a typical participant in a test requiring her to state whether an object appeared the same as or different from a brief priming stimulus. Compared to when the objects were different, when the objects were identical her reaction time was

Accepted Answer

When objects are identical, reaction times in such tasks are typically faster because it's easier for the brain to process and recognize the similarity between the priming stimulus and the target object, leading to quicker responses.

Question 16

A priming stimulus depicts a square in front of a disk so that the retinal image of the disk has one quadrant removed. When the test stimulus is a pair of disks, reaction times to decide that the disks are the same are

Accepted Answer

The answer of A priming stimulus depicts a square in...

Question 17

Which of the following statements is true?

Accepted Answer

Both apparent size and perceived distance can influence each other. For example, objects that appear larger are often perceived as being closer, while the distance at which an object is perceived can also influence its perceived size. This is a fundamental concept in the study of perception, illustrating the interplay between size and distance in visual processing.

Question 18

The moon illusion is that the moon appears

Accepted Answer

The moon illusion refers to the phenomenon where the moon appears larger when it is close to the horizon than when it is higher up in the sky, or at its zenith. This is a perceptual illusion; the moon is not physically larger or closer, but it appears so due to the way our brains interpret visual cues in the context of the horizon and objects on the Earth's surface.

Question 19

According to the perceived-distance explanation of the moon illusion the moon appears to be farthest away when it is

Accepted Answer

According to the perceived-distance explanation of the moon illusion, the moon appears to be farthest away when it is at the horizon. This is because objects on the horizon are typically seen across the vast distances of the Earth's surface, which makes them appear farther away compared to when they are overhead.

Question 20

The interdependence of perceived size and perceived distance is demonstrated by

Accepted Answer

Both the Ames room and the moon illusion demonstrate the interdependence of perceived size and perceived distance. The Ames room illusion occurs because of a distorted room that makes two objects of the same size appear different in size due to their perceived distance. The moon illusion involves the moon appearing larger near the horizon than it does higher in the sky, again due to cues about perceived distance affecting perceived size.
