Question 1

Misty is standing at the edge of a large field of flowers.She perceives the flowers lower in her visual field as _____ than are the flowers higher in her visual field due to _____.

Accepted Answer

Misty perceives the flowers lower in her visual field as closer than the flowers higher in her visual field due to the relative height in the image. This is a monocular cue that helps perceive depth from a single eye. As the lower flowers obstruct the view of the higher flowers, they appear closer to the observer.

Question 2

From three-dimensional geometric elements such as cubes and tetrahedrons,along with their spatial relations,Jesse recognizes that he is standing in front of a house.This BEST illustrates _____ theories of object recognition.

Accepted Answer

The parts-based theory of object recognition suggests that we recognize objects by breaking them down into their component parts or geometric elements. In this scenario, Jesse is recognizing the house based on its three-dimensional geometric elements such as cubes and tetrahedrons, which supports the parts-based theory.

Question 3

Objects that cast a GREATER retinal disparity are perceived as being:

Accepted Answer

Objects that cast a greater retinal disparity are perceived as being closer. Retinal disparity refers to the slight difference in the image seen by each eye due to their slightly different perspectives. The brain uses this disparity to determine depth and distance, with greater disparity meaning the object is closer.

Question 4

Because the brown bear is partially obscured by the car,Nick assumes that the car is closer to him than is the bear.Nick is depending on the cue called:

Accepted Answer

Interposition refers to objects that appear to be closer because they are in front of other objects. In this case, the car is partially obscuring the bear, leading Nick to assume that the car is closer. This cue is also known as overlap. Relative size refers to objects appearing smaller when they are farther away, texture gradient refers to the change in texture or detail as objects move farther away, and retinal disparity refers to the slight difference in the image each eye sees. None of these cues seem to be relevant in this scenario.

Question 5

Which statement about object recognition theories is FALSE?

Accepted Answer

Image-based theories can account for how we recognize a friend's face from a stranger's face by relying on holistic processing of facial features and their relationships.

Question 6

A factor that does NOT help us to determine figure from ground is:

Accepted Answer

Opponent colors (colors of other objects in the scene) do not help in determining figure from ground. The other options - edges, size, and motion - all contribute to the perception of figure-ground relationships.

Question 7

Objects that cast a SMALLER retinal disparity are perceived as being:

Accepted Answer

Objects that cast a smaller retinal disparity are perceived as being farther away because retinal disparity decreases as objects move further from the observer, contributing to depth perception.

Question 8

Painting a field of sunflowers,Casey delineated the flowers in the foreground and blended those farther away in the field,as she saw them in life.She was depicting:

Accepted Answer

Casey's technique of blending the sunflowers that are farther away to depict depth is an example of a texture gradient. This is a monocular cue in perception that shows that as a texture or pattern becomes denser or less distinct, it appears farther away.

Question 9

Geon is to object as:

Accepted Answer

Geon refers to a basic geometric element or shape. Gears are basic components of a machine. The relationship between "geon" and "object" is similar to the relationship between "gears" and "machine."

Question 10

Object is to geon as:

Accepted Answer

The answer of Object is to geon as:
...

Question 11

Closer objects cast larger images on the retina than do objects that are farther away,a _____ depth cue known as _____.

Accepted Answer

The given depth cue of "closer objects cast larger images on the retina than do objects that are farther away" is a monocular cue. The specific cue being described is relative size, as the comparison of the size of the image of an object on the retina to the known size of the object helps the brain determine the object's distance.

Question 12

A graphic artist's rather large computer monitor sitting on her desk partially obscures the window of her office.When sitting at her desk,she perceives the monitor to be in front of the window as a result of the depth cue termed:

Accepted Answer

Interposition is the depth cue that occurs when one object partially blocks or obscures another object. In this scenario, the computer monitor is partially blocking the window, making it appear as though it is in front of the window.

Question 13

Railway tracks seem to converge in the distance,an example of the monocular depth cue known as:

Accepted Answer

Linear perspective refers to the fact that parallel lines appear to converge in the distance, creating a sense of depth and distance. This is precisely what is happening with the railway tracks in the example given. The other options, texture gradient, interposition, and retinal disparity, do not apply to this specific example.

Question 14

According to _____ theories,the brain recognizes objects by comparing the current pattern of retinal stimulation to its library of mental templates of objects.

Accepted Answer

Image-based theories propose that the brain recognizes objects by comparing the entire image to a stored representation of the object, without breaking it down into smaller component parts or features. This contrasts with geon-based and parts-based theories, which focus on recognizing objects based on their individual parts or geometrical shapes, and feature-detection-based theories, which involve recognizing objects based on specific features such as edges or lines.

Question 15

A stage actor can see the facial expressions of the audience members sitting in the front row,but the faces of people sitting farther away are blurry.This example illustrates the depth cue of:

Accepted Answer

The answer of A stage actor can see the facial...

Question 16

A(n)_____ is a mental representation that can be directly compared with a viewed shape in the retinal image.

Accepted Answer

A template is a mental representation or model that can be directly compared with a viewed shape in the retinal image. Templates are stored in memory and can be used to identify familiar objects quickly and efficiently. However, templates are limited in their ability to account for variations in size, rotation, and other features that may be present in real-world objects.

Question 17

When two objects cast a retinal image of the same size,the one that is perceived as being _____ will be perceived as _____.

Accepted Answer

When two objects cast a retinal image of the same size, the one that is perceived as being farther away will be perceived as larger due to the brain's interpretation of distance and size scaling. This is because, for an object to project the same size image on the retina from a farther distance, it must be larger than an object closer by.

Question 18

Kevin correctly judged that his car was parked farther from his classroom than was his friend's car because it cast a smaller image on his retina than did his friend's.His brain was making use of a monocular cue called:

Accepted Answer

Familiar size is a monocular cue that our brain uses to judge distance based on our knowledge of the object's typical size. In this case, Kevin's brain used the known size of cars to determine that his car, which appeared smaller, was farther away than his friend's car.

Question 19

To the pilot,the long straight runway appears to converge to a single point in the distance.This is an example of the monocular depth cue known as:

Accepted Answer

Linear perspective is the monocular depth cue that occurs when parallel lines appear to converge at a single point in the distance, as is the case with the long straight runway. Texture gradient, interposition, and retinal disparity are other monocular depth cues, but do not apply to this scenario.

Question 20

The Rubin vase illusion illustrates:

Accepted Answer

The Rubin vase illusion is a classic example of a reversible figure-ground relationship, where the viewer can perceive either a white vase on a black background or two black faces on a white background, depending on their focus. This illusion highlights how our perceptual organization can flip between different interpretations of an image.

Quiz 4: Sensation and Perception
