Question 1

Which of the following statements most accurately represents the order of events involved in interpreting a visual stimulus?

Accepted Answer

The answer of Which of the following statements most accurately...

Question 2

To perceive the visual world,we have to bind various elements of a scene together so that they are perceived in an integrated fashion.Which of the following is NOT likely to be involved in this process?

Accepted Answer

Iconic memory is a form of sensory memory that preserves an image of a visual stimulus for a brief period after it has disappeared from view. While it is important for visual perception, it is not directly involved in the process of binding various elements of a scene together. Attention, spatial position, and synchronous firing of neurons are all important for visual binding.

Question 3

Brad is able to read a clock but is unable to see the arms of a clock move from position to position.He is suffering from

Accepted Answer

Akinetopsia is a condition where a person is unable to perceive motion, but can see individual still images. In this case, Brad can read a clock, but is unable to see the arms of the clock move, indicating a problem with motion perception rather than a problem with visual attention or recognition. Change blindness is a phenomenon where people fail to notice changes in visual stimuli due to limitations in attention and memory. Visual neglect is a lack of awareness of one side of the visual field, and prosopagnosia is difficulty recognizing faces. None of these conditions accurately describe Brad's situation.

Question 4

The specialization evident in visual processing shows that

Accepted Answer

The specialization evident in visual processing, such as the processing of color, movement, and spatial orientation, shows that the visual system relies on parallel processing. This means that different aspects of visual processing occur simultaneously and are processed by different areas of the brain, not exclusively within the occipital cortex. Additionally, although the right hemisphere is generally more involved in spatial processing, visual processing occurs in both hemispheres. Therefore, option A is the best choice.

Question 5

________ cells in the LGN are specialized for spatial analysis and form detection,whereas ________ cells are specialized for the detection of motion and depth.

Accepted Answer

Parvocellular cells in the LGN are specialized for spatial analysis and form detection, while magnocellular cells are specialized for the detection of motion and depth. Therefore, option D is the correct answer. Option A is incorrect because parvocellular and p-cells are the same thing. Option B is incorrect because M-cells and magnocellular cells are the same thing.

Question 6

Which of the following characteristics seems NOT to carry information within the visual system?

Accepted Answer

The shape of the neuron does not carry information within the visual system. While the shape of a neuron may affect its function, such as its ability to connect with other neurons, it does not directly encode information about the visual environment. In contrast, the rate and rhythm of firing of a neuron, as well as the chemicals it releases, can all carry important information within the visual system.

Question 7

Visual agnosia is associated with damage to which of the following?

Accepted Answer

Visual agnosia is a disorder that affects recognition of objects or shapes. It is typically associated with damage to the "what" system, which carries information from the occipital cortex to the temporal cortex. This system is responsible for object recognition and is especially important in identifying complex visual stimuli such as faces, letters, and symbols. Damage to other visual areas such as V1 or MT can result in different visual deficits but usually not agnosia.

Question 8

The primary visual cortex is located

Accepted Answer

The primary visual cortex is located in the occipital lobe at the back of the brain, which is the part of the cortex that is farthest from the eyes. This area is responsible for processing visual information.

Question 9

The Necker cube is an ambiguous figure.Which of the following statements regarding the cube is FALSE?

Accepted Answer

The lines on the page of a Necker cube do not contradict one another; instead, they allow for multiple interpretations of the cube's orientation without any inherent contradiction. The perception of the cube can switch between different orientations, but this is not due to contradictory information in the lines themselves.

Question 10

Some people have sustained brain damage and lost the ability to identify color.Other people have sustained damage to a different area of the brain and lost the ability to detect motion.What does this indicate about our visual system?

Accepted Answer

The fact that different areas of the brain are responsible for identifying color and detecting motion suggests that our visual system has specialized areas for processing different kinds of visual information. This is consistent with the idea of functional specialization in the brain, where different areas are dedicated to processing different aspects of sensory information.

Question 11

Which of the following sentences best illustrates the effect that Gestalt principles have on perception?

Accepted Answer

Gestalt principles are concerned with how humans perceive things as a whole, rather than as individual parts. This principle encourages individuals to "go beyond the information given" and to perceive objects as a unified whole.

Question 12

Which of the following would NOT be considered an advantage of parallel processing in the visual system?

Accepted Answer

Parallel processing involves processing information simultaneously in different areas of the brain, which leads to faster and more efficient processing. Disparate systems can work together to negotiate an accurate interpretation, which is also an advantage. However, information is processed multiple times, not just once, in parallel processing, which is the opposite of choice B. Therefore, B would not be considered an advantage of parallel processing in the visual system.

Question 13

In order to summarize the Gestalt psychologists' movement in a few words,one might say,

Accepted Answer

The statement "The perceptual whole is different than the sum of its parts" encapsulates the main idea behind the Gestalt psychology movement. They believed that perception is not just the combination of individual sensory elements, but instead, the brain seeks to organize these elements into a meaningful and coherent whole.

Question 14

Julie has sustained damage to the "what" system in her brain.She will likely have difficulty with which of the following tasks?

Accepted Answer

The "what" system, also known as the ventral stream, is involved in object recognition and identification. Damage to this system would impair the ability to identify objects, such as a chair.

Question 15

The face/vase example illustrates what important principle of perceptual organization?

Accepted Answer

The face/vase example demonstrates that an ambiguous image can be interpreted in different ways at different times, depending on the context and the perceiver's expectations and prior experiences. This principle is known as perceptual organization or figure-ground perception.

Question 16

Human brains have a distinct division-of-labor strategy.Each task is achieved as a result of multiple brain areas working together.But the work of the various parts of the brain must be compiled into a finished whole.The issue of how this reassembly works is referred to as the

Accepted Answer

The issue of how different areas of the brain work together to create a coherent perception or experience is known as the "binding problem." It refers to the challenge of understanding how various pieces of sensory information are integrated and processed to create a unified perception. Therefore, option A is the correct answer. The other options (B, C, D) do not refer to this concept.

Question 17

Which of the following is NOT one of the Gestalt principles governing perception?

Accepted Answer

Complexity is not one of the Gestalt principles governing perception. The correct principles are good continuation, proximity, and closure, among others.

Question 18

Jenna sees a picture of a dog standing in front of a tree.The dog is blocking part of Jenna's view,so that she cannot see a portion of the tree trunk.Jenna does,however,perceive the tree to have an intact,continuous trunk.Jenna's perception reminds us that

Accepted Answer

Jenna's perception demonstrates the Gestalt principle of closure, where people tend to fill in missing information to perceive whole and complete objects. This principle suggests that people actively contribute to their perception by organizing sensory inputs into meaningful patterns. Thus, the answer is A, and the other options are not relevant or accurate regarding Jenna's perception.

Question 19

Which of the following does NOT provide an example for parallel processing in the visual system?

Accepted Answer

This statement describes the sequential processing of visual information from the retina to the LGN to the visual cortex, rather than parallel processing.

Question 20

Someone with akinetopsia would have difficulty with all of the following EXCEPT

Accepted Answer

Akinetopsia is a condition where a person has difficulty perceiving motion. Recognizing faces does not require the perception of motion, unlike the other activities listed.
