Question 1

The specialization evident in visual processing shows that

Accepted Answer

The specialization evident in visual processing shows that the visual system relies on parallel processing, meaning that different aspects of visual processing occur simultaneously and in parallel rather than in a strict serial manner. This is evidenced by the fact that different regions of the brain are responsible for processing different visual features, such as color, motion, and form.

Question 2

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

Accepted Answer

The sentence "Go beyond the information given" best illustrates the effect that Gestalt principles have on perception. Gestalt principles help us organize and interpret sensory information into meaningful patterns, even when the information is incomplete or ambiguous. When we go beyond the information given, we use our knowledge and experience to fill in the gaps and make sense of what we are perceiving. This is a key aspect of Gestalt psychology and its impact on perception.

Question 3

________ 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 are specialized for spatial analysis and form detection, while magnocellular cells are specialized for the detection of motion and depth. Therefore, choice D, which correctly identifies parvocellular and magnocellular cells, is the best answer.

Question 4

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

Accepted Answer

The Gestalt psychologists believed that perception was not just the sum of individual sensory elements, but that the whole was greater than the sum of its parts. This means that the way we perceive things is influenced not just by the individual components, but also by the context and organization of those components.

Question 5

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, also known as motion blindness, is a condition in which an individual is unable to perceive motion. This would explain Brad's inability to see the arms of a clock move. Change blindness refers to the phenomenon in which an individual is unable to perceive changes in a visual scene. Visual neglect is a condition in which an individual ignores or neglects one side of their visual field. Prosopagnosia is a condition in which an individual is unable to recognize faces. None of these conditions would explain Brad's specific inability to perceive motion.

Question 6

Which of the following characteristics is NOT used to diagnose visual stimuli by neurons in the visual system?

Accepted Answer

The answer of Which of the following characteristics is NOT...

Question 7

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 8

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

Accepted Answer

The answer of Which of the following does NOT provide...

Question 9

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

Accepted Answer

The face/vase example shows that when an image is ambiguous, the mind can interpret it in multiple ways, leading to different perceptions of the same image. This demonstrates the principle of perceptual organization known as "multistability."

Question 10

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 parts of the brain work together to create a unified perception or experience is known as the binding problem.

Question 11

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 12

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

Accepted Answer

Akinetopsia or motion blindness is a rare neurological disorder that affects a person's ability to perceive motion. The inability to recognize faces is not specifically related to this disorder, and is more commonly associated with prosopagnosia (face blindness). Therefore, someone with akinetopsia would have difficulty with choices A, B, and C, but not with recognizing faces (choice D).

Question 13

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 14

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

Accepted Answer

Visual agnosia is a type of visual processing disorder in which the affected person is unable to recognize or identify objects, despite having intact vision. This condition is typically associated with damage to the "what" system, which carries visual information from the occipital cortex to the temporal cortex, where object identification occurs. Damage to this system may also result in other related symptoms, such as prosopagnosia (inability to recognize faces) and achromatopsia (inability to perceive colors). Therefore, choice C is the best answer.

Question 15

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

Accepted Answer

Processing information only once is actually an advantage of parallel processing, thus it would not be considered a disadvantage.

Question 16

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

Accepted Answer

Memory is not directly involved in perceiving the visual world or reuniting various elements of a scene together. Instead, memory may play a role in recognizing specific objects or scenes based on past experiences. Attention, spatial position, and different groups of neurons firing in synchrony are all important factors in integrating elements of a scene for visual perception.

Question 17

Some people have sustained brain damage and lost the ability to identify color. Other people 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 different aspects of visual processing indicates that there is specialization in our visual system. This specialization allows for the efficient processing of complex visual information.

Question 18

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

Accepted Answer

The statement "The lines on the page contradict one another and so a cube can never be perceived" is false. While the lines are ambiguous and do not definitively suggest one orientation over the other, they do not contradict each other to the extent that perception of a cube is impossible.

Question 19

Parvo cells are similar to magno cells in what way?

Accepted Answer

Parvo cells and magno cells are both located in the visual system. Parvo cells are found mainly in the foveal and parafoveal regions while magno cells are found in the peripheral regions. However, they differ in terms of cell size, receptive field size, and firing pattern.

Question 20

You are at the zoo watching a tiger sleep. It suddenly awakes and lurches in your direction. Spatial position would NOT provide information about the tiger's

Accepted Answer

Spatial position would not provide information about the tiger's dangerous nature. It may be dangerous even if it is far away or in a different location. The color, form, and motion patterns of the tiger may give information about its species, health, and behavior.
