Question 1

Which of the following statements MOST accurately describes how visual information is transmitted to the brain? ​
A)Signals from each eye only go to the corresponding (same)hemisphere of the brain.
B)Signals from both eyes go to both hemispheres of the brain.
C)Signals from each eye only go to the opposite hemisphere of the brain.
D)Signals from the fovea of each eye go to the left hemisphere, and signals from the remaining areas of the retina go to the right hemisphere.

Accepted Answer

Visual information from both eyes is split at the optic chiasm, allowing signals from the left visual field of both eyes to be processed in the right hemisphere and signals from the right visual field of both eyes to be processed in the left hemisphere. This ensures that signals from both eyes go to both hemispheres of the brain.

Question 2

Pairs of colors that produce gray tones when mixed together are known as _____ colors.
A)sedentary
B)grayscale
C)complex
D)complementary

Accepted Answer

Complementary colors, when mixed together, produce gray tones because they are opposite each other on the color wheel and effectively neutralize each other's hue.

Question 3

The action of the visual receptors supports the _____ theory of color vision.
A)Hering
B)opponent-process
C)James-Lange
D)trichromatic

Accepted Answer

The trichromatic theory of color vision is supported by the action of visual receptors, as it explains how the three types of cones in the retina are responsible for detecting different wavelengths of light corresponding to red, green, and blue.

Question 4

While finger painting, Chris mixed yellow paint and blue paint and ended up with green, an example of ​
A)trichromatic theory.
B)additive color mixing.
C)subtractive color mixing.
D)multiplicative color mixing.

Accepted Answer

Subtractive color mixing occurs when pigments are combined, such as mixing yellow and blue paints to create green.

Question 5

If you mix red, green, and blue paint, you will get ​
A)purple.
B)white.
C)orange.
D)black.

Accepted Answer

Mixing red, green, and blue paint, which are primary colors in the subtractive color model, typically results in a dark color like black due to the absorption of most wavelengths of light.

Question 6

Eric has been wearing red welding goggles for the past 30 minutes. Based on the opponent-process theory of color vision, when Eric takes off the red goggles, he should expect that objects will temporarily appear to be ​
A)blue.
B)yellow.
C)orange.
D)green.

Accepted Answer

The opponent-process theory of color vision suggests that colors are perceived through the operation of opposing pairs of colors: red-green, blue-yellow, and black-white. After wearing red goggles, Eric's vision would adapt to reduce the impact of the overwhelming red input. When the goggles are removed, the balance shifts towards the opposing color, green, making objects appear temporarily greenish.

Question 7

After visual information is processed in the primary visual cortex, it is often routed to other cortical areas for additional processing through two pathways characterized as the _____ pathways.
A)form and color
B)what and when
C)what and where
D)motion and depth

Accepted Answer

The two pathways are known as the "what" and "where" pathways, which are involved in processing object identity and object location, respectively.

Question 8

The _____theory of color vision holds that we perceive colors because of pairs of receptors that make antagonistic responses.
A)opponent process
B)trichromatic
C)color mixing
D)color diluting

Accepted Answer

The opponent process theory of color vision suggests that our ability to perceive color is controlled by three receptor complexes with opposing actions, which explains why we see colors as opposites (e.g., red-green, blue-yellow).

Question 9

Recent research suggests that _____ can discriminate colors more effectively than _____.
A)men; women
B)women; men
C)children; adults
D)adults; children

Accepted Answer

Recent research has shown that women tend to have a more nuanced perception of colors compared to men, likely due to genetic differences related to the X chromosome, where the genes for the most common forms of color vision are located.

Question 10

While visiting the art museum, Laura stared at a black and white photograph in a yellow frame for over a minute. When she looked away from the photograph, she saw an afterimage of a rectangle. Consistent with the opponent process theory, the image she saw was
A)green.
B)red.
C)blue.
D)yellow.

Accepted Answer

The answer of While visiting the art museum, Laura stared...

Question 11

Researchers investigating feature detectors have found individual neurons that are activated by images of faces. These neurons may be adaptive primarily because they allow us to distinguish
A)friends from foes.
B)people from animals.
C)animals from plants.
D)animals from food.

Accepted Answer

The ability to distinguish friends from foes is crucial for social interaction and survival, making the specialized function of face-detecting neurons highly adaptive in social contexts. Recognizing and interpreting faces allows individuals to identify potential threats or allies, facilitating appropriate social responses.

Question 12

At the musical he attended over the weekend, Andrew noticed that whenever the red and green spotlights overlapped, they seemed to change to a yellow spotlight. This can be explained using the principles of
A)additive color mixing.
B)subtractive color mixing.
C)hypercomplex feature detection.
D)opponent processing of colors.

Accepted Answer

Additive color mixing occurs when different colors of light are combined, with the resulting light being a mixture of the wavelengths of the original lights. When red and green lights overlap, they create yellow light, which is a direct example of additive color mixing.

Question 13

The point where axons cross over from the inside half of each eye to the opposite half of the brain is the ​
A)optic disk.
B)optic chiasm.
C)visual solenoid.
D)optic nerve.

Accepted Answer

The optic chiasm is the part of the brain where the nerve fibers from the inside half of each eye cross over to the opposite side of the brain. This crossing allows visual information from both eyes to be processed by both hemispheres of the brain, which is crucial for depth perception and a wide field of view.

Question 14

Television sets are able to recreate the entire visible spectrum by additively mixing three primary colors. This process is similar to the view of human color vision called _____ theory.
A)opponent-process
B)saturation
C)complementary color
D)trichromatic

Accepted Answer

The trichromatic theory of color vision posits that the human eye has three types of receptors sensitive to three primary colors: red, green, and blue. This theory explains how television sets can recreate the visible spectrum by mixing these three colors.

Question 15

After having your picture taken with a yellow flash, you momentarily see blue spots floating before your eyes. This phenomenon is BEST explained by
A)subtractive color mixing.
B)opponent process theory.
C)additive color mixing.
D)trichromatic theory.

Accepted Answer

The opponent process theory explains this phenomenon, as it suggests that colors come in pairs, and exposure to one can lead to afterimages of the other. In this case, yellow and blue are opponent colors, so a yellow flash can cause blue afterimages.

Question 16

As a result of the pathway through which visual information travels from the eye to the visual cortex, images seen in the left visual field are received in
A)both the left and right visual cortices.
B)only the right visual cortex.
C)only the left visual cortex.
D)only half of the right visual cortex and half of the left visual cortex.

Accepted Answer

Visual information from the left visual field is processed by the right hemisphere of the brain, including the right visual cortex, due to the crossing of optic nerve fibers at the optic chiasm.

Question 17

The main pathway that  visual signals travel from the eye to the visual cortex is
A)optic nerve - optic chiasm - thalamus - temporal lobe.
B)optic nerve - optic chiasm - thalamus - occipital lobe.
C)optic nerve - thalamus - optic chiasm - temporal lobe.
D)optic nerve - thalamus - optic chiasm - occipital lobe.

Accepted Answer

The correct pathway for visual signals from the eye to the visual cortex involves the optic nerve, optic chiasm, thalamus, and finally the occipital lobe, where the visual cortex is located.

Question 18

If you put a piece of red cellophane over a piece of blue cellophane, you will see purple. This is an example of _____ color mixing.
A)subtractive
B)primary
C)complementary
D)additive

Accepted Answer

Subtractive color mixing occurs when pigments or filters absorb certain wavelengths of light and reflect others. In this case, the red and blue cellophane filters absorb some wavelengths and allow others to pass through, resulting in the perception of purple.

Question 19

The primary visual cortex is located in the   _____ lobes.
A)occipital
B)temporal
C)parietal
D)frontal

Accepted Answer

The primary visual cortex, responsible for processing visual information, is located in the occipital lobes of the brain.

Question 20

If you project a red, a green, and a blue light into space, the point at which the three lights cross will lead to the perception of _____ light.
A)black
B)ultraviolet
C)white
D)infrared

Accepted Answer

When red, green, and blue lights are combined, they produce white light. This is because red, green, and blue are the primary colors of light, and their combination results in the perception of white.
