Vision and Perception Quiz

What is the primary function of the cornea in the visual system?

• To control the size of the pupil

• To focus light waves entering the eye

• To detect color

• To transmit visual information to the brain

Which type of photoreceptor is responsible for color vision?

• Bipolar cells

• Rods

• Cones

• Ganglion cells

What is the role of the optic nerve?

• To control the dilation of the pupil

• To detect movement in the visual field

• To carry visual information from the retina to the brain

• To focus light on the retina

What is the 'what pathway' responsible for in visual processing?

• Regulation of pupil size

• Object recognition and identification

• Perception of depth

• Detection of light intensity

According to the trichromatic theory, which colors are the cones sensitive to?

• Yellow, green, blue

• Red, green, blue

• Red, green, yellow

• Red, yellow, blue

What is binocular disparity?

• The perception of color in dim light

• The slightly different view each eye has of the world

• The ability to see in low light conditions

• The process of focusing light on the retina

What is the main function of rods in the visual system?

• To function in low light conditions

• To transmit visual information to the brain

• To detect color

• To provide high spatial resolution

What is the opponent-process theory of color vision?

• Color is perceived through three types of cones

• Color is coded in opponent pairs like black-white and green-red

• Color vision is based on the intensity of light

• Color is perceived through a single type of photoreceptor

What is the purpose of the fovea in the eye?

• To detect movement

• To provide additional focus

• To contain densely packed cones for acute detail

• To control the size of the pupil

What is the function of the optic chiasm?

• To focus light on the retina

• To merge optic nerves from both eyes and direct visual information to the brain

• To control the dilation of the pupil

• To detect color in low light conditions
