5.3 Vision and Perception Quiz

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

• To detect color

• To focus light waves entering the eye

• To control the size of the pupil

• To transmit visual information to the brain

Which part of the eye contains densely packed cones?

• Fovea

• Cornea

• Lens

• Optic nerve

What is the role of rods in the visual system?

• Detecting color

• Providing high spatial resolution

• Functioning in low light conditions

• Focusing light on the retina

What is the optic chiasm?

• The area of the brain that processes visual information

• The part of the eye that detects light

• The point where the optic nerves merge

• The structure that controls pupil size

Which theory explains color vision through opponent pairs?

• Trichromatic theory

• Opponent-process theory

• Gestalt theory

• Retinex theory

What is binocular disparity?

• The ability to see in low light

• The slightly different view each eye receives

• The process of focusing light on the retina

• The perception of color

What is the 'what pathway' responsible for?

• Controlling eye movement

• Perceiving depth

• Object recognition and identification

• Detecting light intensity

What is the main function of the optic nerve?

• To focus light on the retina

• To carry visual information to the brain

• To control the size of the pupil

• To detect color

What is the trichromatic theory of color vision?

• Color vision is based on the intensity of light

• All colors are produced by combining red, green, and blue

• Color is perceived through opponent pairs

• Color is perceived through a single type of photoreceptor

What is the role of the fovea in vision?

• To detect movement

• To provide high spatial resolution

• To control pupil size

• To transmit visual information to the brain
