Understanding Vision and Perception

What is the primary function of the cornea in the eye?

• To detect color

• To focus light onto the retina

• To convert light into electrical signals

• To control the amount of light entering the eye

What is the main difference between sensation and perception?

• Sensation involves the brain, perception involves the eyes

• Sensation is the interpretation of signals, perception is the detection of light

• Sensation is conscious, perception is unconscious

• Sensation is the detection of light, perception is the interpretation of signals

Which type of photoreceptor cell is responsible for color detection?

• Opsins

• Rods

• Cones

• Ganglion cells

What happens to the retinal molecule when it absorbs a photon?

• It changes from trans to cis configuration

• It changes from cis to trans configuration

• It becomes inactive

• It breaks down into vitamin A

What is the role of the optic nerve in vision?

• To focus light onto the retina

• To control the amount of light entering the eye

• To convert light into electrical signals

• To transmit visual information to the brain

Which area of the visual cortex is primarily responsible for processing color?

• V5

• V2

• V1

• V4

What does the Gestalt principle of closure refer to?

• The tendency to see objects as a whole rather than in parts

• The ability to distinguish an object from its background

• The perception of objects moving in the same direction as a single unit

• The tendency to follow visual lines or sequences

How does the principle of proximity affect perception?

• It groups objects based on their movement

• It groups objects based on their shape

• It groups objects based on their color

• It groups objects based on their closeness to each other

Which Gestalt principle explains why we see a flock of geese as a single unit?

• Closure

• Common fate

• Proximity

• Similarity

What is the critical period in visual development?

• A time when vision is lost if not used

• A time when color vision is established

• A time when visual abilities are fully developed

• A time when early visual experiences guide brain development
