Q41.
How can visual perception be divided into stages?

a.

Sensing and interpreting

b.

Receiving and transmitting

c.

Focusing and processing

d.

Analyzing and perceiving

Discuss
Answer: (a).Sensing and interpreting Explanation:Visual perception can be divided into two stages: the physical reception of the stimulus and the processing and interpretation of that stimulus.
Q42.
What is the function of the cornea and lens in the eye?

a.

To detect light

b.

To focus light onto the retina

c.

To transmit electrical signals to the brain

d.

To transform light into electrical energy

Discuss
Answer: (b).To focus light onto the retina Explanation:The cornea and lens at the front of the eye focus the light into a sharp image on the back of the eye, which is the retina.
Q43.
Which type of photoreceptor allows us to see under low levels of illumination?

a.

Rods

b.

Cones

c.

Cornea

d.

Lens

Discuss
Answer: (a).Rods Explanation:Rods are highly sensitive to light and allow us to see under low levels of illumination.
Q44.
What is the reason for temporary blindness when moving from a darkened room into sunlight?

a.

Rods are suppressed by the cones.

b.

Cones are saturated by sudden light.

c.

The cornea and lens become less effective.

d.

The fovea is overloaded with images.

Discuss
Answer: (b).Cones are saturated by sudden light. Explanation:Temporary blindness occurs when moving from a darkened room into sunlight because the rods, which are active in low light, become saturated by the sudden increase in light.
Q45.
Where are the cones mainly concentrated in the eye?

a.

Towards the edges of the retina

b.

In the fovea, a small area of the retina

c.

In the cornea and lens

d.

In the rods

Discuss
Answer: (b).In the fovea, a small area of the retina Explanation:Cones, which allow color vision, are mainly concentrated on the fovea, a small area of the retina.
Q46.
What is the blind spot in the eye?

a.

An area where the optic nerve exits the eye

b.

A region with no rods or cones

c.

The fovea, where rods and cones are concentrated

d.

A spot on the cornea that lacks sensitivity to light

Discuss
Answer: (b).A region with no rods or cones Explanation:The blind spot is an area in the retina where there are no rods or cones.
Q47.
What are the two types of specialized nerve cells in the retina?

a.

Rods and cones

b.

X-cells and Y-cells

c.

Ganglion cells and photoreceptors

d.

Cornea and lens

Discuss
Answer: (b).X-cells and Y-cells Explanation:The retina has two types of specialized nerve cells called ganglion cells: X-cells, which are concentrated in the fovea and responsible for early pattern detection, and Y-cells, which are more widely distributed and responsible for early movement detection.
Q48.
What does visual perception involve?

a.

Filtering and processing of received information

b.

Physical reception of the stimulus from the outside world

c.

Transformation of light into electrical energy

d.

Detection of changes in peripheral vision

Discuss
Answer: (a).Filtering and processing of received information Explanation:Visual perception involves filtering the received information and passing it to processing elements for recognizing coherent scenes, determining distances, and differentiating color.
Q49.
Which aspects of visual perception are crucial for the design of visual interfaces?

a.

Size and depth perception

b.

Brightness and color differentiation

c.

Pattern detection and movement detection

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:Size and depth perception, brightness, and color differentiation are all crucial aspects of visual perception that impact the design of effective visual interfaces.
Q50.
How does the visual system interpret images to determine size and distance?

a.

By analyzing the upside-down image formed on the retina

b.

By calculating the visual angle between two lines on the retina

c.

By comparing the appearance of similar objects of different sizes

d.

By judging the distance between objects and the eye

Discuss
Answer: (b).By calculating the visual angle between two lines on the retina Explanation:The visual system determines size and distance by calculating the visual angle, which is the angle between two lines drawn from the top and bottom of the object to a central point on the front of the eye.
