Question 1

Which of the following best describes the process of transduction in sensory systems?

Accepted Answer

The transformation of physical energy from the outside world into neural impulses.

Question 2

According to Weber's Law, the just noticeable difference (JND) between two stimuli is:

Accepted Answer

A constant proportion of the original stimulus intensity.

Question 3

Signal Detection Theory posits that whether a stimulus is perceived depends on:

Accepted Answer

Both the sensory experience and the judgment made by the subject.

Question 4

Which Gestalt principle explains why we perceive objects that look alike as grouped together?

Accepted Answer

Similarity

Question 5

A person is able to recognize a friend's voice in a crowded room. This is an example of:

Accepted Answer

Top-down processing

Question 6

Which of the following statements about rods and cones is correct?

Accepted Answer

Rods are located in the peripheral retina and are highly sensitive in low light.

Question 7

Which theory maintains that colour vision is determined by three different types of cones sensitive to short, medium, and long wavelengths of light?

Accepted Answer

Trichromatic theory

Question 8

Damage to the dorsal stream ('where/how' pathway) in the brain is most likely to result in:

Accepted Answer

Impaired ability to judge spatial relationships and guide movements.

Question 9

Which of the following best illustrates perceptual constancy?

Accepted Answer

Recognizing a car as the same object whether it is in sunlight or shade.

Question 10

If a person is unable to recognize faces but can identify objects, which brain region is most likely affected?

Accepted Answer

Temporal lobe face recognition area

Question 11

Which process is responsible for reducing activity in sensory receptors with repeated exposure to a stimulus?

Accepted Answer

Sensory adaptation

Question 12

A driver fails to notice a pedestrian while focusing on a traffic light. This is an example of:

Accepted Answer

Inattentional blindness

Question 13

Which of the following is true about the optic chiasm?

Accepted Answer

It is the point where visual information from both eyes crosses over to the opposite side of the brain.

Question 14

Which formula represents Weber's Law for just noticeable difference (JND)?

Accepted Answer

$$ \Delta I = kI $$

Question 15

Which pathway in the brain is primarily responsible for object recognition?

Accepted Answer

Ventral stream

Question 16

A person adds salt to their food and notices the taste change. This is an example of detecting:

Accepted Answer

Difference threshold

Question 17

Which of the following best describes priming in perception?

Accepted Answer

Exposure to a stimulus can influence an individual's later responses to the same stimulus or one that is related to it.

Question 18

Which of the following is NOT a function of the thalamus in visual processing?

Accepted Answer

Processing auditory information.

Question 19

Which of the following is a real-world example of top-down processing?

Accepted Answer

Using prior knowledge to interpret a familiar voice in a noisy environment.

Question 20

Which statement about depth perception is correct?

Accepted Answer

It allows us to judge distances and spatial relationships.
