Question 1

Which of the following best describes the difference between sensation and perception?

Accepted Answer

Sensation is the biological process of transducing physical stimuli into neural code, while perception is the cognitive process of understanding sensory information.

Question 2

A researcher presents a faint sound to a participant, who reports hearing it even though no sound was actually played. According to signal detection theory, what is this response called?

Accepted Answer

False Alarm

Question 3

Which structure in the eye is responsible for changing its shape to focus light onto the retina?

Accepted Answer

Lens

Question 4

If a person can detect a candle flame from 30 miles away on a dark night, this is an example of which concept?

Accepted Answer

Absolute threshold

Question 5

Which formula represents Fechner's Law, relating stimulus intensity to perceived intensity?

Accepted Answer

$S = k \log I$

Question 6

A person is exposed to a constant smell in a room and eventually stops noticing it. What psychological phenomenon does this illustrate?

Accepted Answer

Sensory adaptation

Question 7

Which part of the eye contains photoreceptors that transduce light into neural impulses?

Accepted Answer

Retina

Question 8

In the context of taste, which of the following is true?

Accepted Answer

Taste involves chemical compounds binding to taste buds on the tongue.

Question 9

Which scenario best illustrates the concept of priming in perception?

Accepted Answer

A person is more likely to recognize a word after seeing it previously, even if briefly.

Question 10

What is the main function of the optic nerve?

Accepted Answer

To transmit visual information from the eye to the brain

Question 11

A subject is presented with two weights: one weighing 100g and another 105g. The subject can just barely tell the difference. What concept does this scenario illustrate?

Accepted Answer

Difference threshold (just noticeable difference)

Question 12

Which pathway in the brain is primarily responsible for processing object location and spatial configurations?

Accepted Answer

Dorsal pathway

Question 13

Which of the following best describes transduction in the context of hearing?

Accepted Answer

Sound energy is converted into neural impulses in the cochlea.

Question 14

If a person is exposed to a stimulus below their absolute threshold and it influences their behavior, what is this called?

Accepted Answer

Subliminal perception

Question 15

Which of the following is NOT a sense involved in sensation as described in the study materials?

Accepted Answer

Imagination

Question 16

A person is asked to report whether a faint stimulus is present or not. Which two processes does signal detection theory say are involved in their response?

Accepted Answer

Sensory process and decision process

Question 17

Which of the following best explains why illusions can occur in perception?

Accepted Answer

Perception can be dissociated from sensation, leading to misinterpretation of sensory information.

Question 18

Which equation would you use to calculate the just noticeable difference (JND) according to Weber's Law?

Accepted Answer

$\Delta I = kI$

Question 19

Which part of the eye adjusts the size of the pupil in response to light intensity?

Accepted Answer

Iris

Question 20

A person is able to see colors only in daylight but not in dim light. Which type of photoreceptor is primarily responsible for this ability?

Accepted Answer

Cones
