Question 1

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

Accepted Answer

Sensation is the biological process of detecting physical stimuli from the environment, while perception is the cognitive process of interpreting sensory information.

Question 2

A person is able to detect a candle flame from 30 miles away on a clear night. This scenario is an example of which psychological concept?

Accepted Answer

Absolute threshold

Question 3

According to Weber's Law, the just noticeable difference (JND) for a stimulus is:

Accepted Answer

A constant proportion of the initial stimulus intensity

Question 4

Which pathway in the visual system is primarily responsible for object recognition?

Accepted Answer

Ventral pathway (occipitotemporal)

Question 5

A patient can accurately reach for objects but cannot identify them by sight. This deficit most likely results from damage to which brain region?

Accepted Answer

Occipitotemporal (ventral) pathway

Question 6

Signal detection theory is used to explain how we:

Accepted Answer

Detect a stimulus in the presence of uncertainty

Question 7

Which of the following is an example of the difference threshold?

Accepted Answer

Noticing the volume increase when your friend turns up the music by one notch

Question 8

The process by which sensory receptors convert physical energy into neural signals is called:

Accepted Answer

Transduction

Question 9

Which of the following best illustrates top-down processing in perception?

Accepted Answer

Recognizing your friend's face in a crowd based on your memory

Question 10

A person with prosopagnosia is most likely to have difficulty with which of the following tasks?

Accepted Answer

Identifying familiar faces

Question 11

Which of the following equations represents Weber's Law?

Accepted Answer

$$ \frac{\Delta I}{I} = k $$

Question 12

In the visual system, which type of photoreceptor is primarily responsible for color vision and is concentrated in the fovea?

Accepted Answer

Cones

Question 13

Which of the following is an example of bottom-up processing?

Accepted Answer

Perceiving a shape based solely on the arrangement of lines and edges

Question 14

If a person can detect a difference between 10g and 12g weights, according to Weber's Law, what is the minimum difference they should be able to detect for a 100g weight?

Accepted Answer

10g

Question 15

Which of the following best describes the function of the dorsal visual pathway?

Accepted Answer

Object location and spatial processing

Question 16

A person is exposed to a faint sound repeatedly and eventually stops noticing it. This phenomenon is best explained by:

Accepted Answer

Sensory adaptation

Question 17

Which of the following is NOT an example of an absolute threshold?

Accepted Answer

Noticing the difference between two similar shades of blue

Question 18

Which of the following best illustrates the concept of figure-ground in perception?

Accepted Answer

Seeing a vase or two faces in a classic optical illusion

Question 19

Damage to which area is most likely to result in problems with spatial localization but not object identification?

Accepted Answer

Dorsal pathway (occipitoparietal)

Question 20

Which of the following best describes the process of transduction in the visual system?

Accepted Answer

Conversion of light energy into neural signals by photoreceptors
