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

Accepted Answer

Recognizing familiar faces, even though they can see them clearly.

Question 3

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

Accepted Answer

Dependent on the initial intensity of the stimulus.

Question 4

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

Accepted Answer

The minimum intensity of a sound required for it to be detected 50% of the time.

Question 5

Signal detection theory is primarily concerned with:

Accepted Answer

How decision making takes place in the presence of uncertain stimuli.

Question 6

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

Accepted Answer

Dorsal pathway (occipitoparietal)

Question 7

If a person can detect a teaspoon of sugar in a gallon of water, this is an example of:

Accepted Answer

An absolute threshold for taste.

Question 8

Which of the following best illustrates the concept of perceptual ambiguity?

Accepted Answer

The 'dress' illusion, where people perceive the same dress as different colors.

Question 9

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

Accepted Answer

$JND = k \times I$

Question 10

Which of the following is NOT a sense typically measured by absolute thresholds?

Accepted Answer

Memory

Question 11

A researcher wants to measure the smallest difference in brightness that a participant can detect between two lights. Which threshold is being measured?

Accepted Answer

Difference threshold

Question 12

Which of the following best describes the flow of sensory information for vision?

Accepted Answer

Retina > thalamus > cortex

Question 13

Which scenario best demonstrates the dissociation between sensation and perception?

Accepted Answer

A person can hear a sound but cannot identify its source.

Question 14

Which of the following is a real-world application of signal detection theory?

Accepted Answer

A radiologist deciding whether a spot on an X-ray is a tumor or not.

Question 15

Which pathway is most associated with object recognition and face perception?

Accepted Answer

Ventral pathway

Question 16

A person is able to detect a watch ticking 20 feet away. This is an example of:

Accepted Answer

Absolute threshold for hearing.

Question 17

Which of the following best explains why two people might perceive the same ambiguous image differently?

Accepted Answer

Their prior knowledge and expectations influence perception.

Question 18

Which of the following is a correct statement about the relationship between stimulus intensity and detection probability?

Accepted Answer

As stimulus intensity increases, the probability of detection increases.

Question 19

Which concept is illustrated by the ability to process a stimulus without prior knowledge?

Accepted Answer

Bottom-up processing

Question 20

Which of the following is most likely to be affected in a person with occipitotemporal lesions?

Accepted Answer

Object identification and face perception
