Question 1

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

Accepted Answer

Sensation is the physiological process of transducing energy from the external world into neural signals, while perception is the cognitive process of interpreting those signals to guide behavior.

Question 2

Which scenario best illustrates the concept of dissociation between sensation and perception?

Accepted Answer

A person can feel heat but cannot identify the source as a stove due to visual agnosia.

Question 3

According to Weber’s Law, the just noticeable difference (JND) is proportional to the initial stimulus intensity. Which equation represents this relationship?

Accepted Answer

$$ \Delta I = kI $$

Question 4

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

Accepted Answer

Hearing a watch ticking 20 feet away in a quiet room.

Question 5

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

Accepted Answer

Difference threshold (just noticeable difference)

Question 6

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

Accepted Answer

Ventral pathway (occipitotemporal)

Question 7

In the context of vision, what is the role of the retina?

Accepted Answer

It transduces light energy into neural signals.

Question 8

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

Accepted Answer

Distinguishing a vase from the background in an ambiguous image.

Question 9

A person is able to localize where a sound is coming from but cannot identify what the sound is. Which visual pathway is likely impaired?

Accepted Answer

Dorsal pathway

Question 10

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

Accepted Answer

Detecting the difference between two weights for touch.

Question 11

Which Gestalt principle explains why we perceive a series of dots as a continuous line?

Accepted Answer

Good continuation

Question 12

If a person can detect a stimulus only 40% of the time, what does this indicate about the stimulus intensity relative to the absolute threshold?

Accepted Answer

The stimulus intensity is below the absolute threshold.

Question 13

Which of the following best describes the process of transduction in sensation?

Accepted Answer

Converting physical energy from the environment into neural signals.

Question 14

A patient with visual agnosia can see objects but cannot recognize them. Which process is impaired?

Accepted Answer

Perception

Question 15

Which of the following is a real-world example of the application of Weber’s Law?

Accepted Answer

Noticing the difference in brightness between two lamps when one is much brighter than the other.

Question 16

Which sensory system is responsible for detecting a wing of a fly dropped on your cheek from 1 cm above?

Accepted Answer

Touch

Question 17

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

Accepted Answer

Object location and spatial configuration

Question 18

A person is asked to identify the location of a sound in a discrimination task. Which pathway is primarily involved?

Accepted Answer

Dorsal pathway

Question 19

Which of the following is an example of sensory adaptation?

Accepted Answer

Becoming less aware of the feeling of your clothes on your skin over time.
