Question 1

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

Accepted Answer

Sensation is the process of detecting and encoding sensory stimuli as neural signals, while perception is the process of selecting, organizing, and interpreting those signals.

Question 2

A researcher flashes a light at varying intensities to determine the minimum level at which a participant can detect it 50% of the time. What concept is being tested?

Accepted Answer

Absolute threshold

Question 3

Which scenario best illustrates top-down processing?

Accepted Answer

A person recognizes a familiar face in a crowd based on their expectations and past experiences.

Question 4

In the famous 'gorilla experiment,' participants failed to notice a person in a gorilla suit because their attention was focused elsewhere. This is an example of:

Accepted Answer

Attentional blindness (inattentional blindness)

Question 5

Which of the following best explains why proofreading your own writing can be difficult?

Accepted Answer

Top-down processing causes your brain to fill in gaps based on expectations.

Question 6

A person who cannot recognize familiar faces, but can identify objects, is likely suffering from:

Accepted Answer

Prosopagnosia

Question 7

Which theory of color vision states that the retina contains three types of color receptors, each sensitive to a different wavelength?

Accepted Answer

Trichromatic theory

Question 8

If you stare at a red object for 30 seconds and then look at a blank sheet of paper, you see a greenish afterimage. This supports which theory?

Accepted Answer

Opponent-process theory

Question 9

Which monocular depth cue is illustrated when parallel lines appear to converge as they recede into the distance?

Accepted Answer

Linear perspective

Question 10

A person who can make correct guesses about the visual appearance of objects despite being blind is demonstrating:

Accepted Answer

Blindsight

Question 11

Which Gestalt principle explains why we perceive a Kanizsa square even though no actual square is drawn?

Accepted Answer

Closure

Question 12

The Ponzo illusion tricks our brain into perceiving one object as larger than another by using which depth cue?

Accepted Answer

Linear perspective

Question 13

Which part of the eye is responsible for focusing light and accommodating for near and far objects?

Accepted Answer

Lens

Question 14

Why is it difficult to distinguish colors at night?

Accepted Answer

We are seeing primarily with the rods.

Question 15

Which phenomenon describes the process by which our senses convert physical energy into neural signals?

Accepted Answer

Transduction

Question 16

A pilot fails to notice another plane crossing the runway while preparing to land. This is an example of:

Accepted Answer

Attentional blindness (inattentional blindness)

Question 17

Which of the following best describes sensory adaptation?

Accepted Answer

The process by which we become less sensitive to constant stimuli over time.

Question 18

Which pathway in the brain is primarily responsible for processing visual form and color?

Accepted Answer

The 'what' pathway to the temporal lobe

Question 19

Which illusion demonstrates that people from cultures with fewer straight lines and right angles are less susceptible to certain visual tricks?

Accepted Answer

Müller-Lyer illusion

Question 20

Which equation best represents the calculation of the absolute threshold in psychophysics?

Accepted Answer

$$P_{detect} = \frac{N_{detected}}{N_{trials}}$$
