AP Psychology: Sensation & Perception 2

Question 1

What is the absolute threshold in sensation?

Accepted Answer

The minimum stimulation needed to detect a stimulus 50% of the time

Answer

The maximum amount of stimulation a person can tolerate

Answer

The point at which a stimulus becomes painful

Answer

The average intensity of environmental stimuli

Question 2

What is Weber's Law?

Accepted Answer

The just noticeable difference between two stimuli is a constant proportion of the original stimulus

Answer

All senses have the same sensitivity threshold

Answer

Sensory adaptation occurs at a fixed rate for all stimuli

Answer

Perception is directly proportional to stimulus intensity

Question 3

How does the trichromatic theory explain color vision?

Accepted Answer

Three types of cone receptors (red, green, blue) combine to produce all color perceptions

Answer

Color is perceived by a single type of photoreceptor

Answer

Color vision depends on rod cells in the retina

Answer

The brain processes all colors equally without specialized receptors

Question 4

What are Gestalt principles of perception?

Accepted Answer

Rules describing how the brain organizes sensory information into meaningful patterns

Answer

Mathematical formulas for calculating stimulus intensity

Answer

Techniques for improving visual acuity

Answer

Methods for testing hearing sensitivity

Question 5

What is sensory adaptation?

Accepted Answer

Diminished sensitivity to an unchanging stimulus over time

Answer

Increased sensitivity to repeated stimuli

Answer

The ability to detect very faint stimuli

Answer

The brain's preference for novel stimuli

Question 6

What is the difference between monocular and binocular depth cues?

Accepted Answer

Monocular cues require one eye; binocular cues require both eyes working together

Answer

Monocular cues are more accurate than binocular cues

Answer

Binocular cues work only at long distances

Answer

There is no functional difference between them
