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

Accepted Answer

Accepted Answer

Weber's law

Question 3

Which scenario best exemplifies top-down processing?

Accepted Answer

Reading a word with jumbled letters but recognizing it because the first and last letters are in place.

Question 4

According to signal detection theory, which factor does NOT influence whether a stimulus is detected?

Accepted Answer

The color of the stimulus

Question 5

If a person is exposed to a stimulus below their absolute threshold and later makes a choice influenced by that exposure, what psychological phenomenon is this?

Accepted Answer

Priming

Question 6

Which equation best represents Weber's law for just noticeable difference ($$JND) in $$stimulus intensity?

Accepted Answer

$$JND = k \times I$$

Question 7

A student is listening to music while studying. After a while, they stop noticing the background music. What psychological concept does this illustrate?

Accepted Answer

Sensory adaptation

Question 8

Which of the following is an example of perceptual set influencing perception?

Accepted Answer

A person who expects to see a duck in an ambiguous image is more likely to perceive a duck.

Question 9

Which of the following best describes bottom-up processing?

Question 11

Which of the following statements about absolute threshold is correct?
