Question 1

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

Accepted Answer

Sensation is the process where our senses turn physical energy from the world into signals the brain can understand, while perception is the mental process of making sense of sensory information.

Accepted Answer

Hit

Question 3

An animal can hear sounds at a lower intensity than a human. This is an example of which concept?

Accepted Answer

Lower stimulus threshold

Question 4

Which part of the eye is responsible for controlling the amount of light that enters?

Accepted Answer

Iris

Question 5

A person is able to smell a candle but cannot name the object when shown a picture of it. This is an example of:

Accepted Answer

Anomia

Question 6

Which theory explains how three types of cones in the retina respond to different wavelengths of light to produce color vision?

Accepted Answer

Trichromatic theory

Question 7

If a person sees a dress as blue and black while another sees it as gold and white, this difference is best explained by:

Accepted Answer

Differences in perception based on prior experiences

Question 8

Which pathway in the brain is primarily responsible for identifying what an object is?

Accepted Answer

Question 9

Which of the following is NOT a function of rods in the retina?

Accepted Answer

Question 10

A researcher wants to measure the smallest difference in salt concentration that a person can detect in soup. Which concept is being tested?

Accepted Answer

Question 11

Which equation best represents the relationship between stimulus intensity ($$I) $$and the just noticeable difference ($$\Delta I) $$according to Weber's Law?

Accepted Answer

$$\Delta I = k \cdot I$$

Question 12

Which of the following is an example of top-down processing?

Accepted Answer

Question 13

Which part of the brain acts as a relay center for sensory information before it reaches the cortex?

Accepted Answer

Question 14

A person is shown a series of faces and asked to identify them. Which brain area is most likely involved in this task?

Accepted Answer

Question 15

Which of the following best describes the opponent process theory of color vision?

Accepted Answer

Cones are organized in pairs that only respond to red-green, yellow-blue, and white-black.

Question 16

Which scenario best illustrates a 'false alarm' in signal detection theory?

Accepted Answer

A person reports hearing a sound when none was present.

Question 17

Which of the following is a real-world example of bottom-up processing?

Accepted Answer

Learning to identify an object without prior knowledge by focusing on its features

Question 18

Which visual pathway is primarily involved in determining the location and movement of objects?

Accepted Answer
