Chapter 2: Sensation and Perception

Question 1

True or False:

Cones are used for color vision and to sense fine details.

Answer 1

True (Ch. 2)

Question 2

Is the dilator pupillae of the eye activated by parasympathetic or the sympathetic nervous system?

Answer 2

Sympathetic Stimulation (Ch. 2)

Question 3

Is the constrictor pupillae of the eye activated by parasympathetic or the sympathetic nervous system?

Answer 3

Parasympathetic Stimulation (Ch. 2)

Question 4

Which entire lobe of the brain is devoted to just vision?

Answer 4

Occipital Lobe (Ch. 2)

Question 5

True or False:

In the eye, rods are more functional and only allow sensation of light and dark because they all contain a single pigment called rhodopsin.

Answer 5

True (Ch. 2)

*Mnemonic -> Cones are for color vision. Rods function best in “roduced” light.*

Question 6

What is parallel processing of the eye?

Answer 6

Parallel processing is the ability to simultaneously analyze and combine information regarding color, shape, and motion.

Question 7

What does duplexity, or duplicity theory or vision state?

Answer 7

Duplicity theory of vision states that the retina contains two kinds of photoreceptors: those specialized for light-and-dark detection, and those specialized for color detection.

Question 8

Which cell type in the eye detects color?

Answer 8

Cones are responsible for color vision.

Question 9

Which cell type in the eyes detect shape?

Answer 9

Parvocellular Cells

Question 10

Which cell type in the eye detects motion?

Answer 10

Magnocellular Cells

*Mnemonic -> magnocellular cells specialize in motion detection*
