Question 14

Describe the trichromatic, opponent-process, and retinex theories of color vision.

Accepted Answer

Trichromatic: We have three different kinds of cones, each maximally sensitive to different wavelengths of light (corresponding to colors that we see as red, green, and blue). Opponent process: Bipolar cells are excited or inhibited by each member of a pair of complementary colors (yellow-blue, red-green, white-black). Retinex: The cortex compares information from various parts of the retina to determine brightness and color perception for each area.

Accepted Answer

A)   stimulus field
B)   convergence field
C)   receptive field
D)   bipolar areaE) A) and B)
F) A) and C)

Question 16

Cells in the magnocellular path are color insensitive, therefore _____ is also color insensitive.

Accepted Answer

A)   MT
B)   fusiform gyrus
C)   V4
D)   V1E) A) and B)
F) A) and C)

Question 17

Light has entered Joelle's eyes. After being detected by the photoreceptors, the information will be passed on to _____ cells.

Accepted Answer

A)   retina cells
B)   bipolar cells
C)   ganglion cells
D)   spiny cellsE) A) and B)
F) B) and D)

Question 18

B)   the first month of life
C)   any two month period in adult life
D)   the third and fourth months of lifeE) A) and B)
F) All of the above

Question 19

Why do humans perceive faint light better in the periphery of the eye?

Accepted Answer

A)   Receptors in the periphery are closer to the pupil.
B)   The fovea is closer to the retina's blind spot than peripheral receptors.
