Question 1

The Law of Specific Nerve Energies

Answer 1

any energy that is capable of activating neurons will be interpreted by the cortex that those neurons connect with

Question 2

Retinex Theory

Answer 2

argues that color perception is a byproduct of comparing all of the colors available in a visual field

Question 3

Color Constancy

Answer 3

means that, normally, we perceive objects as always being the same color, even if they might actually look very different at different times of day

Question 4

rods

Answer 4

a majority of photoreceptors, they respond primarily to movement

Question 5

cones

Answer 5

a minority of photoreceptors, they respond to color and detail

Question 6

fovea

Answer 6

the midpoint of the retina, where most cones are concentrated, what we use when focusing our visual attention

Question 7

Bipolar/Amacrine/Ganglion cells

Answer 7

cells in front of the retina where initial visual processing begins, pre-processing centers prior to reaching optic nerve

Question 8

Midget Ganglion cells

Answer 8

a cell attached to a single cone in the fovea, 70% of our visual input is processed by these cells

Question 9

Optic nerve

Answer 9

approximately 1 million axons that exit the eye carrying processed visual information to the thalamus
