Week 8

Question 1

Perceptions

Answer 1

3 classes of cone receptors that synapse with parvo RGCs

Question 2

Color wheel/circle

Answer 2

Represents spectral colors and a few no spectral to predict additive color mixture with 2 colors

Question 3

Hue

Answer 3

Corresponds to perception of wavelength. Spectral: Roy g biv, nonspectral: purples

Question 4

Saturation

Answer 4

Corresponds to purity of light. Pure:1 wavelength,desaturates as mix more wavelengths

Question 5

Brightness

Answer 5

Corresponds to intensity of light(#of photons)

Question 6

Additive color mixture

Answer 6

Creates light color

Question 7

Subtractive color mixture

Answer 7

Creates dark color

Question 8

Trichromatic theory

Answer 8

3 primary hues in different amounts can generate all possible colors. Efficient, economical

Question 9

Evidence trichromatic color theory

Answer 9

Additive color mixtures
Forms of color deficiency (dichromatism)
Protonopia: long wavelength out
Deuteranopia: medium wavelength out
Trotanopia: short wavelength out
Cone absorption spectra: 3 classes of cone receptors

Question 10

Operant process theory

Answer 10

4 primary colors are organized into 2 opponent pairs

Question 11

Evidence for opponent process theory

Answer 11

Cross cultural naming
Infant categorization
Colored after images
Opponent/double opponent neurons

Question 12

Reconcile 2 theories?

Answer 12

Wiring diagram relating to cones to RGCs with both excitatory/inhibitatory connections

Question 13

Physical stimulus

Answer 13

Light of varying wavelengths within the visible spectrum. Some moving black/white patterns
