Serial vs. Parallel Processing Serial Processing – Process items one after another – Conscious processing Parallel processing – Simultaneously processing – Unconscious processing – The brain divides what it sees into four components color, motion, form, and depth. Brain then combines these into one image that you see and comprehend.

Theories of Color Vision Color like all aspects of vision, resides not in the object, but in the theater of our brains. Objects are everything but the color we see.

Trichromatic (three-color) Theory Cones are sensitive to red, green & blue light

Opponent-Process Theory

Color is processed in the thalamus in opponent pairs of color: – Red-green, yellow-blue, black-white – Light that stimulates one half of the pair inhibits the other half

Afterimages If we view colored stimuli for an extended period of time, we will see an afterimage in a complementary color when we view something white. Castle

Colorblindness If missing a pair of receptors, have difficulty seeing those hues – Dichromatic color blindness – can’t see either red/green or blue/yellow – Monochromatic color blindness – can only see shades of gray

Additive vs. Subtractive Color Mixing
