1
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.
2
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.
3
Trichromatic (three-color) Theory Cones are sensitive to red, green & blue light
4
Opponent-Process Theory
5
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
6
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
7
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
8
