11.1 Vision Flashcards
pluses of electromagnetic energy are interpreted as color
vision
grayscale and peripheral vision
rods
colors
cones
lightwaves must activate what to start a chain reaction to see color?
it must activate the back of the eye first, the cones
what is the chain reaction to see color in order?
retina –> rods + cones cluster (fovea) –> bipolar –> ganglium –> optic nerve –> thalamus –> occipital lobe
helps you recognize various features of various objects (located in the occipital lobe)
feature receptors
ability to recognize things from different angles and colors
perceptual constancy
simultaneously perceiving speed, distance, texture, color, etc.
parallel processing
see colors in combinations of mixing blue/green/red receptors
trichromatic theory
some receptors eliminating opposing colors that share the same pathway in the retina and thalamus
opponent process theory
