Psychology 107 quiz 4. 2 exam prep / quiz notes. We define light as the wavelength that stimulate our receptors. On a dark night, you see a faint star slightly to the periphery of your eyes. Then why you focus on it with you fovea, it disappears. It can be caused by heredity, disease, or exposure to loud noises. The rods of the retina are more numerous in the periphery than in the fovea. Located mostly in the peripheral areas of the retina. When certain neurons increase their firing rate, you see green. According to opponent- process theory of color vision, what do you see when they inhibit their firing? red. An application of capsaicin to the skin or muscles causes first a burning sensation and then a prolonged decrease in pain sensations. Capsaicin releases pain transmitters faster than the brain can resynthesize them.
