Determines its hue or color - Wavelength, Influences brightness by measuring the amount of light waves - Intensity, Light enters the eye here - pupil, The colored muscle that surrounds and open and closes the pupil - Iris, Focus on incoming rays by changing its curvature - Lens, The light sensitive surface on which the rays focus - retina, The retina contains theses - rods and cones, These let our perceive color - cones, These help you detect black, white and gray - rods, This is the retina's area of central focus - fovea, This sends messages to the brain - optic nerve, Where the optic nerve leaves the eye and there are no receptors which creates this - Blindspot, Area of vision in the brain - Occipital lobe, They provided understanding of the visual system - Hubel and Wiesel, The point at which a stimulus can be detected 50% of the time. - Absolute threshold, The entry level of sensory analysis - Bottom up processing, Analysis of our experiences and expectations - Top-down processing, This law states that intensity of the just noticable difference depends upon how large is the stimulus - Weber's law, The process of incoming rays by changing its curvature - Accommodation, These respond to specific features such as edges, lines, angles and movement - Feature detectors,
