| 5569572044 | visual capture | the tendency for vision to dominate the other senses | 0 | |
| 5569572045 | visual spectrum | The colors of light that are visible to the human eye. | 1 | |
| 5569572046 | additive color mixing | beams of light combine, adding their wavelengths to the mixture, stimulating more cones, and producing a color lighter than the originals | 2 | |
| 5569572047 | cornea | transparent dome-shaped window covering the front of the eye | 3 | |
| 5569572048 | pupil | adjustale opening in the center of the iris | 4 | |
| 5569572049 | iris | colored muscle that surrounds the pupil and controls the amount of light that enters the eye | 5 | |
| 5569572050 | lens | a transparent structure behind the iris that focuses light rays onto the retina | 6 | |
| 5569572051 | accommodation | the curvature of the lens adjusts to alter visual focus on the retina | 7 | |
| 5569572052 | nearsightedness | nearby objects are seen more clearly than distant objects because distant objects focus in front of the retina | 8 | |
| 5569572053 | farsightedness | distant objects are seen more clearly than near objects because the image of near objects is focused behind the retina | 9 | |
| 5569572054 | vitreous humor | the clear, gel-like mass that fills the space between the lens and the retina | 10 | |
| 5569572055 | retina | light-sensitive inner surface of the eye | 11 | |
| 5569572056 | cones | photoreceptors that are responsible for color vision and visual acuity | 12 | |
| 5569572057 | fovea | concentration of cones in the central region of the retina | 13 | |
| 5569572058 | Young-Helmholtz Theory of Color Vision | According to this theory of color vision, there are three receptors in the retina that are responsible for the perception of color. One receptor is sensitive to the color green, another to the color blue, and a third to the color red. These three colors can then be combined to form any visible color in the spectrum. | 14 | |
| 5569572059 | Opponent-Process Theory | the theory that opposing retinal processes (red-green, yellow-blue, white-black) enable color vision. For example, some cells are stimulated by green and inhibited by red; others are stimulated by red and inhibited by green. | 15 | |
| 5569572060 | afterimages | the firing of cones not used after viewing something steadily in order to bring the visual system back into homeostasis | 16 | |
| 5569572061 | rods | photoreceptors that are responsible for vision in dim light, peripheral vision, and black and white vision | 17 | |
| 5569572062 | bipolar | cells through which a visual stimulus passes after going through the rods and cones and before going to the ganglion cells | 18 | |
| 5569572063 | optic nerve | axons off the ganglion cells (1 million) that carry visual messages to the occipital lobe | 19 | |
| 5569572064 | blind spot | location where optic nerve leaves the retina. It contains no rods or cones | 20 | |
| 5569572065 | optic chiasma | location where half of the information received from each eye crosses over to the opposite side of the cerebrum; depth perception | 21 | |
| 5569572066 | feature detectors | nerve cells in the brain that respond to specific features of the stimulus, such as shape, angle, or movement | 22 | |
| 5569572067 | figure-ground | the organization of the visual field into objects (the figures) that stand out from their surroundings (the ground) | 23 | |
| 5569572068 | similarity | stimuli that are similar tend to be grouped together | 24 | |
| 5569572069 | continuity | lines tend to be seen as following the smoothest path | 25 | |
| 5569572070 | closure | figures with gaps are seen as completed | 26 | |
| 5569572071 | Phi Phenomenon | perceived motion when the object is stationary | 27 | |
| 5569572072 | relative size | a monocular cue for perceiving depth; the smaller retinal image is farther away | 28 | |
| 5569572073 | interposition | monocular visual cue in which two objects are in the same line of vision and one patially conceals the other, indicating that the first object concealed is further away | 29 | |
| 5569572074 | relative clarity | a monocular cue for perceiving depth; hazy objects are farther away than sharp, clear objects | 30 | |
| 5569572075 | texture gradient | a monocular cue for perceiving depth; a gradual change from a coarse distinct texture to a fine, indistinct texture signals increasing distance. objects far away appear smaller and more densely packed | 31 | |
| 5569572076 | relative height | a monocular cue for perceiving depth; objects higher in our field of vision are perceived as farther away | 32 | |
| 5569572077 | relative motion | as we move, objects that are actually stable may appear to move | 33 | |
| 5569572078 | linear perspective | a monocular cue for perceiving depth; the more parallel lines converge, the greater their perceived distance | 34 | |
| 5569572079 | relative brightness | a monocular cue, objects up close appear brighter than objects farther away | 35 |
