3-D!68. Monocular cuesCues for perceiving depth based on one eye only.One eye69. Binocular cuesCues for perceiving depth based on both eyes.Both eyes70. Pictorial Depth Cues(same as monocular cues)Because it’s used in pictures71. Linear perspectiveMonocular depth perception cue, thetendency for parallel lines to appear to converge on each other.Like a road whose sides “meet” in the distance72. Relative sizeMonocular depth perception cue, perception that occurs when objects that a person expects to be of a certain size appear to be small and are, therefore, assumed to be much farther away.An elephant that appearssmall will be assumed to be farther away than a mouse that appears big73. OverlapMonocular depth perception cue, theassumption that an object that appears to be blocking part of another object is in front of the second object and closer to the viewer. If a picture shows a tree that obscures some of a house, that tree is closer and in front of the house74. Interposition(same as overlap)^Samesies^75. Aerial perspectiveMonocular depth perception cue, thehaziness that surrounds objects thatare farther away from the viewer, causing the distance to be perceivedas greater.Things in the distance are out of focus, and thus fuzzy76. Texture gradientMonocular depth perception cue, thetendency for textured surfaces to appear to become smaller and finer as distance from the viewer increases.Things close to you are detailed, things farther away are smaller and less detailed
77. Motion parallaxMonocular depth perception cue, theperception of motion of objects in which close objects appear to move more quickly than objects that are farther away.Like being in a car. Polesthat are farther away slowly crawl across the landscape while poles closer zip by quickly78. AccommodationAs a monocular cue of depth perception, the brain’s use of information about the changing thickness of the lens of the eye in response to looking at objects that are close or far away.When our eyes change the shape of our lens, it sends information to the brain about distance79. ConvergenceBinocular depth perception cue, the rotation of the two eyes in their sockets to focus on a single object, resulting in greater convergence for closer objects and less convergenceif objects are distant.How our eyes point together to see something closer to us80. Binocular disparityBinocular depth perception cue, the difference in images between the two eyes, which is greater for objects that are close and smaller for distant objects.If the images between the eyes are very different, the object is close81. Feature DetectorsSpecialized nerve cell in the brain that responds to specific stimuli such as lines, edges, angles or movement.Cells that recognize specific features82. Muller-Lyer illusionIllusion of line length that is distortedby inward-turning or outward-turningcorners on the ends of the lines, causing lines of equal length to appear to be different.
