3-D! 68. Monocular cues Cues for perceiving depth based on one eye only. One eye 69. Binocular cues Cues for perceiving depth based on both eyes. Both eyes 70. Pictorial Depth Cues (same as monocular cues) Because it’s used in pictures 71. Linear perspective Monocular depth perception cue, the tendency for parallel lines to appear to converge on each other. Like a road whose sides “meet” in the distance 72. Relative size Monocular 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 appears small will be assumed to be farther away than a mouse that appears big 73. Overlap Monocular depth perception cue, the assumption 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 house 74. Interposition (same as overlap) ^Samesies^ 75. Aerial perspective Monocular depth perception cue, the haziness that surrounds objects that are farther away from the viewer, causing the distance to be perceived as greater. Things in the distance are out of focus, and thus fuzzy 76. Texture gradient Monocular depth perception cue, the tendency 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 parallax Monocular depth perception cue, the perception of motion of objects in which close objects appear to move more quickly than objects that are farther away. Like being in a car. Poles that are farther away slowly crawl across the landscape while poles closer zip by quickly 78. Accommodation As 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 distance 79. Convergence Binocular 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 convergence if objects are distant. How our eyes point together to see something closer to us 80. Binocular disparity Binocular 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 close 81. Feature Detectors Specialized nerve cell in the brain that responds to specific stimuli such as lines, edges, angles or movement. Cells that recognize specific features 82. Muller-Lyer illusion Illusion of line length that is distorted by inward-turning or outward-turning corners on the ends of the lines, causing lines of equal length to appear to be different.
