Document Summary

Whole is different than sum of parts. When you have contrast, the background tends to look further away. Visual illusions that evoke the perception of an edge without a luminance or color change across that edge. Tendency to perceive in a particular way. Predispositions to interpret stimuli in particular ways. Monocular cues size of retinal image depends on distance. Trinocular cues retinal images differ on each eye. Linear perspective narrow parallel lines perceived further than wide ones. Texture gradient denser and less distinct texture perceived as further. Relative size when expected to be same size, smaller objects perceived further. Height in plane objects low in field perceived closer, objects high in field perceived. Shading and light patterns of light and shadows suggest depth. Visually perceived images that differ from objective reality. Can reveal how brain normally organizes and interprets sensory stimulation. Excessive stimulation of brightness, color, size, position, and movement on eyes and brain.
