Perception The process of organizing and interpreting information, enabling us to recognize meaningful objects and events. Visual Capture • The tendency for vision to dominate the other senses. Imax Experience Gestalt Psychology • Gestalt means “an organized whole” • These psychologists emphasize our tendency to integrate pieces of information into meaningful wholes Gestalt Philosophy The whole is greater than the sum of its parts Figure-Ground Relationship • The organization of the visual field into objects (figures) that stand out from their surroundings (ground) Grouping • The perceptual tendency to organize stimuli into groups that we understand Depth Perception • The ability to see objects in three dimensions although the images that strike the retina are two dimensional. • Allows us to judge distance. Visual Cliff How do we transform two-dimensional objects to three-dimensional perception? • Binocular Cues: depth cues that depend on two eyes •Monocular Cues: depth cues that depend on one eye Binocular Cues • Retinal Disparity: a binocular cue for seeing depth. • The closer an object comes to you the greater the disparity is between the two images. Pen together two eyes- try with one Monocular Cues • Interposition: if something is blocking our view, we perceive it as closer. •Relative Size: if we know that two objects are similar in size, the one that looks smaller is farther away. •Relative Clarity: we assume hazy objects are farther away. More Monocular Cues • Texture Gradient: the coarser it looks the closer it is. •Relative Height: things higher in our field of vision, they look farther away •Relative Motion: things that are closer appear to move more quickly. •Liner Perspective: Parallel lines seem to converge with distance. •Light and Shadow: Dimmer objects appear farther away because they reflect less light.
