Relative Size - two objects are similar in size, we percieve the one that casts the smaller retinal image as farther away. Retinal Disparity - a binocular cue for perceiving depth by comparing images from the two eyeballs, the brain computes distance - the greater the disparity (difference) between the two images, the close the object.Ĭonvergence - a binocular cue for perceiving depth the extent to which the eyes converge inward when looking at an object. Monocular Cues - depth cues, such as interposition and linear perspective, available to either eye alone. Visual Cliff - a laboratory device for testing depth perception in infants and young animals.īinocular Cues - depth cues, such as retinal disparity and convergence, that depend on the use of two eyes. *Similarity - a Getalt principle of organization holding that (other things being equal) parts of a stimulus field that are similar to each other tend to be perceived as belonging together as a unit.Ĭontinuity - Gestalt psychology principle which states that the observer tends to see a line or shape as continuing in a particular direction rather than making a turn.Ĭlosure - a Gestalt principle of organization holding that there is an innate tendency to perceive incomplete objects as complete and to close or fill gaps and to perceive asymmetric stimuli as symmetric.Ĭonnectedness - a Gestalt grouping principle elements that are connected to each other group together.ĭepth Perception - the ability to see objects in three dimensions although the images that strike the retina are two-dimensional allows us to judge distance. *Proximity - a Gestalt principle of organization holding that (other things being equal) objects or events that are near to one another (in space or time) are perceived as belonging together as a unit.
*Grouping - the perceptual tendency to organize stimuli into coherent groups. *Gestalt - an organized whole - psychologists emphasized our tendency to integrate pieces of info into meaningful wholes.įigure ground - the organization of the visual field into objects (the figures) that stand out from their surroundings (the ground). Visual Capture - the tendency for vision to dominate the other senses. *Selective Attention - the focusing of conscious awareness on a particular stimulus, as in the cocktail party effect.
