perceptual organization
Question | Answer |
---|---|
Gestalt | an organized whole |
Gestalt psychologists | emphasized our tendency to integrate pieces of information into meaningful wholes |
Figure-ground | the organization of the visual field into objects (figures) that stand out from their surroundings (background) |
Grouping | the perceptual tendency to organize stimuli into coherent groups |
Depth perception | the ability to see objects in 3D although the image that strikes the retina are 2 dimensional; allows us to judge distance |
Visual cliff | a laboratory device for testing depth perception in infants and young animals |
Binocular cues | depth cues, such as retinal disparity, that depend on the use of two eyes |
Retinal disparity | binocular cue for perceiving depth; distance between two images- by comparing images from the two eyeballs, the brain computes distance- the greater disparity (difference) between the two images, the closer the object |
Monocular cues | depth cues such as interposition and linear perspective, available to either eye alone. |
Perceptual constancy | perceiving objects as unchanging even as illumination and retinal images change |
Color constancy | perceiving familiar objects as having consisten color, even if changing illumination alters the wavelengths |
