Perceptual Organization: Gestalt an organized whole tendency to integrate pieces of information into meaningful wholes

Perceptual Organization Figure and Ground organization of the visual field into objects (figures) that stand out from their surroundings (ground)

Perceptual Organization Grouping the perceptual tendency to organize stimuli into coherent groups

Perceptual Organization: Grouping Principles

Perceptual Organization: (Closure) Gestalt grouping principles are at work here.

Perceptual Organization Depth Perception (seeing objects in 3D) Binocular cues Retinal disparity: Brain compares perception of both eyes for close objects Monocular cues Distance of object determines which is in effect

Perceptual Organization Monocular Cues relative size smaller image is more distant interposition object that partially blocks another perceived as closer relative clarity hazy object seen as more distant texture coarse --> close fine --> distant

Perceptual Organization Monocular Cues (cont.) relative height higher objects seen as more distant relative motion closer objects seem to move faster linear perspective parallel lines converge with distance Light and shadow the darker the farther away

Perceptual Organization Perceptual Adaptation: our brains ability to change its ideas and expectations about how things should be

Perceptual Organization: Based on many factors: experience culture emotions beliefs context individual motivation perceptual sets
