Gestalt experiments show that the brain does not act like a sponge (as a passive receiver of information) but actively filters, structures, and matches all incoming information against known patterns to make sense of it. Gestalt theory was proposed by the Austrian psychologist Christian von Ehrenfels (1859-1932) in 1890.
Gestalt Laws of Perceptual OrganizationThe Law of Proximity: Stimulus elements that are closed together tend to be perceived as a group
The Law of Similarity: Similar stimuli tend to be grouped, this tendency can even dominate grouping due to proximity
The Law of Closure: Stimuli tend to be grouped into complete figures
The Law of Good Continuation: Stimuli tend to be grouped as to minimize change or discontinuity
The Law of Symmetry: Regions bound by by symmetrical boarders tend to be perceived as coherent figures
The Law Simplicity: Ambiguous stimuli tend to be resolved in favor of the simplest
