The Gestaltists were the first psychologists to systematically study perceptual grouping. According to Gestalt psychologists, the fundamental principle of perceptual grouping is the law of Prägnanz. (The law of Prägnanz is also known as the law of good Gestalt.) "Prägnanz" is a German word that directly translates to "pithiness" and implies salience, conciseness, and orderliness. The law of Prägnanz says that we tend to experience things as regular, orderly, symmetrical, and simple. As Koffka put it, "Of several geometrically possible organizations that one will actually occur which possesses the best, simplest and most stable shape."
