According to the Gestalt thinkers, the whole is greater than the sum of the parts. From this school of thought emerged the Gestalt’s law of perceptual organization. This set of perceptual principles explains how smaller objects are grouped together to form larger ones. According to Max Wertheimer (1924) “ The fundamental “formula” of Gestalt theory might be expressed in this way : There are wholes, the behavior of which is not determined by that of their individual elements, but where the part-processes are themselves determined by the intrinsic nature of the whole.
The Gestalt psychologists’ primary interest was perception, and they believed that perceptual experiences depend on the patterns formed by stimuli and on the organization of experience.
