Gestalt Psychology

Wiki 

Gestalt psychology or gestaltism (German: Gestalt - "form" or "whole") of the Berlin School is a theory of mind and brain positing that the operational principle of the brain is holistic, parallel, and analog, with self-organizing tendencies, or that the whole is different from the sum of its parts. The Gestalt effectrefers to the form-forming capability of our senses, particularly with respect to the visual recognition of figures and whole forms instead of just a collection of simple lines and curves. In psychology, gestaltism is often opposed to structuralism and Wundt. Often, the phrase "The whole is greater than the sum of the parts" is used when explaining Gestalt theory.
