Gestalt psychology

Gestalt psychology, gestaltism, or configurationism is a school of psychology and a theory of perception that emphasises the processing of entire patterns and configurations, and not merely individual components. It emerged in the early twentieth century in Austria and Germany as a rejection of basic principles of Wilhelm Wundt's and Edward Titchener's elementalist and structuralist psychology.

Gestalt psychology is often associated with the adage, "The whole is other than the sum of its parts". In Gestalt theory, information is perceived as wholes rather than disparate parts which are then processed summatively. As used in Gestalt psychology, the German word Gestalt (/ɡəˈʃtælt, -ˈʃtɑːlt/ gə-SHTA(H)LT, German: [ɡəˈʃtalt] ^ⓘ; meaning "form") is interpreted as "pattern" or "configuration".

It differs from Gestalt therapy, which is only peripherally linked to Gestalt psychology.

Max Wertheimer, Kurt Koffka, and Wolfgang Köhler founded Gestalt psychology in the early 20th century. The dominant view in psychology at the time was structuralism, exemplified by the work of Hermann von Helmholtz, Wilhelm Wundt, and Edward B. Titchener. Structuralism was rooted firmly in British empiricism and was based on three closely interrelated theories:

Together, these three theories give rise to the view that the mind constructs all perceptions and abstract thoughts strictly from lower-level sensations, which are related solely by being associated closely in space and time. The Gestaltists took issue with the widespread atomistic view that the aim of psychology should be to break consciousness down into putative basic elements.

In contrast, the Gestalt psychologists believed that breaking psychological phenomena down into smaller parts would not lead to understanding psychology. Instead, they viewed psychological phenomena as organized, structured wholes. They argued that the psychological "whole" has priority and that the "parts" are defined by the structure of the whole, rather than the other way round. Gestalt theories of perception are based on human nature being inclined to understand objects as an entire structure rather than the sum of its parts.

Wertheimer had been a student of Austrian philosopher, Christian von Ehrenfels, a member of the School of Brentano. Von Ehrenfels introduced the concept of Gestalt to philosophy and psychology in 1890, before the advent of Gestalt psychology as such. Von Ehrenfels observed that a perceptual experience, such as perceiving a melody or a shape, is more than the sum of its sensory components. He claimed that, in addition to the sensory elements of the perception, there is something additional that is an element in its own right, despite in some sense being derived from the organization of the component sensory elements. He called it Gestalt-qualität or "form-quality." It is this Gestalt-qualität that, according to von Ehrenfels, allows a tune to be transposed to a new key, using completely different notes, while still retaining its identity. The idea of a Gestalt-qualität has roots in theories by David Hume, Johann Wolfgang von Goethe, Immanuel Kant, David Hartley, and Ernst Mach. Both von Ehrenfels and Edmund Husserl seem to have been inspired by Mach's work Beiträge zur Analyse der Empfindungen (Contributions to the Analysis of Sensations, 1886), in formulating their very similar concepts of gestalt and figural moment, respectively.

By 1914, the first published references to Gestalt theory could be found in a footnote of Gabriele von Wartensleben's application of Gestalt theory to personality. She was a student at Frankfurt Academy for Social Sciences, who interacted deeply with Wertheimer and Köhler.
