Gestalt psychology Characterising Gestalt psychology Rise in Germany Moving to the USA Demise and legacies The point: Is the success of a school largely a function of the quality of its ideas…? Alan Collins, Lancaster University Characterising Gestalt psychology Period: 1890-1967 but main period 1911-mid 1930s. ‘Gestalt’ the idea of unified form Aimed to understand what it is that people perceive and what the experiences of perception and learning are Key practitioners: Kohler, Koffka, Wertheimer .. But also Lewin and others Alan Collins, Lancaster University Characterising Gestalt The idea of ‘form’ (Mach) A table has a “form quality” (Gestaltqualitäten) that persists when sensations change - e.g different lighting.

These were also constituting terms of educated middle-class ideology and self-concept in the Weimar period.” (Ash) “… the Gestalt theorists were indeed in tune with the times [as became clear] when others laid claim to the Gestalt concept.” (Ash, 1995, p. 307) Alan Collins, Lancaster University In Germany pre-1914 themes made sharper by WWI mechanistic science ... What place for human values? Doubts over human rationality … death on a huge scale rapid industrialisation and rise of ‘technologies’: more efficient killing? superficiality of modernity devaluing of academic life & threats to elite culture Gestalt psychology appeared to be. a constructive response to many of these fears consistent with wider philosophy of holism and the room it allowed for both science/facts and values (Harrington, 1996) Alan Collins, Lancaster University In addition, Factors such as familiarity with the new physics Wertheimer & Einstein … lifelong friends Kohler: engagement with ideas of Planck & Boltzmann competent in areas outside psychology e.g. philosophy, maths comfortable as scientists Alan Collins, Lancaster University Gestalt psychology: resisted mechanistic science in its emphasis on holism resisted mechanics in adopting the new physics explicitly placed values at centre of study knowledge was not given over entirely to the physical sciences But also attacks for not going far enough e.g. Kreuger on emotion, Jaensch on ‘will’, ‘purpose’. Alan Collins, Lancaster University A verdict … Gestalt psychology richly embedded in and resonant with German culture of early C20 Also ‘Gestalt psychology ... did have an unusual degree of institutional and intellectual coherence. It was a full-bloodied attempt to establish psychology as a science by a reexamination of philosophy and hence of the foundations of the sciences in general, and it was not just an attempt to impose the methodological prescriptions supposedly characteristic of the physical sciences.’ Smith, 1997, p681 Alan Collins, Lancaster University Gestalt psychology in the USA USA as key in early C20 psychology, (O’Donnell, 1985) Movement of major theorists Alan Collins, Lancaster University Koffka: 1920s Smith College, New England 1933 Nazi Law on retirement of non-Aryan and politically suspect state officials 15 psychology profs, 6 lost jobs Wertheimer, New York, 1933 Kohler, Swarthmore, 1935 Lewin, Cornell, 1933 … yet comparatively less successful in USA (Henle, 1977, Ash 1995 but see Sokal, 1984) Alan Collins, Lancaster University Challenges in the USA Classical and Neo-Behaviorism place of phenomenology science: prediction & control Application of knowledge Individual lives of major figures Koffka, Wertheimer, Lewin all dead by 1947 few if excellent students … ‘lack of manpower’ (Ash, 1995) Alan Collins, Lancaster University Legacies? Ideas, topics & findings … well-formedness in perception problem-solving & insight (e.g. Duncker, 1945) purpose in behaviour (e.g. Tolman) life space/social field The Place of Value in a World of Fact (Kohler, 1938) Alan Collins, Lancaster University What might reflection on all this tell us? What enduring psychological issues are apparent when considering Gestalt ideas Is the rise & demise of scientific schools of thought or research largely attributable to the quality of the ideas making up that approach? What ideas in Gestalt psychology challenge or are inconsistent with much of today’s cognitive/social/neuro psychology? Is science only about theories & facts? Should science only be about facts? Can science only be about producing facts? Etc.! Alan Collins, Lancaster University
