1 Gestalt Psychology Chapter 12 Cognitive Psychology, Third Edition by Kathleen M. Galotti Copyright © 2004 by Wadsworth Publishing, a division of Thomson Learning

2 The Gestalt revolt Around 1912…. Structuralism in waning, functionalism gaining ground Watson begins attack on Wundt and Titchener (1912) People becoming aware of Thorndike’s and Pavlov’s animal research Psychoanalysis 10 years old In Germany… Gestalt revolt Revolt against Wundt

3 The Gestalt revolt A hypothetical debate: Describe what you see (on the table) Wundt Consciousness made up of sensory elements Gestaltists Consciousness can not be reduced to elements The whole is different from the sum of its parts.

4 More to perception than meets the eye Perception goes beyond the sensory elements Elements can be put together in ways other than just mechanical association; perception is not passive These elements are only physical data coming to the sense organs, where the mind codes and interprets them The Gestalt revolt

5 Sensation vs. Perception Kassin, S. (2001). Psychology, third edition. Upper Saddle River, NJ: Prentice Hall.

6 James Phenomenology A new introspective method: Uncorrected observation (no trained observers) Experience not analyzed into elements The Gestalt revolt

7 Another important influence… The changing zeitgeist in physics Physics moving away from atomism to fields of force

8 The phi phenomenon: A challenge to Wundtian psychology Wertheimer's 1910 research Research idea Idea came to him while riding a train Apparent movement: Why do we see movement when no actual physical motion occurs? Stroboscope

9 The phi phenomenon: A challenge to Wundtian psychology Stimulus: two points of light being flashed sequentially Wundt’s prediction: perception of two successive points of light Reality: the perception was of a moving light when in fact the lights were not moving Presented a challenge that the associationistic, elementistic psychology of Wundt could not meet

10 Illusory contours

11 Bistable figures

12 1912: Wertheimer published results Article indicates formal start of Gestalt school 1933: fled Germany The phi phenomenon

13 Founders Wertheimer, Koffka, and Kohler – 1920s “The whole differs from the sum of its parts” Perception is not built up from sensations but is a result of perceptual organization We use heuristics to make “best guesses” about the identity of stimuli Gestalt Psychology

14 1922: article published in American journal “Perception” in title led to misunderstanding that this was the sole interest of Gestaltists Gestalt movement actually had a broader concern Problems of thinking and learning and all aspects of conscious experience Kurt Koffka ( )

15 Wolfgang Köhler ( ) Spokesperson for school of thought Trained with Max Planck Studied chimpanzees 1935: left Germany due to anti-Nazi activities Books became standard works of Gestalt theory Suggested Gestalt theory as general law of nature

16 Principles of Perceptual Organization We perceive wholes, not clusters of sensations Elements interact to create a “new” whole The whole is different from the sum of its parts Underlying premise: Perceptual organization occurs instantly and is inevitable Organizing principles not dependent on: higher mental processes past experience

17 Size Constancy Tendency to view an object as constant in size despite changes in the size of the retinal image. Perceptual Constancies

18 Shape Constancy Tendency to see an object as keeping its form despite changes in orientation. Perceptual Constancies Kassin, S. (2001). Psychology, third edition. Upper Saddle River, NJ: Prentice Hall.

19 Similarity Principles of Perceptual Organization

20 Proximity Principles of Perceptual Organization

21 Principles of Perceptual Organization Closure

22 Good continuation Principles of Perceptual Organization

23 Common fate Principles of Perceptual Organization

24 Principles of Perceptual Organization Figure/Ground

25 Figure/Ground Failing to divide figure from ground

26

27 The nature of the Gestalt revolt Demanded complete revision of psychology Support for new view Phi phenomena Perceptual constancy Attempts at analysis destroy the perception or whole (Gestalt)

28 Gestalt studies of learning Köhler: intelligence in apes

29 Gestalt studies of learning: insight and the mentality of apes Solving the problem: Could the chimp see the “whole” problem? Would proximity of objects influence solution of problem? Insight Spontaneous understanding of relationships

30 The spread of Gestalt psychology Mid-1920’s (Germany) A coherent and dominant school in Germany Attracting students from around the world 1933 Nazi regime: shift of Gestalt psychology to the United States

31 Slow acceptance in the united states Behaviorism was at its peak A language barrier Belief that Gestalt psychology dealt solely with perception Wertheimer, Köhler, and Koffka at small colleges without graduate programs, thus no graduate research assistants The spread of Gestalt psychology

32 Slow acceptance in the united states Gestalt focus of protest (Wundt) no longer of concern in U.S. The word “Gestalt” Had no direct translation in English Therefore, purpose of movement not obvious The spread of Gestalt psychology

33 Both occurred independently of one another, but… both started by opposing Wundt’s focus on sensory elements. Ended up opposing each other Value of consciousness Gestalt psychologists Accepted it Criticized attempt to reduce it to elements Behavioral psychologists Refused it entirely The Gestalt vs. the Behaviorism Revolutions

34 The battle with behaviorism Gestalt criticisms of its new target Reductionistic and atomistic Deals with artificial abstractions (S-R units) Denies the validity of introspection Eliminates consciousness Would make psychology no more than a collection of animal research Conflicts between proponents of the two schools grew increasingly emotional and personal

35 Criticisms of Gestalt psychology Organization of perceptual processes accepted as fact rather than studied scientifically Basic concepts and terms are not defined with sufficient rigor Too preoccupied with theory at the expense of research and empirical support Quality of Gestalt experimental work is inferior to that of the behaviorists Research lacks adequate controls Its unquantified data elude statistical analysis Insight learning: not replicable Poorly defined physiological assumptions

36 Gestalt rebuttals A young science’s explanation and definitions are necessarily incomplete; Gestalt research is exploratory Incomplete is not the same vague Has from the beginning emphasized experimentation Has engendered a considerable amount of research Qualitative results take precedence over quantitative ones

37 Contributions of Gestalt psychology Permanent imprint on psychology Influenced work in perception, learning, thinking, personality, social psychology, and motivation Retained its identity, not absorbed by the mainstream as was behaviorism Broke ground for cognitive movement Fostered interest in consciousness as a legitimate problem for psychology
