when was the gestalt school of psychology founded
Gestalt psychology The concept of gestalt was first introduced in philosophy and psychology in 1890 by Christian von Ehrenfels (a member of the School of Brentano). The idea of gestalt has its roots in theories by David Hume, Johann Wolfgang von Goethe, Immanuel Kant, David Hartley, and Ernst Mach. Max Wertheimer's unique contribution was to insist that the "gestalt" is perceptually primary, defining the parts it was composed from, rather than being a secondary quality that emerges from those parts, as von Ehrenfels's earlier Gestalt-QualitÃ¤t had been.[citation needed]
John B. Watson John Broadus Watson (January 9, 1878 â€“ September 25, 1958) was an American psychologist who established the psychological school of behaviorism. Watson promoted a change in psychology through his address Psychology as the Behaviorist Views it, which was given at Columbia University in 1913.[3] Through his behaviorist approach, Watson conducted research on animal behavior, child rearing, and advertising. In addition, he conducted the controversial "Little Albert" experiment and the Kerplunk experiment. Watson popularized the use of the scientific theory with behaviorism.[4] He was also editor of Psychological Review from 1910 to 1915.[5] A Review of General Psychology survey, published in 2002, ranked Watson as the 17th most cited psychologist of the 20th century.[6]
