 In Vienna, Otto Glöckel, founder of the world-renowned Vienna School Reform movement and president of the Vienna School Board, offered to fund for the Bühlers a psychological laboratory. After Karl Bühler had lost to Köhler the appointment to the Berlin posts, he ended up assuming in 1923 the directorship of the newly funded Psychological Institute of Vienna. From the Institute the Bühlers became central to Red Vienna culture. They taught at the Pedagogical Academy of Vienna. In addition, she focused on children education and psychological welfare. His interest in language and philosophy brought him closer to Schlick (Wittgenstein’s sister Margaret organized social occasions for Wittgenstein, the Bühlers and the Schlicks to meet) and he encouraged his students to attend Vienna Circle seminars (Egon Brunswick, Elsa Frankel, Marie Jahoda, Paul Lazersfeld, Rudolf Ekstein and Edith Weisskopf). Then in 1927 he published Die Krise der Psychologie (The Crisis of Psychology). In the book, Bühler argued that the problem of explaining the social significance of language showed that psychology has lost the complexity and richness required to synthesize three levels of psychology: experience, behavior and intellectual structure (Bühler 1927, Hacohen 2000 and Humphrey 1951). A framework was needed for unifying the different narrow ‘schools’ of psychology: Behaviorism, Gestalt theory, psychoanalysis, associationism, and humanistic psychology. They were deficient in their narrow domain of application. The unity of psychology demanded methodological pluralism at the point of cooperation.
