Karl BühlerDied 24 Oct 1963 at age 84 (born 27 May 1879).German psychiatrist and psychologist who was known chiefly for his studies of the thought process. While a professor at the University of Vienna (1922-38), his views were influenced by the thinking of Trubetzkoy and other members of the Prague School. His Sprachtheorie (1934) presented a sign theory with particular emphasis on the functions of language, and a distinction between two "fields" which form the context in which a sign is used. The "symbolic field" (Symbolfeld) is formed by the other signs that make up an utterance; the "deictic field" (Zeigfeld) is formed by the context in which it is uttered and is the origin of modern conceptions of deixis. Bühler emigrated to the USA in 1939, practising as a clinical psychologist from 1945. |
