Otto Selz

Otto Selz was a German psychologist, born in Munich, Bavaria. He formulated the first non-associationist theory of thinking, in 1913. Influenced by the German phenomenological tradition, Selz used the method of introspection, but unlike his predecessors, his theory developed without the use of images and associations. Wilhelm Wundt used the method of introspection in the 1880s, but thought that higher-level mental processes could not be studied in the scientific laboratory.
