The answer is that "they were not pragmatic".
Most analysts trust that Structuralism, the psychology of E. B. Titchener, was a devoted duplicate of Wilhelm Wundt's unique psychology. Titchener rejected a large number of Wundt's objectives and ideas, and ought to be seen as a conventional British associationist and positivist as opposed to as an adherent of Wundt. Similitudes of Wundt's framework and Titchener's framework to current mental reasoning are noted.
