ABSTRACT
This chapter focuses on two collaborative studies carried out by G. E. Muller, one with his research assistant, Friedrich Schumann, and one with an American graduate student, Lillien J. Martin. In the course of his research on the history of memory experimentation, Edward Haupt came across Muller’s research on psychophysics. In a word, classical psychophysics, that had indubitably originated with G. T. Fechner, were probably propagated internationally as much through Muller’s writings on psychophysics as through Fechner’s. E. B. Titchener wrote that “there can be no doubt that the work of Martin and Muller will stand as a landmark in the history of experimental psychology”. It implies that the psychophysicists at Gottingen, under Muller’s leadership, were amplifying their readiness to expand the discussion from constant errors to conscious psychological processes. The pioneering research of several of the doctoral students working with Muller, however, focused on the study of psychological processes in themselves.
