The birth of experimental psychology in Germany between psychophysical methods and physiological theories.
In 1879 Wundt's laboratory of psychology was opened in Leipzig, and it has been the landmark ever since for the beginning of modern experimental psychology. Its founder, Wilhelm Maximilian Wundt, was the first to successfully demarcate the areas of scientific psychology as being distinct from either physiology or philosophy, thus guaranteeing the survival of psychology, which was regarded as an autonomous discipline set upon a secure institutional framework. This paper attempts to clarify the basic facts and concepts related to the roots of scientific psychology in Germany, i.e., the context in which the "Founding Father" worked, as well as of those predecessors who proposed the topics and apparatus of his laboratory. Attention will be paid in particular to the psychophysical methods of Weber and Fechner, especially in regard to colour perception. In this context, an outline is presented of the history of reaction time experiments in astronomy, physiology, and psychology, and of the role played by the scientific instruments. It is shown how the methodology of physics and physiology contributed to the emancipation of scientific psychology and to the formation of its orientation.
