The basis for Wundt’s initial discussion of the problem of introspection is provided by his insistence on the distinction between “self-observation” … - Kurt Danziger

The term “introspective psychology” is misleading in that it covers a variety of diverging positions on the theory and practice of introspection. From the beginning there was a basic discrepancy between the British and the German philosophic tradition, the former relying more exclusively on introspection than the latter. Wilhelm Wundt’s advocacy and use of introspection was extremely circumscribed and essentially limited to simple judgments tied to external stimulation. During the first decade of the twentieth century some experimental psychologists, notably E. B. Titchener and the , greatly enlarged the scope of introspection, ushering in the brief vogue of “systematic introspection.” The latter never gained wide support in North America and was supplanted in Germany by developments that do not constitute “introspective psychology” in any precise sense.

For such fields deep historical studies can have considerable contemporary relevance and hence fall within the boundaries of the field itself. Weber and Durkheim are still studied by sociologists, just as Adam Smith and Ricardo are still studied by economists, whereas Galilean and Newtonian studies are not part of physics but of an altogether different discipline, the history of science.

The great majority of experimental psychologists relate to the tradition of their field in much the same way as physicists. Their look at the past might take the form of a review of the literature in a specific research area, and perhaps they would go so far as to take time off for celebrating a few icons on appropriate ceremonial occasions, but there is no room in their world for a reflective or critical history. They would gladly leave anything like that to the professional historians without any sense of having surrendered something that might have the slightest relevance to their own research interests. In the U.S. this attitude may be more widespread than elsewhere, and it is certainly accompanied by a growing tendency for the history of psychology to be taken up by historians rather than psychologists, but of course, the same attitudes are to be found wherever there are psychological laboratories.
