An Introduction to Nonparticipant Observational Research Techniques

At least since the time of Darwin, scientists have been using systematic observational techniques in the conduct of research. During the 1920s and 1930s, in psychology and zoology there was widespread use of the systematic recording of quantitative analysis of observed behavioral data. In both professions, this enthusiasm gradually gave way to an emphasis on controlled experiments. In psychology, the incidence of nonparticipant observational research dwindled to almost zero. In zoology, it became somewhat attenuated, but was preserved as a part of the ethological tradition (Hutt and Hutt, 1970).
