Toward a Synthetic Physiological Psychology

Abstract

The word “synthetic” in the title of this paper has three meanings, each of which highlights a fundamental problem with physiological psychology, and. at the same time, offers a solution. (1) Synthetic means artificial—made by man, not by nature. To separate physiological psychology from medicine, and to build a science of pure function in humans (which is what psychology is), apart from a science of the mechanics of living human tissue (which is what medicine is), synthetic physiological psychology adopts a physically achieved analytic approach to the design, not of people, but of robots that behave like people. This avoids the misuse of reductionism. (2) Analysis by itself is not adequate; every analysis must be validated immediately by synthesis. Some forms of physically achieved analysis and resynthesis, particularly appropriate for synthetic physiological psychology, are contrasted with the hypothetico-deductive method, as a complementary scientific method of arriving at simple facts about complex living systems. (3) Synthetic also means integrative—at present, the various subfields of psychology are not united by principles based on the action of common units of function, derived by a physically achieved analysis. A simple procedure is described that can provide them.
