ABSTRACT
Psychology and engineering owe much more to each other than is generally recognized for the two disciplines are linked in many ways: by the men who have moved from engineering to psychology, by the engineering technology that makes possible most psychological research, by the problems that each field presents to the other, and by the ideas from one that enrich the other. This essay begins with a characterization of the engineering profession and follows with a discussion of some contributions of engineering to psychology. The next section reverses orientation to look at some contributions from psychology to engineering. In the final section, I speculate about future relations between psychology and engineering.
