Psychophysiological Analysis of Design Work: Ergonomic Improvements Derived From Stress--Strain Research
Holger Luczak Johannes Springer Institute of Industrial Engineering and Ergonomics, Aachen University of Technology, Germany
In spite of the positive interest of ergonomists in the application of psychophysiological methods, such methods have contributed little of a positive nature to the solution of problems in ergonomics and engineering design ( Luczak, 1987; Plath & Richter, 1978). It is, however, interesting to note that the application of these methods in practical field situations delivers more useful results than laboratory research with artificial tasks. That is why the validity and reliability of a psychophysiological measurement technique may be taken as a given and its utility examined in an engineering psychophysiological context.
To demonstrate this approach, it is necessary to choose an exemplary task and a paradigm, that brings together the engineering and the psychophysiological perspectives. The task should be an information-processing or cognitive task with task components that can be supported by different technological means, one that has a high degree of representativeness for engineering. It should also be a significant task in terms of relevance to the working person. Relevance means both for the industrial application as well as for academic re-
