Underload and overload in working life: outline of a multidisciplinary approach.

A research project is outlined in which concepts and methods from social psychology and psychophysiology are integrated in the study of human adaptation to underload and overload related to technically advanced work processes. Attempts are made to identify aversive factors in the work process by studying acute stress reactions, e.g., catecholamine excretion, in the course of work and relating these to long term, negative effects on well-being, job satisfaction and health. Data from a pilot study of sawmill workers support the view that machine-paced work characterized by a short work cycle and lack of control over the work process constitutes a threat to health and well being.
