Magnitude and category scaling methods were employed by journeymen electronics personnel to scale the apparent complexity of various aspects of their own job. The resultant data indicated that essentially equivalent scales were produced across the methods and that the continua of perceived complexity of 4 “activity” stimuli and of 16 “circuit” stimuli were metathetic. Since the distortions as the result of the introduction of different scaling methods were minimal, the present data suggested support for a single psychophysical law in the avionics job performance area.
