Magnitude and category psychophysical 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 four activity stimuli an d of 16 circuit stimuli were metathetic. This latter conclusion was based on the relative homogeneity of interindividual discriminal dispersions for all the stimuli and also on the linear relation between the scales resulting from category and magnitude scaling procedures. The absence of large distortions as the result of the introduction of different methods suggested support for a single psychophysical law in the avionic job performance area. Author
