Scaling the information processing demands of occupations

The purpose of this study was to provide additional validity evidence for a model of person–environment fit based on polychronicity, stimulus load, and information processing capacities. In this line of research the confluence of polychronicity and information processing (e.g., the ability of individuals to process stimuli from the environment along five dimensions of information load, interpersonal load, change load, time structure, and activity structure) is applied to the occupational environment. Using magnitude estimation scaling, college students in the United States and Portugal rated 42 occupations across five information processing demand characteristics. Results indicated that occupations could be differentiated by the information load conditions, thus producing a profile of information processing demand characteristics unique to each of the occupations tested. Additional findings provided evidence for the validity of the scaled occupational values; ratings differed reliably across Holland categories, were fairly consistent across the two cultural groups, and showed expected relationships with salary and educational level.
