ABSTRACT
In making use of recent computer technology, a study was conducted to examine the mental models of industrial jobs. Cognitive differences in the mental models of engineers, healthcare professionals, and trades persons pertaining to industrial job tasks were examined. Elements consisting of video presentations of task examples and the sorting manipulation of the examples were combined for a clear and consistent interface that allowed ease of use with minimum practice. Subjects used the system to categorize and sort twenty-five different video clips of industrial job tasks into file folder icons. A cluster analysis was used to examine differences in the categorization and sorting patterns of subjects. Results established differences in the mental models of engineers, healthcare professionals, and trades persons pertaining to industrial job tasks. The results are discussed in terms of their theoretical and methodological significance; their practical significance as a means of educating individuals involved with maintaining industrial and ergonomic factors; and further uses of this computer program in research.
