Task structure and strategy variation in componential task analysis.

[摘要] Technological advancement has changed the nature of interactions withinmodern man-machine systems, with workload becoming more a load on themental capacities of the human systems component than on his/her physicalcapabilities. Moreover increased system capabilities may havedisproportionately reduced the time available to perform these mentaloperations, thereby adding new and more complex cognitive tasks. A conceptcrucial to the evaluation of modern man-machine systems is that of theresulting implications of loading and overloading the cognitivecapabilities of the human systems component, namely the measurement ofmental workload.
