Abstract : Improved technology and automation are being advocated as the solution to problems of lagging productivity and human error. However, the very technology that is sought to improve productivity and reduce human crewmember's workload often has the opposite effect. An alternative is human-centered automation that aids and supports the human crewmember. To design it requires an expanded view of workload as a strategic task management problem, contrasted with the more traditional view of workload as competition for a limited pool of processing resources at any one time. We introduce a theoretical framework for understanding human cognitive processing that builds on active theories of perception, connectionist theories of associative knowledge structures, and schema theories of comprehension. The framework addresses mechanisms of attention, situation awareness, and real-time management of multiple streams of activity.
