Task Representation for Decision Support, Performance Enhancement and Training
Find this in a Library
We use the term cognitive task analysis (CTA) to refer to the cognitive aspects of any task (including primarily physical tasks and tasks conducted in teams), and distinguish two linked phases: 1) elicitation and 2) representation. This paper addresses the representation of cognitive task content, for its critical role in bridging CTA with cognitive engineering. An ongoing task analysis of jet fighter crewmembers on air defense supression (Wild Weasel) missions provides an opportunity to comment critically on the utility of the Plan-Goal Graph representation (Sewell & Geddes, 1990) we have been using.
