Abstract

Resource allocation under risk and uncertainty is a complex problem, specifically when making course of action planning decisions on the battlefield. Previous research in this domain has demonstrated the performance impact of visualization aids, feedback, practice, information frame, and time pressure. However, the focus of prior research has been on how to help operators determine where to optimally place a single asset. The current research addressed the same domain, but with the multi-attribute decision of how to best allocate a suite of robotic assets across the battlefield. We explored the impact of information frame and time pressure on decision performance and situation awareness, but further manipulated whether the information frame of decision criteria were forced to a single consistent frame or allowed to vary according to which term was intuitive, regardless of frame. We found both faster response times and more accurate responses within consistently-framed displays over mixed-frame displays. In addition, response time varied less in the consistently-framed displays than the mixed-frame displays.
