Impact of Numerical and Graphical Formats on Dynamic Decision Making Performance: An Eye-Tracking Study

Abstract

This paper presents a study in which we manipulated theinterface of a computer simulation into: graphical andnumerical formats. We obtained both performance andeye-tracking learning curves from individuals assigned toone of these two conditions. Our findings indicate thatalthough performance is not different between the twointerfaces, the amount of attention as measured by thenumber of eye-tracking points was very different in thegraphical and numerical conditions. Attention increasedover time in the numerical condition, but was stable in thegraphical condition. These results showed that thestrategies used to make decisions in dynamic environmentsvary according to the form of information presentation.
