Abstract:

Multiple Resource Theory proposes that multi-variable displays will be better processed when information is presented in several different display formats i.e., verbal, spatial, visual, auditory. We argue here that this superiority of separate formats does not hold if the displayed elements are correlated or must be integrated into a single mental model. We report two experiments that confirm this hypothesis In experiment 1, subjects monitor two numerical displays. If the Task calls for separate independent decisions concerning the value of each display, performance is best when one is spatial analog and the other verbal. If the task calls for integration of both displays into a common decision rule, performance is best when homogeneous display formats are used. In experiment 2 subjects monitor the display of several dynamic elements that compose a dynamic system. Performance is found to be better if these correlated elements are integrated into a configural object display, than if they are displayed as separate bargraphs.
