This paper describes three cognitive principles of display design proposed within the framework of the multiple resources model of human performance. These principles are stimulus-central processing compatibility describing the optimum association of display format print, speech, graphics, sound, and lateral visual field to the working memory code Spatial-verbal used in performance of a task resource competition, describing how the optimum configuration for displaying two or more sources of task information is to employ separate resources and task integration, a principle that constrains the application of the resource competition when separate stimulus elements must be integrated int a single mental model for the task. Five experiments are described that investigate these principles in isolation and in different combinations in aviation-related tasks. The data generally support all three principles, and indicate that compatibility is a dominant concept when placed in opposition with resource competition.
