Interference Among Sources of Information in Complex Integrated Displays.
Somers,Patricia, Robert G. Pachella · Defense Technical Information Center (DTIC) · 1977
The successful representation of complex information in a multidimensional display depends on the knowledge and exploitation of naturally occurring interdimensional relationships. Sets of dimensions vary in separability, the extent to which the perception of each dimension is independent of co-occurring dimensions. Nonseparability due to integrality among dimensions is distinguished from nonseparability due to masking and distraction. Integrality may result from two separate types of dimensional relationships, combination and interaction. Combination can be isolated from interaction using filtering tasks with no speed stress. A method for measuring combination by requiring filtering in a similarity judgment task is developed and a demonstration experiment is presented. (Author)
