The validity of the display evaluative index technique was investigated in two separate studies. Both studies indicated adequate predictive validity for the technique. The ability of the technique to predict decision making was found to be superior to its ability to predict information extraction processes. Generally, it was found that pictorial type displays are superior to tabular displays for decision making no difference seemed manifest between the two display types for information extraction. Adding appropriate color coding seemed to augment the ability of the user to employ display information. As fact density increased, display decision making scores decreased.
