Book excerpt: In a laboratory study of information assimilation under simulated command information processing system procedures, 30 subjects were required to extract specific items of information from a series of slide projected displays. Speed (search time) and accuracy of information assimilation were analyzed to determine whether they were affected by amount of information (number of lines in a slide), density (ratio of letter height to space between lines), position of pertinent information on the slide, and complexity (number of columns to be searched). While accuracy was high under all conditions of search, there were significant increases in search time as a function of changes in display characteristics--increase from 10 to 25 lines of information, pertinent information placed near bottom of the slide, increase in number of columns to be searched. However, search time for high density of information was slightly shorter than for medium and low densities. (Author).
