Certitude Judgments and Accuracy of Information Assimilation from Visual Displays

摘要

The study was conducted to determine the extent to which certitude coincides with the accuracy of information assimilation. Divergence would indicate the importance of separate consideration of certitude in relation to information presentation variables. The study was also designed to reveal something of the nature of the certitude-accuracy relationship, and to provide insight into the possible implications of certitude for command decision making. More specifically, the study was concerned with the degree to which accuracy of information assimilation from displays and self-judgments of certitude of the accuracy of the assimilation were similarly affected by variations in (1) the amount of information presented in a slide, (2) the number of symbols removed from a slide, and (3) varying combinations of amount and symbols removed. A prelude to the analysis was the evaluation of an eight-point interval scale as a vehicle for obtaining certitude judgments. (Author)
