Book Description
A series of studies was conducted by the COMMAND SYSTEMS Task in which a variety of display variables are systematically investigated in terms of their effects on information assimilation and decision making in a command and control setting. The present study explores the effects of type and number of updating change, amount of information presented, and selected enhancement techniques on confidence and on the relationship of confidence to accuracy of information assimilation. Findings indicate: (1) The more effective the enhancement technique, the higher the certitude-accuracy relationship. With the best enhancement technique (double-cue coding), 64 percent of the certitude variance could be accounted for by accuracy variance; with the poorest (hard copy), only 20 percent. (2) Both over-certitude and under-certitude was evidenced, with over-certitude tending to increase with the less effective enhancement techniques. (3) Increase in either amount of information presented or amount of updating resulted in decline in both mean accuracy and mean certitude, the rate varying widely over the different enhancement techniques and over types of update. (4) Although effects of the main variables on accuracy and certitude were highly similar, the correspondence did not hold for individual performance scores. Findings suggest need to improve agreement between a man's performance in information assimilation and his judgment of that performance. To more adequately determine the nature of the effects of enhancement, certitude should be measured in the same quantitative metric (percent) as accuracy. (Author).
