Abstract : The study is concerned with the effects of alpha-numeric and graphic presentation of information on the accuracy and timeliness of decision making and confidence in the decision made. These variables were examined in the context of a simulated constantly changing battlefield situation. A series of slides depicting battlefield information were presented both alpha-numerically and graphically to subjects. Each subject was asked to make a decision as to the enemy forces activity and to express his confidence in his decision in terms of probability odds. Also, for each mode of display, the sequence of information was presented at two different rates of updating -- 7 vs 14 updated slides. No differences were found between alpha-numeric and graphic presentation in terms of quality or timeliness of decision or in confidence score; nor were they found in results with the two rates of updating. Greater shifts in level of confidence were shown, for both modes of presentation, from slide to slide in the 7-slide updating than in the 14-slide updating. Results also showed that, on the average, subjects whose final decision was correct had made the correct response three-fourths of the way to their final decision. (Author)
