The study was designed to examine whether the availability of reduced-processing decision support system interfaces could improve the decision making of inexperienced personnel in the context of
Although research into reduced-processing decision support systems has demonstrated benefits in minimizing cognitive load, these benefits have not typically translated into direct improvements in decision accuracy because of the tendency for inexperienced personnel to focus on less-critical information. The authors investigated whether reduced-processing interfaces that direct users' attention toward the most critical cues for decision making can produce improvements in decision-making performance.
Novice participants made incident command-related decisions in experimental conditions that differed according to the amount of information that was available within the interface, the level of control that they could exert over the presentation of information, and whether they had received decision training.
The results revealed that despite receiving training, participants improved in decision accuracy only when they were provided with an interface that restricted information access to the most critical cues.
It was concluded that an interface that restricts information access to only the most critical cues in the scenario can facilitate improvements in decision performance.
Decision support system interfaces that encourage the processing of the most critical cues have the potential to improve the accuracy and timeliness of decisions made by inexperienced personnel.
本研究旨在考察在何种情况下，简化处理决策支持系统界面的可用性是否能够提高缺乏经验的人员的决策能力。
尽管研究表明简化处理决策支持系统在最小化认知负荷方面具有优势，但由于缺乏经验的人员倾向于关注不太重要的信息，这些优势通常并未转化为决策准确性的直接提高。作者研究了是否可以通过引导用户关注决策的最关键线索的简化处理界面来提高决策绩效。
新手参与者在实验条件下做出与事件指挥相关的决策，这些条件根据界面内可用信息量、他们可以控制信息呈现的程度以及是否接受过决策培训而有所不同。
结果表明，尽管接受了培训，但只有当参与者获得限制信息访问最关键线索的界面时，他们的决策准确性才会提高。
结论是，限制场景中仅访问最关键线索的信息访问的界面可以促进决策绩效的提高。
鼓励处理最关键线索的决策支持系统界面有可能提高缺乏经验的人员的决策准确性和及时性。
