Abstract

Identifying contacts in a military context can require operators to integrate multiple cues and to adjust response criteria to event base rates. The current experiment tested whether support from a decision aid would improve these processes. Participants performed a signal identification task that required them to integrate cues displayed as visual scale readings. In a static condition, participants saw a single set of readings each trial. In dynamic conditions, readings were updated over time. Base rates of signal categories were unequal, requiring participants to adopt biased response criteria to maximise response accuracy. Participants worked with or without an aid that combined cues and base rate information in an ideal manner. Support from the aid pushed participants' response criteria towards optimal and improved integration of dynamic cues. Decision aids may be especially useful when task demands require biased response criteria and when cues are sampled over time.

决策支持改进了多线索信号识别任务中的信息整合和标准定位。
在军事环境中识别接触者需要操作员整合多种线索,并根据事件基础率调整响应标准。本实验测试了决策辅助工具的支持是否会改善这些过程。参与者进行了一项信号识别任务,要求他们整合以视觉刻度读数显示的线索。在静态条件下,参与者每次试验只看到一组读数。在动态条件下,读数会随时间更新。信号类别的基准率是不相等的,这就要求参与者采用有偏差的反应标准,以最大限度地提高反应的准确性。参与者可以在有辅助工具或没有辅助工具的情况下工作,辅助工具以理想的方式将提示信息和基准速率信息结合在一起。辅助工具的支持将参与者的反应标准推向最佳,并改善了动态线索的整合。当任务需求要求采用有偏差的反应标准,并且线索是随时间采样时,决策辅助工具可能会特别有用。

期刊介绍: Ergonomics, also known as human factors, is the scientific discipline that seeks to understand and improve human interactions with products, equipment, environments and systems. Drawing upon human biology, psychology, engineering and design, Ergonomics aims to develop and apply knowledge and techniques to optimise system performance, whilst protecting the health, safety and well-being of individuals involved. The attention of ergonomics extends across work, leisure and other aspects of our daily lives. The journal Ergonomics is an international refereed publication, with a 60 year tradition of disseminating high quality research. Original submissions, both theoretical and applied, are invited from across the subject, including physical, cognitive, organisational and environmental ergonomics. Papers reporting the findings of research from cognate disciplines are also welcome, where these contribute to understanding equipment, tasks, jobs, systems and environments and the corresponding needs, abilities and limitations of people. All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymous refereeing by independent expert referees.
