Abstract

Situation awareness (SA) and workload have both received considerable attention over the past several decades. Little research has investigated the relationship between these two constructs however. The present study examines the relationship between workload and SA in a task involving operation of unmanned vehicles performing an inspection task. Overall, an inverse correlation between SA and workload was found, with SA decreasing by approximately 20% as workload increased. Unexpectedly, considerable differences in this relationship across individuals were found, however, with 50% of participants showing a correlation between SA and only one workload measure (subjective or secondary task) and 30% showing no correlation between SA and workload on either measure. Reasons for dissociation within different measures of workload and SA are discussed, as well as potential reasons for individual differences leading to dissociations across these two constructs.

情境意识和工作量的差异。

在过去的几十年里，情境意识（SA）和工作量都受到了相当大的关注。然而，很少有研究对这两个概念之间的关系进行调查。本研究探讨了在无人驾驶车辆执行检查任务时，工作量与 SA 之间的关系。总体而言，研究发现 SA 与工作量之间存在反相关关系，随着工作量的增加，SA 下降约 20%。然而，意想不到的是，这种关系在不同个体之间存在很大差异，50% 的参与者只显示出 SA 与一种工作量测量（主观或次要任务）之间存在相关性，30% 的参与者显示出 SA 与任何一种测量的工作量之间都不存在相关性。本文讨论了在不同的工作量测量和 SA 测量中出现分离的原因，以及个体差异导致这两个结构之间出现分离的潜在原因。

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.
