Abstract

Multimodal warnings elicit faster response times than unisensory warnings in cockpits. However, how visual and auditory task demands affect the detection of multimodal warnings remains unclear. This study recruited 30 pilots and 30 control participants to complete a warning response task and an aviation visual or auditory task. The race model inequality analysis indicated that the multisensory enhancement effect decreased as the load increased. The analysis of variance indicated an interaction effect among modality, load level, and task type on response times. Results suggested that demanding tasks may affect the detection of multimodal warnings more substantially than that of unisensory warnings within the same modality. The slowing of response times to multimodal warnings may be driven by the more load-sensitive sensory component. The findings were consistent across groups. This study provides practical implications for multimodal warning design and theoretical insights into multimodal processing.

视觉和听觉任务负荷如何不同地损害多模态警告的优势。

在驾驶舱内，多模式警告比单感官警告的反应时间更快。然而，视觉和听觉任务需求如何影响多模态警告的检测尚不清楚。本研究招募了30名飞行员和30名对照参与者来完成一个警告反应任务和一个航空视觉或听觉任务。种族模型不平等分析表明，多感官增强效应随着负荷的增加而降低。方差分析表明，模式、负荷水平和任务类型对反应时间有交互作用。结果表明，高要求任务可能比同一模态下的单感觉警告更显著地影响多模态警告的检测。对多模态警告的响应时间变慢可能是由负载敏感的感官成分驱动的。这些发现在不同的群体中是一致的。本研究为多模态预警设计提供了实践意义，并为多模态处理提供了理论见解。

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.
