摘要

工作环境中的中断会给操作人员带来额外的脑力劳动负担，这一现象已引起了大量研究的关注。本研究基于人类信息处理的感知和认知视角，采用 2（感知主要任务和认知主要任务）*2（感知中断任务和认知中断任务）因子设计，设计了四种中断条件。采用多模态测量方法来评估不同中断条件下的心理工作量。结果表明，当主要任务和中断任务的负荷类型不同时，它们产生的脑力劳动负荷要高于相同负荷类型。这可能是由于感知任务和认知任务会增加切换时的心理工作量。此外，基于多模态指数数据，建立了中断恢复延迟时间的预测模型和中断条件的分类模型，为合理安排工作和防止精神超负荷提供了依据。

The effects of different interruption conditions on mental workload: an experimental study based on multimodal measurements.

Interruptions in the working environment cause extra mental workload for the operators, and this phenomenon has garnered significant research attention. This study designed four interruption conditions based on the perceptual and cognitive perspectives of human information processing, using a 2(perceptual primary task and cognitive primary task)*2(perceptual interruption task and cognitive interruption task) factorial design. Multimodal measurement methods were used to evaluate mental workload in different interruption conditions. The results show that when the primary task and the interruption task are different load types, they generate a higher mental workload than the same load type. It can be attributed to the fact that perceptual tasks and cognitive tasks increase mental workload during switching. In addition, based on the multimodal index data, the prediction model of interruption recovery delay time and the classification model of interruption conditions are established, which provides a basis for rational scheduling of work and preventing mental overload.

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.
