As one of the interruption management strategies, using information cues can effectively mitigate the sequential task performance decline caused by task interruptions. However, how to use information cues to optimize post-interruption performance in a concurrent multitasking environment is still unknown. This study analyzed the effects of retrieval cue (a cue that points towards the last action before interruption) and assistant cue (a cue that points towards the next action after interruption) on interrupted task performance in the concurrent multitasking environment through two experiments. The effects of cues on different levels of personnel fatigue were further investigated using electroencephalography (EEG). The results show that assistant cues effectively improve concurrent multitasking interruptions, with a more significant impact observed in the presence of fatigue. Retrieval cues do not enhance the performance of interrupted tasks but can reduce the operator workload and improve alertness. The findings provide valuable insights for managing interruptions in concurrent multitasking environments.
作为中断管理策略之一，使用信息提示可以有效减轻任务中断导致的顺序任务绩效下降。然而，在并发多任务环境中如何使用信息提示来优化中断后的绩效仍然未知。本研究通过两个实验分析了检索提示（指向中断前最后一个动作的提示）和辅助提示（指向中断后下一个动作的提示）对并发多任务环境中中断任务绩效的影响。使用脑电图（EEG）进一步研究了提示对不同程度人员疲劳的影响。结果表明，辅助提示有效地改善了并发多任务中断，在存在疲劳的情况下影响更为显著。检索提示不会提高中断任务的绩效，但可以减轻操作员的工作量并提高警觉性。这些发现为管理并发多任务环境中的中断提供了有价值 的见解。
