In safety-critical domains, frequently intentions need to be delayed until an ongoing task is completed. Research using the delay-execute paradigm showed that interruptions during the delay cause forgetting. However, staff members often handle an initial distraction not by interrupting the ongoing task but by acknowledging the distraction or multitasking. In Experiments 1a and 1b, we observed that, compared to a no distraction condition, multitasking significantly decreased remembering of intentions and interrupting decreased remembering even further. In Experiment 2, interruptions with context change reduced remembering of intentions compared to uninterrupted delays, and at the same time, interruptions without context change improved memory performance compared to uninterrupted delays. However, improved memory performance resulted in decreased interrupting task performance. Theoretically, the results support the contextual cueing mechanism of delay-execute tasks. Considering safety-critical domains, multitasking, interruptions and context changes can contribute to forgetting of tasks.
在安全关键领域，意图常常需要延迟，直到正在进行的任务完成。使用延迟执行范式的研究表明，延迟期间的中断会导致遗忘。然而，工作人员通常不是通过中断正在进行的任务来处理最初的干扰，而是通过承认干扰或进行多任务处理。在实验1a和1b中，我们观察到，与无干扰条件相比，多任务显著降低了对意图的记忆，而中断则使记忆进一步下降。在实验2中，与未中断的延迟相比，伴有情境变化的中断降低了对意图的记忆，同时，与未中断的延迟相比，无情境变化的中断提高了记忆表现。然而，记忆表现的提高导致了中断任务表现的下降。从理论上讲，这些结果支持了延迟执行任务的情境线索机制。考虑到安全关键领域，多任务、中断和情境变化可能会导致任务遗忘。
