是否有一个意图产生的性能成本正在进行的活动（任务干扰）是核心的理论主张，有关机制的线索检测基于事件的前瞻性记忆。最近的证据表明，任务干扰主要反映了注意分配政策存储在内存中时，意图编码。本研究探讨了这些政策是否可以改变正在进行的任务经验。在实验1中，任务干扰更大大减少时，预期的线索没有比当他们。实验2复制了这种效果时，前瞻记忆任务的重要性被强调。在实验3中，任务干扰随着时间的推移而减少，这种减少是更大的预期线索时，没有比当他们。提示呈现对于维持任务指令建立的注意分配策略至关重要。这是第一篇文章，以证明正在进行的任务经验的任务干扰的变化，而不预先警告个人的相关性，即将到来的正在进行的任务试验的意图。
Whether having an intention produces a performance cost to ongoing activities (task interference) is central to theoretical claims regarding the mechanisms underlying cue detection in event-based prospective memory. Recent evidence suggests that task interference primarily reflects an attention allocation policy stored in memory when intentions are encoded. The present study examined whether these policies can change with ongoing task experience. In Experiment 1, task interference was more greatly reduced when expected cues were not presented than when they were. Experiment 2 replicated this effect when the importance of the prospective memory task was emphasized. In Experiment 3, task interference decreased with time, and this decrease was greater when expected cues were not presented than when they were. Cue presentation is crucial to maintenance of attention allocation policies established by task instructions. This is the first article to demonstrate changes in task interference with ongoing task experience without forewarning individuals of the relevance of upcoming ongoing task trials to intentions.
