本研究调查了个体如何在预期记忆任务和正在进行的任务之间分配注意力资源。因此，对前瞻性记忆任务的注意力需求的元认知期望受到操纵，而事实需求保持不变。在实验 1a 和 1b 中，我们发现，当提供有关低预期需求的信息时，事实需求较低的前瞻性记忆任务的注意力成本会显着降低，而前瞻性记忆性能基本上不受影响。在实验 2 中，在要求更高的预期记忆任务中，注意力监测也随着有关预期需求（高与低）的信息而变化，并且预期记忆性能也没有相应的变化。这些发现表明，前瞻性记忆的注意力分配策略依赖于对前瞻性记忆任务需求的元认知预期。此外，结果表明，注意力监控仅在预期任务需求反映客观任务需求的情况下对前瞻性记忆起作用。 (C) 2013 Elsevier Inc. 保留所有权利。
The present study investigates how individuals distribute their attentional resources between a prospective memory task and an ongoing task. Therefore, metacognitive expectations about the attentional demands of the prospective-memory task were manipulated while the factual demands were held constant. In Experiments 1a and 1b, we found attentional costs from a prospective-memory task with low factual demands to be significantly reduced when information about the low to-be-expected demands were provided, while prospective-memory performance remained largely unaffected. In Experiment 2, attentional monitoring in a more demanding prospective-memory task also varied with information about the to-be-expected demands (high vs. low) and again there were no equivalent changes in prospective-memory performance. These findings suggest that attention allocation strategies of prospective memory rely on metacognitive expectations about prospective-memory task demands. Furthermore, the results suggest that attentional monitoring is only functional for prospective memory to the extent to which anticipated task demands reflect objective task demands.
