最近的研究表明，即使在刺激阵列消失几秒钟后，提示最有可能随后探测的项目，也可以增强记忆表现。尽管这种回溯性线索引起了相当大的兴趣，但其背后的机制尚不清楚。在这里，我们测试了一个假设，即复古线索可能会保护一个项目免受时间的退化。我们采用了两种以前没有在回溯任务中部署过的技术。首先，我们使用了一个敏感的、连续的量表来报告记忆项目的方向，而不是在以前的研究中通常使用的二元测量（改变或不改变）。其次，为了研究记忆随时间的稳定性，我们还系统地改变了回溯提示和报告之间的持续时间。尽管报告未提示物体的准确性在短时间内迅速下降，但回溯提示项目的准确性明显更稳定，在时间和防止遗忘方面的准确性下降可以忽略不计。物体颜色的回溯线索和空间回溯线索一样有利。这些发现表明，在记忆维持过程中，即使在不再可见的情况下，也可以有选择地重新部署注意力资源，以保护随着时间的推移回忆起提示项目的准确性，但同时也要付出相应的回忆未提示项目的代价。
Recent studies have demonstrated that memory performance can be enhanced by a cue which indicates the item most likely to be subsequently probed, even when that cue is delivered seconds after a stimulus array is extinguished. Although such retro-cuing has attracted considerable interest, the mechanisms underlying it remain unclear. Here, we tested the hypothesis that retro-cues might protect an item from degradation over time. We employed two techniques that previously have not been deployed in retro-cuing tasks. First, we used a sensitive, continuous scale for reporting the orientation of a memorized item, rather than binary measures (change or no change) typically used in previous studies. Second, to investigate the stability of memory across time, we also systematically varied the duration between the retro-cue and report. Although accuracy of reporting uncued objects rapidly declined over short intervals, retro-cued items were significantly more stable, showing negligible decline in accuracy across time and protection from forgetting. Retro-cuing an object’s color was just as advantageous as spatial retro-cues. These findings demonstrate that during maintenance, even when items are no longer visible, attention resources can be selectively redeployed to protect the accuracy with which a cued item can be recalled over time, but with a corresponding cost in recall for uncued items.
