众所周知，视觉工作记忆(VWM)的表现受编码过程中呈现的注意线索的调节。有趣的是，在编码之后、但在测试阶段之前提供的回溯提示也会提高性能。这种性能上的改进被称为追溯提示好处。我们调查了回溯线索的益处是否对线索类型敏感，参与者是否意识到回溯线索对他们成绩的改善，以及这种影响是否处于战略控制之下。实验一比较了依赖于自下而上注意的突然出现的回溯线索、依赖于自上而下注意的数量回溯线索以及依赖于两者的混合的箭头回溯线索的潜在线索优势。我们发现只有箭头追溯线索才有显著的追溯线索效应。在实验2中，我们测试了参与者对信息性追溯线索使用的意识，发现他们意识到自己的成绩有所提高。在实验3中，我们考察了被试是否对回溯线索进行了策略控制。这种复古暗示很难被忽视，这表明战略控制力很低。回溯效应似乎在有意识的意识之内，但不在完全的战略控制之下。
It is well known that visual working memory (VWM) performance is modulated by attentional cues presented during encoding. Interestingly, retrospective cues presented after encoding, but prior to the test phase also improve performance. This improvement in performance is termed the retro-cue benefit. We investigated whether the retro-cue benefit is sensitive to cue type, whether participants were aware of their improvement in performance due to the retro-cue, and whether the effect was under strategic control. Experiment 1 compared the potential cueing benefits of abrupt onset retro-cues relying on bottom-up attention, number retro-cues relying on top-down attention, and arrow retro-cues, relying on a mixture of both. We found a significant retro-cue effect only for arrow retro-cues. In Experiment 2, we tested participants’ awareness of their use of the informative retro-cue and found that they were aware of their improved performance. In Experiment 3, we asked whether participants have strategic control over the retro-cue. The retro-cue was difficult to ignore, suggesting that strategic control is low. The retro-cue effect appears to be within conscious awareness but not under full strategic control.
