人们能够在工作记忆中优先处理更有价值的信息。目前的研究考察了这种价值效应是否是由于在维护过程中，价值较高的物品比价值较低的物品被刷新得更多。为了评估这种可能性，我们将探针值操作与引导刷新过程结合起来。展示了彩色形状阵列，在短暂的延迟之后，参与者报告了连续色轮上随机探测的形状的颜色。为了操纵探测值，在编码之前，一个项目被指示为比其他项目更有价值（即，价值更多的概念点），或者所有项目都被指示为同样有价值。为了指导刷新，在一些试验中，在维护过程中呈现两个箭头，每个箭头表示一个项目的空间位置。参与者被告知“思考”（即刷新）提示项目。如果价值提升是由注意力刷新驱动的，那么提示道具刷新应该会提高低价值或同等价值道具的性能，而不是高价值道具，因为这些道具会在没有提示的情况下刷新。这种结果的模式被观察到，为注意力刷新至少部分解释工作记忆中的探针值效应的假设提供了支持。
People are able to prioritize more valuable information in working memory. The current study examined whether this value effect is due to the items of greater value being refreshed more than lower-value items during maintenance. To assess this possibility, we combined a probe value manipulation with a guided-refreshing procedure. Arrays of colored shapes were presented, and after a brief delay, participants reported the color of one randomly probed shape on a continuous color wheel. To manipulate probe value, one item was indicated as more valuable than the rest prior to encoding (i.e., worth more notional points), or all items were indicated as equally valuable. To guide refreshing, in some trials, two arrows were presented during maintenance, each arrow cueing the spatial location of one item. Participants were told to “think of” (i.e., refresh) the cued item. If value boosts are driven by attentional refreshing, cueing an item to be refreshed should enhance performance for items that are of low or equal value, but not items of high value, as these items would be refreshed regardless of the cue. This pattern of outcomes was observed, providing support for the hypothesis that attentional refreshing at least partially accounts for probe value effects in working memory.
