The current study shows that spatial visual attention is used to retrieve information from visual working memory. Participants had to keep four colored circles in visual working memory. While keeping this information in memory we asked whether one of the colors was present in the array. While retrieving this information, on some trials a probe dot was presented. When this probe dot was presented at the location of the color that had to be retrieved, participants responded faster than when it was presented at another location. Our findings further elaborate the role of visual attention in working memory: not only is attention the mechanism by which information is stored into working memory, it is also the mechanism by which information is retrieved from visual working memory.
当前的研究表明，空间视觉注意力被用于从视觉工作记忆中检索信息。参与者必须在视觉工作记忆中记住四个彩色圆圈。在将这些信息保留在记忆中的同时，我们询问阵列中是否存在其中一种颜色。在检索此信息时，在一些试验中会呈现一个探测点。当这个探测点出现在必须检索的颜色的位置时，参与者的反应比它出现在另一个位置时更快。我们的研究结果进一步阐述了视觉注意力在工作记忆中的作用：注意力不仅是信息存储到工作记忆中的机制，也是从视觉工作记忆中检索信息的机制。
