工作记忆中的视觉信息和言语信息都引导视觉注意转向与记忆匹配的对象。我们测试了：(a)视觉和言语表征对注意力部署的影响是否不同；并且(b)两种类型的表示可以以自上而下的方式平等地使用。我们要求参与者在每次试验开始时保持一个视觉线索或一个口头线索，并以一个记忆任务结束，以确保每个线索在工作记忆中都是积极的。在记忆任务之前，出现了一个视觉搜索任务，其中效度被操纵为有效、中性或无效。我们还操纵了有效试验的概率（20%，50%和80%），这些试验在任务之前已经被告知给参与者。与早期的研究结果一致，视觉表征的注意力引导受到概率的调节。我们还发现，这对口头表征也是正确的，而且这些影响在表征类型之间没有差异。这些结果表明，工作记忆中的视觉表征和言语表征都可以策略性地控制注意力引导。
Both visual and verbal information in working memory guide visual attention toward a memory‐matching object. We tested whether: (a) visual and verbal representations have different effects on the deployment of attention; and (b) both types of representations can be used equally in a top‐down manner. We asked participants to maintain a visual cue or a verbal cue at the beginning of each trial, and ended with a memory task to ensure that each cue was represented actively in working memory. Before the memory task, a visual search task appeared where validity was manipulated as valid, neutral, or invalid. We also manipulated the probability of valid trials (20%, 50%, and 80%), which had been told to the participants prior to the task. Consistent with earlier findings, attentional guidance by visual representations was modulated by the probability. We also found that this was true for verbal representations, and that these effects did not differ between representation types. These results suggest that both visual and verbal representations in working memory can be used strategically to control attentional guidance.
