When observers search for an object in the environment, they compare the incoming sensory information to the attentional template, a representation of the target in visual working memory (VWM). Previous studies have shown that visual search is more efficient when the attentional template is precise. We pursued the hypothesis that the attentional template in VWM is automatically complemented by features from long-term memory, possibly to increase its precision. At the beginning of the experiment, observers learned associations between shape and color. Then, we tested whether selecting one of these shapes was influenced by the previously associated color. To this end, we ran a saccadic selection task consisting of a memory and choice display. In the memory display, the target shape was presented at central fixation and participants were instructed to foveate this shape in the subsequent choice display. In the choice display, the target shape appeared together with a distractor shape at eccentric positions. Importantly, the target shape was colorless (gray) in the memory display so that only shape, but not color was loaded into VWM. However, saccades went more frequently to the target shape when it was shown in the learned color than when this color was shown in the distractor. Thus, the color of the target shape was reinstated from episodic memory to complement the attentional template in VWM.

从情景记忆中恢复的对象特征引导注意选择。

当观察者在环境中搜索一个物体时，他们会将传入的感官信息与注意力模板进行比较，注意模板是视觉工作记忆 (VWM) 中目标的表示。先前的研究表明，当注意力模板精确时，视觉搜索更有效。我们追求这样一个假设，即 VWM 中的注意力模板会自动由来自长期记忆的特征补充，可能是为了提高其精度。在实验开始时，观察者学习了形状和颜色之间的关联。然后，我们测试了选择这些形状之一是否受到先前相关颜色的影响。为此，我们运行了一个由记忆和选择显示组成的扫视选择任务。在内存显示中，目标形状在中心注视时呈现，参与者被指示在随后的选择显示中注视该形状。在选择显示中，目标形状与偏心位置的干扰物形状一起出现。重要的是，目标形状在内存显示中是无色（灰色），因此只有形状而不是颜色被加载到 VWM 中。然而，当它以学习的颜色显示时，扫视更频繁地进入目标形状，而不是在干扰项中显示该颜色时。因此，目标形状的颜色从情景记忆中恢复，以补充 VWM 中的注意模板。目标形状在内存显示中是无色（灰色），因此只有形状而不是颜色被加载到 VWM 中。然而，当它以学习的颜色显示时，扫视更频繁地进入目标形状，而不是在干扰项中显示该颜色时。因此，目标形状的颜色从情景记忆中恢复，以补充 VWM 中的注意模板。目标形状在内存显示中是无色（灰色），因此只有形状而不是颜色被加载到 VWM 中。然而，当它以学习的颜色显示时，扫视更频繁地进入目标形状，而不是在干扰项中显示该颜色时。因此，目标形状的颜色从情景记忆中恢复，以补充 VWM 中的注意模板。
