Previous research has revealed that we create and maintain mental representations for perceived objects on the basis of their spatiotemporal continuity. An important question is what type of information can be maintained within these so-called object files. We provide evidence that object files retain specific attentional control settings for items presented inside the object, even when it disappears from vision. The objects were entire visual search displays consisting of multiple items moving into and out of view. It was demonstrated that search was speeded when the search target position was repeated from trial to trial, but especially so when spatiotemporal continuity suggested that the entire display was the same object. We conclude that complete spatial attentional biases can be stored in an object file.
先前的研究表明，我们基于感知对象的时空连续性来创建并维持对它们的心理表征。一个重要的问题是，在这些所谓的对象文件中可以保留何种类型的信息。我们提供的证据表明，即使对象从视野中消失，对象文件仍会为对象内部呈现的项目保留特定的注意力控制设置。这些对象是由多个进出视野的项目组成的完整视觉搜索显示。结果表明，当搜索目标位置在试验中重复出现时，搜索速度会加快，但当时空连续性表明整个显示是同一个对象时，搜索速度加快得尤为明显。我们得出结论，完整的空间注意力偏差可以存储在对象文件中。
