当人们试图回忆说出来的信息时，他们通常会寻找世界上空白的、没有信息的地方。当信息先前与这些位置相关联时，就会出现这种空间索引行为。然而，尚不清楚这种行为是否是感知和认知系统之间简单关联的一个例子，或者位置信息是否在记忆检索中起作用。在当前的研究中，我们调查了更高层次的认知过程，如基于对象的注意力，是否参与了空间索引。参与者看到生物在屏幕周围挖洞，从地下出现，告诉他们事实。他们在两个地方看到了相同的生物，或者两个相同的生物在两个地方，这取决于挖洞动画所传达的时空线索。在回答问题时，我们发现参与者依赖于这些时空线索，关注与相关事实相关的生物之前的位置，而不是相同生物的位置。我们根据基于对象的注意机制来解释这些发现，这种机制与语义记忆和场景感知一样，并允许在动态环境中利用“外部记忆”。(c) 2008 Elsevier B.V.版权所有
People will often look to empty, uninformative locations in the world when trying to recall spoken information. This spatial indexing behaviour occurs when the information had previously been associated with those locations. It remains unclear, however, whether this behaviour is an example of a simple association across perceptual and cognitive systems, or whether location information plays a role in memory retrieval. In the current study, we investigate whether higher-level cognitive processes, such as object-based attention, are involved in spatial indexing. Participants saw creatures burrowing around the screen, appearing from underground to tell them facts. They saw the same creature in two locations, or two identical creatures in two locations, depending on spatiotemporal cues conveyed by a burrowing animation. While answering questions, we found that participants relied on these spatioternporal cues, fixating the previous locations of the creature associated with the relevant fact, rather than the location of an identical creature. We interpret these findings in terms of an object-based attentional mechanism that is common to semantic memory and scene perception, and allows,external memory' to be exploited in a dynamic environment.
