在上下文线索范式，我们研究了如何记忆的空间结构的自然场景引导视觉搜索。参与者通过嵌入在真实世界场景中的物体阵列进行搜索。如果一个重复的搜索阵列与一个单一的场景在研究过程中，然后阵列重复产生显着的上下文线索。然而，这种学习的表达依赖于实例化学习发生的原始场景：当重复的数组被转移到不同的场景时，上下文提示被破坏。然而，这种特定场景的学习并不是绝对的。在高场景可变性的条件下，独立于场景背景学习重复搜索阵列。这些数据表明，当一个一致的环境结构是可用的，支持视觉搜索的空间表示层次化组织，与内存嵌套在一个代表性的更大的场景的环境的功能子区域。
In a contextual cuing paradigm, we examined how memory for the spatial structure of a natural scene guides visual search. Participants searched through arrays of objects that were embedded within depictions of real-world scenes. If a repeated search array was associated with a single scene during study, then array repetition produced significant contextual cuing. However, expression of that learning was dependent on instantiating the original scene in which the learning occurred: Contextual cuing was disrupted when the repeated array was transferred to a different scene. Such scene-specific learning was not absolute, however. Under conditions of high scene variability, repeated search array were learned independently of the scene background. These data suggest that when a consistent environmental structure is available, spatial representations supporting visual search are organized hierarchically, with memory for functional subregions of an environment nested within a representation of the larger scene.
