虽然关于世界的语义信息的使用似乎在我们执行的每一项任务中都无处不在，但当我们在特定的场景上下文（例如，客厅里的钥匙）中搜索东西时，我们是否依赖场景的语义信息来引导注意力还不清楚。为了解决这个问题，我们比较了场景语义信息（即场景主旨）与学习到的对象和上下文之间的空间关联的贡献。使用Castelhano和Henderson （Journal of Experimental Psychology: Human Perception and Performance 33:753-763, 2007）的闪-预览-移动窗口范式，参与者搜索放置在一致或不一致位置的目标物体，并且在语义上与场景要点一致或不一致。结果表明，即使在不一致的背景下，习得的空间关联也可以用来指导搜索，这证明了在没有一致的场景主旨信息的情况下，场景背景会影响搜索性能。我们从场景情境自上而下影响的层次组织角度讨论了结果。
Although the use of semantic information about the world seems ubiquitous in every task we perform, it is not clear whether we rely on a scene's semantic information to guide attention when searching for something in a specific scene context (e. g., keys in one's living room). To address this question, we compared contribution of a scene's semantic information (i.e., scene gist) versus learned spatial associations between objects and context. Using the flash-preview-moving-window paradigm Castelhano and Henderson (Journal of Experimental Psychology: Human Perception and Performance 33:753-763, 2007), participants searched for target objects that were placed in either consistent or inconsistent locations and were semantically consistent or inconsistent with the scene gist. The results showed that learned spatial associations were used to guide search even in inconsistent contexts, providing evidence that scene context can affect search performance without consistent scene gist information. We discuss the results in terms of hierarchical organization of top-down influences of scene context.
