The attentional prioritization hypothesis of object-based attention (Shomstein & Yantis in Perception & Psychophysics, 64, 41-51, 2002) suggests a two-stage selection process comprising an automatic spatial gradient and flexible strategic (prioritization) selection. The combined attentional priorities of these two stages of object-based selection determine the order in which participants will search the display for the presence of a target. The strategic process has often been likened to a prioritized visual search. By modifying the double-rectangle cueing paradigm (Egly, Driver, & Rafal in Journal of Experimental Psychology: General, 123, 161-177, 1994) and placing it in the context of a larger-scale visual search, we examined how the prioritization search is affected by search efficiency. By probing both targets located on the cued object and targets external to the cued object, we found that the attentional priority surrounding a selected object is strongly modulated by search mode. However, the ordering of the prioritization search is unaffected by search mode. The data also provide evidence that standard spatial visual search and object-based prioritization search may rely on distinct mechanisms. These results provide insight into the interactions between the mode of visual search and object-based selection, and help define the modulatory consequences of search efficiency for object-based attention.
基于客体的注意的注意优先级假说（Shomstein和Yantis，《知觉与心理物理学》，第64卷，第41 - 51页，2002年）提出了一个两阶段选择过程，包括自动空间梯度和灵活的策略性（优先级）选择。基于客体选择的这两个阶段的联合注意优先级决定了参与者在显示中搜索目标是否存在的顺序。策略性过程常被比作优先视觉搜索。通过修改双矩形提示范式（Egly、Driver和Rafal，《实验心理学杂志：总论》，第123卷，第161 - 177页，1994年）并将其置于更大规模视觉搜索的背景下，我们研究了优先级搜索如何受到搜索效率的影响。通过探测位于提示客体上的目标和提示客体外部的目标，我们发现围绕所选客体的注意优先级受到搜索模式的强烈调节。然而，优先级搜索的顺序不受搜索模式的影响。数据还提供了证据表明标准空间视觉搜索和基于客体的优先级搜索可能依赖于不同的机制。这些结果为视觉搜索模式与基于客体的选择之间的相互作用提供了见解，并有助于确定搜索效率对基于客体的注意的调节后果。
