注意视野中的一个位置有助于处理该位置中的物体，并且许多研究已经揭示了通过预先确定目标位置的处理益处。最近的研究还表明，预先设定一个位置可以减少该位置的项目的干扰;然而，预先设定一个特征（颜色）可以忽略会增加干扰物的干扰，至少在建立拒绝模板之前。因此，可以选择性地忽略位置而不是特征。本研究使用空间提示任务来检查当特征相关的项目出现在被忽视的位置时是否会被选择。结果显示，目标相关的线索（红色线索时，搜索红色目标，但不是发病目标），即使当线索出现在一个位置，被忽略的条件注意捕获。重要的是，这相当于由非忽略位置的线索引起的偶然捕获。然而，当观察员被预先安排到目标地点时，特遣队俘虏基本上就消除了。结果表明，具有目标相关特征的突出项目是从选择性忽略的位置中选择的，但是将注意力集中到一个位置上可以排除突出和目标相关项目的捕获。
Attending to a location in the visual field facilitates processing of objects in that location, and numerous studies have revealed processing benefits by precuing target locations. Recent studies have also demonstrated that precuing a location to ignore reduces distraction by items in that location; however, precuing a feature (colour) to ignore increases distractor interference, at least before a template for rejection is established. Thus, locations, not features, can be selectively ignored. The present study used a spatial cuing task to examine whether featurally-relevant items are selected when they appear in ignored locations. The results revealed contingent attentional capture by target-relevant cues (red cue when searching for red targets, but not for onset targets), even when the cue appeared in a location that was ignored. Importantly, this was equivalent to contingent capture elicited by cues in non-ignored locations. However, when observers were precued to the target location, contingent capture was largely eliminated. The results suggest salient items with target-relevant features are selected from selectively ignored locations, but focusing attention onto a location can preclude capture by salient and target-relevant items.
