尽管早期研究表明对非空间特征（即红色）的注意力仅限于出现在所关注的空间位置的刺激，但最近的研究强调了基于特征的注意力的全局性质。例如，共享目标特征的干扰物可能会引起注意，即使它发生在与任务无关的位置。这些发现被用来证明基于特征的注意力独立于空间注意力而运作。然而，基于特征的注意力仍然可以与空间注意力相互作用，在有人参与的位置比无人参与的位置产生更大的基于特征的效果。本研究测试了这种可能性。在两个实验中，参与者观看了快速串行视觉呈现 (RSVP) 流，并识别了由其颜色定义的目标字母。在 RSVP 直播期间，目标颜色的干扰物出现在各个与任务无关的位置。我们发现，当目标颜色的干扰物更接近关注位置时，特征驱动的注意力捕获效果最大。这些结果表明，空间注意力调节基于特征的注意力捕获的强度，这对基于特征的注意力以独立于空间注意力的全局方式运作的先前证据提出了质疑。
Although early research suggested that attention to nonspatial features (i.e., red) was confined to stimuli appearing at an attended spatial location, more recent research has emphasized the global nature of feature-based attention. For example, a distractor sharing a target feature may capture attention even if it occurs at a task-irrelevant location. Such findings have been used to argue that feature-based attention operates independently of spatial attention. However, feature-based attention may nonetheless interact with spatial attention, yielding larger feature-based effects at attended locations than at unattended locations. The present study tested this possibility. In two experiments, participants viewed a rapid serial visual presentation (RSVP) stream and identified a target letter defined by its color. Target-colored distractors were presented at various task-irrelevant locations during the RSVP stream. We found that feature-driven attentional capture effects were largest when the target-colored distractor was closer to the attended location. These results demonstrate that spatial attention modulates the strength of feature-based attention capture, calling into question the prior evidence that feature-based attention operates in a global manner that is independent of spatial attention.
