在常见的“注意力”任务中，需要在形成快速按键响应之前进行刺激身份处理，空间启动效应取决于响应重复。通常，当先前的响应重复时，刺激位置的重复是有利的，但当先前的响应改变时，刺激位置的重复是不利的或无关紧要的。响应和空间之间的这种联系使得很难从两个选择的按键任务中推断出注意力偏差。相反，这些发现是由情景检索理论解释的，该理论认为，当后面的刺激占据其空间时，与先前刺激位置相关的反应就会被检索。如果需要事先响应，则此检索操作是有利的，否则则不然，这解释了典型的模式。这种观点促使我们评估视觉搜索文献中的空间启动效应是否严重依赖于反应重复。为了评估这一点，我们重新评估了 Tower-Richardi、Leber 和 Golomb 最近发表的一系列实验（Attention, Perception, & Psychophysicals, 78(1), 114-132, 2016）。他们的目标是确定视觉搜索显示空间启动的参考系。重新评估表明，当空间主题、视网膜主题和以物体为中心的参考系完全混杂时，空间启动强烈依赖于反应重复。然而，当进行眼球运动以将空间主题和以物体为中心的参考系与视网膜主题参考系分离时，空间启动是积极的并且不受反应重复的影响。研究结果表明，至少有两个不同的过程影响视觉搜索的空间启动，这些过程发生在不同的表征水平上。
In common "attention" tasks, which require stimulus-identity processing prior to the formation of a speeded key-press response, spatial priming effects depend on response repetition. Typically, the repetition of a stimulus location is advantageous when the prior response repeats, but disadvantageous or inconsequential when the prior response changes. This link between responding and space makes it difficult to draw inferences about attentional bias from two-choice key-press tasks. Instead, the findings are accounted for by episodic retrieval theories, which argue that the response associated with a prior stimulus location is retrieved when a later stimulus occupies its space. This retrieval operation is advantageous if the prior response is needed but not otherwise, which explains typical patterns. This perspective motivated us to evaluate whether spatial priming effects in the visual-search literature depend critically on response repetition. To assess this, we reevaluated a series of experiments recently published by Tower-Richardi, Leber, and Golomb (Attention, Perception, & Psychophysics, 78(1), 114-132, 2016). Their goal was to determine the reference frame of spatial priming across visual search displays. Reassessment reveals that spatial priming was strongly dependent on response repetition when spatiotopic, retinotopic, and object-centered reference frames were perfectly confounded. However, when eye movements were made to dissociate the spatiotopic and object-centered reference frame from the retinotopic reference frame, spatial priming was positive and unaffected by response repetition. The findings demonstrate that at least two distinct processes factor into spatial priming across visual searches, which occur at different levels of representation.
