Abstract：
It is well known that attention is captured by salient objects or events. The notion that attention is attracted by salience information present in the visual field is also at the heart of many influential models of attention. These models typically posit a hierarchy of saliency, suggesting that attention progresses from the most to the least salient item in the visual field. However, despite the significance of this claim in various models, research on eye movements challenges the idea that search strictly follows this saliency hierarchy. Instead, eye-tracking studies have suggested that saliency information has a transient impact, only influencing the initial saccade toward the most salient object, and only if executed swiftly after display onset. While these findings on overt eye movements are important, they do not address covert attentional processes occurring before a saccade is initiated. In the current series of experiments, we explored whether there was evidence for secondary capture-whether attention could be captured by another salient item after the initial capture episode. To explore this, we utilized displays with multiple distractors of varying levels of saliency. Our primary question was whether two distractors with different saliency levels would disrupt search more than a single, highly salient distractor. Across three experiments, clear evidence emerged indicating that two distractors interfered more with search than a single salient distractor. This observation suggests that following initial capture, secondary capture by the next most salient distractor occurred. These findings collectively support the idea that covert attention traverses the saliency hierarchy. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
摘要：
众所周知,注意力是由显著对象或事件捕获的。视觉领域中存在的显著信息吸引注意力的概念也是许多有影响力的注意力模型的核心。这些模型通常假定显著性的层次结构，这表明注意力从视野中最突出的项目发展到最不突出的项目。然而,尽管这种说法在各种模型中具有重要意义，对眼球运动的研究挑战了搜索严格遵循这种显著性层次的想法。相反，眼动追踪研究表明，显著性信息具有短暂的影响，只会影响到最突出物体的初始扫视，并且仅在显示开始后迅速执行。虽然这些关于明显眼球运动的发现很重要，它们没有解决在扫视开始之前发生的秘密注意过程。在目前的一系列实验中,我们探讨了是否存在二次捕获的证据-在初次捕获发作后是否可以通过另一个显著项目捕获注意力.为了探索这个，我们利用具有不同显著性水平的多个干扰物的显示。我们的主要问题是，两个具有不同显着性水平的干扰因素是否会比单个干扰干扰搜索更多，高度突出的分心者。在三个实验中，有明确的证据表明，两个干扰物对搜索的干扰比单个干扰物的干扰更大。这一观察表明，在最初捕获之后，发生了下一个最突出的干扰物的二次捕获。这些发现共同支持了隐蔽注意力贯穿显著性层次的观点。（PsycInfo数据库记录（c）2024APA，保留所有权利)。
