Extant models of visual attention predict that a salient element should produce a bottom-up activation leading to a stimulus-driven attentional capture (e.g. Cave, 1999). However, apart from onset, previous works manipulating set-size in visual search failed to provide empirical evidence for this kind of capture. By varying target-singelton distance method, based on a single set-size, we explored whether, in a serial search task, an attentional capture is triggered by static discontinuities such as those generated through the manipulation of color, form, and luminance. The results suggest that those physical properties are indeed able to capture attention automatically.
现有的视觉注意模型预测，一个显著元素应该产生自下而上的激活，从而导致刺激驱动的注意捕获（例如，Cave，1999）。然而，除了起始之外，之前在视觉搜索中操纵集合大小的研究未能为这种捕获提供实证证据。通过基于单个集合大小改变目标-单元素距离方法，我们探究了在序列搜索任务中，诸如通过颜色、形状和亮度操纵所产生的静态不连续性是否会触发注意捕获。结果表明，那些物理属性确实能够自动捕获注意。
