有相当多的证据表明，显著项目可以被抑制，以防止注意捕获。然而，这一证据几乎完全依赖于使用颜色单例作为显着干扰的范例。因此，目前还不清楚其他类型的显著刺激，如突然发作，是否也可以被抑制。使用一个额外的单例范式优化检测眼抑制，我们直接比较颜色单例突然发作。参与者搜索目标形状（例如，绿色菱形），并试图忽略突然出现或颜色单一的显著干扰。首先，眼球运动被用来评估是否突出的干扰捕获注意力或反而被抑制。最初的实验使用一种类型的突然发作的经典注意力捕获研究（四个白色点）显示，突然发作强烈捕获的注意力，而颜色单例被抑制。在控制了起始和颜色单例之间的重要差异（如亮度和颜色）后，起始捕获减少但未消除。我们最终得出结论，突然发作不像颜色单例抑制。
There is considerable evidence that salient items can be suppressed in order to prevent attentional capture. However, this evidence has relied almost exclusively on paradigms using color singletons as salient distractors. It is therefore unclear whether other kinds of salient stimuli, such as abrupt onsets, can also be suppressed. Using an additional singleton paradigm optimized for detecting oculomotor suppression, we directly compared color singletons with abrupt onsets. Participants searched for a target shape (e.g., green diamond) and attempted to ignore salient distractors that were either abrupt onsets or color singletons. First eye movements were used to assess whether salient distractors captured attention or were instead suppressed. Initial experiments using a type of abrupt onset from classic attentional capture studies (four white dots) revealed that abrupt onsets strongly captured attention whereas color singletons were suppressed. After controlling for important differences between the onsets and color singletons - such as luminance and color - abrupt-onset capture was reduced but not eliminated. We ultimately conclude that abrupt onsets are not suppressed like color singletons.
