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.

有相当多的证据表明可以抑制突出的项目以防止注意力捕获。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因素的范例。因此，尚不清楚是否也可以抑制其他类型的显着刺激，例如突然发作。使用为检测动眼神经抑制而优化的附加单例范例，我们直接比较了颜色单例与突然发作。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着干扰因素。第一眼球运动被用来评估突出的干扰因素是引起注意还是被抑制。使用经典注意力捕获研究（四个白点）中的一种突然开始的初始实验表明，突然开始强烈地吸引了注意力，而颜色单一被抑制了。在控制了起始和颜色单例之间的重要差异（例如亮度和颜色）之后，突然发生的捕获减少但没有消除。我们最终得出结论，突然发作不像颜色单例那样被抑制。
