本研究采用注意眨眼（AB）范式来研究视觉标记所需的注意资源。结果表明，尽管参与者预期未来的目标显示，但在AB内呈现的干扰物不易被忽视。这支持了视觉标记需要注意力资源的假设。此外，探测点在眨眼的干扰物上比在成功忽略的干扰物上被更好地检测到，但只有在任务需要优先考虑新项目的情况下。在最后的实验中，与在AB外呈现的干扰物相同的目标出现了更强的负传递效应，而不是在AB内。这表明至少部分与视觉标记有关的抑制过程是非空间的。
An attentional blink (AB) paradigm was used to investigate the attentional resources necessary for visual marking. The results showed that distractors presented inside the AB cannot easily be ignored despite participants anticipating a future target display. This supports the hypothesis that attentional resources are required for visual marking. In addition, probe dots were better detected on blinked distractors than on successfully ignored distractors, but only when the task required new items to be prioritized. In a final expriment, a stronger negative carry-over effect on search occurred for targets identical to distractors presented outside rather than inside the AB. This suggests that at least part of the inhibitory processes involved in visual marking are nonspatial.
