人类甚至可以在一秒钟内理解复杂自然场景的“要点”。然而，如果要求观察者在一系列快速呈现的项目中检测目标，则对在大约三分之一秒之后的另一目标的识别严重受损，即“注意瞬脱”（AB）[Raymond，J.E.，Shapiro，K. L.，& Arnett，K. M.（1992年）。RSVP任务中视觉加工的暂时抑制：注意瞬脱？实验心理学杂志。Human Perception and Performance，18，849-860].由于大多数关于AB的实验都使用了控制良好但人为的刺激，因此出现了一个问题，即复杂的自然刺激是否会发生同样的现象，如果是这样，其具体情况是否取决于刺激类别。在这里，我们呈现了复杂刺激的快速序列（物体，场景和面孔的照片），并要求观察者检测和记住特定类别的项目（或者。手表，或两者）。我们发现一个一致的AB两个目标类别，但AB的持续时间取决于目标类别。(c)2006爱思唯尔有限公司保留所有权利。
Humans comprehend the "gist" of even a complex natural scene within a small fraction of a second. If, however, observers are asked to detect targets in a sequence of rapidly presented items, recognition of a target succeeding another target by about a third of a second is severely impaired, the "attentional blink" (AB) [Raymond, J. E., Shapiro, K. L., & Arnett, K. M. (1992). Temporary suppression of visual processing in an RSVP task: an attentional blink? Journal of Experimental Psychology. Human Perception and Performance, 18, 849-860]. Since most experiments on the AB use well controlled but artificial stimuli, the question arises whether the same phenomenon occurs for complex, natural stimuli, and if so, whether its specifics depend on stimulus category. Here we presented rapid sequences of complex stimuli (photographs of objects, scenes and faces) and asked observers to detect and remember items of a specific category (either. faces, watches, or both). We found a consistent AB for both target categories but the duration of the AB depended on the target category. (c) 2006 Elsevier Ltd. All rights reserved.
