在快速的视觉刺激流中检测到目标项目后，有400-600毫秒的周期在此期间遗漏了随后的目标。这种障碍已被标记为“注意力眨眼”（1）。已经提出，与眼睛眨眼不同，附加的眨眼不能反映对感知处理的抑制，而是反映了在听觉后阶段的信息丧失，例如视觉短期记忆（2-4）。在这里，我们提供了电生理学证据，表明在注意力眨眼期间呈现的单词被分析至含义提取点，即使这些提取的含义不能在1-2之后报告。这表明，注意力眨眼确实确实反映了在处理后处理阶段的信息丧失，并提供了人脑功能模块化的证明。
AFTER the detection of a target item in a rapid stream of visual stimuli, there is a period of 400-600 ms during which subsequent targets are missed. This impairment has been labelled the 'attentional blink'(1). It has been suggested that, unlike an eye blink, the additional blink does not reflect a suppression of perceptual processing, but instead reflects a loss of information at a postperceptual stage, such as visual short-term memory(2-4). Here we provide electrophysiological evidence that words presented during the attentional blink period are analysed to the point of meaning extraction, even though these extracted meanings cannot be reported 1-2 s later. This shows that the attentional blink does indeed reflect a loss of information at a postperceptual stage of processing, and provides a demonstration of the modularity of human brain function.
