When a visual target is identified, there is a period of several hundred milliseconds when the processing of subsequent targets is impaired, a phenomenon labeled the attentional blink (AB). The emerging consensus is that the identification of a visual target temporarily occupies a limited attentional resource that is essential for all visual perception. The present results challenge this view. With the same digit discrimination task that impaired subsequent letter discrimination for several hundred milliseconds, we found no disruption of subsequent face discrimination. These results suggest that all stimuli do not compete for access to a single resource for visual perception. We propose a multi-channel account of interference in the AB paradigm.
当识别出一个视觉目标时，会有几百毫秒的时间段，在此期间对后续目标的处理会受到损害，这种现象被称为注意瞬脱（AB）。新出现的共识是，视觉目标的识别会暂时占用一种有限的注意资源，而这种资源对于所有视觉感知来说都是必不可少的。目前的结果对这一观点提出了挑战。在相同的数字辨别任务中，该任务在几百毫秒内损害了后续字母辨别，而我们发现后续面部辨别没有受到干扰。这些结果表明，并非所有刺激都竞争获取单一的视觉感知资源。我们提出了一种关于注意瞬脱范式中干扰的多通道解释。
