当注意力被投入到一项任务中时，视觉场景中的意外事件可能不会被发现，这种现象被称为无意视盲（IB）。在信息处理的哪个阶段必须注意IB的发生？虽然操纵税视觉空间的注意力可以诱导IB，证据是更模棱两可的任务，在后期，中央阶段的信息处理。在这里，我们测试了IB是否可以专门由中央执行过程引起。一个意想不到的视觉刺激期间的工作记忆任务，涉及简单地保持口头材料或重新排列的材料成字母顺序的保留间隔。意外的刺激更容易被错过在操纵过程中比在简单的维护的口头信息。因此，执行过程的参与损害了检测意外的、与任务无关的刺激的能力，这表明IB可能来自中央的、非模态的处理阶段。
When attention is engaged in a task, unexpected events in the visual scene may go undetected, a phenomenon known as inattentional blindness (IB). At what stage of information processing must attention be engaged for IB to occur? Although manipulations that tax visuospatial attention can induce IB, the evidence is more equivocal for tasks that engage attention at late, central stages of information processing. Here, we tested whether IB can be specifically induced by central executive processes. An unexpected visual stimulus was presented during the retention interval of a working memory task that involved either simply maintaining verbal material or rearranging the material into alphabetical order. The unexpected stimulus was more likely to be missed during manipulation than during simple maintenance of the verbal information. Thus, the engagement of executive processes impairs the ability to detect unexpected, task-irrelevant stimuli, suggesting that IB can result from central, amodal stages of processing.
