Duncan，Ward，and Shapiro(1994)估计，在将注意力转移到另一个物体之前，注意力必须在一个物体上保持几百毫秒，他们将这段时间称为驻留时间的注意力。对视觉搜索模型的停留时间的这些长估计的一个重要含义是，搜索过程不能涉及逐个项目的连续扫描机制。如果是，那么搜索一系列物品将需要大量的时间，但根据视觉搜索实验的数据，这并不是，但本报告提供的证据表明，注意力停留时间的长估计至少部分是由使用蒙面目标造成的。讨论了注意停留时间的这些变量估计对视觉搜索模型的影响。
Duncan, Ward, and Shapiro (1994) estimated that attention must remain focused on an object for several hundred milliseconds before being shifted to another object, and they referred to this period as the attention at dwell time. An important implication of these long estimates of the dwell time for models of visual search is that the search process must not involve an item-by-item serial scanning mechanism. If it did, then searching through an array of items would require enormous amounts of time, which-based on data from visual search experiments-it does not, The present report, however, provides evidence that the long estimates of attentional dwell time were caused, at least in part, by the use of masked targets. Implications of these variable estimates of the attentional dwell time for models of visual search are discussed.
