通常认为，搜索中显著视觉对象的有效检测反映了刺激驱动的注意捕获。然而，这一假设的证据来自于那些突出对象与任务相关的任务，因此可能会引起有意识的注意力部署。在9个实验中，被试搜索一个非显著目标（倾斜条中的垂直条）。在每个显示器中，1条在不同的维度（例如，颜色或运动）上非常突出。当目标和显著因素很少重合时，减少了刻意关注显著刺激的动机，反应时间与目标是否显著无关，尽管观察到一些有趣的例外情况。结论是，视觉搜索中元素的有效选择并不构成元素以纯粹刺激驱动的方式捕获注意力的证据。
It is often assumed that the efficient detection of salient visual objects in search reflects stimulus-driven attentional capture. Evidence for this assumption, however, comes from tasks in which the salient object is task relevant and therefore may elicit a deliberate deployment of attention. In 9 experiments, participants searched for a nonsalient target (vertical among tilted bars). In each display, 1 bar was highly salient in a different dimension (e.g., color or motion). When the target and salient elements coincided only rarely, reducing the incentive to attend deliberately to the salient stimuli, response times depended little on whether the target was salient, although some interesting exceptions were observed. It is concluded that efficient selection of an element in visual search does not constitute evidence that the element captures attention in a purely stimulus-driven fashion.
