进行了六个实验来检查目标知识对简单搜索任务（实验 1-3）和复合搜索任务（实验 4-6）中压倒刺激驱动干扰的影响。在简单搜索中，当目标与非目标的方向不同时，具有与目标相同方向的单一干扰物会干扰对目标的搜索。当就目标定义特征而言，单例干扰物不如目标显着时，它仍然会造成干扰。这种维度内、基于非显着性的干扰也发生在复合搜索任务中。相比之下，当在简单的搜索任务中跨维度定义单例干扰项时，不会发生干扰。当使用复合搜索任务时，显着的干扰因素会干扰对不太显着的目标的搜索。这些结果讨论了它们对现有模型的适用性以及特征处理阶段自上而下的渗透性的局限性。
Six experiments were conducted to examine the effect of knowledge of a target for overriding stimulus-driven interference in simple search tasks (Experiments 1-3) and compound search tasks (Experiments 4-6). In simple search when the target differed from nontargets in orientation, a singleton distracter that had an orientation equivalent to that of a target interfered with search for the target. When the singleton distracter was less salient than the target with respect to the target-defining feature, it still caused interference. Such within-dimensional, nonsaliency-based interference also occurred in compound search tasks. In contrast, no interference occurred when a singleton distracter was defined in cross-dimension in a simple search task. When a compound search task was used, the salient distracter interfered with the search for a less salient target. These results are discussed in tenus of their applicability to existing models and the limitations of top-down penetrability of a feature processing stage.
