有人提出，最大和最小的目标（如最亮或最亮的项目的样本）被发现通过不同的搜索过程，后者，而不是前者是敏感的焦点注意撤回。目前的研究不能建立这样一个系统的差异，并建议在搜索性能的变化是由于目标显着性的变化。暗干扰物中的亮目标通常比亮干扰物中的暗目标更显著（实验1）。在这两种情况下，搜索性能恶化时，注意力被撤回（实验2）。性能变得相同时，最大和最小的目标相匹配的显着性，这也证实了明亮的背景上的黑暗项目（实验3）。这些数据强调了视觉搜索中的显着性的重要性，但不支持的假设，最大和最小的目标搜索是定性不同的焦点注意力的要求。在视觉搜索中，显著性和注意力似乎是互补的功能;目标越不显著，就需要越多的注意力来检测它。
It has been proposed that maximum and minimum targets (like the brightest or the least-bright item of a sample) are found by different search processes, the latter but not the former being sensitive to the withdrawal of focal attention. The present study could not establish such a systematic difference and suggests that variations in search performance are due to variations in target salience. Bright targets among dim distractors were generally more salient than dim targets among bright dis-tractors (Experiment 1). In both conditions, search performance was deteriorated when attention was withdrawn (Experiment 2). Performance became identical when maximum and minimum targets were matched in salience; this was also confirmed for dark items on bright background (Experiment 3). The data underline the importance of salience in visual search but do not support the assumption that maximum and minimum target searches are qualitatively different in their demands on focal attention. Salience and attention rather seem to resemble complementary functions in visual search; the less salient a target is the more attention is required to detect it.
