在一系列的四个实验中，我们调查的条件下，目标缺席的反应比目标存在的反应更快的视觉搜索。先前的实验表明，这种缺席优势主要发生在均匀的干扰项排列成规则的模式。从这些结果中，可以得出结论，缺席优势是由于知觉过程，如分组的相似性。我们的数据表明，这些过程是不够的。相反，缺席优势是感知和决策过程相互作用的结果。某些感知条件，如随机刺激模式，导致产生缺席优势的特定标准设置。这样一个帐户可以解释我们的主要结果是证明了我们的数据与指导搜索2模型的修改版本建模。
In a series of four experiments, we investigated the conditions under which target-absent responses are faster than target-present responses in visual search. Previous experiments have shown that such an absent-advantage occurs mainly for homogeneous distracters arranged in a regular pattern. From these results, it has been concluded that the absent-advantage is due to perceptual processes, such as grouping by similarity. Our data show that such processes are not sufficient. Rather, the absent-advantage is the result of interactions between perceptual and decisional processes. Certain perceptual conditions, such as randomizing stimulus patterns, lead to specific criteria settings that produce an absent-advantage. That such an account can explain our main results is demonstrated by modeling our data with a modified version of the Guided Search 2 model.
