在几个实验中，观察者看到了 4 字数组。在每个阵列之后测试单词本地化的准确性。有些词，叫做熟悉，在一系列阵法中出现过很多次；另一些则被称为小说，只出现过一次。数组中新词与熟悉词的比例范围为 0:4 到 4:0。当熟悉词和新词不混合时（在 0:4 和 4:0 数组中），熟悉词的定位精度更高。然而，当它们混合时，尤其是在 1:3 阵列中，新词的准确率往往会更高。这种新颖的弹出效应是熟悉单词的定位性受到抑制（相对于 0:4 基线）和新单词的定位性增强（相对于 4:0 基线）的结果。新奇的弹出可能反映了注意力的自动定向，从感知领域更流畅展开的区域（熟悉的对象）转向不太流畅展开的区域（新奇的对象）。
In several experiments, observers were given glimpses of 4-word arrays. Accuracy of word localization was tested after each array. Some words, called familiar, appeared many times across the series of arrays; others, called novel, appeared only once. The ratio of novel to familiar words in an array ranged from 0: 4 to 4: 0. When familiar and novel words were not intermixed (in 0: 4 and 4: 0 arrays), localization accuracy was higher for familiar words. However, when they were intermixed, especially in 1: 3 arrays, accuracy tended to be higher for the novel words. This novel popout effect was the outcome of the suppressed localizability of the familiar words (relative to the 0: 4 baseline) and the enhanced localizability of the novel words (relative to the 4: 0 baseline). Novel popout may reflect an automatic orientation of attention away from more fluently unfolding regions of the perceptual field (familiar objects) and toward less fluently unfolding regions (novel objects).
