作者通过测量要针对新对象的眼睛的倾向来研究在现实世界中突然出现对象的优先级。新物体被固定在固定期间（瞬态打击）还是扫视（非传输量）中的频率更高。但是，在固定期间出现的on态被固定的时间比与扫视一致的人更快，更频繁。在扫视过程中的优先次序（而不是固定）受记忆操纵的影响：减少场景观看时间之前消除了优先级排序，而先前对场景的研究则增加了优先级。瞬态对象会迅速吸引注意力，并不依赖内存，但是如果没有瞬态信号，新对象将优先于几个扫视，因为内存用于明确识别更改。观察者对新对象出现的期望并没有调节这些效果，这表明瞬态的优先级是自动的，并且记忆引导的优先级是隐含的。
The authors examined the prioritization of abruptly appearing objects in real-world scenes by measuring the eyes' propensity to be directed to the new object. New objects were fixated more often than chance whether they appeared during fixations (transient onsets) or saccades (nontransient onsets). However, onsets that appeared during fixations were fixated sooner and more often than those coincident with saccades. Prioritization of onsets during saccades, but not fixations, were affected by manipulations of memory: Reducing scene viewing time prior to the onset eliminated prioritization, whereas prior study of the scenes increased prioritization. Transient objects draw attention quickly and do not depend on memory, but without a transient signal, new objects are prioritized over several saccades as memory is used to explicitly identify the change. These effects were not modulated by observers' expectations concerning the appearance of new objects, suggesting the prioritization of a transient is automatic and that memory-guided prioritization is implicit.
