在两个实验中，我们研究了一个新物体的出现是否比消失具有注意优先级。以前未能显示差异可能是由于起始和偏移始终作为唯一的视觉瞬态呈现。而不是单独提出每一个，我们提出了发病和偏移单例同时与显示器范围内的亮度瞬态，以迫使每个竞争与其他视觉事件。从实验1的结果表明，目标与发病累积反应时间的好处，而目标与偏移量没有。实验2表明，即使当观察者注意力集中寻找偏移时，发作也会引起注意。相比之下，补偿需要一个相关的注意力设置，以吸引注意力。我们认为，一个物体的出现有注意力优先于消失。
In two experiments we examined whether the appearance of a new object has attentional priority over disappearance. Previous failures to show differences are possibly due to onsets and offsets always being presented as a sole visual transient. Rather than presenting each alone, we presented onset and offset singletons simultaneously with a display-wide luminance transient in order to force each to compete with other visual events. Results from Experiment 1 showed that targets associated with onsets accrued a reaction time benefit whilst targets associated with offsets did not. Experiment 2 showed that onsets attracted attention even when observers were attentionally set to look for offset. By contrast, offsets needed a relevant attentional set in order to attract attention. We argue that the appearance of an object has attentional priority over disappearance.
