我们研究了现实世界场景中突然出现和消失的对象的优先级。这些场景变化发生在固定（短暂的出现/消失）或扫视（非短暂的出现/消失）期间。优先级是通过眼睛指向场景变化区域的倾向来衡量的。物体的增加和删除被固定在率大于机会，这表明这两种类型的场景变化的线索，由视觉系统用来引导注意力在场景探索，虽然外观固定的两倍，经常消失，表明新的对象比删除的对象更显着。新的和删除的对象优先级更快，更频繁，如果他们发生在固定，相比，在扫视，表明一个重要的作用，往往伴随着场景的突然变化的瞬态信号。无论新对象是否出现在注视或扫视期间，都优先考虑它们，而删除对象的优先级仅在以下情况下发生：（1）存在瞬态信号或（2）对象的移除揭示了先前被遮挡的对象。
We examined the prioritization of abruptly appearing and disappearing objects in real-world scenes. These scene changes occurred either during a fixation (transient appearance/disappearance) or during a saccade (nontransient appearance/disappearance). Prioritization was measured by the eyes' propensity to be directed to the region of the scene change. Object additions and deletions were fixated at rates greater than chance, suggesting that both types of scene change are cues used by the visual system to guide attention during scene exploration, although appearances were fixated twice as often as disappearances, indicating that new objects are more salient than deleted objects. New and deleted objects were prioritized sooner and more frequently if they occurred during a fixation, as compared with during a saccade, indicating an important role of the transient signal that often accompanies sudden changes in scenes. New objects were prioritized regardless of whether they appeared during a fixation or a saccade, whereas prioritization of a deleted object occurred only if (1) a transient signal was present or (2) the removal of the object revealed previously occluded objects.
