本研究比较了中等复杂显示中物体出现（出现）和消失（消失）对注意力的影响。四个实验表明，起动产生抑制返回（IOR）效应，已经发现在简单的显示。相比之下，虽然抵消确实产生了抑制作用，但这些作用并不遵循IOR的空间或时间模式。两个进一步的实验使用了一个非常显著的对象消失来确定是否可以实例化IOR的典型模式，结果是不能的。结果表明，物体出现是比物体消失更有效的知觉事件。此外，客体消失与客体出现具有不同的注意后果：客体消失引起更早和空间范围更窄的抑制。结果与抑制在提高视觉搜索过程效率方面起功能作用的观点一致。
This study compared the attentional effects of object appearances (onsets) and disappearances (offsets) in moderately complex displays. Four experiments showed that onsets produce the inhibition of return (IOR) effect that has been found with simpler displays. In contrast, although offsets did produce inhibitory effects, these effects did not follow the spatial or temporal pattern of IOR. Two further experiments used a very salient object disappearance to determine whether the typical pattern for IOR could be instantiated, it was not. The results indicate that object appearances are more potent perceptual events than object disappearances. In addition, object disappearances have different attentional consequences than object appearances: Disappearances provoke earlier and spatially narrower inhibition. The results are consistent with the view that inhibition serves a functional role in increasing the efficiency of visual search processes.
