观察者通常比边缘对象更容易检测到中心对象的变化，但他们有时也会错过中心对象的变化。然而，即使观察者没有报告这样的变化，他们也可能能够识别出变化的对象。在三个实验中，我们探讨了变化检测和识别记忆的几种类型的变化，在电影中的中心对象。观察员谁没有检测到的变化仍然执行上述机会水平的识别任务，在几乎所有的条件。此外，发现变化的观察者并不比那些没有发现变化的人更准确地识别。尽管在不同条件下变化的可检测性存在很大差异，但那些错过变化的观察者在识别变化物体的能力上并没有变化。
Observers typically detect changes to central objects more readily than changes to marginal objects, but they sometimes miss changes to central, attended objects as well. However, even if observers do not report such changes, they may be able to recognize the changed object. In three experiments we explored change detection and recognition memory for several types of changes to central objects in motion pictures. Observers who failed to detect a change still performed at above chance levels on a recognition task in almost all conditions. In addition, observers who detected the change were no more accurate in their recognition than those who did not detect the change. Despite large differences in the detectability of changes across conditions, those observers who missed the change did not vary in their ability to recognize the changing object.
