A large body of work suggests that the visual system is particularly sensitive to the appearance of new objects. This is based partly on evidence from visual search studies showing that onsets capture attention whereas many other types of visual event do not. Recently, however, the notion that object onset has a special status in visual attention has been challenged. For instance, an object that looms toward an observer has also been shown to capture attention. In two experiments, we investigated whether onset receives processing priority over looming. Observers performed a change detection task in which one of the display objects either loomed or receded, or a new object appeared. Results showed that looming objects were more resistant to change blindness than receding objects. Crucially, however, the appearance of a new object was less susceptible to change blindness than both looming and receding. We argue that the visual system is particularly sensitive to object onsets.
大量研究表明，视觉系统对新物体的出现尤为敏感。这部分基于视觉搜索研究的证据，该研究表明物体起始能吸引注意力，而许多其他类型的视觉事件则不然。然而，最近物体起始在视觉注意力中具有特殊地位这一观点受到了挑战。例如，一个朝着观察者逼近的物体也被证明能吸引注意力。在两项实验中，我们研究了物体起始是否比逼近在处理上具有优先级。观察者执行了一个变化检测任务，其中显示的物体之一要么逼近要么后退，或者出现一个新物体。结果表明，逼近的物体比后退的物体更不易产生变化盲视。然而，至关重要的是，新物体的出现比逼近和后退的物体都更不易产生变化盲视。我们认为视觉系统对物体起始特别敏感。
