基于物体的注意力的证据通常来自使用不变物体的显示的研究，关于物体效应是否会通过改变物体显示或在试验中看到这种变化而改变，尚未达成共识。我们通过使用Egly等人[Egly，R.，司机，J，& Rafal，R. D.（1994年）。在物体和位置之间转移视觉注意力：来自正常和顶叶病变受试者的证据。Journal of Experimental Psychology：General，123，161-177]，而我们的结果，当物体保持不变时，复制了原始的物体效应。然而，当矩形在最后一帧（目标帧）中从视图中消失时，没有发现对象效果。无论矩形消失的可能性如何，这都是正确的，表明瞬时物体输入对于基于物体的注意力的重要性。然而，当提示矩形在整个试验中持续存在时，发现看到不同物体（回飞棒）的跨试验经验会影响物体效应。不同于以往的研究，强调一个或另一个，我们清楚地表明，瞬时对象输入和过去的经验相互作用，以确定注意力选择对象的方式。(C)2009 Elsevier B.

Evidence for object-based attention typically comes from studies using displays with unchanged objects, and no consensus has yet been reached as to whether the object effect would be altered by changing object displays or having seen this change across-trials. We examined this by using modifications of the double-rectangle cuing paradigm of Egly et al. [Egly, R., Driver, J., & Rafal, R. D. (1994). Shifting visual attention between objects and locations: Evidence from normal and parietal lesion subjects. Journal of Experimental Psychology: General, 123, 161-177], and our results, when the objects remained unchanging, replicated the original object effect. However, no object effect was found when the rectangles disappeared from view in the last (target) frame. This was true regardless of the likelihood of the rectangles disappearing, indicating the importance of instantaneous object inputs for object-based attention. The across-trial experience of seeing a different object (boomerang), however, was found to influence the object effect when the cued rectangles persisted throughout the trial. Unlike previous studies, which emphasize one or the other, we demonstrate clearly that instantaneous object inputs and past experience interact to determine the way attention selects objects.
