许多研究已经研究了前注意视觉：注意力到达之前的视觉表征。大多数视觉研究关注注意视觉刺激，很少有研究考虑后注意视觉。当注意力转移到其他地方时，先前关注的对象的视觉表征是什么？作者认为，一旦注意力被重新部署，注意力的感知效果就会消失。实验1-6为视觉搜索研究。在标准搜索中，参与者在干扰项中寻找目标项。在每次试验中，均显示新的检索显示。这些任务进行了比较，重复的搜索任务中，搜索显示没有改变。在连续的试验中，参与者搜索相同的显示新的目标。结果表明，如果参与者第一次搜索显示器时搜索效率低下，那么当第二次，第五次或第350次搜索相同的，不变的显示器时，搜索效率低下。实验7和实验8采用曲线追踪范式提出了类似的观点。这些结果对理解场景感知、变化检测以及视觉与记忆的关系具有重要意义。（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
Much research has examined preattentive vision: visual representation prior to the arrival of attention. Most vision research concerns attended visual stimuli; very little research has considered postattentive vision. What is the visual representation of a previously attended object once attention is deployed elsewhere? The authors argue that perceptual effects of attention vanish once attention is redeployed. Experiments 1–6 were visual search studies. In standard search, participants looked for a target item among distractor items. On each trial, a new search display was presented. These tasks were compared to repeated search tasks in which the search display was not changed. On successive trials, participants searched the same display for new targets. Results showed that if search was inefficient when participants searched a display the first time, it was inefficient when the same, unchanging display was searched the second, fifth, or 350th time. Experiments 7 and 8 made a similar point with a curve tracing paradigm. The results have implications for an understanding of scene perception, change detection, and the relationship of vision to memory.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
