观察者可以在视觉长时记忆中以高保真的方式存储数以千计的物体图像，但场景表征在长时记忆中的保真度尚不清楚。在这里，我们通过改变不同场景类别中的研究样本的数量，并使用样本级别的箔来测试记忆，来探索场景表征的保真度。观察者在5.5小时内观看了数千个场景，然后完成了一系列强制选择测试。记忆性能很高，即使是同一类别的场景也是如此。此外，所研究的场景样本每增加一倍，准确率只会下降2%。令人惊讶的是，这种分类干扰的程度与之前展示的物体记忆的程度相似。因此，尽管场景通常被定义为对象的超集，但我们的结果表明，场景和对象可能是视觉长期记忆中类似抽象水平的实体。
Observers can store thousands of object images in visual long-term memory with high fidelity, but the fidelity of scene representations in long-term memory is not known. Here, we probed scene-representation fidelity by varying the number of studied exemplars in different scene categories and testing memory using exemplar-level foils. Observers viewed thousands of scenes over 5.5 hr and then completed a series of forced-choice tests. Memory performance was high, even with up to 64 scenes from the same category in memory. Moreover, there was only a 2% decrease in accuracy for each doubling of the number of studied scene exemplars. Surprisingly, this degree of categorical interference was similar to the degree previously demonstrated for object memory. Thus, although scenes have often been defined as a superset of objects, our results suggest that scenes and objects may be entities at a similar level of abstraction in visual long-term memory.
