部分报告方法已经表明，大容量表示在图片消失后存在数百毫秒。然而，改变失明研究表明，当随后呈现图像的改变版本时，仍然可以获得的信息非常有限。大容量表示会发生什么情况？第一个图像之后的新输入可能会干扰，但这可能取决于新输入的特性。在我们的第一个实验中，我们证明了在变化的图像之间包含同质图像元素的显示器并不会使大容量表示不可用。当这些新元素定义对象时，会发生干涉。在此基础上，我们介绍了一种产生变化盲的新方法：第二个实验表明，通过重新定义图形和背景可以产生变化盲，而不需要在显示之间设置间隔。定义图形和背景的局部特征(线段)被交换，而图形的轮廓保持不变。通常，当没有间隔时，很容易检测到变化。然而，我们的范式导致了巨大的变化盲目。我们认为，在变化盲实验中，当原始图像被均匀间隔显示时，原始图像有一个大容量的表示，但当变化的图像迫使图形与背景重新分离时，就会发生变化盲。
Partial report methods have shown that a large-capacity representation exists for a few hundred milliseconds; after a picture has disappeared. However, change blindness studies indicate that very limited information remains available when a changed version of the image is presented subsequently. What happens to the large-capacity representation? New input after the first image may interfere, but this is likely to depend on the characteristics of the new input. In our first experiment, we show that a display containing homogeneous image elements between changing images does not render the large-capacity representation unavailable. Interference occurs when these new elements define objects. On that basis we introduce a new method to produce change blindness: The second experiment shows that change blindness can be induced by redefining figure and background, without an interval between the displays. The local features (line segments) that defined figures and background were swapped, while the contours of the figures remained where they were. Normally, changes are easily detected when there is no interval. However, our paradigm results in massive change blindness. We propose that in a change blindness experiment, there is a large-capacity representation of the original image when it is followed by a homogeneous interval display, but that change blindness occurs whenever the changed image forces resegregation of figures from the background.
