外观自然变化的图画和几何图形有一种奇特的魅力。一个典型的例子是本页中透明立方体的线条画。\\然后你首先看这个立方体，它的一个面似乎在前面，另一个面在后面。然后如果你稳定地看这幅画一会儿，它会突然深度反转，现在的背面变成了正面。两个方向会自发地交替；有时看到一个，有时看到另一个，但绝不会同时看到两者。“当我们稳定地观看图片或几何图形时，眼睛视网膜接收到的信息相对恒定，而大脑感知的信息通常不会改变。如果我们看到的图形恰好是一个模糊的图形，那么大脑感知到的图形可能会迅速改变，而从眼睛接收到的信息却不会发生任何变化。心理学家对这些知觉的变化感兴趣，并不是出于好奇，而是因为它们可以告诉我们有关知觉系统本质的信息。 大脑的职责就是代表外部世界。感知不仅仅是感觉，而是感官输入对表象系统的影响。模糊的图形为观看者提供了有两种或多种可能表示的输入
Pictures and geometric figures that spontancously change in appear ance have a peculiar fascination. A classic example is the line drawing of a transparent cube on this page.\\Then you first look at the cube, one of its faces seems to be at the front and the other at the back. Then if you look steadily at the drawing for a while, it will suddenly reverse in depth and what was the back face now is the front one. The two ori entations will alternate spontaneously; sometimes one is seen, sometimes the other, but never both at once.'When we look steadily at a picture or a geometric figure, the information re ceived by the retina of the eye is rela tively constant and what the brain per ceives usually does not change. If the figure we are viewing happens to be an ambiguous figure, what the brain per ceives may change swiftly without any change in the message it is receiving from the eye. The psychologist is inter ested in these perceptual alternations not as a curiosity but for what they can tell us about the nature of the percep tual system.It is the business of the brain to rep resent the outside world. Perceiving is not just sensing but rather an effect of sensory input on the representational system. An ambiguous figure provides the viewer with an input for which there are two or more possible representations
