A well-known experiment used in organizational behavior courses involves showing the class an ambiguous picture--one that can be interpreted in two different ways. One such picture represents either an attractive young girl or an ugly old woman, depending on the way you look at it. Some of my colleagues and I use the experiment, which demonstrates how different people in the same situation may perceive quite different things. We start by asking half of the class to close their eyes while we show the other half a slightly altered version of the picture-one in which only the young girl can be seen-for only five seconds. Then we ask those who just saw the young girl's picture to close their eyes while we give the other half of the class a five-second look at a version in which only the old woman can be seen. After this preparation we show the ambiguous picture to everyone at the same time.
