Above is another example often used in social media or websites as a "dirty mind test." As in the previous example, there is a clear "correct" answer in this image and the mind typically works out the outline of the lamp within a few seconds. The high contrast between the lamp base and plastic cover, however, cause the eye to perceive the separation initially as the line between background and foreground, so the back wall is lumped together with the darker base until the image is more closely examined.
