Abstract All current explanations of the Bourdon illusion imply that the illusion persists under mirror imaging over the vertical or horizontal axes. We tested this hypothesis in three experiments. For orientations of the standard Bourdon figure of about 135°, the illusion shows a dip, which is unexplainable in terms of current theories.
