Wenderoth's (1978) comments on my paper (Hartley, 1978) contain a serious oversight that taints the interpretation offered. Briefly, I showed observers dots placed within a square or an incomplete square on a piece of paper. They were asked to reproduce the position of the dot on a second, blank piece of paper. Glossing over details, the finding was that the reproduced position was displaced from the veridical position toward the location ofthe surrounding lines. There was no displacement toward axes of bilateral symmetry, that is, major axes.
