Mysterious preferences in stereo perception

In a very simple stereo configuration, we discovered that observers exhibit strong biases. When an upper dot is presented in front of a lower dot, the depth between the dots is perceived as completely different from the depth between an upper dot behind a lower dot. We have shown that the bias cannot be explained by cyclovergence biases or the tilt of the horopter.
