"Ground surfaces allow the observers to utilize depth cues more effectively than ceiling surfaces and this information is preferably used for the perception of spatial layout (so-called ground dominance effect). What if the observers are confined to the interiors in which there is an abundance of ceiling information for a long time? We are investigating the susceptibility of six volunteers attending experiment simulating flight to Mars to the upright as well as upside-down corridor illusion. In the course of 520 days crew members are tested five times. Their task is to adjust the relative length of two lines presented on the background of photographic scene. Whereas the scene gives a strong 3D impression in the upright version, in the upside-down version the impression is rather flat. The data shows that after eight months, the subjects\u2019 susceptibility to the upside-down corridor illusion is already noticeably greater, which might indicate increased sensitivity to ceiling information."@en . . . .
