We engage with our environment using our different senses. For instance, we can see the space around us and how we are positioned in the environment. If the ceiling is above us and the floor is below us we are probably standing. But what if the ceiling was where the wall should be? In this case, where would we think up is? Meaghan McManus works in the Perception and Action Lab at Justus Liebig University in Giessen, where she pursues her research interests in space perception. In her talk, she will draw on numerous examples to show that our sense of orientation and space is not always as correct as we think it is.
