Each text book on spatial cognition informs about them: spatial compatibility effects. In a nutshell, they confirm the proverb that something fits like a pot on the lid. In a similar vein, spatial compatibility effects or their absence are used to explain major accidents involving man-made errors. But - are they really that relevant in daily life? They are mostly studied in the lab using simplified stimuli like simple geometrical shapes. In the research-oriented seminar we want to do exactly this: explore the role of spatial compatibility effects in daily objects or situations. Based on a self-selected problem, we want to empirically test whether responses are truely faster and less erroreous if they would follow the idea of spatial compatibility. So get ready and explore the role of spatial compatibility in your life!
