We all like routines, as they are familiar and comforting. That also translates into seat selection in a classroom. Pschologists have found that students often pick a seat in a classroom and sit in that same seat position all year. It actually helps them learn better.  This behavior is called �encoding specificity� and it �shows that people remember the context of how things were when we learned them�. Switching seats may not mean a bad test score for a student, but why tempt fate?
