Could society's embrace of GPS be eroding our cognitive maps? Julia Frankenstein, a psychologist at the University of Freiburg's Center for Cognitive Science, says the danger of GPS is that "we are not forced to remember or process the information — as it is permanently 'at hand,' we need not think or decide for ourselves." "Next time you're in a new place, forget the GPS device. Study a map to get your bearings, then try to focus on your memory of it to find your way around. City maps do not tell you each step, but they provide a wealth of abstract survey knowledge. Fill in these memories with your own navigational experience, and give your brain the chance to live up to its abilities."
