"Imagine renting a car in the United Kingdom. Though you may be an experienced driver on American soil, making the switch to the “wrong” side of the road can be a bit of a challenge. You have to remain vigilant and pay close attention to the new rules, as well as inhibit your automatic tendency to want to drive on the right. Chances are, you will also make a few mistakes at first or as you grow tired.Common wisdom holds that we learn best from our mistakes. But researchers at Michigan State University have published a new study that suggests something more is needed: We must be conscious of our mistakes to reap the benefits of improved performance."
