The Extended Mind: The Power of Thinking Outside the Brain

by Annie Murphy Paul

we can choose to reappraise debilitating “stress” as productive “coping.” A 2010 study carried out with Boston-area undergraduates looked at what happens when people facing a stressful experience are informed about the positive effects of stress on our thinking—that is, the way it can make us more alert and more motivated. Before taking the GRE, the admissions exam for graduate school, one group of students was given the following message to read: “People think that feeling anxious while taking a standardized test will make them do poorly on the test. However, recent research suggests that arousal doesn’t hurt performance on these tests and can even help performance. People who feel anxious during a test might actually do better. This means that you shouldn’t feel concerned if you do feel anxious while taking today’s GRE test. If you find yourself feeling anxious, simply remind yourself that your arousal could be helping you do well.” A second group received no such message before taking the exam. Three months later, when the students’ GRE scores were released, the students who had been encouraged to reappraise their feelings of stress scored an average of 65 points higher.
