We hear people talk about how addicted they are to their phones, videogames or the Internet. As it turns out, they might be right. A study done by the University of Maryland found that many college students experience symptoms of withdrawal if forced to go without media for a mere 24 hours. Researchers examined students from 10 countries, including the United States, Mexico, China, Argentina and Great Britain. They found that students from all these countries were susceptible to withdrawal symptoms (which include feelings of isolation, boredom and confusion), but folks from the United States and China were the most susceptible with 23 and 22 percent of students respectively reporting signs of addiction. That may be deceptive: Nearly a quarter of the Argentinean students dropped out of the study before the 24 hours were up—presumably because they couldn’t tolerate a day without their iPhones.
