A scientific study at the University of New Mexico has found that players picked up a video game faster with a 9-volt battery strapped to their heads. No, really. [via]
Last year a succession of volunteers sat down in a research lab in Albuquerque, New Mexico to play DARWARS Ambush!, a video game designed to train US soldiers bound for Iraq. Each person surveyed virtual landscapes strewn with dilapidated buildings and abandoned cars for signs of trouble — a shadow cast by a rooftop sniper, or an improvised explosive device behind a rubbish bin. With just seconds to react before a blast or shots rang out, most forgot about the wet sponge affixed to their right temple that was delivering a faint electric tickle. The volunteers received a few milliamps of current at most, and the simple gadget used to deliver it was powered by a 9-volt battery.
