Have you been staring cow-eyed at a computer all morning? Fiddling with your iPhone in line at Starbucks? Checking Twitter and ESPN every four minutes on your tablet?
Good. Here’s a little quiz. What one word ties these three ideas together: water + tobacco + stove? How about widow + bite + monkey? Or, envy + golf + beans?
Psychologists call such wordplay the “remote associates test,” or RAT, and use it to study creativity and intuition. The idea is that it requires a nimble, open mind to find the connection between seemingly unrelated ideas—in this case pipe, spider, and green.
But not all minds think alike, or even like a think. New research suggests that stepping away from the shiny Apple product and into the woods can have a big impact on creativity and problem-solving. Little is known about the human brain on technology—less than even the brain on drugs—but many social psychologists fear that so much “screen time” is rewiring our neural circuitry, and not for the better.
David Strayer, a professor of cognition and neural science at the University of Utah, noticed that his brain felt more limber, his thoughts more fluid, on backcountry trips in the Southwest than they did in the lab. His undergraduates reported a similar mental boost, as did his colleagues. The peripatetic life seemed ideal for thinking about thinking.
Strayer began to organize yearly camping trips for his fellow neuroscientists. In 2010, Ruth Ann and Paul Atchley, a wife-and-husband team of psychologists from the University of Kansas, joined him on a weeklong trek through Utah’s Grand Gulch. Ruth Ann asked the group to complete the RAT before hitting the trail, and again a few days into the 32-mile hike. “It worked really, really well,” Strayer says. “We had about a 45 percent improvement. So we said, ‘This seems to be perfect. It’s cheap, and it produces a nice big effect.’ ”
