Nature May Nurture Creativity
Backpackers scored 50 percent better on a creativity test after spending four days in nature disconnected from electronic devices, according to a new study.
“This is a way of showing that interacting with nature has real, measurable benefits to creative problem-solving that really hadn’t been formally demonstrated before,” said David Strayer, Ph.D., a co-author of the study and professor of psychology at the University of Utah. “It provides a rationale for trying to understand what is a healthy way to interact in the world, and that burying yourself in front of a computer 24/7 may have costs that can be remediated by taking a hike in nature.”
The study involved 56 people — 30 men and 26 women — with an average age of 28 who participated in four- to six-day wilderness hiking trips organized by the Outward Bound expedition school in Alaska, Colorado, Maine and Washington State. No electronic devices were allowed on the trips.
Of those 56 subjects, 24 took a 10-item creativity test the morning before they began their backpacking trip, and 32 took the test on the morning of the trip’s fourth day.
Researchers report that people who had been backpacking four days got an average of 6.08 of the 10 questions correct, compared with an average score of 4.14 for people who had not yet begun the trip.
“We show that four days of immersion in nature, and the corresponding disconnection from multimedia and technology, increases performance on a creativity, problem-solving task by a full 50 percent,” the researchers conclude.
The researchers point out that the study was not designed to “determine if the effects are due to an increased exposure to nature, a decreased exposure to technology or the combined influence of these two factors.”
While earlier research has indicated nature has beneficial effects, “it’s equally plausible that it is not multitasking to wits’ end that is associated with the benefits,” Strayer said.
The researchers cited earlier studies indicating that children spend only 15 to 25 minutes daily in outdoor play and sports, and that the average 8- to 18-year-old spends more than 7.5 hours a day using media such as TV, cell phones and computers.
They also cited earlier work on “attentional restoration theory,” which says that modern technology and multitasking place demands on our “executive attention” — the ability to switch among tasks, stay on task and inhibit distracting actions and thoughts — and that nature is effective in replenishing these abilities.
“Our modern society is filled with sudden events — sirens, horns, ringing phones, alarms, television, etc. — that hijack attention,” the researchers wrote in the study, which was published in PLoS ONE, an online journal published by the Public Library of Science. “By contrast, natural environments are associated with gentle, soft fascination, allowing the executive attentional system to replenish.”
Earlier research showed that going on a hike can improve proofreading, the ability to see a certain optical illusion, and the ability to repeat digits backwards after hearing a list of digits. But Strayer noted that none of those abilities provide a standard measure of executive attention or creativity.
So he and fellow researchers Ruth Ann Atchley and Paul Atchley from the University of Kansas did a trial run for the study by trying a variety of creativity tests on themselves during a five-day backpacking trip in southern Utah’s Grand Gulch in May 2010.
They decided to use a test known as the Remote Associates Test, or RAT, that is a standard measuring tool for creative thinking and problem-solving. These abilities are believed to arise in the same prefrontal cortex area of the brain that is overtaxed by constant demands on our attention in our technological environment, the researchers note.
In the untimed test, participants get 10 sets of three words. For each set they must come up with a fourth word that is tied to the other three. For example, an answer to SAME/TENNIS/HEAD might be MATCH (because a match is the same, tennis match and match head).
Unlike other studies, where subjects were tested in labs after brief periods outdoors, “the current study is unique in that participants were exposed to nature over a sustained period and they were still in that natural setting during testing,” the researchers said.
