Nowadays we feel that we have become dependent on our computers, mobile phones and other media, and that we need these things to think and act creatively. But a recent study seems to indicate that the best thing we might be able to do for our creativity is leave all of these high-tech (高科技) toys at home and just take a walk in the woods.

In the study, David L. Strayer and his fellow researchers worked with 30 men and 26 women who were about to go on a four-day hike, during which they would be taken away from all of the creative toys mentioned above. Before the hike began, Strayer gave the participants (参与者) a standardized Remote Associates Test, which is often used to test creativity and creative problem-solving abilities. After the hike, they were given the test again. The result showed that there was a 50% improvement in the participants’ creative problem-solving abilities. As Strayer says, “This is a great effect.”

This study is the first to document systematic changes in higher-level cognitive (认知的) function connected with entering nature. The researchers suggest that the effect nature seems to have on improving creative thinking is due to the lack of distractions (分心的事) in the natural environment — there are no ringing phones, noisy computers, etc. Other studies have shown that the colour green — the colour of much of nature — is felt by the brain as relaxing, and that increased relaxation may be one of the factors that improve creativity.

None of this is exactly news. The benefits of nature for the mind have been known for centuries. The philosopher and author Henry David Thoreau spoke eloquently (富于表现力地) about the two years he spent in the countryside. The experience certainly seemed to develop his creativity — he went on to write almost 50 books. Given this recent study, it looks as if his advice in Walden to “simplify, simplify, simplify” is good — if you want to relax your mind and make it become more creative, take a walk in the woods, and leave your cellphone behind.
