"The researchers then conducted a similar experiment with another set of people. Rather than taking walks between the rounds of testing, these subjects simply looked at photographs of either calm rural scenes or busy urban ones. The results were the same. The people who looked at pictures of nature scenes were able to exert substantially stronger control over their attention, while those who looked at city scenes showed no improvement in their attentiveness. “In sum,” concluded the researchers, “simple and brief interactions with nature can produce marked increases in cognitive control.” Spending time in the natural world seems to be of “vital importance” to “effective cognitive functioning.”
It is interesting to note that besides going to Nature areas, having pictures of nature scenes in our environment can help us calm our minds and have stronger control over our attention. Recently, I decided to paste a photo of Nature scenery in my bedroom wall, and I would look at the picture of green vegetation and I find that it helps to soothe my eyes and calm my mind.
