walk in the woods





PSYCHOLOGY: A Walk in the Woods
Gilbert Chin

Spending time in the outdoors is commonly regarded as a wholesome approach to coping with the cacophony of contemporary developed societies. But does immersion in a natural environment lead to more than simply a sense of feeling refreshed--that is, might the metaphorical recharging of one's batteries be real? Berman et al. find that the less obtrusive sensory stimuli provided by a walk through an arboretum enabled people to perform better on a standard working memory task (backward digit span), in comparison to the stimuli of a stroll through a downtown landscape. Subsequent testing revealed a specific effect of scenic as opposed to urban settings on the executive portions (versus the alerting or orienting components) of an attentional network task, suggesting that a brief hiatus from focused application of attention allows for the replenishment and renewal of cognitive control centers. -- GJC
