Considerable evidence suggests that exposure to "green" environments can en
hance human effectiveness and make life's demands seem manageable. Does thi
s phenomenon extend to poor inner cities, where green space is minimal and
life's demands may be overwhelming? In 145 urban public housing residents r
andomly assigned to buildings with and without nearby nature, attentional f
unctioning and effectiveness in managing major life issues were compared. R
esidents living in buildings without nearby trees and grass reported more p
rocrastination in facing their major issues and assessed their issues as mo
re severe, less soluble, and more long-standing than did their counterparts
living in greener surroundings. Mediation tests and extensive tests for po
ssible confounds supported the attention restoration hypothesis-that green
space enhances residents' effectiveness by reducing mental fatigue. These f
indings suggest that urban public housing environments could be configured
to enhance residents' psychological resources for coping with poverty.
