How Room Designs Affect Our Work and Feeling
Architects have long had the feeling that the place we live in can affect our thoughts, feeling and behaviors. But now scientists are giving this feeling an empirical（经验的，实证的）basis. They are discovering how to design spaces that promote creativity, keep people focused, and lead to relaxation.
Researches show that aspects of the physical environment can influence creativity. In 2009, Joan Meyers-Levy at the University of Minnesota, reported that the height of a room’s ceiling affects how people think. Her research indicates that higher ceilings encourage people to think more freely, which may lead them to make more abstract connections. Low ceilings, on the other hand, may inspire a more detailed outlook.
In addition to ceiling height, the view afforded by a building may influence an occupant’s ability to concentrate. Nancy Wells and her colleagues at Cornell University result of a family move made the most gains on a standard test of attention.
Using nature to improve focus of attention ought to pay off academically, and it seems to, according to a study led by C. Kenneth Tanner, head of the School Design & Planning Laboratory at the University of Georgia. Tanner and his team found that higher scores on tests of vocabulary, language arts and maths than did students whose classrooms primarily overlooked roads and parking lots.
Recent study on room lighting design suggests that dim（暗淡的）light helps people to loosen up. If that is true generally, keeping the light low during dinner, or at parties could increase relaxation. Researchers of Harvard Medical School also discovered that furniture with rounded edges could help visitors relax.
So far scientists have focused mainly on public buildings. “We have a very limited number of studies, so we are almost looking at the problem through a straw（吸管）” architect David  Allison says; “How do you take answers to very specific questions and make broad,generalize use of them?” That is what we are all struggling with”
