At the University of Kansas art museum, investigators tested the effects of different

colored walls on two groups of visitors to an exhibit of paintings. (在堪萨斯大学的艺术博物馆，研究者将来参观油画展览的人分成两组，测试不同颜色的墙对人的影响。)For the first group the room was painted white; for the second, the room was painted dark brown. Movement of each group was followed by an electrical system under the carpet. Investigators made careful observations and analyzed the data gathered and compared the differences between the two groups. The experiment revealed that those who entered the dark brown room walk more quickly, covered more area, and spent less time in the room than the people in the white environment. So the conclusion can be reached like this: dark brown stimulate more activity, but the activity ended sooner.

Not only the choice of colors but also the general appearance of a room communicates and influences those inside. Another experiment presented subjects(受试者) with photographs of faces that were to be rated in terms of energy and well-being. Three groups of subjects were used; each was shown the same photos, but each group was in a different kind of room. One group was in an "ugly" room that resembled a messy storeroom. Another group was in an average room-a nice office. The third group was in a tastefully designed living room with carpets and curtains. Results showed that the subjects in the beautiful room tended to give higher ratings to the faces than did those in the ugly room. Other studies suggest that students do better on tests taken in comfortable, attractive rooms than in ordinary-looking or ugly rooms.
