nvestigators were testing the effects of different colored walls on two groups of visitors to an exhibit of paintings. For the first group the room was painted white; for the second, dark brown. Movement of each group was followed by an electrical system under the carpet. The experiment revealed that those who entered the dark brown room walked more quickly, covered more area, and spend less time in the room than the people in the white environment. Dark brown stimulate more activity, but the activity ended sooner. Another experiment presented three groups of subjects with the same photographs, but each group was, in a different kind of room ---, an “ugly” room like a messy storeroom, an average room, such as a nice office, a tastefully living room with carpeting and curtains. Results showed that the subjects in the beautiful room tended to give higher ratings to the faces than did those in ugly room. Other studies suggest that students do better on tests taken in comfortable, attractive rooms than in ordinary-looking or ugly rooms. (1). What can be concluded from the two experiments? ( )
