全优冲刺100分系列答案The fact that blind people can see things using parts of their bodies apart from their eyes may help us to understand our feelings about color．If they can sense color differences, then perhaps we, too, are affected by color without knowing it．Salesmen have discovered by experience over a long period of time that sugar sells badly in green wrappings, that blue foods are considered not agreeable to the taste, and that cosmetics（化妆品） should never be packed in brown．These discoveries have grown into a whole subject of color psychology．
Some of our preferences are clearly psychological．Dark blue is the color of the night sky and therefore connected with calm, while yellow is a day color connected with energy and encouragement．Experiments have shown that colors, partly because they are connected with psychology, also have a direct effect on people's mind．People in bright red surroundings show an increase in breathing speed, heartbeat and blood pressure．Red is exciting．Pure blue has exactly the opposite effect; it is a calming color．Being exciting, red was chosen as the signal for danger, but a closer study shows that a bright yellow can produce a more basic state of alarm, so fire engines in some advanced areas are now rushing around in bright yellow colors that stop buses, trucks and cars．

Scientists at Harvard University and Bates College find female chimpanzees (黑猩猩) appear to treat sticks as dolls, carrying them around until they have children of their own. Young males engage in such behavior much less frequently.
The new work by Sonya M. Kahlenberg and Richard W. Wrangham, described this week in the journal Current Biology, provides the first evidence of a wild nonhuman species playing with dolls, as well as the first known sex difference in a wild animal’s choice of playthings.
The two researchers say their work adds to a growing body of evidence that human children are probably born with their own ideas of how they want to behave, rather than simply mirroring other girls who play with dolls and boys who play with trucks. Doll play among humans could have its origins in object—carrying by earlier apes (猿类), they say, suggesting that toy selection is probably not due entirely to socialization.
“In humans, there are obvious sex differences in children’s toy play, and these are remarkably similar across cultures,” says Kahlenberg. “While socialization by elders and peers has been the primary explanation, our work suggests that biology may also have an important role to play in activity preferences.”
In 14 years of data on chimpanzee behavior at the Kibale National Park in Uganda, Kahlenberg and Wrangham counted more than 100 examples of stickcarrying. Some young chimpanzees carried sticks into the nest to sleep with them and on one occasion built a separate nest for the stick. “We have seen juveniles occasionally carrying sticks for many years, and because they sometimes treated them rather like dolls, we wanted to know if in general this behavior tended to represent something like playing with dolls,” says Wrangham, a Professor at Harvard. “If the doll hypothesis (假设) was right, we thought that females should carry sticks more than males do, and that the chimpanzees should stop carrying sticks when they had their first child. We have now watched enough young chimpanzees to prove both points.”
