2、rs, but conform to their groups preferred techniques for performing them-a hallmark of human culture.Observers have previously reported that wild chimps demonstrate more than three dozen different behaviors that have no apparent ecological or genetic origin. This diversity suggests that there are di

3、stinct ape cultures.The notion assumes that chimps transmit culture-teaching and learning behaviors generation after generation. But the theory is very difficult to test and prove in a controlled experiment outside of a laboratory.So researchers at the University of St. Andrews in Scotland and Emory

4、 University in Atlanta devised an experiment to test the proposition. The results were published online August 21 in the science journal Nature.Learning and TeachingThe scientists constructed a box in which a desirable food was hidden behind a trap. Captive chimps could release the food by using a s

5、tick to move the trap in either of two ways. Researchers dubbed these the “poke“ and “lift“ methods.Scientists then isolated a high-ranking female of one group from her companions and taught her the poke method to release food. A female of high rank from a second group was taught the lift method.Non

6、e of the other members of the groups were allowed to watch the training.Finally, researchers used a third group as a control, presenting them with the box and sticks, but teaching them nothing about how to use them.Scientists then let the chimp groups watch their matriarch (女家长) use the technique sh

7、e had learned. To get the food, each dominant female consistently used the method she had been taught. The other chimps watched, often intensely, for over 36 hours spread over ten days.During this period, 15 chimps in the two study groups successfully used one method or the other to get food, and th

8、ey picked up the behavior quickly. Median times for learning the techniques in both groups were under a minute.In the meantime, the six chimps in the control group were stymied. In more than four hours of manipulating the sticks, they were unable to extract a single piece of food.Some chimps in the

9、“lift“ group discovered the poke method, and some in the “poke“ culture discovered lifting. But they were a small minority. When the apparatus was reintroduced two months later, the chimps reverted to their own cultures preferred method.This, the researchers maintain, provides evidence of a “conform

10、ist bias“. The animals discount their own experience and instead adopt the behavior of the group, just as humans do.“This is a very nice experimental setup,“ said Diana Reiss, a research scientist with the Bronx, New York-based Wildlife Conservation Society, who was not involved in the study. “It wa

11、s controlled for biases, and included a control group where there was no trained expert. The setup eliminated the problem of learning by interacting with humans.“The researchers believe they have demonstrated for the first time an ability among chimpanzees to transmit alternative technologies and al

12、ternative methods of using tools.Monkey See, Monkey Do“When all these different wild chimp behaviors were discovered in the field, there was controversy.“ said Frans de Waal, a professor of primate behavior at Emory University and study co-author. “Some scientists claimed it was social learning. Oth

13、ers claimed there were other possible explanations-individual learning, genetic differences, ecological variables, and so on.“We did the experiment to prove that you could plant a behavior by training one chimp and see it spread to other chimps by observation.“Giving the chimps two alternative metho

14、ds of accomplishing the same task, the researchers say, shows that chimps are capable of adopting local variants ( 变形) of a technique, just as they would if the variant behaviors seen in the wild are in fact socially transmitted.Not all experts agree with this conclusion. Rob Boyd, a professor of an

15、thropology at the University of California, Los Angeles, said, “I have argued that any time true imitation evolves, so will a tendency to copy the majority. So I would very much like it to be true that the data supported this prediction.“But Boyd believes the study data fail to offer the necessary p

16、roof. He notes that while a few chimps dropped their groups rarer behavioral variant (using a stick to poke or lift a trap to release food), the study “does not show that they switched to the common variant, which is what I believe is necessary.“Personifying AnimalsGroups of chimps at the Yerkes Nat

17、ional Primate Research Center Field Station at Emery University, where the research was carried out, have developed cultural differences on their own, without the intervention of human teachers.One community, for example, practices hand-clasp grooming (梳理毛发), in which two chimps each grasp one of th

18、e others hands over their heads, grooming with the free hand. Other groups do not engage in this behavior.Research with animal behavior, and perhaps especially with the great apes, risks wrongly attributing human characteristics to animals. But the researchers in this experiment say they have been c

19、areful to avoid that trap.“We aim to avoid naive anthropomorphism,“ said the lead author on the paper, Andrew Whiten of the University of St. Andrews, “by developing a rigorous experimental design that can unambiguously answer the question we pose.“He adds that the results were scored objectively fr

20、om videotapes viewed by other scientists to avoid bias. Whitten and his colleagues plan to do similar experiments with human children as subjects.“If we see similar responses in the two species.“ whiten said, “then a concern of interpretive anthropomorphism becomes rather contrived./（分数：70.00）(1).So

Few words in the English language have such a special meaning. Home is a place where you can relax, kick back a

43、nd just be yourself. Just about everyone has a strong opinion of what makes a house a home. And for most people in America, home should be, above all, comfortable.Americans like their homes to reflect their personal tastes. Many do-it-yourselfers enjoy fixing up their house and making it more “livab

44、le.“ They often try to create a cozy atmosphere so that when theyre at home, theyll really feel “at home.“ Sofas and lounge chairs may be heavily padded and arranged in groupings conducive ( 有益于 ) to relaxed conversation. The bathroom even receives special attention. Carpeted floors, scented soaps,

45、colorful wallpaper and decorative curtains adorn the “comfort room“ in many homes. And on average, Americans have more bathrooms than any other people in the world.Americans try to make the most of their space, too. The majority of homes have built-in closets and shelves, and people spare no pains t

46、o add dressers, filing cabinets and closet organizers to maximize their storage space. Although keeping the house neat is often a constant battle, Americans feel its a battle worth fighting.People in America keep an eye on the latest trends in interior design. In the 80s, the “country“ look dominate

47、d the home decorating scene. Rustic furniture and shelves full of old-fashioned knick-knacks created a homey atmosphere reminiscent of rural America several generations back. The 90s have brought in another longing for the past: the retro ( 怀旧的 ) 50s and 60s lookplain and simple furniture with square backs and arms and block-style legs.With all this attention to their homes, you would think Americans place a high premium on housekeeping. In fact, however, keeping house doesnt receive as much attention as it used to.
