1、智课网TOEFL备考资料托福阅读机经背景文化类：猩猩的记忆方法 Infants and Apes Remember Things Similarly Infants and apes apparently adopt the same tactics(1) for remembering where things are, but as children develop their strategies change, a new study shows. The findings might reveal in part how the minds of our distant ancest
2、ors shifted gears(2) to embark(3) on the road toward humanity. There are two basic strategies animals use to remember where things are. Either they remember a things features, such as whether it was a banana, or they remember its place in space, such as left. All animals scientists have tested seem
3、to employ both strategies. However, if experiments are rigged(4) such that animals had to choose between the tactics, some species, such as chickens and toads(5), prefer a feature-based strategy. Others, such as fish and dogs, favor a place-based strategy. Researcher Daniel Haun at the Max Planck In
4、stitute for Evolutionary Anthropology in Leipzig, Germany and his colleagues investigated orangutans(6), gorillas(7), bonobos(8), chimpanzees(9) and humans. They wanted to see whether humanity and its closest relatives all adopted the same strategies for remembering where things are. Any changes in
5、strategy between species or within species would shed light on how they all evolved. At the Leipzig Zoo, the scientists hid rewards such as grapes, banana slices or toy animals under either a hollow piece of wood, an imitation(10) birds nest or an artificial hollow rock. At times, the rewards were c
6、oncealed(11) under the same object they were hidden beneath previously, whose place had changed. A feature-based strategy would best find these coveted items. At other times, the rewards were hidden at the same place they were concealed before, but under a different object. A place-based strategy wo
7、uld best discover these items. When human infants are a year old, they favor place-based strategies like all the other great ape species do. This suggests human and ape brains start out the same, at least when it comes to remembering where things are. The most recent common ancestors between humans
8、and all the other great apes date back to about 15 million years ago, suggesting this common preference has been part of our brain structures since at least then. However, three-year-old children preferred a feature-based strategy. The researchers noted this shift in strategy coincided with a period
