【题目】Inside Animal Minds

Irene Pepperberg, a graduate of Harvard University, was interested in learning if animals could think. The best way to do this, she reasoned, was to talk to them. So she bought an African grey parrot she named Alex and taught him to reproduce the sounds of the English language. “I thought if he learned to communicate, I could ask him questions about how he sees the world.” She explains.

When Pepperberg began her research with Alex, very few scientists agreed that animals were able to think. How could a scientist prove that animals might, in fact, have intelligence (智力)? “That’s why I started my studies with Alex.” Pepperberg says.

Alex the parrot was a surprisingly good talker. He learned how to use his voice to imitate (模仿) almost 100 English words, including those for foods, colors, shapes and numbers. Although imitation was once considered a simple skill, in recent years, scientists have reported that it’s a very difficult ability. It requires the imitator to form an image of the other person’s body and actions in their mind and then put his own body parts into same place. It is a behavior that shows self-awareness (自我意识). Because Alex had mastered many English words, Pepperberg could ask him questions about a bird’s basic understanding of the world. Alex could count, describe shapes and colors; he even had a basic understanding of the idea of zero.

Many of Alex’s skills are normally only for humans and primates (灵长类). But parrots, live a long time in mixed societies. And like primates, these birds must watch the changing relationships within the group. This may explain Alex’s ability to learn a human language. Parrots learn to pronounce and use our words so they can become a part of our group.

Many researchers say that creativity and language in animals, like other forms of intelligence, have developed. “People were surprised to discover that some primates make tools,” says Alex Kacelnik, an animal researcher at Oxford University. “But people also thought, ‘Well, they share our ancestry (祖先) — of course they are smart.’ Now we are finding these kinds of behaviors in some birds. But we don’t have a recently shared ancestry with birds. It means,” Kacelnik continues, “intelligence is not something only for primates or humans.”
