She was interested in learning if animals could think，and the best way to do this， she reasoned， was to talk to them. To test her theory，she bought an African gray parrot she named Alex and taught him to reproducethe sounds of the English language. "I thought if he learned to communicate， Icould ask him questions about how he sees the world，- she explains.
When Pepperberg began her research with Alex， very few scientistsackno wledged that animals were capable of thought. The beliefwas that animalsreacted to things in their environment but lacked the ability to think or feel.How， then， could a scientist demonstrate that animals might， in fact， possessintelligence? "That's why I started my studies with Alex，" Pepperberg says.
Certain skills are considered key signs of higher mental abilities： a good memory， an understanding of symbols， self-awareness， understanding of others' mmotives， and creativity. Little by little， researchers have documented these abilities in other species. Sheep and elephants can recognize faces. Chimpanzees - who are genetically similar to humans - use a variety of primitive tools for eating， drinking， and hunting; they also laugh when pleased and spit to show disgust with something. Octopuses in captivity are known to amuse themselves by shooting water at laboratory staff. They may even exhibit basic emotions by changing color.
Alex the parrot was a surprisingly good talker. He learned how to use his voice to imitate almost i00 English words， including those for foods， colors， shapes， and numbers. Although imitation was once considered a simple skill， in recent years cognitive scientists have revealed that it's extremely difficult. It requires the imitator to form a mental image of the other person's body and actions and then adjust his own body parts into the same position. It is a behavior that shows an awareness of one's self.
Because Alex had mastered many English words， Pepperberg could ask him questions about a bird's basic understanding of the world. Alex could count， as well as describe， shapes， colors， and sizes for Pepperberg; he even had a basic understanding of the abstract concept of zero.
Many of Alex's cognitive skills， such as his ability to understand the concepts of same and different， are generally attributed only to higher mammals， particularly primates （such as humans and apes）. But parrots， like great apes （and humans）， live a long time in complex societies. And like primates， these birds must monitor the changing relationships within the group.
