Research Work
Although parrots have long been known for their capacities in vocal mimicry, Pepperberg set out to show that their vocal behavior could have the characteristics of human language. She worked intensively with a single African Grey Parrot, Alex, and reported that he acquired a large vocabulary and used it in a sophisticated way, which is often described as similar to that of a two-year old child. Pepperberg and her colleagues have sought to show that Alex can differentiate meaning and syntax, so that his use of vocal communication is unlike the relatively inflexible forms of "instinctive" communication that are widespread in the animal kingdom. Although such results are always likely to be controversial, and working intensively with a single animal always incurs the risk of Clever Hans effects, Pepperberg's work has strengthened the argument that humans do not hold the monopoly on the complex or semicomplex use of abstract communication.
Some researchers believe that the training method that Pepperberg used with Alex, (called the model-rival technique) holds promise for teaching autistic and other learning-disabled children who have difficulty learning language, numerical concepts and empathy. When some autistic children were taught using the same methods Dr. Pepperberg devised to teach parrots, their response exceeded expectations.
From work with the single subject Alex, Pepperberg and her colleagues have gone on to study additional African Grey Parrots, and also parrots of other species. A final evaluation of the importance of her work will probably depend on the success of these attempts to generalise it to other individuals.
Alex the African Grey Parrot was found dead on morning of September 6, 2007, and was seemingly healthy the previous day. On September 10, 2007, the necropsy of Alex revealed no discernible cause of death.

Famous quotes containing the words research and/or work:
“The great question that has never been answered, and which I have not yet been able to answer, despite my thirty years of research into the feminine soul, is “What does a woman want?” [Was will das Weib?]”
—Sigmund Freud (1856–1939)
“Since ... six weeks ago, there has been no day in which I have not had letters and visits on the subject of my nomination for the Presidency.... I say very little. I have in no instance encouraged any one to work to that end.... I have said the whole talk about me is on the score of availability. Let availability do the work then.”
—Rutherford Birchard Hayes (1822–1893)
