Scientist noted for her studies in animal cognition
Irene Maxine Pepperberg (born April 1, 1949) is an American scientist noted for her studies in animal cognition, particularly in relation to parrots. She has been a professor, researcher and/or lecturer at multiple universities, and she is currently an Adjunct Research Professor at Boston University. Pepperberg also serves on the Advisory Council of METI (Messaging Extraterrestrial Intelligence). She is well known for her comparative studies into the cognitive fundamentals of language and communication, and she was one of the first to work on language learning in animals other than primate species (exemplified by the Washoe project), by extension to a bird species. Pepperberg is also active in wildlife conservation, especially in relation to parrots.

Born in 1949 as Irene Platzblatt in Brooklyn, New York City, New York, she was an only child. Her father, Robert Platzblatt, was a biochemist and middle school teacher. In the 1950s, the family resided in Brooklyn in an apartment above a store, and beginning at a very young age, Irene would own and train a series of budgies.

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 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 four year old child. Alex could understand labels to describe objects, colors, shapes, and materials. Pepperberg and her colleagues sought to show that Alex could differentiate meaning and syntax, so that his use of vocal communication was 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 semi complex use of abstract communication. With interspecies communication, Pepperberg speculated that grey parrots are comparable to primates, having similar social systems. that the training method that Pepperberg used with Alex, (called the model/rival technique) When some autistic children were taught using the same methods Pepperberg devised to teach parrots, their response exceeded expectations.

The model/rival technique involves two trainers, one to give instructions, and one to model correct and incorrect responses and to act as the student's rival for the trainer's attention; the model and trainer also exchange roles so that the student sees that the process is fully interactive. The parrot, in the role of student, tries to reproduce the correct behavior. The use of this model/rival technique resulted in Alex identifying objects by color, shape, number and material at about the level of chimpanzees and dolphins. His language abilities were equivalent to those of a 2 year old child and he had the problem solving skills of a 5 year old. Alex was learning the alphabet, had a vocabulary of 150 words, knew the names of 50 objects and could count up to eight when he died. He could also answer questions about objects. Pepperberg countered critics' claims that Alex had been taught a script by explaining that the controls and tests she used made it impossible for him simply to recite words when she asked questions. The Clever Hans effect did not apply, she argued, as Alex would talk to anyone, not just to her. Pepperberg's implementation of the model rival technique has been used to successfully train several other parrots, such as Apollo.

Pepperberg is president of The Alex Foundation, a not for profit 501(c)(3) organization, which she started. The foundation supports Pepperberg and her team's research. In a 2006 interview, Pepperberg said that the foundation was her only funding source, having lost her paid research position due to a funding crunch at MIT's Media Lab, although the reporter of that interview does not mention her research associate position at Harvard University since 2005.

Some researchers have suggested that studying avian cognition might allow a useful artificial intelligence to be built without requiring as much resources, as for some applications a parrot or corvid level complexity brain would be adequate such as for image sorting. In recent years it was found that pigeons could sort CT scan data as well as microscope slides with equal or better accuracy than a human expert with only weeks of behavioral training needed.

Pepperberg was married for more than twenty years to David Pepperberg, a neuroscientist.
