Bird Brains
The
Alex Studies:
Cognitive and Communicative Abilities
of Grey Parrots
by Irene Maxine Pepperberg, PhD
Charles T. Snowdon, University of Wisconsin, Madison writes: "Pepperberg has elegantly summarized her 20 years of success showing that an African Grey Parrot can match the cognitive and communicative competence of great apes. Her training paradigm involving reference, functionality and social interaction permits the expression of abilities hitherto unexpected in birds and challenges traditional views of the evolution of intelligence."
Marian Dawkins, University of Oxford writes: "Irene Pepperberg’s studies of Alex are some of the most remarkable and significant in the whole field of animal cognition. Her evidence stands up to the closest scrutiny, and Alex the parrot turns out to have cognitive abilities that were not even suspected before Pepperberg began her work."
