In episode 2, we test Irene Pepperberg on animal cognition and symbolic communication. Dr. Pepperberg worked with Alex the African Grey Parrot for 30 years, until his untimely death, and continues to work with other African Greys (Athena and Griffin) to explore the limits of their congnitive abilities. Long story short: she still hasn’t reached the edge. The more we look, the more fascinating avian capabilities we find. Irene is an unconvential scientist in many ways, from her wrist bangles (which you’ll hear) to her background in theoretical chemistry (!), and she’s great at telling her story. Enjoy!
