The article discusses the evolving understanding of animal intelligence, particularly through the case of Alex, an African gray parrot trained by psychologist Eileen Pepperberg. Initially viewed as just another pet, Alex’s remarkable cognitive abilities became apparent over 31 years. His training utilized model/rival techniques, leading him to ask complex questions and understand concepts like color, counting, and material properties.
In 1980, Alex demonstrated potential self-awareness by asking about his reflection in the mirror. Despite skepticism from some scientists regarding the depth of his intelligence, others, like Dr. Donald Griffin, acknowledged that Alex’s abilities suggested a level of consciousness previously thought impossible for animals.
Alex passed away unexpectedly in 2007, leaving behind a legacy that continues to challenge notions of animal cognition. Another parrot, Apollo, has since set a record for identifying objects, furthering the discussion on animal intelligence.
