Alex's experiments

Alex's experiments, particularly with the African grey parrot named Alex, focused on understanding animal intelligence and communication. Over decades, researcher Irene Pepperberg taught Alex to identify colors, shapes, numbers, and even express concepts like "same" and "different." Alex's ability to use human-like speech and recognize objects demonstrated that animals could understand complex ideas, challenging the notion that language and cognitive abilities are unique to humans. His work has contributed to our understanding of animal cognition, highlighting the intelligence present in non-human species and prompting discussions about relationships between humans and animals.
