The Chimpanzee Metacognition Experiment

Explore groundbreaking research on chimpanzee cognition in this 44-minute interview with Professor Jan Engelmann from UC Berkeley. Discover how island-based experiments at Ngamba Island reveal that chimpanzees can rationally revise their beliefs when presented with new evidence, demonstrating a key feature of rational thought previously thought to be uniquely human. Learn about the methodology behind three pivotal experiments examining how chimpanzees respond to strong evidence versus counter-evidence, weak evidence scenarios, and evidence that undermines their initial assumptions. Delve into the broader implications of these findings for understanding the evolution of cognition and comparative psychology. Gain insights into Professor Engelmann's background in animal cognition research, his collaborative international research approach, and upcoming projects that continue to push the boundaries of our understanding of primate intelligence. The discussion covers the theoretical foundations of comparative psychology, the practical challenges of conducting field research with chimpanzees, and how these discoveries reshape our understanding of rational thinking across species.
