How to Improve Your Memory & Cognitive Function at Any Age | Dr. Alan Castel
Summary
Andrew Huberman interviews UCLA psychologist Dr. Alan Castel about the science of memory, emphasizing that learning improves through "errorful retrieval" rather than passive repetition. They discuss how memory is reconstructive, often influenced by emotion and metacognition, which can lead to confident but inaccurate eyewitness testimony. The episode also covers strategies for maintaining cognitive health across the lifespan, including the benefits of curiosity, novelty, and challenging oneself to combat age-related decline.
