My guest on the Huberman Lab podcast out now is Dr. Alan Castel, PhD, professor of psychology at the University of California, Los Angeles (UCLA) and one of the world's foremost experts on human memory and cognitive aging. We discuss what science actually tells us about how to improve our learning ability and memory at any age. We also discuss how memory works, why all planning and imagination about the future are based on the past, false memories, and how to leverage curiosity, emotion, and self-testing retrieval practice to stamp in memories for the long term. We discuss what "superagers"—people who actually improve their cognitive capacity with age—do differently than everyone else. This episode is for anyone interested in the science of memory and tools to maintain and improve your memory across the lifespan.
