Professor of psychology and neuroscience Charan Ranganath discusses memory's powerful role in decision-making, trauma processing, and self-understanding. The conversation explores the intertwining of memory and imagination, the impact of sensory triggers on nostalgia, the significance of elders in preserving cultural traditions, the mysteries of sleep in memory consolidation, and the concept of memory optimization for shaping the present and future.
Memory is not just a repository of the past, but an active force shaping our present and influencing our decisions.
Understanding memory mechanisms helps us understand ourselves better, leverage this knowledge for our benefit, and enhance our memory retention and decision-making skills.

The Transformative Power of Memory
Memory plays a crucial role in every aspect of our lives, influencing our ability to recall information, make decisions, and even heal from trauma. Recent scientific research highlights memory not just as a repository of the past, but as an active force shaping our present. Understanding memory mechanisms is key to understanding ourselves, our motivations, and leveraging this knowledge for our benefit.
Memory's Adaptive Nature
Memory storage and retrieval processes are constantly changing, impacting our self-perception and decision-making. Memory is selective, meaningful, and flexible, allowing us to focus on what truly matters. By grasping how memory operates, we can enhance our recall abilities, leading to improved memory retention and decision-making.
Episodic Memory and Human Uniqueness
Humans possess episodic memory, a unique form enabling us to recollect specific events tied to a particular time and place. Unlike other memories, episodic memory captures personal experiences that shape our identities and understanding of the world. This distinct memory type enriches our cognitive abilities and interactions.
Memory, AI, and Information Processing
While computers excel in storing vast amounts of data meticulously, human memory operates efficiently with limited information. Our brains utilize memory to construct a cohesive understanding of the world, blending perception and past experiences. Human memory's ability to prioritize informative moments over excessive data sets it apart from artificial intelligence's data-driven approach.
Professor of psychology and neuroscience Charan Ranganath visits Google to discuss his book "Why We Remember: Unlocking Memory's Power to Hold on to What Matters." The book reveals the powerful role memory plays in nearly every aspect of our lives, from recalling faces and names, to learning, decision-making, trauma, and healing.
A new understanding of memory is emerging from the latest scientific research. Memory is not quite the repository of the past that we can tap into as we wish. It is actually a highly transformative power, active at all times, that shapes our present in often secretive and sometimes destructive ways.
We are in many ways creatures of memory and only when we understand the mechanisms of memory can we truly understand ourselves and our motivations, and use our knowledge of those mechanisms to our advantage while avoiding their pitfalls. Why We Remember teaches the principles behind memory storage and retrieval, and explains how our memories are always changing. It reveals how these processes affect what we think we know about ourselves and how we make decisions.
Memory is designed to be selective, meaningful, and malleable. When we understand how memory works, we can cut through the clutter and remember the things we want to remember. We can not only remember more—we can remember better.
