My guest is Dr. Jennifer Groh, PhD, professor of psychology and neuroscience at Duke University. She explains how our brain encodes sights and sounds and integrates them so we can navigate and understand the world around us. She explains what thoughts really are and how what you focus on determines your thoughts, not just in that moment but your future thoughts too. We discuss this in the context of how to improve your level of focus and happiness and how to complete tasks and task-switch more effectively. We also discuss how you can rewire the neural circuits that underlie your default patterns of thinking and attention.
