Our brains are noisy; certain regions insist on involuntary activities such as daydreaming, worrying about the future, or conversing with oneself. These activities occupy up to 47% of our waking time. While it can distract from the present and contribute to anxiety and depression, cognitive neuroscientist Moshe Bar reveals the potential benefit behind this apparent neurosis. Wandering is the first book to explore the multifaceted phenomenon of mind wandering and present the new research that underpins it. Bar combines decades of his research to explain the benefits and potential costs in the broader context of psychology, neuroscience, psychiatry, and philosophy, offering us practical and helpful insights.
