Renowned primatologist Robert Sapolsky offers a completely revised and updated edition of his most popular work, with over 225,000 copies in print Now in a third edition, Robert M. Sapolsky's acclaimed and successful Why Zebras Don't Get Ulcers features new chapters on how stress affects sleep and addiction, as well as new insights into anxiety and personality disorder and the impact of spirituality on managing stress. As Sapolsky explains, most of us do not lie awake at night worrying about whether we have leprosy or malaria. Instead, the diseases we fear-and the ones that plague us now-are illnesses brought on by the slow accumulation of damage, such as heart disease and cancer. When we worry or experience stress, our body turns on the same physiological responses that an animal's does, but we do not resolve conflict in the same way-through fighting or fleeing. Over time, this activation of a stress response makes us literally sick. Combining cutting-edge research with a healthy dose of good humor and practical advice, Why Zebras Don't Get Ulcers explains how prolonged stress causes or intensifies a range of physical and mental afflictions, including depression, ulcers, colitis, heart disease, and more. It also provides essential guidance to controlling our stress responses. This new edition promises to be the most comprehensive and engaging one yet.

Now updated with new material throughout, Alicia F. Lieberman’s The Emotional Life of the Toddler is the, detailed look into the varied and intense emotional life of children aged one to three. Anyone who has followed an active toddler around for a day knows that a child of this age is a whirlwind of explosive, contradictory, and ever-changing emotions. Alicia F. Lieberman offers an in-depth examination of toddlers’ emotional development and illuminates how to optimize this crucial stage so that toddlers can develop into emotionally healthy children and adults. Drawing on her lifelong research, Dr. Lieberman addresses commonly asked questions and issues. Why, for example, is “no” often the favorite response of the toddler? How should parents deal with the anger they might feel when their toddler is being aggressively stubborn? Why does a crying toddler run to his mother for a hug only to push himself vigorously away as soon as she begins to embrace him? This updated edition also addresses 21st-century concerns such as how to handle screen time on devices and parenting in a post-internet world. Hailed as “groundbreaking” by The Boston Globe after its initial publication, the new edition includes the latest research on this crucial stage of development. With the help of numerous examples and vivid cases, Lieberman answers these and other questions, providing, in the process, a rich, insightful profile of the roller coaster emotional world of the toddler.
