    No new cells. No major changes. If you grew up depressed, angry, sad, aggressive, or nasty, you'd be that way for life. And, as you grew older, there'd be nowhere to go but down, as disease, age, or injury wiped out precious, irreplaceable brain cells. But over the past five, ten, twenty years, all that's changed. Using fMRI and PET scanning technology, neuroscientists can now look deep inside the human brain and they've discovered that it's amazingly flexible, resilient, and plastic. Pictures of the Mind: What the New Neuroscience Tells Us About Who We Are shows you what they've discovered and what it means to all of us. Through author Miriam Boleyn-Fitzgerald's masterfully written narrative and use stunning imagery, you'll watch human brains healing, growing, and adapting to challenges. You'll gain powerful new insights into the interplay between environment and genetics, begin understanding how people can influence their own intellectual abilities and emotional makeup, and understand the latest stunning discoveries about coma and "locked-in" syndrome. You'll learn about the tantalizing discoveries that may lead to cures for traumatic brain injury, stroke, emotional disorders, PTSD, drug addiction, chronic pain, maybe even Alzheimer's. Boleyn-Fitzgerald shows how these discoveries are transforming our very understanding of the "self," from an essentially static entity to one that can learn and change throughout life and even master the art of happiness.

    As sociologist and network science pioneer Duncan Watts explains in this provocative book, the explanations that we give for the outcomes that we observe in life—explanation that seem obvious once we know the answer—are less useful than they seem.Drawing on the latest scientific research, along with a wealth of historical and contemporary examples, Watts shows how common sense reasoning and history conspire to mislead us into believing that we understand more about the world of human behavior than we do; and in turn, why attempts to predict, manage, or manipulate social and economic systems so often go awry.It seems obvious, for example, that people respond to incentives; yet policy makers and managers alike frequently fail to anticipate how people will respond to the incentives they create. Social trends often seem to have been driven by certain influential people; yet marketers have been unable to identify these “influencers” in advance. And although successful products or companies always seem in retrospect to have succeeded because of their unique qualities, predicting the qualities of the next hit product or hot company is notoriously difficult even for experienced professionals.Only by understanding how and when common sense fails, Watts argues, can we improve how we plan for the future, as well as understand the present—an argument that has important implications in politics, business, and marketing, as well as in science and everyday life.

Ask anyone who has achieved their biggest goals or who thrives in their relationships, and you’ll hear stories of many unexpected detours along the way. What separates those who rise to these challenges and those who get derailed? The answer is agility—emotional agility.Emotional agility is a four-step approach that allows us to navigate life’s twists and turns with self-acceptance, clear-sightedness, and an open mind. In her more than twenty years of research, Susan David has found that no matter how intelligent, resilient, or creative people are, when they ignore how situations or interactions make them feel, they miss opportunities to gain insight, getting hooked by thoughts, emotions, and habits that prevent them from reaching their full potential. Emotionally agile people experience the same stresses and setbacks as anyone else, but they know how to adapt, aligning their actions with their values and making small changes that lead to a life of growth.Drawing on her extensive professional research, her international consulting work, and her own experiences growing up in Apartheid-era South Africa and losing her father at a young age, David shows how anyone can become more emotionally agile and thrive in an uncertain world. Written with authority, wit, and empathy, Emotional Agility will help you live your most successful life, whoever you are and whatever you face.
