As infants we are rife with potential. For a short time, we have before us a seemingly infinite number of developmental paths. Soon, however, we become limited to certain paths as we grow into unique products of our genetics and experience. But what factors account for the variation -- in skills, personalities, values -- that results? How do experiences shape what we bring into the world? In The Human Spark, pioneering psychologist Jerome Kagan offers an unflinching examination of personal, moral, and cultural development that solidifies his place as one of the most influential psychologists of the past century. In this definitive analysis of the factors that shape the human mind, Kagan explores the tension between biology and the environment. He reviews major advances in the science of development over the past three decades and offers pointed critiques and new syntheses. In so doing, Kagan calls out the shortcomings of the modern fad for neuroscience, shows why theories of so-called attachment parenting are based on a misinterpretation of research, and questions the field's reflexive tendency to pathologize the behavior of the young. Most importantly, he reminds us that a life, however influenced by biology and upbringing, is still a tapestry to be woven, not an outcome to be endured. A profound exploration of what is universal and what is individual in human development, The Human Spark is the result of a scientist's lifelong quest to discover how we become who we are. Whether the reader is a first-time parent wondering what influence she, her genes, and the wider world will have on her child; an educator seeking insight into the development of her students; or simply a curious soul seeking self-knowledge, Kagan makes an expert and companionable guide.

Humans are unique among all other species in having one cognitive attribute-the ability, almost without conscious effort, to engage in blending. This is the first book that brings the theory of blending to a wide audience and shows how blending is at the heart of the origin of ideas.

"This is a wonderful book. Frances Ashcroft has a rare gift for making difficult subjects accessible and fascinating." —Bill Bryson, author of The Body: A Guide for Occupants What happens during a heart attack? Can someone really die of fright? What is death, anyway? How does electroshock treatment affect the brain? What is consciousness? The answers to these questions lie in the electrical signals constantly traveling through our bodies, driving our thoughts, our movements, and even the beating of our hearts. The history of how scientists discovered the role of electricity in the human body is a colorful one, filled with extraordinary personalities, fierce debates, and brilliant experiments. Moreover, present-day research on electricity and ion channels has created one of the most exciting fields in science, shedding light on conditions ranging from diabetes and allergies to cystic fibrosis, migraines, and male infertility. With inimitable wit and a clear, fresh voice, award-winning researcher Frances Ashcroft weaves together compelling real-life stories with the latest scientific findings, giving us a spectacular account of the body electric.

The association between our ancestors and fire, somewhere around six to four million years ago, had a tremendous impact on human evolution, transforming our earliest human ancestor, a being communicating without speech but with insight, reason, manual dexterity, highly developed social organization, and the capability of experimenting with this new technology. As it first associated with and then began to tame fire, this extraordinary being began to distance itself from its primate relatives, taking a path that would alter its environment, physiology, and self-image. Based on her extensive research with nonhuman primates, anthropologist Frances Burton details the stages of the conquest of fire and the systems it affected. Her study examines the natural occurrence of fire and describes the effects light has on human physiology. She constructs possible variations of our earliest human ancestor and its way of life, utilizing archaeological and anthropological evidence of the earliest human-controlled fires to explore the profound physical and biological impacts fire had on human evolution.

A bold new synthesis of paleontology, archaeology, genetics, and anthropology that overturns misconceptions about race, war and peace, and human nature itself, answering an age-old question: What made humans so exceptional among all the species on Earth? Creativity. It is the secret of what makes humans special, hiding in plain sight. Agustín Fuentes argues that your child's finger painting comes essentially from the same place as creativity in hunting and gathering millions of years ago, and throughout history in making war and peace, in intimate relationships, in shaping the planet, in our communities, and in all of art, religion, and even science. It requires imagination and collaboration. Every poet has her muse; every engineer, an architect; every politician, a constituency. The manner of the collaborations varies widely, but successful collaboration is inseparable from imagination, and it brought us everything from knives and hot meals to iPhones and interstellar spacecraft. Weaving fascinating stories of our ancient ancestors' creativity, Fuentes finds the patterns that match modern behavior in humans and animals. This key quality has propelled the evolutionary development of our bodies, minds, and cultures, both for good and for bad. It's not the drive to reproduce; nor competition for mates, or resources, or power; nor our propensity for caring for one another that have separated us out from all other creatures. As Fuentes concludes, to make something lasting and useful today you need to understand the nature of your collaboration with others, what imagination can and can't accomplish, and, finally, just how completely our creativity is responsible for the world we live in. Agustín Fuentes's resounding multimillion-year perspective will inspire readers—and spark all kinds of creativity.

How "Aha!" really happens. When do you get your best ideas? You probably answer "At night," or "In the shower," or "Stuck in traffic." You get a flash of insight. Things come together in your mind. You connect the dots. You say to yourself, "Aha! I see what to do." Brain science now reveals how these flashes of insight happen. It's a special form of intuition. We call it strategic intuition, because it gives you an idea for action-a strategy. Brain science tells us there are three kinds of intuition: ordinary, expert, and strategic. Ordinary intuition is just a feeling, a gut instinct. Expert intuition is snap judgments, when you instantly recognize something familiar, the way a tennis pro knows where the ball will go from the arc and speed of the opponent's racket. (Malcolm Gladwell wrote about this kind of intuition in Blink.) The third kind, strategic intuition, is not a vague feeling, like ordinary intuition. Strategic intuition is a clear thought. And it's not fast, like expert intuition. It's slow. That flash of insight you had last night might solve a problem that's been on your mind for a month. And it doesn't happen in familiar situations, like a tennis match. Strategic intuition works in new situations. That's when you need it most. Everyone knows you need creative thinking, or entrepreneurial thinking, or innovative thinking, or strategic thinking to succeed in the modern world. All these kinds of thinking happen through flashes of insight--strategic intuition. And now that we know how it works, you can learn to do it better. That's what this book is about. Over the past ten years, William Duggan has conducted pioneering research on strategic intuition and for the past three years has taught a popular course at Columbia Business School on the subject. He now gives us this eye-opening book that shows how strategic intuition lies at the heart of great achievements throughout human history: the scientific and computer revolutions, women's suffrage, the civil rights movement, modern art, microfinance in poor countries, and more. Considering the achievements of people and organizations, from Bill Gates to Google, Copernicus to Martin Luther King, Picasso to Patton, you'll never think the same way about strategy again. Three kinds of strategic ideas apply to human achievement: * Strategic analysis, where you study the situation you face * Strategic intuition, where you get a creative idea for what to do * Strategic planning, where you work out the details of how to do it. There is no shortage of books about strategic analysis and strategic planning. This new book by William Duggan is the first full treatment of strategic intuition. It's the missing piece of the strategy puzzle that makes essential reading for anyone interested in achieving more in any field of human endeavor.

A fresh look at electricity and its powerful role in life on Earth When we think of electricity, we likely imagine the energy humming inside our home appliances or lighting up our electronic devices—or perhaps we envision the lightning-streaked clouds of a stormy sky. But electricity is more than an external source of power, heat, or illumination. Life at its essence is nothing if not electrical. The story of how we came to understand electricity’s essential role in all life is rooted in our observations of its influences on the body—influences governed by the body’s central nervous system. Spark explains the science of electricity from this fresh, biological perspective. Through vivid tales of scientists and individuals—from Benjamin Franklin to Elon Musk—Timothy Jorgensen shows how our views of electricity and the nervous system evolved in tandem, and how progress in one area enabled advancements in the other. He explains how these developments have allowed us to understand—and replicate—the ways electricity enables the body’s essential functions of sight, hearing, touch, and movement itself. Throughout, Jorgensen examines our fascination with electricity and how it can help or harm us. He explores a broad range of topics and events, including the Nobel Prize–winning discoveries of the electron and neuron, the history of experimentation involving electricity’s effects on the body, and recent breakthroughs in the use of electricity to treat disease. Filled with gripping adventures in scientific exploration, Spark offers an indispensable look at electricity, how it works, and how it animates our lives from within and without.

Why our human brains are awesome, and how we left our cousins, the great apes, behind: a tale of neurons and calories, and cooking. Humans are awesome. Our brains are gigantic, seven times larger than they should be for the size of our bodies. The human brain uses 25% of all the energy the body requires each day. And it became enormous in a very short amount of time in evolution, allowing us to leave our cousins, the great apes, behind. So the human brain is special, right? Wrong, according to Suzana Herculano-Houzel. Humans have developed cognitive abilities that outstrip those of all other animals, but not because we are evolutionary outliers. The human brain was not singled out to become amazing in its own exclusive way, and it never stopped being a primate brain. If we are not an exception to the rules of evolution, then what is the source of the human advantage? Herculano-Houzel shows that it is not the size of our brain that matters but the fact that we have more neurons in the cerebral cortex than any other animal, thanks to our ancestors' invention, some 1.5 million years ago, of a more efficient way to obtain calories: cooking. Because we are primates, ingesting more calories in less time made possible the rapid acquisition of a huge number of neurons in the still fairly small cerebral cortex—the part of the brain responsible for finding patterns, reasoning, developing technology, and passing it on through culture. Herculano-Houzel shows us how she came to these conclusions—making “brain soup” to determine the number of neurons in the brain, for example, and bringing animal brains in a suitcase through customs. The Human Advantage is an engaging and original look at how we became remarkable without ever being special.
