“A landmark in our understanding of human development.”
—Paul Harris, author of Trusting What You’re Told

“Magisterial…Makes an impressive argument that most distinctly human traits are established early in childhood and that the general chronology in which these traits appear can…be identified.”
—Wall Street Journal

Virtually all theories of how humans have become such a distinctive species focus on evolution. Becoming Human looks instead to development and reveals how those things that make us unique are constructed during the first seven years of a child’s life.

In this groundbreaking work, Michael Tomasello draws from three decades of experimental research with chimpanzees, bonobos, and children to propose a new framework for psychological growth between birth and seven years of age. He identifies eight pathways that differentiate humans from their primate relatives: social cognition, communication, cultural learning, cooperative thinking, collaboration, prosociality, social norms, and moral identity. In each of these, great apes possess rudimentary abilities, but the maturation of humans’ evolved capacities for shared intentionality transform these abilities into uniquely human cognition and sociality.

“How does human psychological growth run in the first seven years, in particular how does it instill ‘culture’ in us? …Most of all, how does the capacity for shared intentionality and self-regulation evolve in people? This is a very thoughtful and also important book.”
—Tyler Cowen, Marginal Revolution

“Theoretically daring and experimentally ingenious, Becoming Human squarely tackles the abiding question of what makes us human.”
—Susan Gelman

“Destined to become a classic. Anyone who is interested in cognitive science, child development, human evolution, or comparative psychology should read this book.”
—Andrew Meltzoff

Proud, happy, grateful—gay youth describe their lives in terms that would have seemed surprising only a generation ago. Yet many adults, including parents, seem skeptical about this sea change in perceptions and attitudes. Even in an age of growing tolerance, coming out as gay is supposed to involve a crisis or struggle. This is the kind of thinking, say the young men at the heart of this book, that needs to change.

Becoming Who I Am is an astute exploration of identity and sexuality as told by today’s generation of gay young men. Through a series of in-depth interviews with teenagers and men in their early 20s, Ritch Savin-Williams reflects on how the life stories recorded here fulfill the promise of an affirmative, thriving gay identity outlined in his earlier book, The New Gay Teenager. He offers a contemporary perspective on gay lives viewed across key milestones: from dawning awareness of same-sex attraction to first sexual encounters; from the uncertainty and exhilaration of coming out to family and friends to the forming of adult romantic relationships; from insights into what it means to be gay today to musings on what the future may hold. The voices hail from diverse ethnic and socioeconomic backgrounds, but as gay men they share basic experiences in common, conveyed here with honesty, humor, and joy.

More than any other psychologist, Carol Gilligan has helped us to hear girls' voices just when they seem to be blurring and fading or becoming disruptive during the passage into womanhood. When adolescent girls--once assured and resilient--silence or censor themselves to maintain relationships, they often become depressed, and develop eating disorders or other psychological problems. But when adolescent girls remain outspoken it is often difficult for others to stay in relationship with them, leading girls to be excluded or labeled as troublemakers. If this is true in an affluent suburban setting, where much of the groundbreaking research took place, what of girls from poor and working-class families, what of fading womanhood amid issues of class and race? And how might these issues affect the researchers themselves? In Between Voice and Silence Taylor, Gilligan, and Sullivan grapple with these questions. The result is a deeper and richer appreciation of girls' development and women's psychological health.

In an urban public school, among girls from diverse cultural backgrounds--African American, Hispanic, Portuguese, and white--and poor and working-class families, the authors sought a key to the relationship between risk, resistance, and girls' psychological development and health. Specifically, they found cultural differences that affect girls' coming of age in this country. In Between Voice and Silence, the story of the study parallels another, that of African American, Hispanic, and white women who gathered to examine their own differences and to learn how to avoid perpetuating past divisions among women. Together, these two stories reveal an intergenerational struggle to develop relationships between and among women and to hold and respect difference.

The identical “Jim twins” were raised in separate families and met for the first time at age thirty-nine, only to discover that they both suffered tension headaches, bit their fingernails, smoked Salems, enjoyed woodworking, and vacationed on the same Florida beach. This example of the potential power of genetics captured widespread media attention in 1979 and inspired the Minnesota Study of Twins Reared Apart. This landmark investigation into the nature-nurture debate shook the scientific community by demonstrating, across a number of traits, that twins reared separately are as alike as those raised together.

As a postdoctoral fellow and then as assistant director of the Minnesota Study, Nancy L. Segal provides an eagerly anticipated overview of its scientific contributions and their effect on public consciousness. The study’s evidence of genetic influence on individual differences in traits such as personality (50%) and intelligence (70%) overturned conventional ideas about parenting and teaching. Treating children differently and nurturing their inherent talents suddenly seemed to be a fairer approach than treating them all the same. Findings of genetic influence on physiological characteristics such as cardiac and immunologic function have led to more targeted approaches to disease prevention and treatment. And indications of a stronger genetic influence on male than female homosexuality have furthered debate regarding sexual orientation.
