Sex, after hunger, may be the most powerful motivating force in our lives. It drives us to seek intimate contact with others and to form relationships that may be fleeting or lifelong, blissful or troubled. Yet many mysteries surround sex and sexuality: Why don’t we reproduce by virgin birth? Why does so much of our sexual behavior have nothing to do with reproduction? Why isn’t everyone heterosexual? How does the brain create sexual arousal? How do sexual kinks develop? Is porn harmful? W...

What causes a child to grow up gay or straight? Neuroscientist Simon LeVay summarizes a wealth of scientific evidence that points to one inescapable conclusion: Sexual orientation results primarily from an interaction between genes, sex hormones, and the cells of the developing body and brain. LeVay takes the reader on a whirlwind tour of laboratories that specialize in genetics, endocrinology, neuroscience, cognitive psychology, evolutionary psychology, and family demographics. He describ...

A compelling behind-the-scenes look at cutting-edge scientific inquiry, as well as a brilliant examination of the ramifications of genetic research, The Science of Desire is a lasting resource in the increasingly significant debate over the role that genetics plays in our lives.In July 1993, a scientific event made front-page news: the discovery that genetics plays a significant role in determining homosexuality. In The Science of Desire, Dean Ham...

This positive psychology textbook focuses on the importance of the body within optimal functioning and highlights new research in this area.

By carefully examining the biological, genetic, evolutionary, and psychological evidence, a noted biologist finds a shocking lack of substance behind ideas about biologically based sex differences. Features a new chapter and afterward on recent biological breakthroughs.

Because of rapidly aging populations, the number of people worldwide experiencing dementia is increasing and the projections are grim. Despite hundreds of millions of dollars invested in medical research, no effective treatment has been discovered for Alzheimer's disease, the most common form of dementia. The Alzheimer Conundrum exposes the predicaments embedded in current efforts to slow down or halt Alzheimer's disease through early detection of presymptomatic biological changes...

We remember the admonition of our mothers: “Treat others as you want them to treat you.” But what if being nice was something we were inclined by nature to do anyway? Renowned neuroscientist Donald Pfaff upends our entire understanding of ethics and social contracts with an intriguing proposition: the Golden Rule is hardwired into the human brain.Pfaff, the researcher who first discovered the connections between specific brain circuits and certain behaviors, contends that the basic...

Babies who cry a lot, or are unsettled in the night, are common sources of concern for parents and, consequently, costly problems for health services. In this book, Ian St James-Roberts summarises the evidence concerning infant crying and sleeping problems to provide a new evidence-based approach to these common challenges for parents and health services. The book begins by distinguishing between infant and parental parts of the problems and provides guidelines for assessing each issue.

How different are men and women, really? Controversy surrounds the question and makes uncovering the answers—based in evolution, genetics, and biology—increasingly difficult. Still, significant differences between the sexes are apparent everyday to both men and women. Whether it’s a boyfriend’s infidelity or a wife’s inability to orgasm during sex, the differences between the sexes affect how we act, interact, and think about one another. Developmental biologist Lewis Wolpert has devoted y...

The true role of biology in determining sexual orientation is an oft-debated issue in both the popular media and scientific communities, and evaluating the literature on the topic can be daunting. Nature’s Choice: What Science Reveals About the Biological Origins of Sexual Orientation offers both a comprehensive review of the scientific literature and a fresh perspective on this complex and politically charged subject. Respected researcher, speaker, and author Dr. Cheryl W...

What does it mean to find a gene or set of genes that are associated with ADHD, schizophrenia, or autism? Could we eradicate such diseases from our species through gene therapy? Is it possible to eradicate from our genome the genetic material that predisposes us to be too aggressive, too shy, less intelligent, or not active enough? Who has the political power and/or moral authority to make these decisions?The premise of Nature and Nurture is that the complexity of the tran...
