The Differences Between The Sexes

In most animals, from bees to bison, house flies to humans, it is possible to see at a glance whether an individual is male or female. How and why have these differences in appearance and behaviour developed and what are the nature and extent of the differences between men and women? This book reviews the latest molecular, genetic, hormonal, anatomical and behavioural data in a wide range of species in a series of lively and highly readable articles from the world's leading experts in this field. Such an overview has never before been attempted. It will have a wide appeal, especially to undergraduates and graduates in the biological and medical sciences, and will help to bridge the gap between those who study genes and molecules in the laboratory and those who study the behaviour of animals in the wild.

It's obvious why only men develop prostate cancer and why only women get ovarian cancer. But it is not obvious why women are more likely to recover language ability after a stroke than men or why women are more apt to develop autoimmune diseases such as lupus. Sex differences in health throughout the lifespan have been documented. Exploring the Biological Contributions to Human Health begins to snap the pieces of the puzzle into place so that this knowledge can be used to improve health for both sexes. From behavior and cognition to metabolism and response to chemicals and infectious organisms, this book explores the health impact of sex (being male or female, according to reproductive organs and chromosomes) and gender (one's sense of self as male or female in society). Exploring the Biological Contributions to Human Health discusses basic biochemical differences in the cells of males and females and health variability between the sexes from conception throughout life. The book identifies key research needs and opportunities and addresses barriers to research. Exploring the Biological Contributions to Human Health will be important to health policy makers, basic, applied, and clinical researchers, educators, providers, and journalists-while being very accessible to interested lay readers.

Go beyond the headlines and the hype to get the newest findings in the burgeoning field of gender studies. Drawing on disciplines that include evolutionary science, anthropology, animal behavior, neuroscience, psychology, and endocrinology, Deborah Blum explores matters ranging from the link between immunology and sex to male/female gossip styles. The results are intriguing, startling, and often very amusing. For instance, did you know that. . . • Male testosterone levels drop in happy marriages; scientists speculate that women may use monogamy to control male behavior • Young female children who are in day-care are apt to be more secure than those kept at home; young male children less so • Anthropologists classify Western societies as "mildly polygamous" The Los Angeles Times has called Sex on the Brain "superbly crafted science writing, graced by unusual compassion, wit, and intelligence, that forms an important addition to the literature of gender studies."

Most contemporary discussions of sex differences assume that they are determined by society rather than biology. It is society that teaches little girls to be feminine and little boys to be masculine--society that tells women to respond to babies and men to respond to sports. Reflecting the fashionable idea that male and female roles have been "socially constructed," most commentators speak of gender instead of sex. Because men and women are virtually interchangeable, so the argument goes, men should do an equal share of domestic and childrearing work so that women can compete equally outside the home There's only one problem with this beguiling vision of androgyny. Whatever we might like to believe, as Dr. Steven Rhoads shows, sex distinctions remain a deeply rooted part of human nature. In "Taking Sex Differences Seriously," Rhoads assembles a wealth of scientific evidence showing that these differences are "hardwired" into our biology. They range from the subtle (men get a chemical high from winning while women get one from nursing) to the profound (women with high testosterone levels are more promiscuous, more competitive, and more conflicted about having children than those with average levels.) Rhoads explores disparities in aggression and dominance, in sexuality and nurturing. He shows how denial of these differences has helped to create the sexual revolution, fatherless families, and policies such as Title IX, and the call for universal day care. But while insisting that we must take sex differences seriously, Rhoads also advocates discouraging some natural tendencies, like men's desire for irresponsible sex, and encouraging others, like women's greater interest and talent in caring for babies. In this provocative exploration of the masculine and feminine, Steven Rhoads dispels contemporary clichéeacute;s and spotlights biological realities. Meticulously researched and elegantly written, "Taking Sex Differences Seriously" is a groundbreaking look at the way we are.

“[Fine’s] sharp tongue is tempered with humor. . . . Read this book and see how complex and fascinating the whole issue is.”—The New York Times It’s the twenty-first century, and although we tried to rear unisex children—boys who play with dolls and girls who like trucks—we failed. Even though the glass ceiling is cracked, most women stay comfortably beneath it. And everywhere we hear about vitally important “hardwired” differences between male and female brains. The neuroscience that we read about in magazines, newspaper articles, books, and sometimes even scientific journals increasingly tells a tale of two brains, and the result is more often than not a validation of the status quo. Women, it seems, are just too intuitive for math; men too focused for housework. Drawing on the latest research in neuroscience and psychology, Cordelia Fine debunks the myth of hardwired differences between men’s and women’s brains, unraveling the evidence behind such claims as men’s brains aren’t wired for empathy and women’s brains aren’t made to fix cars. She then goes one step further, offering a very different explanation of the dissimilarities between men’s and women’s behavior. Instead of a “male brain” and a “female brain,” Fine gives us a glimpse of plastic, mutable minds that are continuously influenced by cultural assumptions about gender. Passionately argued and unfailingly astute, Delusions of Gender provides us with a much-needed corrective to the belief that men’s and women’s brains are intrinsically different—a belief that, as Fine shows with insight and humor, all too often works to the detriment of ourselves and our society.

"The extent to which there are differences between the sexes is an area of interest to physiologists, neuroscientists, and clinicians, as well as social scientists and the general public. This book examines recent research on the biological basis of sex differences, including differences in the brain, behavior, the immune system, and disease states"--

Are boys and girls really that different? Twenty years ago, doctors and researchers didn’t think so. Back then, most experts believed that differences in how girls and boys behave are mainly due to differences in how they were treated by their parents, teachers, and friends. It's hard to cling to that belief today. An avalanche of research over the past twenty years has shown that sex differences are more significant and profound than anybody guessed. Sex differences are real, biologically programmed, and important to how children are raised, disciplined, and educated. In Why Gender Matters, psychologist and family physician Dr. Leonard Sax leads parents through the mystifying world of gender differences by explaining the biologically different ways in which children think, feel, and act. He addresses a host of issues, including discipline, learning, risk taking, aggression, sex, and drugs, and shows how boys and girls react in predictable ways to different situations. For example, girls are born with more sensitive hearing than boys, and those differences increase as kids grow up. So when a grown man speaks to a girl in what he thinks is a normal voice, she may hear it as yelling. Conversely, boys who appear to be inattentive in class may just be sitting too far away to hear the teacher—especially if the teacher is female. Likewise, negative emotions are seated in an ancient structure of the brain called the amygdala. Girls develop an early connection between this area and the cerebral cortex, enabling them to talk about their feelings. In boys these links develop later. So if you ask a troubled adolescent boy to tell you what his feelings are, he often literally cannot say. Dr. Sax offers fresh approaches to disciplining children, as well as gender-specific ways to help girls and boys avoid drugs and early sexual activity. He wants parents to understand and work with hardwired differences in children, but he also encourages them to push beyond gender-based stereotypes. A leading proponent of single-sex education, Dr. Sax points out specific instances where keeping boys and girls separate in the classroom has yielded striking educational, social, and interpersonal benefits. Despite the view of many educators and experts on child-rearing that sex differences should be ignored or overcome, parents and teachers would do better to recognize, understand, and make use of the biological differences that make a girl a girl, and a boy a boy.

In the third edition of her popular text, Sex Differences in Cognitive Abilities, Diane Halpern tackles fundamental questions about the meaning of sex differences in cognition and why people are so afraid of the differences. She provides a comprehensive context for understanding the theories and research on this controversial topic. The author employs the psychobiosocial model of cognition to negotiate a cease fire on the nature-nurture wars and offers a more holistic and integrative conceptualization of the forces that make people unique. This new edition reflects the explosion of theories and research in the area over the past several years. New techniques for peering into the human brain have changed the nature of the questions being asked and the kinds of answers that can be expected. There have been surprising new findings on the influence of sex hormones on cognitive abilities across the life span, as well as an increasing number of studies examining how attention paid to category variables such as one's sex, race, or age affects unconscious and automatic cognitive processes. Written in a clear, engaging style, this new edition takes a refreshing look at the science and politics of cognitive sex differences. Although it is a comprehensive and up-to-date synthesis of scientific theory and research into how, why, when, and to what extent females and males differ in intellectual abilities, it conveys complex ideas and interrelationships among variables in an engrossing and understandable manner, bridging the gap between sensationalized 'pop' literature and highly technical scientific journals. Halpern's thought-provoking perspectives on this controversial topic will be of interest to students and professionals alike.
