If not for the work of his half cousin Francis Galton, Charles Darwin's evolutionary theory might have met a somewhat different fate. In particular, with no direct evidence of natural selection and no convincing theory of heredity to explain it, Darwin needed a mathematical explanation of variability and heredity. Galton's work in biometry—the application of statistical methods to the biological sciences—laid the foundations for precisely that. This book offers readers a compelling portrait of Galton as the "father of biometry," tracing the development of his ideas and his accomplishments, and placing them in their scientific context. Though Michael Bulmer introduces readers to the curious facts of Galton's life—as an explorer, as a polymath and member of the Victorian intellectual aristocracy, and as a proponent of eugenics—his chief concern is with Galton's pioneering studies of heredity, in the course of which he invented the statistical tools of regression and correlation. Bulmer describes Galton's early ambitions and experiments—his investigations of problems of evolutionary importance (such as the evolution of gregariousness and the function of sex), and his movement from the development of a physiological theory to a purely statistical theory of heredity, based on the properties of the normal distribution. This work, culminating in the law of ancestral heredity, also put Galton at the heart of the bitter conflict between the "ancestrians" and the "Mendelians" after the rediscovery of Mendelism in 1900. A graceful writer and an expert biometrician, Bulmer details the eventual triumph of biometrical methods in the history of quantitative genetics based on Mendelian principles, which underpins our understanding of evolution today. -- A. W. F. Edwards, University of Cambridge, author of Pascal's Arithmetic Triangle and Likelihood

Race, while drawn from the visual cues of human diversity, is an idea with a measurable past, an identifiable present, and an uncertain future. The concept of race has been at the center of both triumphs and tragedies in American history and has had a profound effect on the human experience. Race Unmasked revisits the origins of commonly held beliefs about the scientific nature of racial differences, examines the roots of the modern idea of race, and explains why race continues to generate controversy as a tool of classification even in our genomic age. Surveying the work of some of the twentieth century's most notable scientists, Race Unmasked reveals how genetics and related biological disciplines formed and preserved ideas of race and, at times, racism. A gripping history of science and scientists, Race Unmasked elucidates the limitations of a racial worldview and throws the contours of our current and evolving understanding of human diversity into sharp relief.

Educational psychology is a broad field characterized by the study of individuals in educational settings and how they develop and learn. It incorporates information from such sub-disciplines such as developmental psychology, human development across the life span, curriculum and instruction, motivation, and measurement and assessment. Neil Salkind has mined the rich and extensive backlist of SAGE education and psychology journals to pull together a collection of almost 100 articles to be the definitive research resource on education psychology. Section One: Human Growth and Development focuses on the processes involved in human growth and development including ages and stages of development, different theoretical perspectives and the role and effectiveness of early intervention among other topics. Section Two: Cognition, Learning and Instruction concentrates on the mechanisms, through which individuals learn and retain information. Section Three: Motivation explores why individuals seek out goals and what the mechanisms are that characterize this search as it relates to learning. Section Four: Measurement, Assessment and Statistics looks at the topics that are critical to understanding individual differences, the growth in the use of computers as assessment tools, qualitative and quantitative methods, statistical techniques and evaluation.

Thirty years ago, it was estimated that less than five percent of the population had an anxiety disorder. Today, some estimates are over fifty percent, a tenfold increase. Is this dramatic rise evidence of a real medical epidemic? In All We Have to Fear, Allan Horwitz and Jerome Wakefield argue that psychiatry itself has largely generated this "epidemic" by inflating many natural fears into psychiatric disorders, leading to the over-diagnosis of anxiety disorders and the over-prescription of anxiety-reducing drugs. American psychiatry currently identifies disordered anxiety as irrational anxiety disproportionate to a real threat. Horwitz and Wakefield argue, to the contrary, that it can be a perfectly normal part of our nature to fear things that are not at all dangerous--from heights to negative judgments by others to scenes that remind us of past threats (as in some forms of PTSD). Indeed, this book argues strongly against the tendency to call any distressing condition a "mental disorder." To counter this trend, the authors provide an innovative and nuanced way to distinguish between anxiety conditions that are psychiatric disorders and likely require medical treatment and those that are not--the latter including anxieties that seem irrational but are the natural products of evolution. The authors show that many commonly diagnosed "irrational" fears--such as a fear of snakes, strangers, or social evaluation--have evolved over time in response to situations that posed serious risks to humans in the past, but are no longer dangerous today. Drawing on a wide range of disciplines including psychiatry, evolutionary psychology, sociology, anthropology, and history, the book illuminates the nature of anxiety in America, making a major contribution to our understanding of mental health.
