Timely and authoritative, this unique handbook explores the breadth of current knowledge on temperament, from foundational theory and research to clinical applications. Leaders in the field examine basic temperament traits, assessment methods, and what brain imaging and molecular genetics reveal about temperament's biological underpinnings. The book considers the pivotal role of temperament in parent–child interactions, attachment, peer relationships, and the development of adolescent and adult personality and psychopathology. Innovative psychological and educational interventions that take temperament into account are reviewed. Integrative in scope, the volume features extensive cross-referencing among chapters and a forward-looking summary chapter.

For the past twenty years Keirsey has continued to investigate personality differences, to refine his theory of the four temperaments and to define the facets of character that distinguish one from another. His findings form the basis of Please Understand Me II, an updated and greatly expanded edition of the book, far more comprehensive and coherent than the original, and yet with much of the same easy accessibility. One major addition is Keirsey's view of how the temperaments differ in the intelligent roles they are most likely to develop. Each of us, he says, has four kinds of intelligence, tactical, logistical, diplomatic, strategic, though one of the four interests us far more than the others, and thus gets far more practice than the rest. Like four suits in a hand of cards, we each have a long suit and a short suit in what interests us and what we do well, and fortunate indeed are those whose work matches their skills. As in the original book, Please Understand Me II begins with The Keirsey Temperament Sorter, the most used personality inventory in the world. But also included is The Keirsey Four-Types Sorter, a new short questionnaire that identifies one's basic temperament and then ranks one's second, third, and fourth choices. Share this new sorter with friends and family, and get set for a lively and fascinating discussion of personal styles.

We have seen these children—the shy and the sociable, the cautious and the daring—and wondered what makes one avoid new experience and another avidly pursue it. At the crux of the issue surrounding the contribution of nature to development is the study that Jerome Kagan and his colleagues have been conducting for more than two decades. In The Long Shadow of Temperament, Kagan and Nancy Snidman summarize the results of this unique inquiry into human temperaments, one of the best-known longitudinal studies in developmental psychology. These results reveal how deeply certain fundamental temperamental biases can be preserved over development. Identifying two extreme temperamental types—inhibited and uninhibited in childhood, and high-reactive and low-reactive in very young babies—Kagan and his colleagues returned to these children as adolescents. Surprisingly, one of the temperaments revealed in infancy predicted a cautious, fearful personality in early childhood and a dour mood in adolescence. The other bias predicted a bold childhood personality and an exuberant, sanguine mood in adolescence. These personalities were matched by different biological properties. In a masterly summary of their wide-ranging exploration, Kagan and Snidman conclude that these two temperaments are the result of inherited biologies probably rooted in the differential excitability of particular brain structures. Though the authors appreciate that temperamental tendencies can be modified by experience, this compelling work—an empirical and conceptual tour-de-force—shows how long the shadow of temperament is cast over psychological development.

Temperament is the first monograph in 40 years to present theories and basic findings in the field of temperament from a broad international and interdisciplinary perspective. The text, based on the author's four decades of personal study and data collection, thoroughly explores the physiological, biochemical, and genetic bases of temperament - incorporating age-specific methods of assessment developed through child- and adult-oriented approaches. The 147 illustrations comprise tables of the most popular temperament inventories for both children and adults, and unique data tables illustrating the psychometric features of temperament inventories based on self-rating and rating by others.

UNDERSTANDING YOUR CHILD'S TEMPERAMENT From their earliest days some children are shy and others are bold. A brother may be flexible, while his sister is rigid. One child is highly active, another far less so. One may stick with a challenge for hours, while another gives up easily. All children display distinct profiles of nine largely inborn temperament traits that determine how they experience their environments and respond to them. These interactions have a major impact on children's physical health, development, social behavior, and school performance, and on the caregivers themselves. If adults learn to recognize and tolerate temperament traits, they will be able to manage them more harmoniously and care for each child's individual needs. "What an important book for parents to consider. Treating each child as an individual shows them the respect that will engender self-esteem in them later. This book about differences in temperament by Dr. William Carey, an esteemed pediatrician, will give parents the backup they need to treat each child individually." T. Berry Brazelton, M.D Emeritus Professor of Pediatrics, Harvard Medical School Author of numerous books on child development and care. "America's favorite pediatrician" "This classic work is now more useful than ever. The too often neglected role of temperamental patterns is explained brilliantly, so that all adults who live or work with kids can understand and manage these all-important differences between them." Mel Levine, M.D. Professor of Pediatrics, University of North Carolina Medical School. Author of national bestseller, A Mind at a Time, and 10 other books about children's learning issues.

Integrating findings from recent literature and his ongoing 20-year research program, Watson (psychology, U. of Iowa) presents a framework for understanding short-term mood fluctuations and their relationship to differences in temperament and emotionality. He discusses the biological and environmental bases for mood fluctuations, relates affectivity to personality, links negative emotionality to various health complaints, and describes the implications of his study for theories of happiness.
