A groundbreaking study of twins brings together the latest scientific research and case studies to explore the complexities of human behavior and development as it examines such topics as twins separated at birth, pseudotwins, the loss of a twin, the implications of new fertility drugs, and more. 10,000 first printing. Tour.
The Minnesota Study of Twins Reared Apart startled scientists by demonstrating that twins reared apart are as alike, across a number of personality traits and other measures, as those raised together, suggesting that genetic influence is pervasive. Segal offers an overview of the study’s scientific contributions and effect on public consciousness.
The combination of a riveting true story and cutting-edge twin research makes this book an irresistible page-turner. Identical twins Begoña and Delia were born thirty-eight years ago in Spain’s Canary Islands. Due to chaotic conditions at the hospital or simple human error, the unthinkable happened: Delia was unintentionally switched with another infant in the baby nursery. This fascinating story describes in vivid detail the consequences of this unintentional separation of identical twin sisters. The author considers not only the effects on these particular sisters, but the important implications of this and similar cases for questions concerning identity, familial bonds, nature-nurture, and the law.
Twin Mythconceptions: False Beliefs, Fables, and Facts about Twins sheds new light on over 70 commonly held ideas and beliefs about the origins and development of identical and fraternal twins. Using the latest scientific findings from psychology, psychiatry, biology, and education, the book separates fact from fiction. Each idea about twins is described, followed by both a short answer about the truth, and then a longer, more detailed explanation. Coverage includes embryology of twins, twin types, intellectual growth, personality traits, sexual orientation of twins, marital relationships, epigenetic analyses, and more. Five appendices cover selected topics in greater depth, such as the freq...
"A unique window into human behavior and development." —Steven Pinker The riveting story of two sets of identical twins separated at birth and improbably reunited as adults, a dream case for exploring nature and nurture. Accidental Brothers tells the unique story of two sets of identical Colombian twin brothers who discovered at age 25 that they were mistakenly raised as fraternal twins—when they were not even biological brothers. Due to an oversight that presumably occurred in the hospital nursery, one twin in each pair was switched with a twin in the other pair. The result was two sets of unrelated “fraternal” twins—Jorge and Carlos, who were raised in the lively city of Bogotá;...
Developmental and Fetal Origins of Differences in Monozygotic Twins: From Genetics to Environmental Factors examines the major causes of discordance in monozygotic twins, from genetic, to environmental influences, including discussions on the genetic, epigenetic, fetal and environmental factors. Twin differences discussed include malformations, deformations and disruptions secondary to inequitable division of the early embryo, chromosome and single gene mosaicism, Nonrandom X chromosome inactivation, mitochondrial heteroplasmy, epigenetic variation, and variable and inequitable blood supply, among other influences. Differences in hemoglobin levels, placentation and amniotic fluid are also examined, while full color images illustrate discordant anomalies and twin differences throughout. - Examines the major causes of discordance in monozygotic twins and their relevance for future studies and clinical management - Discusses NIPT in MZ twins, twin imaging during fetal development, blood tests and forensic analysis - Features contributions from international experts in twin genetics and developmental biology
Twin Research: Biology, Health, Epigenetics, and Psychology is a comprehensive, applied resource in twinning and twin studies that is grounded in the most impactful findings from twin research in recent years. While targeted to undergraduate and graduate students, this compendium will prove a valuable resource for scholars already familiar with twin studies, as well as those coming to the field for the first time. Here, more than forty experts across an array of disciplines examine twinning and twin research methodologies from the perspectives of biology, medicine, genetic and epigenetic influences, and neuroscience. Chapters provide clear instruction in both basic and advanced research meth...
Shyness is a common problem that comes with a high price. If you suffer from shyness or social anxiety you might avoid social situations and may have trouble connecting with others due to an extreme fear of humiliation, rejection, and judgment. As a shy person, you may also experience panic attacks that make it even more likely that you’ll avoid social situations. With The Mindfulness and Acceptance Workbook for Social Anxiety and Shyness, the authors’ acceptance and commitment therapy (ACT) program for overcoming shyness has become available to the public for the first time. This program has been found to be highly effective in research studies for the treatment of social anxiety disord...
This handbook provides research guidelines to study roles of the genes and other factors involved in a variety of complex behaviors. Utilizing methodologies and theories commonly used in behavior genetics, each chapter features an overview of the selected topic, current issues, as well as current and future research.
A 2022 Choice Reviews Outstanding Academic Title Takes the first in-depth look at the New York City adoption agency that separated twins and triplets in the 1960s, and the controversial and disturbing study that tracked the children’s development while never telling their adoptive parents that they were raising a “singleton twin.” In the early 1960s, the head of a prominent New York City Child Development Center and a psychiatrist from Columbia University launched a study designed to track the development of twins and triplets given up for adoption and raised by different families. The controversial and disturbing catch? None of the adoptive parents had been told that they were raising...
