Available in PDF, EPUB and Kindle. Book excerpt: The identical “Jim twins” were raised in separate families and met for the first time at age thirty-nine, only to discover that they both suffered tension headaches, bit their fingernails, smoked Salems, enjoyed woodworking, and vacationed on the same Florida beach. This example of the potential power of genetics captured widespread media attention in 1979 and inspired the Minnesota Study of Twins Reared Apart. This landmark investigation into the nature-nurture debate shook the scientific community by demonstrating, across a number of traits, that twins reared separately are as alike as those raised together. As a postdoctoral fellow and then as assistant director of the Minnesota Study, Nancy L. Segal provides an eagerly anticipated overview of its scientific contributions and their effect on public consciousness. The study’s evidence of genetic influence on individual differences in traits such as personality (50%) and intelligence (70%) overturned conventional ideas about parenting and teaching. Treating children differently and nurturing their inherent talents suddenly seemed to be a fairer approach than treating them all the same. Findings of genetic influence on physiological characteristics such as cardiac and immunologic function have led to more targeted approaches to disease prevention and treatment. And indications of a stronger genetic influence on male than female homosexuality have furthered debate regarding sexual orientation.

Book Synopsis Accidental Brothers by : Dr. Nancy L. Segal
Download or read book Accidental Brothers written by Dr. Nancy L. Segal and published by St. Martin's Press. This book was released on 2018-04-17 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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; and William and Wilber, who were raised in the remote rural village of La Paz, 150 miles away. Their parents and siblings were aware of the enormous physical and behavioral differences between the members of each set, but never doubted that the two belonged in their biological families. Everyone’s life unraveled when one of the twins—William—was mistaken by a young woman for his real identical twin, Jorge. Her “discovery” led to the truth—that the alleged twins were not twins at all, but rather unrelated individuals who ended up with the wrong families. Blending great science and human interest, Accidental Brothers by Nancy L. Segal and Yesika S. Montoya will inform and entertain anyone interested in how twin studies illuminate the origins of human behavior, as well as mother-infant identification and the chance events that can have profound consequences on our lives.
Book Synopsis Deliberately Divided by : Nancy L. Segal
Download or read book Deliberately Divided written by Nancy L. Segal and published by Rowman & Littlefield. This book was released on 2021-11-08 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 a twin—the study’s investigators insisted that the separation be kept secret. Here, Nancy Segal reveals the inside stories of the agency that separated the twins, and the collaborating psychiatrists who, along with their cadre of colleagues, observed the twins until they turned twelve. This study, far outside the mainstream of scientific twin research, was not widely known to scholars or the general public until it caught the attention of documentary filmmakers whose recent films, Three Identical Strangers and The Twinning Reaction,left viewers shocked, angered, saddened and wanting to know more. Interviews with colleagues, friends and family members of the agency’s psychiatric consultant and the study’s principal investigator, as well as a former agency administrator, research assistants, journalists, ethicists, attorneys, and—most importantly--the twins and their families who were unwitting participants in this controversial study, are riveting. Through records, letters and other documents, Segal further discloses the investigators’ attempts to engage other agencies in separating twins, their efforts to avoid media exposure, their worries over informed consent issues in the 1970s and the steps taken toward avoiding lawsuits while hoping to enjoy the fruits of publication. Segal's spellbinding stories of the twins’ separation, loss and reunion offers readers the behind-the-scenes details that, until now, have been lost to the archives of history.

Book excerpt: A New York Times Notable Book for 1998 Critical acclaim for Lawrence Wright's A Rhone-Poulenc Science Prize Finalist "This is a book about far more than twins: it is about what twins can tell us about ourselves."—The New York Times "With plenty of amazing stories about the similarities and differences of twins, Wright respectfully shows, too, how their special circumstance in life challenges our notions of individuality. A truly fascinating but sometimes spooky (Mengele's experiments with twins at Auschwitz figure among Wright's examples) study."—American Library Association "Like so much of Wright's work, this book is a pleasure to read. Because he writes so well, without pushing a particular point of view, he soon has you pondering questions you have tended to comfortably ignore."—Austin American-Statesman "Informative and entertaining . . . a provocative subject well considered by a talented journalist."—Kirkus Reviews

Book Synopsis Working and Growing Up in America by : Jeylan T. MORTIMER
Download or read book Working and Growing Up in America written by Jeylan T. MORTIMER and published by Harvard University Press. This book was released on 2009-06-30 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Should teenagers have jobs while they're in high school? Doesn't working distract them from schoolwork, cause long-term problem behaviors, and precipitate a precocious transition to adulthood? This report from a remarkable longitudinal study of 1,000 students, followed from the beginning of high school through their mid-twenties, answers, resoundingly, no. Examining a broad range of teenagers, Jeylan Mortimer concludes that high school students who work even as much as half-time are in fact better off in many ways than students who don't have jobs at all. Having part-time jobs can increase confidence and time management skills, promote vocational exploration, and enhance subsequent academic success. The wider social circle of adults they meet through their jobs can also buffer strains at home, and some of what young people learn on the job--not least responsibility and confidence--gives them an advantage in later work life.
Book Synopsis Romania’s Abandoned Children by : Charles A. Nelson
Download or read book Romania’s Abandoned Children written by Charles A. Nelson and published by Harvard University Press. This book was released on 2014-01-06 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: The implications of early experience for children's brain development, behavior, and psychological functioning have long absorbed caregivers, researchers, and clinicians. The 1989 fall of Romania's Ceausescu regime left approximately 170,000 children in 700 overcrowded, impoverished institutions across Romania, and prompted the most comprehensive study to date on the effects of institutionalization on children's well-being. Romania's Abandoned Children, the authoritative account of this landmark study, documents the devastating toll paid by children who are deprived of responsive care, social interaction, stimulation, and psychological comfort. Launched in 2000, the Bucharest Early Intervention Project (BEIP) was a rigorously controlled investigation of foster care as an alternative to institutionalization. Researchers included 136 abandoned infants and toddlers in the study and randomly assigned half of them to foster care created specifically for the project. The other half stayed in Romanian institutions, where conditions remained substandard. Over a twelve-year span, both groups were assessed for physical growth, cognitive functioning, brain development, and social behavior. Data from a third group of children raised by their birth families were collected for comparison. The study found that the institutionalized children were severely impaired in IQ and manifested a variety of social and emotional disorders, as well as changes in brain development. However, the earlier an institutionalized child was placed into foster care, the better the recovery. Combining scientific, historical, and personal narratives in a gripping, often heartbreaking, account, Romania's Abandoned Children highlights the urgency of efforts to help the millions of parentless children living in institutions throughout the world.

Download or read book Separated @ Birth written by Anais Bordier and published by Penguin. This book was released on 2015-09-01 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: THE STORY BEHIND THE FILM TWINSTERS One of the Top Ten Facebook Stories of the decade When twenty-five-year-old South Korean adoptee and actress Samantha Futerman opened a Facebook message from a stranger named Anaïs Bordier, she had no idea that it would change her life forever… Adopted from South Korea as an infant, Sam grew up in New Jersey with her parents and two brothers. She never imagined she had a sister; nor did Anaïs—who grew up in France and was also adopted from South Korea—until she saw an actress with a face identical to her own in a YouTube video and decided to contact her doppelgänger via social media. A few dubious exchanges turned from mistrust and cynicism to utter shock, as the women discovered more in common than just their looks—and their birth date. Samantha and Anaïs’s ensuing adventure is a dive into the fascinating research on identical twins, particularly those who have been separated since birth; a reexamination of nature vs. nurture; a guide through the often befuddling territory of foreign adoption; and an emotional soul-search for two inextricably connected set of parents and children. Their discovery can only be described as the unimaginable journey of a lifetime—one that spans languages, continents, cultures, and ultimately proves that none of these barriers can disrupt the unbreakable bond between sisters.
