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.

Download or read book Twin Study written by Stacey Richter and published by Catapult. This book was released on 2008-05-28 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the sense that all stories have been written before, a truly startling piece of fiction may be the greatest literary feat possible. Enter Stacey Richter, a virtuoso contender for that very prize, whose offbeat characters manage to toe the line between eccentricity and banal daily life. Each story is organized around a pair of characters, and these characters are permitted to reach their full bizarre potential against mundane backdrops. The result is fiction that drives toward a place of surreal revelation, in these sometimes disturbing, often funny, short pieces. In Twin Study, Richter beautifully captures — albeit through unlikely exemplars — the essential experience of humanity.

Download or read book Methodology for Genetic Studies of Twins and Families written by M. Neale and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: Few would dispute the truth of the statement `People are Different', but there is much controversy over why. This book authoritatively explains the methods used to understand human variation, and extends them far beyond the primary `nature or nurture' question. After chapters on basic statistics, biometrical genetics, matrix algebra and path analysis, there is a state-of-the-art account of how to fit genetic models using the LISREL package. The authors explain not only the assumptions of the twin method, but how to test them. The elementary model is expanded to cover sex limitation, sibling interaction, multivariate and longitudinal data, observer ratings, and twin-family studies. Throughout, the methods are illustrated by applications to diverse areas such as obesity, major depression, alcohol comsumption, delinquency, allergies, and common fears.

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
