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.

Available in PDF, EPUB and Kindle. Book excerpt: The Trouble with Twin Studies questions popular genetic explanations of human behavioral differences based upon the existing body of twin research. Psychologist Jay Joseph outlines the fallacies of twin studies in the context of the ongoing decades-long failure to discover genes for human behavioral differences, including IQ, personality, and the major psychiatric disorders. This volume critically examines twin research, with a special emphasis on reared-apart twin studies, and incorporates new and updated perspectives, analyses, arguments, and evidence.

Download or read book Identical Strangers written by Paula Bernstein and published by Hachette UK. This book was released on 2012-03-01 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elyse Shein had always known she was adopted, but it wasn't until her mid-thirties that she searched for her biological mother. When Elyse contacted her adoption agency, she was not prepared for the shocking, life-changing news she received: she had an identical twin sister. Paula Bernstein, a married writer and mother living in New York, also knew she was adopted, but had no inclination to find her birth mother. When she answered a call from her adoption agency one spring afternoon, Paul's life suddenly divided into two starkly different periods: the time before and the time after she learned the truth. As they reunite and take their tentative first steps from strangers to sisters, Paul and Elyse learn that they were separated at birth as part of a secret study conducted by a pair of influential psychiatrists. They write with emotional honesty about the immediate intimacy they share as twins and the wide chasm that divides them as two complete strangers. Interweaving eye-opening studies and statistics on twin science into their story, IDENTICAL STRANGERS offers an intelligent and heartfelt glimpse into human nature. It is an account that broadens the definition of family and provides insight into our own DNA and the singularly exceptional imprint it leaves on our lives.

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.

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 Heritability of Intelligence written by Karl-Friedrich Fischbach and published by Springer Nature. This book was released on 2021-12-26 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: Is intelligence heritable? Karl-Friedrich Fischbach and Martin Niggeschmidt show that "heritability" means something different in biological terminology than in everyday language - which almost inevitably leads to misinterpretations. They explain why twin studies are controversial - and why genetic predictions of IQ and "educational attainment" must be treated with skepticism. This book is a translation of the original German 2nd edition Erblichkeit der Intelligenz by Karl-Friedrich Fischbach & Martin Niggeschmidt, published by Springer Fachmedien Wiesbaden GmbH, part of Springer Nature in 2019. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors. The Authors: Prof. Dr. Karl-Friedrich Fischbach is a developmental biologist and neurogeneticist. He was professor of biophysics and molecular biology at the University of Freiburg from 1985 to 2013, including two years as executive director of the Institute of Biology III. Martin Niggeschmidt is an editor in Hamburg.

Download or read book Waste written by William Viney and published by A&C Black. This book was released on 2014-05-22 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why are people so interested in what they and others throw away? This book shows how this interest in what we discard is far from new - it is integral to how we make, build and describe our lived environment. As this wide-ranging new study reveals, waste has been a polarizing topic for millennia and has been treated as a rich resource by artists, writers, philosophers and architects. Drawing on the works of Giorgio Agamben, T.S. Eliot, Jacques Derrida, Martin Heidegger, James Joyce, Bruno Latour and many others, Waste: A Philosophy of Things investigates the complexities of waste in sculpture, literature and architecture. It traces a new philosophy of things from the ancient to the modern and will be of interest to those working in cultural and literary studies, archaeology, architecture and continental philosophy.
