Download or read book The Trouble with Twin Studies written by Jay Joseph and published by Routledge. This book was released on 2014-11-20 with total page 334 pages. 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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 methods, family and parenting aspects of twinning, twin studies as applied across various disease areas and medical specialties, genetic and epigenetic determinants of differentiation, and academic, neurological and cognitive development. The presentation of existing studies and methods instruction empowers students and researchers to apply twin-based research and advance new studies across a range of biomedical and behavioral fields, highlighting current research trends and future directions. Offers unique insights into twinning rates, mechanisms and factors surrounding twinship Provides clear instruction on both basic and advanced twin research methods and study design Features leading international experts in twin biology, genetics, health and psychology Examines findings from recent twin studies across a broad array of health and behavioral studies

Download or read book Born Together—Reared Apart written by Nancy L. Segal and published by Harvard University Press. This book was released on 2012-06-18 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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 The Oxford Handbook of Quantitative Methods, Vol. 2: Statistical Analysis written by Todd D. Little and published by Oxford University Press. This book was released on 2013-02-01 with total page 784 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research today demands the application of sophisticated and powerful research tools. Fulfilling this need, The Oxford Handbook of Quantitative Methods is the complete tool box to deliver the most valid and generalizable answers to todays complex research questions. It is a one-stop source for learning and reviewing current best-practices in quantitative methods as practiced in the social, behavioral, and educational sciences. Comprising two volumes, this handbook covers a wealth of topics related to quantitative research methods. It begins with essential philosophical and ethical issues related to science and quantitative research. It then addresses core measurement topics before delving into the design of studies. Principal issues related to modern estimation and mathematical modeling are also detailed. Topics in the handbook then segway into the realm of statistical inference and modeling with chapters dedicated to classical approaches as well as modern latent variable approaches. Numerous chapters associated with longitudinal data and more specialized techniques round out this broad selection of topics. Comprehensive, authoritative, and user-friendly, this two-volume set will be an indispensable resource for serious researchers across the social, behavioral, and educational sciences.
