Available in PDF, EPUB and Kindle. Book excerpt: 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 frequency of different twin types and the varieties of polar body twin pairs. This book will inform and entertain behavioral and life science researchers, health professionals, twins, parents of twins, and anyone interested in the fascinating topic of twins. - Identifies common misunderstandings about twins - Provides scientific answers to questions about twins - Encompasses the biology, psychology, genetics, and personality of twins - Includes discussion of identical, fraternal same-sex, and fraternal opposite-sex twins - Allows for quick answers to common questions and more detailed explanations

Available in PDF, EPUB and Kindle. Book excerpt: This volume reports on a study of 850 pairs of twins who were tested to determine the influence of heredity and environment on individual differences in personality, ability, and interests. It presents the background, research design, and procedures of the study, a complete tabulation of the test results, and the authors’ extensive analysis of their findings. Based on one of the largest studies of twin behavior conducted in the twentieth century, the book challenges a number of traditional beliefs about genetic and environmental contributions to personality development. The subjects were chosen from participants in the National Merit Scholarship Qualifying Test of 1962 and were mailed a battery of personality and interest questionnaires. In addition, parents of the twins were sent questionnaires asking about the twins’ early experiences. A similar sample of nontwin students who had taken the merit exam provided a comparison group. The questions investigated included how twins are similar to or different from nontwins, how identical twins are similar to or different from fraternal twins, how the personalities and interests of twins reflect genetic factors, how the personalities and interests of twins reflect early environmental factors, and what implications these questions have for the general issue of how heredity and environment influence the development of psychological characteristics. In attempting to answer these questions, the authors shed light on the importance of both genes and environment and form the basis for different approaches in behavior genetic research.

Download or read book Twin Lateralisation written by Michael C. Corballis and published by Psychology Press. This book was released on 1999 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twins present special problems for the study of lateralisation, both psychological and biological. Central to both areas is the common observation that identical (monozygotic) twins can differ in their laterality. In the case of hand preference, this is most obvious in the one in five twin pairs where one is right-handed and the other left-handed. A similar problem can be found morphologically, not only in normal anatomical traits, such as hair whorls, which can be in opposite direction, but also in the rare condition of conjoined twins, where it is frequently the case that one twin has its heart and viscera in the normal orientation (situs solitus) and the other is mirror reversed (situs inversus). This special issue of Laterality brings together papers on these different aspects of twinning. Two of the papers are biological, one providing a detailed analysis of the laterality of artificially conjoined twins created by fusing two different species of newt, and the other overviewing the recent developments in understanding the molecular biology of visceral lateralisation in relation to twinning. The other papers concern aspects of cerebral lateralisation in twins, one providing a much needed meta-analysis and critical overview of the twin literature, another providing detailed data from a large study of handedness in twins, a third asking about the almost neglected question of footedness, earedness and eyedness in twins, and the fourth looking at lateralised cognitive processing. Between them these papers extend the literature on lateralisation in twins, and reinforce the need to consider the lateralisation of twins from biological, neurological and psychological perspectives.

Download or read book Quadruplets and Higher Multiple Births written by Marie M. Clay and published by Cambridge University Press. This book was released on 2011-12-14 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: The advent of hormonal infertility treatments and in vitro fertilization techniques have led to a sharp increase in the number of quadruplet and higher-order conceptions in recent years. Improved neonatal care and nutrition have meant that many more of these babies survive. Yet it appears that very little research has been done into the lives of such children and the psychodevelopmental consequences of their multiple status. In this book, Marie M. Clay brings together what is known from historical records and reports in the medical, psychological, and popular press. She points to the contribution that research studies on higher multiple sets could make to our understanding of genetic-environmental interactions and gives valuable methodological advice for those wishing to initiate such a study. Changes in social practices and medical knowledge are highlighted, various aspects of pregnancy and birth are discussed, and the practical and emotional problems faced by families of multiple sets are sensitively described. Appended to the book are an illustrated "Catalog" of quadruplet case reports gleaned from the literature, including birth details and postnatal histories, plus a directory of multiple birth associations, support groups, and study centers around the world.

Available in PDF, EPUB and Kindle. Book excerpt: Genetic differences in humans, like those between individuals of any animal or plant species and those between species, are all products of the evolutionary development of the living world. These differences, with their behavioral consequences, can only be understood in the light of evolution. Our understanding of evolution, however, has itself evolved. The Darwin- Wallace theory of evolution appeared in the nineteenth century. Since then, development of evolutionary thought has gone through several stages. The contributions in this volume describe those stages.

Available in PDF, EPUB and Kindle. Book excerpt: Heredity and Environment in the Functional Psychoses involves an epidemiological clinical study of twins carried out at the University Psychiatric Institute in Oslo. The author reviews the history and nosological aspects of psychiatry. In his study of twin genetics, the author seeks to answer the questions "What is inherited?" and "How is it inherited?" In his review of 342 pairs of twins in the Central Register of Psychosis, his study had the following aims: to obtain true concordance figures for all types of functional psychoses; to study problems pertaining to nosology; and to study a larger sample of discordant pairs in order to clarify crucial environmental factors. His findings show that concordance figures for schizophrenia are 25-38 per cent in monozygotic twins and 4-10 per cent ion dizygotic twins. He points out that the difference in such concordance rates between the two types of twins is statistically significant. The data supports the (weak) assumption of a genetic factor in the etiology of schizophrenia. Behavioral scientists, psychiatrists, child psychologists, and researchers involved in genetics will find this book helpful and informative.
