Download or read book Hidden Handedness written by Samuel M. Randolph and published by Virtual Bookworm.Com Pub Incorporated. This book was released on 2007-01 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Children whose dominant handedness is purposefully reversed may undergo profound alterations in their developing brains. Hidden Handedness tells this story from an autobiographical point of view. The story opens with the experiences of an adult who learns at age 41 that he belongs to a group of people whose handedness had been reversed. Such people are called submergees in the book. The surprising discovery initiates a return journey in which the submergee becomes an emergee: one who migrates back by reversing behaviors relating to handedness, experiencing an amazing rebirth of body and mind. "Hidden Handedness" reviews supporting research, looks at biographies of famous submergees such as President Ronald Reagan, and uses stories to help complete the picture. Anyone who wishes to investigate the untold story of handedness reversals and returns would do well to begin with this book. Current research findings concerning plasticity in the adult brain, glia, mirror neurons and therapies such as Constraint Induced Therapy, provide growing support for the story told in "Hidden Handedness." This largely untouched terrain of the body and mind beckons to those who may be submergees and those who wish to know more about them.
Download or read book The Puzzle of Left handedness written by Rik Smits and published by Reaktion Books. This book was released on 2011-10-15 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ronald Reagan and Barack Obama have both signed bills into law with their left hands. And being left-handed certainly did not hold back the artistic achievements of Michelangelo or Raphael. And the dexterous guitar playing of Jimmi Hendrix may only have been aided by his southpaw tendencies. Left-handedness, in fact, would appear to be no big deal. Yet throughout history, it has been associated with clumsiness and generally dubious personality traits like untrustworthiness and insincerity. Even the Latin word for left, sinister, has ominous connotations. In The Puzzle of Left-handedness, Rik Smits uncovers why history has been so unkind to our lefthanded forebears. He carefully puts together the pieces of the puzzle, presenting an array of historical anecdotes, strange superstitions, and weird wives’ tales. Smits explains how left-handedness continues to be associated with maladies of all kinds, including mental retardation, alcoholism, asthma, hay fever, cancer, diabetes, insomnia, depression, and criminality. Even in the enlightened twenty-first century, left-handedness still meets with opposition—including from one prominent psychologist who equates it with infantile negativism, similar to a toddler’s refusal to eat what’s on his plate, and another who claims that left-handed people have average lifespans that are nine years shorter than those who favor the right hand. As Smits reminds us, such speculation is backed by little factual evidence, and the arguments presented by proponents of right-handedness tend to be humorously absurd. The Puzzle of Left-handedness is an enlightening, engaging, and entertaining odyssey through the puzzles and paradoxes, theories and myths, of left-handed lore. Chock full of facts and fiction, it’s a book to be read with both hands.
Download or read book Neuropsychology of Left Handedness written by Jeannine Herron and published by Elsevier. This book was released on 2012-12-02 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neuropsychology of Left-Handedness focuses on the neurological imperative and unique brain organization of left-handers. This book is organized into two parts. Part I analyzes ideas about the origins of left-handedness, such as possible genetic mechanisms, manner in which asymmetries may occur during the first cell cleavages following fertilization, handedness of twins, and possibility that some left-handedness may be due to environmental or even pathological influences. The second part is devoted to a variety of investigations of asymmetric hemisphere specialization in right- and left-handers. The different groups of left-handers, which includes male and female, strong left-preferrers and ambidexters, familial and non-familial lefthanders, and those who prefer an "inverted position for writing as opposed to a "non-inverted position, are also identified. This publication is a good reference for medical practitioners and specialists interested in the neuropsychology of left-handedness.
Download or read book On the Other Hand written by Howard I. Kushner and published by JHU Press. This book was released on 2017-09-25 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Does being left-handed make a person different in any way that matters? Since the late Stone Age, approximately 10 percent of humans have been left-handed, yet for most of human history left-handedness has been stigmatized. In On the Other Hand, Howard I. Kushner traces the impact of left-handedness on human cognition, behavior, culture, and health. A left-hander himself, Kushner has long been interested in the meanings associated with left-handedness, and ultimately with whether hand preference can even be defined in a significant way. As he explores the medical and cultural history of left-handedness, Kushner describes the associated taboos, rituals, and stigma from around the globe. The words “left” and “left hand” have negative connotations in all languages, and left-handers have even historically been viewed as disabled. In this comprehensive history of left-handedness, Kushner asks why left-handedness exists. He examines the relationship—if any—between handedness, linguistics, and learning disabilities, reveals how toleration of left-handedness serves as a barometer of wider cultural toleration and permissiveness, and wonders why the reported number of left-handers is significantly lower in Asia and Africa than in the West. Written in a lively style that mixes personal biography with scholarly research, On the Other Hand tells a comprehensive story about the science, traditions, and prejudices surrounding left-handedness.

Download or read book Handedness and Brain Asymmetry written by Marian Annett and published by Psychology Press. This book was released on 2013-04-15 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brain asymmetry for speech is moderately related to handedness but what are the rules? Are symmetries for hand and brain associated with characteristics such as intelligence, motor skill, spatial reasoning or skill at sports? In this follow up to the influential Left, Right Hand and Brain (1985) Marian Annett draws on a working lifetime of research to help provide answers to crucial questions. Central to her argument is the Right Shift Theory - her original and innovative contribution to the field that seeks to explain the relationships between left-and right-handedness and left-and right-brain specialisation. The theory proposes that handedness in humans and our non-human primate relations depends on chance but that chance is weighted towards right-handedness in most people by an agent of right-hemisphere disadvantage. It argues for the existence of a single gene for right shift (RS+) that evolved in humans to aid the growth of speech in the left hemisphere of the brain. The Right Shift Theory has possible implications for a wide range of questions about human abilities and disabilities, including verbal and non verbal intelligence, educational progress and dyslexia, spatial reasoning, sporting skills and mental illness. It continues to be at the cutting edge of research, solving problems and generating new avenues of investigation - most recently the surprising idea that a mutant RS+ gene might be involved in the causes of schizophrenia and autism. Handedness and Brain Asymmetry will make fascinating reading for students and researchers in psychology and neurology, educationalists, and anyone with a keen interest in why people have different talents and weaknesses.
Download or read book Laterality written by Clare Porac and published by Academic Press. This book was released on 2015-12-22 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Left-handedness has been connected to many different conditions, traits, and abilities. This is especially true for pathological syndromes, such as schizophrenia, along with learning disabilities and autism. The published research on handedness is vast and frequently contradictory, often raising more questions than providing answers. Questions such as: - Is handedness genetic? - Can handedness be changed? - Are there consequences to training someone to switch handedness? - Are there positive traits associated with left-handedness like creativity? - Are there negative traits associated with left-handedness like trouble reading maps? - Is it abnormal to do some things right-handed and other things left-handed? - Are the brains of left-handers different from the brains of right-handers? Laterality: Exploring the Enigma of Left-Handedness examines the research conducted over the past 50 years with special emphasis on twenty-first century research on handedness and translates this literature into an accessible and readable form. Each chapter is based on a question or questions covering diverse topics such as genetic and biological origins of handedness, familial and hormonal influences on handedness, and the effects of a majority right-handed world on the behaviors of left-handers. - Summarizes scientific research on laterality - Separates fact from fiction in common beliefs about laterality - Includes illustrative interviews with left-handers
Download or read book Left Handedness Behavioral Implications and Anomalies written by S. Coren and published by Elsevier. This book was released on 1990-06-26 with total page 595 pages. Available in PDF, EPUB and Kindle. Book excerpt: Left-handedness has been shown to be a possible marker for various psychological and physical abnormalities. This book presents evidence by a number of researchers who evaluate whether there are indeed differences between left- and right-handers which extend into the broader psychological and physiological realms.Several chapters show that left-handedness is found in unexpectedly high proportions in populations that suffer from various immune deficiency diseases, in alcoholics, dyslexics, mental retardates, psychopaths and other clinical groups. The book indicates why left-handedness should be a marker for such conditions. The genetic and environmental pressures on handedness are explored. A model for pathological left-handedness is presented, along with some interesting data which suggests that left-handedness may be associated with reduced life-span. Finally, several chapters discuss the implications of handedness patterns in non-clinical populations.
Download or read book Asymmetry in Plants written by Bir Bahadur and published by CRC Press. This book was released on 2019-03-25 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants exhibit forms of asymmetry analogous to "handedness" in bilaterally symmetrical animals. This book explores the evolutionary significance and development of asymmetry. Examples of genetic control include the direction of tendril or stem coiling of many climbing plants; the so-called spiral phyllotaxy and floral taxy; and contorted petal arrangement is another kind of left- right symmetry in plants; the direction of contortion is fixed in some but not in other plants. The book will underscore tha all phenomena related to handedness start during embryogenesis itself, with the occurrence of embryo rotation. Key selling features: First consolidated book on Plant Handedness Relates handedness, asymmetry and chirality to the evolution of different organizational levels in plant biology Emphasizes handedness as a vital governing force in plant functional evolution Provides a new perspective, hitherto ignored, into plant developemtn and evolution Describes how an age-old phenomenon can give scope for investigation from a very modern interdisciplinary approach

Download or read book Manual Asymmetries Handedness and Motor Performance written by Pamela Bryden and published by Frontiers Media SA. This book was released on 2016-06-10 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: The performance of most tasks with one hand, typically the right, is a uniquely human characteristic. Not only do people prefer to use one hand rather than the other, but also they usually perform tasks faster and more accurately with this hand. The study of manual asymmetries and what such performance differences between the two hands reveal about brain organization and motor function has been a topic of considerable research over the last several decades. The aim of this Research Topic is to review and further explore the origins of manual asymmetries and their relationship to handedness, unimanual and bimanual motor performance, and brain function. The articles included here involve original research conducted in humans or non-human models species, as well as theoretical perspectives, review articles, and meta-analyses.
Download or read book Beyond Left and Right Handedness written by Elke Kraus and published by Springer Nature. This book was released on 2023-08-16 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Handedness is a multidimensional phenomenon co-determined by polygenetic and developmental aspects, multifactorial influences and in some cases, pathological impact. It is important for professionals working with children, including those who are still undecided about their writing hand, to assess, analyse and understand the complexity of handedness comprehensively to prevent problems related to switched or atypical handedness. Beyond Left and Right Handedness uses a practice-based approach to handedness and systematically integrates theory, research and practice. Part I, ‘Theory and Research,’ critically evaluates and utilises the broad spectrum of the handedness literature as a theoretical basis for the development of handedness instruments. Part II, ‘Assessment and Analysis,’ presents diagnostic and analytical instruments developed by the author based on numerous in-depth studies and extensive clinical practice over 20 years. These include the Handedness Profile, a standardised assessment of various handedness dimensions; and the Handedness Typology, an analytical framework to interpret different types of handedness. Part III, ‘Implications for Practice,’ contains detailed case studies on assessment and treatment by professionals working with children presenting with unclear and/or atypical handedness. “This book provides the reader with a comprehensive and scholarly discussion of the topic, presenting a careful, in-depth description of all aspects of the topic and providing professionals with the necessary, evidence-based tools to address handedness in practice. It is an invaluable resource that is well situated in the latest evidence-based understanding of handedness and provides a comprehensive guide to addressing the important development of handedness.” - Prof. Dr. Helen Polatajko
Download or read book How Handedness Shapes Lived Experience Intersectionality and Inequality written by Peter Westmoreland and published by Springer Nature. This book was released on 2023-03-13 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book delivers philosophy’s first sustained examination of handedness: being left-handed, right-handed, etc. It engages literature from phenomenology and continental philosophy, analytic philosophy, laterality studies, cognitive science and psychology, gender studies and feminist philosophy, sociology, political science, and more to provide a systematic accounting of the nature of handedness, its basis in lived experience, its effects on bodily performance, its role in varieties of inequality, and its part in oppression and liberation. As a radical asymmetry in the body, handedness plays a key role in human flourishing. It informs both personal bodily movement and social life, from handshakes and high fives to high tech tools made for one hand or the other. Moreover, with left-handers making up just 10% of the population, handedness presents a significant inequality in lived experience. To live and live well, we must understand handedness.

Download or read book Handedness and Developmental Disorder written by D. V. Bishop and published by Cambridge University Press. This book was released on 1990 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive and readable account of theoretical aspects of the origins and normal development of handedness and its relationship to cerebral lateralization. It reviews the evidence for links between non-right-handedness and various developmental disorders: mental impairment, autism, epilepsy, and disorders of spoken and written language. The emphasis is on understanding the range of underlying mechanisms that might lead to associations between handedness and disorder and on identifying assessment procedures that can distinguish between different explanations.
