Book Description

We report an experimental study designed to test the following hypothesis derived from clinical observations: There is an elevated frequency in left-handed individuals and in their families of immune disease, migraine, and developmental learning disorders. In two separate investigations the frequency of these conditions was compared in strongly left-handed subjects and in strongly right-handed controls. In each of the investigations we found markedly higher frequencies of immune disease in the left-handers than in the right-handers. The rate of learning disabilities was also much higher in the left-handers than in the right-handers in both investigations. In a second study the frequency of left-handedness was compared in patients with migraine or immune disease and in general population control subjects free of these disorders. There was a higher frequency of left-handedness in patients with migraine and myasthenia gravis than in controls. We present a brief outline of a hypothesis that may account for an increased frequency of immune disease in left-handers and in their families.

Book Description

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

Book Description

If you are among the 10 percent of people who happen to be left-handed, you've had to endure such derisive terms as "gauche" and "a left-handed compliment." At school you may have been forced to write with your right hand. And in another century your proclivity might have gotten you accused of witchcraft. Any left-handed person, or the spouse, parent, or friend of one, will be captivated by this essential and eye-opening book. With bracing wit and a flawless command of current research, psychologist Stanley Coren answers such questions as: Is left-handedness acquired genetically or socially? Are southpaws more creative than their right-handed fellows? Why do left-handers seem to die younger than right-handers? What can left-handers do to counteract the perils and prejudices that confront them in a world that leans to the right?
