Scientists at the Wellcome Trust Centre for Human Genetics, University of Oxford, have identified a genetic variant which influences whether a person with dyslexia is more skilled with either the left or right hand. The finding identifies a novel gene for handedness and provides the first genetic evidence to support a much speculated link between handedness and a language-related disorder. The majority of people worldwide are right-handed. Since the left side of the brain controls the right...

"In laboratory tests, right- and left-handers associate positive ideas like honesty and intelligence with their dominant side of space and negative ideas with their non-dominant side," says Daniel Casasanto of the Max Planck Institute for Psycholinguistics in Nijmegen, Netherlands. To find out whether people link 'good' with 'dominant' beyond the laboratory, Casasanto and co-author Kyle Jasmin examined spontaneous gestures during positive and negative speech in the final debates of the most...

Gay men can recall familiar faces faster and more accurately than their heterosexual counterparts because, like women, they use both sides of their brains, according to a new study by York University researchers. The study, published in the journal, Laterality: Asymmetries of Body, Brain and Cognition, examined the influence of gender, sexual orientation and whether we're right-or-left-handed on our ability to recognize faces. It found that when memorizing and discriminating between faces,...

Despite the almost universal association of the right with life, right, positive and good things, and the left with death, inadequacy, negative and bad things, recent researches show that left-handed people hold the opposite association. Thus, left-handers become a critical case in which conceptual associations, result of a sensory-motor experience, and those that rely on linguistic and cultural uses, are contradictory. A sensory-motor experience in itself is capable of creating abstract...

Children who are mixed-handed, or ambidextrous, are more likely to have mental health, language and scholastic problems in childhood than right- or left-handed children, according to a new study published today in the journal Pediatrics. The researchers behind the study, from Imperial College London and other European institutions, suggest that their findings may help teachers and health professionals to identify children who are particularly at risk of developing certain problems. Around one...

There are areas in the brain devoted to our arms, legs, and various parts of our bodies. The way these areas are distributed throughout the brain are known as "body maps" and there are some significant differences in these maps between left- and right-handed people. For example, in left-handed people, there is an equal amount of brain area devoted to the left and right arms in both hemispheres. However, for right-handed people, there is more cortical area associated with right arm than the...

A new study by scientists in France offers a possible explanation for left-handedness, finding that the trait survived since prehistoric times in part due to its rarity, which offered benefits. The question of why some people are left-handed while the vast majority of humans are right-handed has puzzled scientists, who have long believed that genes that don't aid in the struggle to survive typically get squeezed out of the genetic code, leaving instead the ones that are fitter. However, in...

A new study suggests people who are "mixed-handed," those who are able to use both hands with equal dexterity, may have a harder time conceiving a child than righties or lefties. A study of more than 9,000 Danish couples showed that those in which one partner was mixed-handed, rather than exclusively right- or left-handed, tended to take slightly longer to conceive. Mixed-handedness, also known as cross-dominance, is being able to do different tasks better with different hands. For example,...

New research points a finger to left-handed people who are more likely to get anxious or feel shy or embarrassed about saying or acting on what they want. Researchers at Abertay University gave the study participants a behavioral test that gauges personal restraint and impulsiveness. Left-handers agreed more with statements such as "I worry about making mistakes." They also noted in the test that "criticism or scolding hurts me quite a bit." Dr Lynn Wright, who led the study in Dundee,...

NEW YORK (Reuters) - Left-handed men, often seen as having an advantage over right-handed counterparts in sports like tennis, also enjoy much better paydays, a new study says. Left-handed men with at least some college education earned 15 percent more than similarly educated right-handers, while those who finished college earned about 26 percent more, wrote Christopher S. Ruebeck of Lafayette College, and Joseph Harrington and Robert Moffitt of Johns Hopkins University in a paper...
