Creativity may come more easily for left-handed people In the early 2000s, multiple research groups found an intriguing link between highly creative people — such as professional musicians and visual artists — and high levels of schizotypy.
A 1970s study from the University of Cincinnati found that that among students who majored in music and the visual arts, there were more left-handers than among students who majored in natural sciences (Peterson, 1979).
58% were right-handed artists
I provided no definition - I just asked whether people considered themselves a left-handed artist - and 31% did while 40% could use their left hand for art.
In a 1996 study, Harvard Medical School researchers found that orthopedic surgeons, librarians and mathematicians were mostly right-handed while attorneys and architects were, as a group, “either the least right-handed or the most left-handed.” Other studies have shown that there are more left-handed people working as ...
While this is still contested, studies have found that artists like painters, musicians and even architects are mostly left-handers. Right and left-handed people deal with tasks and memory in different ways. Left-handers are known to efficiently multitask as they look at the tasks as a whole.
Although the percentage varies worldwide, in Western countries, 85 to 90 percent of people are right-handed and 10 to 15 percent of people are left-handed. Mixed-handedness (preferring different hands for different tasks) and ambidextrousness (the ability to perform tasks equally well with either hand) are uncommon.
Most of the current research suggests that left-handedness has an epigenetic marker—a combination of genetics, biology and the environment. Because the vast majority of the population is right-handed, many devices are designed for use by right-handed people, making their use by left-handed people more difficult.
For example, left handedness determined by grip strength has been shown to be associated with poorer cognitive function [12], whereas left handedness, via self-report, has been shown to be associated with better memory and attention task performance [13].
Albert Einstein. Lefties are often considered creative, so it's no surprise that many famous inventors and great minds were left-handed, including Einstein, Marie Curie, Ben Franklin, and Henry Ford. Bill Gates is also a southpaw.
Being left-handed also has its perks, including: Left-handed people are at an advantage in a wide range of sports, from fencing to boxing. The sporting advantage also includes taking the right-handed opponent by surprise, because right-handed athletes aren't used to playing against left-handed opponents.
-Counting how many people are left-handed is more difficult than it looks, because of variations in preference and skill from task to task and because of left-handers having been forced to write with their right hand, but the best estimate we have is that roughly 10% of the world population is left-handed.
Picasso was right-handed, making his left the only one that could serve as his subject.
Brain scans indicate that left-handed people think differently from right-handed people. They tend to activate the right half of their brain more for certain tasks and functions. Experts suggest that this difference in brain function could make creativity come more easily.
Van Gogh was right-handed. We are almost certain of this, because in two self-portraits, he's pictured with the pallet in his right hand. But because he painted himself using a mirror, you need to flip that image.
“Most left-handers seem to have similar language processing to right-handers,” Grimshaw says. For other one-sided brain functions, such as attention, emotion, music, and face perception, she says, there are less data. “But for the most part, left-handers do not differ obviously from right-handers.
Our confidence intervals at a 95% confidence level show that the average IQ for a left handed person is between 117.73 and 127.19 and for a right handed person it is between 109.9 and 123.5.
In fact, the difference is 90:10. This means that dyslexia may be more commonly found in left-handed people but the relationship is not necessarily causal. There is also the question of whether or not it is more common in boys than girls.
Why do left handed writers have a poor reputation for neat writing? Left handed people face a lot of difficulties in everyday life. Handwriting can be particularly hard for lefties, especially if they are taught by a right handed person, as the grip of the pen and formation of letters is different.
Left-handedness occurs in about 8% of the human population. It runs in families and an adoption study suggests a genetic rather than an environmental origin; however, monozygotic twins show substantial discordance.
Special or not, lefties are born, not made: Genetics are at least partially responsible for handedness. Up until last year, it was assumed that hand preference comes from asymmetrical genes in the brain—two hands, two brain hemispheres, one is dominant.
If two parents are right-handed, their offspring has a 10% chance of being left-handed. However, if one or both parents are left-handed, the chance of their child being left-handed becomes higher at 18 to 22% and 27%, respectively.
'If a lefty writes with his right hand it's bad, because we're changing the hand but not the leading eye or the leading foot. ' So a child who has had his hand changed is more prone to distraction; he absorbs information more poorly. As a result, he can become more irritable.
One biological effect on hand preference is known to be sex, with males more likely to be left-handed than females2,14. For example, in a U.S. dataset aged 10–86 years, the proportion of non-right-handers among 664,114 women was 9.9%, versus 12.6% among 513,393 men2.
This is called the Homo loquens hypothesis: lateralisation in general was driven by the evolution of an upright, bipedal stance, while the rightward preference was driven, some time later, by the evolution of language.
