So for all of you lefties, leftie-loving righties, and ambidextrous folks out there — it’s time to brush up on your left-handed knowledge and help put an end to leftie discrimination once and for all. Since most right-handed people use the left hemisphere of the brain to process language, that must mean that left-handed people think with the right side of the brain, right? Dr. Grimshaw found that while 98 percent of righties are left-brained, so are 70 percent of lefties. “For the most part, left-handers do not differ obviously from right-handers. They certainly don’t have reversed brains,” Grimshaw told Health. National Library of Medicine, multiple factors including genetics, environment, and chance determine whether a person is left-handed.
While majorities across various demographic groups are more likely to describe their searches as easy, rather than difficult, there are some differences by gender. If you’re a righty and ever used your left hand to cut with scissors, you know it’s awkward. Lefties can find a growing number of products for the kitchen, office, and elsewhere that are designed with them in mind.
Left-Handed Personality Traits And Characteristics
This could be the first signs of a left-handed child, say the researchers. In one 2008 Swedish study of moms and their 5-year-old children, women who were depressed or stressed during their pregnancies were more likely to have mixed- or left-handed kids. In other studies, babies with low birth weight, or born to older mothers, were more likely to be lefties as well. According Meetville to the American Psychological Association, 10 percent of the population is left-handed. Onestudy in the Journal of Mental and Nervous Disease musicians, painters and writers were significantly more likely to be left-handed. However, a conflicting study of more than 1,000 people debunked the myth that “right-brained” people are more creative than “left-brained” people.
While today lefties are living in a righty’s world, struggling with supplies and technology not designed for them , it’s time we show some love to the left-handed. In many cultures and countries, being a left-hander is thought to be unnatural. In eastern countries like India or in the Middle East, left-handedness is thought to be rude.
However, a newer study suggests that the gene activity in the spinal cord is the determining factor when it comes to the dominant hand. As our world is designed mainly for righties, left-handed people have become quite deft in doing certain things with their right hands. Lefties have a particular advantage over righties in certain sports, like fencing, boxing, tennis, baseball, and swimming. Righties are more used to playing against other righties, which may throw them off their game a little when they have to play against a leftie. For example, a batter in baseball is more likely to be more accustomed to pitches by a righty, so they are more likely to miss when receiving a pitch by a lefty. This is especially seen as more prevalent in Tennis, where around 40% of the current top players are lefties.
Tools Made Specifically for Lefties
Generally, males are three times more likely to be left-handed than females. Statistically, one twin of a pair has a 20% chance to be left-handed. Gay people may be up to 39% as likely to be left-handed as straight people . This may have important implications in caring for anxiety and mood disorders, which are sometimes treated using brain stimulation to increase neural activity in the left hemisphere.
In a 2011 University of Toledo survey of 100 sleep clinic patients, researchers found that 69% of right-handers experienced limb movements on both sides of their body while sleeping. As for the left-handed patients, 94% of them had these movements. In a 2005 French study, researchers found that southpaws made up just about 3% of the population in the most peaceful primitive societies, but 27% in the most warlike ones. It goes back to the idea that lefties have a physical advantage over righties.
These Sleep Habits Are Putting Your Heart Health At Risk
A lot of these associations, she says, are the result of what’s called selective reporting bias. Scientists add a question about handedness into their study on, for example, creativity, and become excited if they find a positive association, but don’t report the instances when no connections are found. We know that left- and right-handedness has a genetic origin.
What Makes Left-handed People Unique?
Sinistrophobia is defined as the fear of things at the left side or left-handed people. Lefties can easily learn to use their right hand if they injure the left one. Tennis champion Rafael Nadal is actually right-handed but learned to play lefty to gain a competitive edge. Also, according to research conducted at Lawrence University in New York, there were more left-handed people over IQs of 140 than right-handed people.
In violent societies, researchers theorize, left-handers benefit from their unexpected left hook. Do you or your left-handed friends have a knack for reading maps, remembering parking spaces, and figuring out how to get from Point A to Point B? According to a classic study, researchers observed that left-handed people showed a lower rate of error in a spatial orientation test than righties. Spatial skills will always be important ––you never know when you and your right-handed counterparts will get lost in the woods and you’ll be able to save the day. “I remember back in high school a friend had told me that being a lefty was going to be made into a handicap,” says Danielle Becker, a mixed media artist and the founder of Leftys Right Mind. “Besides being the only one in class with the side of their hand completely covered in pencil, I never felt being a lefty inhibited me from excelling in my work, let alone hold me back in life.
Research has shown that left handed people are more likely to practice inductive logic when problem solving. This research has also identified that the two top fields for left handed people were technology and the arts. Oddly enough both require the ability to think outside the box yet to be able to use logic because both are heavy in technical expertise. The premise of this theory is that since both speaking and handiwork require fine motor skills, having one hemisphere of the brain do both would be more efficient than having it divided up. And since in most people, the left side of the brain controls speaking, right-handedness would prevail.
