Personality characteristics of left-handed people

Personality characteristics of left-handed people

What are the personality characteristics of left-handed people? In daily life, when we see left-handed people, we think they are special because they are different from ordinary people. He works with his left hand, so what are the personality characteristics of left-handed people? Let's have a look!

Personality characteristics of left-handed 1

First, the posture is smart.

Most of us are used to working with our left hand, so many people think that the posture of our right hand should be slower. It's actually wrong. Right-handed people exercise hard, just like many left-handed people. Their posture is very dexterous, and some even do it as fast as their left hand. For example, many athletes in China are right-handed, such as Wang, Hao Shuai and Xu Xin who play badminton. For example, Dānlín, Li Wei and Fu Haifeng, who play table tennis, are also very good, and their postures are also very dexterous.

Second, the right brain is developed.

I firmly believe that everyone knows that the left hemisphere of left-handed people is more developed, and of course the right hemisphere of right-handed people is also more developed. Generally speaking, a developed person in the right hemisphere has a different way of thinking, and is smarter than other children in some aspects, with strong hands-on ability and strong working ability. Therefore, for right-handers, it is very suitable to choose some hands-on work such as mobile games and programming.

Third, strong thinking logic.

People who are used to doing things with their left hands are also relatively fixed and stick to the rules, while right-handed people have different ways of thinking and stronger logic. For example, in the case of study and training, their test scores in physics, logical reasoning, mathematics and other courses are generally good, so these children generally choose science and engineering when choosing subjects. Therefore, if you sign up for work in the future, you can do some serious and meticulous work, such as criminal defense lawyers, which is a very good choice.

Fourth, strong art painting skills.

We all know that right-handed people have a unique way of thinking. For people with this kind of brain hole, the foundation of art painting is also very good. For example, Michael Jackson, a well-known painter, is right-handed. Therefore, if there is a right-handed baby at home, they can shape their professional skills in these areas when they are young, and they can also be employed at the level of literary and artistic standards when they grow up.

5. Good memory

Right-handed people also have strong memory ability, they can easily remember some fragmentary data and patterns, and such groups are generally smart. Therefore, their academic performance and work are excellent, faster and more efficient. For people with good memory, it is also appropriate to do some statistical analysis of data when registering for work.

Six, dexterous posture

Right-handed people are also very dexterous. Many athletes in China are right-handed, such as Wang, Hao Shuai and Xu Xin who play badminton. For example, Dānlín, Li Wei and Fu Haifeng who play table tennis are also very good.

Personality characteristics of left-handed people II

Features:

1, there is always a unique view different from others in some aspects. Left-handers often think of shaped images in their minds before writing or drawing, and many left-handers will try their best to reassemble the bits and pieces they can't remember into pages of pictures and remember them.

2. Strong mathematical ability, strong visual perspective ability and strong spatial ability are conducive to the development of mathematics and architecture. 1990 Annet &； Manning's research found a correlation between right-handedness and lack of mathematical ability.

3. If a right-handed person has a close relative (such as a brother or sister) who is left-handed, then the right-handed person's memory is better than that of a person whose whole family is pure right-handed. A study at the University of Toledo, Ohio, found that right-handed people whose close relatives are left-handed show strong situational memory (such as where the keys are conveniently placed after entering the door). Although the semantic memory stored in the database (such as the starting and ending years of World War II) is poor, it may be because the information itself has a left brain and the temporal and spatial background information of the event has a right brain, so combining the two can enhance the situational memory. Researchers suspect that the corpus callosum that may connect the left and right brains is very large, indicating that your brain structure is a mixture of the left and right halves.

4. Left-handed people seem to perform well in sports that require quick response and correct spatial judgment. People who are more flexible and stronger with their left hand, left foot and left eye, especially in tennis, football and golf, often perform better than others. Tennis celebrities such as Naratinova, Connors and mcenroe.

Left-handed people also have an advantage, because right-handed people are not used to playing with him. Some left-handers can even switch to the right hand to swing or swing when necessary, which most right-handers can't do. Like fencing, a sport in which two people fight each other, left-handed people also have special advantages, and the proportion of winning the championship is very high.

6. People with strong left hand, but strong right foot and strong right eye may have the problem of uncoordinated integration, which especially affects the action of swinging the racket, because the line of sight may sometimes be limited. But it is beneficial to gymnastics, running, basketball and other games that require a strong sense of physical balance.

7. It is much more difficult for a right-handed person to do things with his left hand than for a left-handed person. Moreover, left-handed people are more willing to listen, accept or consider other people's opinions and ideas. This is related to the fact that left-handed people have been adapting to the environment all their lives, learning when to cross their bodies with their left hands or when to switch to their right hands, and overcoming difficulties is related to constant practice.

8. Poor autoimmune system, including asthma, migraine, diabetes, autism (65% of autistic patients are left-handed), learning disabilities, paranoia and easy to go astray. However, in 199 1, another study refutes this theory.

Personality characteristics of left-handed people 3 20 little-known facts of left-handed people

Left-handed people only account for 10% of the total population, and it is easy to forget that they live in a right-handed world. However, left-handed people will not only make it difficult for scissors designed for right-handed people to cut straight lines, but also have some subtle effects on our physical and mental health. Left-handed people may have different brain and body functions from right-handed people (while left-handed people dominate different tasks with different hands). "The habit of using hands seems to be fixed at the very early stage of fetal development, and other things about your future are also fixed at this time," said Dr. Ronald Yeo, a psychology professor at the University of Texas at Austin.

Let's take a look at some of the most common facts about left-handed people and what it means to your health.

1 is not only related to genes.

Yeo said that scientists are not sure why some people are left-handed, but they know why genes account for 25%. He said that the habits of left-handed people can indeed be inherited in the family, "but compared with other genetic characteristics such as height or intelligence, this possibility is obviously less." In fact, identical twins with the same gene sometimes have different dominant hands. Yeo said that there are many theories about other factors that will affect which hand you write with, but many scientists think it is just an accident.

2. It is related to stress during pregnancy.

In a British study, the fetus of a pregnant woman under great stress is more likely to touch her face with her left hand than with her right hand. Researchers say this may be an early sign of left-handed babies. There is also evidence to support this theory. In a study of mothers and their five-year-old children in Sweden in 2008, women who were depressed or stressed during pregnancy were more likely to give birth to both children. In other studies, babies with low birth weight or babies of older women are also more likely to be left-handed.

3. More common in twins.

Identical twins are sometimes mirror images of each other-for example, if one of them has a mole on his right cheek, the other person will also have a mole in the same position on his left cheek. It was once thought that the genetic makeup of twins should also be "mirror images"-therefore, one should be left-handed and the other should be right-handed. People used to think that all left-handed people originally came from twins, and their right-handed brothers and sisters died in the womb. )

None of this is true, but the probability of finding left-handed twins is indeed twice that of the general population. 1996 A study in Belgium found that about 2 1% of identical and fraternal twins are left-handed.

4. This will not make you a "right brain type"

Dr Gina02Grimshaw, director of the Cognitive and Emotional Neuroscience Laboratory at Victoria University in Wellington, New Zealand, said that most right-handers use the left brain to process language, but this does not mean that most left-handers are "right-brained"-that's just a rumor. She said that about 98% right-handed people are left-handed, but so are 70% left-handed. Only 30% of left-handers are right-brained or left-balanced (that is, the abilities of the two hemispheres are equally divided). "Most left-handers seem to have similar language processing processes as right-handers," Grimshaw said. For the functions of the other brain (right brain), such as attention, emotion, music and facial perception, she said, there will be less data. "But in most cases, the difference between left-handed and right-handed is not obvious. Their brains have not been reversed. "

5. Different ways of thinking

Society tends to associate the left with bad things ("two two 02left02feet" means "clumsy"), and the right is often associated with good things ("my02right-hand02man" means "my right-hand man"). But according to a study by Stanford University in 2009, if you are left-handed, your thinking may be different from that of right-handed. Participants were shown two columns of abstract pictures and asked which column looked smarter, happier, more honest and more attractive. Right-handed people tend to choose pictures in the right column, while left-handed people tend to choose pictures in the left column. "For left-handers, they subconsciously think that the good things are on the left and the bad things are on the right, although when they are awake, everything in language and culture tells them that the left is not good and the right is good," the lead author of the study said in a press release. He thinks this may affect the way we vote or prefer candidates when watching the presidential debate.

6, affect academic performance

In a study of children aged 1 1 in 2009, Australian researchers found that left-handed children performed worse than right-handed children in several aspects, including vocabulary, reading, writing, social interaction and coarse and fine motor skills. Left-handed children perform even worse than left-handed children.

Yeo said that left-handed and left-handed children are more likely to use their two hemispheres in unusual ways, which puts them at risk of mild learning disabilities. However, at the same time, some left-handed children have some obstacles unrelated to learning, that is, it is difficult for them to decide which hand to write with. In any case, most children can keep up with their classmates when they grow up, he said-lefties or lefties may not be able to accurately predict how good their children will be when they grow up.

7. Mental health problems.

A study of Yale University 20 13 shows that left-handed people are at great risk of mental illness, such as schizophrenia. When researchers asked patients in mental health clinics, 40% of schizophrenics said they wrote with their left hand; This is much higher than the 10% of left-handed people in the general population. The study also found that the habit of using hands without the right hand is related to dyslexia, ADHD and some emotional diseases.

8. Sports competition has advantages.

Most hand habit experts agree that left-handed people have the upper hand in one-on-one sports such as tennis, boxing and baseball throwing. Linguist Rik02Smits explained in the book The Mystery of Left-Handers that (left-handed and right-handed) athletes usually compete with right-handed opponents. When they finally meet a left-handed opponent, left-handed people adapt easily-while right-handed people face a double disadvantage. "They (right-handed people) were forced to participate in an asymmetric battle with them (by hand), and they were not prepared enough to confront an opponent who was good at dealing with asymmetry," he wrote.

9, help to become a better soldier

In a study from France in 2005, researchers found that in the most peaceful primitive society, left-handed people only accounted for 3% of the population, while in the militant society, the proportion was 27%. Why? This goes back to the saying that left-handed people have physical advantages over right-handed people. In a violent society, researchers infer that left-handed people benefit from their unexpected left hook.

10, creativity is not better.

Yang said that left-handed people are usually considered to be more creative than right-handed, but it is difficult to measure. This rumor may come from a study in 1995, which found that left-handed men are more inclined to "divergent thinking" than right-handed men-meaning that they will explore more options to solve a problem instead of using ready-made things. For women, there is no difference in hand habits. "There is some truth in the idea of creativity, but when you look at a person's creative achievements in his life, the evidence has no strong connection with the left," Yeo said.

1 1 doesn't mean you have artistic cells.

Grimshaw said that left-handed people will also be praised as introverted and artistic. "This is an interesting contrast with the view in recent decades or earlier that the traditional left-handers are mentally or morally worse to some extent," she said. "However, traditional views can't reflect the facts." In a study of 20 13, Grimshaw and her colleagues found that there was no difference between left-handed and right-handed people in the five personality indicators they tested. However, they do find that left-handed generalists are more introverted.

12, the risk of breast cancer is higher.

Left-handers seem to be related to some health problems. In a study published in the British Journal of Cancer in 2007, researchers found that left-handed people have a higher risk of breast cancer than right-handed people, especially after menopause. Although they seem completely unrelated, Yeo thinks they are the result of something that affects the early development of the fetus. "We know that other physical weaknesses, such as low birth weight and small prenatal head circumference, can predict later (physical) health problems," he said. "Your development before birth will determine your strengths and weaknesses in later life."

13, which will not affect your overall health.

Scientists have long suspected that left-handed people are related to immune function to some extent and may be at risk of autoimmune disorder. Grimshaw said that research can't support most of these views, and most theories have been debunked. But an autoimmune disease that really seems to be related to hand habits is inflammatory bowel disease. A study of 200 1 in Britain found that left-handed people are twice as likely to suffer from Crohn's disease, ulcerative colitis and other intestinal diseases as right-handed people.

14, related to some sleep problems.

Left-handers may be more prone to periodic limb movements (PLMD), which will cause patients to kick and twitch unconsciously while sleeping. In a study of 20 1 1 00 outpatients in the University of Toledo, the researchers found that 69% of right-handed people have left and right limb convulsions during sleep. For left-handed patients, 94% will have limb convulsions. "Their research results show that left-handed people are more likely to suffer from periodic limb movements, which shows the potential possibility of suffering from periodic limb movements," said in the press release of the conference on 20 1 1.

15 may help to avoid ulcers and arthritis.

From the point of view of health and wisdom, being left-handed is not all bad. A study published in the journal laterality in 2005 found that the probability of left-handed people suffering from ulcers and arthritis is very low. "The possible explanation is that both hand habits and disease risk depend on the interaction of hundreds of genes (we no longer think that one or two genes can explain everything), and they may all have the same gene," Grimshaw said. "But we don't know what these genes are, and this is an active research field at present."

16, which does not affect the life length.

Because of a study by British Columbia University 199 1, people once thought that left-handed people were doomed to die earlier than their "normal" peers. The study also found that car accidents are often the culprit, so left-handed people also take the blame for bad drivers. But since then, several studies have debunked these assertions, and now scientists generally believe that being left-handed or right-handed has no effect on life expectancy.

17 may increase the risk of post-traumatic stress disorder.

A study in Scotland in 2007 found that left-handed people are more likely to show symptoms of post-traumatic stress disorder after watching a thriller movie. Other studies have found that non-right-handed users feel more negative emotions. These findings are based on the fact that non-right-handed users tend to have unconventional brain lateralization, which will affect the way their brains deal with fear and anger.

18 will not make you more addicted to alcohol.

Many small studies show that left-handed people drink more than right-handed people, but scientists don't know why. They suspect that left-handed people use their brains in unusual ways, making it easier for them to drink, or that left-handed people just want to relieve the pressure of being a minority in the right-handed world. Therefore, a study published in the British Journal of Mental Health on 20 1 1 investigated this problem with self-reported data of more than 27,000 people. They found that left-handed people don't tend to drink more, but mainly because they are "unlikely to drink less (less than 1 ounce per month) or not to drink at all." In other words, left-handed people are less likely to drink or become alcoholics. "There is no reason to think that this is related to excessive drinking or dangerous drinking," the author wrote.

19, which may mean that you earn less money.

Whether the cognitive, mental and physical differences between left-handed and right-handed people will really have an impact in the real world of people's lives remains to be discussed-but the study of Harvard University 20 14 shows that this may be different. Joshua Goodman, a researcher, found that the average salary of left-handed people is 9- 19% lower than that of right-handed people of the same age. The gap between left-handed and right-handed people is about $2,500 for men and $3,400 for women. He also found that left-handed people are more likely to not go to college or drop out of school and engage in jobs with lower cognitive requirements, such as manual labor. "When people ask my conclusion, I tell them that it makes me pay special attention to the development of my children's hand habits," Goodman said at a news conference. "But if they are really left-handed, I won't worry, but I will be wary of other things."

Generally speaking, it is not important to get used to using your hands.

Yeo said that among all these interesting facts about hand habits, perhaps the most important thing is that it is not that important at all. He said: "The difference between left-handed people and right-handed people is really subtle. There are more elements of scientific (exploratory) interest than practical application."

Grimshaw agrees with this view. She emphasizes that it seems that the difference between people who are both left-handed and right-handed is much greater than that between left-handed and right-handed. "However, we don't know the brains of left-handed people, because so far, we have paid too much attention to them," she said. "I hope we can get to know them better soon."

One thing is certain, Yeo said: We shouldn't make too many assumptions about people's personality or health just because they write with which hand. And of course, we don't have to worry about the success rate of left-handed: after all (as of 20 15), five of our past seven American presidents were left-handed or left-handed.
