Left-handedness is not a whim, but a feature of the brain, inherent in nature. According to statistics, about 10-15% of the population planets give preference to the left hand in everyday affairs. However, many parents still wonder: “Is it possible to retrain a left-hander to make it easier for him in a right-handed world?” Disputes on this topic have not subsided for decades - from grandmothers' advice to “take the spoon to the right!” to scientific research on the impact of retraining on the psyche.
In this article we will look at myths and facts about left-handedness, we’ll tell you what happens to the brain when the dominant hand is forced to change, and we’ll give practical recommendations for parents and teachers. You will learn in which cases retraining is really justified (spoiler: there are almost none), and when it can be harmful. We'll also look at how to adapt being left-handed to a right-handed world. no stress - from choosing school supplies to learning to drive.
Important: this article does not replace consultation with a neurologist or psychologist. If you have doubts about your child’s development, be sure to consult a specialist.
Left-handedness: biological norm or deviation?
Until the mid-20th century, left-handedness was often considered pathology or even a sign of mental retardation. In some countries, left-handed children were forcibly retrained and, in extreme cases, even punished for using the “wrong” hand. Fortunately, today science has refuted these myths: left-handedness is variant of the norm, due to the characteristics of the brain.
Research shows that left-handed and right-handed people are organized differently. interhemispheric asymmetry. For most right-handers, speech centers are located in left hemisphere, and 30% of left-handers have right or distributed between both. This doesn't mean that left-handers are "different" - just that their brains work differently, which sometimes gives them advantages in creative and spatial tasks.
- 🧠 Genetic predisposition: if one of the parents is left-handed, the probability of having a left-handed child increases to 20-25%.
- 🔬 Effect of testosterone: Some scientists associate left-handedness with high levels of this hormone during pregnancy.
- 🎨 Creativity: among left-handers there are more musicians, artists and architects - perhaps due to the peculiarities of spatial thinking.
However, there is also false left-handedness - when a child begins to use his left hand due to an injury to the right or imitation. In this case, temporary retraining may be justified, but only after consultation with pediatric neurologist.
What happens to the brain when retraining to be left-handed?
Forcibly retraining a left-handed person is stress for the nervous system. The child’s brain is already “tuned” to using the left hand as the leading one, and a forced change can lead to hemispheric conflict. The consequences depend on the age, temperament of the child and the method of retraining, but most often they manifest themselves as follows:
| Possible consequences | Manifestations | Effect duration |
|---|---|---|
| Stuttering and speech disorders | Stuttering, repetition of syllables, difficulties with pronunciation | From several months to permanent defect |
| Problems with coordination | Clumsiness, difficulty with fine motor skills (tying shoelaces, writing) | May persist into adulthood |
| Emotional disorders | Increased anxiety, aggression, low self-esteem | Depends on psychological support |
| Deterioration in academic performance | Difficulties with reading, writing, remembering information | Most often temporary, but can affect motivation to study |
Critical Warning: In children under 5 years of age, retraining to be left-handed may cause neurological problems, including tics and enuresis. This is due to the fact that at an early age the brain is especially plastic, and interference with the natural processes of formation of the dominant hand is fraught with disruptions.
Interesting fact: among the famous left-handers - Leonardo da Vinci, Albert Einstein, Bill Gates and Lady Gaga. It is difficult to imagine that their genius could have been revealed if they had been retrained in childhood.
Why do some left-handers become ambidextrous themselves?
A small percentage of left-handers develop the ability to use both hands equally well with age. It occurs naturally, without coercion, and is usually associated with professional activities (for example, surgeons or musicians).
When is retraining a left-hander justified? Exceptions to the rules
In 99% of cases, retrain a left-handed person no need. However, there are rare situations when temporary correction may be recommended by specialists:
- 🩺 Medical indications: if left-handedness is caused by injury to the right hemisphere or a neurological disease (for example, cerebral palsy). The decision is made neurologist after diagnosis.
- ⚡ Emergency adaptation: In some professions (pilots, military), equipment is designed for right-handed people. In this case, an adult left-hander can learn skills with his right hand, but this does not mean complete relearning.
- 🎻 Playing musical instruments: Some instruments (like the violin) have historically been designed for right-handed people. However, today there are left-handed models or adapters.
Even in these cases, we are not talking about complete retraining, but about development of ambidexterity - ability to use both hands. Important: any changes must be gradually and under the supervision of a specialist.
⚠️ Attention! If a teacher at school or kindergarten insists on retraining left-handers, this is a violation SanPiN 2.4.1.3049-13 (clause 4.12), which stipulates respect for the individual characteristics of the child. Parents have the right to write a statement addressed to the head with a demand to stop such practices.
How to adapt a left-handed person to a right-handed world: practical advice
Instead of retraining your child, it is better to help him function comfortably in a world where most things are designed for right-handed people. Here specific recommendations for different areas of life:
Make sure your school allows you to write with your left hand|Buy left-handed scissors and sharpeners|Teach your child to hold a pen correctly (tilting the sheet to the left)|Show how to use “right-handed” objects with the left hand (for example, opening cans)|Encourage activities where left-handedness is an advantage (tennis, fencing)-->
School supplies:
- ✏️ Handles with rubber pads - Prevent finger fatigue.
- 📝 Notebooks with slanted rulers — help to avoid “arrivals” when writing.
- ✂️ Left-handed scissors (brands Fiskars, Maped) - the blades are mirrored.
Household items:
- 🪑 Position the table so that the light falls right - this reduces the shadow of the hand when writing.
- 🔑 Hang hooks and shelves in the hallway at the level of the child’s left hand.
- 🎮 For computer games, configure the control keys for the left hand (in most games this can be done in the settings).
Sports and hobbies: Some sports are easier for left-handed people:
- 🎾 Tennis - Left-handers often have an advantage due to unexpected blows.
- ⚔️ Fencing — left-handed fencers beat right-handed fencers in 60% of cases.
- 🎨 Drawing — left-handed artists are more likely to show originality in composition.
If a left-handed child is learning to play the guitar, do not immediately buy a left-handed instrument. Many famous guitarists (like Jimi Hendrix) played standard guitars simply with their strings turned upside down.
Left-handedness and driving: what you need to know?
One of the most common questions from parents of left-handed teenagers: “Will they be able to drive normally?” Answer: yes, no problem. Modern cars are symmetrical and the pedal placement is the same for everyone. However, there are several nuances:
What may be inconvenient:
- 🚗 Gear lever - is on the right, but the left-hander quickly adapts.
- 🎛️ Steering wheel - some left-handers prefer to hold it “clockwise” (left hand at 7-8 o’clock, right hand at 4-5).
- 🅿️ Handbrake — reaches with his right hand, but this is a matter of habit.
Advantages of left-handed driving:
- ⚡ React faster to obstacles on the right (according to statistics IIHS, left-handers are less likely to get into accidents when changing lanes).
- 🔄 It is easier to park in reverse, as they better assess the space on the left.
If your left-handed child is going to take a driving course, notify the instructor in advance. An experienced teacher will adjust teaching methods, for example:
- Will focus on mirrors (it’s easier for lefties to control the left).
- He will show you how it is more convenient to change gears with your left hand (if this does not interfere with safety).
⚠️ Attention! In some driving schools there is still a myth that left-handed people “don’t feel the car.” This is not true - according to data traffic police, the percentage of accidents among left-handers is no higher than among right-handers. If an instructor refuses to accept a left-handed person for training, ask for a written refusal - this is discrimination.
Myths about left-handedness: what the “experts” say and where they go wrong
There are many misconceptions surrounding left-handedness, which are often passed off as “folk wisdom.” Let's look at the most common ones:
Myth 1: “Left-handers live less than right-handers”
🔹 Reality: This statement is based on an outdated 1991 study that did not take into account external factors (for example, left-handers are more likely to participate in extreme sports). Modern data (Journal of Epidemiology, 2020) refute this connection.
Myth 2: “Left-handers are more creative, but less logical”
🔹 Reality: Left-handers are no worse at math and programming. Among them are Nobel Prize winners in physics and creators of programming languages (for example, Guido van Rossum, author Python).
Myth 3: “Left-handedness can be determined by which foot a child kicks the ball with”
🔹 Reality: Lead leg and lead arm may not be aligned. To accurately determine your dominant hand, use the test with intertwined fingers (if the thumb of the left hand is on top, most likely the child is left-handed).
Myth 4: “In the USSR, all left-handers were retrained, and it’s no big deal”
🔹 Reality: Mass retraining in Soviet schools led to an increase in neurological disorders in children. Today it is recognized medical error, and in developed countries left-handedness is protected by anti-discrimination laws.
Left-handedness is not a diagnosis or a disability. This is the same norm as eye color or blood type. The task of parents is to help the child reach his potential, and not to try to “fix” him.
What to do if the child has already begun to be retrained?
If you understand that a child is being forcibly re-educated (at school, kindergarten, or even at home on the advice of relatives), act immediately:
- Stop any attempts at correction. — return to the child the ability to use his left hand without restrictions.
- Contact a child psychologist - it will help relieve stress and restore self-esteem.
- Perform a neurological examination - to eliminate consequences (tics, stuttering, sleep disturbances).
- Talk to teachers — explain that retraining is prohibited by sanitary standards.
If the child is already used to writing with his right hand, but feels discomfort:
- 📝 Offer him gradually return to the left hand, starting with drawing and sculpting.
- 🧩 Use games to develop fine motor skills of the left hand (constructors, puzzles).
- 💬 Discuss his feelings - many children are ashamed to admit that they are uncomfortable.
Restoring natural left-handedness can take from several months to a year, but the main thing is don't push per child. According to Association of Children's Neurologists of Russia, in 80% of cases, children successfully return to using the dominant hand without consequences if relearning lasted less than 2 years.
FAQ: Answers to frequently asked questions about left-handedness
Is it possible to identify a left-handed person before the age of one?
No, the leading hand is formed to 3-5 years. Until then, the child can use both hands equally. Tests for left-handedness before 2 years of age are not informative.
Is it true that left-handers are more likely to become geniuses?
There is no direct connection, but left-handers are indeed more common among people with IQs above 140 (according to Mensa International). This is due to the characteristics of the brain, and not to left-handedness itself.
What if you are forced to write with your right hand at school?
Write a statement addressed to the director with a link to SanPiN 2.4.1.3049-13 (clause 4.12) and Convention on the Rights of the Child (v. 29). If the problem is not resolved, please contact Rosobrnadzor.
Is it possible to learn to write equally well with both hands?
Yes, but it requires a lot of training. Complete ambidexterity (equal use of the hands) occurs in less than 1% of people and is more often congenital rather than acquired.
Are there special keyboards for left-handers?
Yes, for example, Maltron or Kinesis Advantage — ergonomic keyboards with divided blocks. You can also reassign keys in the OS settings (in Windows: Settings → Devices → Keyboard → Advanced options).
