What is ambidexterity and how to develop it

Ambidexterity (lat. Ambi - "both" and dexter - "right") is an innate or training ability to control both hands equally, without prioritizing any of the hands, with the same speed and efficiency. Such people are usually called two-handed or double-armed.

Interesting facts about ambidexterity

Ambidextrous are not only people, but also animals.

If you can write equally well with both hands, then you are a great one, and only one percent of the total number of people have the same abilities.

According to experts, right-left and mixed-handedness do not necessarily determine people's ultimate preferences. Most people experience some level of cross-dominance — preferring one hand for certain tasks, even if it is not dominant — and there are even more subtle differences among those using both hands. Ambidekstras are those who can use both hands in the same way as right-handers use their right hand, and ambisinisters are those who use both hands as right-handers use their left (i.e. crooked and clumsily).

In contrast to right-handers, who show a strong dominance of the left hemisphere of the brain, the hemispheres of ambidextra are developed almost symmetrically.

Ambidextra most likely possess the LRRTM1 gene, which has been associated with schizophrenia. Research shows that most people with schizophrenia are ambidextrous or left-handed.

Ambidexters are worse than left-handers and right-handers at coping with various tasks, especially with arithmetic, memory problems and logical exercises, and that ambidextra have language problems and attention deficit disorder.

Ambidexterity has also been linked to an accelerated decrease in brain volume with aging.

Both-armed fighters have always been appreciated since ancient times. Modern contact sports are no exception. It is difficult for such an athlete to oppose something, since he is equally good at using both hands and can easily change stance and tactics.

The so-called Macedonian shooting, a method of firing a pair of pistols with both hands, has long been practiced by the special services of different countries during the training of employees.

Despite some disadvantages, the use of two hands can be beneficial not only in sports, but also in science, art and music. Among those who equally wield two hands are such famous personalities as Leonardo da Vinci, Nikola Tesla, Paul McCartney, Benjamin Franklin, Mark Knopfler and Keanu Reeves.

How to develop ambidexterity?

It has long been known that the nondominant hand is associated with the nondominant hemisphere of the brain. The right one with the left one is responsible for logic, and the left one with the right one is creative. Therefore, when you use your non-dominant hand as a working hand, both hemispheres are activated, this can lead to a change in thinking and an increase in creativity.

An easy way to develop ambdexterity

"Mirror Drawing". Put a blank sheet of paper on the table, take a pencil each. Draw at the same time with both hands mirror-symmetrical drawings, letters. When doing this exercise, you should feel relaxation of the eyes and hands, because when both hemispheres work at the same time, the efficiency of the whole brain improves.

  • The main thing is to show perseverance and maintain discipline. 20-40 minutes of writing and drawing every day. Plus various daily activities. First, we change the hand in one-handed actions: at first, you can simply put the other hand behind your back.
  • Then the exchange of roles in two-handed actions: if confusion arises, we stop and study the old habitual movements. Then we mirror them on the working hand.
  • When it turns out well, we alternate the supremacy of the hands daily.

The first time will be hard: uncomfortable, crooked, slow. It will get better and easier soon. Gradually, the speed of mastering new movements will no longer depend on the (now consciously chosen) leading hand.
