Left-handers see the world differently – brain activity changes perception

Scientists at the University of Birmingham have found that left-handed people have a different worldview overall. The reasons for this lie in the two hemispheres of the brain that produce a different picture.  The scientists have made clear the differences in perception between right-handed and left-handed people. This is how right-handed people judge with their right brain to see the big picture. But when details are looked at from it, the left hemisphere of the brain is activated.

differences in use

For left-handed people it is exactly the opposite. According to the researchers, not only perception but also other activities such as speech or reading function are dependent on this fact. 95 percent of right-handers use the left hemisphere for language processes, but only 70 percent of left-handers.

Different hemispheres of the brain

Our brain consists of two sides – the left and right hemispheres. In the course of development from  toddler  to adult, these cerebral hemispheres specialize more and more and take on different tasks.

  • The  left hemisphere of the brain  specializes in logical thinking, it also controls the perception of detail and is the seat of the language center.
  • The  right hemisphere of the brain  is responsible for creativity and seeing the big picture. She thinks holistically and intuitively and also controls perceptions, emotions and imagination.

In left-handed people, the right, creative hemisphere is more developed and therefore more dominant. This is probably why left-handers are more often found in creative professions.

Left-handedness is not a flaw

Left-handers – Estimated to be at least ten percent of the total population. Thank God left-handed people no longer have to defend themselves against being retrained to use the right hand and being disadvantaged at work. Nevertheless, there are always difficulties for left-handers in everyday life. If you don’t believe it, if you are right-handed, you should try opening a can with your left hand, write with your left hand, or simply cut with scissors with your left hand. It’s just not that easy “with the left”.

Do not retrain left-handers!

Left-handedness is just as good as right-handedness – you can’t teach left-handers that early and often enough. Left-handed people begin to grasp everything with their left hand when they are young. It is important for parents not to influence the preferred use of a hand right from the start.

Reeducating a left-handed person to use the right hand can have serious consequences for the child: Problems at school such as difficulty concentrating, reading and spelling difficulties, even speech disorders or bedwetting have been described. It becomes particularly critical when a child stutters or is even hyperactive.

The reason:  If a left-handed child is forced to always use the right hand, the dominant right hemisphere is constantly undertaxed and the weaker left overtaxed. The consequences are serious and can negatively affect your whole life. Consequential damage such as inferiority complexes and psychosomatic complaints are inevitable.

Risk of left-handedness?

Researchers have also concluded that left-handers are more prone to  allergies , autoimmune diseases,  depression , drug addiction,  epilepsyschizophrenia ,  and  sleep disorders  . Other researchers assume that left-handers also have poorer spatial skills and are therefore more prone to accidents. However, the study published in the scientific journal The Lancet has dispelled a prejudice: left-handed people do not die earlier.

Small test

Please clap your hands before you read on.

Now observe which hand is on your bottom. As a rule, when clapping, left-handed people clasp their left hand on top of their resting right hand, while right-handed people hold their hands the other way around.

Known lefties

Left-handers are in good company. This is also shown by the following list of prominent left-handers: Mahatma Gandhi, Bill Clinton, Bill Gates, Marylin Monroe, Napoleon Bonaparte, Julius Caesar, Paul McCartney, Karl Lagerfeld, Sir Peter Ustinov, Martina Navratilova, Albert Einstein, Albert Schweitzer, Marie Curie, Isaac Newton.
