Medical Video: Parents Forcing Me To Be Right-Handed - Reflection
One in 10 people in the world is born with the left hand dominant or left-handed. So, what causes left-handed children from birth, and when can parents know whether their children are left-handed or not since they were still in the womb? Can ultrasound examinations help predict this? Check out the reviews here.
What makes left-handed children?
Experts believe that the cause of someone being left-handed comes from nerves in the spinal cord. Initially, many researchers thought the brain's motor cortex sent signals to the spinal cord to move hands and feet. However, a study from Ruhr University Bochum in Germany reported that the motor cortex of the brain had not even been connected to the spinal cord at 8 weeks' gestation.
In fact, babies can move their hands in the direction they prefer at that age. the tendency to use more of one side of the hand has been formed since the 8th week of pregnancy. Meanwhile, the habit of thumbing with one side of the hand appeared at week 13 based on ultrasound examination. In other words, the baby has started movement and can choose his favorite hand even before the brain begins to control his body movements.
This theory was concluded after the research teamobserve DNA sequences in the baby's spinal cordat the 8th to 12th week of pregnancy. They found that DNA sequences in nerve segments on the right and left side of the bone marrow control foot and hand movementsquite different.
"This is not impossible because many nerve fibers cross from one side to another at the boundary between the hindbrain and the spinal cord," explained Carolien de Kovel, lead author of the study and researcher at the Max Plank Institute for Psycholinguistics.The researcher concluded that this difference could be influenced by the environment, whichlater it will affect baby's growth.
Simply put, the development of left-handed hands has occurred since in the womb. Genetic factors and environmental exposure during pregnancy together play a role in making someone left-handed, de Kovel closes.
When can parents know their child is left-handed or not?
Even though the child has begun to show a tendency to use his "favorite" hand since he was still in his mother's stomach, this is not a determining factor whether the child will really be left-handed or not when he grows up.
Reporting from the Baby Center, most children begin to show the dominant hand around the age of 2 or 3 years. There are also those that have been seen since 18 months. Some children can even use both hands as actively until they are 5 or 6 years old.
If you want to know whether your baby is left-handed or not, you can find out by trying to give a toy and waiting for him to reach it. Try rolling the ball and see which hand will reach the ball first. Children will tend to use their dominant hands to reach for toys because they are more nimble and stronger.
Should left-handed children be taught to use their right hand?
Experts argue that parents do not need to force children to change their dominant hands if they are born left-handed. Coercion will frustrate and hinder the learning process because the nervous system and brain are not designed to do everything with the right hand.
What needs to be understood, left-handed hands is not a curse. Every child is a gift and gift for parents. Encourage children to be confident in their uniqueness and give children tools or instruments designed to be used by left-handed people. For example, left-handed scissors or left-handed guitars specifically.
When the child is big enough, give an understanding that even though he is different from his friends, it does not mean he is bad. Remind children that some of the strongest, smartest, or most accomplished people in the world are left-handed people. Tell left-handed figures that can build children's confidence.
Left-handed people are even known to have the ability to think creatively and critically beyond expectations, and this makes it easier for them later to solve problems either at school or at home. Usually left-handed children have better imagination, creativity, and emotional control than children who predominantly use their right hand.
