In an interview with Health Times, Xu Dongmei, deputy chief physician of the Department of Neurology of beijing ditan hospital, said that, in simple terms, the left brain dominates the activities of the right hemisphere, and is responsible for processing language, abstract thinking, logical reasoning, numerical operation and so on. Therefore, it is called "rational hemisphere"; People's right brain dominates the activities of the left hemisphere, and is responsible for dealing with image thinking such as spatial imagination, music and rhythm, which is called "artistic hemisphere".
Left-handed people are used to using their left hand, which helps to stimulate and develop their right brain, so their "artistic hemisphere" is more developed and their thinking ability in images will be better; Right-handed people are used to using their right hands, which helps to stimulate and develop the left brain, so their "rational hemisphere" is more developed and their logical thinking ability will be better.
Extended data:
Some parents will scold or even "beat the board" to help their children get rid of left-handedness, but Zheng Xiuli, a doctor of psychology at the Institute of Psychology, Chinese Academy of Sciences, said in an interview with Life Times that whether a child is left-handed can be seen at about two years old, and it is basically stereotyped at three or four years old. This is also a critical period for children's physical and mental development. If parents force their children to "change hands", it is equivalent to "driving ducks to the shelves", which often makes children feel frustrated and helpless, and easily leads to adverse consequences such as nervousness, emotional anxiety and inattention.
Zheng Xiuli suggested that parents should have a correct attitude and know that the evolution of the brain has its natural laws, and both left-handed and right-handed people have their own potential and bright future. If the child is willing, parents can encourage the child to exercise the hand he uses less, support the development of both hands, and make the right hand more skilled on the premise that the left hand is not stupid.
People's Network-Left-handed people are not necessarily smarter, because the left brain and the right brain have different division of labor.
