You’ve probably heard people describe themselves as ‘left-brained’ or ‘more in touch with the right side of their brain’. You may know that is someone implying that they are more rational or more creative like that but the complete idea of your left and right brain is really compelling. The left brain is logical, analytical, and aware of patterns. The right brain is creative, sensory, and aware of feelings. These two halves work together in your everyday life. For example, in music, the left brain recognizes lyrics, and the right brain can pick up on the tune. This is because the left brain works with words, and the right brain works with pictures. The left hemisphere is mostly in charge of listening, speaking, math, and memories. In contrast the right side manages visual abilities, like recognizing faces. It also deals with music, understanding meaning in what someone’s saying, and spatial abilities.
The idea of these two hemispheres originated in the 1960’s by a psychologist Roger W. Sperry. He experimented with the brain and learned that both sides have very different functions. Another fact that Sperry learned was that the left side of the brain controlled the right side of the body and vice versa.
Many people tend to have personality traits that more closely resemble one side or another. There are many tests you can take online to tell which side represents you better. The most popular one is this http://braintest.sommer-sommer.com/en/. I took it and these were the results. Feel free to share your results in the comments!
