Which side controls more of your brain?

What is Brain Hemisphericity

Hemisphericity refers to the idea that people may rely on a preferred mode of cognitive processing, which is linked to activity on the part of the left or right cerebral hemispheres. Four methods have been used in hemisphereicity research: lateral eye-movements, electrophysiological measures, questionnaires, and cognitive tests.


According to the left-brain, right-brain dominance theory, the right side of the brain is best at expressive and creative tasks. Some of the abilities popularly associated with the right side of the brain include:

  • Recognizing faces
  • Expressing emotions
  • Music
  • Reading emotions
  • Color
  • Images
  • Intuition
  • Creativity

The left-side of the brain is considered to be adept at tasks that involve logic, language, and analytical thinking. The left-brain is described as being better at:

  • Language

I took 3 different tests myself to figure out what side i used most and I received scores of 66.67% on one, 50% exactly on another, and 57.89% on the last. All Left side oriented except the 50% because that one was even. The average of these is 58.19% for left side, which I can agree with. I am a very analytical and logical thinker but I think I can be creative as well sometimes.
