Our brain is like a walnut. It has two hemispheres. These two have different functions.
The left hemisphere specializes in analytical thought. It is responsible for dealing with "hard" facts such as abstractions, structure, discipline, rules, time sequences, mathematics, categorizing, logic, rationality, and deductive reasoning. It is also responsible for details, knowledge, definitions, planning, goals, words, productivity, efficiency, science, technology, stability, extroversion, physical activity, and the right side of the body. Left hemisphere ability is the predominant focus in school and society.*
The right hemisphere specializes in "softer" aspects than the left hemisphere. The right hemisphere is responsible for intuition, feelings, sensitivity, emotions, daydreaming, visualizing, creativity, color, spatial awareness, and first impressions. It is also responsible for rhythm, spontaneity, impulsiveness, the physical senses, risk-taking, flexibility and variety, learning by experience, relationships, mysticism, play and sports, introversion, humor, motor skills, and the left side of the body (the old belief that left-handed people are more creative does hold some scientific credence). The right hemisphere also has a holistic method of perception that is able to recognize patterns and similarities and combines those elements into new forms.*
I'm curious about what part I am dominant. So I tried a test in this link Right vs. Left Brain Creativity Test
The results show your brain dominance as being:
Left Brain | Right Brain |
55% | 45% |
You are more left-brained than right-brained. Your left brain controls the right side of your body. In addition to being known as left-brained, you are also known as a critical thinker who uses logic and sense to collect information. You are able to retain this information through the use of numbers, words, and symbols. You usually only see parts of the "whole" picture, but this is what guides you step-by-step in a logical manner to your conclusion. Concise words, numerical and written formulas and technological systems are often forms of expression for you. Some occupations usually held by a left-brained person include a lab scientist, banker, judge, lawyer, mathematician, librarian, and skating judge.*
