Your Brain Hemispheres

This chart illustrates that you are left-brained and to what extent.

Callahan's Right/Left Brain Tendency

There are two sides of your brain known as hemispheres. Your left hemisphere controls the right side of your body and deals with logical thought and language. Your right hemisphere controls the left side of your body. It handles abstract thought and spatial orientation.

Neuropsychologist Roger W. Sperry developed the right brain – left brain theory in 1960. He believed that the human brain is right or left side dominant and that each side of the brain controls different types of thinking. Some individuals utilize both sides of their brains equally (all use both to some degree) but most people have a greater tendency to think in a certain way.

The majority of people are left brain dominant. Although the typical school environment in modern times tends to favor left brain thinkers with expectations of logical thought and practical action, right brain thinkers who tend to be more imaginative and "outside the box" are equally valuable. Interestingly, right brain dominant people are often left-handed (since each hemisphere controls the opposite side's hand) which coincides with right brain dominant people being less common (as left-handed people are less common).

Understanding the right brain – left brain theory helps you understand yourself better. It improves your ability to study, learn and process information. It also informs you about the reasons why you prefer certain activities or have certain interests.

"Personality is that which is most intimate to me—that by which I must act out my life. It is that by which I belong to man, that by which I am able to reach after God; and He has given to me this pearl of great price. It is an immortal treasure; it is mine, it is His, and no man shall pluck it out of His hand." — Hugh Reginald Haweis
