Dominance - Topic Summary
|
| Just as some people are left-handed or right-handed, have a dominant right or left eye, chances are they probably have a brain hemisphere as well. So what does it mean to be "left-brain" or "right-brain" dominant? What the heck does "left-brain" or "right-brain" mean in the first place? |
Despite the fact that both the left and right hemispheres of your brain work together, they are not exactly the same. Each side differs from the other slightly in its functions and processes. While no one is totally left-brained or totally right-brained, most people tend to favour their dominant side. Strangely, about 90 percent of humans in all societies, even prehistoric humans, are left-brain dominant. Why the left hemisphere should come to dominate is not clear, although scientists believe it is linked to the left hemisphere's large role in speech and motor tasks.
To find which side of your brain you favour, take the Dominance Test.
