Have you heard the theory claiming that individuals are either “right brain dominant” or “left brain dominant”?
Are you straight-forward thinking, goal-oriented, and logical? Or are you creative, free-spirited, and have the ability to always think outside the box?
There is well known theory in popular psychology claiming that if you fit better in the first description,you are ‘left-brain dominant’, and ‘right-brain dominant” if you are often described as the latter. According to this hypothesis, the left brain is specifically responsible for logical reasoning, and the right for creative outputs; further claiming that by exercising one or the other hemispheres, your brain creates connections that slowly can alter your personality and abilities in an area.
well, thereb is no evidence that this theory is true.
Recent studies debunked the myth and found that different skill asserts do not correspound to any given hemispheres of the brain.
Although each individual obviously has a unique personality, this cannot be accurately credited towards one side of the brain being more dominant than the other.
In the 1940s, scientists and doctors conducted a study testing the right/left-brained theory that involved the surgical removal of the corpus callosum (a bundle of innumerable nerve fibers connecting the two hemispheres of the cerebrum) in patients with epilepsy.
After the procedure, patients saw a significant reduction in their seizures and seemed to have no change in intellectual and emotional functioning. However, the patients’ follow-ups revealed disruptions in both hemispheres of the brain in regards to perception and cognition that deteriorated into learning deficits, showing how the brain may not have specific designated regions for logical thinking and creativity, but rather functions as a unit in order to build certain skills.
