The most popular theory argues that personality is mainly influenced by the two hemispheres of the brain. Experts believe that the dominance of the left hemisphere makes the person more reasonable, with increased verbal skills and analytical thinking, while the dominance of the right hemisphere leads to increased intuition, perception and artistic tendencies.
A deeper understanding of the mechanisms and brain function specifies the way in which a person interacts with his environment, says eminent psychologist Steven Kosslyn. In collaboration with Wayne Miller, he developed the theory that the interaction of the top and bottom brain systems is what determines the personality.
“The top part plans and executes, while the bottom classifies and interprets information about the world that we receive,” say the two authors of the research. The two systems communicate and cooperate, but eventually the top part of the brain is the one that uses the information.
“In each person, the degree to which each system prevails in daily operations is different,” the researchers explain. The foundations of the theory of knowledge models depend on how much the person relies on one, both or none of the two systems. This model determines how we react to the events around us and how we interact and connect with people.
Individuals who use the abilities of both systems easily adapt to the circumstances and have the ability to plan effectively.
Those who use more the bottom brain have insight and can better interpret their experiences, but are not able to take initiatives for complex tasks.
When there the top system is more developed, the person is extremely creative but has no adaptation capacity.
Finally, people who do not rely on any of the two systems seem to get “lost” in the facts and the requests of those around them and are quite easily affected by the environment.
