Better Communication by Using All Your Brains
If you use your brain, you can communicate better, but what “brain” are you going to use? Why not use them all?
Standard understanding of the brain right now is that it is “triune,” with three parts – the reptilian, or primitive brain; the limbic brain; and the neocortex. Further, the neocortex is divided into two hemispheres, the right and the
left.
Reptilian
Briefly, the reptilian brain is responsible for keeping us alive and evolved millions of years ago. We share it with reptiles. This brain operates territorial defense and aggression, sex drive, and rudimentary life-maintaining systems such as breathing and heartbeat. It’s automatic. We have no control over it.
Example
When someone pushes you out of line in the movie theater, although it isn’t really life-threatening, our reptilian brain acts as if it were. It is always lurking there, ready to flare up and “protect” us. It’s responsible for a lot of fear we feel during the day.
Limbic
The limbic brain evolved next and we share it with mammals. It’s responsible for the look we see in the dog’s eyes, and the way horses attune to us. It gives us the parenting urge (reptilians abandon their young at birth), bonding, compassion, family-ties, and things like that.
Example
When the baby cries at night and you’d rather be sleeping, you get up. Why? Because those parental emotions are tugging at you.
Neocortex
The neocortex, or thinking brain was the last to evolve, and belongs exclusively to humans. It is divided into two halves, the left hemisphere (left-brain) and the right hemisphere (right-brain). They aren’t isolated or separate. They are divided by something called the corpus callosum, which allows us to switch from one to the other.
The corpus callosum is typically better developed in women. This is why women can generally move from talking about feelings to talking about thoughts more easily than men can, though of course there are exceptions.
You will either be left-brain dominant, or right-brain dominant, but you can develop both sides and the communication between them by developing your emotional intelligence. I have worked with many people who have developed both sides of their brain so they are very balanced between the two. However, under stress, you will always revert to your dominant mode.
Here is a website where you can take a free assessment to see which you are: www.susandunn.cc/assessments.htm.
Left-brain
The left-brain is verbal, sequential, linear, and logical. People who are left-brain dominant respond to word meanings (more than how it’s said), plan ahead and go by steps, recall people’s names, and speak with fewer gestures and less expression.
Right Brain
The right brain is visual, holistic, and random. People who are right-brain dominant process in varied order, respond to emotion and tone of voice (more than the actual meaning of the words spoken), are more impulsive, remember people’s faces (more than their names), and use more gestures and expressions.
Communication
This is how this helps with communication. The hemisphere that’s dominant affects how the person hears, learns, relates and problem-solves, as you can see.
Example
If you want to explain a project to a left-brained person, give them a step-by-step outline, with a timeline and accountability. Right-brained people prefer to be told what to do, but not how to do it. They’re adept at figuring out how. Right-brained people, being visual, prefer to see something like a mind-map – it gives them the points to be covered, but does not dictate the order.
Since right-brained people are more flexible, if you’re right-brained, you may need to accommodate to the left-brained people with whom you work. That’s just the way it works. Whatever it takes to get a project done, right?
Take the Test
Here’s a test to see if you understand the difference. Which “brain dominant” is talking in each of these examples, “right” or “left”?
