Why Introverts Are Introverts? Because Their Brains Are Different

Why Introverts Are Introverts? Because Their Brains Are Different

You prefer to curl up and read a book by yourself over going to a flashy social event. You like the company of one close friend rather than a group of many rowdy people. Once more you prefer to stay on the safe side than take risks. Does this sound familiar? If so, then you are probably an introvert. You may already know this but what you may not be aware of is that there are physical differences in your brain that make you prefer quiet activities over those that are highly energized.

Carl Jung’s studies

It was Carl Jung who in the 1920s coined the terms introvert and extrovert. He did so to describe contrasting personality types and to explain why different people were energized in distinct ways. He hypothesized that extroverts gained their energy from their social interactions and eternal environments and tended to feel uncomfortable and anxious when they found themselves alone.

Introverts, on the other hand, Jung explained, are able to replenish their energy levels when they are in quiet environments. Unlike extroverts they find socializing and busy environments overstimulating and too demanding.

Dr. Laney clarifies in her book, The Hidden Gifts of the Introverted Child that “introversion and extroversion are not black and white. No one is completely one way or another – we all must function at times on either  side of the continuum”.

Introversion and extroversion are at the opposite ends of the same spectrum. Everybody moves up and down the spectrum depending on external and internal factors, however, a person tends to prefer one personality type over the other.

The Dopamine difference

A major difference between the brains of introverts and extroverts is the way they react to the neurotransmitter dopamine.

Dopamine is a chemical that is released in the brain. It gives a person their motivation to achieve external goals and receive external rewards. For example, dopamine may motivate an individual to earn more money, increase their circle of friends, attract a good looking partner or advance to a higher role at work. When dopamine is released all of us become more alert to our surroundings, more talkative and more motivated to undertake activities that may be perceived as risky.

Introverts and extroverts have equal amounts of dopamine in their brains, however, the difference between these two categories of people is the activity of the dopamine reward network. The dopamine reward network is more active and dynamic in the brains of extroverts as Scott Barry Kaufman, the Scientific Director of The Imagination Institute says. When an extrovert anticipates a social event, for example, they feel good and energized, whereas the introvert will feel overstimulated.

Acetylcholine and Introverts

Christine Fonseca writes in her book Quiet Kids: Help your introverted child succeed in an extroverted world that introverts prefer to rely on a different neurotransmitter called acetylcholine.

Acetylcholine is related to pleasure, just like dopamine, however acetylcholine makes a person feel good when they turn inward. It gives a person the skill to reflect and focus solely on an individual task for an extended period of time. As it is simpler to turn inwards when there is limited external stimulation, introverts opt for a calm environment.

Introverts prefer one side of the nervous system over the other

The nervous system is divided into two distinct parts: there is the sympathetic side which is related to the “fight, fright, or flight” response; and the parasympathetic side. The parasympathetic side allows us to rest and digest.

When the sympathetic side is stimulated the body prepares for action; adrenaline is released, glucose energizes the muscles and the amount of oxygen in the body increases. The thinking mechanisms in the brain are put on hold. Dopamine increases alertness in the rear of the brain.

When the parasympathetic side of the brain is in gear; muscles relax, energy is stored and food is metabolized. Blood flow and alertness in the front of the brain increase as acetylcholine is released.

Although extroverts and introverts use both sides of the nervous system, various times introverts tend to prefer to use the parasympathetic side. This allows introverts to be calm and to act in a slow and measured way.

Why introverts tend to overthink

When information from the external world is received by an extroverts brain it travels via a short pathway that goes through the areas of the brain where touch, taste, sound and sight are processed.

When introverts receive stimulus from the outside world the pathway that the information travels through is a lot longer. The information goes through many areas of the brain including:

Advertising

  1. The right front insular,
  2. Broca’s area,
  3. The right and left front lobes and,
  4. The left hippocampus.

The right front insular is an area involved with empathy, emotional thought and self-reflection. The Broca’s area activates self-talk and plans speech. The right and left front lobs, plan and select ideas and actions. The left hippocampus decides what things are personal and places them in long-term memories.

The long journey that the information takes when an introvert receives stimulus from the external world is the reason that introverts take longer to speak, react and make decisions.

Introverts have more gray matter in the front of their brains

study published in the Journal of Neuroscience discovered that introverts have larger, thicker gray matter in their prefrontal cortex. The prefrontal cortex is the place in the brain that is linked to abstract thought and decision-making. Extroverts, on the other hand, have thinner gram matter in the same area.

What does this mean? It means that introverts devote more of their energy and resources to abstract thought while extroverts have the propensity to live in the moment.

Summation

Things may now make more sense to you, as an introvert. You can now understand that there are physical differences in your brain that make you prefer peaceful activities and self-reflection over highly energized situations.

How to Be True to Yourself and Live the Life You Want

How to Be True to Yourself and Live the Life You Want

We live in a world that constantly tells us what to do, how to act, what to be. Knowing how to be true to yourself and live the life you want can be a challenge.

When someone asks how we are, we assume that the person does not mean the question sincerely, for it would lead to an in depth conversation. So telling them that you are good or fine, even if you’re not, is the usual answer.

In an ideal world, we would stop and truly listen. We wouldn’t be afraid to be ourselves. Instead, when we answer about how we are doing, our mask, the persona we show the world, tightens. Sometimes even more so than it might have been before. Eventually, it becomes hard to take off, even when you’re alone.

Imagine a world where we asked how someone was doing and they really told us. Imagine a world where there were no masks, only transparency when we talked to one another.

If you want to live in a world that celebrates who you are, mistakes and all, take off the mask. It doesn’t mean you have to be positive or fine all the time.

According to a Danish psychologist, Svend Brinkman, we expect each other to be happy and fine every second, and we expect it of ourselves. And that “has a dark side.”[1] Positive psychology can have its perks but not at the expense at hiding how you truly feel in order to remain seemingly positive to others.

No one can feel positive all the time and yet, that is what our culture teaches us to embrace. We have to unlearn this. That said, telling others you are ‘“fine”’ all the time is actually detrimental to your wellbeing, because it stops you from being assertive, from being authentic or your truest self.

When you acknowledge a feeling, it leads you to the problem that’s causing that feeling; and once you identify the problem, you can find a solution to it. When you hide that feeling, you stuff it way down so no one can help you.You can’t even help yourself.

Feelings are there for one reason: to be felt. That doesn’t mean you have to act on that feeling. It just means that you start the process of problem solving so you can live the life you want.

1. Embrace Your Vulnerability

When you are your true self, you can better self-advocate or stand up for what you need. Your self-expression matters, and you should value your voice. It’s okay to need things, it’s okay to speak up, and it’s okay not to be okay.

Telling someone you are simply “fine” when you are not, does your story and your journey a great disservice. Being true to yourself entails embracing all aspects of your existence.

When you bring your whole self to the table, there is nothing that you can’t beat. Here’re 7 benefits of being vulnerable you should learn.

Can you take off the mask? This is the toughest thing anyone can do. We have learned to wait until we are safe before we start to be authentic.

In relationships especially, this can be hard. Some people avoid vulnerability at any cost. And in our relationship with ourselves, we can look in the mirror and immediately put on the mask.

It all starts with your story. You have been on your own unique journey. That journey has led you here, to the person you are today. You have to be unafraid, and embrace all aspects of that journey.

You should seek to thrive, not just survive. That means you do not have to compete or compare yourself with anyone.

Authenticity means you are enough. It’s enough to be who you are to get what you want.

What if for the first time ever, you were real? What if you said what you wanted to say, did what you wanted to do, and didn’t apologize for it?

You were assertive, forthcoming in your opinions or actions to stand for what is right for you, (rather than being passive or aggressive) in doing so. You didn’t let things get to you. You knew you had something special to offer.

That’s where we all should be.

So, answer me this:

How are you, really?

And know that no matter the answer, you should still be accepted.

Bravery is in the understanding that you still may not be accepted for your truth.

Bravery is knowing you matter even when others say that you do not.

Bravery is believing in yourself when all evidence counters doing so (i.e. past failures or losses)

Bravery is in being vulnerable while knowing vulnerability is a sign of strength.

It’s taking control.

2. Choose Your Attitude in Adversity

You can take control of your destiny and live the life you want by being true to yourself. You can start anytime. You can start today.

You can start with one day at a time, just facing what happens that day. Most of us get overwhelmed when faced with the prospect of a big change. Even if the only thing we change is our attitude.

In one instant, you can become a different person with a change of attitude. When you take control of your attitude, you become able to better understand what is around you. This allows you to move forward.

Originally, you may have had a life plan. It could have started when you were little; you were hoping to become a mermaid, doctor, astronaut or all three when you grew up. You were hoping to be someone. You were hoping to be remembered.

You can still dream those dreams, but eventually reality sets in. Obstacles and struggles arise. You set on a different path when the last one didn’t work out. You think of all the “shoulds” in your life in living the life you want. You should be doing this…should be doing that…

Clayton Barbeau, psychologist, coined the term “shoulding yourself.’[2] When we are set on one path and find ourselves doing something different. It becomes all the things you should be doing rather than seeing the opportunities right in front of you.

But in all this disarray, did you lose sight of the real you?

It may be in our perceived failures and blunders that we lose sight of who we are, because we try to maintain position and status.

In being who we really are and achieving what we really want, we need to be resilient: How to Build Resilience to Face What Life Throws at You

It means that we do not see all possibilities of what might happen, but must trust ourselves to begin again, and continue to build the life we want. In the face of adversity, you must choose your attitude.

Can attitude overcome adversity? It certainly helps. While seeking to be true to yourself and live the life you want, you will have to face a fact:

Change will happen.

Whether that change is good or bad is unique to each person and their perspective.

You might have to start over, once, twice, a few times. It doesn’t mean that everything will be okay, but that you will be okay. What remains or should remain is the true you. When you’ve lost sight of that, you’ve lost sight of everything.

Advertising

And then, you rebuild. Moment after moment, day after day. We all have a choice, and in this moment, that matters.

You can choose to have a positive attitude, seeing the silver lining in each situation and, where there is none, the potential for one. Maybe that silver lining is you and what you will do with the situation. How will you use it for something good?

That’s how you can tap into yourself and your power. Sometimes it happens by accident, sometimes on purpose. It can happen when we aren’t even looking for it, or it can be your only focus. Everyone gets there differently.

You can rise, or you can remain. Your choice.

When the worst happens, you can rely on your authenticity to pull you through. That’s because Self Advocacy, speaking up to let others know what you need, is part of finding the real you.

There is nothing wrong with asking for help. Or sometimes, helping others can help us deal with the pain of a hurtful situation. You decide how you’re going to help others, and suddenly, you become your best self.

3. Do What Makes You Happy When No One’s Looking

Being the best version of you has nothing to do with your success or your status. It has everything to do with your Character, what you do when no one’s looking.

In order to create the life you want, you have to be the person you want to be. Faking it till you make it is just a way to white knuckle it through your journey. You have the fire inside of you to make things right, to put the pieces together, to live authentically. And Character is how you get there.

If you fall down and you help another up while you’re down there, it’s like you rise twice.

Along with attitude, your character is about the choices you make rather than what happens to you.

Yes, it’s about doing the right thing even when obstacles seem insurmountable.  It’s about using that mountain you’ve been given to show others it can be moved.  It’s about being unapologetically you, taking control, choosing your attitude in adversity and being the best version of you to create the life you want.

How do you know what you really want? Is it truly status or success?

Unfortunately, these things do not always bring happiness. And aspects of our image or “performance driven existence” may not achieve satisfaction. Materialism is part of our refusal to accept ourselves as enough. All the things we use to repress our true selves are about being enough.

“Enoughness” is what we truly seek, but ego gets in the way.

Advertising

Ego is the perception of self as outer worth. It’s not REAL self worth.

Ego represses our true self with a new self— the self of chasing ‘“Am I ever enough?”’ questions. And instead of filling our true selves with self-love and acceptance, when we “should ourselves” and chase “enoughness,” we feed the ego or our image.

It’s important to realize YOU ARE ENOUGH, without all the material trappings.

Stanford psychologist Meagan O’Reilly describes the damage of not thinking we are enough. One of her tactics for combating this is to complete the sentence,[3]

“If I believed I were already enough, I’d ____”

What would you do if you felt you were enough?

By believing you are enough, you can live the life you want.

So many fake it to try to get there, and they end up losing themselves when they lose more and more touch with their Authenticity.

Final Thoughts

By being yourself, you are being brave. By acknowledging all you can be, you tell the universe that you can until you believe it too. The steps are easy, and you are worth it. All of it is about the purpose you are leading and the passion that is your fuel.

Being true to yourself is all about mastering how to live life authentically rather than faking or forcing it. Having the life you want (and deserve) is about being trusting in yourself and the purpose you are living for. Both need passion behind it, fueling it each second, or you will experience burn out.

When you are authentic, you can call the road you walk your own. When you live your life for you and not just the results of all your actions (faking it till you make it), you can let go of what you don’t need. This clarifies and pushes purpose to you, living for something that is greater than you.

You will find that making decisions based on what will actually achieve your goals, will help you attain the life you want, and your success with each step, will allow you to enjoy the process. Good luck!
