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:

  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.

Success In Reaching Goals Is Determined By Mindset

Success In Reaching Goals Is Determined By Mindset

What do you think it takes to achieve your goals? Hard work? Lots of actions? While these are paramount to becoming successful in reaching our goals, neither of these are possible without a positive mindset.

As humans, we naturally tend to lean towards a negative outlook when it comes to our hopes and dreams. We are prone to believing that we have limitations either from within ourselves or from external forces keeping us from truly getting to where we want to be in life. Our tendency to think that we’ll “believe it when we see it” suggests that our mindsets are focused on our goals not really being attainable until they’ve been achieved. The problem with this is that this common mindset fuels our limiting beliefs and shows a lack of faith in ourselves.

The Success Mindset

Success in achieving our goals comes down to a ‘success mindset’. Successful mindsets are those focused on victory, based on positive mental attitudes, empowering inclinations and good habits. Acquiring a success mindset is the sure-fire way to dramatically increase your chance to achieve your goals.

The idea that achieving our goals comes down to our habits and actions is actually a typical type of mindset that misses a crucial point; that our mindset is, in fact, the determiner of our energy and what actions we take. A negative mindset will tend to create negative actions and similarly if we have a mindset that will only set into action once we see ‘proof’ that our goals are achievable, then the road will be much longer and arduous. This is why, instead of thinking “I’ll believe it when I see it”, a success mindset will think “I’ll see it when I believe it.”

The Placebo Effect and What It Shows Us About The Power of Mindset

The placebo effect is a perfect example of how mindset really can be powerful. In scientific trials, a group of participants were told they received medication that will heal an ailment but were actually given a sugar pill that does nothing (the placebo). Yet after the trial the participants believed it’s had a positive effect – sometimes even cured their ailment even though nothing has changed. This is the power of mindset.

How do we apply this to our goals? Well, when we set goals and dreams how often do we really believe they’ll come to fruition? Have absolute faith that they can be achieved? Have a complete unwavering expectation? Most of us don’t because we hold on to negative mindsets and limiting beliefs about ourselves that stop us from fully believing we are capable or that it’s at all possible. We tend to listen to the opinions of others despite them misaligning with our own or bow to societal pressures that make us believe we should think and act a certain way. There are many reasons why we possess these types of mindsets but a success mindset can be achieved.

How To Create a Success Mindset

People with success mindsets have a particular way of perceiving things. They have positive outlooks and are able to put faith fully in their ability to succeed. With that in mind, here are a few ways that can turn a negative mindset into a successful one.

1. A Success Mindset Comes From a Growth Mindset

How does a mindset even manifest itself? It comes from the way you talk to yourself in the privacy of your own head. Realising this will go a long way towards noticing how you speak to yourself and others around you. If it’s mainly negative language you use when you talk about your goals and aspirations then this is an example of a fixed mindset.

A negative mindset brings with it a huge number of limiting beliefs. It creates a fixed mindset – one that can’t see beyond it’s own limitations. A growth mindset sees these limitations and looks beyond them – it finds ways to overcome obstacles and believes that this will result in success. When you think of your goal, a fixed mindset may think “what if I fail?” A growth mindset would look at the same goal and think “failures happen but that doesn’t mean I won’t be successful.”

There’s a lot of power in changing your perspective.

2. Look For The Successes

It’s really important to get your mind focused on positive aspects of your goal. Finding inspiration through others can be really uplifting and keep you on track with developing your success mindset; reinforcing your belief that your dreams can be achieved. Find people that you can talk with about how they achieved their goals and seek out and surround yourself with positive people. This is crucial if you’re learning to develop a positive mindset.

3. Eliminate Negativity

You can come up against a lot of negativity sometimes either through other people or within yourself. Understanding that other people’s negative opinions are created through their own fears and limiting beliefs will go a long way in sustaining your success mindset. But for a lot of us, negative chatter can come from within and these usually manifest as negative words such as can’t, won’t, shouldn’t. Sometimes, when we think of how we’re going to achieve our goals, statements in our minds come out as negative absolutes: ‘It never works out for me’ or ‘I always fail.’

When you notice these coming up you need to turn them around with ‘It always works out for me!’ and ‘I never fail!’ The trick is to believe it no matter what’s happened in the past. Remember that every new day is a clean slate and for you to adjust your mindset.

4. Create a Vision

Envisioning your end goal and seeing it in your mind is an important trait of a success mindset. Allowing ourselves to imagine our success creates a powerful excitement that shouldn’t be underestimated. When our brain becomes excited at the thought of achieving our goals, we become more committed, work harder towards achieving it and more likely to do whatever it takes to make it happen.

If this involves creating a vision board that you can look at to remind yourself every day then go for it. Small techniques like this go a long way in sustaining your success mindset and shouldn’t be dismissed.

An Inspirational Story…

For centuries experts said that running a mile in under 4 minutes was humanly impossible. On the 6th May 1954, Rodger Bannister did just that. As part of his training, Bannister relentlessly visualised the achievement, believing he could accomplish what everyone said wasn’t possible…and he did it.

What’s more amazing is that, as soon as Bannister achieved the 4-minute mile, more and more people also achieved it. How was this possible after so many years of no one achieving it? Because in people’s minds it was suddenly possible – once people knew that it was achievable it created a mindset of success and now, after over fifty years since Bannister did the ‘impossible’, his record has been lowered by 17 seconds – the power of the success mindset!
