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.

How to Spend More Quality Time with Your Partner

How to Spend More Quality Time with Your Partner

You see your partner every single day. They are the first person you talk to in the morning and the last person you kiss goodnight.

But does seeing each other day in and day out equal a healthy relationship? Not necessarily.

Spending quality time with your partner is the best way to ensure your relationship stays healthy and strong. This means going above and beyond sitting together while you watch Netflix or going out for the occasional dinner. You deserve more from your relationship – and so does your spouse!

What does quality time mean? It means spending time with your spouse without interruption. It’s a chance for you to come together and talk. Communication will build emotional intimacy and trust.

Quality time is also about expressing love in a physical way. Not sex, necessarily (but that’s great, too!) but through hand-holding, cuddling, caressing, and tickling. Studies show that these displays of affection will boost partner satisfaction.[1]

So how do you spend quality time with your partner? Here are 13 relationship tips on making the most out of your time with your partner.

1. Recognize the Signs

If you want a healthy relationship, you have to learn how to recognize the signs that you need to spend more quality time together.

Some telltale signs include:

  • You’re always on your phones.
  • You value friendships or hobbies over quality time with your spouse.
  • You aren’t together during important events.
  • You are arguing more often or lack connection.
  • You don’t make plans or date nights.
  • You’re not happy.

If you are experiencing any of these relationship symptoms, know that quality time together can reverse the negative effects of the signs above.

2. Try New Things Together

Have you ever wanted to learn how to play an instrument or speak another language? How about skydive or ballroom dance?

Instead of viewing these as solo hobbies and interests, why not involve your partner?

Trying new activities together builds healthy relationships because it encourages spouses to rely on one another for emotional and physical support.

Shared hobbies also promote marital friendship, and the Journal of Happiness Studies found that marital satisfaction was twice as high for couples who viewed each other as best friends.[2]

3. Schedule in Tech-Free Time

Your phone is a great way to listen to music, watch videos, and keep up-to-date with friends and family. But is your phone good for your relationship?

Many couples phone snub, or ‘phub’, one another. Studies show that phubbing can lower relationship satisfaction and increase one’s chances of depression.[3]

Reduce those chances by removing distractions when spending quality time together and showing your partner they have your full attention.

4. Hit the Gym as a Couple

One way you can spend more time together as a couple is by becoming workout partners. Studies show that couples are more likely to stay with their exercise routine if they work out together.[4] Couples also work out harder than they would solo. One study found that 95 percent of couples who work out together maintained weight loss compares to the 66 percent of singles who did.[5]

Join a gym, do at-home couples’ workouts, try couples yoga, hit the hiking trails, or get your bikes out. No matter which way you choose to exercise, these healthy activities can promote a healthy relationship.

5. Cook Meals Together

Pop open a bottle of wine or put some romantic music on while you get busy – in the kitchen, of course!

One of the best relationship tips for spending quality time together when you both have busy schedules is to cook meals together.[6]

Spice things up and try and prepare a four-course meal or a fancy French dish together. Not only is this a fun way to spend your time together, but it also promotes teamwork.

If all goes well, you’ll have a romantic date night meal at home that you prepared with your four hands. And if the food didn’t turn out the way you’d hoped, you are guaranteed to have a laugh and create new memories together.

6. Have a Regular Date Night

Couples experience a greater sense of happiness and less stress when they are spending quality time together.[7] One of the biggest relationship tips for a healthy partnership is to include a date night in your weekly routine.

The National Marriage Project found that having a weekly date night can make your relationship seem more exciting and helps prevent relationship boredom.[8] It also lowers the probability of divorce, improves your sex life, and increases healthy communication.

Some great ideas for what to do on your date night include:

  • Have a movie marathon – Gather up your favorite flicks and cuddle up on the couch.
  • Play games together – Cards, board games, video games, and other creative outlets are a fun way to spend quality time together.
  • Recreate your first date – Go back to that restaurant and order the same meal you did when you first got together. You can spice up your evening by pretending you’re strangers meeting for the first time and see how sexy the night gets.
  • Plan a weekend getaway – There’s nothing better than traveling with the one you love.
  • Dinner and a movie – A classic!
  • Try a new restaurant – Make it your mission to rate and try all of the Mexican restaurants/Irish pubs/Italian trattorias in your area.
  • Have a long sex session – Intimacy promotes the release of the oxytocin hormone which is responsible for a myriad of great feelings.[9]
