Teens and Their Developing Brain

 


Do you have an adolescence or teen in your household? What if you have more than one? Oh my! If that is true, I hope you take the time for a little 'R & R' (research & restraint). Your child is about to experience one of the most confusing and frustrating times in their human development - and it may last for years!

LOOKING BACK

I used to joke when my daughters were teens, "If I could just put them in a brown paper bag when they turned 13 and take them back out in about 3 years, they would be beginning to act like human beings again." All joking aside, I was quite wrong in the number of years that teen changes were beginning and ending. Research tells us today that teen development likely begins at the onset of puberty, which in fact could be as early as 10 and even younger in some children. In other words, the age of puberty continues to become earlier and earlier in children as time goes by.

THE BRAIN IS CHANGING TOO

Book 1
In relationship to the onset of puberty, a teen's brain begins to change just as the rest of their body is changing. At the front of the brain is the area called the prefrontal cortex. This area is responsible for things such as decision-making, judgement, and more. What we see in the prefrontal is a constant relationship of experiences from the past building on each other and making sense of it.

There is a second area in the brain called the limbic system.  Think of it as a lookout for the brain searching for things that could be considered an emotional benefit or risk - most important, the limbic is constantly looking for things considered rewarding. The limbic sends a message to the prefrontal cortex which analyzes the message and decides what to do next. But, what if there is no decision of what to do next? (The limbic is not able to do the work of the prefrontal cortex.)

WHAT DOES ALL THAT MEAN?

The prefrontal cortex is developing during the teen years and cannot always take in all the messages coming from the limbic. Think of it as a version of limbic overload, that allows the rest of the brain to react in ways such as impulsiveness, poor reasoning, aggression, and susceptibility to other teens and their behaviors - some of which may not good. These stressful situations can be a fast path to limbic overload.

Book 3
Example: Imagine a teen frustrated by a newly developed relationship that is coming to an end (this is an example from my newest teen book of the Book of Katie series). The character in the book is becoming more stressed by the moment and begins to send message after message to the prefrontal cortex. The character suddenly can't think of what to do (Teens often describe this moment as going blank.). At that point in time, the brain can react in a multitude of ways such as uncontrollable crying, flight, or aggressiveness. Unfortunately, the brain will not likely have the benefit of the prefrontal cortex in choosing a good decision. In this example, a young adult worked to calm down the character in the book, removed the stressors, and began to slowly add new information to the prefrontal cortex.

WHAT SHOULD YOU DO AS A PARENT?

Read everything you can get your hands on and not be afraid of professional advice for better parenting skills.

Last... be patient! Control your own decision-making and remain calm.

THE BOOK OF KATI - VOLUME 3 - SECRETS

SECRETS  Sshh, can you keep a secret? Should you keep a secret? Life in Tiny continues to be full of adventures for the Cow Pie Gang and the Fair November brings the whole town to life. The trials and tribulations of tween life continues with first dates and first break ups. When Kati uncovers a huge secret, she is torn and doesn't know if she should tell or not. After a week of turmoil and soul searching she finds out that some secrets aren't meant to be kept while other secrets reveal delightful surprises. 5.0 out of 5 stars   Wonderful series Reviewed in the United States on January 25, 2018 Love the characters in this series. They are strong, true to life middle schoolers growing up in a small town. The adults in their lives are hands on without being too intrusive. I really like how the author portrays the thought processes the kids go through trying to understand their own issues and those of the people around them.

Teaching Youth to Think

I recently had the opportunity to observe a 10-year-old boy learning to  code  a basic computer program. For those of us computer challenged,  coding  is the programming language that designs software, apps, computer games, and even websites such as mine. Is this a lesson for gifted children? Actually not! Everyone can learn the basics of programming in this day and age - we just need to  learn how to think ! The first step in this boy's learning was to teach him basic vocabulary, facts, and rules. This was his  foundation  to coding. A designed activity followed to engaged the boy in demonstrating that he really understood the foundation.  (Note: There were no time restraints on this child's learning. Why must we rush our kids?) And then... wonderful things began happening! The boy looked at the entire foundation and began  systematically analyzing it . He examined carefully all the parts and how they related to each othe...

TELL US MORE ABOUT YOU

I was at a community author talk not too long ago for aspiring authors, when a young lady in the middle of the room raised her hand, "Would you tell us more about your background? What were the influences or experiences in your life that led to your writing?" I smiled at the request, looked down at my feet for a brief moment, and nodded my head in silence. "So many," I answered, "so very many!" I was born in a small rural community in the Pacific Northwest. Our small one-bedroom home was situated just a stone's throw from the banks of the Snake River. Being an only child, I slept in the basement next to the warm coal furnace. During our freezing winters, this was an ideal place to have bed.  It was at this time, my mother took me to the library for the very first time. I stared at the rows of books in disbelief and excitement. My very first picture book book was one about dinosaurs. This love of books would later include Mark Twain's cha...
