The Distracted Teenage Brain


Teens often opt for doing something they once found rewarding, even if it no longer is. One implication: They may opt for texting or social networking, even when they know should be focused on other things.

It's so interesting how scientists are linking teenage choices with rewards. I wonder what started to cause this change in the prefrontal cortex. I feel like this article could have added more details about what goes on in a teenager's brain-after all, it is called 'The distracted teenage brain'-instead of just talking a lot about the tests. I'd like to learn more about this, though, because in a couple years this'll be me!

I thought that it was an extremely interesting study that Rogers' team performed, and that it was an amazing discovery that teenage brains were reactant only to things that would benefit them short term, instead of the long run. This category includes things like social media and texting, which offer quick relief from stress and boredom via interaction with others. This explains why teenagers have no real care for the world outside of their own personal area, and why they have no interest in giving long term benefits to themselves. They will often only be thinking about instant gratification. (As opposed to waiting for good things to come) Another thing that Rogers and his team discovered was that teenagers would often try to pursue goals that only previously benefitted them, but are ineffective as of now. Take the test they performed, for example. While the group of 20-35 year olds swiftly moved on from the red and green shapes, the group of the younger teens often dawdled, repeatedly looking at and scrolling over the old shapes. This testing has proved that teens are much slower to forget things that have helped them in the past. While pondering this odd occurrence, I thought about what may have been the evolutionary advantage of this change in teenager minds, that would have been useful in the time of Cro-Magnons and other hominids. Let's say that a prehistoric teenager was going out into the woods. This teen is like most modern day ones, being distracted by things that previously helped them. Say this person spots a deer in the middle of the woods, and though not hungry, the teen's automatic response is to kill the deer, as it benefitted him in the past when he WAS hungry. Another example of this is farming, because since this specific person had been supposedly without food last winter. A developmental quirk like this must have been extremely useful in earlier times, because it provided food for the individual and for the group he was collaborating with. All in all, this was an extremely helpful addition to the human transformation to an adolescent form, and it must have been quite useful to hunters and farmers alike in previous years.

In response to Mina's comment about the article, I have to say that I disagree most completely with you. The purpose of the article was to inform the public about what was happening in the teenagers brain. You'll note that the writing stated what triggered this, and it's outcome. I came up with my own unprovable hypothesis from the data that I read, one that was quite solid if I do say so myself. I think that it proved the point that the article was trying to state quite well, although that is just my opinion. I'm only saying this because you might have missed out on something, and that is why you didn't love the article. :D

P.S. I am in Canada while posting this! :)

I believe that the article was very informative. I think that the experiment that they performed on the teenagers was very creative. I think that if one circle is worth (10 c) and another circle is worth (2 c). Most of the ideas about teenagers being linked to rewards is completely true. I also enjoyed reading this article because I think that the part where it stated that the teenagers realized the value of the different colors, even though they didn't. I think that this was a very valuable article and I'm probably going to show this to my mom! Awesome article!

Justin Y said...

I think it was cool how scientists use the teenage choices with their rewards because of a little change in the prefrontal cortex. I think this article was cool but I didn't get why people "younger" and "older" didn't have this. Otherwise I think this was a very awesome article that helped me learn a lot about this topic.

Lily S. said...

I think that the study these scientists conducted was a very good idea. I think that it was a very interesting idea. It was a great discovery. Teenagers are often portrayed in movies or books as people who only care about themselves and their social life. I think that this is true. It is also stereotypical. I think that teenagers only care about things that they want now, more than what they will want later down the road. Near the end of the article, I thought that it was very interesting how most 20-35 year olds quickly moved from screen to screen no matter what was on it, but teenagers moved slow when there were red or green circles. I agree with Conor. This could have been useful to prehistoric humans. A teenagers natural instinct would be to kill an animal or to grab food. Sometimes they would barely have enough to eat, but if they had the food that the teenager had caught earlier, they could have a good meal. That would be rewarding for them any day. I think that this article was very informative. I learned more about the teenage brain and what goes on inside of it.

Lennox said...

I think that it is so interesting that allures have a bigger affect on teens than on adults. It is also cool that teens keep doing the actions way after the reward is done. I think that rewarding teens can decrease the percent of car crashes caused by teens. It is interesting that teen brains are distracted because adult brains are also distracted with jobs and the work they have to do.

Jenna said...

I thought that this article was very interesting because of it's key points/evidence. I have always wondered why teens don't pay attention when they are driving or doing homework. I have experience with teens and this article is absolute true. I thought that the fact none of the people could answer the question about point values amusing. I can relate that to when a person plays a video game and doesn't pay attention to their surroundings. To conclude I thought that this article was very interesting and informative. I will try to stay focused now more then ever.

Grace said...

In the first trial, when the circle has value, it is key to finding it. People like me, (OK I admit it) try to get things done sometimes for the reward. But, when there were no values to the circles, they still thought:

"Oh, I want the money."

They then realize that there is no value and get to the point of finding the diamond. Like the study said, it didn't happen with adults as much. I think that it is a great study and a great point to make. This might be me someday :P

Olivia said...

I find this article to be extremely astonishing. I am very impressed that scientists have found a true solution to why teenagers are distracted. I personally have done things that were once rewarded. This experiment was truly brilliant and in a way proves that teens can be more focused than adults when there is motivations. I loved this article because it took a problem in the world and truly dissected it. This article was interesting and used detail without being extensive and wordy.

Paisley said...

I think that this was a really interesting study for Rogers' team to perform. I also thought it was amazing that the subconsciousness of the adults and teens understood the concept of the red and green circles, but in consciousness, they had no idea about the pattern. I also thought it was interesting that they were able to single out the blue diamond over time. I think this is a really interesting way to see if teens are distracted, instead of blaming it on immaturity.

James G. said...

I think it is interesting that teens make choices based on rewards. I do think this article could have explained more on how this relationship works, but the article is still informative. I wish that this article talked more about the brain, and not the tests.

Celene A. said...

It's interesting to find out what's actually happening in the teenager's brain. Also, I'll have to agree with Conor.

Julianna said...

WOW! Teenagers! I have to say I knew some teenagers weren't that bright. Also that they don't pay attention and get into trouble, but this proves it. Those kids don't make such smart choices. Teenagers get easily distracted and ignore most important facts. It is not so fair to good teenagers because if a good teen goes to a store, looks around and touches stuff, sometimes the owner of the store kicks them out. What I am trying to say here is that people don't trust teenagers because of their actions, which is not fair. Although I would agree most teenagers make bad actions, but people should give them a chance.
I did some research on why teenagers are rebels and this is the link I found.

http://www.webmd.com/children/features/teenagers-why-do-they-rebel

It talks about the human brains developing and why teenagers are rebels.

Emerson said...

I agree with you, Conor. This sounds like a good theory. However, it is, as you said, untestable and unprovable. I think that it is interesting that the adults moved on from the red circles more quickly, even though younger brains are more plastic and generally better at building new connections.

Owen said...

I think that this is an interesting article about the teenage brain. I was surprised to see that the teenagers in the second test still looked for the circles when they were told to find the diamond. I think that is strange that the teenage brain is not able to control itself as well as an adult brain can. This shows that teenagers do not have as much control over their brain as they might think they do.

Xavier said...

Roger and his team were very smart to do this experiment, because in many fictional books and movies, the make the teenager's brain the dullest. I thought that the article was not articulative enough because it never mentioned if children are more distracted then teens, and this confuses me. I think that the game would be almost impossible to win. I would not guess if I was told if I picked the right color I would get money. Overall this article was useful and interesting. I would like to see an article on how adults focus.

I would not guess if I was told if I picked the right color in the right shape I would get money, I would actually try. Overall this article was useful and interesting. I would like to see an article on how adults manage their stress.

Allie said...

This is a really cool article. The study that this team did was really quite clever. I was wondering at what age the brain was fully developed, and I researched this and found out that the brain isn't fully developed until you are around age 20. After I read this, it arose a question. Did some of the adults from ages 20-25 have the same problems as the teenagers did? Because if they did, then maybe rewards will make them more excited as well. The article didn't answer my question about this, so I will probably do some more researching about it. Also, I think that a teenager's brain is distracted because they have so much going on. I'm not sure if they are purely motivated by "rewards". Teenager's brains are very interesting and I think that now that I know about this, I will try to stay away from doing the same when I become a teen.

Allie said...

I made a mistake in my comment, the brain isn't fully developed until around 25, not 20. Sorry for the mistake!

Derek said...

I think that it is really cool how scientists can relate teenagers choice with being rewarded with something. I think that if you are doing something that you should not be distracted for, the parents should be able to turn of their child's wifi or games whenever they want.

Derek said...

I agree with Conor. I think that the idea works out really well.

Justin Y said...

I agree with Conor about everything except the fact that it never says how it works in detail through actually reactions and it really doesn't explain why it only works with teenagers no someone like you or me.

Justin G. said...

I think that this article was very interesting. I could not believe that teenagers make choices based on rewards. I think one of the main reasons that this happens is because the brain is not fully developed yet and like they said in the article, the teenagers are still immature. I also found it amazing that Roper and his team were able to find out that teenagers are only up for something if it affects them right away and are not interested in thinking for future benefits. Overall, I think this article was very well written and interesting.

Justin G. said...

I also agree with Conor B. on the fact that teenagers have no real effort in something outside of their personal bubble. As well, I agree with Mina that the article could have added a little more detail on the actual topic at hand. I think they at points strayed a little bit from the topic. I also agree with James G. that the article could have explained the relationship more between the prefrontal cortex and rewards.

Jaime said...

I think that it was all of the article was super cool. I mean now I know that when I am a teenager I better be careful so I don't get distracted or procrastinate while doing my homework. It was interesting that adults got a lot quicker and teenagers took a pretty long time just to pick which shape, and which color they wanted. I wonder what is going on in a teenagers mind, that it takes them so long just to answer a simple question of, pick a shape and a color? Overall it was really astonishing and amazing to learn all of these new facts, I never even knew the teenage brain was any different then adults.


P.S. I actually got distracted while reading this.

Kendall said...

I think that I agree with Jamie on this one. When I was reading it I ate dinner, had a tennis lesson, and then finished the article. I think that it is really interesting why teenagers are kind unable to adapt to change. From what is happening, it seems that teenagers have a longer adapting time. What is funny is that they don't mention kids. I wonder if kids have a longer or shorter adapting time that teenagers. We know that adults have a faster reaction time that teenagers, but what about kids? I also found it interesting that while i was tying this, people kept distracting me. I wonder if people are distracted by technology. Because there are studies that staring at a screen for long periods of time makes it harder focus. I wonder if the older generational has a faster reaction time because they have less screen time that the modern teenagers.

Gemma said...

This is again a very interesting article. I always knew that teens and children had a part of their brain that wasn't fully developed, that part was the decision making part, or the distraction part. I never knew that something this would happen though. It is very interesting how when given a new goal in the testing, the teens still sort of focused on the old goal.

Maxwell said...


i think the reason the teenage brain is the most distracted is because they have to text, also I think because their brain is changing to become a adult. It would obviously help if they stopped texting as much as they do today because a adult only texts when they have to but a teenager just texts to just comment about subjects.

Sophia said...

I think this article is very interesting. I also agree with Jaime and Kendall on this. I am soon going to be a teenager and I am already starting to get distracted while doing homework.U also think it is very interesting that they can't really adapt to change. I really like this article

Ben said...

I think that this article was interesting. I knew that teenagers' brains were not as fully developed as adults' brains were, but I didn't think about the fact that teenagers were distracted and lured by the thought of a reward. I think that the test Ropers' team conducted was very cool. It is fascinating how they can determine a motive centered around the thought of rewards based on this game with the circle. I think that the reason why the 13-16 year olds lingered around the old shapes was because they were thinking about the reward, and wanted to make sure they didn't miss a line in the previous shapes.

Oliver said...

I think it is very cool how they gave rewards for finding the green and red circles, but then when there was no reward for finding the circles, the teens were still distracted by the red and green circles, when the adults gradually got faster times.

Brandon D. said...

I think it is really cool how teens are so much more distracted than adults when it comes to money rewards. Even when there were no money rewards, the teens were hesitant to press the diamond.

Mason said...

This is not that interesting to me, I find that most of this is not novel. In addition, I didn't understand the experiment. How did diamonds affect the experiment?

Max S. said...

Truthfully, I didn't think that teenagers were so immature that they had to have rewards. (No offense, teens.) I mean, I get it for a small child as motivation, like saying to a seven year old, "If you do your homework right now I'll give you a chocolate chip cookie," but I don't understand how teenagers need the motivation of texting or going onto their phones. But I do think that it was an amazing discovery, even if I find it unbelievable.

Talia said...

I think it is really cool to see how different the teenage brain is. I wonder if there is a way to alter that part of the brain but I don't think so. I think there should of been more information on the teenage brain and on how it compares to adult brains and children brains. I think the article is sort of proving a stereotype is true. The stereotype that I am talking about is how teenagers like social media and are selfish and text too much. I think this article shows how teenagers do things mostly for rewards and are selfish because of that.

Talia said...

I think the article that Julianna found is very interesting. Like I said, I think there should be more information like the one on the website Julianna found on this article. That website shows more about the teenage brain and how teenagers act. It shows the teenage brain compared to other peoples brains and it doesn't just talk about an experiment that they did.
Here is the website:

Ayden said...

I think that this was a very interesting article on the teenage brain. I was surprised by the results from the test they did on teenagers versus adults. I find it strange that something that used to be associated with a reward but is not anymore would still catch someone's attention. You should stay focused on your main target. The diamond test was really easy too. What I find amazing is not that they are distracted by the once rewarded object, but it is that they are distracted every single time and there is no improvement. I think it is great advice for you to not get distracted by texts, or anything else that could potentially distracted you. Taking short breaks is fine, but answering texts and checking social media websites when you should be doing HW is not a good idea at all. In all, I think this was a great article.

Richie said...

I completely agree with this article. I know for a fact that it has been a growing problem in the USA that teens are texting while driving and etc. It was really interesting that the reward caught their attention. This just proves how important it is to stay focused on the task at hand. Here is an interesting link that I found about why multi-tasking is not as helpful: http://www.health.com/health/gallery/0,,20707868,00.html
