- Why do teenagers seem so much more impulsive, so much less self-aware than grown-ups? Cognitive neuroscientist Sarah-Jayne Blakemore compares the prefrontal cortex in adolescents to that of adults, to show us how typically "teenage" behavior is caused by the growing and developing brain.

I'm almost 14 years old. I've only dealt with teenagers just like me being demonized for crap we can't physically or mentally control. Its refreshing to finally see someone understand how we feel and take the scientific side and acknowledge it's not really completely our fault we act this way.
happy birthday?
welcome to being 17
I feel like it is easy to hate in the absence of information. This was an extremely educational talk for me and it helps me understand myself and others around me.
+HVallejo B. more likely it means she almost certainly lacks the neurocognitive capacity to figure it out on her own. What Blakemore has done is to provide scaffolding (look up Lev Vygotsky) to enable her to understand.
I feel better after watching this. I wish there were TEDs like this, which take in not only the scientific but also the emotional side of things.
whos here from your ed psych class lol
Me
LA class
ahaaha Me!! 😂
her use of language is breath-takingly precise.
_its okay_
Weird comment
I noticed that too. She was definitely educated proper good and that.
I am so glad that she provided the Shakespeare quotes. Lately, I've been hearing more and more about the teenage/adolescent years being a recent/made up western concept. Though our society does seem to devalue what teenagers are capable of, there is now proof that some very specific developments are happening during that time in life. It's a real stage that requires unique guidance & attention. Excellent talk.
I don't see how it could be considered a made up concept. Our brains don't evolve as fast as culture changes.
+Androeda Lasso It is a product of culture in the sense that adolescents act differently and do very different things than they used to. However, the brain still developed in the same way in the past.
I know you said this six years ago but I'm literally doing an assignment on this speech and I'm like 3 weeks late on it
@@gdshtroyer Hope you finished! If not pick a day and dig in!
I was required to watch this video as part of my training to become a foster parent. It was really interesting and quite entertaining. Thank you!!
It's heightened self awareness. If we understand that kids are going through this period and what is happening to them, we can tap into their self consciousness and help them learn more about what it is that is happening to them and prevent misunderstandings that typically lead them to all the crazy behavior. This is when they want to know and experience more than ever. The heightened activity must be harnessed for good or it will entrench negative behaviors.
2023 and this short video is an excellent resource for all adults. Adults, please offer teens and young adults compassion instead of ridicule, understanding instead of harsh criticism, guidance instead annoyance. Simply put; a farmer doesn't stomp and injure the crop that he's trying to grow and then wonder why the crop isn't growing or responding properly..but adults do just that to young children and teens daily
i'm 50 and i feel like i am a teenager again with just one glimpse of her! what a crush out of the blue!
Thank you so much for this. There's so much out there on childhood brain development but finding stuff on adolescent development is surprisingly much harder. It's always surface level stuff that just raises more questions than it answers
This video explains the nature of a great many CZcams commenters. According to her definition, most people here don't seem to have left adolescence.
Excellent, informative for teachers like myself. Thank you.
In order to establish a healthy and enriching environment for the developing adolescent brain, perhaps the implementation of awareness-based classes or workshops may assist all those whom interact with adolescents. There are several approaches one can put into use with respect to such a natural occurrence of human behavior, however, the gradual development of a human being's social (and individual) connectivity takes time - maturation is a process which requires effort and constant attention. Thus, adolescents will continue to express their typical behavior but it can be in more moderate and tolerant ways. Simply, culture and its many systems (i.e. educational, athletic) may need to emphasize the importance of having adolescents (or even children, if possible) train their malleable brains to build a more intimate relationship with self-awareness, whether through meditation or other mindfulness-based exercises.

Everyone should read Blakemore's Inventing Ourselvesssss! That's very amazing! I am currently in my late adolescence and her book reveals a lot of mysteries about adolescence to me!
she is great brilliant. Opened my eyes.
Really valuable content and so fantastic she is studying this and challenging perceptions of adolescent behavior. It is definitely the most high-speed nervous speaker ted talk I have ever seen though, the type where you feel like you need to take a breath after because they didn't breathe the whole time.
12:19 (for school)
Blakemore's lecture reminds me of Ken Robinson's speech at TED, on the need to restructure our education system around creativity, as much as we emphasis math, science and language. While Dr. Robinson provides the social and economic basis for why this must be done, Dr. Blakemore provides the scientific basis of why the adolescent brain thrives particularly well in an environment which fosters creativity. For those who haven't seen Robinson's popular lecture on TED:

this helps for my essay!!!!! thx
Can someone help me connect her ideas? Like how gray matter declines during adolescence, and how good people are at reading social expressions and interactions and then her behavioral studies. What do you think the main point that she is trying to get at with these?
Teenagers tend to have different mental strategies in social communication or decision just like what she flashed in the screen the picture of a play (sport) that connects what she said or state about the ultimatic social emotional response and also how good we are in reading person's feeling. The 3 person wearing yellow is somewhat different in expressions.
Ms Blakemore's presentation is excellent. She is one of the most articulate and clear speakers. She explained this complex subject in such interesting and dynamic language.
And such beautiful and expressionate eyes.
Notes:
brain development does not stop at childhood, instead it continues to develop right through adolescence and into the 20s and 30
prefrontal cortex - planning, social interaction, self awareness
dramatic growth adolscence

Fascinating. would like to show this to my teenage students but my guess is that they wouldnt be able to concentrate long enough to understand it!
THANK YOU
I think Teenagers are really good at seeking out new experiences, they seeking out risks and they recognizing social or being sensitive to social and emotional information.
Great talk, thank you, although not surprised, it actually makes sense.
POV ur here from your psych class🫵🏿🤭
Looking forward to this one!

Is this why the teaching styles of Stand and Deliver works so well?
Blakemore puts my teaching role of 16-24 year-olds into perspective. Of course, it doesn't hurt that she's brilliant AND lovely.
I always thought that I was the most motivated learner when I was in my teenage, now I know why! Also, 40% of teenagers do not have access to secondary educaiton, that number seems alarming.
Awwwwww - Hugs for my teenage self!
Very Informative! Thank you
When you thought you knew big and complicated words but then you click on this video
5:30 Prefrontal cortex of adolescent brain
11:50 - 14:10 risk taking; removing the stigma of teenage development
Hello ma’am. I’m planning on becoming a psychology major, but tbh it’s very tough. I need your help.
It's also incredibly stressful if you are fighting for tenure, or begging for grant money.
A lot of things are stressful
School of life makes wise
Yes, indeed, education can have a constructive influence on the youngster. But it's not that easy! Brains belong to individuals with their special speed of working and ripening. So differ 'lark-learning-types' from 'owl-learning-types', extraverted learners differ from introverted et cetera. And quite often the long schooling periods prevent the young from getting mature, because schools don't deliver the hard knocks insensitive persons need urgently. Role changing games are not new, and of course they are good training. When that bright girl talks about her grandparents, she seems not to be aware, that reduced schooling is a good thing to learn life. Would have Shakespeare become Shakespeare hanging out in schools and universities?
chuan vai lon em yeu oiiii
❤🙏
In some cultures, they have no knowledge of a teenage rebellious stage, as in, it does not occur.
I would like to know specifically, how to develop the teenage brain. Good information thought.
That would be good and would explain a lot in history she left out like these, www.history.com/news/8-famous-child-prodigies
Develop feo what?? Our brain is a bit dumb??
Excelente! Obrigada por compartilhar estes conhecimentos!
Thank you for this amazing learning video
someone write me a 2 pages essay about this speech of my phy class thx!
2 pages? I could do that standing on my bloody head with my arms tied behind my back and blindfolded! I'm writing a fifty billion word thesis!
Fifty billion word thesis? I could do that while hanging from my bloody neck with my arms lopped off and my eyes burned out! I'm writing a one trillion word textbook!
@@philipwright7054 Oh boy don't get me started.
Since the test is for measuring the ability to understand another's perspective, it is fair
But when she said to only move what the observer could see I automatically discounted and ignored the objects in the grey boxes, isn't that how everyone does it?
On a certain level, we have a drug store in our brain, the neurochemicals that show up in flow: so dopamine, norepinephrine, anandamide, endorphins, and serotonin. If you were to try to cocktail the street drug version of that, right, you're trying to blend like heroin and speed and coke and acid and weed- and point is, you can't do it. It turns out the brain can cocktail all of 'em at once, which is why people will prefer flow to almost any experience on Earth. It's our favorite experience. It's the most addictive experience on Earth. Why? 'Cause it cocktails five or six of the largest pleasure drugs the brain can produce. We're all capable of so much more than we know. That is a commonality across the board. And one of the big reasons is we're all hardwired for flow, and flow is a massive amplification of what's possible for ourselves.
Can I ask anyone explanation, of what we learn from this speech and what we think about the speaker's observations about the adolescent brain?
Can someone summerize this ted talk for me please?
Very informative. Thank you for brain research!
Very interesting! Congratulations!
Amazing. Such a good video
People often talk about the reward circuitry of the brain as a sort of seedy drug dealer that wants to wreck your life, but they fail to take into account the fact that it's the personality that's shaping what the brain reacts favorably to, not the other way around. What adolescents often lack is clear reasons and methods to exert better control over their own thoughts and feelings.
Why do you find his right suspicious?
i have to suspect your right, and those that do still resist are probably not around to talk about it.
Nobody gunna see this but if u did what did u find the most compelling point? Why?
Very nice one.
I also think these experiments are somewhat "not thought out".
What portion of those years are spent hunting and warring and coupling?
Amazing !!
Adolescence is a time of considerable development at the level of behavior, cognition and the brain. What does Dr. Sarah-Jayne Blakemore have to say about the social brain in adolescence?
She is so so so very pretty
This video suits my research essay about the biological development of the adolescent brain and analysis of how the adolescent interpret communication obscurely when an adult speaks with one.
(If anyone has a better thesis for my essay. Feel free to correct and adjust. It will benefit both of us. )):)
Google image searches for "Sarah-Jayne Blakemore" has just spiked...
Scientist often talk about the brain in a biased context. Implying that the teenage mind controls the behavior of the person vs a teenage mind reflecting circumstances that the person is experiencing and adapting to it.

Thinking isn't bad; my problem with it is that it blinds us to major problems in our society.
find it interesting that the identified pre-frontal cortex highlighted @ 6:07 is shaded indigo. how convenient.
those cultures must be profoundly different from our "western" culture.
The oldest quote about rebellious youth I'm aware of comes from Ur in ancient Mesopotamia, 2000BC and has been repeated over and over in ancient Greece, ancient Rome, medieval Europe, etc. etc.
Interesting.
translating from a German translation of the text: "Our youth is degenerate and undisciplined. The young people don't listen to their parents anymore. The end of the world is near"
something along those lines
when did they conducted the research?
Well unless they told me that the other guy had no idea about the occluded objects, I'd simply assume he, being the director, was aware of them and follow the instructions as given.
If the test is ambiguous as to what it wants, even after careful thought, it's no wonder the failure rate stays at 50%. It's just not a fair test, when the "wrong" answer seems right, even in hindsight.
LOL- love it when "hard" science backs up something sociologists and psychologists have known for years.
we'll see
stop watching you tube video's and tidy your room
r u still alive? and no, havent cleaned yet.. never will
@@cyanide2813 not sure if I'm still alive I'll check the habituary in the morning, but seriously clean your room you toe rag !
@@sausage4mash ight keep me updated when u figure out if ur alive or not, either way i still wont clean my room
I see your point. But I know of experiments similar to this where they control for these things (e.g. implying that the director hasn't seen the scene before). Also, there are experiments with different set-ups that actually show that adults are way more capable (results > the %50 here) of taking others' perspectives into account (even when not directly told to do so) than teenagers. Maybe she should have elaborated on the set-up a bit more or used other examples of such experiments.
its very true though
Admittedly im 16 so i'm coming from that perspective but she's right about the way teenagers are viewed in the media. You literally see virtually nothing but mocking and invalidation from adults and yet are told to act like one. Sorry i'm moody and all but you acting like that i shouldn't be upset because i'm "just a hormonal teenager" doesn't help, debra.
You WIN.
name them.
think its best that we assume that if education employs the 'misdirection approach' (that's what i am calling it), then that approach is "incorrect"; in other words, 'results' would improve if this is avoided in teaching, and only used in assessment (if at all).
The odds are that it does occur but is curbed from outside influences like social conditioning about behaviour or other unknown factors.
That's exactly what I thought.
I think this is the only person who can truly understand teens like me...
we need more of her
What was the quote?
What the synopsis of your book Inventing Ourselves . I want to buy this book. Is it for the teenager or for adults/parents?
If you look at other research, especially developmental psychology, it addresses this. According to the data, not every adult develops past the teen stage, so even though they are physically adult they remain mental and emotional teenagers.
that's really interesting, and it actually makes sense when you look at some "adults"
Sarah said 9 studies have shown increased MPFC activity in adolescents, then straight after says studies show decreased activity during the period of adolescence. Can anyone clarify which it is? Does she mean it peaks in adolescence then decreases towards adulthood?
I think she is trying to say that the volume of grey matter peaks in the early adolescence then decreases during adolescence to adulthood.
Ngl this was a assignment for me, im 15 years old
In my lab ...
what about it?
It is what it is. Mature judgement doesn't really start for most people until after the age of 19 to about 21, although it can happen later for some people & earlier for some females.
Guyss, what do you learn from the ted talk of sara jane?

Sheever's mom?
Congratulations. :)
Hi classmates
My comment doesn't suggest that anyone is an idiot, nor that I lack respect. Just that it appears that a lot of comments on CZcams are made without due thought or consideration of consequences. What you say about respect is true, but you need to start by respecting yourself enough to not need to take comments personally and justify yourself.
isn't that the point of anonymous online comments? No one knows me so I can be as obnoxious as I want?
interesting

1:50-1:55 so does this mean that teenagers could function as adult organism better? If they're given say a hypothetical situation, a family, a baby to take care of, a job that is stable and the basic education writing reading math they could in-fact behave better instead of impulsive? So everything the teens are doing their brain is just shaping itself into something immature then? Basically a correlation from peers and the environment which has been said multiple times?
Sounds like to me if Grey matter is needed to mature people and it's synaptic pruning away the unnecessary parts what if it's pruning away the adult parts it's getting because you are in fact delaying true adolescence and adulthood. To me from the sound of it, something that makes someone so mature that goes down the toilet is a disadvantage than an advantage out in the wild. Animals leave their parents to prevent inbreeding then yes test their skills out as our teens are but it's done in a flash. Cows function as adults at 15 and die commonly at 35, humans before modern medicine died at these ages due to disease. So wouldn't the teens who lost their parents need to function as an adult?
Really hard to understand what she's saying.
No- she was saying this occurs from adolescence to "adulthood" but she doesn't say adulthood, because people mature at different speeds and times. Synaptic pruning is used to retrain newer information and collect more relevant information- and also assists in not overcrowding the brain. Grey matter isn't what matures people- it's just cells. Environment plus the development of the frontal lobe (mentioned at the start- it helps decision making and planning) is what makes people "mature."
I would have moved the white truck as a way to convey information. To move the blue truck without saying anything would be deceptive.
