  • 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.

      +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 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.

    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.

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

    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.

    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:

      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.

    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?

    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.

    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.

    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.

    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.
