N studie van 8,3 miljoen tieners is pas deur die San Diego State University vrygestel, wat daarop dui dat die jeug van vandag baie langer neem om groot te word. Minder tieners het werk, minder kan bestuur, en minder drink en seks te hê.

"Ek het trendstukke gesien wat hierdie neigings kenmerk, aangesien tieners meer 'deugsaam' was as hulle praat oor dalings in seks of alkohol, of dat tieners 'lui' is as hulle praat oor afname in werk," het Jean Twenge, mede-outeur van die studeerkamer, vertel Seeker. 'Maar ek het gedink dat albei die prentjie misgeloop het - dat tieners langer neem om groot te word.'

Hoewel tieners nie versekeringsbetalings en kredietkaartrekeninge kan uitstel nie, kan hulle dit wel doen stel volwassenheid uit - en aanvanklik het dit gelyk asof tieners hierdie jeugdige tyd eintlik verstandiger as ooit gebruik het. By mense en ander diersoorte hou vertraagde ontwikkeling verband met 'n groter deel van die tyd wat aan leer bestee word. Spandeer vandag se tieners meer tyd as om te werk en te drink oor hul huiswerk?

Ongelukkig ondersteun die gegewens nie 'n nuutgevonde toewyding aan formele onderwys nie - die tyd wat huiswerk en buitemuurse aktiwiteite bestee het afgeneem onder die agtste en tiende klas en bly staan ​​vir hoërskool seniors en Kollege studente. As dit nie huiswerk is nie, wat dan? Studie -outeurs was verbaas. Tieners spandeer seker hul tyd êrens anders.

Twenge bespiegel dat die tyd aanlyn bestee kan word. Sy verduidelik dat rekenaars en slimfone 'sommige van die neigings in die afgelope tien jaar' waarskynlik versnel het, aangesien baie daarvan behels om uit die huis te kom, wat nou minder nodig is om met vriende te kommunikeer. ' Om flipbeker te speel en neem jou afspraak na die flieks, jy moet van jou sitkamerbank afklim. Maar om saam met vriende te kuier, hoef nie meer buite te gaan nie. Tieners kry moontlik nie werk nie, seks nie en neem nie deel aan ander volwasse gedrag nie, bloot omdat hulle dit nie hoef te doen nie.

Twenge en haar kollega Heejung Park het ook ontdek dat volwasse aktiwiteite minder gereeld voorkom tydens tydperke met neigings van kleiner gesinsgroottes, hoër mediaaninkomste en minder siekteverwante sterftes. Die duur van die opleiding het ook die frekwensie van volwasse aktiwiteite verminder.

'N Mens kan redeneer dat minder volwasse aktiwiteite soos drank, dwelms of seks tot 'n gesonder leefstyl kan lei. Alhoewel die skrywers van die studie gekies het om nie die pad te volg nie, hier is 10 maniere waarop vandag se duisendjariges gesonder is as hul ouers.


5 redes waarom tieners optree soos hulle doen

Alle tieners neem dom risiko's waarop hulle eendag terugkyk en wonder wat het hulle gedink. Maar studies het bevind dit is nie omdat tieners nie aan die risiko's dink nie, dit is omdat hulle langer daaroor dink as volwassenes.

Ja, dit is teen-intuïtief. Maar dink so daaraan: as u 'n dieet eet en 'n stukkie lekker sjokoladekoek sien, is dit meer waarskynlik dat u dit sal eet as u net daarna kyk, onthou dat u probeer om gesond te eet en weg te loop, of as sit u daar en dink na oor die voor- en nadele daarvan om dit te eet? Laasgenoemde, duidelik.

Dit is dieselfde met die tienerbrein. Ons brein neem baie langer om volledig te vorm as wat voorheen gedink is. By tieners is die frontale kwab (waar ons besluit neem) nie so verbind met die res van die brein as later in die lewe nie. Dit beteken dat tieners letterlik nie so vinnig as 'n volwassene tot 'n besluit kan kom nie. Tieners neem gemiddeld 170 millisekondes langer om oor die gevolge van 'n besluit te kyk, wat weer die kans groter maak dat hulle besluit dat die risiko die moeite werd is.

2. Toegee aan groepsdruk

Om vriende by die mengsel te voeg, maak dit vir tieners selfs moeiliker om risiko's te vermy.

Volwassenes wonder hoekom hul kinders se vriende hulle so kan beïnvloed. Dit is omdat u brein letterlik daaruit gegroei het sodra u 'n volwassene is.

Een studie met behulp van MRI -skanderings op volwassenes en tieners het getoon dat hul brein baie anders reageer op die teenwoordigheid van vriende wanneer hulle 'n besluit neem. Dit het bevind dat tieners wat nie alleen sou waag nie, of saam met 'n volwassene risiko's sou neem as hulle vriende kyk. Die skanderings het getoon dat die beloningsentrum van die tienerbrein baie meer aktief geword het in die geselskap van hul maats. By studente en volwassenes het die beloningsentrum se aktiwiteite egter op 'n konstante vlak gebly, ongeag wie kyk.

Dit beteken dat tieners, as hulle 'n bietjie ekstra tyd spandeer om te besluit watter keuse hulle moet maak, ook veg teen die oorweldigende interne dryfveer wat ons vertel om goed te doen. Namate die brein op volwassenheid ontwikkel, eindig die verbinding, en ons kry geen ekstra goeie gevoel as ons risiko's neem voor ons vriende nie.

3. Gebrek aan konsentrasie

Hoewel tieners meer soos volwassenes as kinders kan lyk, lyk die brein vir 'n neurowetenskaplike 'n kind. Dit is deel van die rede waarom tieners skielik weer soos kleuters begin optree omstreeks die ouderdom van 14. Terwyl hul liggame verouder, herrangskik hul brein homself op 'n manier wat hom tydelik laat optree op dieselfde manier as toe hy jonger was.

Toe wetenskaplikes kyk hoe tieners se brein funksioneer terwyl hulle tydens 'n opgedraaide taak se aandag afgelei word, vind hulle weer 'n groot hoeveelheid aktiwiteit in die verweerde frontale kwab, veel meer as by 'n volwassene. Tieners het te veel aktiewe grysstof in daardie gebied, iets wat afneem namate ons ouer word. Dit beteken dat hul brein alles wat daar rondom aangaan, probeer inneem en verwerk, en dit letterlik oorlaai. Die meer vaartbelynde brein vir volwassenes werk doeltreffender, wat dit makliker maak om op een ding te konsentreer.

Maar as u in die twintigerjare is en tot op hierdie stadium nogal kranksinnig gevoel het, is dit belangrik om daarop te let dat hierdie chaotiese breinmake -up eers in die vroeë dertigerjare heeltemal tot bedaring kom.

4. Te emosioneel

As dit lyk asof tieners nie omgee vir die gevoelens van ander mense nie, of dit lyk asof hulle niks wil oorskry nie, is dit miskien nie omdat hulle drama -koninginne is nie. Studies het bevind dat tieners dit baie moeiliker vind om stembuiging en gesigsuitdrukkings van ander mense korrek te interpreteer, en daarom reageer hulle soms irrasioneel op emosionele situasies.

Een studie het tieners en volwassenes foto's soos hierdie getoon:

Watter emosie dink jy voel daardie vrou? As u nie 'n tiener is nie, het u waarskynlik vrees beantwoord, net soos elke volwassene in die studie. Terwyl sommige tieners vrees geïdentifiseer het, het 50% van hulle woede of selfs skok gesien. Al die deelnemers was gekoppel aan MRI -masjiene terwyl hulle na hierdie beelde gekyk het, en 'n ontleding van die skanderings het getoon dat volwassenes en tieners twee heeltemal verskillende dele van hul brein gebruik het om te besluit watter emosies die mense voel.

Die tieners gebruik 'n deel van die brein genaamd die amygdala, wat emosies grootliks beheer, terwyl die mees aktiewe deel van die volwasse brein die deel is wat logika en rede beheer. Dit beteken dat as u 'n emosie uitdruk - byvoorbeeld teleurstelling - die brein van 'n tiener 'n kans van 50% het om dit verkeerd te interpreteer as 'n ander emosie, soos woede. Aangesien die emosionele deel van hul brein reeds aktief is deur die (verkeerde) oordeel te neem, is dit meer waarskynlik dat hulle irrasioneel en bo -op reageer.

5. Word dommer

Ouers van tieners wonder dikwels wat gebeur het met die blink kind wat hulle vroeër gehad het. Hoe kan iemand gaan van A tot C kry as dit lyk asof hy dieselfde werk doen? Weereens is die veranderinge in die brein die skuld. Alhoewel die meriete van IK -toetse betwisbaar is, het wetenskaplikes voorheen gedink dat IK gedurende die leeftyd dieselfde bly. Nou blyk dit dat die getal in adolessensie wyd kan wissel.

Al die ekstra grysstof waaroor ons gepraat het, begin doodgaan namate u ouer word. As jy jonk is, bevat die grys goed baie ekstra sinapse wat jou brein help om inligting op te slaan en te verwerk. Maar namate u ouer word, begin u brein stukkies wat nie so gereeld gewoond raak nie, doodmaak. Wetenskaplikes het vroeër gedink daar was slegs een groot "toename" van sinaps "snoei" toe ons kinders was, maar breinskanderings van tieners het getoon dat een net so groot aan die begin van die adolessensie gebeur.

Dit is biologies sinvol, hoekom moet u brein energie mors om dinge te onthou wat nie baie nodig is vir u daaglikse lewe nie? Dit is een van die redes waarom jonger kinders 'n tweede taal baie vinniger kan leer as volwassenes, want hulle het meer sinapse om die inligting te stoor. En as hulle gereeld die tweede taal aanhou praat, sal hulle dit die res van hul lewe onthou.

Maar as daar 'n onderwerp is waarop hulle nie so hard gekonsentreer het nie, soos wiskunde, begin hulle skielik dinge vergeet wat hulle vroeër geweet het omdat die brein die inligting uitvee.
* * *
Op hierdie stadium is ons geskok dat iemand op die ouderdom van twintig is. Of soos Mark Twain gesê het: 'As 'n kind 12 word, moet hy in 'n vat gehou word en deur die gatgat gevoer word totdat hy 16 is. op watter tydstip maak jy die gat oop. "

Ouers van tieners wonder dikwels wat gebeur het met die blink kind wat hulle vroeër gehad het. Hoe kan iemand van A tot C kry, as dit lyk asof hy dieselfde werk doen? Weereens is die veranderinge in die brein die skuld. Alhoewel die meriete van IK -toetse betwisbaar is, het wetenskaplikes voorheen gedink dat IK gedurende die leeftyd dieselfde bly. Nou blyk dit dat die getal in adolessensie wyd kan wissel.

Al die ekstra grysstof waaroor ons gepraat het, begin doodgaan namate u ouer word. As jy jonk is, bevat die grys goed baie ekstra sinapse wat jou brein help om inligting op te slaan en te verwerk. Maar namate u ouer word, begin u brein stukkies wat nie so gereeld gewoond raak nie, doodmaak. Wetenskaplikes het vroeër gedink dat daar slegs een groot "toename" van sinaps "snoei" was toe ons kinders was, maar breinskanderings van tieners het getoon dat een net so groot aan die begin van die adolessensie gebeur.

Dit is biologies sinvol, hoekom moet u brein energie mors om dinge te onthou wat nie baie nodig is vir u daaglikse lewe nie? Dit is een van die redes waarom jonger kinders 'n tweede taal baie vinniger kan leer as volwassenes, want hulle het meer sinapse om die inligting te stoor. En as hulle gereeld die tweede taal aanhou praat, sal hulle dit die res van hul lewe onthou.

Maar as daar 'n onderwerp is waarop hulle nie so hard gekonsentreer het nie, soos wiskunde, begin hulle skielik dinge vergeet wat hulle vroeër geweet het omdat die brein die inligting uitvee.
* * *
Op hierdie stadium is ons geskok dat iemand op die ouderdom van twintig is. Of soos Mark Twain gesê het: 'As 'n kind 12 word, moet hy in 'n vat gehou word en deur die gatgat gevoer word totdat hy 16 is. op watter tydstip maak u die gat oop. "


5 redes waarom tieners optree soos hulle doen

Alle tieners neem dom risiko's waarop hulle eendag terugkyk en wonder wat het hulle gedink. Maar studies het bevind dit is nie omdat tieners nie aan die risiko's dink nie, dit is omdat hulle langer daaroor dink as volwassenes.

Ja, dit is teen-intuïtief. Maar dink so daaraan: as u 'n dieet eet en 'n stukkie lekker sjokoladekoek sien, is dit meer waarskynlik dat u dit sal eet as u net daarna kyk, onthou dat u probeer om gesond te eet en weg te loop, of as sit u daar en dink na oor die voor- en nadele daarvan om dit te eet? Laasgenoemde, duidelik.

Dit is dieselfde met die tienerbrein. Ons brein neem baie langer om volledig te vorm as wat voorheen gedink is. By tieners is die frontale kwab (waar ons besluit neem) nie so verbind met die res van die brein as later in die lewe nie. Dit beteken dat tieners letterlik nie so vinnig soos 'n volwassene tot 'n besluit kan kom nie. Tieners neem gemiddeld 170 millisekondes langer om te kyk na die gevolge van 'n besluit, wat weer die risiko meer die moeite werd maak.

2. Toegee aan groepsdruk

Om vriende by die mengsel te voeg, maak dit vir tieners selfs moeiliker om risiko's te vermy.

Volwassenes wonder hoekom hul kinders se vriende hulle so kan beïnvloed. Dit is omdat u brein letterlik daaruit gegroei het sodra u 'n volwassene is.

Een studie met behulp van MRI -skanderings op volwassenes en tieners het getoon dat hul brein baie anders reageer op die teenwoordigheid van vriende wanneer hulle 'n besluit neem. Dit het bevind dat tieners wat nie alleen sou waag nie, of saam met 'n volwassene risiko's sou neem as hulle vriende kyk. Die skanderings het getoon dat die beloningsentrum van die tienerbrein baie meer aktief geword het in die geselskap van hul maats. By studente en volwassenes het die beloningsentrum se aktiwiteite egter op 'n konstante vlak gebly, ongeag wie kyk.

This means that teens, when spending that tiny bit of extra time deciding what choice to make, are also fighting against the overwhelming internal drive that tells us to do things that feel good. As the brain develops in adulthood, however, that connection ends and we end up getting no extra good feeling from taking risks in front of our friends.

3. Lack of Concentration

While teens may look more like adults than kids, to a neuroscientist their brains resemble a child's. That’s part of the reason teens suddenly start acting like toddlers again around age 14. While their bodies are aging, their brain is rearranging itself in a way that temporarily makes it act the same way it did when they were younger.

When scientists looked at how teenagers’ brains functioned while they were distracted during an assigned task, they found a large amount of activity in that darn frontal lobe again, far more than they would in an adult. Teens have too much active grey matter in that area, something that decreases as we get older. This means their brain is trying to take in and process everything going on around it, literally overloading them. The more streamlined adult brain works more efficiently, making concentrating on one thing much easier.

But if you are in your twenties and have been feeling cocky up until this point, it’s important to note that this chaotic brain makeup doesn’t completely settle down until your early thirties.

4. Overly Emotional

If teens seem to not care about other people’s feelings or seem to flip out over nothing, it might not be because they are drama queens. Studies have found that teens have a much harder time correctly interpreting vocal inflection and facial expressions from other people, and so they sometimes react irrationally to emotional situations.

One study showed teens and adults pictures like this:

What emotion do you think that woman is feeling? If you’re not a teenager you probably answered fear, just like every single adult in the study did. But while some teens identified fear, 50% of them saw anger, or even shock. All of the participants were hooked up to MRI machines while they looked at these images, and an analysis of the scans showed that adults and teens used two completely different parts of their brains to come to a decision on what emotions the people were feeling.

The teens were using a part of the brain called the amygdala, which largely controls emotions, while the most active part of the adult brain was the part controlling logic and reason. That means that if you are expressing an emotion—say, disappointment—a teen’s brain has a 50% chance of misinterpreting it as a different emotion, like anger. Then, since the emotional part of their brain is already active from making that (incorrect) judgment, they become more likely to react irrationally and over the top.

5. Getting Dumber

Parents of teens often wonder what happened to the bright child they used to have. How can someone go from getting A's to getting C's when they seem to be doing the same amount of work? Once again, changes in the brain are to blame. While the merits of IQ tests are debatable, scientists used to think IQ stayed the same over one’s lifetime. Now it turns out that number can fluctuate widely in adolescence.

All the extra grey matter we talked about starts to die off as you get older. When you are young, that grey stuff has lots of extra synapses that help your brain store and process information. But as you age, your brain starts killing off the bits that don’t get used as often. Scientists used to think there was only one major “surge” of synapse “pruning” when we were children, but brain scans of teens have shown that one just as large happens at the beginning of adolescence.

This makes sense biologically why should your brain waste energy remembering things that aren’t very necessary to your day to day life? It’s one of the reasons that younger children can learn a second language much faster than adults they have more synapses to store that information. And if they keep speaking that second language often enough, they will remember it the rest of their lives.

But if there is a subject they didn’t concentrate so hard on, like math, suddenly they start forgetting things they used to know because the brain is deleting that information.
* * *
At this point, we’re shocked anyone makes it to age twenty. Or as Mark Twain said, “When a child turns 12, he should be kept in a barrel and fed through the bung hole, until he reaches 16 . at which time you plug the bung hole.”


5 Reasons Teenagers Act the Way They Do

All teenagers take stupid risks that they one day look back on and wonder what the heck they were thinking. But studies have found it is not because teens aren’t thinking about the risks involved—it’s because they think about them longer than adults.

Yes, that’s counter-intuitive. But think of it like this: If you are on a diet and see a piece of yummy chocolate cake, are you more likely to eat it if you just glance at it, remember you are trying to eat healthy, and walk away, or if you sit there and mull over the pros and cons of eating it? The latter, obviously.

It’s the same with the teen brain. Our brains take a lot longer to fully form than was previously thought. In teens, the frontal lobe (where our decision making happens) is not as connected to the rest of the brain as it is later in life. This means teens literally cannot come to a decision as fast as an adult. Teens take an average of 170 milliseconds longer to go over the consequences of a decision, which in turn makes them more likely to decide the risk is worth it.

2. Giving in to Peer Pressure

Adding friends to the mix makes it even harder for teens to avoid taking risks.

Adults wonder why their kids' friends can influence them so much. That’s because once you are an adult, your brain has quite literally grown out of it.

One study using MRI scans on adults and teens showed that their brains reacted very differently to the presence of friends when making a decision. It found that teens who would not take risks when alone or with an adult were far more likely to take risks when their friends were watching. The scans showed that the reward center of the teen brain became much more active in the company of their peers. In college students and adults, however, the reward center’s activity remained at a constant level no matter who was watching.

This means that teens, when spending that tiny bit of extra time deciding what choice to make, are also fighting against the overwhelming internal drive that tells us to do things that feel good. As the brain develops in adulthood, however, that connection ends and we end up getting no extra good feeling from taking risks in front of our friends.

Adults wonder why their kids' friends can influence them so much. That’s because once you are an adult, your brain has quite literally grown out of it.

One study using MRI scans on adults and teens showed that their brains reacted very differently to the presence of friends when making a decision. It found that teens who would not take risks when alone or with an adult were far more likely to take risks when their friends were watching. The scans showed that the reward center of the teen brain became much more active in the company of their peers. In college students and adults, however, the reward center’s activity remained at a constant level no matter who was watching.

This means that teens, when spending that tiny bit of extra time deciding what choice to make, are also fighting against the overwhelming internal drive that tells us to do things that feel good. As the brain develops in adulthood, however, that connection ends and we end up getting no extra good feeling from taking risks in front of our friends.

3. Lack of Concentration

While teens may look more like adults than kids, to a neuroscientist their brains resemble a child's. That’s part of the reason teens suddenly start acting like toddlers again around age 14. While their bodies are aging, their brain is rearranging itself in a way that temporarily makes it act the same way it did when they were younger.

When scientists looked at how teenagers’ brains functioned while they were distracted during an assigned task, they found a large amount of activity in that darn frontal lobe again, far more than they would in an adult. Teens have too much active grey matter in that area, something that decreases as we get older. This means their brain is trying to take in and process everything going on around it, literally overloading them. The more streamlined adult brain works more efficiently, making concentrating on one thing much easier.

But if you are in your twenties and have been feeling cocky up until this point, it’s important to note that this chaotic brain makeup doesn’t completely settle down until your early thirties.

4. Overly Emotional

If teens seem to not care about other people’s feelings or seem to flip out over nothing, it might not be because they are drama queens. Studies have found that teens have a much harder time correctly interpreting vocal inflection and facial expressions from other people, and so they sometimes react irrationally to emotional situations.

One study showed teens and adults pictures like this:

What emotion do you think that woman is feeling? If you’re not a teenager you probably answered fear, just like every single adult in the study did. But while some teens identified fear, 50% of them saw anger, or even shock. All of the participants were hooked up to MRI machines while they looked at these images, and an analysis of the scans showed that adults and teens used two completely different parts of their brains to come to a decision on what emotions the people were feeling.

The teens were using a part of the brain called the amygdala, which largely controls emotions, while the most active part of the adult brain was the part controlling logic and reason. That means that if you are expressing an emotion—say, disappointment—a teen’s brain has a 50% chance of misinterpreting it as a different emotion, like anger. Then, since the emotional part of their brain is already active from making that (incorrect) judgment, they become more likely to react irrationally and over the top.

5. Getting Dumber

Parents of teens often wonder what happened to the bright child they used to have. How can someone go from getting A's to getting C's when they seem to be doing the same amount of work? Once again, changes in the brain are to blame. While the merits of IQ tests are debatable, scientists used to think IQ stayed the same over one’s lifetime. Now it turns out that number can fluctuate widely in adolescence.

All the extra grey matter we talked about starts to die off as you get older. When you are young, that grey stuff has lots of extra synapses that help your brain store and process information. But as you age, your brain starts killing off the bits that don’t get used as often. Scientists used to think there was only one major “surge” of synapse “pruning” when we were children, but brain scans of teens have shown that one just as large happens at the beginning of adolescence.

This makes sense biologically why should your brain waste energy remembering things that aren’t very necessary to your day to day life? It’s one of the reasons that younger children can learn a second language much faster than adults they have more synapses to store that information. And if they keep speaking that second language often enough, they will remember it the rest of their lives.

But if there is a subject they didn’t concentrate so hard on, like math, suddenly they start forgetting things they used to know because the brain is deleting that information.

At this point, we’re shocked anyone makes it to age twenty. Or as Mark Twain said, “When a child turns 12, he should be kept in a barrel and fed through the bung hole, until he reaches 16 . at which time you plug the bung hole.”
