  • OMG LOL WUT EMOJI EMOJI EMOJI OMG!

  • JUST SAY IT!

  • Message from Trace Dominguez, everyone!

  • Thanks for swiping right on DNews.

  • According to the Pew Research Center on Internet, Science and Tech -- only 35 percent of Americans

  • texted at ALL in 2006.

  • Then in 2015 Pew reported, 100 percent of 18-29 year olds text, duh.

  • But 92% of people over 50 also text!

  • That's a lot of people doing something that didn't even exist a little over ten years

  • ago.

  • It took 80 years -- from 1900 to 1980 -- for cars to get anywhere close to those numbers

  • So, when something like this takes over so quickly, scientists have to struggle to catch

  • up to how it's affecting us!

  • For example, a new study in Epilepsy & Behavior found that when some people text (either on

  • a phone or a tablet) a whole new brainwave appears.

  • In fact, the researchers said they'd never seen anything like this; this brainwave is

  • unique!

  • When a brainwave changes, it's usually because the brain activity is changing.

  • Think of it like the flashing light on your computer.

  • Different patterns can show different things, and this one is new!

  • The researchers aren't exactly sure what this new wave means, but they think it shows the

  • brain is using emotion, attention, motor-skills, and auditory-verbal activity all together.

  • Funnily enough, this only shows up when texting on smaller screens.

  • Indicating, yet again, quote, "people shouldn't text and drive," because texting changes how

  • the brain is functioning.

  • And some of those changes are for the better!

  • For example, in 2009 a study in Bioelectromagnetics found kids who texted had faster response

  • times on computer tests, but were less accurate in their responses.

  • In fact, kids who used mobile phones (in general) had poorer working memory, but had faster

  • learnings for simple and associative memory tasks! and another small study from a 2011

  • British Journal of Psychology argues that kids who use abbreviations while texting tend

  • to use fewer as they get older and more educated, and their spelling scores are better those

  • who didn't text at all.

  • Yet another study says that "skilled texting" also leads to better spelling.

  • There's even a really weird study that shows our brains are forming stronger connections

  • to our thumbs because of texting.

  • According to their results, in Cell, smartphone users who text had more sensitive touch on

  • the end of their thumb than people who didn't -- more phone use, better perception.

  • So strange.

  • But of course, there are also negatives.

  • Multitasking isn't real.

  • Our brains, cannot multitask, we can only serial task.

  • We can pause this main thing, and then do -- [SENDS TEXT] -- then come back to it.

  • But that back and forth takes a LOT more effort than just finishing the first task.

  • You might be arguing with me in the comments already, but that's because you're probably

  • overconfident, sensation-seeking, and impulsive.

  • People.

  • MULTITASKING ISN'T A THING.

  • In fact, Neuroscientist Daniel J. Levitin writes even trying to multitask increases

  • the stress hormone cortisol and releases adrenaline, causing scrambled thinking and mental fog

  • after a while.

  • This happens because your prefrontal cortex has to stop what it's doing, burn some energy

  • to save your spot, and pick up a second task.

  • It can do this quickly, which is why you think you're doing it simultaneously, but you're

  • not.

  • Plus, you have to decide to answer a text, causing decision-fatigue.

  • AND a study in Computers and Human Behavior found people who think they can multitask

  • spend more time studying (to make up for that switching cost) and do poorer in school overall.

  • Texting is changing how our brains work, how we interact with our own bodies, each other,

  • our environment, and how we learn and see the world.

  • It's a massively influential tool.

  • But, like any tool, learning how and when you use it -- is probably more import… [beep]

  • hang on i just have to answer this.

  • [[texting]] What was I saying?

  • Guys, I am not cool.

  • So, can someone tell me what's up with sex texting.

  • Is that what they call it?

  • Sex-exting?

  • Don't worry, Dr. Ali Mattu knows what I mean -- and we wanted to know if sexting can improve

  • your relationship!

  • If you're worried about being bothered by texts, I have a solution!

  • Turn on your airplane mode when you're working or studying.

  • It works!!

  • What do you think?

  • Do you have an out-of-contact strategy?

OMG LOL WUT EMOJI EMOJI EMOJI OMG!
