1
With social media sites being used by one third of the entire world,
2
they've clearly had a major influence on society.
3
But what about our bodies?
4
Here are five crazy ways that social media and the internet are affecting your brain right now.
5
Can't log off?
6
Surprisingly, 5-10% of internet users are actually unable to control how much time they spend online.
7
Though it's a psychological addiction as opposed to a substance addiction,
8
brain scans of these people actually show a similar impairment of regions that those with drug dependence have.
9
Specifically, there's a clear degradation of white matter in the regions that control emotional processing,
10
attention, and decision making.
11
Because social media provides immediate rewards with very little effort required,
12
your brain begins to rewire itself,
13
making you desire these stimulations,
14
and you begin to crave more of this neurological excitement after each interaction.
15
Sounds a little like a drug, right?
16
We also see a shift when looking at multitasking.
17
You might think that those who use social media or are constantly switched between work and websites are better at multitasking,
18
but studies have found that when comparing heavy media users to others,
19
they perform much worse during task switching tests.
20
Increased multitasking online reduces your brain's ability to filter out interferences
21
and can even make it harder for your brain to commit information to memory.
22
Like when your phone buzzes in the middle of productive work.
23
Or wait, did it even buzz?
24
Phantom vibration syndrome is a relatively new psychological phenomenon where you think you felt your phone go off,
25
but it didn't.
26
In one study, 89% of test subjects said they experienced this at least once every two weeks.
27
it would seem that our brains now perceive an itch as an actual vibration from our phone.
28
As crazy as it seems,
29
technology has begun to rewire our nervous system,
30
and our brains are being triggered in a way they never have before in history.
31
Social media also triggers a release of dopamine, the feel-good chemical.
32
Using MRI scans, scientists found that the reward centers in people's brains are much more active
33
when they're talking about their own views as opposed to listening to others.
34
Not so surprising, we all love talking about ourselves, right?
35
But it turns out that while 30-40% of face-to-face conversations involve communicating our own experiences,
36
around 80% of social media communication is self-involved.
37
The same part of your brain related to orgasms,
38
motivation, and love are stimulated by your social media use,
39
and even more so when you know you have an audience.
40
Our body is physiologically rewarding us for talking about ourselves online.
41
But it's not also self-involved.
42
In fact, studies on relationships have found
43
that partners tend to like each other more if they meet for the first time online rather than with a face-to-face interaction.
44
Whether it's because people are more anonymous or perhaps more clear about their future goals,
45
there's a statistical increase in successful partnerships that started online.
46
So while the internet has changed our verbal communication with increased physical separation,
47
perhaps the ones that matter the most end up even closer.
48
Speaking of social media, we had you ask us questions on Twitter,
49
Instagram, Facebook, Tumblr, Google+, and every other social platform we could find,
50
and did a Q&A video over on ASAP Thought,
51
so if you feel like getting some insider info on ASAP Science and behind the scenes,
52
check it out with the link in the description.
53
Got a burning question you want answered?
54
Ask it in the comments or on Facebook and Twitter.
55
We also finally got a P.O.
56
Box for all of you amazing science lovers who have requested to send us mail or other stuff over the years.
57
And we'd love to hear from all of you,
58
so feel free to use the address on the screen or in the description box.

Qu'est-ce que la technique du Shadowing ?
Le Shadowing est une technique d'apprentissage des langues fondée sur la science, développée à l'origine pour la formation des interprètes professionnels. Le principe est simple mais puissant : vous écoutez de l'anglais natif et le répétez immédiatement à voix haute — comme une ombre suivant le locuteur avec un décalage de 1 à 2 secondes. Les recherches montrent une amélioration significative de la précision de la prononciation, de l'intonation, du rythme, des liaisons, de la compréhension orale et de la fluidité.
