The second conditional

if you grew up playing video games like I did, you probably heard lots of conflicting information.

Adverbs of degree

Some say too much gaming will ruin your vision and rot your brain while others claim it improves your hand eye coordination and can even make you smarter.

Transition words & phrases

So what exactly does gaming due to our brain and our body.

To find out I visited, doctors and researchers were seeing brain activity in different frequencies, tested my hand eye coordination against a pro gamer.

You can't catch up and somehow ended up in a sub 200 degree cryo chamber.

All to answer the question, how do video games affect us?

These sports have gone mainstream their college leagues, parents are even getting video game tutors for their kids and thanks in part to smartphones and free games like Fortnite Gamers are playing more than ever before.

So given that we can play virtually anywhere at any time, how is all this gaming changing us physically?

Let's start with the excuse I used to give my mom when I was trying to get a little bit more time on the Atari.

It's making me a better athlete to find out if that's actually true.

I headed to the Sports academy in 1000 oaks California for amateur gamers and esports pros trained under the same roof as traditional athletes.

This is pro gamer Matt Higginbotham, I'm known online as Acadians.

People say, you know, it improves hand eye coordination, it improves response time, What have you seen in your own life if you only play League of Legends, that's like you're only activity with no physical exercise.

In my opinion, you're just going to get out of shape in terms of positive, maybe, maybe cognitive, it would increase the things you're going to use in the game, reacting to things quickly, making decisions quickly.

Let's find out if being an avid gamer actually makes you sharper.

We're going to be taking a bunch of cognitive tests, one after the other.

So we're going to see exactly how our results breakdown.

The Dyna vision board which tests your reaction time.

Your job is to hit the button when it lights up.

Okay, so you're gonna want to rely on your periphery.

I can already tell now matt calm and he's making it look easy.

But this is way, way harder than it looks.

What's called cognitive processing under load.

But unlike the Dyna vision board, there's a voice telling you to do the opposite of what you're actually supposed to do?

Okay, there's gonna be a voice in your head that says stop and go green.

The last test measures your ability to track multiple objects.

We had to keep tabs on certain spheres as they floated around in a three D.

Kind of like trying to win two games of three card monte at the same time.

I got better at it after like eight of them.

Um My confidence is shaken at this point of truth.

It's always these tasks are built to really push your cognitive processing but but at the same time give you measurable results and immediate feedback matt Outperformed you in the more complex tasks.

So as task got more complicated and had a significant amount of distractions and opportunity for the brain to start thinking about something that wasn't primary to the task.

He outperformed you pretty significantly at those tasks if we were to compare both your scores to a normal population of which we have data.

He's in the 98th%ile and you're probably the 60 or 70%ile.

So are we talking about self selection here?

Is is it that people who are good at this stuff are playing games or is there proof that games can actually improve your cognition in that way?

No, I think for sure games can help improve your cognition.

Playing video games can be very high speed, can create a lot of chaos, create a lot of multiple environments where you have to make decisions and all of these reforming skills in the brain.

So no, I I think in general, just like in every capacity of human performance, we all start with some baseline Based on genetics, but the opportunity to train cognition I think is really powerful.

Okay, so a pro-Gamer who's 20 years younger than me beat me in a few cognitive tests.

But what does science have to say about all this video games is a hugely broad category.

Um and we know for sure that the impact of a game has to do with what you're asked to do.

So because of that different games will have different impacts on on the brain.

You know, you wouldn't ask what's the impact of food on your body.

Um you don't want to know the composition of the food, right?

Um and so the same is true of video games.

So um you know, depending on what we would call the mechanics, the dynamics, the content of individual games, that is what would predict how the games will affect your brain?

Action games like counterstrike, Overwatch and Fortnite are some of the most popular with consumers these days.

And Green and his colleagues have two games like those to find out what their impact is.

There are a subtype of games, action games that have been linked with positive effects in perceptual and cognitive skills.

These are games that have lots of fast motion in them.

So items first come at the edges of the screen, the need to make quick and accurate decisions under time pressure.

Based on 15 years worth of studies, researchers have found that action games biggest positive effects were on perception, how our senses interpret external stimuli like sights and sounds, spatial cognition which helps you orient yourself in and navigate three d environments and top down attention.

The ability to focus on one object while ignoring distractions.

How far that generalizes I think is a pretty open question.

So my expectation is that there are plenty of people who show pretty exceptional hand eye coordination with the joystick might not be able to catch a baseball very well.

Um And so um it's certainly the case that um perceptual motor skill development in one area won't necessarily generalize to all areas.

I'm curious about thoughts that you have about the thresholds between benefits gained from action games and where those diminishing returns might kick in.

You will get more learning gain from smaller sessions spread out over time than one big block.

With respect to perceptual and cognitive skills.

We've either seen a positive impact or a null impact.

We haven't seen any area that has been damaged where there is worse performance.

So those are the positive effects of playing action games.
