Luyện nói tiếng Anh bằng Shadowing qua video: Your Phone Is Training Your Brain to Lose Focus | Dr. Andrew Huberman & Joe Rogan

When the phone is in the room, on the table, or under the chair, it doesn't make a difference, the amount of cognitive resources that you need in order to maintain focus is much higher,

and it robs it from your creative and problem -solving ability.

And then, you know, you have the addiction aspect of it, which is very significant, where there's a lot of people that are wasting most of their day just scrolling, doom -scrolling online.

Pure consumption.

You can opt out of that.

And I do, for the most part.

A lot of people do.

A lot of people have gone to flip phones.

There's a bunch of apps that you can get.

And some people have one of those apps that gives you like an hour a day on Instagram that locks you out.

I have social media.

I have X and Instagram on a separate phone.

And it just segregates things nicely.

If people send me stuff, I send it to that phone and then I look at it.

I have a lockbox, like a Supermax prison lockbox for my phone.

That's how I wrote that book.

It was gnarly.

I'm good at putting ass to chair, as they say, and just working.

But when that phone is calling you subconsciously, there's data that are pretty crazy.

They did a study where they have people have their phone upside down on the table

or under their chair in a backpack or in a separate room.

In all three cases, people can focus to the same degree.

But when the phone is in the room on the table or under the chair, it doesn't make a difference.

The amount of cognitive resources that you need in order to maintain focus is much higher

and it robs it from your creative and problem solving ability.

So you can still focus, but you're depleting some other brain resource.

Makes good sense.

Totally makes sense.

Yeah, totally makes sense.

The other one is people, what we call entrain in biology, E -N -T -R -A -I -N, entrain themselves to a particular frequency of distraction.

When you look at your phone on average every 90 seconds or every three minutes or so, and then your phone is not there, let's say you're just working,

every three minutes or 90 seconds or so, people get distracted.

So they're looking for the phone even though it's not there.

So your brain, your focus mechanisms learn to lock on to a particular time scale.

And we had a world -class track coach on the podcast and a few others who was interested in what they do.

And I was saying, do you get different attention spans in different athletes?

And they're like, yeah, like the sprinters can basically focus for as long as a sprint and the walk back.

And then they reset.

And they're like, the marathoners are like these incredible, like they have this like intense focus that can just go and go and go.

I thought it was really interesting.

We entrain ourselves to these rhythms, not just circadian rhythms, but distraction.

I thought, that's pretty cool.

And so then I looked at it differently and I thought, okay, every time I feel the pain of trying to write this paragraph and I'm like, and it's like, it's not happening.

Like, great.

That's the friction.

That's the plasticity.

I think people are sort of geared toward over -optimization.

People need to like chill.

Like you don't have to do everything all the time.

But the point is that your brain learns these skills.

And so I suppose if I have any real fear with AI, it's that people will just become increasingly lazy about using their mind to think.

I just believe in friction, just as you point out.

Do hard things, that's also mentally hard things.

I think it's good.

I think hard, you know, learning to grind through a bit more of that friction point, I think, is a big part of being a healthy human.

And the data tell us it's also what leads to brain longevity.

You get people like Jared Diamond, who was on the podcast the other day, Who's 90?

He's sharp as a tack.

Because he's constantly engaging his mind and he's learning new languages.

He's learning Italian right now as we speak at 90.

That's awesome.

I have such respect for people like that.

I have such admiration for people that maintain their mental and or physical vigor into their 60s, 70s, 80s.

Also he maintains his curiosity and you can tell in the conversation.

Like he's a deeply curious person still.

He still has questions.

He still has a desire for information.

And the optimism seems to be there.

Yeah.

Phương Pháp Shadowing Là Gì?

Shadowing là kỹ thuật học ngôn ngữ có cơ sở khoa học, ban đầu được phát triển cho chương trình đào tạo phiên dịch viên chuyên nghiệp và được phổ biến rộng rãi bởi nhà đa ngôn ngữ học Dr. Alexander Arguelles. Nguyên lý cốt lõi đơn giản nhưng cực kỳ hiệu quả: bạn nghe tiếng Anh của người bản xứ và lặp lại to ngay lập tức — như một "cái bóng" (shadow) đuổi theo người nói với độ trễ chỉ 1–2 giây. Khác với luyện ngữ pháp hay học từ vựng bị động, Shadowing buộc não bộ và cơ miệng phải đồng thời xử lý và tái tạo ngôn ngữ thực tế. Các nghiên cứu khoa học xác nhận phương pháp này cải thiện đáng kể phát âm, ngữ điệu, nhịp điệu, nối âm, kỹ năng nghe và độ lưu loát khi nói — đặc biệt hiệu quả cho người luyện IELTS Speaking và muốn giao tiếp tiếng Anh tự nhiên như người bản ngữ.
