to start it

來開始播放。

and then you can just lean back 片語動詞

然後你只要往後一靠，

and let the autoplay playlist bring the knowledge right to your brain. 文法

讓自動播放清單把知識直接送進你的腦袋。

As you already know, 表達脈絡

正如你已經知道的，

it doesn't really work on mobile phones yet,

它目前在手機上還不太能用，

so wait until you're in a better position to lean back. 慣用語

所以等到更適合往後靠著看的時候再看吧。

In the meantime, 表達脈絡

在此期間，

let's get saccadic. 慣用語

讓我們來點掃視吧。

No, not psychotic,

不，不是精神錯亂，

saccadic,

是掃視，

referring to what is known as a saccade, 講解

指的就是所謂的掃視運動，

the quick movements that our eyeballs make

也就是我們的眼球做出的快速移動，

when we move from one object to the other. 文法

發生在我們把視線從一個物體移向另一個物體時。

As you may remember from a previous Lean Back,

你或許還記得之前某集 Lean Back 裡提到過，

some animals like most birds 用詞

有些動物，例如大多數鳥類，

cannot move their eyeballs.

無法轉動眼球。

And so to look from one thing to another,

所以，要從一樣東西看向另一樣東西，

they have to move their head really, really fast.

牠們就得非常、非常快速地轉動頭部。

And to keep the world from being blurry 文法

而為了不讓眼前的世界變得模糊，

when their bodies move,

當牠們的身體移動時，

they have to keep their heads completely stationary. 文法

牠們必須讓頭部完全保持不動。

But here's the neat thing about saccades. 表達脈絡

但掃視運動有個很有意思的地方。

When our eyes move,

當我們的眼睛移動時，

there's a quick blur between one destination and the other.

從一個目標移到另一個目標的過程中，會出現短暫的模糊。

And that blur is completely incomprehensible to our brain. 片語搭配

而我們的大腦完全無法理解這段模糊。

So what our visual system does 文法

因此，我們的視覺系統會

is erase it from our memory

把它從記憶中抹去，

and instead replace that little fraction of a second 片語搭配

轉而將那一小瞬間

that our eye moved during 文法

——也就是眼睛移動的時間——

with the very next thing we see.

替換成我們緊接著看到的景象。

This leads to a really amazing illusion 片語搭配

這就產生了一種非常神奇的錯覺，

called the stopped clock illusion. 文化背景

稱為「停鐘錯覺」。

You may have noticed this before 文法

你以前可能注意過這種現象，

if you've ever been in a room with a clock 文法

如果你曾待在一個有時鐘的房間裡，

with a second hand, 用詞

而那個鐘還有秒針，

like in a classroom,

例如教室，

darting your eyes back and forth 片語搭配

你一邊快速地來回轉動視線，

waiting for class to be out.

一邊等著下課。

Now here is what happens. 表達脈絡

接著就會發生這種情況。

Right when you dart your eyes to the clock, 文法

就在你猛然把視線轉向時鐘時，

that very first second, 用詞

最開始的那一秒，

that very first movement of the second hand

也就是秒針最開始的那一下移動，

that happens when your eyes reach it,

恰好發生在你的目光落到鐘面上時，

seems longer than every other second afterwards. 文法

看起來會比之後的每一秒都更長。

Look away from the clock 片語動詞

先把視線從時鐘移開，

and then look

然後再看過去，

and that first second will seem to linger

最開始的那一秒就會像是遲遲不肯過去，

as if time itself has stopped. 文法

彷彿時間本身停住了。

The reason for that is that your brain replaces the time 文法

這是因為，你的大腦會把這段時間，

it took for your eye to go from here to the clock

也就是眼睛從這裡轉向時鐘所花的時間，

with an image of the first thing you saw,

替換成你最先看到的東西的畫面，

which was the second hand.

而你最先看到的就是秒針。

And so that little fraction of a second of time

因此，那一小瞬間

is added to the length of time 片語搭配

就會被加到

it takes the second hand to move.

秒針移動所需的時間上。

What's really mind-blowing about this entire effect 講解

這整個效應真正令人震撼的是，

is that it happens all the time. 片語搭配

它無時無刻不在發生。

All day, as you look around the world

一整天裡，當你觀察周遭世界，

from one point to another,

把目光從一個點移向另一個點時，

that little fraction of a second

那一小瞬間

that your eyeball was moving

正是你的眼球移動的時間，

is lost and your brain just replaces it

它會消失，而大腦只是把它

with the very next thing that you see.

替換成你緊接著看到的景象。

Now it might just be a tiny, tiny amount of time, 表達脈絡

這或許只是一丁點時間，

but over the course of an entire day, 片語搭配

但在一整天裡，

those little fractions of a second

這些零碎的瞬間

can add up to almost 40 minutes. 片語動詞

加起來可能接近 40 分鐘。

40 minutes of every day that you're awake

你每天清醒的時間裡，有 40 分鐘

are lost because our eyeballs move.

會因為眼球轉動而消失。

And as always,

一如往常，

thanks for watching.

感謝收看。
