1
On a daily basis, you spend between a third and half your waking hours daydreaming.
2
That may sound like a huge waste of time,
3
but scientists think it must have some purpose,
4
or humans wouldn't have evolved to do so much of it.
5
So to figure out what's going on here,
6
let's take a closer look at the mind wanderer in chief, the bored teenager.
7
Wouldn't it be cool to discover something,
8
anything, like even this plant?
9
Just to be one of those explorers who sails around drawing stuff for years on end and everyone thinks they're a genius?
10
But does anyone even do that anymore?
11
Is there anything left to discover?
12
And would I be tough enough to deal with the dysentery or scurvy or piranhas or whatever?
13
I barely have the endurance to make it through track practice.
14
But I will.
15
Any day now, I'll have the discipline to show up before sunrise and practice.
16
I'll win all my races.
17
Winning will become so easy I'll pick up other events just for fun.
18
And once I'm in the Olympics,
19
they'll have no choice but to crown me team captain,
20
which I will graciously accept.
21
And will I be nasty to the teammate who yelled at me?
22
No. I'll just calmly say,
23
hope you're in a better mood.
24
Okay.
25
Yours and other people's daydreams might sound or feel something like that.
26
Let's see what was going on.
27
To see what parts of the brain are active when you're doing a task,
28
or thinking, or daydreaming, scientists use brain imaging techniques that show increased blood flow and energy expenditure in those areas.
29
These brain areas are active,
30
working together, and communicating with each other.
31
Taken together, they're called the executive network.
32
When your mind starts to wander,
33
a different set of brain areas becomes active.
34
These areas make up the default mode network.
35
The name default mode makes it sound like nothing is going on.
36
And in fact, for many years,
37
scientists associated this pattern of activity with rest.
38
But a closer look reveals that these are the brain areas involved when we revisit a memory,
39
when we think about our plans and hopes,
40
and yes, when our minds are wandering off on a wild daydream.
41
The mind can wander to unproductive or distressing places and brood over negative past events,
42
like an argument.
43
You can also wander to neutral everyday matters,
44
like planning out the rest of one's afternoon.
45
But where mind-wandering really gets interesting is when it crosses into the realm of free-moving,
46
associated thought that you aren't consciously directing.
47
This kind of mind-wandering is associated with increases in both ideas and positive emotions,
48
and the evidence suggests that daydreaming can help people envision ways to reach their goals and navigate relationships and social situations.
49
think there may be two essential parts to this process.
50
A generative phase of free-flowing ideas and spontaneous thoughts,
51
courtesy of the default mode network,
52
followed by a process of selecting,
53
developing, and pursuing the best ideas from that generative burst,
54
driven by logical thinking thanks to the executive network.
55
A host of imaging studies suggest that these two networks working in sync is a crucial condition for creative thinking.
56
Taken together, the evidence clearly suggests the logical realm of the executive network
57
and the imaginative realm of the default mode network are closely related.
58
And as you can see,
59
the executive network is still playing a role when the default mode network is doing its thing during daydreaming.
60
In teenagers, the prefrontal cortex and other areas involved in executive function are still developing.
61
But teens are perfectly capable of thinking through their problems and goals,
62
especially when given space to do so on their own.
63
If it seems like friendships formed during adolescence are particularly special,
64
that's That's because even on a scientific level, they are.
65
But can the same be said of first love?

練習のコツ
この動画のスピードと言葉のトーンに合わせて、英語シャドーイングを行うことが効果的です。まずは、動画を見ながら内容を理解しましょう。次に、リズムに合わせて声に出してみることです。特に、shadow speechを意識して、話者のトーンや感情を捉えることが大切です。これにより、英語の発音を良くする練習ができます。
最初はゆっくりとしたペースで繰り返し練習し、次第に早いテンポに挑戦してみてください。特に、日常会話で使われるフレーズを取り入れた部分を選ぶことで、実践的なスキルを身につけることができるでしょう。また、YouTubeで英語学習を通じて様々なアクセントや発音を聞くことが、より自然なコミュニケーションスキルの向上に繋がります。
シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
