1
The behavior comes out.
2
And then there's this little narrator up there that turns it into a story that makes us feel coherent and unified.
3
Turns out it's a thing in the left hemisphere that does this and we called it the interpreter.
4
Consciousness is not a linear flow of what's happening around us, but sort of a convenient narrative of what's happening around us, created for our viewing pleasure by the unconscious brain.
5
It's a very powerful force in the human condition, and it's always trying to figure out and seek explanations for our behavior.
6
In my early part of my career, I studied patients who had their two brains disconnected, working out the functions of each hemisphere.
7
Test results show that speech is localized in only one half brain.
8
Doctor Gazzaniga now reconstructs the test.
9
We would put a question to the right non-speaking hemisphere, and it, in effect, would direct the left hand to do something.
10
So the patient would do that. - And Joe sees two words simultaneously.
11
Bell goes to his non-speaking right brain — Music to his speaking left brain.
12
When asked to point to a picture of what he saw, he chooses Bell.
13
And then we would simply say to the patient, well, why did you do that?
14
We found out that in the left brain, there's a special system that seems to always want to explain actions and moods that we have after they occurred.
15
Why do you pick that one?
16
Music. - Music?
17
There was music and bell.
18
And it was a few minutes ago.
19
The last time I heard any music was coming from the bells out here.
20
Banging away.
21
So the bells outside here.
22
What's extraordinary is that Joe's speaking left brain concocts a plausible story of why he pointed to Bell, even when some of the other pictures more obviously represent music.
23
We're learning and appreciating the ways in which we produce our perception, our cognition and our consciousness and all the rest of it.
24
There's evidence that consciousness is not really what it seems to be.
25
We feel our subjective experiences unfolding in the world around us in sort of this linear narrative in which B follows A, in which C follows B and D follows C, but in reality it seems that our conscious narrative might not be that linear.
26
If you think of something like speech, you're probably not aware of my speech in a syllable-by-syllable, word-by-word manner.
27
So, for example, the word mouse could mean a rodent, or it could be the mouse pad of a computer.
28
Well if I say, "The mouse pad was beside the computer," in that case, the mouse can only be understood as a mouse pad.
29
So it seems to be this chunking that happens, in which your unconscious mind reaches a point of analysis by sampling everything that's happening around it to deliver something a nice narrative of the world around us into our conscious mind.
30
I think the human as a storytelling animal, as some people put it, is because the system is continually trying to keep the story coherent, even though these actions may be coming from processors going on outside of, initially, of conscious awareness.
31
It's one of the reasons why people are different too, because people have different experiences, so they have different things they're trying to explain.
32
So your experiences are different than my experiences and so your storyline, and we may start off with the same interpreter, but because all your experiences are different, your actual environmental experience, your temperament differences and all the rest of it, that's going to color everything in a little different way and this interpreter is going to make up a different story about it.
33
Why does the human always seem to like fiction?
34
Could it be that that prepares us for unexpected things that happen in our life?
35
because we've already thought about them in our fantasy world, saw how those characters acted, and so then when we're confronted with it, we're writing it.
36
We've sort of lived through that movie, as it were.
37
So why do we like that stuff?
38
Well, maybe that's a reason why we like it.
39
And to think of all of those things, it seems to me, just to make it all richer, a richer experience.

文脈と背景
このビデオでは、神経科学の観点から人間がフィクションを必要とする理由が探求されています。人間の脳は、出来事を物語として構成し、私たちの理解を助けるための「通訳者」としての役割を果たしています。神経科学者は、左右の脳の機能について多くの研究を行い、特に言語が一方の脳に局在することを発見しました。この知見から、私たちの意識がどのように構成され、物語がどのように形成されるのかを理解する手助けとなります。このような背景を知ることで、英語学習者は自分の経験を物語として理解しやすくなり、より効果的な学びにつながります。
日常コミュニケーションのためのトップ5フレーズ
- 「なぜそれを選んだのですか？」 - Why did you choose that?
- 「これは音楽のように聞こえます。」 - This sounds like music.
- 「あなたの物語はどうですか？」 - What is your story?
- 「それをどう解釈しますか？」 - How do you interpret that?
- 「私たちは異なる経験を持っています。」 - We have different experiences.
ステップバイステップのシャドウイングガイド
このビデオの内容を学ぶために、効果的なシャドウイング（shadow speech）を実践してみましょう。英語スピーキング練習に役立ついくつかのステップをご紹介します。
- 音声を何度も聴く：ビデオを再生し、理解したいフレーズに耳を傾けます。特に重要な部分を繰り返し聴くことで、意味をつかみやすくなります。
- フレーズを書き出す：トップ5フレーズをノートに書き出し、発音に注意を払いながら声に出して言ってみます。これにより、文の構造や発音が身につきます。
- シャドウイングを実践する：ビデオを再生しながら、話し手の後についていきます。最初はゆっくりとしたペースで、徐々に速さを上げていきましょう。
- 録音して確認：自分のシャドウスピーチを録音し、元の音声と比較してみます。この方法で、自分の発音やリズムを客観的に評価できます。
- 意味を理解する：シャドウイングしたフレーズの背景や文脈を理解することが重要です。人間の経験に基づく物語の形成を意識しながら学ぶと、より深い理解につながります。
これらのステップを通じて、YouTubeで英語学習をさらに効果的に進め、shadow speakのスキルを高めましょう。
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。
