1
Our bodily feelings have important functions.
2
They propel us to take action.
3
For example, when we feel cold, we seek warmth.
4
We assume that these bodily feelings are an accurate indicator of what's actually happening in our body.
5
But this might not be the case.
6
For example, if we show you a red light and then touch your skin with a freezing cold probe, you perceive the probe as being painfully hot.
7
You get it wrong.
8
So what we feel doesn't always reflect what is actually happening.
9
My research evaluated a feeling that most people have experienced, the feeling of stiffness in a joint.
10
And we wondered, is a joint that feels stiff actually biomechanically stiff?
11
Or, could feelings of stiffness serve another purpose, such as protecting us from further movement and injury?
12
So to test this, we recruited people who had back pain and feelings of back stiffness, and we used a specialized machine that applies pressure to their back to measure how stiff their back actually was.
13
And what we found was intriguing.
14
How stiff their back felt did not relate at all to how stiff their backs actually were.
15
But it did relate to how protective they were of their backs.
16
We had participants estimate how much pressure they thought that they received, and people whose backs felt stiffer were more protective.
17
They thought that they were getting much more force than they truly were.
18
So if feelings of stiffness reflect protection rather than actual back stiffness, then adding extra information that would increase or decrease the need to protect their back should then alter perception.
19
And given that sound is often paired with feelings of stiffness, think of a creaking, grinding, cracking when you hear, you hear when a stiff joint moves, we decided to pair the sound of a very creaky door to the pressure applied to participants' backs.
20
We discovered that this sound changed perception.
21
People became more protective.
22
They thought they were getting much more pressure than they truly were.
23
And this is a marker of increased feelings of stiffness.
24
And the type of sound mattered.
25
When we used a nicer sound, a gentle whoosh, people had the opposite response.
26
They began to underestimate pressure, which is a marker of decreased feelings of stiffness.
27
But most importantly, we found that the meaning behind sound matters.
28
We tested what happens when the creaky door sound gets less and less creaky over time, kind of like oiling a creaky gate.
29
We found that people began to underestimate pressure.
30
So despite an identical sound, merely changing its volume and thus its meaning, evoked opposite responses.
31
Together, this suggests that feelings of back stiffness don't only relate to what's going on in the joints and the muscles of the back.
32
Rather, they are a protective perceptual construct.
33
And information from numerous sources, including sound, is used to create this perceptual feeling of stiffness.
34
And this has important implications for treatment because it suggests that we may be able to target feelings of stiffness without targeting the stiff joint itself, but instead by targeting how the perception is created.
35
So in the future, when you have a stiff back or a stiff knee, the treatment you get might include listening to different sounds while you move so that we can break the association between feelings of stiffness and movement.

Thank you.

練習のヒント
このビデオのスピードやトーンに合わせて、shadow speechを活用することが重要です。特に、感覚や感情に関連する表現を強調し、リズムに合わせて発音する練習をしましょう。英語の発音を良くするには、模倣が効果的ですので、話し手のトーンを注意深く聴きながら、shadow speakを行ってみてください。
また、内容が深いビデオの場合は、部分的に一時停止してから繰り返し発声することもおすすめです。これは、特に感情的な要素が含まれるフレーズの練習に役立ちます。IELTS スピーキング対策としても、こうした練習がフィードバックを重視し、聞き取りやすい発音を身に付ける助けとなります。
音の効果や意味に注目し、様々な視点から理解を深めることが習得につながりますので、ぜひ繰り返し模倣し、あなた自身の言語感覚を豊かにしていきましょう。
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。
