Shadowing Practice: Sounds could relieve back stiffness - Learn English Speaking with Video

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.
36
Thank you.

¿Qué es la Técnica de Shadowing?
Shadowing es una técnica de aprendizaje de idiomas respaldada por la ciencia, desarrollada originalmente para la formación de intérpretes profesionales y popularizada por el políglota Dr. Alexander Arguelles. El método es simple pero poderoso: escuchas audio en inglés nativo y lo repites en voz alta de inmediato, como una sombra que sigue al hablante con solo 1-2 segundos de retraso. A diferencia de la escucha pasiva o los ejercicios de gramática, el shadowing obliga a tu cerebro y músculos de la boca a procesar y reproducir simultáneamente patrones de habla reales. Las investigaciones muestran que mejora significativamente la precisión de la pronunciación, la entonación, el ritmo, el habla conectada, la comprensión auditiva y la fluidez al hablar, convirtiéndola en una de las metodologías más efectivas para la preparación del IELTS Speaking y la comunicación en inglés en el mundo real.
