1
Humans know the surprising prick of a needle, the searing pain of a stubbed toe and the throbbing of a toothache.
2
We can identify many types of pain and have multiple ways of treating it.
3
But what about other species?
4
How do the animals all around us experience pain?
5
It’s important that we find out.
6
We keep animals as pets, they enrich our environment, we farm many species for food, and we use them in experiments to advance science and human health.
7
Animals are clearly important to us, so it’s equally important that we avoid causing them unnecessary pain.
8
For animals that are similar to us, like mammals, it's often obvious when they're hurting.
9
But there's a lot that isn't obvious, like whether pain relievers that work on us also help them.
10
And the more different an animal is from us, the harder it is to understand their experience.
11
How do you tell whether a shrimp is in pain?
12
A snake? A snail?
13
In vertebrates— including humans— pain can be split into two distinct processes.
14
In the first, nerves in the skin sense something harmful and communicate that information to the spinal cord.
15
There, motor neurons activate movements that make us rapidly jerk away from the threat.
16
This is the physical recognition of harm called nociception.
17
And nearly all animals, even those with very simple nervous systems, experience it.
18
Without this ability, animals would be unable to avoid harm and their survival would be threatened.
19
The second part is the conscious recognition of harm.
20
In humans, this occurs when the sensory neurons in our skin make a second round of connections via the spinal cord to the brain.
21
There, millions of neurons in multiple regions create the sensations of pain.
22
For us, this is a very complex experience associated with emotions like fear, panic and stress, which we can communicate to others.
23
But it’s harder to know exactly how animals experience this part the process, because most of them can’t show us what they feel.
24
However, we get clues from observing how animals behave.
25
Wild, hurt animals are known to nurse their wounds, make noises to show their distress, and become reclusive.
26
in the lab, scientists have discovered that animals like chickens and rats will self-administer pain-reducing drugs if they’re hurting.
27
Animals also avoid situations where they’ve been hurt before, which suggests awareness of threats.
28
We’ve reached the point that research has made us so sure that vertebrates recognize pain that it’s illegal in many countries to needlessly harm these animals.
29
But what about other types of animals, like invertebrates?
30
These animals aren't legally protected, partly because their behaviors are harder to read.
31
We can make good guesses about some of them, like oysters, worms and jellyfish.
32
These are examples of animals that either lack a brain or have a very simple one.
33
So an oyster may recoil when squirted with lemon juice, for instance, because of nociception.
34
But with such a simple nervous system, it’s unlikely to experience the conscious part of pain.
35
Other invertebrate animals are more complicated, though.
36
Like the octopus, which has a sophisticated brain and is thought to be one of the most intelligent invertebrate animals.
37
Yet in many countries, people continue the practice of eating live octopus.
38
We also boil live crayfish, shrimp, and crabs, even though we don't really know how they're affected either.
39
This poses an ethical problem, because we may be causing these animals unnecessary suffering.
40
Scientific experimentation, though controversial, gives us some clues.
41
Tests on hermit crabs show that they’ll leave an undesirable shell if they’re zapped with electricity.
42
But stay if it’s a good shell.
43
And octopi that might originally curl up an injured arm to protect it, will risk using it to catch prey.
44
That suggests that these animals make value judgments around sensory input, instead of just reacting reflexively to harm.
45
Meanwhile, crabs have been known to repeatedly rub a spot on their bodies where they’ve received an electric shock.
46
And even sea slugs flinch when they know they’re about to receive a noxious stimulus.
47
That means they have some memory of physical sensations.
48
We still have a lot to learn about animal pain.
49
As our knowledge grows, it may one day allow us to live in a world where we don’t cause pain needlessly.

이 레슨에 대해

이번 레슨에서는 "How do animals experience pain?"이라는 제목의 동영상을 통해 동물들이 느끼는 고통에 대한 과학적 이해를 넓힐 수 있습니다. 학습자는 동물의 고통 감각을 이해하는 데 필요한 다양한 어휘 주제와 문법 패턴을 익힐 수 있으며, 말하기 맥락에서도 활용할 수 있습니다. 특히, 고통을 경험하는 다양한 동물의 사례를 통해 영어 말하기 연습과 영어 유창성을 향상시키는 기회를 제공합니다.

주요 어휘 및 표현

  • Nociception: 해로운 자극을 감지하는 신경의 반응.
  • Conscious recognition: 감각을 인식하고 해석하는 의식적인 과정.
  • Invertebrates: 척추가 없는 동물, 예를 들어, 조개, 해파리 등.
  • Reflexively: 반사적으로, 즉각적으로 반응하는 방식.
  • Value judgments: 감각적 정보에 대한 평가를 기반으로 한 판단.
  • Ethical problem: 도덕적이나 윤리적인 문제.

이 동영상 연습 팁

이 동영상의 내용을 바탕으로 쉐도잉 기법을 활용할 때, 먼저 말하기 속도에 주의하세요. 강연자가 말하는 속도는 자연스럽지만, 학습자에게는 다소 빠를 수 있으므로, 먼저 느린 속도로 따라 해보는 것이 좋습니다. 억양 또한 중요한데, 강조되는 부분을 따라 하면서 각 단어의 중요성을 파악하는 것이 도움이 됩니다. 동물의 감정과 고통을 주제로 한 내용을 다루고 있기 때문에, 관련된 어휘와 표현을 익히는 것이 중요합니다. 이렇게 하면 동물의 고통에 대한 이해도를 높이며, 발음 연습도 자연스럽게 이루어질 수 있습니다. IELTS 스피킹 시험과 같은 실제 상황에서 활용할 수 있는 유익한 연습이 될 것입니다.

쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법

쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
