Humans know the surprising prick of a needle, the searing pain of a stubbed toe and the throbbing of a toothache.
0:06.95 – 0:14.08 (7.1s)
2
We can identify many types of pain and have multiple ways of treating it.
0:14.62 – 0:18.50 (3.9s)
3
But what about other species?
0:19.25 – 0:21.50 (2.3s)
4
How do the animals all around us experience pain?
0:21.50 – 0:24.95 (3.5s)
5
It’s important that we find out.
0:25.75 – 0:27.54 (1.8s)

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.
0:27.79 – 0:36.70 (8.9s)
7
Animals are clearly important to us, so it’s equally important that we avoid causing them unnecessary pain.
0:37.45 – 0:43.29 (5.8s)
8
For animals that are similar to us, like mammals, it's often obvious when they're hurting.
0:44.29 – 0:49.54 (5.3s)
9
But there's a lot that isn't obvious, like whether pain relievers that work on us also help them.
0:50.08 – 0:55.45 (5.4s)
10
And the more different an animal is from us, the harder it is to understand their experience.
0:55.79 – 1:00.45 (4.7s)

14
In the first, nerves in the skin sense something harmful and communicate that information to the spinal cord.
1:12.54 – 1:18.45 (5.9s)
15
There, motor neurons activate movements that make us rapidly jerk away from the threat.
1:18.75 – 1:24.37 (5.6s)
16
This is the physical recognition of harm called nociception.
1:24.37 – 1:27.95 (3.6s)
17
And nearly all animals, even those with very simple nervous systems, experience it.
1:28.25 – 1:33.33 (5.1s)
18
Without this ability, animals would be unable to avoid harm and their survival would be threatened.
1:33.33 – 1:38.45 (5.1s)
19
The second part is the conscious recognition of harm.
1:39.41 – 1:42.70 (3.3s)

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.
2:05.45 – 2:12.37 (6.9s)
24
However, we get clues from observing how animals behave.
2:13.58 – 2:17.37 (3.8s)
25
Wild, hurt animals are known to nurse their wounds, make noises to show their distress, and become reclusive.
2:18.75 – 2:25.87 (7.1s)
26
in the lab, scientists have discovered that animals like chickens and rats will self-administer pain-reducing drugs if they’re hurting.
2:26.75 – 2:34.66 (7.9s)
27
Animals also avoid situations where they’ve been hurt before, which suggests awareness of threats.
2:35.37 – 2:41.25 (5.9s)
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.
2:42.16 – 2:50.54 (8.4s)
29
But what about other types of animals, like invertebrates?
2:51.95 – 2:55.20 (3.3s)
30
These animals aren't legally protected, partly because their behaviors are harder to read.
2:55.66 – 3:01.16 (5.5s)
31
We can make good guesses about some of them, like oysters, worms and jellyfish.
3:01.87 – 3:06.62 (4.8s)
32
These are examples of animals that either lack a brain or have a very simple one.
3:07.04 – 3:11.45 (4.4s)
33
So an oyster may recoil when squirted with lemon juice, for instance, because of nociception.
3:11.87 – 3:17.62 (5.8s)
34
But with such a simple nervous system, it’s unlikely to experience the conscious part of pain.
3:18.50 – 3:23.54 (5.0s)
35
Other invertebrate animals are more complicated, though.
3:24.20 – 3:27.04 (2.8s)
36
Like the octopus, which has a sophisticated brain and is thought to be one of the most intelligent invertebrate animals.
3:27.20 – 3:33.41 (6.2s)
37
Yet in many countries, people continue the practice of eating live octopus.
3:33.95 – 3:38.87 (4.9s)
38
We also boil live crayfish, shrimp, and crabs, even though we don't really know how they're affected either.
3:39.66 – 3:46.58 (6.9s)
39
This poses an ethical problem, because we may be causing these animals unnecessary suffering.
3:46.83 – 3:52.00 (5.2s)
40
Scientific experimentation, though controversial, gives us some clues.
3:52.66 – 3:57.25 (4.6s)
41
Tests on hermit crabs show that they’ll leave an undesirable shell if they’re zapped with electricity.
3:57.70 – 4:02.95 (5.3s)
42
But stay if it’s a good shell.
4:03.29 – 4:05.16 (1.9s)
43
And octopi that might originally curl up an injured arm to protect it, will risk using it to catch prey.
4:05.41 – 4:11.37 (6.0s)
44
That suggests that these animals make value judgments around sensory input, instead of just reacting reflexively to harm.
4:12.00 – 4:19.20 (7.2s)
45
Meanwhile, crabs have been known to repeatedly rub a spot on their bodies where they’ve received an electric shock.
4:19.95 – 4:25.83 (5.9s)
46
And even sea slugs flinch when they know they’re about to receive a noxious stimulus.
4:26.33 – 4:31.37 (5.0s)
47
That means they have some memory of physical sensations.
4:31.58 – 4:34.91 (3.3s)
48
We still have a lot to learn about animal pain.
4:35.70 – 4:38.20 (2.5s)
49
As our knowledge grows, it may one day allow us to live in a world where we don’t cause pain needlessly.
4:38.62 – 4:44.91 (6.3s)

Practice Tips for This Video

To make the most of your English speaking practice when shadowing this video, consider the following tips:

  • Speaking Speed: Start by watching the video at a slower speed to fully comprehend the concepts being discussed, particularly the scientific terminology related to pain perception.
  • Accent Practice: Pay attention to Robyn J. Crook's pronunciation and intonation. Focus on mimicking her cadence to improve your own pronunciation and fluency, especially with complex words like "nociception."
  • Topic Difficulty: Since the topic involves scientific terminology, make notes of any unfamiliar terms and look them up. Try using these terms in your sentences to enhance your vocabulary.
  • Engage in Discussion: After shadowing, practice speaking with a peer or recording yourself discussing what you learned. This will help cement your understanding and boost confidence in speaking English on complex topics.

What is the Shadowing Technique?

Shadowing is a science-backed language learning technique originally developed for professional interpreter training and popularized by polyglot Dr. Alexander Arguelles. The method is simple but powerful: you listen to native English audio and immediately repeat it out loud — like a shadow following the speaker with just a 1–2 second delay. Unlike passive listening or grammar drills, shadowing forces your brain and mouth muscles to simultaneously process and reproduce real speech patterns. Research shows it significantly improves pronunciation accuracy, intonation, rhythm, connected speech, listening comprehension, and speaking fluency — making it one of the most effective methods for IELTS Speaking preparation and real-world English communication.

How to Practice Effectively on ShadowingEnglish

  1. Choose your video: Pick a YouTube video with clear, natural English speech. TED Talks, BBC News, movie scenes, podcasts, or IELTS sample answers all work great. Paste the URL into the search bar. Start with shorter videos (under 5 minutes) and content you find genuinely interesting — motivation matters.
  2. Listen first, understand the context: On your first pass, keep the speed at 1x and just listen. Don't try to repeat yet. Focus on understanding the meaning, picking up new vocabulary, and noticing how the speaker stresses words, links sounds, and uses pauses.
  3. Set up Shadowing mode:
    • Wait Mode: Choose +3s or +5s — after each sentence plays, the video pauses automatically so you have time to repeat it out loud. Choose Manual if you want full control and press Next yourself after each repetition.
    • Sub Sync: YouTube subtitles sometimes appear slightly ahead or behind the audio. Use ±100ms to align them perfectly so you can follow along accurately.
  4. Shadow out loud (the core practice): This is where the real work happens. As soon as a sentence plays — or during the pause — repeat it out loud, clearly and confidently. Don't just mouth the words: mirror the speaker's exact rhythm, stress, pitch, and connected speech. Aim to sound like a shadow of the speaker, not just a word-by-word recitation. Use the Repeat feature to drill the same sentence multiple times until it feels natural.
  5. Scale up the challenge: Once a passage feels comfortable, push your limits. Increase speed to <code>1.25x</code> or even <code>1.5x</code> to train high-speed language reflexes. Or set Wait Mode to <code>Off</code> for continuous shadowing — the most advanced and rewarding mode. Consistent daily practice of 15–30 minutes will produce noticeable results within weeks.
