[EN VIDÉO] Animal intelligence: An elephant would know about its body
The Asian elephant passed the intelligence test that a two-year-old doesn’t pass: you can’t pull a carpet if you’re on it. An experiment conducted by Think Elephants International shows that the elephant is aware of its own body, which was also shown by the mirror test. A rare ability in the animal kingdom.

The pig is the smartest animal on the farm. Here the idea is abandoned. At some points, he can compete with a dog, a dolphin, or even a chimpanzee. He knows how to recognize characters. And he has a memory. Good memory. Anything you need learn to play video games.

The pig, as we have already mentioned, also successfully passes the famous test mirror. Or, at least, a variant specially developed for it by researchers. Proof that the pig has self-awareness. This gives hope that he may be aware of others. Scientists have already managed to show that the pig can deceive its enemy. Understand the pig he doesn’t know. Demonstration of what might be called certain form of intelligence Machiavellian » to hide your food. A pig, on the other hand, behaves quite differently in the presence of a familiar relative. whom he trusts.

So the pig has a personality. He feels emotions. And he expresses them through vocalizations that other pigs can decipher. The trouble is that we, ordinary people, we don’t speak… swine. It’s a shame. Because understanding the emotions expressed by a pig can allow breeders to improve their well-being. Imagine yourself on translation softwarechoose language “pig” and immediately receive a translation of the vocalization into French. This is a small part of what the researchers managed to develop. A tool that deciphers the sounds made by pigs to help breeders better understand the emotions behind them.

translate pig language

Among them is Kokoriko! French explorers. First, they recorded thousands of vocalizations from pigs of all ages and in twenty different situations, from birth to slaughter and various types of breeding, to produce about 7,500 good quality recordings of both positive and negative emotions.

Then it was necessary to mobilize the experience of ethologists and bioacoustics. First for classify emotions that they have been studying for about thirty years on animals according to the situations they experience. Their assessment was supplemented, if possible, with data on the heart rate of pigs. Bioacoustics, for their part, had to more technically analyze the acoustic structure of vocalizations, their frequency, purity, etc.

It follows from this work that negative emotions preferentially require high-pitched vocalizations such as screaming. On the other hand, low frequency vocalizations such as grunts can reflect both positive and negative emotions. But, for example, in the first case, vocalizations are shorter and have weak amplitude fluctuations.

To capitalize on their findings, the researchers called forintelligence…artificial, this time. They have developed a system that, compared to the first 7500 classified sounds, is able to translate in more than 90% of cases valence the emotionality of an emotion expressed – whether positive or negative emotion – through vocalization, but also to show, in more than 80% of cases, the situation in which this emotion arose. Technology can help signal a problem to breeders. Or let them improve the well-being of their pigs by providing them with new games.

So, even if we need an intermediary to understand this, now we can make sure of it. Pig… not so stupid!
