'Transmission of emotion', which reads emotions from expressions and gestures and inherits them unconsciously, also occurs among crows

Human emotions can be transmitted from person to person, and in particular, people who are influential sometimes ' have peace of mind with others,' or conversely, 'make people feel uneasy while doing nothing.' Researchers have announced that there is a possibility that this kind of emotional transmission may occur in crows.

Ravens can transmit negative emotions from one another, just like humans

Humans are living creatures that use verbal and nonverbal tools to communicate in a very complex way. Human beings have made social interaction efficient by reading the other party's emotions and ideas in various ways, and have flourished on the earth. For example, reading 'pain' from the other person's face will help you to immediately know that 'a crisis may be nearby' as well as 'seeking for help.'

Also, in the past researches, it has also been known that when looking at the other person's face, people can inherit that face without noticing it. In other words, we humans share emotions in our relationships with people. One example of such unconscious 'infection of emotions' is the enthusiasm and collective panic in watching sports.

In a new paper, researchers from the University of Vienna and the University of Zurich have announced that 'transmission of emotions' will occur not only among humans but also among crows. The high intelligence of crows has been recognized in several studies so far. Researchers experimented with the idea that crows with high intelligence and social behavior are not afraid that emotional transmission may occur.

'It's easier to understand negative emotions than positive ones,' the experiment found out to what extent crows' negative emotions are transmitted. The researchers first made 16 crows in pairs, giving them a box of favorite cheese and an empty box. Then, after the crows checked the contents of each box, the two birds were moved to different places, and one crow was given a 'third box'.

This third box contained crow's favorite dry dog food or carrots that are not a favorite. This is a method known as cognitive bias testing, where one crow transferred to another location could actually see how the other reacted to food but was actually in the box The food could not know anything. After that, I presented the third box in the same way to the crows who saw the reaction of the pair crows, and if the pair crows showed a negative reaction to the food, the crows more carefully boxed It was shown to examine.

Researchers conclude from this behavior that 'negative emotions may be transmitted even in the case of crows.' The crow, who was watching the crows showing no negative emotions, was not skeptical about the third box.

However, studies investigating similar things have concluded that emotions can be transmitted to monkeys and dogs as well.
