Young children are able to discern immoral acts to punish those who commit them. This may show that morality, in human beings, does not depend only on the social and cultural context, but is innate.
But how to prove if, young children still can not talk to communicate? By monitoring their gaze.
According to a study published in Nature Human Behavior, when a young child sees someone doing something he or she does not like, he or she uses his or her gaze to identify and perhaps even punish.
For the experiment, the researchers investigated physical aggression by displaying episodes of beatings, also because, in the past, other research has shown that young children can distinguish the victim from the aggressor, displaying disgust towards the latter.
The children were then shown a video with two characters beating each other. Through a system of tracking their vision, the little ones could control the actions of both. If they watched a character for a certain period of time, he would end up disappearing from the video. At the end of the experiment, which was repeated with several variants, it turned out that the children had eliminated a much larger number of aggressors than the victims, precisely by observing them for a long time.
Psychologist Yasuhiro Kanakogi of Osaka University in Japan concludes: “ Our study shows that verbal children have chosen to punish the aggressor by following him with their gaze. And since this behavior is present in the young, humans are likely to have acquired moral behaviors during the course of evolution. "Punishing antisocial behavior may have evolved as an important element of human cooperation."
