New research suggests that infants can recognize heroic acts before they can talk.

Japanese investigators discovered human infants recognize heroic acts from early stages of development, suggesting that our sense of justice — and likewise, adoration for heroes — may be instinctive.

The team, led by Dr. Masako Myowa of Kyoto University, showed that preverbal infants as young as six months in age find themselves drawn to figures who protect the weak.

The study, found in Nature Human Behavior, helps to explain why kids and adults alike have a never-ending love affair with superhero stories in popular culture.

“In human society, selflessly protecting the powerless is considered an act of heroic justice. But understanding this is complex,” said first author Dr. Yasuhiro Kanakogi.

“You first have to grasp the power relationship between the actors, then that the hero’s actions are favorable for the victim but not for the villain, and finally, that the hero acted deliberately.”

In a series of experiments, infants were shown animations of one geometric character chasing and bumping into another, as a third character watches from a distance.

In one version, this third party character intervenes, and in another, it escapes in another direction. When the infants were then shown real life replicas of these intervening and non-intervening characters, they were more likely to choose the intervener.

“Six-month-old infants are still in an early developmental stage, and most will not yet be able to talk. Nevertheless they can already understand the power dynamics between these different characters, suggesting that recognizing heroism is perhaps an innate ability,” said contributor Dr. David Butler, researcher and Fellow of the Japan Society for the Promotion of Science.

As infants grow, they develop a more complex understanding about justice. The research team’s next step is to track the path of this development.

“In this study, six-month-olds didn’t show a preference for intentional help over accidental help, whereas ten-month-olds did,” said Myowa.

In seeking to understand how a more complex sense of justice is fostered over time, the team ultimately sees “a possibility of contributing to solutions for serious social issues such as bullying,” she said.
