Infants as young as ten months old express sympathy for others in distress in non-verbal ways, according to a new research.
Infants at this age are known to assign goals and intentions to geometric figures; hence the researchers used a series of animated sequences to test infants' responses to aggression.
In their experiments, researchers showed infants an aggressive 'social interaction' between a blue ball that attacked and violently crushed a yellow cube and found that the babies preferentially reached for the victim rather than the aggressor.
Infants' behaviour remained consistent when the roles of the shapes were reversed and when a neutral, non-aggressive shape was introduced in the video, suggesting that their preference for the victim was not out of fear of the aggressive shape, according to Yasuhiro Kanakogi and colleagues from Kyoto University and Toyohashi University of Technology, Japan.
"Ten-month olds not only evaluate the roles of victims and aggressors in interactions but also show rudimentary sympathy toward others in distress based on that evaluation," the authors said.
"This simple preference may function as a foundation for full-fledged sympathetic behaviour later on," they added.
The study was published in the journal PLOS ONE.
