Your newborn can pretty well identify who is his/her friend or foe even before he/she acquires language skills or get matured enough to be able to make the distinction.
According to a new study on infant cognition by University of Chicago, even nine-month-old infants can engage in reasoning about whether the people they observe are friends or foes.
“This is some of the first evidence that young infants are tracking other people's social relationships,” said Amanda L. Woodward, the William S. Gray Professor of Psychology and co-author of the study.
