Remember your first summer camp, meeting a new group of children for the first time? Who would you want to be friends with? Who would you share your breakfast with? One answer is: the ones who speak the same way you do. Researchers from the Max Planck Institute for Psycholinguistics in Nijmegen and the Max Planck Institute for Evolutionary Anthropology in Leipzig have found that accent is an early developing guide to children’s social preferences. The study by Emma Cohen and Daniel Haun was published in Evolution and Human Behavior on March 14.
