A new study by an international research team provides the first systematic, cross-cultural comparison of how children help their peers. While previous research has mainly focused on how children help adults, often within the family, peer interactions play an equally important, yet far less studied, role in children's social lives across many cultures. Researchers from the Max Planck Institute for Evolutionary Anthropology, Sapienza University of Rome, Leipzig University, the University of Portsmouth, the University of Plymouth and Duke University studied 336 children aged four to nine from six different cultural groups: Germans, Wichí (Argentina), ≠Akhoe Hai||om (Namibia), Samburu and Kikuyu (Kenya) and Quechua (Bolivia).
