Children from six cultures reliably help their peers-but in different ways.

Children aged 4 to 9 across six diverse cultures consistently help their peers through instrumental aid or information sharing, with older children increasingly providing information.

• Why it matters: Understanding peer helping behaviors across cultures fills a gap in knowledge about universal social development and the influence of cultural norms on children's social interactions.
• What they did: The study observed 336 children from Latin America, Africa, and Europe in experimental tasks, measuring spontaneous helping behaviors such as instrumental assistance and information sharing.
• The result: Findings reveal that peer helping is a universal trait with minor cultural variations, highlighting its fundamental role in human sociality and its subtle adaptation to local norms.
