New paper published in the special issue on Children’s teaching, Young Children’s Transmission of Information following Self-discovery and Instruction. Our study showed that children at the age of 2 tend to preferentially share information with someone who is less knowledgeable than them after they have been instructed themselves, rather after having learned it through independent exploration. However, 5-year-olds did not show such preference and tended to teach information both self-discovered and taught to them.
