This is a very simple and elegant study that shows that toddlers and preschoolers appreciate how ownership affects emotions. The researchers used a couple of straightforward scripts to present children with situations involving transgression of ownership rights, and to ask about the emotions elicited in the characters. For example, a character left a teddy bear on a bench and, upon returning, found her teddy bear (vs. someone else’s teddy bear, in the other condition) missing. In another situation, a character saw another character using her toy.

The researchers concluded that preschoolers and toddlers appreciate how ownership influences emotions.  Children understood that an owner would be more saddened by the disappearance of an object belonging to her as compared with the disappearance of someone else’s property.

The authors believe these findings are “striking” because in two (out of three) experiments the violation of ownership rights was harmless and did not involve an overtly negative outcome. In my words, children understand that the characters are sad or mad not because of an “objective” damage, harm or loss, but because of the violation of their rights. A child might be upset by the very fact that someone is touching her toy. This territoriality is at the core of the phenomenon of ownership. The paper seems to suggest that, already at two, children master the fundamentals of the institution of ownership. They know the rules of the game.

The authors also think their results are significant because “few previous studies show that 2-year-olds can predict emotions”, and because “no previous studies found that 2-year-olds are sensitive to other people’s ownership rights.” In particular, they refer to a well-known paper by Rossano, Rakoczy, & Tomasello (2011) that claims that 3-year-olds, but not 2-year-olds, defend third-person ownership rights.
