Session Type: Paper Symposium
Humans are the champions of reciprocity (Nowak, 2006). Not only do we help each other, but we also return favors and motivate others to do the same. Doing so facilitates cooperation and morality, which are fundamental aspects of human sociality (e.g., Haidt, 2007; Nowak & Sigmund, 2005). However, not all favors should be encouraged or reciprocated (e.g., bribes involving public officials). Given this complexity, children face a meaningful developmental challenge when identifying whether reciprocity is expected by others, inducible, or (un)ethical. Here, four mutually informing papers examine American and German children’s understanding of reciprocity using a diverse set of experimental paradigms. Paper 1 shows that 3- to 6-year-old children are attentive to others’ past generosity and expect it to be reciprocated, both directly (as payback) and indirectly (paid forward). Paper 2 illustrates that by age 7, children are capable not only of reciprocating past generosity, but also of inducing future reciprocity (by being generous when directly interacting with potential future partners). Paper 3 demonstrates that by age 8, children also motivate future reciprocity in others even when direct interaction is not possible (by being generous with third-parties while watched by potential future partners). Paper 4 documents that by age 10, children recognize the potential of generous gifts to induce reciprocation, and rebuke gift-giving if it goes against some common good (money given to contest judges by contestants). Taken together, these findings document multiple developmental milestones that meaningfully extend our understanding of the ontogeny of humans’ preferences for reciprocity.
