Early Understanding of Normativity and Freedom to Act in Turkish Toddlers

Children across societies enforce conventional norms but in culturally variable ways

Individuals in all societies conform to their cultural group's conventional norms, from how to dress on certain occasions to how to play certain games. It is an open question, however, whether individuals in all societies actively enforce the group's conventional norms when others break them. We investigated third-party enforcement of conventional norms in 5- to 8-y-old children (n = 376) from eight diverse small-scale and large-scale societies. Children learned the rules for playing a new sorting game and then, observed a peer who was apparently breaking them. Across societies, observer children intervened frequently to correct their misguided peer (i.e., more frequently than when the peer was following the rules). However, both the magnitude and the style of interventions varied across societies. Detailed analyses of children's interactions revealed societal differences in children's verbal protest styles as well as in their use of actions, gestures, and nonverbal expressions to intervene. Observers' interventions predicted whether their peer adopted the observer's sorting rule. Enforcement of conventional norms appears to be an early emerging human universal that comes to be expressed in culturally variable ways.

Three-Year-Olds' Reactions to a Partner's Failure to Perform Her Role in a Joint Commitment

When children make a joint commitment to collaborate, obligations are created. Pairs of 3-year-old children (N = 144) made a joint commitment to play a game. In three different conditions the game was interrupted in the middle either because: (a) the partner child intentionally defected, (b) the partner child was ignorant about how to play, or (c) the apparatus broke. The subject child reacted differently in the three cases, protesting normatively against defection (with emotional arousal and later tattling), teaching when the partner seemed to be ignorant, or simply blaming the apparatus when it broke. These results suggest that 3-year-old children are competent in making appropriate normative evaluations of intentions and obligations of collaborative partners.

From imitation to implementation: How two- and three-year-old children learn to enforce social norms

Young children enforce social norms from early on, but little research has examined how this enforcement behaviour emerges. This study investigated whether observing an adult's norm enforcement influences children's own enforcement of that norm compared with observing an action demonstration without enforcement. Additionally, children experienced enforcement either following their own (second-party) or a third-party's transgression (N = 120). Results revealed that observing enforcement increased two- and three-year-old children's protest against the sanctioned action regardless of second- or third-party context. However, only three-year-olds generalized their enforcement to a novel action not matching the norm, whereas two-year-olds only protested against the previously sanctioned action. Importantly, without any enforcement demonstration, two-year-olds rarely protested at all while three-year-olds did so quite frequently. Thus, providing an opportunity to imitate enforcement seems to give rise to enforcement behaviour in two-year-olds while three-year-olds already understand normative implications following a variety of cues and even apply norm enforcement without any demonstration of how to do it. Statement of contribution What is already known on this subject? Children conform to social norms from early in development. Young children from 2 to 3 years of age also enforce social norms on third parties. What does this study add? Observing enforcement by an adult increases two- and three-year-olds' protest against the sanctioned action. It does not matter whether children experienced enforcement on their own or a third party's action. Three-, but not two-year-olds, generalize their enforcement to novel actions that do not match the norm.
