People rely on reputational information communicated via gossip when deciding about with whom to cooperate, whom to believe, and whom to trust. In two studies, we investigated whether 5- and 7-year-old children trust in gossip when determining a course of action. In Study 1, 5- and 7-year-old German-speaking peer dyads (N = 64 dyads, 32 female…

Moral justifications work, when they do, by invoking values that are shared in the common ground of the interlocutors. We asked 3- and 5-year-old peer dyads (N = 144) to identify and punish norm transgressors. In the moral condition, the transgressor violated a moral norm (e.g., by stealing); in the social rules condition, she/he violated a…

Group decision making should be particularly beneficial when group members share unique information, because then a group can make a better decision than each group member alone. This study examined how elementary-school children share unique information during group decision making. Seventy-nine groups of 3 same-sex and same-age 7- and 9-year-old…

The larger the economic inequality in access to opportunities children…

Children collaborated in planning imaginary errands with novice peers, trained peers, or untrained adults. Collaborative planning of dyads with trained peers and with adults was equally sophisticated. Children who worked with adults planned better in posttests than those who collaborated with trained peers. (BC)
