Preschoolers agree to and enforce prosocial, but not selfish, sharing norms

Act generously when others do so: Majority influence on young children's sharing behavior

Children's sharing behavior is profoundly shaped by social norms within their society, and they can learn these norms by directly observing how most others share in their immediate environment. Here we systematically investigated the impact of majority influence on the sharing behavior of young Chinese children through three studies (N = 336, 168 girls). Four- and 6-year-olds were allowed to choose 10 favorite stickers and had an opportunity to engage in anonymous sharing. Before making the sharing decision, children were assigned to one of two conditions: watching a video in which three peers all shared 8 out of 10 stickers (i.e., the majority sharing condition) or making their decisions without watching the video (i.e., the control condition). Results showed that both the 4- and 6-year-old children shared more stickers in the majority sharing condition than in the control condition (Studies 1 & 2). Moreover, the influence of the majority had a stronger effect compared to the influence of a single role model. Children shared more stickers after observing three peers sharing, compared to watching one peer sharing three times (Study 2). Furthermore, children were less likely to copy the majority's non-sharing behavior when it came to giving away stickers without prosocial outcomes, which was particularly evident among 4-year-olds (Study 3). The results reveal that majority influence uniquely shapes children's sharing behavior and that children selectively follow the majority based on whether the behavior exhibits prosocial attributes.

The influence of three peers on children's sharing was stronger than that of one peer sharing three times. Four-year-olds, but not 6-year-olds, did not copy the non-sharing behavior of the majority as it did not lead to prosocial outcomes.

From what I want to do to what we decided to do: 5-year-olds, but not 3-year-olds, honor their agreements with peers

Sometimes we have a personal preference but we agree with others to follow a different course of action. In this study, 3- and 5-year-old children (N = 160) expressed a preference for playing a game one way and were then confronted with peers who expressed a different preference. The experimenter then either got the participants to agree with the peers explicitly or just shrugged her shoulders and moved on. The children were then left alone to play the game unobserved. Only the older children stuck to their agreement to play the game as the peers wished. These results suggest that by 5 years of age children's sense of commitment to agreements is strong enough to override their personal preferences.

The effect of competition on children's merit-based resource allocation: The difference between interpersonal and intergroup competition

Competition usually exists in groups in everyday interactions, but how children allocate according to competition outcomes (e.g., merit-based allocation) after intergroup competition and the difference in children's allocations of rewards between interpersonal and intergroup competition remain unclear. Children aged 3-8 years were asked to complete interpersonal or intergroup competitive games and were further asked to allocate rewards between themselves and their partners (Study 1) or between their group and the other group (Studies 2 and 3) and to reason about their decisions. We found that after interpersonal competition, children tended to conduct merit-based allocations when they won but were more inclined to conduct equal allocations when they lost; after intergroup competition, children were more inclined to make equal allocations regardless of whether they won or lost, only less than half of children followed meritorious principles. However, children conducted more merit-based allocations with age after both interpersonal and intergroup competitions. In addition, children showed less bias towards their own side after intergroup competition than after interpersonal competition. Finally, they demonstrated an earlier proclivity towards being influenced by winning outcomes than by losing outcomes after interpersonal competition, whereas a converse tendency was found after intergroup competition.

Varieties of normative understanding and their relation to sharing behavior in preschool children

Children increasingly appreciate normative obligations and share resources across the preschool years. But the internal structure and behavioral relevance of normative expressions in the context of sharing-that is, the relation with children's own sharing behavior-remains disputed. Here, 4- to 6-year-old children (N = 90; 37 female) observed protagonists sharing or not sharing resources. As measures of normative expressions, children's evaluation, punishment acceptability, non-costly punishment, and costly punishment of the protagonists as well as their moral self-concept were assessed. To measure actual prosocial behavior, children had the possibility to share resources. A factor analysis revealed that the variety of normative expressions constitutes two distinct factors: normative representation (evaluation and hypothetical punishment) and norm enforcement (actual non-costly and costly punishment). Children's moral self-concept was the only normative expression that related to sharing behavior. Person-centered analyses suggest some consistency in individual differences across normative and prosocial development, with normative expressions and sharing behavior being aligned for some children on a low level and for some children on a high level. This study advances our understanding of early normative development and highlights the internal structure of normative stances during the preschool years.

Normative views and resource distribution behavior in childhood: Dissociated at the group level, but associated at the individual level

Previous research debated whether and to which extent normative views and own resource distribution behavior in childhood are dissociated or aligned. The present study aims to advance this debate by examining the relation from two different methodological viewpoints within the same study. Here, 4–6-year-old children’s ( N = 91) normative views and distribution behavior when confronted with a rich friend and a poor non-friend were assessed. Children’s spontaneous protest and affirmation toward distributors, evaluations, and punishment judgments served as normative indicators. Looking at average normative views and behavior, preschoolers held a normative view toward rectifying inequalities while favoring the rich friend themselves. Looking at the consistency of interindividual differences, preschooler’s normative view correlated with behavior. The study highlights that the relation between normative views and behavior is characterized by both dissociation and coherence.
