The present study sought to evaluate the reproducibility of prominent findings stated by Fehr et al. in their developmental resource allocation experiment "Egalitarianism in Young Children", published in 2008. The experiment involved children making decisions about distributing sweets between themselves and either an in-group or an…

Third-party punishment has been regarded as an important mechanism to promote fairness. Although previous research has shown that children aged 6 and older punish unfair behaviors at a personal cost, it is unknown whether they actually intend to establish equality or whether equality is a mere byproduct of punishment. In this preregistered study,…

Studies on development and fairness judgments in resource allocations have mainly addressed the distribution of reward. However, the distribution of responsibility also requires exploration in the context of research on development and distributive justice. For an integrated understanding of reward and responsibility distributions, we briefly…

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…

The ability to distinguish between mere equality in resource distributions and fairness based on a broader range of contextual factors is of paramount importance in social decision making and is a critical component of morality. Children's developmental shift from viewing inequality as a dichotomous moral issue toward a more nuanced understanding…

This study examined young children's contact with individuals of high-wealth and low-wealth backgrounds and their behavior toward peers of these backgrounds in a resource distribution task. The sample included 72 ethnically diverse higher income children (M[subscript age] = 6.68 years, SD = 0.98 years). Contact with individuals of low-wealth…

Three experiments (total N = 140) tested the hypothesis that 5-year-old children's membership in randomly assigned "minimal" groups would be sufficient to induce intergroup bias. Children were randomly assigned to groups and engaged in tasks involving judgments of unfamiliar in-group or out-group children. Despite an absence of information…
