Defending peers who have been bullied is often thought to put defenders at risk of becoming victimized themselves. The study investigated the concurrent and prospective associations between defending and (peer- and self-reported) victimization, and examined popularity and classroom norms as potential moderators. Participants included 4085 Finnish…

A critical skill of childhood is learning social norms. We examine whether the generic pronouns "you" and "we," which frame information as applying to people in general rather than to a specific individual, facilitate this process. In one pre-registered experiment conducted online between 2020 and 2021, children 4- to…

This study examined the developmental profiles of children's social reasoning about individual agentive and deontic concerns. Tongan children (N = 140, 47.9% male), aged 4-8 years, were given a set of mentalistic (standard theory-of-mind) and deontic reasoning tasks. On average, children found diverse desires, knowledge access, hidden emotion, and…

This three-armed randomized controlled trial examined how moral disengagement and social norms account for change in bullying behavior and their potential as targets of anti-bullying components within separate interventions among 1200 French-speaking Belgian elementary students (48% boys, 9-12 year-olds, 57 classes, nine schools) during 2018-2019…

This study examined the coevolution of prosocial and aggressive popularity norms with popularity hierarchy (asymmetries in students' popularity). Cross-lagged-panel analyses were conducted on 2,843 secondary school students (N[subscript classrooms] = 120; M[subscript age] = 13.18; 51.3% girls). Popularity hierarchy predicted relative change in…

Advanced theory-of-mind (AToM) development was investigated in three separate studies involving 82, 466, and 402 elementary school children (8-, 9-, and 10-year-olds). Rasch and factor analyses assessed whether common conceptual development underlies higher-order false-belief understanding, social understanding, emotion recognition, and…

Rule violations are likely to serve as key contexts for learning to reason about public identity. In an initial study with 91 children aged 4-9 years, social emotions and self-presentational concerns were more likely to be cited when children were responding to hypothetical vignettes involving social-conventional rather than moral violations. In 2…

To assess the flexibility of reasoning about gender, children ages 4, 6, and 8 years (N = 72) were interviewed about gender norms when different domains were highlighted. The majority of participants at all ages judged a reversal of gender norms in a different cultural context to be acceptable. They also judged gender norms as a matter of personal…

The effects of social group norms (inclusion vs. exclusion vs. exclusion-plus-relational aggression) and school norms (inclusion vs. no norm) on 7- and 10-year-old children's intergroup attitudes were examined. Children (n = 383) were randomly assigned to a group with an inclusion or exclusion norm, and to 1 of the school norm conditions. Findings…

Children and adolescents evaluated group inclusion and exclusion in the context of generic and group-specific norms involving morality and social conventions. Participants ("N" = 381), aged 9.5 and 13.5 years, judged an in-group member's decision to deviate from the norms of the group, whom to include, and whether their personal…

This study investigates possible individual and class correlates of defending and passive bystanding behavior in bullying, in a sample of 1,825 Italian primary school (mean age = 10 years 1 month) and middle school (mean age = 13 years 2 months) students. The findings of a series of multilevel regression models show that both individual (e.g.,…

Tattling, defined as the reporting to a second party of norm violations committed by a third party, is a frequent but little-studied activity among young children. Participant observation and quantitative sampling are used to provide a detailed characterization of tattling in 2 preschools (initial mean age = 4.08 years, N = 40). In these…

Toddlers were shown flawed and whole objects. Later, in a "mishap" condition, toddlers were led to believe they had damaged the examiners' valued possessions. Toddlers expressed a preference for whole objects but showed more interest in flawed objects. Manifestations of sensitivity to flawed objects were associated with behavioral and…

Children's reasons for adhering to classroom achievement, moral, and conventional norms were collected. Reasons were coded into intrinsic and extrinsic categories. Developmental change and individual consistency in offering of intrinsic reasons across domains was assessed. (PCB)

The moral realism of everyday life is neither Piaget's childlike egocentrism nor Gabennesch's reification. Natural moral law is seen by Turiel, a cognitivist, as a code of harm, rights, and justice. Other cognitivists accept codes of duty and natural order. (BC)
