The study investigated age-related trends in moral identity goal characteristics, as proposed in previous research (Krettenauer, 2022a), by modifying the Self-Importance of Moral Identity Questionnaire (Aquino & Reed, 2002). Internally and externally motivated moral identity was assessed on varying levels of abstractness for promotion…

Adults use an individual's behavior in one moral subdomain to make inferences about how they will act in another moral subdomain, reflecting a tendency to attribute underlying traits to individuals. We recruited 4- to 7-year-old children from a large city in North America to investigate their ability to generalize from one moral subdomain to…

Understanding distinctions between morality and conventions is an important milestone in children's moral development. The current meta-analysis integrated decades of social domain theory research (Smetana, 2006; Turiel, 1983) on moral and conventional judgments from early to middle childhood. We examined 95 effect sizes from 18 studies (2,707…

Although the influence of intent understanding on children's moral development has been long studied, little research has examined the influence of belief understanding on that development. In two studies we presented children with morally relevant belief vignettes to examine the extent to which they incorporate both intent and belief information…

The moral self-concept (MSC) is an early indicator of how children view themselves as moral agents. It has been proposed that an important feature of an established self-concept (SC) is sufficient coherency in how one views oneself. Furthermore, the MSC is expected to develop into a multidimensional, hierarchical construct which is stable over…

An understanding of harm is central to social and cognitive development, but harm largely has been conceptualized as physical damage or injury. Less research focuses on children's judgments of harm to others' internal well-being (emotional harms). We asked 5- to 10-year-old children (N = 456, 50% girls, 50% boys; primarily tested in Central New…

Given the value placed on honesty and the negative consequences of lying, encouraging children's truth-telling is important. The present investigation assessed honesty promotion techniques for encouraging 3-8-year-old Canadian children's (Study 1: n = 301, 54% female; Study 2: n = 229, 50% female from predominantly White middle-class samples)…

This study examined how children's and adolescents' beliefs about the distribution of wealth in society and the fairness of economic systems informed their behavior, judgments, and reasoning about access to opportunities among peers. The sample included 136 8- to 14-year-olds (47% girls, 60% White, majority middle- to higher-socioeconomic status…

Social inequalities limit important opportunities and resources for members of marginalized and disadvantaged groups. Understanding the origins of how children construct their understanding of social inequalities in the context of their everyday peer interactions has the potential to yield novel insights into when--and how--individuals respond to…

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…

What does it take know a moral truth or principle? Although testimony is an undisputed source of empirical knowledge of contingent facts, it is less clear whether it is possible to acquire "second-hand moral knowledge" (Jones, 1999; Wolff, 1998). In the present studies, 3- to 5-year-old Chinese (N = 124) and U.S. American (N = 90)…

The patterning of 160 U.S. 4- to 9-year-olds' (M = 6.23 years, SD = 1.46) moral judgments regarding physical harm, psychological harm, and unfair resource distribution transgressions were examined in separate latent profile analyses. Judgments regarding physical harm yielded a single Prototypical profile, where transgressions were judged as very…

Children encounter moral norms in several different social contexts. Often it is in hierarchically structured interactions with parents or other adults, but sometimes it is in more symmetrically structured interactions with peers. Our question was whether children's discussions of moral norms differ in these two contexts. Consequently, we had 4-…

Two experiments were conducted to investigate the influences on 4-8 year-olds' and adults' moral judgments. In both, participants were told stories from previous studies that had indicated that children's judgments are largely outcome-based. Building on recent research in which one change to these studies' methods resulted in substantially more…

Moral identity research to date has largely failed to provide evidence for developmental trends in moral identity, presumably because of restrictions in the age range of studies and the use of moral identity measures that are insensitive to age-related change. The present study investigated moral identity motivation across a broad age range (14-65…
