People's curiosity about others often reflects their concepts of others. This research examined the amount and types of information Israeli children and adults seek about in-group and out-group members. Children (kindergarteners and 2nd graders) and adults (N = 219) from a numerical minority group (Israeli Arabs; Study 1) and a numerical majority group (Israeli Jews; Study 2), were asked what they would like to know about individuals from three social groups: their in-group (Arabs or Jews, respectively), a conflict out-group (Jews or Arabs, respectively), and a non-conflict out-group (Scots). Results showed that although the target's social group did not affect the amount of information participants requested, it did affect information content. Namely, Arab participants requested more psychological information about the conflict out-group than the other groups, whereas Jewish participants requested more social identity information about both conflict and non-conflict out-groups than the in-group. The findings highlight how group membership and social status (reflecting numerical group size, dominance, and broader social standing) shape the nature of information children and adults seek about others.

ABSTRACT The out‐group homogeneity effect has been found to contribute to adults' inter‐group biases. Three studies examined whether 5‐ and 8‐year‐old Arab (i.e., minority) children in Israel also manifest this effect (March 2017–January 2020). Arab children from different religious affiliations and social environments ( N = 272, 54% females) were asked to choose either a homogeneous or a heterogeneous sample of group members to infer if a given property (biological or psychological) was true of a whole group: either the participant's in‐group (Arabs) or out‐group (Jews). Overall, differently from Jewish (i.e., majority) Israeli children, Arab children did not exhibit the out‐group homogeneity effect. Nevertheless, there were indications that religious affiliation, social environment, and group identification affected children's responses.

The current study investigated how U.S. adults (N = 99) and 5- and 6-year-old children (N = 112) use statistical information in their social partner choices. We found that children integrated base rate information (the distribution of traits within groups) and individual-level statistical information (the frequency of an individual's past behaviors) in their partner choices, but adults only relied on the individual-level statistical information and neglected base rate information. In addition, adults and children were affected by non-statistical information: Adults showed risk-seeking and risk-averse tendencies, and children showed only risk-seeking tendencies in their partner choices. These findings provide evidence that both statistical and non-statistical information affect social decisions, and adults and children are influenced by each type of information in distinct ways. The current study suggests future directions to further investigate the role of statistical learning in our social cognition and to develop a unifying account of how non-statistical information interacts with statistical information in our social decisions.

The present research explored whether children manifest intergroup biases in their choice of informants from in- versus out-groups. We conducted two studies among Israeli Jewish and Arab children aged 5- and 8-year-old (N = 260; 51% girls, 49% boys). Study 1 served as a baseline with nonsocial targets of information, whereas Study 2 had people as targets. We examined biases in three respects: assessment of informants' expertise, preference for informants, and acceptance of informants' advice. Results revealed intergroup biases in children's choices of informants in all three respects, particularly when learning about people, and among younger and minority group children. The findings highlight how epistemic and social identity cues affect children's informant's choice. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

The Developing Belief Network is a consortium of researchers studying human development in diverse social-cultural settings, with a focus on the interplay between general cognitive development and culturally specific processes of socialization and cultural transmission in early and middle childhood. The current manuscript describes the study protocol for the network’s first wave of data collection, which aims to explore the development and diversity of religious cognition and behavior. This work is guided by three key research questions: (1) How do children represent and reason about religious and supernatural agents? (2) How do children represent and reason about religion as an aspect of social identity? (3) How are religious and supernatural beliefs transmitted within and between generations? The protocol is designed to address these questions via a set of nine tasks for children between the ages of 4 and 10 years, a comprehensive survey completed by their parents/caregivers, and a task designed to elicit conversations between children and caregivers. This study is being conducted in 39 distinct cultural-religious groups (to date), spanning 17 countries and 13 languages. In this manuscript, we provide detailed descriptions of all elements of this study protocol, give a brief overview of the ways in which this protocol has been adapted for use in diverse religious communities, and present the final, English-language study materials for 6 of the 39 cultural-religious groups who are currently being recruited for this study: Protestant Americans, Catholic Americans, American members of the Church of Jesus Christ of Latter-day Saints, Jewish Americans, Muslim Americans, and religiously unaffiliated Americans.

The present research investigated the effect of ethnic-national identity on intergroup attitudes among Israeli children. Between 2019 and 2020, 136 Arab Muslim and 136 Jewish 5- and 10-year-olds (boys and girls) participated in one of four ethnic-national identity conditions: ingroup, outgroup, common identity, and control. In each condition, participants were described a city whose residents were defined according to the condition. Then, children were asked to "release" positive and negative animals to an ingroup city, an outgroup city, or a zoo. The results showed that highlighting a common identity improved attitudes across all children, but effect of ingroup and outgroup emphases varied between Jewish and Arab children. These results highlight the different dynamics of social identities among majority and minority children.

Adults tend to construe members of their group as "unique individuals" more than members of other groups. This study investigated whether infants exhibit this tendency, even in regard to unfamiliar arbitrary groups. Ninety-six White 1-year-olds were assigned to an Ingroup, Outgroup, or No-Group condition, based on whether or not they shared two preferences (food and shirt color) with women appearing on video sequences. In the critical trial, infants saw two women (Ingroup, Outgroup, or No-Group) - one at a time - appearing from behind a curtain. The curtain opened to reveal only one woman. Infants in the Ingroup condition looked longer at this display than infants in the other two conditions. This suggests that infants in the Ingroup condition had a stronger expectation than those in the other two conditions that there would be two women behind the curtain. In other words, infants individuated in-group members more than out-group members.

Intergroup bias - the preferential attitudes one holds towards one's social group - is a ubiquitous socio-cognitive phenomenon. In fact, studies show that already in the first months of life, infants manifest a preference for members of their own social group. This points to the possibility of inborn mechanisms involved in social group cognition. Here we assess the effect of a biological activation of infants' affiliative motivation on their social categorization capacity. In a first visit to the lab, mothers self-administered either Oxytocin (OT) or placebo (PL) via a nasal spray and then engaged in a face-to-face interaction with their 14-month-old infants, a procedure previously shown to increase OT levels in infants. Infants then performed a racial categorization task presented on an eye-tracker. Mothers and infants returned a week later and repeated the procedure while self-administering the complementary substance (i.e., PL or OT, respectively). In total, 24 infants completed the two visits. We found that whereas infants in the PL condition on the first visit exhibited racial categorization, infants in the OT condition in their first visit did not. Moreover, these patterns remained a week later despite the change in substance. Thus, OT inhibited racial categorization when infants first encountered the to-be-categorized faces. These findings highlight the role of affiliative motivation in social categorization, and suggest that the neurobiology of affiliation may provide insights on mechanisms that may be involved in the downstream prejudicial consequences of intergroup bias.

This study evaluated the effectiveness of a vicarious contact intervention program for improving knowledge and attitudes of Jewish-Israeli secular and religious children regarding their ingroup and three outgroups: secular/religious Jews, Ethiopian-descendant Jews, and Arabs. One hundred and nine kindergartners participated in a four-week intervention, in which experimenters introduced to them four persona dolls representing the different groups. Accompanied by stories, children were exposed to the dolls' individual and group characteristics, and to positive encounters between the dolls. A pre- and post-test battery assessed the intervention's effects on children's intergroup knowledge and attitudes. Findings revealed an increase in children's knowledge of the groups, improvements in religious children's attitudes towards Arabs, and in both secular and religious children's willingness to sit closer to Ethiopian-descendant children. These findings highlight the potential of indirect contact for reducing intergroup bias in young children living in multicultural and conflict-ridden societies.

Children's intergroup attitudes arguably reflect different construals of in- and out-groups, whereby the former are viewed as composed of unique individuals and the latter of homogeneous members. In three studies, we investigated the scope of information (individual vs. category) Jewish-Israeli 5- and 8-year-olds prefer to receive about "real" in-group ("Jews") and out-group members ("Arabs" and "Scots") (Study 1, N = 64); the scope of information Jewish and Arab Israeli 8-year-olds prefer to receive about minimal in- and out-groups (Study 2, N = 64); and how providing such information affects children's intergroup attitudes (Study 3, N = 96). The main findings were that (a) 8-year-olds requested category information more about out-groups than in-groups, and vice-versa regarding individual information-for both, "real" and minimal groups, and (b) providing individual information about a "conflict" out-group reduced attitudinal biases. These findings highlight children's differential construal of in- and out-groups and suggest ways for remedying biases toward out-groups.

Recent studies indicate that a preference for people from one's own race emerges early in development. Arguably, one potential process contributing to such a bias has to do with the increased discriminability of own- vs. other-race faces-a process commonly attributed to perceptual narrowing of unfamiliar groups' faces, and analogous to the conceptual homogenization of out-groups. The present studies addressed two implications of perceptual narrowing of other-race faces for infants' social categorization capacity. In Experiment 1, White 11-month-olds' (N = 81) looking time at a Black vs. White face was measured under three between-subjects conditions: a baseline "preference" (i.e., without familiarization), after familiarization to Black faces, or after familiarization to White faces. Compared to infants' a priori looking preferences as revealed in the baseline condition, only when familiarized to Black faces did infants look longer at the "not-familiarized-category" face at test. According to the standard categorization paradigm used, such longer looking time at the novel (i.e., "not-familiarized-category") exemplar at test, indicated that categorization of the familiarized faces had ensued. This is consistent with the idea that prior to their first birthday, infants already tend to represent own-race faces as individuals and other-race faces as a category. If this is the case, then infants might also be less likely to form subordinate categories within other-race than own-race categories. In Experiment 2, infants (N = 34) distinguished between an arbitrary (shirt-color) based sub-categories only when shirt-wearers were White, but not when they were Black. These findings confirm that perceptual narrowing of other-race faces blurs distinctions among members of unfamiliar categories. Consequently, infants: a) readily categorize other-race faces as being of the same kind, and b) find it hard to distinguish between their sub-categories.

Decades of research on adults’ inter-group attitudes document that people tend to favor in-groups over outgroups (Allport, 1954; Tajfel, 1982). In fact, many inter-group biases originally investigated in adults, have also been documented in children. From preschool-age, children reliably prefer in-groups over out-groups, more readily associate their in-groups with positive attributes, and do so even in cases where group membership is established on arbitrary grounds, such as the color of clothing (Aboud, 2003; Benozio & Diesendruck, 2015; Bigler et al., 1997). Work in adult social psychology indicates that a potential foundation for inter-group attitudinal biases relates to difference in behavioral attribution and explanation. For instance, out-group members’ behaviors are more often Received: 24 June 2020 | Revised: 25 November 2020 | Accepted: 25 November 2020 DOI: 10.1111/sode.12499

Do children construe leaders as individuals whose position of power entails primarily more responsibility or more entitlement, compared with nonleaders? To address this question, 5-year-old children ( n  = 128) heard a story involving a hierarchical dyad (a leader and a nonleader) and an egalitarian dyad (two nonleaders), and then assessed protagonists’ relative contributions to a collaborative endeavor (Experiments 1 and 2) or relative withdrawals from a common resource pool earned jointly (Experiment 3). Children expected a leader to contribute more toward a joint goal than its nonleader partner, and to withdraw an equal share (not more) from a common pool. Children thus gave evidence that they construed leaders as more responsible, rather than more entitled, relative to nonleaders.

The tendency to view groups as constituting essentially different categories emerges early in development. To date, most attempts at understanding the origins of this tendency have focused on cognitive processes. Drawing from social-psychological and evolutionary theory, I propose that motivations—in particular, a need to belong—may be foundational for the development of social essentialism. I review evidence indicating that this perspective not only is developmentally plausible but also may explain children’s tendency to consider intentional behaviors performed by in-group members as normative.

Predicting others’ behavior is critical for everyday social interactions. Research indicates a development in the cues children rely on in making such predictions. The present studies investigated whether 5- and 8-year-olds from Germany and Israel (N = 136) rely on group preferences for predicting others’ behavior, and whether their reliance on group preferences vary for in- and outgroups. Children were asked to predict the behavior of in- and outgroup members, while presented with conflicting information about a group’s and an individual’s preference. The main finding was that in both Germany and Israel, children – especially 8-year-olds – systematically predicted that novel group members would follow a group preference, but that an individual would maintain his/her own preference. Moreover, in neither country were children affected by the group membership of the target individuals. These studies reveal the protracted development of children’s capacity to negotiate multiple sources of information for predicting people’s behaviors.

The tendency to essentialize social groups is universal, and arises early in development. This tendency is associated with negative intergroup attitudes and behaviors, and has thus encouraged the search for remedies for the emergence of essentialism. In this vein, great attention has been devoted to uncovering the cognitive foundations of essentialism. In this chapter, I suggest that attention should also be turned toward the motivational foundations of essentialism. I propose that considerations of power and group identity, but especially a "need to belong," may encourage children's essentialization of social groups. Namely, from a young age, children are keen to feel members of a group, and that their membership is secure and exclusive. Essentialism is the conceptual gadget that satisfies these feelings. And to the extent that groups are defined by what they do, this motivated essentialism also impels children to be adamant about the maintenance of unique group behaviors.

Funding information This research was conducted with the support of MOFET Institute Abstract One of the key factors contributing to the development of negative attitudes toward out‐groups is lack of knowledge about them. The present study investigated what type of information 3‐ to 4‐ and 5‐ to 6‐ year‐old Jewish Israeli chil‐ dren (N = 82) are interested in acquiring about unfamiliar in‐ and out‐group individuals, and how providing children with the requested information affects their intergroup at‐ titudes. Children were shown pictures of individuals from three groups—an in‐group (“Jews”), a “conflict” out‐group (“Arabs”), and a “neutral” out‐group (“Scots”)—and were asked what they would like to know about them. The ex‐ perimenter responded by either answering all of children's questions, half of the questions, or none. Children's atti‐ tudes toward the groups were also assessed. It was found that children asked the most questions in regard to conflict out‐group individuals. Moreover, the older age group asked more questions regarding the psychological characteristics, and fewer questions regarding the social identity, of the conflict out‐group than of the other two groups. Finally, full provision of information improved attitudes toward the groups, especially among 3‐ to 4‐year olds, and especially regarding the conflict out‐group. These findings have impli‐ cations for understanding the sources of intergroup biases, and for developing interventions to reduce them.
