Maladaptive but malleable: Gender-science stereotypes emerge early but are modifiable by language.

Gender-science stereotypes emerge early in childhood, but little is known about the developmental processes by which they arise. The present study tested the hypothesis that language implying scientists are a special and distinct kind of person contributes to the development of gender-science stereotypes, even when it does not communicate stereotypic content. One cross-sectional and two longitudinal studies with racially and geographically diverse children (primarily from the United States; ages 4-5; N = 872, tested 2020-2022) revealed that gender stereotypes about science versus art (a) emerge before elementary school, (b) arise from commonplace identity-emphasizing language, especially among girls, and (c) can be durably disrupted by subtle changes to language.

How Culture Shapes the Early Development of Essentialist Beliefs.

People represent many categories and their features as determined by intrinsic essences. These essentialist beliefs reflect biased views of the world that can hinder scientific reasoning and contribute to social prejudice. To consider the extent to which such essentialist views originate from culturally-situated processes, the present study tested the developmental trajectories of essentialist beliefs among children growing up in the United States and China (N = 531; ages 3-6).

How generic language shapes the development of social thought.

Generic language, that is, language that refers to a category as an abstract whole (e.g., 'Girls like pink') rather than specific individuals (e.

Infants' visual attention to own-race and other-race faces is moderated by experience with people of different races in their daily lives.

Infants sometimes differentially attend to faces of different races, but how this tendency develops across infancy and how it may vary for infants growing up with different exposure to racial diversity remain unclear. The present study examined the role of experiences with racial diversity on infants' visual attention to different racial groups (specifically own-race vs. other-race groups) in the first year of life via a large-scale study of infants (N = 203; Mage = 6.

Does racial diversity affect White children's racial bias and reasoning? Depends on where they live and how their social world is structured.

By 4 years of age, White children from across the United States begin to exhibit an awareness of racial inequalities, along with in-group preferences for other White children. The present study explored how the size and racial diversity of White children's social network (e.g.

Structural explanations for inequality reduce children's biases and promote rectification only if they implicate the high-status group.

Children begin to participate in systems of inequality from a young age, demonstrating biases for high-status groups and willingly accepting group disparities. For adults, highlighting the causes of inequality (i.e.

The effect of group status on children's hierarchy-reinforcing beliefs.

Members of advantaged groups are more likely than members of disadvantaged groups to think, feel, and behave in ways that reinforce their group's position within the hierarchy. This study examined how children's status within a group-based hierarchy shapes their beliefs about the hierarchy and the groups that comprise it in ways that reinforce the hierarchy. To do this, we randomly assigned children (4-8 years; N = 123; 75 female, 48 male; 21 Asian, 9 Black, 21 Latino/a, 1 Middle-Eastern/North-African, 14 multiracial, 41 White, 16 not-specified) to novel groups that differed in social status (advantaged, disadvantaged, neutral third-party) and assessed their beliefs about the hierarchy.

A developmental investigation of group concepts in the context of social hierarchy: Can the powerful impose group membership?

Group membership is not always voluntary and can be imposed within a social context; moreover, those with power disproportionately shape group membership. We asked if children and adults view group membership as imposed by the powerful. We undertook four studies (465 children ages 4-9, 150 adults): Studies 1-2 used novel minimal groups; Study 3 used 'cool' and 'uncool'; Study 4 used novel ethnic groups.

Speaking of Kinds: How Correcting Generic Statements can Shape Children's Concepts.

Generic language (e.g., "tigers have stripes") leads children to assume that the referenced category (e.

Developmental origins of anti-Black bias in White children in the United States: Exposure to and beliefs about racial inequality.

Anti-Black racism remains a pervasive crisis in the United States. Racist social systems reinforce racial inequalities and perpetuate prejudicial beliefs. These beliefs emerge in childhood, are difficult to change once entrenched in adolescence and adulthood, and lead people to support policies that further reinforce racist systems.

Stereotypes as prototypes in children's gender concepts.

How do gender stereotypes shape prototypes across development? In the current pre-registered study with children ages 3- to 10-years-old and adults (N = 257), participants made judgements about which members of gender categories (boys and girls) and animal categories (for comparison) were the most representative and informative about their kinds, using simplified scales of five category members varying on a stereotypical feature (e.g., girls wearing more or less pink).

Parents' Political Ideology Predicts How Their Children Punish.

From an early age, children are willing to pay a personal cost to punish others for violations that do not affect them directly. Various motivations underlie such "costly punishment": People may punish to enforce cooperative norms (amplifying punishment of in-groups) or to express anger at perpetrators (amplifying punishment of out-groups). Thus, group-related values and attitudes (e.

The influence of linguistic form and causal explanations on the development of social essentialism.

Generic descriptions of social categories (e.g., boys play baseball; girls have long hair) lead children and adults to think of the referenced categories (i.

How children's media and teachers communicate exclusive and essentialist views of science and scientists.

Language that uses noun labels and generic descriptions to discuss people who do science (e.g., "Let's be scientists! Scientists discover new things") signals to children that "scientists" is a distinctive category.

Social essentialism in the United States and China: How social and cognitive factors predict within- and cross-cultural variation in essentialist thinking.

People intuitively view some social groups (such as Black people, Muslims, and women) as having biological underpinnings and discrete boundaries. Essentialist beliefs about social groups shape how people view themselves and others, leading to a number of negative social consequences. Whereas previous research has demonstrated variations in social essentialism within some Western societies, less is known about how social essentialism manifests in East Asian cultures that have well-documented differences in social values and cognitive styles from Western cultures.

How race and gender shape the development of social prototypes in the United States.

The present studies examined how gender and race information shape children's prototypes of various social categories. Children ( = 543; = 5.81, range = 2.

Who is a typical woman? Exploring variation in how race biases representations of gender across development.

From early in development, race biases how children think about gender-often in a manner that treats Black women as less typical and representative of women in general than White or Asian women. The present study (N = 89, ages 7-11; predominately Hispanic, White, and multi-racial children) examined the generalizability of this phenomenon across middle childhood and the mechanisms underlying variability in its development. Replicating prior work, children were slower and less accurate to categorize the gender of Black women compared to Asian or White women, as well as compared to Black men, suggesting that children perceived Black women as less representative of their gender.

Beliefs about social norms and racial inequalities predict variation in the early development of racial bias.

Racism remains a pervasive force around the world with widespread and well documented harmful consequences for members of marginalized racial groups. The psychological biases that maintain structural and interpersonal racism begin to emerge in early childhood, but with considerable individual variation-some children develop more racial bias than others. The present study (N = 116; 4-year-old children) provides novel insights into the developmental mechanisms underlying the emergence of racial bias by longitudinally documenting how two psychological processes-normative beliefs about interracial friendships and explanatory beliefs about racial inequalities-developmentally predict the emergence of pro-White/anti-Black racial bias during early childhood.

Categories convey prescriptive information across domains and development.

Young children display a pervasive bias to assume that what they observe in the world reflects how things are supposed to be. The current studies examined the nature of this bias by testing whether it reflects a particular form of reasoning about human social behaviors or a more general feature of category representations. Children aged 4 to 9 years and adults (N = 747) evaluated instances of nonconformity among members of novel biological and human social kinds.

Why do children show racial biases in their resource allocation decisions?

Young children often prefer people high in status and with access to resources. Children also favor fairness and equality, especially when it comes to sharing. Two studies examined how children (N = 185; age range = 4.

Does It Matter How We Speak About Social Kinds? A Large, Preregistered, Online Experimental Study of How Language Shapes the Development of Essentialist Beliefs.

A problematic way to think about social categories is to essentialize them-to treat particular differences between people as marking fundamentally distinct social kinds. From where do these beliefs arise? Language that expresses generic claims about categories elicits some aspects of essentialism, but the scope of these effects remains unclear. This study (N = 204, ages 4.

The Unintended Consequences of the Things We Say: What Generic Statements Communicate to Children About Unmentioned Categories.

Adults frequently use generic language (e.g., "Boys play sports") to communicate information about social groups to children.

The Development of Social Categorization.

Social categorization is a universal mechanism for making sense of a vast social world with roots in perceptual, conceptual, and social systems. These systems emerge strikingly early in life and undergo important developmental changes across childhood. The development of social categorization entails identifying which ways of classifying people are culturally meaningful, how these categories might be used to predict, explain, and evaluate the behavior of other people, and how one's own identity relates to these systems of categorization and representation.

Advancing Developmental Science via Unmoderated Remote Research with Children.

This article introduces an accessible approach to implementing unmoderated remote research in developmental science-research in which children and families participate in studies remotely and independently, without directly interacting with researchers. Unmoderated remote research has the potential to strengthen developmental science by: (1) facilitating the implementation of studies that are easily replicable, (2) allowing for new approaches to longitudinal studies and studies of parent-child interaction, and (3) including families from more diverse backgrounds and children growing up in more diverse environments in research. We describe an approach we have used to design and implement unmoderated remote research that is accessible to researchers with limited programming expertise, and we describe the resources we have made available on a new website (discoveriesonline.
