The Development of Social Essentialism
As early as four years of age, children begin to believe that people who share membership in an ethnic or gender group are similar to each other, and different from members of other groups, in many non-obvious and fundamental ways. For instance, children think that if one girl dislikes math, other girls (but not boys) will dislike it too, or that if one member of an ethic group commits a crime, other members of the group may do so as well. This type of thinking is known as essentialism. Essentialist beliefs about social groups represent the core of stereotyping and prejudice.
The objective of this research project is to examine how essentialist beliefs develop in young children and how we might be able to prevent their formation. In particular, these studies examine the role of language that describes abstract categories (e.g., girls play with dolls)in the cultural transmission of essentialist beliefs. These studies test the hypotheses that parents produce this type of language when talking about groups for which they hold essentialist beliefs, and that hearing this type of language leads children to develop essentialist beliefs about those groups as well. In this way, parents may unknowingly transmit essentialist beliefs to their children.
If these hypotheses are supported, this research will yield concrete implications for how to reduce prejudice by reducing children's exposure to certain forms of language. For example, educating parents on the consequences of using language that describes abstract categories, and encouraging them to reduce the use of such sentences, could lead to a reduction in the next generation's tendencies towards prejudice. Grounding these changes in mechanisms that have been empirically shown to influence the formation of essentialist beliefs could lead to more effective efforts to reduce societal prejudice.

The Role of Within-Category Variability in the Development of Induction
From early in development, children use categories to learn about the world around them. For example, upon learning something about an individual (e.g., that a spider bites), children can generalize this information to the category as a whole (e.g., all spiders), and use this information to guide behavior (e.g., to avoid spiders). A critical--and often useful--assumption that underlies this form of reasoning is the belief that members of a category are highly similar to each other. Yet, this assumption can also lead children astray. For example, if children assume that all dogs are friendly because their own cocker spaniel is friendly, they may engage in dangerous behavior if they encounter a vicious dog. Effective induction thus must balance the belief that category members are similar to each other with the recognition that categories also include important variability. These studies examine how the balance between these beliefs contributes to developmental changes in learning across childhood. These studies test the hypotheses that (a) younger children (preschool-age) tend to overlook within-category variability, leading them to over-generalize new information, (b) children recognize more within-category variability as they get older, leading to more efficient inductive learning, and (c) guiding younger children to recognize the importance of within-category variability helps them to learn more efficiently.
This research aims to uncover the cognitive developmental processes that lead children to generalize information more or less effectively. In doing so, this research has three immediate implications for education. First, these studies aim to identify a strategy--instruction on within-category variation--that can lead children to generalize information more accurately and efficiently, which could be implemented in a range of educational contexts. Second, these studies illustrate the developmental factors that contribute to children's understanding of a key component of the scientific method--that it is important to obtain converging evidence from diverse sources before drawing a broad conclusion--and thus have implications for how to teach about the scientific method effectively. Third, because reasoning about variability is central to a conceptual understanding of evolution, this work will examine an important developmental factor that should be addressed in the design of science curricula. These studies speak to the key theoretical question of how the mechanisms by which humans acquire new knowledge change across development, and thus have broad theoretical significance for cognitive and developmental psychology. This research also supports extensive training opportunities for students and educational opportunities for families and educators.

?the Linguistic Transmission of Maladaptive Beliefs?
? DESCRIPTION (provided by applicant): This project will develop new strategies for addressing the persistent gender gap in science achievement by targeting the mechanisms by which maladaptive beliefs that interfere with achievement arise. The persistent underrepresentation of women in science limits women's cognitive and economic attainment and-due to the growing number of households relying on the sole income of a female earner-contributes to child poverty and its concomitant negative effects on child physical, emotional, and cognitive development. Increasing the representation of women in science is a crucial way to help girls and women optimize their opportunities for cognitive development, and will also help to close the gender-linked earning gap, decrease rates of child poverty, and improve child health. Maladaptive beliefs-that scientists are a distinct kind of person, that being a scientist requires innate talent, and that scientists are deeply different from non-scientists-reflect an essentialist conception of science that interferes with female students' achievement. This project aims to discover: (a) what experiences cause girls to develop these beliefs, (b) what is responsible for girls having those experiences in the first place, and (c) how to intervene to stop the processes by which these maladaptive beliefs arise. This projects tests the hypothesis that these maladaptive beliefs are transmitted via pervasive but subtle linguistic cues-for example, by asking children to be scientists instead of to do science. These linguistic cues implicitly describe success in science as involving membership in a particular category, thus eliciting maladaptive essentialist beliefs. The planned studies test (a) whether hearing these linguistic cues causes girls to develop maladaptive, essentialist beliefs about science, (b) whether adults' own beliefs cause them to produce these linguistic cues, and (c) whether targeting adults' beliefs and language can help children develop more adaptive beliefs and increase girls' engagement in science. By partnering with a major cultural institution that provides informal educational opportunities to children and by involving educators directly in this work, this projec maximizes the opportunities for this research to lead to rapid changes in educational practices that will benefit children.

Developmental Changes in Reasoning About Biological Kinds
This project will develop new strategies to facilitate efficient scientific reasoning in young children. From early in development, children use categories to learn about the world around them. For example, upon learning something about an individual animal, children can generalize this information to the category as a whole and use it to guide behavior. In this way, if a child learns that a particular spider will bite, the child might infer that all spiders bite, and use that information to avoid spiders in the future. A critical challenge of this type of reasoning is determining whether a limited sample of evidence--for example, a specific spider observed on a particular day--provides information likely to be true of other category members as well. Young children often evaluate samples of evidence much less efficiently than older children or adults, which can impede their biological, social, and scientific reasoning. This project will enhance basic understanding of how and why inductive learning changes across childhood. Through a series of experiments, it will reveal the cognitive and developmental mechanisms that underlie the age-related changes in children's reasoning strategies that have been documented in previous studies. This project will then use this knowledge to devise and test new strategies for facilitating efficient reasoning in children. By developing new educational strategies, partnering with a major informal educational institution, and providing training opportunities for undergraduate and graduate students, this project maximizes opportunities for this research to influence educational practices and benefit educators, children, and future researchers.
The present studies test the hypothesis that younger children seek out samples of evidence that they think best exemplify what members of a category should be like, whereas older children and adults seek out samples that cover the broad variation that exists within categories. For example, young children might think that birds should be relatively small and fly, so when they are seeking information about birds in general, they might choose to consider primarily birds with these traits, such as robins and bluebirds. In contrast, older children might seek out more diverse samples, containing birds such as robins and penguins. To test this hypothesis experimentally, children will be presented with samples of animals and asked to choose which are most informative for learning about the category as a whole. To chart the trajectory of developmental change in children's strategies, the first set of studies will examine whether 5- to 10-year-olds select samples that maximize values on key properties (e.g., choosing to examine the two fastest cheetahs in the world to learn about cheetahs) or diversity (e.g., choosing to examine some fast and some slow cheetahs). The second set of experiments will test two possible accounts of the developmental and cognitive mechanisms underlying observed age-related changes. The third set of studies will develop and test new strategies for facilitating efficient biological and scientific reasoning in educational contexts. Thus, in addition to addressing key theoretical questions in cognitive and developmental psychology, this project will also have immediate implications for education.

Let's Do Science! Promoting the Development of Beneficial Beliefs About Science in Early Childhood
The roots of gender, racial, and ethnic disparities in science achievement take hold in early childhood, with lifelong implications for educational outcomes. Often, these early roots are in the form of problematic beliefs, including beliefs that science is something in which only a select group of people can succeed. These beliefs are particularly discouraging for children from social groups that are underrepresented in science, including girls and children from certain racial and ethnic minority groups. This project will reveal how these problematic beliefs develop and how to promote more beneficial ones?in particular, how to promote beliefs that science is something that people learn to do rather than an identity that one needs to have. Further, this project will test whether targeting these beliefs in early childhood creates positive trajectories of science engagement over children?s transition from prekindergarten into formal schooling. In doing so, this project will develop a new approach to spreading beneficial beliefs about science and promoting science engagement among young children from social groups that are underrepresented in science, while addressing fundamental questions about how beliefs develop and spread across communities. By partnering with teachers to implement this project and using an innovative, webcam-based lab for remote developmental research, this project will maximize the opportunities for this research to lead to rapid changes in educational practices that will broaden participation in science in early childhood. This project is funded by the EHR Core Research program, which emphasizes STEM education research that will generate foundational knowledge in the field.
Phase 1 will reveal the mechanisms by which problematic or beneficial beliefs about science arise in early childhood via an experimental field study with 2,000 children and 200 teachers in a large, public prekindergarten program. This field experiment will test a model of conceptual development and belief transmission wherein children?s beliefs are shaped by subtle features of the language they hear about science; in particular, teachers? use of linguistic cues implying that scientists are a special kind of person, including category labels (e.g., ?Let?s be scientists!?) and generic descriptions of what scientists do or are like (e.g., ?Scientists discover things about the world?). The field experiment will test the influence of reducing these identity-focused linguistic cues, and instead encourage more action-oriented language (e.g., ?Let?s do science! Doing science leads to discovering things about the world?) on the development of children?s science beliefs and behavior. Phase 2 will examine the extent to which children?s developing beliefs about whether success in science requires a special identity have consequences for the development of social stereotypes about science and for children?s science engagement and efficacy over the transition to kindergarten (as social disparities in science interest and social stereotypes about scientists begin to emerge). This phase will entail a two-year longitudinal follow-up study of a subset of 500 children from the field experiment, which will be conducted via an innovative webcam-based lab for remote developmental research, which will allow for longitudinal tracking after children transition schools. Thus, this project will advance research by addressing fundamental questions about the nature of early conceptual and social development, including how language shapes the development of children?s science beliefs and behavior, how children?s beliefs change over time, and how researchers and educators can harness developmental mechanisms to promote positive developmental trajectories of science engagement across diverse populations of children. Creation of a public website to share project materials and findings will enable rapid dissemination to researchers across disciplines, curriculum developers, prekindergarten teachers, and families of young children.

Sbp: Developmental Mechanisms Underlying the Emergence of Racial Bias
This project will provide new insights into how racial biases emerge and develop in early childhood. Racism remains a pervasive force with widespread and well-documented harmful consequences. An important step towards redressing these problems is understanding the psychological processes that maintain and reinforce them. Young children begin to develop harmful and problematic beliefs about race in early childhood (often by 3 years of age), and a majority of children and adolescents of color report experiencing racially-based discrimination. Yet, some children develop stronger racial biases than others, suggesting that the persistence of racial bias is not inevitable. This project will reveal how racial biases emerge and develop in children living across the United States and will examine how parent-child conversations might lead children to form harmful beliefs about race (or serve to prevent them). In doing so, this project will address fundamental questions about how racial biases take root in early childhood and will identify ways that parents can prevent this development. By partnering with several community organizations to implement this project and using an innovative, webcam-based lab for remote developmental research, this project will maximize the opportunities for this research to lead to rapid changes in parenting practices with the potential to reduce the emergence of racial bias in early childhood.
The first part of this project will explore the foundational beliefs that predict the emergence and development of racial bias in children across the United States via a longitudinal study with 300 children and parents who will participate in this research from home using an online lab. This project will examine how children?s emerging beliefs about interracial friendships and racial inequalities predict the future development of racial biases. Specifically, every six months over a three year period, children will complete a series of assessments that gauge their racial biases (e.g., how much they like and want to play with Black and White children), their beliefs about interracial friendships (who their parents would want them to play with, who their friends would want to play with), and whether they believe that racial inequalities are due to essentialist (e.g., inherent/intrinsic differences between racial groups) or structural (e.g., differential access to resources and opportunities) factors. This study will test the hypotheses that children who hold more exclusive beliefs about interracial friendships and more essentialist beliefs about racial inequalities will develop higher levels of racial biases. The second part of this project will explore an important developmental mechanism by which children develop problematic beliefs about interracial friendships and racial inequalities: parent-child conversations. Using our online lab, 105 children and parents will complete a series of role-playing activities designed to spur conversations about racial inequalities; conversations will be coded for subtle linguistic cues that imply that racial and socioeconomic groups reflect inherently different types of people, as well as for essentialist and structural explanations for racial disparities. These features of parent-child conversations will then be used to predict children?s racial biases and foundational beliefs as in Part A. Thus, this project will advance our understanding of how racial biases emerge and develop in early childhood. By identifying the core features of parent-child conversations that can foster or impede these beliefs, this project will also inform future interventions aimed at reducing the development of racial bias. By disseminating the results of this research via our online lab, we will enable easy access to our findings for researchers, parents, educators, and policy makers.
