Correlational studies link spatial‐test scores and science, technology, engineering, and mathematics achievement. Here we asked whether children's understanding of astronomical phenomena would benefit from a prior intervention targeting a core component of children's projective spatial concepts—understanding that viewers' visual experiences are affected by vantage point. Children (8–9 years; N = 66) received outdoor and indoor experiences that did (Experimental) or did not (Control) focus on how scene appearance is affected by viewers' positions and movements. All then received an astronomy lesson about celestial motions (e.g., Sun apparent motion). Experimental‐group children scored higher on immediate and 1‐week perspective‐taking tests and explained celestial phenomena more accurately than did control‐group children. Data demonstrate that general spatial training—divorced from specific science content—can aid children's subsequent learning of scientific phenomena. [ABSTRACT FROM AUTHOR]

Many children feel obligated by their parents and peers to behave in ways that are consistent with traditional gender roles of their culture, an obligation referred to as “felt pressure to conform to gender roles” (abbreviated as felt pressure) (Egan and Perry 2001). The current research was designed to examine links between children’s felt pressure and (a) their own responses to other peers’ “gender policing” and (b) their parents’ reports of gender socialization attitudes. U.S. children (6–12-years-old; 37 girls; 40 boys) completed self-report measures assessing (a) felt pressure to conform to gender roles and (b) responses to children described as making sexist remarks to peers (12 vignettes). Parents (66 mothers; 7 fathers) completed a gender-socialization measure of attitudes toward their children’s gender-typical and atypical behaviors. As hypothesized, children who reported more felt pressure were less likely to confront—and more likely to agree with—vignette peers’ sexist comments to another child. Specifically, felt pressure from parents was negatively related to children’s confrontation of vignette peers’ sexist comments, and felt pressure from peers was positively related to children’s agreement with vignette peers’ sexist comments. Children’s felt pressure was unrelated to parents’ self-reported attitudes. Findings suggest that felt pressure experiences with parents and peers are differentially related to children’s peer interactions, suggesting a possible mechanism by which levels of sexism may be shaped in peer groups. Results may inform interventions aimed at gender-related bullying, identifying the groups (i.e., parents or peers) most influential for various bullying behaviors and bystander responses.

Morality and gender are intersecting realms of human thought and behavior. Reasoning and action at their intersection (e.g., views of women’s rights legislation) carry important consequences for societies, communities, and individual lives. In this chapter, the authors argue that children’s developing views of morality and gender reciprocally shape one another in important and underexplored ways. The chapter begins with a brief history of psychological theory and research at the intersection of morality and gender and suggests reasons for the historical failure to view gender attitudes through moral lenses. The authors then describe reasons for expecting morality to play an important role in shaping children’s developing gender attitudes and, reciprocally, for gender attitudes to play an important role in shaping children’s developing moral values. The authors next illustrate the importance and relevance of these ideas by discussing two topics at the center of contentious debate in the United States concerning ethical policy and practice: treatment of gender nonconformity and gender-segregated schooling. The chapter concludes with suggestions for future research.

To study effects of the gender-packaging of science, technology, engineering, and mathematics (STEM) toys, mother-child dyads (31 daughters; 30 sons; M = 5.2 years) were randomly assigned to play with a mechanical toy packaged for girls (GoldieBlox) or boys (BobbyBlox). When familiarizing themselves with the toy to prepare for play, mothers given BobbyBlox built more with toy pieces than did mothers given GoldieBlox. During dyadic play, mothers with sons built more; mothers with daughters read the toy's narrative instructions more. Children's independent play likewise varied with game packaging. Girls learned the mechanical belt-drive principle better from playing with BobbyBlox; boys learned the principle better from playing with GoldieBlox. Implications for gender-schema theories, STEM interventions, and toy marketing are discussed.

Parents’ distancing language—language that requires cognitive abstraction and moves beyond the “here and now”—relates to children’s literacy skills, but its association with mathematics remains unexamined. Participants were 242 mother–child dyads from African American, Chinese American, Dominican American, and Mexican American backgrounds. Mothers’ distancing language was examined while mothers shared a wordless book with their 5-year-olds; children’s math and literacy skills were assessed when children were 5.0 and 6.5 years of age. Mothers’ distancing language, but not amount of language (word tokens), related to children’s concurrent math and literacy skills. Mothers’ distancing language predicted growth in children’s literacy skills over time and related to later math indirectly through associations with early math. The importance of distancing language for cognitive growth may have implications for parenting and classroom practice.

College students' beliefs concerning socializing children about sexism and other culturally important topics were investigated using mixed methods. In Study 1, participants (N = 71) defined sexism and explained their beliefs about addressing sexism with children. Thirty-five percent argued against childhood sexism-socialization. Emergent themes provided insights about how sexism is viewed and yielded data needed to design a closed-ended socialization-beliefs survey. In Study 2, students (N = 141) completed this survey and reported their feminist beliefs and childhood-socialization experiences. Childhood sexism-socialization was more commonly endorsed by women, stronger feminists, and those who had themselves experienced childhood sexism-socialization. Descriptive data document socialization beliefs about 21 culturally important topics. Results suggest that programs aimed at socializing children about sexism should also address beliefs of the adults responsible for program implementation.

This study investigates the role of perspective-taking skills in how children explain spatially complex astronomical phenomena. Explaining many astronomical phenomena, especially those studied in elementary and middle school, requires shifting between an Earth-based description of the phenomena and a space-based reference frame. We studied 7- to 9-year-old children (N = 15) to (a) develop a method for capturing how children make connections between reference frames and to (b) explore connections between perspective-taking skill and the nature of children's explanations. Children's explanations for the apparent motion of the Sun and stars and for seasonal changes in constellations were coded for accuracy of explanation, connection between frames of reference, and use of gesture. Children with higher spatial perspective-taking skills made more explicit connections between reference frames and used certain gesture-types more frequently, although this pattern was evident for only some phenomena. Findi...

Gender schema theory (GST) posits that children approach opportunities perceived as gender appropriate, avoiding those deemed gender inappropriate, in turn affecting gender-differentiated career trajectories. To test the hypothesis that children's gender salience filters (GSF-tendency to attend to gender) moderate these processes, 62 preschool girls (M = 4.5 years) were given GSF measures. Two weeks later, they played a computer game about occupations that manipulated the game-character's femininity (hyperfeminized Barbie vs. less feminized Playmobil Jane). Following game play, girls' interests in feminine activities showed an interaction of game condition and GSF: High-GSF girls showed intensified feminine activity interests only with Barbie; low-GSF girls showed no change with either character. Neither GSF nor game condition affected occupational interests. Implications for GST, individual differences, and occupational interventions are discussed.

Sandra Bem has profoundly affected the ways that gender, gender roles, and gender development have been conceptualized and investigated by generations of scholars. Her legacy also offers an inspiring model of how academic scholarship can promote gender-egalitarian policy and practice. In our review, we identify four ways that Bem’s work has shaped gender-development scholarship in general, and our individual and collaborative programs of research in particular. The empirical research and policy we discuss are drawn primarily from the United States, the context in which Bem worked and lived. We begin by describing Bem’s analysis and critique of the societal practices that establish gender as a highly salient social category in the first place. We then outline her contributions to gender-schema approaches, including her conceptual work on gender-schema theories and her empirical work on the effects of gender schematicity on memory and self-socialization. Next we review the parenting strategies Bem suggested and enacted as she attempted to raise gender aschematic, egalitarian children. In the closing section we reflect on Bem’s lifelong commitment to connecting the spheres of social science research, personal life, and public policy. In addition to highlighting ways in which her work has already proven to be inspirational for our own and others’ scholarship and action, we point to ways that it offers rich ideas for future research and action that may clarify gender-developmental processes and may further reduce the constraining effects of societal gender dichotomies on new generations of children.

Around the globe, educational opportunities and outcomes have long varied in relation to student gender. Within the United States, a particularly intense and growing controversy concerns whether education should be delivered in single-sex contexts. This paper offers a broad framework for approaching this controversy. I review arguments made by historical and contemporary proponents of gender-differentiated education, concluding that these reveal a foundational commitment to gender essentialism (rather than to gender constructivism more commonly embraced by critics of single-sex schooling). I suggest that different gender conceptualizations and different professional traditions affect the kind of data one collects, weighs, and reports. Gender conceptualizations also affect the valence assigned to the amplification or attenuation of gender differences in educational, career, or personal student outcomes. I then propose that other kinds of human values are also relevant to the controversy. Given that in justifying their position, advocates of single-sex public education have recently been focusing less on gendered brain differences and more on the expansion of educational choice, I focus especially on the value of choice. Using arguments paralleling those found in critiques of the U.S. charter-school movement, I suggest that decisions about school choice necessarily entail judgments about a range of goals and human priorities. I close by suggesting that a resolution of the controversy about single-sex education cannot be reached through empirical data alone, but will require discussions of gender conceptualizations, what constitutes evidence, ideal educational outcomes, and broader human values.

Each individual’s personal experiences—and the developmental environments that individuals create for others’ personal experiences—are profoundly affected by membership in, and attitudes toward, social groups. Although social groups may offer supports to their members and though members may contribute to groups’ collective good, social-group divisions also create occasions for stereotyping and prejudice. This article reviews developmental intergroup theory (Bigler & Liben, 2006) that argues for the emergence of stereotyping and prejudice through the relational interplay of constructive and contextual processes. The theory is then discussed in the domain of gender by describing first, illustrative laboratory and field research on gender stereotypes and biases, and second, implications for gender-segregated (single-sex) educational programs.

As part of their book on children's developing conceptions of space, Piaget and Inhelder (1948/1956) described age-related performance on their water level task (WLT). The WLT was intended to assess respondents' ability to perceive and represent a horizontal (water) line within a surrounding non-orthogonal frame (a tilted container's straight sides). They reported age-linked increments in performance, implying that cognitively intact individuals would uniformly master the task by middle childhood. Described here are studies demonstrating that even many adults, especially women, find the task challenging. Also discussed is research demonstrating links between performance on paper-and-pencil lab measures like the WLT and performance on ecological tasks such as skill in using cartographic maps in large outdoor environments or in learning a new geological concept. The description offers a case history to illustrate the interplay between laboratory and ecological research.

Quinn and Liben (2008) reported a sex difference on a mental rotation task in which 3- to 4-month-olds were familiarized with a shape in different rotations and then tested with a novel rotation of the familiar shape and its mirror image. As a group, males but not females showed a significant preference for the mirror image, a pattern paralleled at the individual level (with most males but less than half the females showing the preference). Experiment 1 examined a possible explanation for this performance difference, namely, that females were more sensitive to the angular differences in the familiarized shape. Three- to 4-month-olds were given a discrimination task involving familiarization with a shape at a given rotation and preference testing with the shape in the familiarized versus a novel rotation. Females and males preferred the novel rotation, with no sex difference observed. This finding did not provide support for the suggestion that the sex difference in mental rotation is explained by differential sensitivity to angular rotation. Experiment 2 revealed that the sex difference in mental rotation is observed in 6- to 7-month-olds and 9- to 10-month-olds, suggesting that a sex difference in mental rotation is present at multiple ages during infancy.

Researchers have shown that young children solve mapping tasks in small spaces, but have rarely tested children's performance in large, unfamiliar environments. In the current research, children (9-10 years; N = 40) explored an unfamiliar campus and marked flags' locations on a map. As hypothesized, better performance was predicted by higher spatial-test scores, greater spontaneous use of map-space coordinating strategies, and participant sex (favoring boys). Data supported some but not all hypotheses about the roles of specific spatial skills for mapping performance. Data patterns were similar on a computer mapping task that displayed environmental-scale videos of walks through a park. Patterns of children's mapping errors suggested both idiosyncratic and common mapping strategies that should be addressed in future research and educational interventions.

Gender has long been, and continues to be, a powerful predictor of developmental experiences and outcomes. Observations drawn from personal history, developmental science, and life beyond the academy show that historically, gender constraints have diminished in some ways, but remain robust in others. Reviewed are children's constructive processes that--in interaction with the embedding ecology--foster the emergence and persistence of gendered phenomena. Reviews of interventions designed to increase girls' science participation demonstrate the need to evaluate both intended and unintended program consequences. Discussion of the single-sex schooling debate shows the importance of foundational conceptualizations of gender, and illuminates research-to-policy processes. After identifying newly emerging gender conceptualizations, the concluding section highlights the need to consider how gender conceptualizations do and should affect science and society.

Children gradually develop interpretive theory of mind (iToM)—the understanding that different people may interpret identical events or stimuli differently. The present study tested whether more advanced iToM underlies children’s recognition that map symbols’ meanings must be communicated to others when symbols are iconic (resemble their referents). Children (6–9 years; N = 80) made maps using either iconic or abstract symbols. After accounting for age, intelligence, vocabulary, and memory, iToM predicted children’s success in communicating symbols’ meaning to a naive map-user when mapping tasks involved iconic (but not abstract) symbols. Findings suggest children’s growing appreciation of alternative representations and of the intentional assignment of meaning, and support the contention that ToM progresses beyond mastery of false belief.

A foundational skill for all field-based sciences is the ability to accurately record the location of field observations onto a map. To investigate the strategies children use when recording their observations during field-based inquiries, fourth graders were asked to indicate the location of colored flags by placing similarly colored stickers on a map and, after each placement, to write down what clues they used to decide where to place each sticker. This flag–sticker task simulates the way field scientists use maps, as, for example, when ecologists record animal sightings. Participants used a rich vocabulary of spatial descriptors, drawing on topological and projective spatial concepts. No one reported using the available graphic scale or directional arrow. For inaccurately placed stickers, the accompanying verbal reports suggest that, most commonly, students attended to irrelevant or insufficient information in the environment. The hypothesized interpretation is that students have not fully mastered th...

Developmental intergroup theory posits that when environments make social-group membership salient, children will be particularly likely to apply categorization processes to social groups, thereby increasing stereotypes and prejudices. To test the predicted impact of environmental gender salience, 3- to 5-year-old children (N = 57) completed gender attitude, intergroup bias, and personal preference measures at the beginning and end of a 2-week period during which teachers either did or did not make gender salient. Observations of peer play were also made at both times. After 2 weeks, children in the high- (but not low-) salience condition showed significantly increased gender stereotypes, less positive ratings of other-sex peers, and decreased play with other-sex peers. Children's own activity and occupational preferences, however, remained unaffected.

Work fulfills personal values, perhaps differently for males and females. Explored here was the role values play in shaping occupational interests. Study 1 examined children's, adolescents', and adults' (N = 313) occupational values (regarding money, power, family, altruism), occupational interests, and perceptions of values afforded by traditionally masculine and feminine occupations. Results revealed sex differences in occupational values and interests. Furthermore, participants' values predicted their own interests in culturally masculine and feminine occupations. Study 2 used novel jobs and experimentally manipulated prototypical sex of worker and value affordances to disentangle their effects on occupational interests. At all ages, participants' (N = 240) occupational interests were affected by the depicted sex of the workers and by the stated value affordances of the jobs.

Children and even some adults struggle to understand and use maps. In the symbolic realm, users must appreciate that the marks on a surface stand for environments and must understand how to interpret individual symbols. In the spatial realm, users must understand how representational space is used to depict environmental space. To do so, they must understand the consequences of cartographic decisions about the map's viewing distance, viewing angle, viewing azimuth, and geometric projection. Research identifies age-linked progressions in symbolic and spatial map understanding that are linked to normative representational and spatial development, and reveals striking individual differences. Current work focuses on identifying experiences associated with better map understanding. New technologies for acquiring, manipulating, analyzing, and displaying geo-referenced data challenge users and researchers alike.

Elementary-school children (81 boys, 72 girls, aged 5–10 years) in the Southwest United States were taught to challenge peers’ sexist remarks to (a) improve school climate for gender nontraditional children, (b) decrease children’s gender-typed attitudes, and (c) test hypotheses linking gender identity and peer-directed gender role behaviors. Children either practiced using retorts to peers’ sexist remarks (practice condition) or heard stories about others’ retorts (narrative condition). At pretest, children rarely challenged peers’ sexist remarks. At posttest, children’s challenges were significantly more common in the practice than narrative condition. At the 6-month posttest, data showed intervention effects had become more widespread. Behavioral changes led to decreases in gender-typing of others among girls but not boys.

Geologists and undergraduate students observed eight artificial “rock outcrops” in a realistically scaled field area, and then tried to envision a geological structure that might plausibly be formed by the layered rocks in the set of outcrops. Students were videotaped as they selected which of fourteen 3‐D models they thought best represented the geological structure and then explained their choice. The focus of this paper is on how students reasoned from observations to inferences. Students used observations of outcrops’ location, steepness (dip), orientation (strike), stratigraphy, and placement relative to topography to infer whether the structure was convex or concave, deep or shallow, symmetrical or asymmetrical, open or closed, and elongate or circular. On average, science majors produced more than twice as many evidence‐supported claims than did non‐science majors. Science majors produced more valid lines of reasoning than did non‐science majors, and students who selected a correct model produced m...

The contribution of intentionality understanding to symbolic development was examined. Actors added colored dots to a map, displaying either symbolic or aesthetic intentions. In Study 1, most children (5-6 years) understood actors' intentions, but when asked which graphic would help find hidden objects, most selected the incorrect (aesthetic) one whose dot color matched referent color. On a similar task in Study 2, 5- and 6-year-olds systematically picked incorrectly, 9- and 10-year-olds picked correctly, and 7- and 8-year-olds showed mixed performance. When referent color matched neither symbolic nor aesthetic dot colors, children performed better overall, but only the oldest children universally selected the correct graphic and justified choices with intentionality. Results bear on theory of mind, symbolic understanding, and map understanding.

SUMMARY The authors review their Developmental Pathway Models that characterize normative gender differentiation during childhood. Particular attention is paid to the attitudinal pathway model that describes the routes by which children's gender attitudes guide the selection and impact of gender-related experiences for the self. The personal pathway model describes the ways in which children's own interests and skills may affect their gender-related attitudes about others. The authors identify opportunities for the emergence of various kinds of gender nonconformity in relation to the constructs and mechanisms in these models.

Social stereotyping and prejudice are intriguing phenomena from the standpoint of theory and, in addition, constitute pressing societal problems. Because stereotyping and prejudice emerge in early childhood, developmental research on causal mechanisms is critical for understanding and controlling stereotyping and prejudice. Such work forms the basis of a new theoretical model, developmental intergroup theory (DIT), which addresses the causal ingredients of stereotyping and prejudice. The work suggests that biases may be largely under environmental control and thus might be shaped via educational, social, and legal policies.
