The development of gender differentiation in young children

Children cooperate more with in-group members than with out-group members in an iterated face-to-face Prisoner's Dilemma Game

Adults are more likely to cooperate with in-group members than with out-group members in the context of social dilemmas, situations in which self-interest is in conflict with collective interest. This bias has the potential to profoundly shape human cooperation, and therefore it is important to understand when it emerges in development. Here we asked whether 6- to 9-year-old children (N = 146) preferentially cooperate with in-group members in the context of a well-studied social dilemma, the iterated Prisoner's Dilemma Game. We assigned children to minimal groups and paired them with unfamiliar same-age and same-gender peers. Consistent with our predictions, children were more likely to cooperate with in-group members than with out-group members in this minimal group context. This finding adds to the current literature on group bias in children's prosocial behavior by showing that it affects decision making in a context that calls on strategic cooperation. In addition, our analyses revealed an effect of gender, with girls more likely to cooperate than boys regardless of the group membership of their partner. Exploring this gender effect further, we found an interaction between gender and age across condition, with older girls showing less sensitivity to the group membership of their partner than younger girls and with older boys showing more sensitivity to the group membership of the partner than younger boys. Our findings suggest that risky cooperation in the face of social dilemmas is shaped by group bias during childhood, highlighting the potentially deeply rooted ties between cooperation and parochialism in humans.

Girls Are Better Students but Boys Will Be More Successful at Work: Discordance Between Academic and Career Gender Stereotypes in Middle Childhood

Despite findings of female advantages at school, men still are higher achieving in the workplace. Only a small amount of research has simultaneously investigated stereotypes of these different domains. We investigated whether stereotypes about academic female superiority and paradoxical stereotypes about workplace male superiority coexist. Participants were 1144 Grades 1-6 students (M_age = 9.66) from Hong Kong. They completed measures of academic gender stereotypes and meta-stereotypes, career gender stereotypes, career-related motivation for school excellence, and school engagement. Teachers provided school exam scores. We examined (1) gender and age differences, (2) the relationship between the stereotypes, and (3) the moderating role of these stereotypes in gender differences in school engagement, exam scores, and career-related motivation. Both boys and girls perceived girls as better students but a belief in female superiority did not translate to the career domain. Although both boys and girls beginning primary school believed their gender was superior in both domains, those at the end of primary school believed that girls do better at school while men are more successful at work. Also, at the end of primary school, these two stereotypes were more discordant on the individual level, i.e., the tendency for children who believed that girls perform better at school to also believe that women perform better at work was weaker in older children. Academic gender stereotypes moderated gender differences in school engagement and exam scores. Understanding why children hold discordant beliefs about success in different arenas and combating both academic and career stereotypes early may help improve gender equality for both genders.

Diversity vs. ingroup: How children generalize for the common good

How do children generalize for the common good? The present study investigated whether children are more likely to use the preference of their ingroup (ingroup rationale) or that of a diverse group (diversity rationale) as a basis for generalization about the broader community. In a series of studies, five-year-olds from two different cultures (US and China), yet living in environments with analogous ingroup majority-outgroup minority structure, were asked to generalize either the preference of a diverse sample or the preference of an ingroup sample to the majority. We found that children from both cultures have a default strategy to generalize from their ingroup (Study 1). However, Studies 2-4 show that this ingroup default is amenable to change, suggesting that children mostly use this strategy because ingroup members were salient and conveniently available. When ingroup was removed or reduced (Study 2), or when primed with photos of diverse populations (Studies 3 & 4), children changed their strategies and were more likely to use the diversity-rationale. In both cultures, the intergroup structure of children's living environment exerts similar pressures, resulting in analogous outcomes in generalizing for the common good.

Which group matters more: The relative strength of minimal vs. gender and race group memberships in children's intergroup thinking

Experimentally created "minimal" social groups are frequently used as a means to investigate core components of intergroup cognition in children and adults. Yet, it is unclear how the effects of such arbitrary group memberships compare to those of salient real-world group memberships (gender and race) when they are directly pitted against each other in the same studies. Across three studies, we investigate these comparisons in 4-7-year-olds. Study 1 (N = 48) establishes the minimal group paradigm, finding that children develop ingroup preferences as well as other forms of group-based reasoning (e.g., moral obligations) following random assignment to a minimal group. Study 2 (N = 96) and Study 3 (N = 48) directly compare this minimal group to a real-world social group (gender or race) in a cross-categorization paradigm, in which targets are participants' ingroups in terms of the minimal group and outgroups in terms of a real-world social group, or vice versa. The relative strength of the minimal group varies, but in general it either has a similar effect or a stronger effect as compared to race and in some cases even gender. Our results support the contention that an abstract tendency to divide the world into "us" and "them" is a central force in early intergroup cognition.

The role of expertise and culture in visual art appreciation

Is art appreciation universal? Previous evidence suggests a general preference for representational art over abstract art, and a tendency to like art originating from one’s own culture more than another culture (an ingroup bias), modulated by art expertise. However, claims about universality are difficult given that most research has focused on Western populations. Across two pre-registered and statistically powered experiments, we explore the role of culture and art expertise in the aesthetic evaluation of Indian and Western paintings and dance depicting both abstract and representational content, by inviting expert and art-naïve Indian and Western participants to rate stimuli on beauty and liking. Results suggest an ingroup bias (for dance) and a preference for representational art (for paintings) exists, both modulated by art expertise. As predicted, the ingroup bias was present only in art-naïve participants, and the preference for representational art was lower in art experts, but this modulation was present only in Western participants. The current findings have two main implications: (1) they inform and constrain understanding of universality of aesthetic appreciation, cautioning against generalising models of empirical aesthetics to non-western populations and across art forms, (2) they highlight the importance of art experience as a medium to counter prejudices.

Culture influences the development of children's gender-related peer preferences: Evidence from China and Thailand

Current understanding of how culture relates to the development of children's gender-related peer preferences is limited. To investigate the role of societal acceptance of gender nonconformity, this study compared children from China and Thailand. Unlike China and other cultures where the conceptualization of gender as binary is broadly accepted, individuals who identify as a nonbinary "third" sex/gender have been highly visible and tolerated in Thai society for at least several decades. Chinese and Thai 4- to 9-year-olds (N = 458) viewed vignettes of four hypothetical peers who varied on gender (i.e., boy vs. girl) and gender-typed toy play behavior (i.e., masculine vs. feminine), and were asked to give a friendship preference rating for each peer. Chinese, compared with Thai, children evidenced gender-related peer preferences that emerged earlier, remained more stable across age groups, and were relatively more biased against gender-nonconforming behavior. The only cultural similarity was in children's preference for peers who were of the same gender and/or displayed same-gender-typed behavior. Thus, while preference for peers who are of the same gender and/or display same-gender-typed behavior is common among children across cultures, the developmental onset and course of these preferences vary by culture. Moreover, societal acceptance of gender nonconformity might be key to limiting children's bias against gender-nonconforming peers.

Mothers, fathers and the intergenerational transmission of gender ideology

Traditional gender beliefs play an important role in (re-)producing gender inequalities, and trends towards gender egalitarianism have stalled. As such, identifying factors that contribute to individuals upholding traditional versus egalitarian gender attitudes is an important scholarly endeavour. While previous studies have identified critical predictors-such as religion, education and parenthood-intergenerational influences have received comparatively little empirical attention. Drawing upon gender-socialization theory, we derive hypotheses about how parental attitudes towards gender are transmitted to their children, considering differences between mothers' and fathers' influences, parental (dis)agreement in attitudes, and moderation by child's gender. We test these hypotheses using high-quality data from a national sample of Australian 14/15-year-old adolescents (Longitudinal Study of Australian Children, n = 1806). We find substantial intergenerational associations in gender ideology. Paternal and maternal attitudes exert a similar degree of influence on their children's attitudes, and have complementary rather than cumulative effects. While fathers' attitudes influence sons' and daughters' attitudes equally, mothers' attitudes influence daughters' attitudes more than sons'.

The academic success of boys and girls as an identity issue in gender relations: when the most threatened is not the one expected

The present research aims to determine whether girls' higher academic achievement, which should grant them a higher academic status than boys, could prevent them from experiencing social-identity threat on this dimension. Because they fear situations questioning their superiority, we argue that an unfavorable intergroup comparison would be more threatening for the high-status, rather than low-status, group on the dimension of academic achievement. Two studies were conducted, respectively, in high school, where girls should represent the high-status group (Study 1), and middle school, where students might perceive their own group as the high-status group (Study 2). Although both middle-school and high-school students perceived girls as the high-status group, they appraised the outgroup superiority differently. Indeed, it had more impact on girls' perceived threat and boys' perceived challenge in high school (Study 1), but not in middle school (Study 2). The results, however, did not show significant impact of context on performance.

Comparing race, gender, age, and career categories in recognizing and grouping tasks

The purpose of our research was to compare how participants weighed age, gender, race, and career categories in recognizing and grouping tasks. In Study 1, we used a category recognition task to compare participants' speeds in recognizing information from different categories. The results showed that participants recognized the gender information most quickly, followed by career, race, and age information. In Study 2, a categorization task was used to compare participants' category preferences. The results showed that the career category had the greatest weight, and the gender category had the lowest weight. Two targets who had different career identities were more possible considered as belonging to different groups than two targets with different gender, race or age identities. Our results have implications in understanding the weight of different categories, with gender and career category are the most important category that affects perception and evaluation.

Minimal but meaningful: Probing the limits of randomly assigned social identities

The current studies (total N = 151) experimentally manipulated meaningfulness in novel social groups and measured any resulting ingroup biases. Study 1 showed that even when groups were arbitrary and presumptively meaningless, 5- to 8-year-old children developed equally strong ingroup biases as children in more meaningful groups. Study 2 explored the lengths required to effectively reduce ingroup biases by stressing the arbitrariness of the grouping dimension. Even in this case, ingroup bias persisted in resource allocation behavior, although it was attenuated on preference and similarity measures. These results suggest that one needs to go to great lengths to counteract children's tendency to imbue newly encountered social groups with rich affiliative meaning.

The role of intergroup biases in children's endorsement of information about novel individuals

A great body of evidence suggests that children are remarkably selective in accepting information from different sources. Yet, very few studies have focused on children's learning about the attributes of others. In three experiments, we examined how 6- and 7-year-olds' ingroup and outgroup biases about novel target individuals and their biases to follow ingroup informants interact in social learning contexts. Overall, children exhibited a positivity bias, accepting positive testimony about ingroup and outgroup targets, but this bias was significantly higher for ingroup targets. Furthermore, whereas children accepted the positive testimony about ingroup targets regardless of the informant's group membership, children selectively relied on ingroup informants when endorsing information about outgroup targets. These results suggest that children's existing biases interact with their acquisition of knowledge in complex ways and shape their social evaluations. These findings may have important implications for developing strategies to prevent negative biases against outgroup individuals among children.

Children's evaluation and categorization of transgender children

Despite extant evidence of negative peer treatment of transgender adolescents and adults, little is known about how young children perceive transgender peers, particularly those who have socially-transitioned, or are living in line with their gender, rather than sex at birth. Whereas children have been shown to be averse to gender nonconformity in peers, because many transgender children appear and behave in ways consistent with their expressed gender (but not their sex at birth), it is unclear how children evaluate these identities. In two studies, we investigated 5- to 10-year-old children's (N _total =113) preferences for transgender vs. gender-"typical" peers who either shared their gender identity or did not. We also examined whether children categorize transgender peers by their sex or expressed gender, as this might inform their evaluations. Children preferred cisgender peers over transgender peers; however, they also liked peers of their own gender rather than the other gender (e.g., female participants preferred girls over boys), demonstrating that the oft-documented own-gender bias plays an important role even when children are reasoning about transgender peers. Children did not reliably categorize transgender peers by sex or gender; yet, those who categorized transgender peers by their sex showed greater dislike of transgender peers. The current studies are the first to investigate cisgender children's attitudes toward transgender children, and suggest that perceptions of gender categorization and conformity play a role in children's evaluations of transgender peers.

The Developmental Origins of Dehumanization

Dehumanization is a complex social phenomenon, intimately connected to intergroup harm and neglect. However, developmental research has only recently started to investigate this important topic. In this chapter, we review research in areas closely related to dehumanization including children's intergroup preferences, essentialist conceptions of social groups, and understanding of relative status. We then highlight the small number of recent studies that have investigated the development of this social bias more directly. We close by making a series of suggestions for future research that will enable us to better understand the nature and causes of this harmful phenomenon.

Gender differences in mathematics achievement in Beijing: A meta-analysis

BACKGROUND

The topic of gender differences in mathematical performance has received considerable attention in the fields of education, sociology, economics and psychology.

AIMS

We analysed gender differences based on data from the Beijing Assessment of Educational Quality in China.

SAMPLE

A large data set of Grade 5 and Grade 8 students who took the mathematical test from 2008 to 2013 (n = 73,318) were analysed.

METHOD

Meta-analysis was used in this research.

RESULTS

The findings were as follows. (1) No gender differences in mathematical achievement exist among students in Grade 5, relatively small gender differences exist in Grade 8, females scored higher than males, and variance of male students is larger than that of females in both Grade 5 and Grade 8. (2) Except for statistics and probability, gender differences in other domains in Grade 8 are significantly higher than those in Grade 5, and female students outperform males. (3) The ratio of students of both gender in Grade 5 and Grade 8 at the 95-100% percentile level shows no significant differences. However, the ratio of male students is significantly higher than that of females at the 0-5% percentile level. (4) In Grade 5, the extent to which females outperformed males in low SES group is larger than that in higher SES groups, and in Grade 8, the magnitude of gender differences in urban schools is smaller than that in rural schools.

CONCLUSION

There is a small gender difference among the 8th graders, with the male disadvantage at the bottom of the distribution. And gender differences also vary across school locations.

Early preschool environments and gender: Effects of gender pedagogy in Sweden

To test how early social environments affect children's consideration of gender, 3- to 6-year-old children (N=80) enrolled in gender-neutral or typical preschool programs in the central district of a large Swedish city completed measures designed to assess their gender-based social preferences, stereotypes, and automatic encoding. Compared with children in typical preschools, a greater proportion of children in the gender-neutral school were interested in playing with unfamiliar other-gender children. In addition, children attending the gender-neutral preschool scored lower on a gender stereotyping measure than children attending typical preschools. Children at the gender-neutral school, however, were not less likely to automatically encode others' gender. The findings suggest that gender-neutral pedagogy has moderate effects on how children think and feel about people of different genders but might not affect children's tendency to spontaneously notice gender.

Gender Attitudes in Early Childhood: Behavioral Consequences and Cognitive Antecedents

This study examined factors that predicted children's gender intergroup attitudes at age 5 and the implications of these attitudes for intergroup behavior. Ethnically diverse children from low-income backgrounds (N = 246; Mexican-, Chinese-, Dominican-, and African American) were assessed at ages 4 and 5. On average, children reported positive same-gender and negative other-gender attitudes. Positive same-gender attitudes were associated with knowledge of gender stereotypes. In contrast, positive other-gender attitudes were associated with flexibility in gender cognitions (stereotype flexibility, gender consistency). Other-gender attitudes predicted gender-biased behavior. These patterns were observed in all ethnic groups. These findings suggest that early learning about gender categories shape young children's gender attitudes and that these gender attitudes already have consequences for children's intergroup behavior at age 5.

Young children perceive less humanness in outgroup faces

We investigated when young children first dehumanize outgroups. Across two studies, 5- and 6-year-olds were asked to rate how human they thought a set of ambiguous doll-human face morphs were. We manipulated whether these faces belonged to their gender in- or gender outgroup (Study 1) and to a geographically based in- or outgroup (Study 2). In both studies, the tendency to perceive outgroup faces as less human relative to ingroup faces increased with age. Explicit ingroup preference, in contrast, was present even in the youngest children and remained stable across age. These results demonstrate that children dehumanize outgroup members from relatively early in development and suggest that the tendency to do so may be partially distinguishable from intergroup preference. This research has important implications for our understanding of children's perception of humanness and the origins of intergroup bias.

Children's Lay Theories About Ingroups and Outgroups: Reconceptualizing Research on Prejudice

The consensus from the developmental literature examining children's intergroup attitudes has been that children as young as 3 years of age exhibit racial prejudice. We suggest, however, that as much of the developmental research has confounded ingroup positivity and outgroup negativity, it becomes difficult to determine whether young children are displaying ingroup bias or outgroup derogation. Furthermore, it appears that young children are not demonstrating hostility toward outgroups; studies that have separately assessed evaluations toward the ingroup and outgroup demonstrate that rather than evaluating the outgroup negatively, young children are demonstrating a positivity bias toward their ingroup. We propose, therefore, that young children are primarily utilizing a perceptually based lay theory that does not necessitate outgroup derogation. We argue, however, that children's lay theories are subject to social structural conditions and specific social transitions, and hence, can lead to the development of prejudice.

Stereotype Threat in der Grundschule

Zusammenfassung. Das Ziel der Studie war es zu untersuchen, ob bereits Grundschulkinder von Stereotype-Threat- beziehungsweise Lift-Effekten in ihrer Mathematikleistung beeinflusst werden. Dazu wurde auf eine implizite Manipulation zurückgegriffen, um Geschlechtsstereotype zu aktivieren, bevor ein Mathematiktest absolviert wurde. Bei Mädchen sollte die Aktivierung zu einer schlechteren Leistung führen, während für Jungen ein Leistungsvorsprung erwartet wurde. An der Untersuchung nahmen 120 Viertklässler teil (66 männlich, 54 weiblich, Alter M = 9.24, SD = 0.61). Hypothesenkonform ergab sich eine signifikante Interaktion zwischen Geschlecht und Stereotypaktivierung bei schwierigen Aufgaben. Während Mädchen in der Stereotypgruppe schlechter abschnitten als Mädchen in der Kontrollgruppe, konnte bei den Jungen kein Leistungsunterschied beobachtet werden. Die Ergebnisse bestätigen, dass Geschlechtsstereotype implizit bereits in der Grundschule die Mathematikleistung von Mädchen beeinträchtigen können.

Expertise in unexpected places: Children's acceptance of information from gender counter-stereotypical experts

The current study examined children's willingness to accept novel information from expert informants with nontraditional gender role interests. Four- to 8-year-olds heard conflicting information about traditionally feminine or masculine domains from a gender counter-stereotypical expert (e.g., a boy with expertise in ballet) and a layperson of the other gender (e.g., a girl with little knowledge about ballet). Participants were asked which informant was correct, who they would prefer to learn from in the future, and to rate their liking of each informant. Overall, participants selected the gender counter-stereotypical expert as correct. Four- to 5-year-olds reported a preference to learn from same-gender participants in the future irrespective of expertise, whereas 6- to 8-year-olds reported wanting to learn from counter-stereotypical experts. Boys showed relatively greater acceptance of information from a male counter-stereotypical expert than from a female counter-stereotypical expert. Although participants reported greater liking of same-gender informants, liking evaluations were largely positive irrespective of gender norm deviations. Implications for children's acceptance of gender nonconforming activities are discussed.

"The Cooties Effect": Amygdala Reactivity to Opposite- versus Same-sex Faces Declines from Childhood to Adolescence

One of the most important social identities that children learn to define themselves and others by is sex, becoming a salient social category by early childhood. Although older children begin to show greater flexibility in their gendered behaviors and attitudes, gender rigidity intensifies again around the time of puberty. In the current study, we assessed behavioral and neural biases to sex across a wide age group. Ninety-three youth (ages 7-17 years) provided behavioral rating of same- and opposite-sex attitudes, and 52 youth (ages 4-18 years) underwent an fMRI scan as they matched the emotion of same- and opposite-sex faces. We demonstrate significant age-related behavioral biases of sex that are mediated by differential amygdala response to opposite-sex relative to same-sex faces in children, an effect that completely attenuates by the teenage years. Moreover, we find a second peak in amygdala sensitivity to opposite-sex faces around the time of puberty. Thus, the amygdala codes for developmentally dependent and motivationally relevant social identification across development.

Young children's automatic encoding of social categories

The present research investigated young children's automatic encoding of two social categories that are highly relevant to adults: gender and race. Three- to 6-year-old participants learned facts about unfamiliar target children who varied in either gender or race and were asked to remember which facts went with which targets. When participants made mistakes, they were more likely to confuse targets of the same gender than targets of different genders, but they were equally likely to confuse targets within and across racial groups. However, a social preference measure indicated that participants were sensitive to both gender and race information. Participants with more racial diversity in their social environments were more likely to encode race, but did not have stronger racial preferences. These findings provide evidence that young children do not automatically encode all perceptible features of others. Further, gender may be a more fundamental social category than race.

Gendered-peer relationships in educational contexts

The goals of this chapter are to discuss the theories and evidence concerning the roles of gendered-peer interactions and relationships in children's lives at school. We begin by discussing the tendency of boys and girls to separate into same-sex peer groups and consider the theories and evidence concerning how gender segregation occurs and how peers influence children's learning and development. We then turn to the important and understudied question of why some children have more exposure to same-sex peers than others. We consider factors that contribute to variability in children's experiences with gender segregation such as the types of schools children attend and the kinds of classroom experiences they have with teachers. Finally, we review new evidence concerning the cognitive and affective factors that illustrate that children are actively involved in constructing the social world that surrounds them.

The roots of stereotype threat: when automatic associations disrupt girls' math performance

Although stereotype awareness is a prerequisite for stereotype threat effects (Steele & Aronson, 1995), research showed girls' deficit under stereotype threat before the emergence of math-gender stereotype awareness, and in the absence of stereotype endorsement. In a study including 240 six-year-old children, this paradox was addressed by testing whether automatic associations trigger stereotype threat in young girls. Whereas no indicators were found that children endorsed the math-gender stereotype, girls, but not boys, showed automatic associations consistent with the stereotype. Moreover, results showed that girls' automatic associations varied as a function of a manipulation regarding the stereotype content. Importantly, girls' math performance decreased in a stereotype-consistent, relative to a stereotype-inconsistent, condition and automatic associations mediated the relation between stereotype threat and performance.

Children's Use of Social Categories in Thinking About People and Social Relationships

A series of studies investigated White U.S. three- and four-year-old children's use of gender and race information to reason about their own and others' relationships and attributes. Three-year-old children used gender- but not race-based similarity between themselves and others to decide with whom they wanted to be friends, as well as to determine which children shared their own preferences for various social activities. Four-year-old (but not younger) children attended to gender and racial category membership to guide inferences about others' relationships, but did not use these categories to reason about others' shared activity preferences. Taken together, the findings provide evidence for three suggestions about these children's social category-based reasoning. First, gender is a more potent category than race. Second, social categories are initially recruited for first-person reasoning, but later become broad enough to support third-person inferences. Finally, at least for third-person reasoning, thinking about social categories is more attuned to social relationships than to shared attributes.

Differing levels of gender salience in preschool classrooms: effects on children's gender attitudes and intergroup bias

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.

Gender and racial favouritism in black and white preschool girls

The authors examined gender and racial preferential behaviour in 108 3- and 5-year-old Black and White girls. Children set up a birthday party for dolls that differed in gender and racial physical characteristics. Whereas White girls showed favouritism towards the doll most closely resembling themselves in both gender and race, Black girls showed most favouritism towards the White girl doll. Black girls were more likely to show preference based on gender rather than race, whereas White girls were equally likely to show race- or gender-based favouritism. Among White 5-year-olds, greater prior interaction with Blacks was positively associated with race-related favouritism (i.e., secondary preference to the White boy doll rather than the Black girl doll). Interracial contact was unrelated to racial favouritism among the other three groups. Results demonstrate the salience of gender identity during the preschool years, and indicate that majority/minority status and intergroup contact shape the development of collective identity and social behaviour.

Social categories guide young children's preferences for novel objects

To whom do children look when deciding on their own preferences? To address this question, 3-year-old children were asked to choose between objects or activities that were endorsed by unfamiliar people who differed in gender, race (White, Black), or age (child, adult). In Experiment 1, children demonstrated robust preferences for objects and activities endorsed by children of their own gender, but less consistent preferences for objects and activities endorsed by children of their own race. In Experiment 2, children selected objects and activities favored by people of their own gender and age. In neither study did most children acknowledge the influence of these social categories. These findings suggest that gender and age categories are encoded spontaneously and influence children's preferences and choices. For young children, gender and age may be more powerful guides to preferences than race.

Patterns of gender development

A comprehensive theory of gender development must describe and explain long-term developmental patterning and changes and how gender is experienced in the short term. This review considers multiple views on gender patterning, illustrated with contemporary research. First, because developmental research involves understanding normative patterns of change with age, several theoretically important topics illustrate gender development: how children come to recognize gender distinctions and understand stereotypes, and the emergence of prejudice and sexism. Second, developmental researchers study the stability of individual differences over time, which elucidates developmental processes. We review stability in two domains-sex segregation and activities/interests. Finally, a new approach advances understanding of developmental patterns, based on dynamic systems theory. Dynamic systems theory is a metatheoretical framework for studying stability and change, which developed from the study of complex and nonlinear systems in physics and mathematics. Some major features and examples show how dynamic approaches have been and could be applied in studying gender development.
