Perry,1 Rachel E. Pauletti,2 and Patrick J. Cooper2 Abstract We review theory and research on the assessment, development, and consequences of individual differences in gender identity, as studied among ordinary school children. Gender identity encompasses children’s appraisals of compatibility with, and motivation to fit in with, gender collectives; it is a multidimensional construct. Five dimensions of gender identity are considered in depth: felt same-gender typicality, felt other-gender typicality, gender contentedness, felt pressure for gender conformity, and intergroup bias. A host of cognitive, affective, social, and defensive processes contribute to these forms of gender identity, all of which in turn affect children’s psychosocial adjustment. Felt same-gender typicality promotes self-esteem and protects children from harmful effects of stressors, but it is associated with negative attitudes toward other-gender peers and activities unless children feel at least somewhat similar to the other gender as well. Felt other-gender typicality distresses children who do not also feel same-gender–typical. The other three gender identity variables encourage self-serving behavior (e.g., dominance) if children view it as appropriate for their gender. Children who feel genderatypical or discontent with their gender suffer considerable distress if they feel pressure for gender conformity. Gender contentedness may be a particularly powerful contributor to children’s adoption of gender-typed behavior. Keywords Gender identity, middle childhood, gender differences Introduction Recent years have witnessed an increased interest in children’s gender identity and the role it plays in children’s mental health and behavior. Gender identity may be defined as a set of cognitions encompassing a person’s appraisals of compatibility with, and motivation to fit in with, a gender collective. It is a multidimensional construct. One dimension of gender identity of central importance to theory and research is felt same-gender typicality, or people’s self-perceived similarity to their gender collective. Concern with this aspect of gender identity reflects a longstanding interest in the implications of people’s felt masculinity or femininity for their mental health and social behavior. These latter terms are rarely used today, owing to ambiguities in meaning, but the notion that felt compatibility with one’s gender is important remains alive. A major purpose of our review is to evaluate recent developments in the study of children’s felt same-gender typicality. However, conceptualizations of gender identity have expanded recently to include additional dimensions, such as people’s felt similarity to the other gender, satisfaction with their birth gender, felt pressure for gender conformity, and derogation of the other gender. These additional aspects of gender identity are important in their own right, but they also interact with felt same-gender typicality to affect children’s welfare. For example, children who feel dissimilar to same-gender peers face adjustment difficulties primarily if they also feel strong pressure for gender conformity or feel similar to the other gender. Thus, it is important to study different aspects of gender identity in conjunction with one another. This article reviews theory and research on the conceptualization, assessment, development, and consequences of these several dimensions of gender identity, as studied in ordinary populations of preadolescent school children. Our review draws heavily on a body of work by the first author and his colleagues over the last decade and a half but includes work by others where relevant. Our focus is on individual differences in gender identity among children of each sex. Preadolescence is a period when children undergo many personal and social experiences that are likely to affect their gender identity in lasting ways. Indeed, during the school years children tend to stabilize their positions (relative to their peers’) on the dimensions of gender identity we consider. In turn, their patterns of gender identity are important influences on their subsequent well-being and social behavior. Our review has four sections. First, we discuss the conceptualization and assessment of gender identity. Second, we summarize evidence on how gender identity develops. Third, we discuss the consequences of gender identity for children’s personal and social well-being as well as for their acquisition of gender-typed behaviors. Finally, we offer our conclusions. Conceptualization and Assessment of Gender Identity The view that gender identity (as well as other collective identities, e.g., ethnic identity) is multidimensional is now well accepted (Ashmore, Deaux, & McLaughlin-Volpe, 2004; Egan & Perry, 1 2 Department of Psychology, Florida Atlantic University, USA Department of Psychology, Lynn University, USA Corresponding author: David G. Perry, Department of Psychology, Florida Atlantic University, Boca Raton, FL 33431, USA. Email: perrydg@fau.edu 290 2001; Martin, Andrews, Englund, Zosuls, & Ruble, 2017; Perry & Pauletti, 2011; Tobin et al., 2010). Here we describe eight dimensions of gender identity, but our following literature review focuses principally on only five of them. Dimensions of Gender Identity 1. Gender self-categorization. Gender self-categorization refers to labeling the self as either a boy or a girl. For most children, this entails a simple binary decision consistent with their anatomy. This is the earliest-developing form of gender identity and is sometimes called basic gender identity. Nearly all children label themselves correctly by age 3 years, and by age 6 years most have conserved gender, or realize that their gender remains invariant despite superficial changes in clothing, hair length, and so forth (Diamond & Butterworth, 2008; Kohlberg, 1969; Ruble, Martin, & Berenbaum, 2006). Because this aspect of gender identity usually is fully developed by age 6 years, it is rarely studied past that age. The remaining dimensions of gender identity capture individual differences among children of a given gender, are studied among older children, and are the focus of our review. 2. Felt same-gender typicality and 3. felt other-gender typicality. Felt same-gender typicality and felt other-gender typicality refer, respectively, to children’s self-perceived similarity to peers of their own gender and to peers of the other gender. Historically, these two aspects of gender identity were construed to be polar opposites (i.e., as perfectly negatively correlated), but arguments by Bem (1981), Constantinople (1973), and Spence, Helmreich, and Stapp (1975) inspired researchers to assess them separately. This permitted evaluation of new hypotheses, such as Bem’s belief that perceiving the self to be similar to both genders— psychological androgyny—is healthier than perceiving the self as similar only to one. Prior theorists had assumed that identifying more strongly with one’s own gender (and therefore less with the other) was superior. To assess children’s felt same-gender typicality or their felt other-gender typicality, children rate their similarity to samegender or other-gender peers on several dimensions (e.g., personality, interests, competencies) as well as on overall similarity (Egan & Perry, 2001; Martin et al., 2017; Pauletti, Menon, Cooper, Aults, & Perry, 2017). Contrary to earlier beliefs, children’s felt samegender typicality and felt other-gender typicality are only moderately negatively correlated, about 0.40 (Martin et al., 2017; Menon, 2006; Pauletti et al., 2017). This assessment strategy departs from the common practice of inferring children’s felt female typicality and felt male typicality from self-ratings on communal and agentic personality traits, respectively (e.g., Bem, 1981). This is for several reasons. First, children differ in their conceptions of the typical male or female (Edelbrock & Sugawara, 1978; Martin, 2000; Schmader & Block, 2015; Spence, 1985), and some children may not perceive these personality traits (or other researcher-supplied exemplars of female- and male-typicality) as relevant to their gender typicality (Egan & Perry, 2001; Spence & Hall, 1996). Second, because children’s gender-typed attributes in one domain (e.g., personality traits) are weakly correlated with their gender-typed attributes in other domains (e.g., activity preferences, sexual orientation; Ruble et al., 2006; Spence & Hall, 1996; Spence & Helmreich, 1980), it is hazardous to infer felt gender typicality from self-perceptions in any single domain. Third, in several theories (e.g., Tobin et al., International Journal of Behavioral Development 43(4) 2010), gender identity and self-perception of specific gendertyped attributes are distinct constructs and therefore require independent assessment. 4. Gender contentedness. Gender contentedness refers to children’s satisfaction with their gender assignment (e.g., being born female rather than male; Egan & Perry, 2001). It is not merely children’s evaluation of their own gender but rather involves children comparing the advantages and disadvantages of being male versus female (e.g., rating whether they sometimes wish they were the other gender). It correlates about 0.30 with felt same-gender typicality and about 0.50 with felt other-gender typicality (Pauletti et al., 2017). Very low scores indicate some degree of gender dysphoria. 5. Felt pressure for gender differentiation. Felt pressure for gender differentiation captures children’s motivation to avoid cross-gender behavior. It is measured as children’s anticipation of negative consequences (e.g., ridicule, criticism, shaming) from parents, peers, and the self for cross-gender behavior (Egan & Perry, 2001). It typically is uncorrelated with felt same-gender typicality, negatively correlated with felt other-gender typicality (around 0.40), and positively correlated with gender contentedness (around 0.20). Felt pressure for gender differentiation is a dimension of gender identity that resembles Bem’s (1981, 1985) construct of a gender schema—a pernicious predisposition to perceive the world through a gendered lens, to view the genders as polar opposites, to classify behavioral options in terms of gender appropriateness, and to adopt same-gender-stereotyped attributes and eschew other-gender ones. Bem believed that such a schema develops in people who internalize societal sanctions against cross-gender behavior, and she saw it as harmful because it may lead people to rule out potentially satisfying cross-gender options. Bem did not develop a direct measure of this schema, but she believed it could be inferred from a pattern of gender identity characterized by high felt same-gender typicality and low felt other-gender typicality. Children with this pattern of gender identity do report higher felt pressure for gender differentiation than children with other combinations of scores on the two felt typicality measures (Pauletti et al., 2017), but this association is not strong enough to conclude that a gender schema can be inferred from this pattern of felt typicality scores. To assess felt pressure for gender conformity, it should be measured directly and separately from other dimensions of gender identity. 6. Intergroup bias. Intergroup bias is the tendency to see one’s own gender (the in-group) more favorably than the other (e.g., as friendlier and smarter, less boring and lazy; Egan & Perry, 2001). It is part of a cluster of correlated intergroup cognitions that also includes tendencies to exaggerate differences between the genders and to homogenize the other gender (Bigler & Liben, 2007; Powlishta, 1995; Tajfel & Turner, 1979). It sometimes is modestly correlated with gender contentedness and felt pressure for gender conformity. 7. Gender centrality. Gender centrality is the importance a child attaches to gender as an aspect of her or his identity. To measure this, children may be asked to rank the importance of being a girl or a boy relative to their other identities (e.g., student, athlete, son/daughter; Luhtanen & Crocker, 1992; Lurye, Zosuls, & Ruble, 2008; Rogers & Meltzoff, 2014; Ruble et al., 2006). It is unrelated to other gender identity measures for girls but for boys is modestly negatively correlated with felt other-gender typicality and moderately positively correlated with gender contentedness as well as with felt pressure for gender conformity (Pauletti et al., 2017). Perry et al. 8. Gender frustration. Gender frustration refers to feelings of injustice and dismay that certain activities are off limits because they are considered (by self or others) to be more appropriate for the other gender than for one’s own. Such frustration tends to be stronger among children who may be experiencing some degree of cross-gender identity, that is, children with low felt same-gender typicality, high felt other-gender typicality, or low gender contentedness (Pauletti et al., 2017). Comment on Gender Identity Measures A few comments on these measures of children’s gender identity are in order: These measures tap consciously accessible (explicit) aspects of gender identity. There has been some effort to assess children’s unconscious (implicit) gender identity (Cvencek, Meltzoff, & Greenwald, 2011), but such work is new and limited. Thus, our review focuses on explicit aspects of children’s gender identity. Children’s gender identity is influenced by the child’s immediate context (e.g., being the only girl in a large group, being teased for gender nonconformity; Bigler, 1995; Deaux & Major, 1987; Mehta, 2015). Such temporary influences are not a main focus of our review, though later we suggest that how children process such temporary fluctuations in their gender identity may be affected by more stable components of their gender identity. We do not consider sexual orientation (sexual identity) to be an aspect of gender identity. Instead, we regard sexual orientation to be self-perception of a specific gender-typed attribute that may result from, or contribute to, one or more forms of gender identity (e.g., gender contentedness). Although extreme scores on certain gender identity measures may have clinical relevance, the measures we discuss here have not been developed for diagnostic purposes but rather for research designed to understand how gender identity operates among ordinary school children. Nonetheless, the research we review does have implications for practical application, as we suggest later. It should be clear that gender identity refers to self-reported cognitive constructions, not objective assessments, of children’s gendered qualities. Observable gendered qualities sometimes influence, or are influenced by, children’s gender identity, but they are not necessarily correlated with gender identity. A child’s gender identity is distinct from the gender stereotypes the child harbors (Tobin et al., 2010). Gender stereotypes are beliefs about how the sexes differ (descriptive stereotypes) or should differ (prescriptive stereotypes). Such beliefs sometimes interact with gender identity to affect children’s well-being and behavior, but they are not systematically correlated with gender identity. Although we described eight dimensions of gender identity, our review focuses on only five. Gender self-categorization is excluded because of scant individual differences among school children. Gender centrality and gender frustration are also excluded because they have received scant research attention, making it difficult to draw conclusions about them. 291 Development of Gender Identity Overview When discussing their development, it is useful to divide the dimensions of gender identity into two categories—those that rest on children’s perceptions of differences between the genders and those that rest on children’s perceptions of differences among children of a given gender. These may be called, respectively, between-gender and within-gender forms of gender identity. Here we elaborate this distinction and discuss some issues relevant to the development of each type. Three forms of gender identity rest on children’s perceptions of differences between the genders—gender contentedness, felt pressure for gender differentiation, and intergroup bias. These betweengender forms of gender identity are seen as early as the preschool years and may be outgrowths of the intergroup cognitions noted earlier (exaggeration of differences between the genders, preferential treatment of the in-group, devaluation and homogenization of the out-group). These cognitions and the forms of identity they inspire are fairly normative for preschoolers (Harris, 1995; Ruble et al., 2006) and may serve an evolutionary function by orienting children to the same-sex peer group as the collective after which they must pattern their behavior for eventual reproductive success (and related gender-differentiated behaviors; Harris, 1995). That is, they may promote the marked sex-segregation that characterizes children’s social groups over the next decade and facilitates their acquisition of gender-typed behaviors (Maccoby, 1998; Ruble et al., 2006). Intergroup bias and felt pressure for gender differentiation tend to decline over the school years. However, gender contentedness tends to remain high (Egan & Perry, 2001; Rogers & Meltzoff, 2014). Although all three between-gender forms of gender identity may have common roots in intergroup cognitions and fulfill similar early functions, other factors also contribute to the development of each, as described below. The result is that different children develop different patterns of these forms of gender identity, leading to the modest correlations among them. Felt same-gender typicality and felt other-gender typicality rest on children’s perceptions of differences among children of a given gender and thus may be considered within-gender forms of gender identity. Preschoolers sometimes gauge (and comment on) their similarity to persons of a given gender, perhaps noticing an obvious commonality, but it is probably not until children move into the school years that they possess the cognitive abilities (e.g., social comparison, comparison to a prototype) necessary to appraise their overall similarity to a gender collective (Carver, Yunger, & Perry, 2003; Egan & Perry, 2001). Felt same-gender typicality tends to increase through preadolescence, but felt other-gender typicality follows no clear age trend (Pauletti et al., 2017). Thus, during the early elementary school years, for most children gender identity development involves a rebalancing of their gender identity portfolio—letting go of immature between-gender forms of gender identity (especially felt pressure for gender differentiation and intergroup bias) and adding the ability to formulate within-gender forms of gender identity. Nonetheless, throughout the school years considerable individual differences exist among children of each gender on all dimensions of gender identity. Below we discuss the development of each form of gender identity. We start by summarizing what leads some children to persist in, or even to initiate, between-gender forms of gender 292 identity post-preschool. We then turn to influences on withingender types of gender identity. Throughout this article, all effects described as longitudinal, or as occurring over time, control for initial level of the dependent variable. Development of Between-Gender Forms of Gender Identity By late elementary school, fairly stable individual differences in each between-gender form of gender identity have developed. A few words about the development of each of these forms of gender identity are in order. Gender contentedness. Most children are fairly content with their birth gender, but some express dissatisfaction. This is more common for girls (Carver et al., 2003; Egan & Perry, 2001). Indeed, today girls are more likely than boys to be referred to a clinic for gender dysphoria, reversing a previous trend showing this to be more common for boys (Aitken et al., 2015). Reasons for the greater female discontent are unclear but may include the greater status and other advantages enjoyed by males as well as boys’ greater reluctance to acknowledge gender discontent. For boys, cross-sex interests tend to undermine popularity with peers and to invite victimization; for girls, cross-gender interests are more likely to enhance popularity (Braun & Davidson, 2017; Pauletti, Cooper, & Perry, 2014). Gender contentedness may be undermined by the desire to possess one or more cross-gender attributes, especially if perceived as off-limits for one’s own gender. Such other-gender desiderata may include personality traits, activity interests, nonverbal stylistic attributes, playmate preferences, relationships styles, physical attributes, sexual orientation, and still other qualities. Genderdiscontent children do often have cross-gender interests and traits (Carver et al., 2003; Carver, Egan, & Perry, 2004; Egan & Perry, 2001; Hines, 2015; Menon, 2006; Steensma, Biemond, de Boer, & Cohen-Kettenis, 2011). Further, as early as elementary school some children question their heterosexuality (i.e., do not anticipate a heterosexual future) and grow increasingly dissatisfied with their gender over time (Carver et al., 2004). Gender contentedness may also be undermined by repugnance toward one’s anatomy or certain behaviors expected of one’s gender. Attachment security—a child’s belief that a parent (or friend) is available for help if needed for relief from distress or for support of exploration—is associated with gender contentedness. Attachment security is a cognitive and emotional resource that helps children not only cope with stress but also to develop self-worth, selfconfidence, and communal relations with age-appropriate interaction partners (e.g., same-gender peers; Sroufe & Fleeson, 1986). Insecure attachment (e.g., avoidance of intimacy or fear of rejection) is associated with gender discontent, especially if the attachment is gender-atypical in nature (avoidant for girls, anxious for boys; Cooper et al., 2013; Menon, 2011, 2017; Pauletti, Cooper, Aults, Hodges, & Perry, 2016). Indeed, boys referred to clinics for gender dysphoria often display an anxious, clingy attachment to their mother (Zucker, Bradley, & Sullivan, 1996). Possibly, attachment insecurity encourages children who perceive a salient crossgender attribute in themselves to conclude that an other-gender identity would suit them better than a same-gender one. Cognitive inflexibility may also contribute to gender dissatisfaction. Rigidity of thought is a characteristic of autistic children, and autistic children show an elevated rate of gender dysphoria (de International Journal of Behavioral Development 43(4) Vries, Noens, Cohen-Kettenis, Berckelaer-Onnes, & Doreleijers, 2010). Similar to attachment insecurity, cognitive rigidity may lead children who perceive themselves to possess a salient cross-gender attribute to speculate that they might be happier were they the other gender (Hines, 2015). Gender contentedness is also associated with several biological factors (e.g., genes, prenatal and pubertal hormones, brain development, temperament). Such factors may influence children’s desires for, or possession of, gender-typed qualities that affect gender contentedness, or they may influence gender contentedness more directly (Hines, 2015; Ruble et al., 2006; Steensma et al., 2011). All of the foregoing factors may contribute to variations in children’s gender contentedness. Moreover, no single factor appears to be either necessary or sufficient to cause gender discontent. Thus, there likely exist multiple routes to gender dissatisfaction (as well as to the other forms of gender identity, considered later). Links between early expressions of gender dissatisfaction (e.g., a child’s occasional interest in cross-dressing) and subsequent serious gender dysphoria are not well understood (Hines, 2015). Young children who wish they were the other gender usually outgrow this wish by age 10 or 11 years (Steensma et al., 2011). One challenge for future research is to identify moderator variables that predict which children persist in this wish into adolescence. Another question is whether all cases of serious gender dysphoria in adolescence and adulthood are preceded by a clear wish to be the other gender in childhood; perhaps some cases are preceded by milder forms of gender dissatisfaction in earlier years. Given that serious gender dysphoria in later years leads some people to consider a profound, usually irreversible, life-altering decision— changing their gender—it is unfortunate that so little is known about its origins in childhood. Felt pressure for gender differentiation. Like gender contentedness, felt pressure for gender conformity is stronger for boys than girls (Egan & Perry, 2001). This may reflect the greater stigma for gender-atypical behavior boys experience (Ruble et al., 2006), but no study has assessed the pressures children actually experience (from parents, peers, media, etc.) and related them to children’s felt pressure for gender conformity. This is unfortunate given that a cornerstone principle of several theories is that children who experience strong social pressure for gender conformity eventually internalize the prescriptive and proscriptive messages and selfregulate accordingly (Bem, 1981; Bussey & Bandura, 1999; Mischel, 1970; Perry & Bussey, 1984). Children do increasingly resemble their friends’ level of felt pressure over time, however, suggesting that socialization of felt pressure does occur, perhaps via peer-group discussions and modeling (Kornienko, Santos, Martin, & Granger, 2016). Insecure maternal attachment (either avoidant or anxious) is associated with felt pressure for gender differentiation, for both girls and boys (Cooper et al., 2013; Pauletti et al., 2016). Moreover, for boys an anxious style of relating to close friends predicts increased felt pressure for gender conformity over time (Jackson, 2013). Other sources of insecurity contribute to felt pressure too. Victimization by peers, internalizing difficulties, and low selfefficacy for dominance or sports all portend increased felt pressure for gender differentiation (Jackson, 2013; Yunger, Carver, & Perry, 2004). Three explanations for the contribution of insecurity to felt pressure for gender conformity are noteworthy. Perry et al. First, because stress and insecurity retard normative developmental transitions (Fischer, 1980; Sroufe & Fleeson, 1986), they may lock children into—or cause them to regress to—primitive modes of thinking that encourage felt pressure for gender conformity, such as intergroup cognitions or an entity theory of gender (the belief that gender differences are biological and immutable). Second, insecurity spawns fear-based avoidance motives rather than reward-based approach motives (Higgins, 2012), and fear of punishment for other-gender behavior represents an avoidance motive. Third, a large social-psychology literature indicates that when people feel anxious, helpless, or powerless, they tend to categorize people into we versus they, endorse social constraints and punishments that maintain the distinction between the in-group and the out-group, denigrate the out-group and inhibit behaviors typical of it, and derive psychological benefits (e.g., self-esteem) from engaging in these defensive maneuvers (Greenberg, Solomon, & Arndt, 2008; Pyszczynski, Greenberg, Koole, & Solomon, 2010). Perhaps insecure children adopt gender-differentiating self-guides because they provide solace. That is, gender self-guides may offer them a clear and reassuring roadmap for navigating a world they otherwise would experience as frightening and unpredictable (Yunger et al., 2004). Intergroup bias. Girls are more likely than boys to express ingroup favoritism—to attribute more positive and fewer negative qualities to their own gender collective than to the other (Carver et al., 2003; Egan & Perry, 2001). The reasons for this are unclear, though it may reflect girls’ tendencies to experience boys as bossy, rough, and aversive (Maccoby, 1998). Little is known about the causes of individual differences in intergroup bias. However, children increasingly resemble their friends’ intergroup bias over time, raising the possibility of peer socialization (Kornienko et al., 2016). Also, low self-confidence (poor self-esteem and low self-efficacy for sports or for dominance) contributes to intergroup bias over time (Jackson, 2013), perhaps for the same reasons that insecurity fosters felt pressure for gender conformity. Development of Within-Gender Forms of Gender Identity By age 3 years, between-gender forms of gender identity are likely to have spurred most children to interact primarily with samegender peers and to value fitting in with them. By elementary school, children possess the cognitive capabilities necessary to compare themselves to peers of a given gender on genderdifferentiated attributes and to estimate their overall similarity to peers of that gender (Egan & Perry, 2001; Harter, 2006). It is unclear how often children formulate such estimates spontaneously on their own versus in response to contextual cues (e.g., peer teasing, requests from researchers), but elementary school (and older preschool) children can and do produce reliable and stable estimates of their same- and other-gender typicality when requested (Martin et al., 2017; Pauletti et al., 2017). Here we summarize theory and research on how these estimates develop. Felt same-gender typicality. According to several cognitive theories (Egan & Perry, 2001; Martin, 2000; Perry & Bussey, 1979; Spence, 1985; Spence & Buckner, 1995; Tobin et al., 2010), children develop conceptions of the typical or ideal person of their gender and occasionally compare their own qualities to these standards to estimate their similarity to their gender 293 collective. These theories further suggest that children differ not only in the particular gender-typed characteristics they possess but also in their conceptions of the typical or ideal person of their gender. Thus, to reach conclusions about their gender typicality, each child employs an idiosyncratic calculus that weights her or his gender-typed attributes according to their salience and positions in a personal hierarchy of perceived importance. Presumably, most children most of the time are able to identify in themselves a sufficient amount of gender-congruent attributes to feel comfortably gender typical and acceptable to peers (and hence themselves). Occasionally, however, children may perceive a salient shortcoming in their gender typing that threatens their felt typicality (e.g., a girl who believes beauty is essential for females realizes she is unattractive). Such instances motivate children to adopt a replacement gender-typed attribute, or at least to assign greater weight to alternate gender-typed attributes that they do possess, so that their summary estimate of gender typicality can return to a higher level (Spence & Hall, 1996). However, some children experience chronic felt gender atypicality. They may have difficulty cognitively repairing temporary threats to their typicality, or they may perceive in themselves a salient (and perhaps unwanted) cross-gender attribute that they fear will last a long time. The 10-year-old girl who prefers rough play with boys over interaction with other girls or the 13-year-old boy who is coming to realize he is gay may struggle with a profound sense of gender atypicality lasting many formative years. The hypothesis that children’s self-perceptions of gender-typed characteristics influence their felt same-gender typicality is well supported. Indirect evidence comes from the fact that boys score higher than girls on felt same-gender typicality. This supports the hypothesis because boys tend to be more gender-typed in their activity preferences than girls (Ruble et al., 2006), and thus boys on average have a stronger behavioral basis for inferring samegender typicality. More direct evidence comes from studies relating children’s self-perceptions of gender-typed attributes to their felt samegender typicality. In one study, children’s self-perceptions on seven dimensions of gender typing (same-gender interests, other-gender interests, same-gender traits, other-gender traits, liking for samegender peers, liking for other-gender peers, and expectation of a heterosexual future) cumulatively accounted for about one-third of the variance in children’s felt same-gender typicality (Egan & Perry, 2001). Other studies suggest similar conclusions (Carver et al., 2003; Corby, Hodges, & Perry, 2007; Martin et al., 2017; Vantieghem, Vermeersch, & van Houtte, 2014). Moreover, certain gender-typed attributes predict change in felt same-gender typicality over time. For example, children who do not expect a heterosexual future or who view themselves as relating to parents or friends in a gender-atypical away (avoidant for girls, anxious for boys) feel decreasingly gender-typical over time (Carver et al., 2004; Jackson, 2013; Menon, 2017). A limitation of these studies is that they did not assess children’s conceptions of the attributes that make for the ideal or typical child of their gender and thus could not test the hypothesis that children estimate their gender typicality by weighting their attributes according to their ranks in a personal hierarchy of gender relevance. However, a study by Menon (2006) supported the full model. In this study, children’s felt same-gender typicality was concurrently associated with the degree to which children’s self-perceptions of 62 behaviors matched the children’s ratings of the gender appropriateness of the behaviors. (For each child, a correlation was computed 294 between the child’s 62 self-perception ratings and the child’s 62 ratings of same-gender appropriateness, and these per-child correlations predicted children’s felt gender typicality.) Despite its appeal, the cognitive model may overstate the complexity of many children’s (and adults’) estimates of their gender typicality. Perhaps many people assess their gender typicality more economically on the basis of a small number of highly genderdifferentiated attributes. Indeed, perceiving the self to possess even a single salient cross-sex attribute (e.g., a sexual orientation, mannerism, or activity preference characteristic of the other gender) may be enough to undermine many persons’ felt same-gender typicality, perhaps especially if they feel pressure for gender conformity. Research is needed to determine how the content and breadth of children’s criteria for feeling gender typical—their “contingencies of gender typicality”—develop. Cognitive explanations have dominated theories about the development of felt same-gender typicality. However, social and emotional factors appear to play a role as well. For example, secure attachment to parents or friends promotes felt same-gender typicality whereas avoidant or anxious attachment (especially when gender-atypical) undermines it (Cooper et al., 2013; Menon, 2011, 2017; Pauletti et al., 2014, 2016). Felt other-gender typicality. Little attention has been paid to the development of felt other-gender typicality, but it is reasonable to assume that self-observation of salient other-gender attributes contributes to this index of gender identity (Martin et al., 2017; Pauletti et al., 2017). Girls engage in more cross-gender behavior than boys do (Ruble et al., 2006), and girls score far higher than boys on felt other-gender typicality. Moreover, the Menon (2006) study (which showed that children’s felt same-gender typicality could be predicted from their self-perceptions of behaviors rated as same-gender-appropriate) included a measure of felt othergender typicality; this measure was positively correlated with children’s self-perceptions of behaviors they rated as crossgender-appropriate (and negatively correlated with their selfperceptions of behaviors they viewed as same-gender-appropriate). Felt other-gender typicality is negatively correlated not only with felt same-gender typicality but also with gender contentedness and felt pressure for gender differentiation. Low levels of these other forms of gender identity may encourage children to interact with other-gender peers, reduce the time they spend with samegender peers, and lead them to develop cross-gender behaviors; this is likely to result in self-appraisals of similarity to the other gender (Kornienko et al., 2016; Martin et al., 2017). Two other cognitive features of children who feel other-gendertypical are noteworthy. First, these children eschew the belief that gender differences are biologically fixed (entity theory of gender); instead, they believe that boys can learn to be like girls and vice versa (Menon, 2006). Second, these children (especially girls) score high on gender frustration (Pauletti et al., 2017), that is, they find societal prohibitions against behaving in other-gender ways to be unjust and distressing. The causal relations between felt othergender typicality and these other variables have yet to be unraveled, but they suggest that children who acknowledge similarity to the other gender possess a rather sophisticated, liberated attitude toward gender roles. Their identification with their own gender may be somewhat weaker than other children’s (their gender contentedness and felt same-gender typicality are lower), but they do not believe that gender differences are biologically rooted, they are cognizant of—and bothered by—the injustice of prohibitions against cross-gender behavior, and they reject these prohibitions International Journal of Behavioral Development 43(4) as guides for their own behavior (they feel little pressure to avoid other-gender behavior). Comment on the Development of Gender Identity Much remains to be learned about the development of individual differences in gender identity. The lack of research examining influences of the social environment on children’s gender identity is especially surprising given the central role such influences are thought to play in the development of felt pressure for gender conformity (Bem, 1993; Bussey & Bandura, 1999). Children do increasingly resemble their friends’ felt pressure and intergroup bias (Kornienko et al., 2016), but the mediating social mechanisms have yet to be identified. Also surprising is the ubiquitous role that feelings of security versus insecurity play in gender identity development. Consistent with attachment theory (Cooper et al., 2013; Sroufe, Bennett, Englund, Urban, & Shulman, 1993), secure attachment supports two forms of gender identity that are normative for school children (gender contentedness and felt same-gender typicality), whereas insecure attachment supports two forms that usually decline over the school years and tend to cause adjustment problems (felt pressure for gender differentiation and intergroup bias). Other sources of insecurity besides attachment insecurity also contribute to felt pressure for gender conformity (e.g., social anxiety, victimization by peers). Perhaps felt pressure for gender differentiation is a defensive reaction latched onto by insecure children because it gives them comfort, that is, insecure children may believe (unconsciously) that gender conformity will earn them peer acceptance and stave off feelings of insecurity. More research on possible biological contributions to individual differences in gender identity is needed. Although some inroads on this topic have been made (Hines, 2015; Ruble et al., 2006), firm conclusions are not yet available. Studies examining how biological factors interact with cognitive, social, and behavioral variables to affect gender identity may prove particularly informative. Consequences of Gender Identity We now consider the ways that gender identity influences children’s (a) psychosocial adjustment and (b) adoption of gendertyped behaviors. We start by summarizing theory, then review the relevant research. Theory: Past and Present Gender identity and adjustment. A longstanding, central hypothesis of most theories of gender development is that children who feel compatible with their gender—who are content with their gender and feel similar to others of their gender—experience better personal and social adjustment (e.g., self-esteem, peer acceptance) than children less comfortable with their gender (Bailey & Zucker, 1995; Egan & Perry, 2001; Kagan, 1964; Kohlberg, 1966; Spence & Buckner, 1995). Presumably, the latter children fear ostracism, denial of privileges, or loss of protection from peers (Bugental & Goodnow, 1998; Caporael & Brewer, 1991) or simply feel inadequate as group members (Kohlberg, 1969; Tajfel, 1982). Thus, children who are dissatisfied with their gender or view themselves as gender-atypical are expected to suffer anxiety, sadness, low selfesteem, social withdrawal, self-deprecation, and other forms of Perry et al. distress; this in turn may lead them to experience peer rejection or victimization (e.g., Perry, Kusel, & Perry, 1988). These hypotheses remain popular and receive support. However, we shall see that neither high gender contentedness nor high felt same-gender typicality is always an unmitigated blessing. For example, if children endorse stereotypes specifying that their gender is superior to the other, then high gender contentedness fosters narcissism; and if children view themselves as very dissimilar to the other gender, then high felt same-gender typicality is associated with gender-polarizing cognition (e.g., sexist stereotypes, ingroup favoritism). Moreover, neither low gender contentedness nor low felt same-gender typicality inevitably causes children distress: it is mainly when children feel pressure for gender conformity that felt incompatibility with their gender causes them problems. Such qualifications indicate that the effects of felt same-gender compatibility depend on other factors in a child’s psyche. Here we describe four interaction hypotheses that help organize the data we later review concerning the ways that children’s gender identity affects their personal and social adjustment. First is Bem’s (1981, 1993) androgyny hypothesis. In her influential theory of psychological androgyny, Bem (1981, 1993) proposed that felt same-gender typicality interacts with felt othergender typicality to affect mental health. She suggested that high felt same-gender similarity is healthy only if people also view themselves as similar to the other gender. She argued that persons who view themselves as similar only to their own gender have internalized their culture’s pressure for gender conformity and possess the harmful gender schema she described. This was expected to cause them frustration, unhappiness, gender-polarizing cognition, rigidity in gendered behavior and thought, and relationship difficulties. Although Bem believed that people who view themselves as similar to both genders lack this crippling gender straitjacket, she did not suggest they deliberately strive to be similar to persons of both genders (i.e., to be both “masculine” and “feminine”). Instead, she believed that androgynous persons are equipped to acquire qualities of both genders because gender is simply irrelevant to their identity and life choices. There are problems with Bem’s (1981, 1993) theorizing (e.g., people may regard themselves as more similar to their own gender than to the other for reasons other than a crippling gender schema) and with her research methods (e.g., Bem relied on self-perceptions of agentic and communal traits to assess male typicality and female typicality, respectively). These limitations rendered much of the early research on her ideas hard to interpret (for critiques, see Spence & Buckner, 1995; Tobin et al., 2010). However, as we shall see, recent studies that overcome the limitations support Bem’s belief that viewing the self as similar to both genders offers certain advantages over viewing the self as similar to only one. A second interaction hypothesis is the stereotype emulation hypothesis, or the idea that gender identity motivates children to adopt attributes they have encoded as appropriate for their gender (e.g., Martin, 2000; Tobin et al., 2010). Stereotype emulation is believed to contribute to children’s adoption of gender-typed behaviors, discussed later, but because many gender-typed attributes also capture aspects of children’s adjustment (e.g., aggression, depression, sports efficacy, nurturance), the hypothesis is relevant here as well. We shall see that the three between-gender forms of gender identity (gender contentedness, felt pressure for gender conformity, and intergroup bias) are especially likely to combine with children’s gender stereotypes to affect their well-being, often in ways harmful to them or their interaction partners. 295 Third is the gender self-discrepancy hypothesis, or the idea that low felt same-gender compatibility (low gender contentedness or low felt same-gender typicality) causes distress among children who possess strongly gender-differentiating cognition (e.g., felt pressure for gender differentiation, prescriptive stereotypes that mandate gender differences, entity theory of gender). Presumably, the combination of felt gender incompatibility with strong gender standards creates a painful gender self-discrepancy—a gap between the need to be gender-conforming and the realization that one is failing. Such gaps can create intense distress, frustration, loss of self-regulatory control, aggression, and other problems (Carver et al., 2003; Cooper, 2014; Egan & Perry, 2001; Higgins, 1987; Pauletti et al., 2014). Fourth, is a protective function hypothesis, or the idea that strong felt same-gender compatibility protects children from the potentially harmful effects of certain cognitive, behavioral, and social risk factors (Yunger, Vagi, Corby, & Perry, 2003). We shall see that felt same-gender typicality uniquely serves in this protective capacity, possibly by imparting a sense of security that helps children cope with stressors. Gender identity and gender typing. Gender identity has also been suggested to affect children’s gender typing—their genderdifferentiated recreational interests, academic pursuits, personality traits, choices of playmates, relationship styles, mannerisms, clothing choices, and so forth. Two pathways by which gender identity influences children’s adoption of gender-typed attributes have received the most attention. First, in a peer-socialization pathway, gender identity affects the gender(s) of children’s preferred interaction partners as well as children’s susceptibility to influence by peers of each gender. Harris (1995) offered a cogent two-process developmental theory of peer socialization of gender that, with amplification, provides a useful framework for considering the role of gender identity in this pathway. Harris (1995) proposed that peer socialization of gender gets underway in an initial process of between-gender differentiation. In this process, early gender identity (gender self-categorization) and associated intergroup cognitions (in-group favoritism, homogenization of the out-group) lead young children to interact primarily with peers of their own gender. This results in sex-segregated interaction. Harris viewed this process as a fairly normative one with few individual differences. However, not all children play exclusively with same-gender peers, and individual differences in gender identity may influence the gender mix of children’s preferred interaction partners, leading some children to interact mainly with same-gender peers, some to interact with a mix of male and female peers, and a few to interact mainly with other-gender peers. For example, gender identity may affect the assumptions children make about their likely compatibility with peers of a particular gender or affect the personal and social consequences children anticipate for associating with peers of a particular gender (Bussey & Bandura, 1999; Bussey & Perry, 1976; Kagan, 1964; Kohlberg, 1969; Martin, 2000). All five dimensions of gender identity may participate in such ways (with felt other-gender typicality predicting lesser rather than greater interest in same-sex peers). Once between-gender differentiation is underway, Harris’ (1995) second process of within-gender differentiation begins. In this process, different children of the same gender develop different same-gender-typed attributes, with each child’s attributes depending on the particular same-gender peer subgroup(s) the child has joined as well as the child’s unique temperament, interests, 296 abilities, opportunities, and values. Gender identity may matter here too. Because children are attracted to same-gender peers whose behaviors, attitudes, relationship styles, and other attributes resemble their own (Hodges, Finnegan, & Perry, 1999; Rubin et al., 2006), they may gravitate toward same-gender peers whose gender identity resembles their own; further, they may be particularly subject to influence by these peers’ behaviors, attitudes, and identities (Kornienko et al., 2016). For example, girls who view themselves as very girly may befriend each other and interact in ways that cause them both to behave hyper-femininely. Again, all five gender identity variables may contribute. A second pathway via which gender identity influences children’s gender-typing is a self-socialization pathway. This involves the stereotype emulation mechanism described earlier. As children age, they increasingly represent gender differences cognitively in the form of descriptive and prescriptive stereotypes, acquired mainly by observing differences between the sexes in their behaviors. In the self-socialization pathway, gender identity leads children to adopt behaviors they have encoded as same-gender appropriate (Bem, 1993; Kohlberg, 1969; Liben & Bigler, 2002; Maccoby, 1988; Martin & Halverson, 1981; Martin, Ruble, & Szkrybalo, 2002; Perry, Pauletti, Cooper, & Handrinos, 2012; Tobin et al., 2010). Although all five gender identity variables may fuel both peersocialization and self-socialization of gender typing, two gender identity dimensions have received more attention than the others in theoretical accounts—felt same-gender typicality and felt pressure for gender conformity. Perceived similarity has long been suggested to foster children’s attraction to, and imitation of, similar others, not only in cognitive-developmental theories (Kagan, 1964; Kohlberg, 1969; Martin, 2000; Ruble et al., 2006) but also in socialcognitive accounts (Bandura, 1986; Bussey & Perry, 1976; Perry & Bussey, 1979; Tobin et al., 2010). Internalized social pressure has also been assigned importance, especially in social-cognitive accounts (Bandura, 1986; Bem, 1993; Bussey & Bandura, 1999; Liben & Bigler, 2002; Mischel, 1970). Other forms of gender identity have been given short shrift. We later contend that this may be an unfortunate oversight. There may be other ways in which gender identity affects children’s gender typing besides peer- and self-socialization. For example, gender identity may influence children’s attention to, or acceptance of, parental or media messages about gender. These other possibilities have yet to be given much theoretical or empirical attention, however. Below we first consider how gender identity affects children’s personal and social adjustment, considering how each gender identity variable contributes individually (i.e., as a statistical main effect) as well as in interaction with other variables to influence adjustment outcomes. We then consider how gender identity affects children’s gender-typed attributes. As we noted, some gender-typed attributes are also indexes of adjustment, and our discussion at times reflects this overlap. Influences of Gender Identity on Adjustment Gender contentedness. As expected, gender contentedness often is associated with positive outcomes for children of both genders, concurrently and longitudinally. These include greater selfesteem, higher self-perceived peer social competence as well as actual acceptance by peers, increased felt same-gender typicality, International Journal of Behavioral Development 43(4) healthier attachments to parents and close friends, less depression, fewer peer-reported internalizing problems (e.g., social withdrawal, sadness, anxiety), and less victimization by peers (Carver et al., 2003; Cooper et al., 2013; Egan & Perry, 2001; Menon, 2011, 2017; Pauletti et al., 2014, 2016; Yunger et al., 2004). However, gender contentedness sometimes also predicts narcissism, for children of both sexes (Pauletti et al., 2014); this suggests that the generally positive self-concept of highly gender-content children may have an egotistical element. Some correlates of gender contentedness are more genderspecific. For girls, gender contentedness tends to be associated with communal behavior, self-perceived physical attractiveness, low externalizing behavior, and low avoidant attachment to parents. For boys, it more often is associated with agentic behavior, low communal behavior, intergroup bias, and absence of anxious, preoccupied relationships with parents and close friends (Carver et al., 2003; Cooper et al., 2013; Egan & Perry, 2001; Pauletti et al., 2016). As indicated, the adjustment consequences of gender contentedness sometimes depend on other cognitive and behavioral attributes that children may possess. The findings provide evidence for both the stereotype emulation and self-discrepancy interaction hypotheses. (All subsequent statements indicating that two variable interact, or combine, to influence an outcome, are supported by significant interaction terms, with follow-up tests showing that the effect of one predictor hinges on level of the other in the way described.) Consistent with the stereotype emulation hypothesis, if highly gender-content children believe that an antisocial or other selfpromoting attribute (e.g., dominance) is more common or desirable for their gender than for the other, they tend to say that they too possess the attribute (Menon, 2006; Perry et al., 2012). In a similar vein, if they believe that their gender is the more proficient at an academic subject (e.g., reading, math, science, language, or art), they tend to perceive their own competence at the subject to be high as well. Although these outcomes may enhance children’s selfesteem, they may contribute to the narcissism of some highgender-content children. High gender contentedness does not appear to spur children’s emulation of stereotypes that prescribe less ego-boosting traits for their gender (e.g., prosocial behavior). Gender contentedness also interacts with traditional sexist stereotypes that grant males power and privilege over females. According to the stereotype emulation hypothesis, high gender contentedness should lead sexist boys to develop dominance and lead sexist girls to become submissive. However, highly gender-content children of both sexes who endorse sexist stereotypes become more aggressive and narcissistic over time (Pauletti et al., 2014). Thus, even highly gender-content girls are somehow empowered by sexist beliefs that relegate them to an inferior, passive status. Perhaps gender contentedness causes sexist girls to see benefits for themselves in sexist roles (e.g., to see males as protectors and providers), leading to ego-enhancing outcomes. Gender contentedness also interacts with other variables in ways consistent with the self-discrepancy hypothesis. Children of both sexes who are dissatisfied with their gender yet feel strong pressure for gender conformity (or possess other gender prescriptions, including sexist stereotypes prescribing male dominance over females) experience depression, peer-reported internalizing difficulties, and related social problems (e.g., peer victimization; Egan & Perry, 2001; Perry et al., 2012). Thus, endorsement of strong gender-differentiating stereotypes constitute gender “oughts” that create a painful self-discrepancy for children who are unhappy with Perry et al. their gender. The problems of children with this self-discrepancy are not limited to internalizing symptoms, however, because these children also tend to be aggressive. When people possess an “ought self-discrepancy” (i.e., feel they should be something they are not), they tend to experience agitated distress when their selfdiscrepancy is made salient; this leads to problems of selfregulation (Higgins, 1987) and may account for their aggression. Consistent with this possibility, children with a gender selfdiscrepancy tend to direct their aggression toward gendernonconforming peers (i.e., peers who prefer other-gender activities and playmates); perhaps such peers pique their gender selfdiscrepancy (Pauletti et al., 2014). Gender discontent also causes problems for children who are overtly gender-nonconforming (as perceived by peers). Gendernonconforming boys who are unhappy with their gender suffer a loss of self-esteem over time, perhaps fearing that their gender dissatisfaction and cross-gender inclinations will endure, prove difficult to regulate, and lead to other later difficulties. Gendernonconforming girls who are gender-discontent also suffer distress. Most gender-nonconforming girls are popular, athletic, and confident, but those who are gender-discontent are vulnerable to depression (Pauletti et al., 2014). In summary, although high gender contentedness often benefits children, it can combine with gender prescriptions to create selfserving, egotistical outcomes. Although low gender contentedness often disadvantages children, it does not inevitably do so; it presents problems for children mainly when combined with gender mandates, leading to a painful self-discrepancy. These interaction effects support the stereotype emulation and gender selfdiscrepancy hypotheses. Felt pressure for gender differentiation. As Bem (1981, 1993) and others (e.g., Bussey & Bandura, 1999; Egan & Perry, 2001) predicted, children who feel pressure to avoid other-sex behavior often develop adjustment problems, concurrently and longitudinally. These consequences tend to be gender-specific. For girls, felt pressure for gender conformity predicts depression, low selfesteem, peer-reported internalizing difficulties, peer rejection, peer victimization (especially by boys), anxious attachments to parents and friends, low self-efficacy for sports (and other agentic behaviors), and sexist beliefs disparaging females. Boys who feel strong pressure for gender conformity are prone to narcissism, intergroup bias, aggression, low prosocial behavior, and sometimes depression and internalizing symptoms (Carver et al., 2003; Egan & Perry, 2001; Pauletti et al., 2014; Perry et al., 2012; Yunger et al., 2004). However, in one study boys with high felt pressure were high achievers in math (Perry & Sharif, 2002). Also, felt pressure is sometimes associated with reduced internalizing symptoms for boys; however, this may be limited to cultures where gender norms advantage males (e.g., Hispanic culture, India; Corby et al., 2007; Menon and Hannah-Fisher, in press). High felt pressure for gender conformity also combines with other factors to cause difficulties for children (or their interaction partners). These interactions provide evidence for the stereotype emulation and self-discrepancy hypotheses. Similar to high gender contentedness, high felt pressure for gender conformity encourages emulation of stereotypes that prescribe antisocial or self-serving behavior for one’s gender. If children believe it is more desirable or more common for persons of their gender to be popular, dominant, or aggressive, then felt pressure encourages self- as well as peer-perceived possession of the attribute (Perry et al., 2012). Felt pressure tends not to encourage 297 emulation of stereotypes that prescribe healthier behaviors for one’s gender (in this sense, it functions similarly to high gender contentedness). Further, felt pressure spurs children of both sexes to emulate traditional sexist stereotypes that accord males power over females. Boys who harbor such stereotypes and feel pressure for gender conformity tend to develop externalizing problems—dominance and aggression, especially toward girls. However, girls who feel pressure and believe they should defer to males develop an alarming array of internalizing problems and related peer difficulties—low self-esteem, low self-efficacy for sports, low academic self-efficacy, low body satisfaction, and peer-perceived submissiveness, helplessness, anxiety, social withdrawal, and victimization by peers. Thus, felt pressure for gender conformity causes straightforward emulation of sexist, male-advantaging stereotypes for girls as well as boys (in this respect, it functions differently from high gender contentedness; Pauletti et al., 2014; Perry et al., 2012). High felt pressure for gender conformity combines with selfand peer-perceived incompatibility with one’s gender to create painful gender self-discrepancies. We saw that felt pressure for gender conformity creates a self-discrepancy if children are discontent with their gender, but it also does so if children feel different from same-gender peers, if they feel similar to other-gender peers, or if they are perceived by peers as gender-nonconforming. Thus, there are several ways in which high felt pressure for gender conformity can pathologize children’s uncertainty over their fit with their gender. In each case, girls as well as boys risk serious personal and social difficulties—depression, low self-esteem, low body satisfaction, low academic self-efficacy, peer-reported internalizing symptoms, peer rejection and victimization, and aggression (especially toward girls and gender-atypical peers; Aults, 2016; Carver et al., 2003; Cooper, 2014; Pauletti et al., 2014; Perry et al., 2012; Yunger et al., 2003, 2004). In summary, strong felt pressure for gender conformity combines with other risk factors to affect children adversely. It encourages emulation of problematic gender stereotypes and causes considerable difficulties for children who question their fit with their gender. These findings support the stereotype emulation and self-discrepancy hypotheses. Intergroup bias. In-group favoritism is sometimes a strategy for maintaining self-esteem (Taylor & Brown, 1988), but it can also undermine cooperative, respectful interactions with other-gender peers and ultimately lead to interpersonal problems, rejection by peers of both genders, and low self-esteem (Bigler, Jones, & Lobliner, 1997; Egan & Perry, 2001; Kornienko et al., 2016; Powlishta, 1995). It is associated with endorsement of sexist stereotypes, for children of both sexes. A few sex differences in the correlates of in-group favoritism are noteworthy. Girls with strong intergroup bias are perceived by peers to be submissive, rarely aggressive toward other girls, and depressed; they have low self-worth and report low self-efficacy for sports, popularity, and physical attractiveness. Boys with strong ingroup favoritism tend to be narcissistic (despite their low selfesteem), report that it is easy to display dominance and inhibit tenderness, and deny depressive symptoms; they are not well liked by peers but, surprisingly, are nonetheless viewed as popular (Pauletti et al., 2014). Interactions of intergroup bias with other variables have not been extensively explored. However, in-group favoritism encourages narcissism among children of either sex who believe that dominance is desirable for their gender or who espouse sexist beliefs advantaging males over females (Pauletti et al., 2014). By 298 encouraging narcissism among sexist girls as well as boys, intergroup bias functions more like gender contentedness than like felt pressure for gender conformity. Felt same-gender typicality. As expected, children who perceive themselves as similar to same-gender peers report higher self-esteem, lower depression, higher self-perceived peer social competence, and more secure relationships with close friends (less preoccupied or avoidant); they also are viewed by peers (of both sexes) as likable, prosocial, lacking internalizing difficulties, and rarely victimized (Bos & Sandfort, 2010; Carver et al., 2003; Corby et al., 2007; Drury, Bukowski, Velasquez, & Stella-Lopez, 2013; Egan & Perry, 2001; Jewell & Brown, 2014; Martin et al., 2017; Menon, 2011; Pauletti et al., 2014, 2017; Smith & Leaper, 2006; Young & Sweeting, 2004; Yu, Winter, & Xie, 2010; Zosuls, Andrews, Martin, England, & Field, 2016). The advantages of felt same-gender typicality remain evident even when multiple measures of children’s gender typing (e.g., gender-typical personality traits, activity preferences, interaction partners, sexual identity) are statistically controlled, indicating that children’s omnibus summary appraisals of gender typicality are important beyond influences of specific aspects of gender typing (Egan & Perry, 2001). The benefits of felt same-gender typicality for self-esteem are evident not only for North American children but also for children in Britain, China, Colombia, India, and the Netherlands. Rarely is felt samegender typicality associated with a negative outcome, though occasionally it is associated with aggression, for children of both sexes (Pauletti et al., 2014; Yunger et al., 2004). Unlike other gender identity variables, there are no consistent gender differences in the adjustment correlates of felt same-gender typicality. Felt same-gender typicality also interacts with other variables to affect children’s well-being. In contrast to high levels of betweengender forms of gender identity, there is slim evidence that high felt same-gender typicality fosters emulation of harmful gender stereotypes (or even of more benign gender stereotypes). This is somewhat surprising given the theoretical emphasis on perceived similarity to a gender as a motivator of stereotype emulation (e.g., Martin, 2000; Tobin et al., 2010). However, felt samegender typicality combines with other variables in ways consistent with three other interaction hypotheses—the gender selfdiscrepancy, protective function, and androgyny hypotheses. Consistent with the self-discrepancy hypothesis, children who feel different from others of their gender tend to develop internalizing (and sometimes externalizing) problems if they also feel strong pressure for gender conformity (e.g., Carver et al., 2003). Children who appraise themselves as gender atypical but feel little pressure for conformity are relatively free of such problems. Thus, despite the benefits of high felt same-gender typicality, low felt typicality is not inevitably harmful. In accord with the protective function hypothesis, high felt same-gender typicality buffers children from the negative consequences of potentially harmful social and cognitive risk factors. Several examples are noteworthy. First, high felt same-gender typicality protects victimized children (and adults) from the internalizing problems and low self-esteem that typically result from victimization (Aults, 2016; Pauletti et al., 2014; Szucs, Schindler, Reinhard, & Stahberg, 2014; Yunger et al., 2003). Second, high felt same-gender typicality minimizes the distress of children who perceive themselves as deficient in some important aspect of social or personal functioning: children who lack self-efficacy for academics, sports, physical attractiveness, or making friends are unlikely to become depressed or to lose self-esteem if they feel International Journal of Behavioral Development 43(4) similar rather than dissimilar to same-gender peers (Pauletti et al., 2014; Perry et al., 2012). Third, high felt same-gender typicality protects children who believe they possess demonstration attributes (attributes that garner attention and admiration from peers, such as physical attractiveness or athleticism) from becoming narcissistic: children who acknowledge such qualities develop narcissistic tendencies if they feel dissimilar to same-gender peers but not if they feel similar to them (Perry et al., 2012). What accounts for these diverse protective effects of felt samegender typicality? Perhaps high felt same-gender typicality reflects a confident sense that one’s same-gender peers (at least a subset of them) are available for fun, intimacy, companionship, affection, support, protection, and other crucial affordances of the peer group. Children who enjoy this sense of security may minimize the negative implications of peer victimization, peer rejection, or a selfperceived inadequacy, and they may have little need to derive narcissistic motivation from self-perception of traits that garner peer admiration. Finally, there is evidence for Bem’s (1981, 1993) androgyny hypothesis. Consistent with Bem’s thesis, if children perceive themselves as similar only to their own gender, they tend to display signs of the gender-polarizing cognitive schema she described. That is, compared to children who view themselves as similar to both genders (i.e., children with more androgynous identity), children who see themselves as similar only to their own gender report greater pressure for gender differentiation, intergroup bias, and sexist beliefs, and they have less expectation of friendly interaction with other-gender peers; they do not, however, have lower selfesteem (Martin et al., 2017; Pauletti et al., 2017). Felt other-gender typicality. Little is known about the consequences of felt other-gender typicality. However, when considered as an independent predictor of adjustment, felt similarity to othergender peers is associated with low self-esteem (Pauletti et al., 2017), victimization by peers (Zosuls et al., 2016), and, for girls, agentic behavior (Menon, 2006). Relatively little research examines interactions of felt othergender typicality with other variables. Nonetheless, consistent with the androgyny hypothesis, it is when children feel similar only to the other gender that they suffer low self-esteem and internalizing problems: if they feel similar to both genders, they tend not to have these problems (Martin et al., 2017; Pauletti et al., 2017). Thus, androgyny offers advantages over both same-gender-only identity and other-gender-only identity. Its advantage over the former is less gender-polarizing cognition (see above); its advantage over the latter is fewer internalizing difficulties. We should caution that children identified as androgynous (i.e., children who score higher than same-sex peers on both felt samegender typicality and felt other-gender typicality) rarely score as high on felt other-gender typicality as on felt same-gender typicality in absolute terms (Martin et al., 2017; Pauletti et al., 2017). Thus, it is probably accurate to characterize these children as having a primary same-gender identity coupled with a secondary other-gender one. Indeed, other-gender qualities (e.g., cross-sex friendships) and identity may benefit children primarily when auxiliary to a strong sense of same-gender typicality (Bukowski, Panarello, & Santo, 2017; Kovacs, Parker, & Hoffman, 1996; Martin et al., 2017; Ullian, 1976). Moreover, even though felt other-gender typicality may protect children who feel same-gender typical from developing genderpolarizing cognition, it does not offer the same range of protective functions as does felt same-gender typicality. For example, high felt Perry et al. other-gender typicality does not protect children from stressors that cause internalizing problems (e.g., victimization by peers; Martin et al., 2017; Pauletti et al., 2017). High felt other-gender typicality can also figure in painful gender self-discrepancies. If high felt other-gender typicality occurs in conjunction with gender “oughts” (e.g., felt pressure for samegender conformity, prescriptive gender stereotypes), children tend to experience depression, body dissatisfaction, low self-esteem, and low academic self-efficacy (Pauletti et al., 2017). Thus, felt other-gender typicality and felt same-gender typicality do not offer children equivalent adjustment benefits. Instead, the consequences of felt other-gender typicality hinge on children’s level of felt same-gender typicality. If children feel same-gender–typical, felt other-gender typicality offers the benefit of reduced genderpolarizing cognition; if children do not feel same-gender–typical, felt other-gender typicality exposes them to a number of risks. Influences of Gender Identity on Gender Typing We turn now to evidence relevant to the peer-socialization and selfsocialization pathways to children’s adoption of gender-typed attributes. We consider each pathway in turn. Peer-socialization pathway. Scant attention has been paid to gender identity’s influence on the sex(s) of children’s interaction partners or children’s susceptibility to influence by peers of each sex. Children do choose same-sex friends whose level of felt samegender typicality or gender contentedness resembles their own, and over time they increasingly resemble their friends’ intergroup bias and felt pressure for gender conformity (Kornienko et al., 2016). These data are consistent with the peer-socialization pathway, but many other questions about the role of gender identity in peer socialization remain. Do the dimensions of gender identity act individually, or possibly in combination, to influence the gender mix of children’s peer associates? With whom do children suffering a gender self-discrepancy interact? Perhaps they have difficulty finding friends, owing to their conflicted self-concept and off-putting mix of depression and aggression. Does gender identity influence children’s attention to, or imitation of, peers of a particular gender? Do these various peer processes mediate the influences of gender identity on children’s gender typing (and perhaps their adjustment)? Given the importance of peers in the socialization of gender (Harris, 1995; Martin et al., 2013; Ruble et al., 2006), such questions are important. Self-socialization pathway. We previously summarized interactive influences of gender identity and gender stereotypes on children’s adjustment. Many, but not all, of these interactions were consistent with the stereotype emulation hypothesis of the selfsocialization pathway to gender typing. For example, betweengender forms of gender identity often encourage children to adopt self-promoting attributes they believe are more typical of, or more desirable for, their own gender than for the other. Here we examine the question of whether gender identity motivates children to adopt gender-stereotyped attributes that are less obviously related to adjustment (e.g., recreational interests). Further, instead of examining whether gender identity influences children’s emulation of individual attributes, we see whether gender identity predicts an index of stereotype emulation aggregated across multiple attributes. This allows us to see if a gender identity variable serves as a dispositional motivator of children’s adoption of gender-typed behaviors. 299 To address this latter issue, we reconsider the Menon (2006) study described earlier (when discussing the development of felt same-gender typicality). Menon’s study included measures not only of five gender identity variables (gender contentedness, felt pressure for gender conformity, intergroup bias, felt same-gender typicality, and felt other-gender typicality) but also of children’s stereotype ratings and self-perceptions of 62 school-based behaviors (e.g., making a new boy at school feel welcome by talking with him at lunch, acting tough on the inside when feeling afraid on the inside, learning to play a musical instrument). All behaviors were ones for which there was considerable variability among children of each gender in both stereotype ratings and self-perceptions. An aggregated stereotype emulation score was computed for each child (see earlier), and the gender identity variables were treated as predictors. This study was not longitudinal, however, so conclusions must be tentative. Felt pressure for gender conformity and intergroup bias were negligibly related to stereotype emulation. The other gender identity variables were all individually predictive, with gender contentedness showing the strongest effect, felt same-gender typicality the weakest, and felt other-gender typicality falling in-between. However, when these three gender identity variables were entered together, only the effect of gender contentedness remained significant. These results are surprising because gender contentedness has received less theoretical attention as a motivator of gender typing than two other gender identity variables—felt same-gender typicality and felt pressure for gender conformity. However, other data support the possibility that gender contentedness plays a greater role in children’s gender typing than previously thought. In one study (Pauletti et al., 2014), gender contentedness predicted decreased overt gender nonconformity (peer-reported) over time; neither felt pressure for gender conformity nor felt same-gender typicality did so. Gender contentedness also predicted increased felt same-gender typicality (but the reverse was not true). Further analysis of Menon’s (2006) data suggests how gender contentedness might contribute to gender self-socialization. Gender contentedness was correlated with felt other-gender typicality more strongly ( 0.61) than with felt same-gender typicality (0.34). This suggests that gender contentedness may contribute to gender selfsocialization mainly by influencing how children deal with behaviors they encode as appropriate for the other gender. That is, high gender contentedness may deter children from other-gender options, and low gender contentedness may attract children to them. Other data accord with this possibility. For children of both genders, gender contentedness correlates negatively with other-gender attributes (e.g., agentic behavior for girls, communal behavior for boys) more strongly than it correlates positively with same-gender attributes (Carver et al., 2003; Egan & Perry, 2001; Pauletti et al., 2014). Clinicians too are sometimes struck by the degree to which gender dysphoric children strive to adopt the conspicuous badges of the other gender, as if to affirm their preferred other-gender identity and display it to others (B. Khorashad, personal communication, 2017). Although gender contentedness may especially affect how children negotiate cross-gender options, it would be incorrect to suggest that this is the sole way it operates. Recall that children who are highly satisfied with their gender adopt self-promoting attributes they regard as desirable for their gender. Nonetheless, these findings suggest that neither felt samegender typicality nor felt pressure for gender conformity is the 300 broad dispositional motivator of stereotype emulation suggested by prevailing theories. A few comments about each of these other forms of gender identity are in order. Overall, research suggests that felt same-gender typicality is more likely to be the result of children’s gender typing—an afterthe-fact cognitive summary of it—than a cause of it. It rarely predicts children’s overt or self-perceived gendered attributes but is often predicted by such attributes. Even though felt same-gender typicality may not act proactively as a dispositional motivator of gender typing, it may affect how children react when their sense of gender typicality is threatened. Spence (1993; Spence & Hall, 1996) suggested that threats to gender identity normatively elicit anxiety and spur people to display a compensatory salient same-gender attribute (e.g., men are more likely than women to react to gender threats with aggression; Vandello & Bosson, 2013). However, a person’s characteristic level of felt same-gender typicality may influence how the person copes with downward fluctuations in felt typicality. In particular, if high trait felt same-gender typicality reflects felt security among one’s same-gender collective, it may protect against, rather than spur, compensatory reactions. Felt pressure for gender conformity also may not be a broad dispositional motivator of gender typing, but its potential to spur emulation of stereotypes that prescribe antisocial or debilitating attributes for one’s gender (e.g., sexist stereotypes) is important. Felt pressure for gender conformity may also affect how people react to gender threats (e.g., cause them to experience gender threats as urgently in need of repair). Perhaps persons who harbor a gender self-discrepancy are the most likely to react in a dysregulated way (e.g., aggressively). Comment on Consequences of Gender Identity Each gender identity variable affects children in some unique way, underscoring the value of a multidimensional perspective on gender identity. Each also interacts with one or more other variables, such as another gender identity variable or a prescriptive gender stereotype, to predict adjustment or gender typing. Several general conclusions are suggested. Between-gender forms of gender identity—gender contentedness, felt pressure for gender conformity, intergroup bias—encourage children of both sexes to emulate stereotypes that prescribe antisocial, selfish behaviors for their gender. They also cause problems for children who espouse traditional sexist stereotypes granting males power and privilege over females. Felt same-gender typicality buffers children from harmful effects of personal and social risk factors. However, it is associated with gender-polarizing cognition (e.g., felt pressure for gender differentiation, sexist stereotypes) unless children see themselves as at least somewhat similar to the other gender as well. Felt other-gender typicality is associated with distress if children feel different from their own gender. Children who feel other-gender–typical ordinarily possess little gender-polarizing cognition, but if they do possess such cognition, they tend to experience a highly distressing gender self-discrepancy. Indeed, children who have any of several reasons to question their fit with their gender—who feel dissatisfied with their own gender, who feel different from same-gender peers, who feel similar to the other gender, or who are overtly gender nonconforming—tend to experience adjustment difficulties (e.g., depression, International Journal of Behavioral Development 43(4) low self-esteem) mainly to the extent that they feel pressure for gender conformity (or other gender-differentiating cognition). This is important because it underscores the severe harm that gender self-discrepancies can cause children, indicates that children who question their gender fit are not inevitably handicapped, and carries implications for parents, teachers, and other socializing agents. Gender contentedness may be a stronger dispositional motivator of gender typing than other forms of gender identity. Further, it may be low-gender–content children who drive this self-socialization effect. That is, gender dysphoria may spur children’s attraction to other-gender peers, interests, and behaviors. Additional potential consequences of gender identity are in need of study. These include social information processing variables (e.g., attention, causal attribution, memory, classification, stereotyping, response search, response evaluation), reactions to gender threat, and a broader range of gender-typed attributes than typically studied (e.g., sexual orientation, nonverbal gender-typed stylistic attributes such as mannerisms and vocal patterns). Conclusions It is remarkable that ordinary school children are able to introspect about themselves in relation to gender so thoughtfully and on so many different dimensions. Their willingness to share their intimate thoughts and feelings on this topic has allowed us to develop a rich understanding of the ways they think about themselves in relation to gender, how these ways develop, and how they affect their welfare and behavior. Here we offer a few final comments and suggestions for future research. The use of paper-and-pencil self-report scales to assess multiple dimensions of gender identity has much to recommend it, but such scales only capture consciously accessible (explicit) aspects of gender identity and ignore potentially influential unconscious (implicit) aspects. Reaction time tasks are one window into unconscious processes (e.g., Cvencek et al., 2011), but narrative assessments (e.g., that use the coherence of children’s narrative responses to gender dilemmas to infer unconscious insecurity) may also be useful. It would be interesting to see whether children whose scores on self-report measures indicate internal conflict (e.g., children with a gender self-discrepancy) exhibit more incoherence on narratives assessments. Also, disparities between implicit and explicit forms of gender identity may prove informative. It is clear that a child’s pattern of gender identity is often more influential than a child’s score on any single gender identity variable at predicting adjustment. Cluster analysis may be useful for identifying more complex patterns of gender identity that predict adjustment (e.g., Martin et al., 2017), and once these patterns are identified, it would be worth investigating their determinants. For certain purposes, cluster analyses might include not only the gender identity variables but also one or more other gender phenomena, such as children’s expectations for a heterosexual future, their overt gender nonconformity, or a biological variable such as sex hormones. This would permit determining, for example, the pattern(s) of gender identity that characterize children who question their heterosexuality. Once such clusters are identified, their determinants and adjustment consequences could be studied. It is known that many other gender phenomena are correlated with gender identity (Carver et al., 2004; Ruble et al., 2006), and such an approach may help identify roots of their co-variation. Perry et al. The implications of our review for practical application are limited but warrant comment. A fairly straightforward recommendation is that adults—parents, teachers, counselors—should strive to minimize children’s development of felt pressure for gender conformity and negative attitudes toward the other gender. Adults should be mindful that some children may suffer gender-related confusion or insecurity, perhaps experiencing a gender selfdiscrepancy but unable to articulate it. Adults may wish to encourage children to investigate other-gender as well as same-gender options of interest to them, but behavioral interventions designed to foster felt same-gender typicality or androgyny are questionable. Given the diversity among children in temperaments, interests, abilities, opportunities, and so on, a “one size fits all” approach to gender identity is unlikely to be realistic or desirable. Allowing children to pursue their own interests—even if heavily gendertyped in one direction—is probably more justifiable, as long as children learn to respect each gender collective as well as the diversity within each collective in members’ gender-typed characteristics. It may fall to children with atypical gender identity— perhaps those who question their gender fit and are frustrated by society’s gender rules—to perceive the inequality in gender divisions and to be vanguards of social change. Affect may play a bigger role in the development and operation of gender identity than previously expected. Insecurity of multiple origins—insecure relationships with parents and friends, victimization or rejection by peers—fosters between-gender forms of gender identity (and erodes felt same-gender typicality). This suggests that insecure children latch onto gender roles and rules to make their world feel safer and more predictable. Whether this affective, defensive route is a stronger influence on gender identity than the messages children receive about gender from their social environments is unknown. The affective aspects of gender identity may also be responsible for its impact on children’s gender typing and well-being. Certain forms of gender identity, especially intergroup bias and gender contentedness, are inherently affective and may have a direct influence on children’s liking for peers and activities of one gender and aversion to those of the other. Felt pressure for gender conformity may also act via affect, given that it is a fearbased motive to avoid other-gender activities. Our review is based mainly on findings with predominantly White samples of ordinary school children attending schools in the United States and United Kingdom. Gender identity does not necessarily function in the same way across cultures or subcultures, however, and cross-cultural variation in the meaning, development, and outcomes of gender identity is in need of study (Corby et al., 2007). Until such data are available, it is probably prudent to consider many of the conclusions we have offered as culture-specific rather than universal.
