Abstract
The sexual harassment of girls and women is a common occurrence that begins in early adolescence and continues into adulthood. Not only is experiencing sexual harassment common, but it is also widely accepted and tolerated. In the current article, we use the bioecological theory of sexual harassment of girls to explain why this may be. Specifically, we discuss that the perpetration and tolerance of sexual harassment is built on a foundation of gendered socialization, media consumption, peer interactions, and permissive school environments that encourages passivity and objectification in girls and aggressiveness and dominance in boys. We outline how this process begins in infancy and continues throughout development, ultimately fostering an environment in which the sexual harassment of girls and women flourishes. Important implications for preventing sexual harassment are also discussed.
As the public discourse in recent years has shown (e.g., #MeToo movement), sexual harassment and assault against women and girls 1 is prevalent. Sexual harassment, broadly defined here as unwanted sexual attention (McMaster et al., 2002), includes undesired sexual touching or comments, comments or rating of one’s body parts, and unwanted sexual texts. By the end of high school, 90% of adolescent girls have experienced sexual harassment at least once (e.g., Leaper & Brown, 2008). By the end of college, one in five women have been the victim of sexual assault (e.g., Muehlenhard et al., 2017). Sexual harassment among adolescents is so common that almost all students (96%) in a sample of middle school students reported witnessing sexual harassment at school (Lichty & Campbell, 2012), and the most frequent sexual harassment involves boys sexually harassing girls (Jewell et al., 2015).
Although boys may be unaware that their sexual attention or behavior is unwanted and may be unaware of the consequences of sexual harassment for girls, sexual harassment is often extremely damaging to girls’ social, emotional, and academic outcomes (Hand & Sanchez, 2000), leading to negative body appraisals, depression, disordered eating, substance abuse, externalizing behaviors, and suicidal thoughts (Goldstein et al., 2007). Despite recent public attention focused on the sexual harassment of women and the long-term negative consequences of sexual harassment on physical, mental, and emotional health, there is still considerable cultural acceptance of sexual harassment and assault targeting girls and women. For example, many girls feel that reporting sexual harassment at school is useless because teachers do nothing in response to these reports (Brown et al., 2022). A majority of girls also disclosed that they do not report sexual harassment because they are worried that people would not like them if they did (Plan International & PerryUndem, 2018).
In the current article, we will explore some of the reasons why the sexual harassment of girls and women is so common and culturally accepted (most of the research on these topics has been conducted in the United States, Canada, the United Kingdom, and Italy, and thus further generalizations should be limited). Specifically, we point to our bioecological theory of sexual harassment of girls (Brown et al., 2020) and argue that the high rates of perpetration and tolerance of sexual harassment (and at times, sexual assault) against girls and women is, in part, an expected developmental consequence of sociocultural contexts that begin in infancy (see Fig. 1). Elsewhere (Brown et al., 2020), we elaborate on how the proximal contexts of parents, peers, and schools, as well as the distal context of media, contribute to this. Here, we focus on how the foundation of the sexual harassment of girls by boys is laid and reinforced at every stage of child and adolescent development, specifically infancy and early childhood (birth to age 5), middle childhood (age 6 to 11), and adolescence (age 12 to 18).

Developmental trajectory of the bioecological theory of sexual harassment.
Infancy and Early Childhood
In infancy and early childhood, children are particularly influenced by parental socialization and broad cultural norms that shape different trajectories for cisgender boys and girls.
Focus on binary gender/sex categories
From birth, parents and society commonly focus on the physical and psychological salience of their children’s gender/sex (with an overemphasis on the binary gender/sex identified at birth; Hyde et al., 2019). Specifically, parents often amplify the salience of a binary gender/sex by assigning gendered names, hairstyles, clothing, bedroom colors, decorations, and toy purchases (Leaper, 2015). In addition, children regularly hear gender/sex categories emphasized in gendered labeling of individuals and groups (“What a smart girl you are!” “Those two boys are playing ball”).
When categories are made physically and psychologically salient in this way, children are more likely to become attuned to the category and subsequently develop stereotypes about that category (for empirical evidence of this, see developmental intergroup theory; Bigler & Liben, 2007). Given how much gender/sex is used as a functional category, it is not surprising that children are very attentive to messages that gender/sex is important. By preschool, most children can identify their own gender/sex and attend to, seek out, and better remember information relating to their own gender/sex (Martin & Ruble, 2004). Children subsequently develop strong stereotypes about those categories. By preschool, many children endorse the stereotypes that girls are more likely than boys to be fearful, sad, and happy, and boys are more likely than girls to be angry (e.g., Parmley & Cunningham, 2008).
Parent socialization of different emotions
Not only are children attending to gender/sex differences, but parents also play a critical role in socializing boys’ and girls’ emotional and behavioral expression, particularly in ways that lay the groundwork for boys engaging in harassing and aggressive behavior toward girls and for girls’ discomfort at confronting that behavior. Previous research suggests that parents typically pay more attention to their daughters’ submissive emotions (e.g., sadness, anxiety) relative to their sons’ feelings, and this parental attention predicts girls’ greater expression of submissive emotions at school age (e.g., Chaplin et al., 2005). In contrast, parents are more likely to discuss, tolerate, and model assertiveness, anger, and aggression with their sons relative to their daughters (e.g., Letendre, 2007). Boys, in turn, tend to experience fewer negative consequences in response to their anger than girls do (Eisenberg et al., 1998). A possible relevant consequence of these two socialization trends (girls’ submission vs. boys’ assertiveness) is that, by early childhood, girls are more likely than boys to be uncomfortable confronting a peer, and they are especially uncomfortable confronting a male peer (for a review, see Green & Rechis, 2006).
Focus on appearance
Not only are girls, on average, socialized to be submissive, but they are also encouraged to focus specifically on their appearance. Between the ages of 3 and 6, more than half of girls pass through a “pink frilly dress” phase (Halim et al., 2014) marked by a rigid preference for a highly feminine appearance at the expense of active movement. They also express appearance-related concerns, such as asking for feedback or saying negative statements about their appearance (e.g., “Do I look pretty?” “I don’t like my hair/nose/bottom”; Tiggemann & Slater, 2014).
Conclusion
Beginning in infancy and increasing in early childhood, girls are often socialized by their parents and society to be affiliative, passive, and appearance focused; meanwhile, boys are encouraged to be assertive, and boys’ aggression is often tolerated or excused. This focus on girls’ appearance (coupled with submissive emotions) and boys’ aggression are the early developing patterns that play a key role in later tolerance of sexual harassment.
Middle and Late Childhood
As children enter school in middle childhood, peers and peer norms take on increasing importance in shaping children’s attitudes and behaviors.
Peer segregation by gender/sex
By the time children enter middle childhood, they tend to play and congregate in groups of same-gender/sex peers; boys tend to play in all-boy peer groups, whereas girls tend to play in smaller all-girl peer groups (e.g., Martin et al., 2013). High levels of peer segregation have two critical consequences. First, as children spend more and more of their playtime interacting with same-gender/sex peers, they increasingly socialize themselves in gender-stereotypical ways, exacerbating previously smaller gender/sex differences (Martin & Fabes, 2001). Same-gender/sex peer groups have been shown to be particularly influential in the development of aggression and delinquent behavior among boys (Rohlf et al., 2016). In other words, as boys move through childhood, they tend to play primarily with other boys and become similarly aggressive. Second, because boys and girls are segregated, they are less likely to develop close friendships with one another, and they may fail to develop positive interaction patterns prior to adolescence (Martin & Fabes, 2001).
Pressure to conform to gender norms
Not only are children largely interacting in gender/sex-segregated peer groups, but they are also increasingly focused on conforming to gender norms for appearance and behavior. Conforming to gender norms has important implications for peer acceptance and social status because gender-typical children are more likely to be popular and less likely to be teased, rejected, and harassed than their less gender-typical peers (Jewell & Brown, 2014).
Being accepted by the peer group and being popular require different qualities for boys and girls. For girls, beginning in middle childhood, popularity equates with being nice; being pretty; and with age, being sexualized (e.g., Stone et al., 2015). There is a shift from valuing an attractive appearance (in which being well-groomed is the key criterion) to valuing a sexualized appearance. Across multiple studies using different stimuli, both boys and girls perceived sexualized girls (e.g., wearing a miniskirt, midriff shirt, and makeup) to be more popular and pretty than an equally well-groomed nonsexualized girl (e.g., wearing jeans and a blouse; Stone et al., 2015). By early adolescence, many girls aspire to emulate images of sexualized girls as a means of matching the cultural norm (McKenney & Bigler, 2016).
For boys, being accepted by the peer group and being popular means being dominant, sexually assertive, and aggressive. For example, popular boys are typically expected to be focused on dating girls or being “a player” (Jewell & Brown, 2014). When boys stand up for girls who are sexually harassed, they are often subjected to homophobic harassment (Reigeluth & Addis, 2016). Boys also regularly report feeling pressure from peers to be aggressive (Plan International & PerryUndem, 2018). Gender norms are especially rigid for boys, and boys who do not embody this dominant, aggressive form of masculinity are often devalued and ridiculed (Jewell & Brown, 2014).
Stereotypical media and toys
The building expectations that girls should be sexualized and boys should be aggressive are also reinforced by children’s media and toys. Research has robustly documented the prevalence of sexualized depictions of women and girls in virtually all forms of media (e.g., Ward, 2016). In an analysis of 10 of the most popular American television shows among White and Latina girls, evidence of sexualization of female characters was found in every one (McDade-Montez et al., 2017). Additionally, one of the most common themes in popular children’s shows is boys objectifying girls on the basis of their attractiveness (Kirsch & Murnen, 2015). Although girls’ media focuses on sexualized images, media marketed to boys (including sports programming heavily consumed by boys) promotes and models aggression, violence, and antisocial behaviors (e.g., Kahlenberg & Hein, 2010). When boys with feminine qualities are shown on television, they are often the butt of a joke (Myers, 2012).
Similar patterns also appear in toys marketed to boys and girls. Specifically, research shows that toys with aggressive components, such as action figures and toy weapons, are marketed to boys, whereas toys marketed to girls focus on adult-like (typically, sexualized) beauty (such as makeup and jewelry; Auster & Mansbach, 2012). More precisely, girls’ toys are often sexualized, as many popular dolls marketed to young girls wear leather miniskirts and thigh-high boots.
Conclusion
Throughout childhood, as children begin to value being accepted by their peer group, girls are encouraged to be sexualized and “nice” to conform to peer norms. In contrast, boys are pressured to be aggressive and are typically rejected or teased by peers (and media) if they show fewer dominant behaviors. By the end of elementary school, the sexual objectification of girls and the dominant behavior of boys becomes the cultural norm.
Adolescence
As children develop into adolescents, their interactions with peers are heavily influenced by puberty and a growing interest in sexuality. For heterosexual adolescents, this means an increased desire to interact with peers of a different gender/sex; thus, the segregated peer groups of childhood evolve into more integrated groups. Although peer group composition changes in adolescence, gender norms for behavior and appearance are increasingly entrenched.
Sexualized gender stereotypes and homophobic harassment
As sexuality becomes more salient in adolescence and heteronormative sexualized media is regularly consumed, gender stereotypes become more sexualized (Stone et al., 2015; Ward, 2002). By adolescence, a majority of teens endorse sexualized gender stereotypes, in which girls are expected to prioritize their sexualized attractiveness for the attention and approval of boys, and boys are expected to be aggressively focused on the sexual pursuit of girls (Jewell et al., 2015).
Although much of the focus of sexualized gender stereotypes is centered on girls (e.g., the more girls endorse sexualized gender stereotypes, the more they downplay their academic abilities and the lower their academic motivation is; Brown, 2019), there are also implications for boys. Boys who do not conform to sexualized gender stereotypes often suffer social consequences from other boys. Namely, by not demonstrating the heteronormative sexual objectification of girls, they risk being the target of homophobic harassment, such as being called gay slurs (Reigeluth & Addis, 2016). Thus, for boys, perpetrating sexual harassment becomes a critical way to demonstrate heterosexuality, avoid homophobic bullying, and gain popularity. This appears to be effective, as social network analyses have shown that boys who perpetrate more sexual harassment are more likely to be popular than boys who perpetrate less sexual harassment (Jewell et al., 2015).
Aggressive sexuality in media
In the era of smartphones and easy access to unregulated Internet, adolescents are consuming media that is highly sexual, violent, and objectifying. Research has shown that adolescents—boys more so than girls—are first exposed to pornography (either intentionally or accidentally) between the ages of 10 and 14 (Peter & Valkenburg, 2016). Common online pornography websites are free, easily searchable, and require no age verification to open. Although the exact prevalence rates differ, it is clear that the vast majority of boys and girls have seen some form of pornography by the end of high school (Peter & Valkenburg, 2016). Not only is this media explicitly sexual, but it is also frequently violent; 88% of online pornography contains physical aggression, almost always perpetrated by men toward women (Bridges et al., 2010). Exposure to this type of sexually explicit material has been associated with the increased sexual objectification of women and greater acceptance of rape myths, in which women are blamed for being raped (for a review, see Ward, 2016).
Lack of school intervention
Despite the frequency of sexual harassment at schools, schools rarely have policies regarding sexual harassment, and teachers often ignore this behavior (Brown et al., 2022). Schools rarely cover sexual harassment, or even consent, in sexual education classes (Willis et al., 2019). When asked, teachers report that they are unclear about what constitutes sexual harassment, are unclear about their own schools’ policies, or are untrained in how to respond to sexual harassment (Edwards et al., 2020).
This lack of policies and training is apparent to adolescents. Girls report that although teachers witness sexual harassment, they rarely intervene (Brown et al., 2022). Even among the minority of students who report sexual harassment to an adult at school, more than one third indicated that either they received no protection from the teachers or the teachers treated them poorly, blaming them for the harassment (Brown et al., 2022).
Conclusion
By the end of adolescence, boys regularly sexually harass girls, in part because of a lack of previous positive interaction patterns, a desire to avoid being the target of homophobic bullying, a steady diet of sexual and violent media, and a school climate that ignores (and thus implicitly accepts) the behavior. For girls, their status is increasingly tied to sexual objectification by boys. At the same time, there are no clear sources of protection for the harassment they face.
Implications and Future Directions
Although the acceptance of sexual harassment is reinforced throughout development, the bioecological theory of sexual harassment of girls suggests important avenues for preventing sexual harassment and changing the developmental landscape that allows sexual harassment to be so prevalent (see Brown et al., 2020). Most notably, intervention efforts should occur prior to middle school, well before pubertal changes alter cross-gender/sex interaction. For example, interventions with preschoolers that focused on fostering cross-gender/sex interactions found subsequent decreases in aggression among children (Xiao et al., 2022). Research should examine how these interventions might be continued across elementary school. As children age, these interventions should account for the increasing importance of peers’ social status. For example, interventions could focus on changing the attitudes and behaviors of influential peers (e.g., popular youth), as they play a critical role in establishing and enforcing peer norms.
There are also implications for parents, who can help encourage assertive communication in girls and empathy in boys. Further, as children age, parents should monitor the sexualization in traditional and social media that children consume. For example, a recent study with adolescent girls found that a social media fast for 3 days was related to increased self-compassion, which in turn was related to lower self-objectification (Roberts et al., 2022). Lastly, schools should train teachers to recognize and intervene when they see sexual harassment and homophobic harassment, as research has shown that when teachers and staff perceived their school to be intolerant of sexual harassment, students reported less sexual harassment (Rinehart & Espelage, 2016). Future research should examine how schools can best convey anti-sexual-harassment policies to students, as current research suggests that students are unaware of the policies that do exist (Brown et al., 2022).
Importantly, the bioecological theory of sexual harassment of girls suggests that the groundwork laid throughout childhood and adolescence for the acceptance of sexual harassment may also relate to the acceptance of sexual violence against women and intimate partner violence. Therefore, understanding and disrupting this pathway is vital for creating a safer world for all.
