Sex differences in the naming of children's genitalia

Children's knowledge of human genital anatomy was examined retrospectively. Of the 223 adults who responded to a questionnaire on this subject, 39.8% of males and 29% of females learned correct anatomical names for male genitalia as children. In contrast, only 6.1% of females and 17.7% of males learned correct names for female genitalia. Most respondents learned either euphemisms or no names for female genitalia as children. Whereas male respondents acquired a complete vocabulary for male genitalia by a mean age of 11.5 years, female respondents did not complete their anatomical vocabulary for female genitalia until a mean age of 15.6 years. The importance of recognizing that children have erotic experiences and that they need a vocabulary for describing their feelings is discussed.     

Sex differences in the links between attractiveness, self-esteem and the body

Two studies were conducted to determine: if the links between the body and self-perceived attractiveness and self-esteem for men and women differ. Following evolutionary and social learning theories, affective and cognitive links were hypothesized for women's attractiveness while no links were hypothesized for men's attractiveness. Additionally, affective links were expected for women's self-esteem while no links were expected for men's self-esteem. The results obtained supported these hypotheses. Findings are discussed in terms of the societal value placed on women's attractiveness and evolutionary theory.     

Sex differences in judgments of physical attractiveness: a social relations analysis

Men and women rated the physical attractiveness of other men and women who were sitting nearby and were rated by them in return. They also provided meta-perceptions of how they thought those others rated them. Attractiveness ratings were partly a function of both the target being rated and the perceiver providing the ratings regardless of the sex of the perceiver or target, but the highest levels of consensus occurred when men judged the attractiveness of women and the highest levels of idiosyncrasy occurred when men rated other men. Meta-perceptions were also idiosyncratic; some believed that they were consistently considered attractive, whereas others thought they were seen as unattractive. People were aware of what others thought of them and, in particular, women's meta-perceptions were highly related to men's judgments of them. People agree about others' attractiveness, and those who are attractive to others know they are pretty or handsome.     

Reacting to reactance: An Interpersonal interpretation of the need for freedom

This study was designed to investigate the conditions under which the negative consequences of social influence attempts can be mitigated by freedom-affirming interventions. Eighty-eight high school girls received an influence message, presumably written by a co-worker, containing either a threat or a promise. In addition, subjects were or were not given a choice option as to mode of compliance, if they chose to comply with the message. In half the cases, the Interpersonal condition, subjects received their choice/no choice option from their co-worker; in the other half of the cases, the Noninterpersonal condition, subjects were assigned the choice/no choice option by a random event unknown to the influencing agent. As anticipated, in the Interpersonal as compared to the Noninterpersonal condition, (a) threats produced greater compliance when a choice was offered than when it was not, and (b) promises and threats were more equivalent in gaining compliance when a choice was offered than when it was not. These results, which suggest that in a social setting individuals' concerns about freedom are interpersonally motivated, are discussed in terms of their relation to and implications for reactance theory.     

Sex differences in math performance: The role of children's approach to schoolwork

This research examined whether the tendency for girls to outperform boys in the classroom is due to differences in how girls and boys approach schoolwork. In 5th grade and then again in 7th grade, children (N=518) reported on how they approach schoolwork (i.e., achievement goals and classroom behavior), their learning strategies, and their self-efficacy in math; math grades and achievement test scores were also collected. Girls were more likely than boys to hold mastery over performance goals and to refrain from disruptive classroom behavior, which predicted girls' greater effortful learning over time. The sex difference in learning strategies accounted for girls' edge over boys in terms of grades. Girls did not do better on achievement tests, possibly because self-efficacy, for which there was also no sex difference, was the central predictor of performance on achievement tests.     

Sex differences in the attractiveness of hunter‐gatherer and modern risks

When compared with other demographics, young males are more likely to take a variety of risks (like skateboarding, using drugs) and use risky behaviors to attract romantic partners. This study extended research on risk by assessing the attractiveness of 101 different kinds of risks performed by males and females. As predicted, factor analysis revealed that the attractiveness of diverse risks clustered around two major dimensions: risks like those faced by hunter‐gatherer humans (e.g., handling fire and dangerous animals) and risks that are uniquely modern (e.g., driving without seat belts). Additionally, results confirmed that modern risks were rated as unattractive for both sexes, whereas hunter‐gatherer risks were rated as especially attractive when performed by males. Discussion focuses on cultural and evolutionary explanations for the link between risk and attractiveness.     

Sex differences in responses to the stranger in the strange situation

Children are exposed to differences in adult interactive styles from an early age. The Ainsworth Strange Situation. designed as a standard measure to activate attachment behaviors in the young child, allows us to examine the child's reaction to individual differences in strangers' styles. In the present study, the effect of 11 different strangers was examined to determine if different stranger styles influenced the scoring of behavioral ratings of the child's behavior in the Strange Situation. Boys and girls reacted differently to the different strangers. Eighteen-month-old children showed more variations in their reactions to different interactional styles than did 12-month-olds. Boys showed more resistance and avoidance to strangers who used more direction and initiation. Girls did not react this way. The results are discussed in terms of the child's expectations of sex-determined styles of interaction learned from past social interactions.This research was supported by Grant MH 37911 to the senior author from the Behavioral Sciences Research Branch, Family Processes Division, NIMH, U.S. PHS and Grant HD 17571 from the National Institute of Child Health and Development.     

Attributes and roles assigned to characters in children's writing: Sex differences and sex-role perceptions

This research examined the creative writing of 180 elementary school children for evidence of sex difference and sex-role perceptions. Stories were analyzed for frequency of male and female characters, attributes, and roles. Writers were equally divided by sex and into three age groups—grades 1–2, 3–4, and 5–6. Results suggest that the total number of characters, roles, and attributes was equivalent. However, the distribution of male and female characters, roles, and attributes differed with male and female writers. Female writers included significantly more female characters and assigned more attributes and roles to these characters. Nevertheless, in the stories of both male and female writers, there was a predominance of male characters and assignment of attributes and roles to male characters. The findings support the development and implementation of a nonsexist curriculum.     

Sex differences in children's discrepant perceptions of peer acceptance

Sex differences in children's play patterns during middle childhood are thought to promote greater awareness of social acceptance among girls compared with boys. The present study posited that girls are more discerning of peer acceptance than are boys; however, these sex differences were predicted to vary depending on how discrepant perceptions were assessed (i.e., inaccuracy versus bias). Additional differences were expected if children perceived acceptance by same- versus opposite-sex peers. Participants were 912 third through fifth graders (420 girls and 492 boys). Consistent with predictions, boys were more inaccurate than girls, but only for perceived acceptance by same-sex peers. As expected, girls were more negatively biased than boys, but only for perceived acceptance by opposite-sex peers. Results did not support the hypothesis that boys have more positively biased perceptions of peer acceptance than girls. Overall, these findings raise important issues regarding the evaluation of children's discrepant self-perceptions of peer acceptance.     

Forgiveness or breakup: Sex differences in responses to a partner's infidelity

Infidelities--sexual, emotional, or both--afflict many long-term romantic relationships. When a person discovers a partner's betrayal, a major decision faced is to forgive the partner and remain together or to terminate the relationship. Because men and women have confronted different adaptive problems over evolutionary history associated with different forms of infidelity, we hypothesised the existence of sex differences in which aspects of infidelity would affect the likelihood of forgiveness or breakup. We tested this hypothesis using forced-choice dilemmas in which participants (N = 256) indicated how difficult it would be to forgive the partner and how likely they would be to break up with the partner, depending on the nature of the infidelity. Results support the hypothesis that men, relative to women: (a) find it more difficult to forgive a sexual infidelity than an emotional infidelity; and (b) are more likely to terminate a current relationship following a partner's sexual infidelity than an emotional infidelity. The Discussion provides directions for future work on the determinants of breakup and the psychology of forgiveness.     

Sex differences in the relationship of height to children's actual and attributed social and cognitive competencies

In three studies, the relationship of children's height to both (a) adults' attributions regarding the children and (b) preschoolers' social and cognitive competencies were examined. Sex differences were consistent with stereotypic conceptions. In the first two studies, mothers of preschool children rated photographs of toddlers varying in height on a variety of social and cognitive abilities. The mothers also assigned punishment to the children for hypothetical transgressions. In Experiment 1, mothers rated the large boys as more competent than the average-sized and small boys (even when effects of mothers' perceptions of the children's ages were covaried). In Experiment 2, involving female stimuli, mothers rated small girls as being less able (especially less independent) than average-sized or tall girls. While the effect of height on mothers' attributions was still evident when the effects of perceived age of the children were covaried, the pattern of results was less clear. Mothers assigned more punishment to tall girls (but not tall boys) than to small girls regardless of perceptions of age. In Experiment 3, height was associated with boys', but not girls', competence on tasks of logical ability and boys' sociometric nominations of whom they prefer to play with (significant for girls, marginally significant for boys). Height was not highly correlated with peers' perceptions of competence. The implications of the research for the socialization process are discussed.The authors wish to express their gratitude to the parents, teachers, and children at the Child Study Laboratory, Students' Child Center, Palo Alto Preschools, and Tempe Preschool.

Sex differences in visual realism in drawings of animate and inanimate objects

Sex differences in a visually realistic drawing style were examined using the model of a curvy cup as an inanimate object, and the Draw-A-Person test (DAP) as a task involving animate objects, with 7- to 12-year-old children (N = 60; 30 boys). Accurately drawing the internal detail of the cup--indicating interest in a depth feature--was not dependent on age in boys, but only in girls, as 7-year-old boys were already engaging with this cup feature. However, the age effect of the correct omission of an occluded handle--indicating a transition from realism in terms of function (intellectual realism) to one of appearance (visual realism)--was the same for both sexes. The correct omission of the occluded handle was correlated with bilingualism and drawing the internal cup detail in girls, but with drawing the silhouette contour of the cup in boys. Because a figure's silhouette enables object identification from a distance, while perception of detail and language occurs in nearer space, it was concluded that boys and girls may differ in the way they conceptualize depth in pictorial space, rather than in visual realism as such.     

Toward a profile of the female voter: Sex differences in perceived physical attractiveness and competence of political candidates

Recent national attention has focused on women's voting behavior because of this group's increasing power to determine outcomes of local, state, and national elections. Research has not established whether males and females use the same decision rules in evaluating political candidates. Because of the link between perceived physical attractiveness and many positive attributes, the present study examined sex differences in ratings of attractiveness and competence of 44 men and women in the U.S. House of Representatives. Results indicated that males and females use similar rules in evaluating male politicans' attractiveness. Women show a pro-female sentiment in evaluating female politicians' competence. Physical attractiveness was positively related to perceived competence for both male and female politicians. Contrary to previous research, women voters showed a marked pro-female sentiment, and men were neutral, evaluating male and female politicians similarly.     

Gender differences,mediation, and disciplinary styles in children's responses to television

A sample of kindergarten and first-grade children was studied in a research center and at school to determine the extent to which family communication mediated their comprehension of television, as well as a series of cognitive skills necessary for such comprehension. Separate analyses were conducted for boys and girls, and results indicated that certain styles of family mediation facilitated comprehension more effectively for boys than for girls. Additionally, differential effects of two styles of discipline were found for each sex.This research was funded by a grant to Jerome and Dorothy Singer from the John D. and Catherine T. MacArthur Foundation entitled Television and Family Living Patterns.     

Sex differences in the relation of children's height and weight to academic performance and others' attributions of competence

The purposes of the present study were to examine the relation of elementary-school girls' and boys' height and weight to (a) teachers' and peers' perceptions of the children's independence and academic, athletic, and social competence; and (b) children's achievement test scores and grades. Teachers rated kindergarteners' through fourth graders' competence both at the beginning of the school year and four months later; first and third graders rated their peers' competence once midyear. In general, size and/or bulk were positively related to teachers' attributions of competence, grades, and achievement test scores for boys, especially for the older boys. Heaviness was negatively related to teachers' ratings of females' competence (especially athletic competence and especially for older girls). Moreover, large size (height not controlling for weight) was positively related to younger but not older children's nominations of males for athletic ability. The results are discussed in terms cultural stereotypes and their implications for the development of children's competence.     

Sex differences in the response to emotional distraction: an event-related fMRI investigation

Evidence has suggested that women have greater emotional reactivity than men. However, it is unclear whether these differences in basic emotional responses are also associated with differences in emotional distractibility, and what the neural mechanisms that implement differences in emotional distractibility between women and men are. Functional MRI recording was used in conjunction with a working memory (WM) task, with emotional distraction (angry faces) presented during the interval between the memoranda and the probes. First, we found an increased impact of emotional distraction among women in trials associated with high-confidence responses, in the context of overall similar WM performance in women and men. Second, women showed increased sensitivity to emotional distraction in brain areas associated with “hot” emotional processing, whereas men showed increased sensitivity in areas associated with “cold” executive processing, in the context of overall similar patterns of response to emotional distraction in women and men. Third, a sex-related dorsal–ventral hemispheric dissociation emerged in the lateral PFC related to coping with emotional distraction, with women showing a positive correlation with WM performance in left ventral PFC, and men showing similar effects in the right dorsal PFC. In addition to extending to men results that have previously been reported in women, by showing that both sexes engage mechanisms that are similar overall in response to emotional distraction, the present study identifies sex differences in both the response to and coping with emotional distraction. These results have implications for understanding sex differences in the susceptibility to affective disorders, in which basic emotional responses, emotional distractibility, and coping abilities are altered.     

Sensitivity to viewpoint in children's drawings of objects and relations between objects.

Previous literature suggests that young children are relatively insensitive to viewpoint, only showing their view when the task is manipulated to provoke it. In contrast, older children appear to become more sensitive to viewpoint and it has been claimed that there is a developmental progression toward use of linear perspective as a means of drawing a view-specific scene. This study investigates sensitivity to viewpoint by manipulating it directly. Children between the ages of 6 and 14 years were asked to draw an L-shaped array of three cubes from one of three views: frontal eye level, frontal looking down, and corner looking down. At every age children showed sensitivity to their view in the sense that there were consistent differences between the drawings produced in the three viewing conditions. In the case of younger children this did not lead to an accurate portrayal of either their view or the array relations. Older children portrayed their view and the array relations more accurately, and viewpoint had a strong effect on the choice of projection system both within and between objects. There was no evidence of a general progression toward use of linear perspective.
