Aggressive behavioral characteristics,hormones, and sexual orientation in men and women

Aggressive behavioral characteristics were assessed in groups of men and women by a self-report instrument, the Aggression Inventory, in which adult males reported more physical and verbal aggression than did females. Furthermore, males had higher scores on measures of impulsiveness and lack of frustration tolerance than did females, while women were more likely to avoid confrontation. In a second study, groups of male and female homosexuals and heterosexuals completed this Aggression Inventory after having blood samples taken to assay resting levels of testosterone (T) and estradiol (E). Groups of subjects within each gender were closely matched in terms of age, education, and vocational interests. Women were matched for the same time in their menstrual cycle (early follicular phase). Among men, homosexuals were indistinguishable from heterosexuals on all measures of aggression. Lesbians did not differ from heterosexual women on any aggression subscale except physical aggression, in which the homosexual women had lower scores. T and E were positively correlated with several indices of aggressive behavioral characteristics in men but were negatively correlated with those same measures in women.     

The Effects of Sex,Status, and Ability on Helping Behavior1

Protests against affirmative action articulate the concern that qualified white males will be subordinated to less qualified women and minorities. To examine the possibility that the reversal of traditional status relationships rather than competence inequity underlies resistance to affiimative action, a study was conducted in which subjects interacted with a male or female who was introduced as their supervisor or subordinate and as either higher or lower in ability than themselves. The results indicate that status, not ability, influences the frequency of helping women, whereas ability, not status, primarily influences helping behavior toward men. Specifically. female subordinates were helped more than females supervisors, regardless of ability, while high-ability males elicited more help than low-ability males, independent of status. Subsequent ratings revealed that although subjects acknowledged the greater competence of high-ability males, they did not evaluate high-ability females as more competent than themselves.     

Love, sex roles, and psychological health

College students were administered a series of questionnaires designed to determine the association between psychological health, involvement in a romantic relationship, and the quality of love in a relationship. As predicted, subjects who had been involved in at least one love relationship scored significantly higher on a measure of self-actualization than individuals who had never been in love. In addition, it was found that level of self-actualization directly correlated with the degree of healthy love (Maslow's B-love) among individuals who had been involved in a romantic relationship. Among individuals who had terminated their relationship, those who demonstrated higher levels of self-actualization felt less resentment toward their ex-lover. Furthermore it was discovered that females show a higher level of B-love than males, but contrary to predictions the length of a romantic relationship did not influence B-love. It is concluded that the results of this study are essentially consistent with Maslow's theories about self-actualization, hierarchy of needs, and healthy love.     

Effects of sexual attitudes and physical attractiveness on person perception of men and women

A sample of 180 males and 180 females completed person perception measures for stimulus women who varied in physical attractiveness and permissiveness of sexual attitudes. The results indicated that both physical attractiveness and sexual attitudes had strong effects on peson perception. Physically attractive stimulus women were rated higher than the unattractive stimulus women on a physical appeal factor and an item measuring interpersonal attraction. The sexually conservative women were rated higher on an evaluative factor, lower on a personability factor, and higher on the interpersonal attraction item than the sexually permissive stimulus women. It was also found that the effects of physical attractiveness were greater for males than for females and that women rated the sexually permissive stimulus women less favorably than did men.     

Role of neonatal androgens in sexual differentiation of brain structure, scent marking, and gonadotropin secretion in gerbils

Gerbils display a sexually dimorphic scent marking behavior that responds to testosterone (T) in adulthood and develops under the influence of testosterone perinatally. A complex of cell groups between the preoptic area and anterior hypothalamus of the gerbil brain is also sexually dimorphic and responsive to testosterone. One of these cell groups, the sexually dimorphic area pars compacta (SDApc), usually exists only in males. Even when given testosterone, adult female gerbils rarely have an SDApc. To determine if the SDApc develops under the influence of testosterone, male gerbils were castrated or given sham operations on the day they were born or 1 day later, or were not manipulated. Female gerbils were injected subcutaneously with 0, 50, or 100 micrograms testosterone propionate (TP) on the day after birth. When given ovarian transplants as adults, neonatally castrated males scent marked at low levels typical of females. Neonatally androgenized females given testosterone as adults scent marked at high levels typical of males. Neonatal castration did not affect the probability that the SDApc would develop, but neonatal androgenization did. Half the females given either dose of TP as neonates had SDApcs bilaterally. The sizes of the SDApcs present in females depended on the dose of testosterone given neonatally. The larger dose produced larger SDApcs. The 100-micrograms dose of TP also defeminized gonadotropin secretion, but the 50-micrograms dose did not. The castration of males neonatally prevented the defeminization normally caused by endogenous testosterone. Both groups of neonatally castrated males formed corpora lutea in their ovarian transplants, but control males did not.     

Peripheral and central sex steroids have differential effects on the HPA axis of male and female rats

Sex differences in hypothalamic-pituitary-adrenal (HPA) function were examined in gonadectomized male and female rats given equivalent sex hormone replacement regimens either using subcutaneous silastic implants (Experiment 1) or cannula implants in the medial preoptic area (MPOA) (Experiment 2) containing either dihydrotestosterone (DHT), testosterone propionate (TP), estradiol benzoate (EB), or left empty (control). Plasma was obtained before and after 20 min of restraint stress to determine plasma ACTH, corticosterone, and CBG levels as measures of HPA function. Consistent with the literature, androgens decreased, and estrogen increased these measures of HPA function, although peripheral implants were more effective than MPOA implants. Gonadectomy and sex hormone treatment did not eliminate sex differences; overall, females had higher levels than males on measures of HPA function. Analyses of variance (ANOVA) indicated interactions of sex and sex hormone treatment on CBG levels and post-stress corticosterone levels in Expt. 1. The results suggest that sexual dimorphisms influence HPA function even when males and females are given equivalent physiological doses of gonadal steroids, and that the relevant sexual dimorphisms involve both the periphery and the CNS.     

The Effect of Experience on the Goal-Setting Behavior of Type A and Type B Individuals

The effect of experience on the goal-setting behavior of Type A and Type B individuals was assessed using anagram tasks. Sixty men and 60 women were administered the Jenkins Activity Survey as well as a questionnaire assessing their previous experience with anagram tasks. Before each of three anagram trials, subjects set a performance goal and indicated how certain they were that they could reach that goal. The analyses indicated that Type A men had the largest differences between performance goals and actual performance, even though men, in general, were more certain that they would reach their goals. Differences across trials, however, decreased for all individuals. Men with the most prior self-reported experience were least satisfied with their performance. Of interest was the finding that Type B women had higher difference scores than did Type A women.     

Enjoyment of sexualization: is it different for men?

We elucidated the Enjoyment of Sexualization (ES) construct in a sample of 206 female and 118 male undergraduate students. Our male ES Scale had high reliability, and confirmatory factor analyses indicated that a univariate structure was appropriate for both men and women. ES added to the prediction of self‐esteem and number of sexual partners (but not body shame) after controlling for self‐objectification; gender did not moderate these relationships. The relationship between ES and number of sexual partners was moderated by attractiveness such that individuals who believed themselves to be more attractive had more sexual partners at high levels of ES. Furthermore, ES was distinguishable from the conceptually‐related self‐objectification construct with regard to Big Five personality. Finally, results suggested that ES might be less harmful than self‐objectification.     

Sex of Supervisor, Sex of Subordinate, and Subordinate Job Satisfaction

It was hypothesized in the present research that there would be significant differences in the job satisfaction of subordinates depending upon the interaction between their sex and the sex of their supervisors. Using job satisfaction data from 139 employees, it was found that: (a) female subordinates supervised by male supervisors were less satisfied with supervision than those supervised by women, (b) females working under males reported a lower level of satisfaction with their co-workers than females supervised by females or males supervised by males, and (c) women who had female supervisors indicated a higher level of satisfaction with their work than men with male supervisors. Contrary to traditional stereotypes of women supervisors, the results suggested that these stereotypes might not be important in long-term, real-world situations.     

Self-evaluations of male and female managers

Two separate samples of males and females holding first-level management positions in United States organizations completed questionnaires which asked for self-evaluation on a number of job-related characteristics and for attributions of causality for successful and unsuccessful job experiences. In support of previous research, results indicated that males evaluated their performance more favorably than did women, and rated themselves as having more ability and greater intelligence. Men also saw ability as more responsible for their success than did women, but the sexes did not differ in attributions to luck, effort, or task. Implications for equal opportunity and potential for change are considered.     

Body Esteem: An Exception to Self‐Enhancing Illusions?1

Participants were 192 university students (96 males, 96 females) who completed the Body Esteem scale (Franzoi & Shields, 1984) under instructions to rate their feelings about their own bodies, rate their feelings about a specific or “average” student's body, and rate the importance they and others attached to these feelings. One of the findings is that when individuals perceived themselves as less positive on a particular desirable physical trait, they also rated the trait as less important to possess in the first place. The only exception to this was women's weight concern. It was also found that men generally rated themselves higher on body‐esteem subscales than they rated other men, while women did not exhibit such self‐serving evaluations of their bodies. One implication from these results is that the same self‐enhancement strategies successfully employed by individuals in other areas of self‐evaluations were not successful in enhancing one's body esteem, especially women's weight concern.     

Body Image: Gender,Ethnic, and Age Differences

Abstract

Using figure drawings (E. Fallon & P. Rozin, 1985), 120 male and female U.S. college students–African American, Hispanic, and Caucasian–indicated their current and ideal figures, the figures that they considered most attractive to the opposite sex, and the opposite-sex figures most attractive to themselves. Dissatisfaction with body shape was greater among the women regardless of ethnicity. Both the men and the women misjudged which shapes the opposite sex would rate as most attractive: The women guessed that the men preferred shapes thinner than those that they actually reported. The African American women had the most accurate perceptions of what the men found attractive, whereas the Caucasian women had the most distorted views. The men guessed that the women preferred shapes bulkier than those that they actually indicated. These findings may be relevant to the lower incidence of eating disorders among African American women and the higher incidence of such disorders among Caucasian women.     

The effect of subject's gender on judgments of similarity and choice of a comparison other

This study examined the implications for social comparison theory of the proposition that women have lower self-confidence than men when there is a socially defined standard of performance. To this end, it was hypothesized that women would judge themselves to be similar to a lower ranked person, whereas men would judge themselves to be similar to a higher ranked person. Furthermore, it was hypothesized that women would choose to see a score lower than their own, whereas men would choose to see a score higher than their own. The results on the measure of similarity indicated that men did judge themselves to be similar to a higher ranked person, whereas women showed no consistent preferences in their judgments of similarity. The results on the choice of a comparison other were not as clear-cut.     

Hormonal changes of intimate partner violence perpetrators in response to brief social contact with women

This study investigated whether men with a history of real-life aggressive, dominant behavior show increases in testosterone and cortisol levels after brief social contact with women. Furthermore, we tested the prediction that such changes in hormones would be larger than those observed previously in young male students. Sixty-seven male participants convicted of intimate partner violence (IPV) either had brief social contact with a female confederate (experimental condition) or a male confederate (control condition). We also performed meta-analyses to investigate whether IPV perpetrators' hormonal responses were larger than the typical responses of young male students in prior studies. All statistical analyses were preregistered. Change in testosterone did not differ across experimental conditions, and testosterone in the IPV perpetrators actually declined from baseline in the female confederate condition. Our meta-analysis showed that this testosterone decrease was different from the testosterone increase typically observed in young male students. The cortisol levels of IPV perpetrators did not change in response to contact with women. This result was consistent with our meta-analysis since young male students also did not experience a cortisol change in response to interactions with women. In sum, our findings provide no evidence that male IPV perpetrators exhibit larger hormone increases to brief interactions with women, although it is possible that the men in this sample did not perceive the social contact period as a courtship opportunity. These results suggest that hormone reactivity to social encounters may differ across subject populations and depend on how subjects perceive social situations within laboratory settings.     

Organizational and extraorganizational factors affecting stress,employee well-being,and absenteeism for males and females

The purpose of this research is to examine separately for males and females, the effects of different sources of job and life stress on the emotional and physical well-being of those individuals, and in turn on absenteeism. Results using a sample of 170 males and 204 females indicated that females experienced higher levels of job stress, absenteeism, and poorer emotional well-being. Patterns of relationships for males and females were similar, however, the data suggest that sex moderates the effects of different sources of stress on emotional and physical well-being and absenteeism. The model developed as a part of this research was more complicated for females than for males.     

Hormones and competitive aggression in women

This study used diaries of competitive interactions to explore the relationship between hormones and competitive aggression in women. Thirty women completed approximately 10 diary entries each. In each entry, the women described a recent competitive interaction they had engaged in and noted whether it was expressed aggressively or through other tactics. Each woman received a score for the fraction of her competitive interactions that were expressed using physical aggression, verbal aggression, nothing overt, and so on. Hormones (total testosterone, free testosterone, androstenedione, estradiol, and cortisol) were measured in serum early in the follicular phase. Results indicate that women with low levels of androstenedione and total testosterone were less likely to express their competitive feelings overtly, while women with high levels of androstenedione were more likely than other women to express their competitive feelings through verbal aggression. Estradiol was unrelated to competitive tactics, but women with high estradiol levels reported fewer competitive interactions over athletics than did other women. Aggr.

Sex differences in the nature,realism, and correlates of body image

The present study examined sex differences in the nature and realism of body-image satisfaction, and the extent to which sex and sex role ideology moderated the relationships of body image to other indices of self-esteem and well-being. Accordingly, scales assessing body cathexis, self-esteem, depression proneness, and sex role ideology, as well as a questionnaire assessing perceptions of weight and dieting activities, were completed by 135 college women and 129 college men. As expected, women indicated significantly greater dissatisfaction with their bodies than did men. Women were likely to perceive themselves as overweight or slightly overweight, regardless of their actual weight, and most wanted to lose weight. Men who were dissatisfied tended to perceive themselves as underweight and wanted to gain rather than to lose weight. For both sexes, less positive attitudes to ward one's body were related to lower levels of self-esteem, although the relationship was significantly stronger for women than for men. The relationship between body attitudes and self-esteem was of approximately equal magnitude among traditional vs feminist women. For both sexes, more negative attitudes towards one's body were related to greater proneness to depression. Implications for further research are discussed.     

The determinants of parents' beliefs about the intelligence their children: A study from Hong Kong

One hundred and ninety‐three Hong Kong parents (mean age 42.2 years) were given a structured interview / questionnaire concerning their own and their children's self‐estimated overall and multiple intelligence. Previous research suggested that males tend to give higher overall “g” estimates to their children and themselves than do females, as well as higher scores on mathematical and spatial intelligence (Furnham, 2001). Further, studies in the West suggest that parents think their children are significantly brighter than they are and that their sons are brighter than their daughters. Estimates were lower than those found in Western populations but, even so, males rated their own mathematical and spatial intelligence higher than did females. Hong Kong Chinese parents did not think their sons were brighter than their daughters. The seven multiple intelligences factored into three clear factors for self and children, and regressions indicated that it was “academic” intelligence (verbal, mathematical, spatial) that was most “g” loaded. The child's age and the self‐rated overall IQ of both the parents were the best predictors of the child's overall estimated IQ. Less than a third of the parents had taken an IQ test or believed they measured IQ very well. Those who were more likely to be better educated, had taken an IQ test, and believed intelligence was inherited were more likely to award themselves higher overall IQ scores. Results are compared with the British studies in the same area.     

Low- and high-testosterone individuals exhibit decreased aversion to economic risk

Testosterone is positively associated with risk-taking behavior in social domains (e.g., crime, physical aggression). However, the scant research linking testosterone to economic risk preferences presents inconsistent findings. We examined the relationship between endogenous testosterone and individuals' economic preferences (i.e., risk preference, ambiguity preference, and loss aversion) in a large sample (N = 298) of men and women. We found that endogenous testosterone levels have a significant U-shaped association with individuals' risk and ambiguity preferences, but not loss aversion. Specifically, individuals with low or high levels of testosterone (more than 1.5 SD from the mean for their gender) were risk and ambiguity neutral, whereas individuals with intermediate levels of testosterone were risk and ambiguity averse. This relationship was highly similar in men and women. In contrast to received wisdom regarding testosterone and risk, the present data provide the first robust evidence for a nonlinear association between economic preferences and levels of endogenous testosterone.     

Body image: gender, ethnic, and age differences

Rozin, 1985), 120 male and female U.S. college students--African American, Hispanic, and Caucasian--indicated their current and ideal figures, the figures that they considered most attractive to the opposite sex, and the opposite-sex figures most attractive to themselves. Dissatisfaction with body shape was greater among the women regardless of ethnicity.

The African American women had the most accurate perceptions of what the men found attractive, whereas the Caucasian women had the most distorted views. The men guessed that the women preferred shapes bulkier than those that they actually indicated. These findings may be relevant to the lower incidence of eating disorders among African American women and the higher incidence of such disorders among Caucasian women.
