Personality, longevity, and successful aging among Tokyo metropolitan centenarians.

The purpose of our study was to examine two hypotheses: 1) that androgyny and Type B behavior are related to longevity; and 2) that personality characteristics associated with longevity may also be related to successful aging. Participants were eighty-two centenarians (37 men and 45 women) who were compared with 605 elderly in their sixties, seventies, and eighties. Both groups were living in the Tokyo metropolitan area. We used the Bem Sex Role Inventory and Bortner Pattern A Behavior Scales to measure personality, and the Rosenberg Self-Esteem Scale and Cattell Anxiety Scale to measure successful aging. We found that androgyny was not more prominent among centenarians than masculinity, femininity, or undifferentiated. In fact, more femininity was observed. Additionally, we found that more women were classified as feminine than were men. The results indicated more Type B's among centenarians than among those in their sixties and more women than men showed Type B behavior. Our hypothesis that Type B behavior is related to longevity was supported. We observed lower self-esteem for femininity than for either the masculinity or androgyny. We also observed that anxiety was lower for femininity than masculinity but higher than androgyny among women. Type B women showed lower self-esteem than Type A women. Type B men showed lower anxiety than Type A men. We conclude that femininity is related to longevity and that androgyny may be related to successful aging. Further, we suggest that Type B behavior is associated with longevity, but its relationship to successful aging differs between men and women.

[Risk factors to periventricular-intraventricular hemorrhage in newborns weighing less than 2000g]

OBJECTIVE: To study the incidence and analyze risk factors to neonatal periventricular-intraventricular hemorrhage; to suggest a working protocol for diagnosis in newborns at risk.METHODS: This is a cohort prospective study including 120 out of 129 children weighing less than 2000g born from May 18 th, 1994 to May 17 th,1995 at the Hospital das Clínicas da UFMG. The study group comprised 39 newborns with the ultrasound diagnosis of periventricular-intraventricular hemorrhage; the control group comprised 81 newborns who although submitted to the same evaluation protocol did not show any echographic signs of hemorrhage. The ultrasound examinations were all done by the same researcher who was not aware of the clinical history or the neurologic and laboratory examinations. The hemorrhage was classified according to Papilés criteria: grade I (13%); grade II (7%); grade III (9%) and grade IV (3%).RESULTS: Low gestational age, low birth weight, masculine sex, vaginal delivery, and neonatal sepsis were significantly associated (p < 0.05) with periventricular-intraventricular hemorrhage in univariate analysis. Apgar score in the first or fifth minute and Battagliás and Lubchenkós classification for the weight in relation to gestational age were not predisposing factors to the hemorrhage. Low gestational age (p = 0.002), vaginal delivery (p = 0.037), and masculine sex (p = 0.016) kept statistical significance after multivariate adjustment. Birth weight may substitute for gestational age in the multivariate model because they are highly associated. The best cutoff point to screen for periventricular-intraventricular hemorrhage was 1750 g instead of the traditionally adopted point of 1500 g. CONCLUSIONS: The incidence of neonatal periventricular-intraventricular hemorrhage was similar to those reported by other studies. Low gestational age or low birth weight, vaginal delivery and masculine sex were the most important risk factors to the hemorrhage. The screening cutoff point of 1750 g seems to be more adequate than the commonly used birth weight of 1500 g.

How accurately do young children and adults discriminate the gender of natural faces?

The effects of gender-relevant facial features and hairstyles on discrimination of sex of photographed men and women were examined. The stimuli were 36 photographs of natural faces: 9 masculine-males, 9 feminine-males, 9 masculine-females, and 9 feminine-females. Each of the nine faces had one of three hairstyles, hair concealed, short hair, or long hair. 33 children (M age=5:10) and 28 adults were asked to identify the sex of each stimulus. Children had difficulties with cross-gender faces and cross-gender hairstyles, such as a feminine-male face with long hair. Adults' discriminations were accurate except for masculine-female faces, while children's decisions depended both on hairstyle and internal facial features. Children's discriminations might be based both on their perceptual skill in detecting critical visual features and their knowledge of men and women.

Facial action patterns, electromyography, and moods in response to an insoluble task as a function of sex and sex-role differences.

College students of either androgynous or sex-typed orientation were randomly assigned to either an insoluble concept-formation task or a solvable one. Posttreatment scores were compared for measures of dysphoric mood (Multiple Affect Adjective List), electromyographic responses (corrugator and zygomatic), and discrete facial responses (Facial Action Coding System). In Study 1, 18 androgynous women were compared to 16 feminine women; in Study 2, 16 androgynous men were compared to 16 masculine men. The insoluble task was associated with more corrugator activity (frowning) than the solvable task in both studies. Feminine women displayed more corrugator responses across both tasks than androgynous women. However, masculine men did not differ from androgynous men in over-all corrugator response activity. Androgynous women smiled more than feminine women on the facial action coding measure. Men subjected to the insoluble task reported significantly more anxiety, depression, and hostility. Masculine men scored higher on anxiety during the insoluble task than androgynous men, while the latter scored somewhat higher on anxiety in the other condition.

Psychological gender, hand preferences, and sex differences in book-carrying styles.

Individuals with stronger sex-role identities may be expected to show greater conformity to sex-typed behaviors. Proceeding from this assumption, the sex-role status and sex of students using different styles of carrying books were compared. This study also examined whether over-all hand preference or age were related to carrying styles or sex-role status. Subjects completed a questionnaire comprised of the 24-item Personal Attributes Questionnaire of Spence and Helmreich, a 6-item scale of hand preference and a self-rating of sex-role identity. Afterwards, each subject's carrying style was covertly observed and recorded. Most subjects carried their materials in a sex-typical way or in book bags (for which no sex-typed carrying styles were discovered). As in previous studies, men in this study scored higher than women on masculinity and androgyny and lower on femininity. Hand preference was not related to sex-role status. Carrying style was not significantly correlated with any of the predictor variables for men, perhaps because almost no variance in carrying style was observed among them. Women who used masculine carrying styles tended to be older, have greater instrumentality, and a more masculine identity.

Field independence as a function of sex, sex-roles, and the sex-role appropriateness of the task.

Two experiments were conducted to explain the sex difference in field independence by reference to socialization factors. It was hypothesized that the sex-role appropriateness of the task as masculine or feminine-typed would influence the performance of masculine and feminine women in a manner congruent with their sex-role orientation. 28 pilot subjects and 100 subjects in Study 2 were equally divided between the sexes. Both studies used the Bem Sex-role Inventory, but different versions of the Embedded Figures Test. The over-all results suggested that feminine women varied their performance according to task appropriateness, although not always in a manner congruent with their sex-role orientation. Androgynous individuals and masculine men did not alter their performance.

Sex-role orientation of college students and their same-sex parents.

The study examined similarities and differences between sex-role orientations of college students and their same-sex parents. College undergraduates filled out the Bem Sex-role Inventory twice: once to describe themselves and the second time to describe their same-sex parents. The inventory was also used to obtain parental self-reports. Compared to their perceptions of their same-sex parents, male students described themselves as more feminine and female students described themselves as more masculine. Also, male students described their fathers as less feminine and female students described their mothers as both less masculine and less feminine than the parents described themselves. Students' femininity scores correlated significantly with the parental femininity scores both actual and perceived, however, no consistent relationship was found for the masculinity scores. Androgynous students and students with the reversed sex-role orientation perceived their parents as androgynous and reversed, respectively.

Endorsements by Mexican-Americans of the Bem Sex-Role Inventory: cross-ethnic comparison.

Gender-related personality traits among Mexican-American men and women were examined. The sample consisted of 307 Mexican-Americans (150 women, 157 men) in a predominantly Mexican and Mexican-American community in South Texas. Mexican-American men scored significantly higher than the women on eight masculine items, whereas Mexican-American women scored higher than the men on four feminine items. A comparison between the scores of Mexican-Americans on the Bem Sex-Role Inventory with those of the original sample in the inventory's manual showed that the scores for the Masculinity and Femininity subscales for both Mexican-American men and women were not significantly different from those of the original sample. A significant difference, however, was found on some of the items of the inventory. Analysis also indicated that more Mexican-American men were categorized as Feminine and Androgynous than were non-Hispanic Euro-American males in the original sample. Among Mexican-American women there were more individuals classified as Masculine and Undifferentiated and a lower percentage as Feminine than among the original sample. Implications and recommendations based on the results are discussed.

Hypermasculinity and academic goal-setting: an exploratory study.

The relation between gender-role percepts and academic goal-setting was explored. An inventory examining the aspects of masculinity that would facilitate or inhibit academic goal-setting was developed based on a literature review of how masculinity relates to academic behaviors. A diverse sample of students (120 male, 147 female, 14 not indicating sex) was measured on three aspects of sex and academic goal-setting behavior. Factor analysis confirmed the content validity of masculine factors having facilitative (Mastery Competitiveness) and inhibitory (Antisocial Competitiveness) academic properties. Regression analyses indicated that sex-role orientations (Competitiveness and Hypermasculinity) significantly predicted academic goal-setting behaviors (R2 = .136). Finally, men scored higher than women on the subscales measuring Hypermasculinity and Antisocial or Competitiveness, while there were no sex differences on the Mastery Competitiveness subscale. The implications of these findings and suggestions for research are discussed.

Evidence for an association between gender-role identity and a measure of executive function.

Two studies assessed the relation between gender role and executive function. In Study One (N = 234) analyses indicated that among college students executive function, assessed by the Coolidge and Griego scale, is related to masculine gender-role classification, measured by the Bem Sex-role Inventory. This relationship remained significant when biological sex was controlled. Further, factor analysis of the Bem Sex-role Inventory identified six components, three related to executive function. Two of these scales were associated with masculine characteristics, and the third was associated with the denial of several feminine items. Study Two (N = 53) further assessed the relationship among undergraduates through additional measures of executive functions and mood, in addition to the Bem Sex-role Inventory. In this study, executive functioning, as measured by the Coolidge and Griego scale, was again generally related to masculinity. Psychological well-being was not related to gender identity or executive functioning.

Effects of leaders' and evaluators' sex on sex-role stereotyping of charismatic leaders.

This study extends research on sex and leadership by examining the relation between evaluators' and leaders' sex and the sex-role stereotyping of charismatic leaders. A total of 219 students (110 men and 109 women) from a large northeastern university rated charismatic leaders depicted in vignettes using the revised Bem Sex-Role Inventory: overall, the leaders were rated higher on masculinity than femininity. Analysis by sex of evaluator and leader showed masculinity was higher in all cases except when male charismatic leaders were evaluated by women. In this case, the results support an androgynous view, i.e., high on both masculinity and femininity.

Sex roles in addiction: defense or deficit?

Overly masculine, "macho" males and feminine, "seductive" females are found in clients addicted to alcohol and/or drugs. Contrary to expectations, on the Bem Sex-Role Inventory males (N = 60) rated themselves, in descending order, Undifferentiated, 38.5%; Feminine, 33%; Masculine, 17%; and Androgynous, 11.5%. Females (N = 36), more predictively, saw themselves as Feminine, 50%; Undifferentiated, 31%; Androgynous, 11%; and Masculine, 8%. Independent variables of age, income, marital status, severity of addiction, length of inpatient treatment, level of education, and parental marital status did not significantly affect the results. Extreme sex-role dress and behavior appear to be a defense against the overall damage resulting from the addictive disease rather than a contributor to or cause of the disease.

The relation of gender-role classifications to the prosocial and antisocial behavior of Chinese adolescents.

The author investigated the relation between gender-role classifications and prosocial and antisocial behavior for 505 Chinese adolescents in grades 7 to 12. The author found that (a) boys were more antisocial than girls were, (b) there was no significant gender difference in prosocial behavior, (c) prosocial behavior was associated positively with both masculinity and femininity, (d) delinquent behavior was associated positively with masculinity, (e) gender-role classification that was consistent with one's biological gender (e.g., femininity in girls) was more salient in predicting one's prosocial behavior than was a gender-role classification that was not consistent with one's gender (e.g., femininity in boys), (f) delinquent behavior in the feminine group was significantly lower than it was in the other 3 gender-role groups (masculine, androgynous, undifferentiated), and (g) adolescents in the undifferentiated group tended to be less prosocial and fairly antisocial, and their social behavioral pattern was the least favorable among the four gender-role classifications.

Sex role group differences in specific, academic, and general self-efficacy.

The primary purpose of this study was to examine sex role group differences (androgynous, masculine, feminine, and undifferentiated) in three different levels of self-efficacy (general, academic, and course specific). A sample of 215 undergraduate participants completed the three measures of self-efficacy and the sex role measure. Results showed that there was a multivariate significance among the sex role groups in the three levels of self-efficacy and that both masculine and androgynous groups had significantly higher general and academic efficacy means than the undifferentiated or feminine groups. The major findings in this study are largely consistent with findings of previous researchers, supporting the theory that masculinity may be a key construct in the differentiation of individuals in self-efficacy, which has been shown to be an important predictor of achievement.

Effect of grammatical gender on visual word recognition: evidence from lexical decision and eye movement experiments.

Lexical decision times and eye movements were recorded to determine whether grammatical gender can influence the visual recognition of isolated French nouns. This issue was investigated by assessing the use of two types of regularities between a noun's form and its gender--namely ending-to-gender regularities (e.g., the final letter sequence -at appears only in masculine nouns and, thus, is predictive of masculine gender) and gender-to-ending regularities (e.g., feminine gender would predict the final letter e, whereas masculine gender would not). Previous studies have shown that noun endings are used by readers when they have to identify gender. However, the influence of ending-to-gender predictiveness has never been investigated in a lexical decision task, and the effect of gender-to-ending regularities has never been evaluated at all. The results suggest that gender information can influence both the activation stage (Experiments 1 and 3) and the selection stage (Experiments 2 and 3) of the word recognition process.

[The effect of androgens upon the differentiation of Cowper and Bartholin glands in rat fetuses (author's transl)].

In the present paper, a study is made of the normal structure shown in Bartholin and Cowper glands of 100 female fetuses and 100 male fetuses of Wistar rats at the end of gestation, with the structure of bulbouretral glands that formed in 70 female fetuses of the same species and period of gestation masculinized by androgens. In relation to the Bartholin glands, whose bilateral sketch is constant in the fetuses, we can affirm that it shows significant differences of structure with regards to the sketch of the Cowper gland. On the opposite, the histologycal details of the latter, are entirely identical to those shown by the bulbouretral glands of the masculinized female fetuses, a fact which permits us to affirm that these are authentic Cowper glands, not only because of their position, but also because of their structure. This morphological data corresponds to a masculinization phenomenon and demonstrates that the Bartholin and Cowper glands are very sensitive to the effect of androgens during gestation.

Gender-related personal attributes and psychological adjustment among U.S. Army soldiers.

Personality characteristics associated with successful adaptation to military life are often described in gender-related terms. However, valid, reliable measures of gender-related personality characteristics have not been established for military populations. The purpose of this study was to validate an instrument for measuring gender-related personality characteristics in an active duty population. The Extended Personal Attributes Questionnaire was administered to 1,060 male soldiers and 305 female soldiers in U.S. Army support units. Results of a factor analysis indicated that there are three separate factors. The first denotes negatively valued aggressive traits (Negative Masculinity), the second denotes negatively valued passive traits (Negative Femininity), and the third combines positive instrumental and positive expressive traits, referred to as the Combined factor. Although positive instrumental traits (referred to as Masculinity) were related to fewer psychological symptoms, Negative Masculinity and Negative Femininity were associated with increased psychological symptoms. Positive expressive traits (referred to as Femininity) were unrelated to psychological symptoms.

[Effects of automobile lead on the general growth and sexual activity of the rat].

To identify the active element of automotive exhaust gas responsible for masculine infertility, previously proved by our laboratory, we undertook these experiments. Four hundred young male and female rats were exposed during two months (30 min/d) to three types of automotive exhaust gases. The first type emanated from an engine running on gasoline with lead, the second from an unleaded gasoline engine, the third from a diesel engine. These three engines had the same power (5 horsepower vehicles < 3.5 tons). For the first type of emissions, some lead deposits were found in the lungs by histologic techniques. This gas also induced in male rats the atrophy of the testicle, seminal vesicle and epididym, certain pathological changes in spermatogenesis shown by the histologic study, and a decrease of the serum's testosterone level. In female rats, the relative weights of the ovary and uterus, as well as the percentage of the arrival of oestrus, were not affected by the gaseous treatment. Both the second and third types of gases seemed less active on the masculine sex as far as these parameters are concerned. Our study suggests that, for light vehicles, leaded gasoline pollutes more than unleaded gasoline or diesel fuels, and that the lead present only in the first type would be the active element responsible for the masculine infertility and body weight gain reduction in rats.
