Sex differences in nonverbal communication

An experiment was conducted to determine the relationship between sex-role attitudes, affiliation, and dominance and nonverbal communication styles in men and women in same- and opposite-sex dyads. Women were found to elicit more warmth and men more anxiety from their partners. Evidence was found for a possible monitoring mechanism through which women adjust their nonverbal communications to fit the male in the interaction. Liberalism in sex-role attitudes was found to correlate with nonverbal warmth in men. The nonverbal presentations of men and women in the microprocesses of dyadic interaction were found to relate significantly to the macrostructure of societal sex roles.This research was supported by NSF Grant GS36814.

Sex differences in dominance behavior

The effect of the status characteristic of sex on dominance behavior was investigated as a function of a challenger's sex and in relation to one's sex-role orientation. Dyads composed of a student and a confederate recorded individual preferences, then joint decisions, for the more attractive picture of 20 pairs of pictures. The number of challenges a student sustained each time a disagreement occurred regarding the more attractive picture of a pair was recorded. Males withstood significantly more challenges against their preferences than females did (p<.006). However, no differences were found as a function of the sex of one's partner; nor did the Attitudes toward Women Scale (AWS) prove to be a good predictor of dominance. Results were discussed in terms of predictions made by the theory of status characteristics.This report is based on a master's thesis written by the first author under the sponsorship of the second and submitted in partial fulfillment of the requirements for the MA degree at the Graduate School of the University of Alabama. Portions were presented as part of of the paper session Compliance-Conformity/Altruism-Helping Behavior at the annual meeting of the Southeastern Psychological Association, New Orleans, March 1976.The authors would like to express their appreciation those who served as confederates in this study: Jim Dodds, Rochelle Hanan, Eunice Fogarty, and Rex Hall.     

Sex differences in performance and hemispheric organization for a nonverbal auditory task

Musically experienced and inexperienced men and women discriminated among fundamental-frequency contours presented either binaurally (i.e., same contour to both ears) or dichotically (i.e., different contours to each ear). On two separate occasions, males made significantly fewer errors than did females in the binaural condition, but not in the dichotic condition. Subjects with prior musical experience were superior to musically naive subjects in both conditions. The dichotic pitch task produced a left-ear advantage, which was unrelated to gender or musical experience. The results suggest that the male advantage on the binaural task reflects a sex difference in the coordination of the two hemispheres during conjoint processing of the same stimuli rather than a difference in the direction or degree of hemispheric specialization for these stimuli.

Sex and birth order differences in filial behavior

Personal interviews were conducted with 499 children of elderly white widows. Results showed no birth order differences in the provision of assistance to the elderly; however, there were significant sex differences. Daughters performed more caretaking activities and social services and provided more emotional support for their mothers than did sons. Sons had a tendency, though insignificant, to provide more advisory assistance to their mothers. After adjusting for situational differences between daughters and sons a sex difference remained only for the provision of emotional support.     

Sex differences in spontaneous alternation and open-field behavior of hamsters: Habituation differences

With a minimal intratrial interval, male golden hamsters spontaneously alternated significantly less often in a T-maze than females. Since there was no sex difference in choice latencies, the alternation difference could not be accounted for by longer intertrial intervals experienced by males. Instead, the difference was ascribed to faster rates of habituation to novelty in females because they showed greater between-sessions declines in open-field ambulation than males. From an analysis of rearing scores it was concluded that attempts to escape from the apparatus may have been the principal motivating influence in both the T-maze and open field.

Sex roles and nonverbal communication skills

As a step toward understanding sex differences in nonverbal decoding and encoding abilities, the hypothesis that sex-role variables are related to these communication abilities was tested. An analysis was undertaken of 11 studies on the relationship of encoding and decoding abilities to sex roles, including several masculinity and femininity scales, a measure of attitudes toward women, and a questionnaire on sex roles in the home. Although the relationships of the masculinity and femininity measures to decoding were generally weak, more masculine people tended to be better decoders. Patterns also emerged showing that the magnitude of the correlations varied with age group, sex, sex-role scale, and channel of communication. In addition, among women, those who were more liberated according to several indices were better decoders, at least of a woman stimulus person. Differences between the sexes in encoding and decoding abilities were unaffected by partialling out the masculinity and femininity measures. A hypothesis concerning the adaptive uses of nonverbal sensitivity is advanced, as well as a hypothesis concerning overall sex differences in nonverbal communication skills.Part of this research was conducted while the authors held National Science Foundation Graduate Fellowships, and was supported by a National Science Foundation Dissertation Award to the first author and by a grant from the Biomedical Research Support Program, National Institutes of Health, to The Johns Hopkins University.

Sex differences in endorsement of influence tactics and political behavior tendencies

Sex differences in the endorsement of influence tactics and political behavior tendencies were surveyed among 337 employees (176 males and 161 females). The sample was composed of managers, business owners, and professional, technical, sales, and office support workers from a variety of organizations. No significant differences were found between males and females with respect to scores on the Political Orientation Questionnaire, preference for teamwork, exchange of favors, and upward appeal. However, women were significantly less likely than men to perceive themselves as relying on charm, manipulative tactics, and personal appearance to achieve results and gain advantage. None of the sex differences could be attributed to years of job experience.     

Sex differences in proxemic behavior and personal space schemata in young children

Spatial preferences with feltboard figures, observed interpersonal distance, and sex-role identification were examined in 80 preschool children. On the feltboard measure, 4- to 5-year-olds chose generally greater interpersonal distance than younger children. Sex of stimulus figure also influenced older children's distance choices. When same-sex pair play was videotaped, older boys spent significantly more time at far distances and less time at close distances than younger boys. A positive correlation between sex-role identification, measured by the Rabban toy choice task, and feltboard figure distance was obtained for older boys only. Findings supported the notion that sex-related interpersonal spatial norms may be learned during the preschool years, particularly by boys.This study is based on a doctoral dissertation written by the author and submitted in partial fulfillment of the requirements for the Ph.D. degree at Michigan State University, 1974.     

Sex differences in student dominance behavior in female and male professors' classrooms

Measures of verbal participation and interaction among graduate students provided a comparison of male and female dominance behavior in the classroom, and measures of the contextual effect of sex of professor provided further data on the interrelatedness of sex, status, and dominance behavior. Male students were found to exhibit significantly more aggressiveness (interruptive behavior) than female students in both male and female professors' classes, although significantly more male aggressiveness occurred in female professors' classes than in male professors classes. Male students were significantly more assertive (frequency and duration of speech) in female professors' classes only. In student-to-student interaction, aggressiveness was predominantly exchanged between sexes rather than among same-sex members.The author would like to thank Julie Parks and Joanie Rubin for their help with this research.     

Sex differences in reporting sensitive behavior: A comparison of interview methods

While telephone surveys generally are considered to be comparable to in-person interviews for the collection of survey data, their utility for the acquisition of sensitive information from respondents remains in question. This paper examines the effect of interview method upon self-reports of a threatening topic—substance use—for male and female college students. It is hypothesized that males may be less likely to admit sensitive behaviors in telephone interviews, compared to face-to-face encounters, due to an interaction of a characteristic of the telephone medium (i.e., the lack of balanced exchange of identifying information between the interviewer and respondent) and aspects of the male sex role, which discourages self-revelation. Findings indicate that differences in reported use of both legal and illegal substances by interview method were greater among males than females. These gender differences in reporting behavior by survey method remained after statistical controls were applied.     

Sex differences in depression

The role of housewife has been hypothesized as the source of excess mental illness among married women as compared with married men. The present study found both housewives and working wives significantly more depressed than working husbands. Although working wives report that they do more housework than husbands, this factor was not significantly related to depression for either wives or husbands. It is suggested that the risk factors for depression, including marriage for women, may be better understood in the context of clinical theories of depression, especially the learned helplessness model.     

Sex differences in pain

Are there sex differences in pain? For experimentally delivered somatic stimuli, females have lower thresholds, greater ability to discriminate, higher pain ratings, and less tolerance of noxious stimuli than males. These differences, however, are small, exist only for certain forms of stimulation and are affected by many situational variables such as presence of disease, experimental setting, and even nutritive status. For endogenous pains, women report more multiple pains in more body regions than men. With no obvious underlying rationale, some painful diseases are more prevalent among females, others among males and, for many diseases, symptoms differ between females and males. Sex differences in attitudes exist that affect not only reporting, coping, and responses to treatment, but also measurement and treatment. So many variables are operative, however, that the most striking feature of sex differences in reported pain experience is the apparent overall lack of them. On the other hand, deduction from known biological sex differences suggests that these are powerful sex differences in the operation of pain mechanisms. First, the vaginal canal provides an additional route in women for internal trauma and invasion by pathological agents that puts them at greater risk for developing hyperalgesia in multiple body regions. Second, sex differences in temporal patterns are likely to give rise to sex differences in how pain is "learned" and stimuli are interpreted, a situation that could lead to a greater variability and wider range of pains without obvious peripheral pathology among females. Third, sex differences in the actions of sex hormones suggest pain-relevant differences in the operation of many neuroactive agents, opiate and nonopiate systems, nerve growth factor, and the sympathetic system. Thus, while inductive analysis of existing data demonstrate more similarities than differences in pain experience between females and males, deductive analysis suggests important operational sex differences in its production.     

Sex differences in self-silencing

The construct of self-silencing was proposed to account for women's greater vulnerability to developing depression. This study of 1,117 students (795 women and 322 men) explored possible explanations for the empirical finding that men self-silence to the same or greater extent than women. Analysis showed that men reported more self-silencing than women. A factor analysis confirmed the subscale structure of the Silencing the Self Scale for women and men, with relatively few departures from the originally proposed subscales. Depression and self-silencing scores were correlated positively for both men and women. The results of two multiple regressions, performed separately for men and women, showed that depressive symptomatology accounted for a significant percentage of the variance in self-silencing but that social desirability did not account for a significant increment in the variance accounted for in silencing the self. The scores on the Care as Self-sacrifice and the Divided Self subscales were intercorrelated for women, but not for men, indicating that there may be a sex difference in perception of self-silencing behavior.     

Sex differences in the effects of gonadectomy on amphetamine-induced rotational behavior in rats

The effects of gonadectomy on amphetamine-induced rotational behavior were studied in male and female rats. Different systemic doses were used to produce equivalent brain concentrations of the drug in each group, thereby controlling for sex differences in the metabolism of amphetamine. Ovariectomy of female rats significantly attenuated amphetamine-induced rotation, whereas castration of males was without effect. The results support the idea that in females, the endogenous gonadal hormones facilitate functional activity in the mesostriatal dopamine system.     

Interviewer evaluations of interviewee nonverbal behavior

Personnel representatives (N = 52) were shown one of four videotaped job interviews in which the verbal content of the 16-min interview was identical, but the interviewee's nonverbal behavior was manipulated. A “low nonverbal” interviewee was defined by minimal eye contact, low energy level, lack of affect and voice modulation, and a lack of speech fluency. The “high nonverbal” interviewee demonstrated the opposite behavior on each of these components. The subjects were asked to rate the videotaped candidates on dimensions previously identified as critical in influencing a job interviewer's decisions. Nonverbal behavior was found to have a significant effect on almost every rating made by subjects in this study. After reviewing the entire 16-min interview, 23 of the 26 subjects who saw the “high nonverbal” candidate would have invited him/her for a second interview. All 26 of the subjects who saw the “low nonverbal” candidate would not have recommended a second interview.     

Sex differences in time perception

In an experiment on discrimination of duration of auditory stimuli in the range of milliseconds 16 men and 16 women were tested. Men scored better than women in discrimination of duration as well as in required session time. These results were discussed in terms of the assumption of a neurotransmitter-related internal clock and with respect to sex differences in reaction time.
