This study was carried out to determine whether over-all heart rate and heart-rate arousal pattern ate similar for 10 male and 10 female speakers and in speaking situations with both a large as well as a small audience. Equal numbers of male and female subjects were exposed to normal-sized audiences of 21 and very small audiences of 3 during a short impromptu speech, and their heart rates monitored continuously before, during, and after speaking. With limited exception, patterns of heart-rate increment corresponded with those established in previous studies, although females conformed less closely to established patterns. Females experienced greater increment, on the average, than males, and their patterns of arousal differed in certain minor details. Before a small audience slightly greater increments were elicited than before a normal audience, and there were some indications that males and females responded differently to the two speaking situations.

This study is aimed to explore the Heart Rate Variability (HRV) response during short-term exercise by stair stepper and to compare the finding between young healthy male and female subjects. The responses were statistically analyzed by applying independent-samples t-test statistical method. The calculation of Coefficient of Variation (CoV (%)) and the slope of the linear regression is used to assess the steadiness of the HRV. Furthermore, the results also demonstrated that female subjects had greater significant p-value of RMSSD feature and significance p-value in a LF feature is greater in male. Thus, the ongoing results demonstrated that males have the sympathetic drive and females have predominant parasympathetic drive using short-term exercise by stepper. Thus, the experiment results indicate the suitability of developing rehabilitation devices in the field of Autonomic Nervous System (ANS), research, control system and rehabilitation enginering, which may help to isolate males and females.

Touching into the gender differences between males and females in expressing the use of exaggeration expressions, this study analyzes the relevant data using the LIWC tool, the HIP method, and the deficit and difference theories. This study found that in relation to the gender stereotypes, both males and females speak differently, yet also demonstrate similarities. Both the male and female subjects express emotions equally in the language production; yet, the negative emotions are dominated by the males, and the positive emotions are dominated by the females. The difference of emotion productions influences the differences in the males’ production of exaggeration expressions, such as empty adjectives, italic expressions, and hyperbole by the female subjects.

The present experiment investigated the effects of subliminal psychodynamic stimuli on anxiety as measured by heart rate. Following an anxiety-inducing task, male and female subjects were tachistoscopically shown, at their subjective thresholds, one of five subliminal stimuli, MOMMY AND I ARE ONE, DADDY AND I ARE ONE (symbiotic messages), MOMMY HAS LEFT ME (abandonment message), I AM HAPPY AND CALM (positively toned but nonsymbiotic phrase), or MYMMO NAD I REA ENO (control stimulus). It was hypothesized that men would exhibit a greater decrease in heart rate after exposure to the MOMMY stimulus than the control message. No definitive predictions were made for women. The abandonment phrase was expected to increase heart rate. A positively toned message was included to assess whether its effects would be comparable to those hypothesized for the MOMMY message. The results yielded no significant effects for stimulus or gender and so provided no support for the hypotheses.

Measurements taken from the nose are among the most important physical variables which discriminate statistically between male and female faces, yet several investigators have claimed that it is difficult to judge sex on the basis of noses presented in isolation. Previous work on the isolated nose has, however, involved the use of frontal views only, which may have obscured important physical differences between the noses of males and females. An investigation of the accuracy of judgments of the sex of isolated noses observed in frontal, profile, and three-quarter views by male and female subjects is reported. Judgment of sex was performed significantly more accurately than chance in all cases except for frontal views of female noses, where judgment was significantly less accurate than chance. Analysis of variance demonstrated a significant interaction of sex of nose and view of nose, such that male noses were identified better in frontal and in profile views, but female noses better in the three-quarter view. It is suggested that one possible reason for the seemingly contradictory role of the nose in previous studies of sex judgment is that all noses look more male in frontal views. For a nose to be perceived as female, its distinctive shape must be made available to the perceiver; this is most likely from the three-quarter view.

Research involving race as a criterion for various social choices indicates that race may rival attractiveness for the determination of dating choices. This possibility was explored in two experiments involving “desirability for a date” ratings of black and white stimulus persons who varied in attractiveness. Experiment 1 results indicated that white male and female subjects gave appreciable weight to race and attractiveness, but females gave race more weight than attractiveness, while attractiveness was given more weight than race by males. The interaction between race and attractiveness had approximately the same form for males and females: attractive black stimulus persons were lumped together with unattractive stimulus persons.Female subjects in Experiment 2, who were informed about an opportunity to date a stimulus person of their choice before seeing slides of stimulus persons, tended to discount attractiveness as a criterion for choices. None of these subjects were willing to accept an actual date. It was noted that race may be a stronger rival to attractiveness relative to the more abstract factors with which attractiveness has been compared, because race, like attractiveness, is highly concrete and visible.

Objectives. To evaluate the tooth size discrepancy and Bolton’s ratios between male and female subjects with a Class I malocclusion. Materials and Methods. The digital e-models of 100 male and 100 female 12-year-old southern Chinese children with a Class I malocclusion were selected. The mesiodistal widths from permanent first molar to the contralateral side first molar of the upper and lower dentitions were measured. Differences between the tooth size discrepancy, together with the anterior and overall Bolton’s ratios between male and female subjects, were assessed using a two-sample t-test. A paired t-test was used to determine differences between antimetric pairs of teeth within the same arch. Results. Females had statistically significant smaller teeth than males (P < 0.05) except the upper left and lower left lateral incisor and lower left and right central incisors. The mean values of anterior Bolton’s ratios for males and females were 77.04 and 77.03, respectively (P > 0.05), while the mean values of overall Bolton’s ratios of male and female are 90.48 and 90.65, respectively (P < 0.05). The clinical significant differences (Cohen’s d > 0.2) for contralateral tooth size were shown on the maxillary canines, lateral incisors, and central incisors of males; and mandibular canines and lateral incisors of females. Conclusions. Southern Chinese females presenting with Class I malocclusions have smaller mesiodistal tooth dimensions compared to males. Both males and females presented several tooth size asymmetries. There are no statistical differences in anterior and overall Bolton’s ratios between the genders.

This study assessed the differential effects of sex of pressuring confederates and perception of ability on conforming behavior of males and females. Varying male and female sources of the communication to influence subjects' views of their ability was expected to produce less conformity in females receiving the information from a male rather than a female. Data on undergraduates showed 64 females did not conform significantly more than 64 males, but male subjects conformed more in the presence of male confederates while females conformed significantly more when led to believe that males were more accurate on the task. Only the male source influencing females to believe they were superior on the task resulted in significantly less conformity in female subjects. Considering sex differences is essential due to the finding that the sexes responded to different variables present in most conformity experiments. The decrease in conformity produced in females when told by a male that females do better than males has implications for the use of male sources of communication to increase independent behavior of women.

This study investigated the effects of attitude, sex of subject, sex of invader, plane of approach, and approach trial on personal space using nonverbal, verbal, and projective measures. 10 male and 10 female subjects were approached from the front and side by a male and female invader who projected one of three attitudes: a positive, affable manner; a neutral, impartial manner; or a negative hostile manner. The factorial analysis indicated effects of sex of invader, plane of approach, and several interactions of these factors with sex of subject. These results were interpreted in terms of societal norms and potential physical and psychological threat. The observed effects of attitude were hypothesized to be a function of the different socialization processes for males and females.

Introduction: Despite cataract being a condition easily treated by surgery, it continues to be the leading cause of blindness worldwide (35.15%). In Nepal, the proportion of blindness due to cataract is much higher, with cataract accounting for 62.2% of all blindness. An effective method of decreasing this figure is by addressing the main barriers preventing people from accessing cataract surgery. Knowing that these barriers are dynamic and region-specific, our study aimed to determine the current barriers faced in Morang and Sunsari districts of Nepal. Materials and methods: Subjects were patients attending a cataract surgical camp, who had unilateral or bilateral blindness due to cataract. A survey was administered to determine the factors contributing to their delay in receiving treatment for cataract. Furthermore, the percentages of male and female subjects with bilateral blindness receiving treatment at the surgical camp were compared to the percentage of males and females with bilateral blindness due to cataract in Morang and Sunsari. Results: The main barriers for both subjects with unilateral and bilateral blindness were the inability to afford treatment and the lack of awareness that cataract is treatable. Additionally, although more women were bilaterally blind due to cataract compared to men in Morang and Sunsari, men were more likely to receive treatment compared to women. Conclusion: Policies targeted at reducing costs of surgery, increasing the awareness of cataract surgery, and specifically increasing women’s access to cataract surgery would be effective methods in decreasing the prevalence of avoidable blindness due to cataract in Morang and Sunsari.

Background: Bleeding time is a laboratory test to assess the platelet function. It is dependent on various factors like function of platelets and pathway of coagulation. Clotting time is the time required for a sample of blood to clot in vitro under standard conditions. It is known from previous studies that there is a difference in the bleeding time and clotting time among males and females. The exact reasons for such differences have been postulated, but are insufficient. Therefore the aim of this study is to study and compare the gender differences in bleeding time and clotting time in young male and female subjects. Aims and objectives: The aim of this study is to determine and compare the differences in bleeding time and clotting time in young adult male and female subjects. Materials and Methods: This study was done in the Department of Physiology, Raichur Institute of Medical Sciences, Raichur. Sixty medical students studying in first year M.B.B.S, were selected for the study, out of which thirty were males, and thirty were females. Bleeding time was determined by Duke’s method and Clotting time was determined by Wrights Capillary tube method. Data was analysed using SPSS software. Unpaired ‘t’ test was used for comparing the values. p value less than 0.05 was considered significant. Result: The mean value of bleeding time in males was found to be,127.69±51,02 and in females it was 133.28±44.30. The mean of the CT in males was 212.18±60 and in females it was found to be 257.16±61.00.The mean BT and CT was significantly higher in females as compared to the males. Conclusion: It was found that there are differences in bleeding time and time in males and females, BT and CT were statistically more in females as compared to females.
