Positive Reciprocity

Although cooperative mating strategies have been observed in other species, the extent to which men and women act to facilitate the mating success of others has been under-researched, especially among unrelated individuals. The present study addressed this gap in knowledge by exploring potential sex differences and individual differences in attitudes toward facilitating and preventing friends’ mating among 256 heterosexual undergraduate men and women. Results showed that women were more likely than men to express attitudes toward preventing the sexuality of friends, whereas no sex difference existed in facilitative mating. For both men and women, positive reciprocity beliefs and high self-perceived mate-value predicted positive attitudes toward facilitative mating. Among women, preventive mating was predicted by low sociosexuality and high intrasexual (within-sex) competitiveness.

T Score

Individual differences in time production should indicate differences in the rate of functioning of an internal clock, assuming the existence of such a clock. And sex differences in time production should reflect a difference in the rate of functioning of that clock between men and women. One way of approaching the data is to compute individual regressions of produced duration (P) on target duration (T), after log transformation, and to derive estimates for the intercept and the slope. One could investigate a sex difference by comparing these estimates for men and women; one could also contrast them by looking at mean log(P). Using such indices, we found a sex difference in time production, female participants having a relatively faster internal clock, making shorter time productions, and having a smaller exponent. The question is whether a sex difference in time production would be found using other methods for analyzing the data: (1) the P/T ratio; (2) an absolute discrepancy (|P-T|) score; and (3) an absolute error (|P-T|/T) score. For the P/T ratio, female participants have a lower mean ratio in comparison to the male participants. In contrast, the |P-T| and |P-T|/T indices seem to be seriously compromised by wide individual differences.

Age And Sex

Buss and Schmitt's sexual strategies theory (1993) suggests that short-term mating represents a larger component of men's than women's mating strategies. Assuming this sex difference there is potential for conflict. Symons argued that, because men are more interested in copulation than women, this gives women greater power in establishing conditions (short- vs long-term) under which copulation takes place. The result is that the conflict in sexual strategies is resolved in favor of women's relatively greater interest in long-term sexual strategies. This research tested the hypothesis that across ages men would decrease in desire to employ short-term mating strategies in favor of long-term mating strategies. Specifically, in Study I, men and women in their teens, twenties, and thirties or older were given a measure of desire for a committed relationship. It was predicted that women, regardless of age, would score high on desire for a committed relationship. In contrast, teenage boys would score low on desire for a committed relationship while men in their thirties or older would score as high as the women. In Study II both sexes in their teens, twenties, and thirties or older were given measures of desire for promiscuous sex. It was predicted that the women, regardless of age, would score low on desire for promiscuous sex. In contrast, teenage boys would score high on desire for promiscuous sex while men in their thirties or older would score as low as the women. Support was found for both predictions.

The Relationship

Summary: The Gudjonsson Compliance Scale (GCS), the COPE Scale, and the Rosenberg Self-Esteem Scale were administered to 212 men and 212 women. Multiple regression of the test scores showed that low self-esteem and denial coping were the best predictors of compliance in both men and women. Significant sex differences emerged on all three scales, with women having lower self-esteem than men, being more compliant, and using different coping strategies when confronted with a stressful situation. The sex difference in compliance was mediated by differences in self-esteem between men and women.

Present purposes were to examine the characteristics of controlled force exertion in 28 developmentally delayed young people (14 men, 14 women), and sex differences compared to 28 normal young students (14 men, 14 women). The subjects matched their submaximal grip strength to changing demand values displayed in a bar chart on the display of a personal computer. The total sum of the differences between the demand value and grip exertion value for 25 sec. was used as an evaluation parameter for the test. The controlled force exertion was significantly poorer for the developmentally delayed group than for controls, and there were large individual differences. The developmentally delayed men scored poorer than women in coordination. Like the controls, the means between trials did not decrease significantly. For these developmentally delayed subjects, performance did not improve after only a few trials. The controlled force-exertion test is useful as a voluntary movement-function test for developmentally delayed subjects.

It is hypothesized that Rotter's I-E variable mediates individual differences in supernatural and superstitious beliefs, with externals exhibiting more positive attitudes toward such phenomena. An approximately equal number of male and female introductory psychology students were selected as externals ( N = 20) and internals ( N = 23) from upper and lower quartiles of the Rotter I-E scale. All Ss were administered an attitude questionnaire assessing beliefs toward several paranormal, occult, and pseudoscientific phenomena. Analysis via a 2 × 2 (I-E Control × Sex) analysis of variance strongly confirmed the hypothesis ( p < .01). Although not predicted, females, regardless of I-E status, were much more favorably disposed toward such phenomena than males ( p < .01). Differences in more general attitudes toward both religion and science are suggested as mediating the over-all I-E and sex differences.

The sex difference in marathon running is increased with lower participation of women than men, but whether this occurs for ultramarathon running is not known. The study purpose was to determine whether the sex difference in performance widens among lower-placed runners and the association between the sex difference in running speed and participation rates. The top-10 ultramarathon running times, age at performance date, and the number of men and women finishers were analyzed from 20 races (45–160 km) in the US Track and Field Ultra Running Grand Prix. Men were faster than women for all events (18.7% ± 5.8%, P < .001). The sex difference in speed was the least for 100 km (14.9% ± 4.2%) and greatest for 45–50 km (19.3% ± 5.8%). The top-10 men were younger than the top-10 women (37.7 ± 3.2 and 39.0 ± 3.1 y, respectively, P < .001). The sex difference in speed increased with finishing place (1st place 15.6% ± 6.6% vs 10th 20.8% ± 5.6%, P < .001). Association analysis showed that the sex difference in speed was largest when there were fewer women than men finishers in a race; the strength of the association was greatest for the 80-km distance and least for the 160-km. Lower participation rates of women than men in the lower-distance ultramarathons and less depth among lower-placed women runners inflate the sex difference in ultramarathon performance.

Ratings of the self and of an hypothetical well-adjusted man and woman on the Divided Self and Care as Self-sacrifice subscales of the Silencing the Self Scale were obtained for samples of men and women in the USA and Greece. Factor analysis confirmed the items' assignment to subscales for each of the three sets of ratings. Generally, Greeks scored higher than Americans on both subscales. While men usually scored higher than women on the Care subscale in both countries, they only did so in Greece for the Divided Self. Women had greater discrepancies than men between their self and well-adjusted same-sex rating on both subscales in each country, with this sex difference being greater in Greece than the USA and greater on the Care subscale in both countries.

Abstract Previous works have shown that sociosexuality may affect mate choice and correspond to partners’ mate value (MV). However, there is a lack of studies that directly show how a difference between both partners’ mate values (MVD) relates to reproductive strategies. In this study we investigated a possible link between self-reported measures of individual differences in human mating strategies (SOI-R) and self-perceived mate value asymmetry (difference between partners’ MV) in heterosexual romantic relationships. Two hundred forty-nine heterosexual participants (all in romantic relationships) completed an online questionnaire. Their sociosexuality was measured using Revised Sociosexual Orientation Inventory (SOI-R) (Penke and Asendorpf 2008). The assessment of the participant’s and his/her partner’s MVs were obtained using the MV measure by Graham-Kevan and Archer (2009). MVD was calculated by deducting the assessment of partner’s MV and MV self-assessment. Our results revealed that in men, with the increase of the discrepancy in mate value in favor of their female partners, male global sociosexuality and sociosexual desire decreased. In contrast, in women no significant correlations were found. We propose several possible explanations, based on evolutionary psychology, discussing our results within the context of potential benefits for reproductive success in both sexes due to the lower male sociosexuality

The purpose of the present study was to examine sex differences in preferences for coffee sweetness. The participants were 59 Japanese undergraduate students. Men preferred sweeter coffee than women, while both men and women showed almost the same preference for acidic beverage sweetness. The sex difference in preferences for coffee sweetness may be related to coffee-drinking habits.

The Difference

Abstract. Previous results on the prosociality of men and women in social dilemmas are mixed. Studies find more prosocial behavior for men and women; and a meta-analysis ( Balliet et al., 2011 ) reports an overall null effect. Including samples ( N = 1,903) from 10 countries that vary concerning gender inequality (e.g., China, Colombia, Sweden), we investigated sex differences in social dilemmas and drivers of these potential differences. We found that men behaved more prosocially, in that they transferred more of their endowment to their interaction partner. This sex difference was descriptively observed for all countries and was partially mediated by differences in risk but not social preferences. Gender inequality did not predict the difference in magnitude of sex differences between countries.
