Sex differences and lifestyle-dependent shifts in the attunement of self-esteem to self-perceived mate value: Hints to an adaptive mechanism?

It has been suggested that self-esteem is reactive to signs of social rejection, and that this “sociometer” mechanism becomes attuned to those personal attributes that affect social acceptance by significant others. Based on evolutionary models of human mating, we predicted that self-esteem should be more attuned to self-perceived mate value in men (when compared to women) who pursue short-term mating tactics, especially if they are unsuccessful therein. In a web-based study (N = 2670), we found that mate value self-perceptions had a stronger effect on self-esteem on those who had less short-term mating success in the past. However, being in a committed relationship or parenthood reduced the impact of mate value self-perceptions. As expected, these effects were specific to men. These results are suggestive of a psychological mechanism based on adaptive sociometer attunements that could help men to choose their optimal mating tactic and might thus partly explain intrasexual differences in sociosexuality.     

Japanese Adults’ Sex Role Attitudes and Judgment Criteria Concerning Gender Equality: The Diversity of Gender Egalitarianism

This study investigated how societal conditions have influenced Japanese gender egalitarianism by analyzing sex and age group differences in attitudes towards sex roles and “gender equality judgment criteria,” the theoretical framework used to capture the diversity of gender egalitarianism. Questionnaire surveys were mailed to 1,000 randomly sampled Japanese adults in their 30s to 60s (501 valid responses). The results show that the most egalitarian sex role attitudes and greatest consideration given to gender equality judgment criteria were seen in women and in the 40s age group. This age group difference could be attributed to societal conditions during adolescence and young adulthood, including the questioning of the homemaker role during the women’s movement in Japan and the passage of laws concerning equal employment opportunities for both sexes in 1985. This article is based on the doctoral dissertation of the first author with some amendments and revisions. A part of this article was presented at the 43rd Annual Convention of the Japanese Society for Social Psychology.     

Vocabulary,Grammar, Sex,and Aging

Understanding the changes in our language abilities along the lifespan is a crucial step for understanding the aging process both in normal and in abnormal circumstances. Besides controlled experimental tasks, it is equally crucial to investigate language in unconstrained conversation. I present an information‐theoretical analysis of a corpus of dyadic conversations investigating how the richness of the vocabulary, the word‐internal structure (inflectional morphology), and the syntax of the utterances evolves as a function of the speaker's age and sex. Although vocabulary diversity increases throughout the lifetime, grammatical diversities follow a different pattern, which also differs between women and men. Women use increasingly diverse syntactic structures at least up to their late fifties, and they do not deteriorate in terms of fluency through their lifespan. However, from age 45 onward, men exhibit a decrease in the diversity of the syntactic structures they use, coupled with an increased number of speech disfluencies.     

I Can't Wait to Get Married: Gender Differences in Drive to Marry

In this study we examined a new construct—the Drive to Marry (DTM). Young single men and women (149 men and 246 women) rated their desire to get married and completed measures of their valuing of marital, parental, and occupational roles; concern about others' views of them; and feminist attitudes. We found that women had a higher DTM than did men. In both genders, DTM was predicted by the value of parental role and by concern about others' views of them. In women, DTM was also predicted by traditional attitudes toward gender roles, and there was a trend for women who valued the occupational role to have a lower DTM. Conservative women, women who valued the parental role, and women with a higher DTM were also more likely to want to use the title “Mrs.” and to adopt their husband's surname. An earlier version of this paper was presented at the annual meeting of the Midwestern Psychological Association in May 2004.     

自我监控性作为性别助长效应的干涉变量

采用双手调节器操作任务进一步验证“性别助长”假设。20个自我监控者与20个我行我素者(男女各半)分别按抵消顺序接受两种实验处理：男性观众和女性观众。结果表明,异性观众可以助长男性被试的操作速度,而削弱女性被试的操作速度;对于作业效绩也存在着同样的交互作用;自我监控性是性别助长效应的一个重要干涉变量,男自我监控者表现出明显的异性助长,女自我监控者表现出明显的异性抑制,而我行我素者没有表现出明显的观众效应。由于自我监控性对相应的异性效应有一种放大作用,可知性别助长效应的基础是以印象管理动机为主。     

The role of sex hormones and of 2D:4D ratio in individual differences in cognitive abilities

The present study aimed at investigating the role of sex hormones in individual differences in cognitive abilities. This was achieved by a combination of two methods, reflecting 2 critical periods of hormonal secretion: prenatal, based on the 2D:4D ratio, and postnatal, based on circulating hormone levels. Both methods were tested in 39 men and 41 women, who completed a battery of 6 cognitive tasks. Results showed significant sex differences on the mental rotation task, with men outperforming women. A positive correlation was found between testosterone and performance on the mental rotation task for the combined sample (men and women). A significant interaction was found between sex and estrogen on mental rotation task. Findings also revealed a significant interaction between sex and right hand 2D:4D ratio on different memory tasks. Findings regarding between- and within-sex differences in cognition are discussed in light of the organisational and activational effects of sex hormones.     

An empirical examination of sex differences in scoring preschool children's aggression

Sex differences in adults’ observations and ratings of children’s aggression was studied in a sample of preschool children (N = 89, mean age = 44.00 months, SD = 8.48). When examining the direct observations made by trained observers, male observers, relative to female observers, more frequently recorded aggressive bouts, especially of boys. On rating scales assessing aggression, trained male raters also gave higher aggressive ratings than female raters. Lastly, we compared the ratings of trained female raters and female teachers on the same scale and found no differences. Results are discussed in terms male raters’ and observers’ prior experiences in activating their experiential schemata where males’ greater experience in aggression, relative to that of females, leads them to perceive greater levels of aggression.     

He throws like a girl (but only when he's sad): emotion affects sex-decoding of biological motion displays

Gender stereotypes have been implicated in sex-typed perceptions of facial emotion. Such interpretations were recently called into question because facial cues of emotion are confounded with sexually dimorphic facial cues. Here we examine the role of visual cues and gender stereotypes in perceptions of biological motion displays, thus overcoming the morphological confounding inherent in facial displays. In four studies, participants’ judgments revealed gender stereotyping. Observers accurately perceived emotion from biological motion displays (Study 1), and this affected sex categorizations. Angry displays were overwhelmingly judged to be men; sad displays were judged to be women (Studies 2–4). Moreover, this pattern remained strong when stimuli were equated for velocity (Study 3). We argue that these results were obtained because perceivers applied gender stereotypes of emotion to infer sex category (Study 4). Implications for both vision sciences and social psychology are discussed.     

Sex differences in expressive drawing

We examined sex differences in expressive drawings produced by 105 boys and 105 girls aged 9-15 years. The drawings were classified according to the type of expressive strategy used to depict emotion (literal, content, abstract, or any combination of these), and rated according to the complexity of that strategy. A creative/divergent thinking task (figural form) was used to assess the relationship between expressive drawing and figural creativity. As predicted, girls scored higher than boys on the expressive drawing task. Specifically, girls relied less often on literal strategies alone and were more likely to combine literal expression with metaphorical (content and abstract) expression than boys. There was a linear relationship between expressive drawing and divergent thinking scores. These results are consistent with the idea that boys and girls differ in the expressive component of emotion, and suggest that these sex differences extend to the expressive drawing domain. They also suggest that divergent thinking may be involved in the ability to draw expressively.
