Social representations associated with men and women drivers among French adolescents and adults. Effects of the perceiver’s age,sex, and socioeconomic status

The aim of this study was to investigate the specific contents of the social representations (SR) associated with men and women drivers and examine the effects of the social insertions of individuals (i.e., age, sex and socio-economic status) on the content and structure of these SR. A preliminary study with 414 French participants identified thematic content associated with men and women drivers using the verbal association method. Based on these themes, 833 French participants, equally distributed by age group (from 12 to 50 years-old and over), sex and socioeconomic status (SES), were asked to answer a questionnaire on men (N = 422) or women (N = 411) drivers. The results show that each of these SR is organized around three factors: incompetence, prudence and lack of self-control for women drivers; carelessness, skills and self-control for men drivers. In-group favoritism bias can be noted in both groups as male participants, more than female ones, rated men drivers as having self-control and women drivers as lacking self-control, whereas female participants, more than male ones, perceived men drivers as careless and women drivers as prudent. Despite this phenomenon, more male respondents than female ones in all age groups seemed to believe that women are not competent at driving, whereas both sexes seem to agree that men have good driving skills. Among most age groups, three characteristics associated with men drivers (confidence, speed and pleasure of driving) and four characteristics associated with female drivers (caution, civil, compliance with rules and vigilance) emerged as central in the SR. The SR associated with men drivers appeared to be stable and shared across age groups, whereas the SR associated with women drivers appeared more mixed, heterogeneous and unstable with age. Female participants with higher SES consider women drivers as more incompetent, less prudent and more lacking self-control than female participants with lower SES.     

Occupational segregation and psychological gender differences: How empathizing and systemizing help explain the distribution of men and women into (some) occupations

The proportion of men and women workers varies among occupation types. There are several factors that may contribute to occupational segregation by gender. Using a large U.S. sample (n = 2149), we examine the extent to which occupational segregation can be attributed to gender differences in empathizing and systematizing: Psychological dimensions which theorists argue represent meaningful differences between men and women. Of the eight occupational categories for which employee gender and occupation type were associated at the p < .01 level, four of these – Construction, Professional/Scientific/Technical fields, Management, and Education – were partially mediated by systemizing and/or empathizing scores, which typically accounted for 10–20% of the observed gender differences. For other areas, like Health, gender differences were not mediated by either measure.     

The stability and change of malaise scores over 27 years: Findings from a nationally representative sample

This study investigates the stability and change of malaise scores over a period of 27 years taking account of socio-demographic variables, childhood intelligence and behavioural problems. 6822 cohort members had the complete data on Malaise measured at 23, 33, 42, and 50 years. T-tests showed that there were significant changes of malaise mean scores over the 27 years: malaise scores decreased significantly from 23 to 33 years, but increased significantly from 33 to 42 years, and there were no significant change between 42 and 50 years. The trend showed a similar pattern for men and women, though women scored significantly higher than men on the measure at every time point. Correlational analysis showed that over 27 years malaise scores ranged from r = .41 to r = .52, indicating the relative stability. Malaise was significantly and inversely associated with childhood intelligence and behavioural problems. It was also significantly associated with education in the expected direction. Regression analysis showed that previous malaise scores were significant predictors of the later ones, and the strength of the predictive power decreased over time. Limitations were considered.     

Machiavellianism and sexual behavior: Motivations,deception and infidelity

The current study investigated the influence of Machiavellianism, a personality trait characterized by a manipulative interpersonal style and willingness to exploit others (Christie & Geis, 1970), on three areas of sexual behavior. Men (N = 90) and women (N = 192) aged 18–81 years (M = 25.82, SD = 9.85) completed the Mach IV (Christie & Geis, 1970), YSEX Questionnaire (Meston & Buss, 2007), Sexual Deception Scale (Marelich, Lundquist, Painter, & Mechanic, 2008) and Intentions Towards Infidelity Scale (Jones, Olderbak, & Figueredo, 2011). Those with high levels of Machiavellianism were more likely to engage in sexual behavior for physical reasons, goal attainment and insecurity. In particular, Machiavellian men and women endorsed stress reduction, experience seeking, resources, social status, revenge, utilitarian reasons, boosting self-esteem, duty/pressure, and mate guarding as motivations for sexual behavior. Machiavellianism was also a significant predictor of each form of sexual deception investigated (blatant lying, self-serving and avoiding confrontation) and intentions to engage in infidelity. Sex did not moderate the influence of Machiavellianism on sexual behavior.     

Height preferences in humans may not be universal: Evidence from the Datoga people of Tanzania

Many studies in Western societies have shown that women prefer relatively taller men as potential partners, whereas men prefer women who are slightly shorter than themselves. Here, we discuss possible limitations of previous results within the context of the stimuli used (i.e., differences in the perceived body size of female silhouettes). Our results show that, at least in a Polish sample (N = 231), modified stimuli did not essentially change the observed male-taller preferences. In contrast, we report height preferences in a traditional ethnic group, the Datoga people from Tanzania (N = 107), in which men and women preferred extreme sexual dimorphism in stature (SDS) sets (i.e., men and women chose women much taller or much shorter than themselves). Thus, our data do not accord with the suggestion of a universal preference for taller men, but rather suggests that height preferences may be influenced by cultural, environmental, and ecological conditions.     

Social status,cognitive ability,and educational attainment as predictors of liberal social attitudes and political trust

We examined the prospective associations between family socio-economic background, childhood intelligence (g) at age 11, educational and occupational attainment, and social attitudes at age 33 in a large (N = 8804), representative sample of the British population born in 1958. Structural equation Modeling identified a latent trait of ‘liberal social attitudes’ underlying attitude factors that are antiracist, socially liberal, and in support of gender equality. Another attitude factor—‘political trust’—was relatively independent from the latent attitude trait and has somewhat different pathways in relation to the other variables included in the analysis. There was a direct association between higher g at age 11 and more liberal social attitudes and political trust at age 33. For both men and women the association between g and liberal social attitudes was partly mediated via educational qualifications, and to a much lesser extent via adult occupational attainment. For women the association between g and political trust was partly mediated through both educational qualification and occupational attainment, and for men it was mediated mainly via occupational attainment. Men and women who had higher educational qualifications and higher occupational status tend to be more socially liberal and more trusting of the democratic political system. In terms of socio-economic background, people from less privileged families showed less political trust, but did not differ much in liberal social attitudes from those born into relatively more privileged circumstances. This study shows that social background, cognitive ability, education, and own social status influence perceptions of society.     

Personality traits and body mass index in Asian populations

Research on personality and adiposity has focused primarily on Western samples; less is known about the personality correlates of BMI in Asian populations. We examined the association between personality and body mass index (BMI) among community-dwelling Japanese adults (N = 380), Chinese adolescents (N = 5882), and a meta-analysis inclusive of a published Korean sample (total N = 10,304). In the new samples and meta-analysis, Extraversion and Agreeableness were associated with higher BMI among men. In contrast to what is often found in Western samples, Conscientiousness was mostly unrelated to adiposity. These findings link pro-social tendencies to overweight among Asian men; Conscientiousness may be less relevant for BMI in Eastern societies with a low prevalence of obesity and strong social norms for eating but not thinness.     

Cross-sectional age differences in the HEXACO personality: Results from a Japanese sample

Little research has been conducted on personality development in non-Western countries. The present study investigated age differences in personality in Japanese middle adults (N = 2000; M = 40.94 years; SD = 5.35, range 30–49; 1000 women). After controlling for educational level, annual income, marital status, and gender, it was found that the level of Emotionality was negatively associated with age. Honesty–Humility, on the other hand, was positively associated with age. However, Extraversion, Agreeableness, Conscientiousness, and Openness were not associated with the participant age. These findings suggest that trends in personality development may differ slightly between Western and non-Western countries.     

Meta-analytic evidence for higher implicit affiliation and intimacy motivation scores in women,compared to men

We used meta-analysis to test for gender differences in implicit needs for affiliation/intimacy, assessed via story-coding methods. We included thirty-three effect sizes from 26 publications and 2 unpublished studies, covering a total of 5962 research participants (58% female). Across studies, women scored higher than men in measures of implicit affiliation motivation (d¹ = 0.45, 95%CI = [0.37; 0.53]). This finding was not moderated by the coding system used, gender congruence of the picture cues presented, or correction for protocol length. Men and women did not differ in their implicit needs for power (N = 2493, k = 15, d¹ = −0.19, 95%CI = [−0.44; 0.05]) or achievement (N = 2235, k = 13, d¹ = 0.14, 95%CI = [−0.03; 0.30]).     

More than just body weight: The role of body image in psychological and physical functioning

The current study examined BMI and body image dissatisfaction as predictors of physical and mental health-related quality of life (HRQL) and psychosocial functioning in a sample of 414 undergraduate students (mean age = 21.5, SD = 4.9; mean BMI = 23.6, SD = 5.2). In men and women, higher BMI was correlated with body image dissatisfaction and physical HRQL, but not with any measures of psychosocial functioning, whereas higher body image dissatisfaction was associated with poorer physical HRQL and psychosocial functioning. Furthermore, body image dissatisfaction was observed to mediate the relationship between BMI and physical HRQL in men and women. Interestingly, in this model, higher BMI predicted increased self-esteem. These findings suggest that body image dissatisfaction may be an important target for health interventions.     

Older sisters and younger brothers: The impact of siblings on preference for competition

Psychology studies have long argued the possibility that sibling structure, such as birth order and the sex of siblings, shapes one’s personality traits. One of the core issues involved is that of who rates subjects’ personality traits in studies. The present studies (N = 135 in Study 1, N = 232 in Study 2) surpassed the examinations performed in previous studies by obtaining information regarding one of the key personality traits, preference for competition, using a framework developed via experimental economics rather than subjective ratings. Despite the fact that the two studies involved different types of task, we consistently observed that older sisters exerted a significant impact on their younger siblings in both studies. In particular, having an older sister was negatively associated with men’s competitive preferences. We also obtained suggestive evidence that having an older sister was positively associated with women’s competitive preferences. Our results support sibling hypotheses from the perspective of experimental economics.     

Personality,intelligence and proof-reading

Two studies sought to determine personality and cognitive ability correlates of proof-reading. In both studies candidates were given 5 min to identify up to 55 errors in a 920 word, two page document. In Study 1, which tested 240 school children, fluid intelligence (as measured by the Baddeley Reasoning Test) was the highest correlate of proof-reading (r = .30). Eleven percent of the variance in total attempted scores was accounted for by intelligence, Introversion and low Conscientiousness. In the second study 70 undergraduates completed the same proof-reading test along with two intelligence tests (Baddeley Reasoning Test; Wonderlic Personnel Test) and a more robust personality measure (NEO-FFI). Proof-reading was correlated with both intelligence tests (Baddeley r = .45; Wonderlic r = .40). More of the variance was accounted for in the total attempted-score of errors than for a correct errors-detected score. When the two intelligence and five personality trait scores were regressed on to the proof-reading test score over a quarter of the variance (Adj R² = .28) was accounted for, but only the Baddeley test was a significant predictor (Beta = .39).     

Do sex differences in a faceted model of fluid and crystallized intelligence depend on the method applied?

Recently, different methodological approaches have been discussed as an explanation for inconsistencies in studies investigating sex differences in different intelligences. The present study investigates sex differences in manifest sum scores, factor score estimates, and latent verbal, numerical, figural intelligence, as well as fluid and crystallized intelligence as measured by the German Intelligence-Structure-Test 2000-R (IST 2000-R; Liepmann, Beauducel, Brocke, & Amthauer, 2007). The not population-representative sample consisted of 977 German 11th and 12th graders enrolled in a “Gymnasium” (551 female; mean age: M = 16.70; SD = 0.65) who completed the IST 2000-R. Sex differences in fluid and crystallized intelligence were not influenced by the method applied with men performing better than women. However, extent and direction of sex differences in verbal, numerical, and figural intelligence differed by the method applied. Whereas there was a male advantage in all three factors measured as manifest sum scores, women performed better in verbal intelligence as measured by factor scores or as latent variables. Effect sizes of sex differences in numerical and figural intelligence were also greatly reduced when applying the latter two methods. Results are discussed with regard to their theoretical and practical implications.     

Self-objectification and depressive symptoms: Does their association vary among Asian American and White American men and women?

Objectification Theory (Fredrickson & Roberts, 1997) posits that viewing one's body as an object – i.e., self-objectification – increases depressive symptomatology. Though a handful of studies to date have found self-objectification and depressive symptoms correlated among White American women, few studies have examined whether this finding generalizes to other social groups. We examine whether self-objectification and depressive symptoms are associated among Asian Americans and White Americans in a college sample of women and men (N = 169). Self-objectification and depressive symptoms were positively associated among White American women but not among White American men or Asian American men or women. These data suggest the parameters of Objectification Theory are circumscribed by both race/ethnicity and gender and self-objectification may put White women, in particular, at risk for depressive symptoms.     

Childhood IQ and in-service mortality in Scottish Army personnel during World War II

The Scottish Mental Survey of 1932 (SMS1932) provides a record of intelligence test scores for almost a complete year-of-birth group of children born in 1921. By linking UK Army personnel records, the Scottish National War Memorial data, and the SMS1932 dataset it was possible to examine the effect of childhood intelligence scores on wartime military service mortality in males. There were 491 matches between World War II (WWII) Scottish Army fatalities and the SMS1932 database; 470 (96%) had an age 11 mental ability score recorded. The mean (S.D.) age 11 IQ score of those who died on active service in WWII was 100.78 (15.56), compared with 97.42 (14.87) for male Army survivors (p < 0.0001; Cohen's d = 0.22). Men who took part in the SMS1932 and who were not found in the Army database had a higher mean score (100.45, S.D. =14.97) than those men who had been in the Army, regardless of whether they died or survived (mean IQ = 97.66, S.D. = 14.94; p < 0.0001; Cohen's d = 0.19). Male soldiers with a higher childhood IQ had a slightly increased risk of dying during active service in WWII. Men who did not join the Army had a higher IQ than men who did. Further research in this area should consider naval and air force personnel records in order to examine more fully the complex relationship between IQ and survival expectancy during active service in WWII.     

Intelligence,social class of origin,childhood behavior disturbance and education as predictors of status attainment in midlife in men: The Aberdeen Children of the 1950s study

In a birth cohort of 6281 men from Aberdeen, Scotland, social class of origin, childhood intelligence, childhood behavior disturbance and education were examined as predictors of status attainment in midlife (46 to 51 years). Social class of origin, intelligence and behavior disturbance were conceptualized as correlated predictors, whose effects were hypothesized to be partially mediated by educational qualifications. A structural equation model using Full Information Maximum Likelihood estimation confirmed that education had the strongest direct effect on status attainment at midlife. Furthermore, education partially mediated the effects of social class of origin and childhood intelligence, and fully mediated the effects of behavior disturbance on status attainment. Social class of origin, childhood intelligence and behavior disturbance were strongly inter-correlated. After controlling for these associations, educational and social status attainments were influenced to a considerably greater extent by childhood intelligence than by social class of origin.     

Preparing for uncertain careers: How youth deal with growing occupational uncertainties before the education-to-work transition

Recent changes in labor market and working conditions have rendered youth's education-to-work transitions and career prospects more uncertain. This study investigated how youth, while still in education or training, deal with perceived growing occupational uncertainties in terms of goal engagement (i.e., investing active effort in goal pursuit; surmounting obstacles) and goal disengagement (i.e., distancing from unattainable goals; protecting the self against failure experiences). Analyses with two closely matched samples of youth aged 16–25 years from Germany (N = 529) and Poland (N = 530) revealed high levels of goal engagement and a clear preference of engagement over disengagement. Whereas levels of engagement were comparable across countries, disengagement was considerably higher in Polish youth. Regarding the sources of individual differences in engagement and disengagement, sociodemographic factors had very limited effects in both countries. Compared to sociodemographic factors, the level of perceived growing occupational uncertainties, and especially youth's primary and secondary appraisals thereof, were more strongly and consistently associated with engagement and disengagement, especially in Germany, pointing to the prominence of perceptions and appraisals in shaping youth's responses to growing occupational uncertainties. We offer cultural and economic explanations for these findings and discuss implications for interventions aimed at fostering youth's engagement in preparing for their future careers under today's uncertain conditions.     

Intelligence and semen quality are positively correlated

Human cognitive abilities inter-correlate to form a positive matrix, from which a large first factor, called ‘Spearman's g’ or general intelligence, can be extracted. General intelligence itself is correlated with many important health outcomes including cardio-vascular function and longevity. However, the important evolutionary question of whether intelligence is a fitness-related trait has not been tested directly, let alone answered. If the correlations among cognitive abilities are part of a larger matrix of positive associations among fitness-related traits, then intelligence ought to correlate with seemingly unrelated traits that affect fitness—such as semen quality. We found significant positive correlations between intelligence and 3 key indices of semen quality: log sperm concentration (r = .15, p = .002), log sperm count (r = .19, p < .001), and sperm motility (r = .14, p = .002) in a large sample of US Army Veterans. None was mediated by age, body mass index, days of sexual abstinence, service in Vietnam, or use of alcohol, tobacco, marijuana, or hard drugs. These results suggest that a phenotype-wide fitness factor may contribute to the association between intelligence and health. Clarifying whether a fitness factor exists is important theoretically for understanding the genomic architecture of fitness-related traits, and practically for understanding patterns of human physical and psychological health.
