Mirror,mirror, on the wall,who is the most masculine of them all? The Dark Triad,masculinity, and women’s mate choice

Although the Dark Triad of personality (i.e., Machiavellianism, narcissism, and psychopathy) has been researched widely, few studies have looked at women’s preferences for men who are high and low in Dark Triad. Further, it is not clear what the relationships between the Dark Triad and facial masculinity are. We investigated female preference for computer manipulated Dark Triad male faces in two on-line studies (Study 1: n = 125; Study 2: n = 1633). We found that women rated the high psychopathy and narcissistic faces the most masculine (Study 1). We also found that women showed a low preference for the high morphs in both long and short term relationships, and that preference for masculinity was correlated with a preference for narcissism (Study 2). We discuss the results in terms of male and female mating strategies.     

Men's perception of women's dance movements depends on mating context,but not men's sociosexual orientation

We investigated the influence of mating context and sociosexual orientation (interest in sex without emotional involvement) on men's perceptions of women's dance movements. One hundred men aged 18 to 33 (M = 23.5, SD = 3.5) years viewed brief videos of five “high attractive” and five “low attractive” female dancers (aged 18 to 22 years; M = 19.8, SD = 1.2) from a sample of 84 motion-captured dancers, and judged them on promiscuity and movement harmony. Additionally, half the participants judged the dancers on attractiveness as a long-term mate and the other half on attractiveness as a short-term mate. Men were more attracted to high attractive dancers than to low attractive dancers and judged them higher on attractiveness when choosing as a potential short-term mate. In addition, high attractive dancers were rated higher than low attractive dancers on promiscuity and movement harmony. Specifically, promiscuity judgments predicted men's short-term attractiveness ratings, whereas movement harmony judgments predicted long-term attractiveness ratings. Men's sociosexual orientation did not influence perceptions of female dance movements. Results are discussed with reference to trade-offs in time and energy expenditure on child rearing in men's mate preferences, corroborating the hypothesis that women's body movements inform on these qualities.     

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.     

Fighting ability influences mate value in late adolescent men

Several studies have demonstrated the relationship between handgrip strength (HGS) and fighting ability in men, which is a relevant trait for intrasexual competition to increase the probability of obtaining a mate. However, few studies have determined a relationship between fighting ability and men’s self-perceived capacity to find, attract and retain a mate. This capacity is a complex compound of several traits that evolutionary psychology has called mate value. In the present study, in a population of late adolescent men from Chile (M ± SD = 16.94 ± .89 years), we explored the relationship between fighting ability, estimated by both HGS and a self-perceived fighting ability questionnaire, and mate value, assessed with a self-perceived mate value components questionnaire. The results show a strong influence of fighting ability on mate value. This influence affects the subscales of “views from the opposite sex”, “sociality” and “relationship history”. However, we did not find an effect on the subscales of “wealth”, “parenting” or “fear to failure”. The relationship between mate value and fighting ability indicates that fighting ability is a relevant component in understanding men’s reproductive behaviour, including intrasexual competition and intersexual selection. This effect was observed in adolescents, who have less mating experience than adults.     

Indian mate preferences: Continuity,sex differences,and cultural change across a quarter of a century

Expressed mate preferences provide unique windows into evolved mating psychology. The current study used two research instruments—one ranking and one rating procedure—to examine mate preferences in India. We compared modern Indians (n = 536) with a more modest Indian sample studied a quarter of a century earlier (n = 105) to test the hypothesis that sex-specific mate preferences—as hypothesized by parental investment theory—would persist during this time period. Mate preferences for mutual attraction and love remained important and invariant over time, despite India’s history of arranged marriages. Sex differences in mate preferences for cues to fertility (youth, physical attractiveness) and resources (good financial prospects, social status) remained relatively invariant over time. Several changes in mate preferences emerged, including a greater preference for mates who are “creative and artistic,” “ambitious and industrious,” and “a good cook and housekeeper” for both sexes. Despite cultural changes in India over the past 25 years, evolved mate preferences have persisted during this time period. Discussion highlights limitations of this research.     

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.     

The relationship between mental toughness and affect intensity

Mentally tough athletes are conceptualized as being able to function effectively in stressful situations and recent research has found small to moderate correlations between mental toughness and coping. Despite this no research has thus far examined the possibility that mentally tough athletes experience less intense emotions. This paper tested the relationship between mental toughness and affect intensity to determine whether mentally tough athletes generally experienced more or less intense emotions. A sample of 112 sport performers (55 men and 57 women) aged between 18 and 51 years (M = 29.3, s = 10.3) acted as participants, and ranged from recreational to national level in a variety of sports. Mental toughness and affect intensity were found to be unrelated. This is an important finding because it suggests participants with high or low levels of mental toughness do not characteristically experience more or less intense emotions. Thus there is no evidence to suggest the ability of mentally tough athletes to remain relatively unaffected by pressure or adversity is due to lower levels of affect intensity. More research is required to understand how mentally tough athletes (in comparison to less tough athletes) maintain control and high levels of performance in stressful circumstances.     

Where birds flock to get together: The who,what, where,and why of mate searching

An understudied area of personality psychology is how personality traits might facilitate structuring of one’s environment toward goals like mating. In four studies (N = 1325), we examined (1) self-reports of where individuals go to find long-term and short-term mates, (2) how personality traits are associated with the use of these locations, and (3) how the sexes differ in their selection of mate search locations. Men were more likely than women were to use short-term (e.g., bars) than long-term (e.g., community events) niches, but did not differ in success in those niches and agreed on the nature of those niches. Slow life history traits, conscientiousness and agreeableness, were linked to preferences for long-term niches whereas, fast life history traits, narcissism and dishonesty, were linked to preferences for short-term mating niches.     

Understanding the role of gender in body image research settings: Participant gender preferences for researchers and co-participants in interviews,focus groups and interventions

Participant gender preferences for body image researchers, interventionists and focus group and intervention co-participants have been largely ignored, despite recognition that such characteristics can influence the nature and quality of data collected and intervention effects. To address this, Australian women (n = 505) and men (n = 220) completed a questionnaire about their preferences for interviewers and focus group facilitators, for teachers delivering school-based interventions, and for co-participants in these settings. Women predominantly preferred female interviewers and teachers, and mixed-sex co-participants, but most had no preference for focus group facilitators. Body dissatisfied women were more likely to prefer female researchers and single-sex co-participants. Most men did not have specific preferences, however, body dissatisfied men were more likely to report a gender preference for interviewers and teachers. Professional capabilities, personal qualities and appearance were regarded as important researcher characteristics. These findings have important implications for body image research, particularly among high-risk groups.     

Differential effects of differing intensities of acute exercise on speed and accuracy of cognition: A meta-analytical investigation

The primary purpose of this study was to examine, using meta-analytical techniques, the differential effects of differing intensities of acute exercise on speed and accuracy of cognition. Overall, exercise demonstrated a small, significant mean effect size (g = 0.14, p < 0.01) on cognition. Examination of the comparison between speed and accuracy dependent variables showed that speed accounted for most of the effect. For speed, moderate intensity exercise demonstrated a significantly larger mean effect size than those for low and high intensities. For speed of processing during moderate intensity exercise, central executive tasks showed a larger effect size than recall and alertness/attention tasks; and mean effect size for counterbalanced or randomized studies was significantly greater than for studies in which a pre-exercise followed by during or post-exercise protocol was used. There was no significant difference between mean effect sizes when testing took place post-exercise compared to during exercise for speed but accuracy studies demonstrated a significantly larger mean effect size post-exercise. It was concluded that increased arousal during moderate intensity exercise resulted in faster speed of processing. The very limited effect on accuracy may be due to the failure to choose tests which are complex enough to measure exercise-induced changes in accuracy of performance.     

Acceptance and Commitment Therapy for Problematic Internet Pornography Use: A Randomized Trial

Problematic Internet pornography use is the inability to control the use of pornography, the experience of negative cognitions or emotions regarding pornography use, and the resulting negative effects on quality of life or general functioning. This study compared a 12-session individual protocol of acceptance and commitment therapy (ACT) for problematic Internet pornography use to a waitlist control condition with 28 adult males, all but 1 of whom were members of the Church of Jesus Christ of Latter-day Saints. Measures of self-reported pornography viewing, standardized measures of compulsive sexual behavior and related cognitions, and quality of life occurred at pretreatment, posttreatment, and 3-month follow-up. Results demonstrate significant between-condition reductions in pornography viewing compared to the waitlist condition (93% reduction ACT vs. 21% waitlist). When combining all participants (N = 26), a 92% reduction was seen at posttreatment and an 86% reduction at 3-month follow-up. Complete cessation was seen in 54% of participants at posttreatment and at least a 70% reduction was seen in 93% of participants. At the 3-month follow-up assessment, 35% of participants showed complete cessation, with 74% of participants showing at least 70% reduction in viewing. Treatment suggestions and future directions are discussed.     

Social influence and physical activity in older females: Does activity preference matter?

BackgroundOlder adults appear to have different activity preferences (prefer to be active alone or with others, or show no preference). As the activity of older females is often associated with social influences (i.e., how others influence the behavior or thoughts of another), understanding how activity preference might interact with social influences becomes important.ObjectivesThis study explored whether activity preferences would moderate the social influence – physical activity relationship in older females.MethodsThe sample for this study was 102 older females with the majority (87%) classified as ‘maintainers’. Using a cross-sectional approach, participants completed questionnaires on social influences by channel (family, friends, healthcare workers) and type (modeling, compliance, conformity, obedience), activity preferences, and physical activity.ResultsMANOVA and follow-up results revealed that friends-modeling (F (2, 99) = 8.15, p < .01) and friends-compliance/conformity (F (2, 99) = 9.82, p < .01) were greater in individuals who preferred to be active with others than those who preferred to be active alone. Results from a hierarchical multiple regression examining activity preferences as a moderator were significant (R²_change = .11). For those who preferred to be active with others, friends-modeling was positively related to activity (b = 1.28). For individuals with no activity preference, activity was positively related to friends-compliance/conformity (b = 1.38) and negatively related to friends-modeling (b = ?1.56).ConclusionResults provide preliminary evidence that activity preferences appear to moderate the relationship between the influence of friends and activity in older females, especially for those who are activity maintainers.     

Contextual effects on activity profiles of domestic field hockey during competition and training

Game context is widely accepted to influence performance but most data available is ‘categorical’ and addresses performance rather than activity. This study assessed direct effects of opposition and team ranking in field hockey to establish influences on activity. One hundred and eight (n = 108) female field hockey players (age 16–39 years) participated, giving 186 competition and 48 training analyses. Team average distance (mean ± SD) observed in a mid-ranked team during competition ranged from 5949 ± 611 to 7719 ± 257 m demonstrating an opposition rank effect (Pearson’s r = .71; adjusted R² = .42). However, multiple linear regression analysis demonstrated a stronger relationship in lower ranked teams (Pearson’s r = .99; adjusted R² = .97 through 3–9). In contrast, no team rank effect was observed during randomly monitored competition where team average distance ranged from 5177 ± 444 to 7316 ± 241 m (Pearson’s r = .15 and adjusted R² = .12). In training, however, a team rank effect was observed in distance-related performance indicators where team average distance during small-sided games ranged from 5877 ± 188 to 3551 ± 193 m drill (per 70 min) with Pearson’s r = .95 and adjusted R² = .87. The presence of contextual effects has significant practical implications for team sports where the training load assumed from competition may be overestimated.     

Multidimensional perfectionism and assortative mating: A perfect date?

Assortative mating has been found regarding personality traits, personal attitudes and values, and cognitive abilities, but so far no study has investigated assortative mating regarding multidimensional perfectionism. A total of 422 participants from a non-commercial panel (mean age = 36.0 years) completed measures of self-oriented, other-oriented, and socially prescribed perfectionism and rated the attractiveness of four potential dating partners (“dates”): a self-oriented, an other-oriented, a socially prescribed, and a non-perfectionist date. Results showed that all perfectionist dates were seen as less attractive than the non-perfectionist date. This effect, however, was moderated by self-oriented and other-oriented perfectionism. Participants high in self-oriented perfectionism found all three perfectionist dates more attractive than participants low in self-oriented perfections. Participants high in other-oriented perfectionism found the self-oriented perfectionist date more attractive, and the non-perfectionist date less attractive than participants low in other-oriented perfectionism. The findings are discussed with respect to assortative mating, the social disconnection model of perfectionism, and the heritability of perfectionism.     

Mutually attracted or repulsed? Actor–partner interdependence models of Dark Triad traits and relationship outcomes

Although the Dark Triad traits – narcissism, Machiavellianism, and psychopathy – have been studied in individuals, little is known about their roles in dating relationships. Forty-five heterosexual undergraduate couples (N = 90) reported measures of the Dark Triad and relationship commitment and satisfaction. Within couples, assortative mating was slightly negative for narcissism, marginally positive for Machiavellianism, and significantly positive for psychopathy. Using actor–partner interdependence models, we explored the extent to which satisfaction mediated the direct associations between the Dark Triad and commitment. Men’s satisfaction marginally mediated the women’s Dark Triad → men’s commitment negative association. Among the three Dark Triad subscales, satisfaction marginally mediated both of the actor-effect-based psychopathy → commitment negative associations. We discuss possible implications for couples’ relationship strategies.     

Evidence of muscular adaptations within four weeks of barbell training in women

We investigated the time course of neuromuscular and hypertrophic adaptations associated with only four weeks of barbell squat and deadlift training. Forty-seven previously untrained women (mean ± SD, age = 21 ± 3 years) were randomly assigned to low volume training (n = 15), moderate volume training (n = 16), and control (n = 16) groups. The low and moderate volume training groups performed two and four sets, respectively, of five repetitions per exercise, twice a week. Testing was performed weekly, and included dual X-ray absorptiometry and vastus lateralis and rectus femoris B-mode ultrasonography. Bipolar surface electromyographic (EMG) signals were detected from the vastus lateralis and biceps femoris during isometric maximal voluntary contractions of the leg extensors. Significant increases in lean mass for the combined gynoid and leg regions for the low (+0.68 kg) and moderate volume (+0.47 kg) groups were demonstrated within three weeks. Small-to-moderate effect sizes were shown for leg lean mass, vastus lateralis thickness and pennation angle, and peak torque, but EMG amplitude was unaffected. These findings demonstrated rapid muscular adaptations in response to only eight sessions of back squat and deadlift training in women despite the absence of changes in agonist–antagonist EMG amplitude.     

Comparison of opportunities to respond and generation effect as potential causal mechanisms for incremental rehearsal with multiplication combinations

Incremental rehearsal (IR) is an intervention with demonstrated effectiveness in increasing retention of information, yet little is known about how specific intervention components contribute to the intervention's effectiveness. The purpose of this study was to further the theoretical understanding of the intervention by comparing the effects of opportunities to respond (OTR) and generation demand on retention of multiplication combinations. Using a between subject 2 × 2 factorial design, 103 4th and 5th grade students were taught seven multiplication combinations using one of four versions of IR that orthogonally varied OTR (high versus low) and generation demands (high versus low). A two-way ANOVA revealed main effects for OTR, generation demands, and an interaction of the two factors. The effect of generation demands was large (d = 1.31), whereas the overall effect of OTR was moderate (d = 0.66). Critically, the two factors interacted, with the largest learning gains observed when OTR and generation demands were both high. The results of this study suggest that generation demand is an important factor in the effectiveness of rehearsal interventions.     

Implicit need for achievement predicts attenuated cortisol responses to difficult tasks

The present research tested the hypothesis that the implicit need for achievement (n Achievement) predicts attenuated cortisol (C) responses to difficult tasks, because it represents a propensity to view difficulty as a cue to mastery reward. In two studies, n Achievement was assessed through content-coding of imaginative stories and salivary C was assessed both at baseline and post-task. In Study 1 (N = 108 US students), n Achievement predicted an attenuated C response to a one-on-one competition in the laboratory, regardless of whether participants won or lost. In Study 2 (N = 62 German students), n Achievement predicted an attenuated C response to the Trier Social Stress Test (Kirschbaum, Pirke, & Hellhammer, 1993), but not to a non-stressful control task. In Study 2 only, the attenuating effect of n Achievement was moderated by gender, with only men showing the effect. Across both studies, the average effect size of the association between n Achievement and C responses to difficult tasks was r = −.28. These findings point to a role of n Achievement in emotion regulation.     

Plurality and prevalence of sexual motivations in a sample of young francophone adults

IntroductionUnderstanding the motivations that lead to the adoption of sexual behaviors is of major interest to both the individual and public health.ObjectivesThis work (i) questions the reasons that lead students from two French universities to adopt sexual behaviors, (ii) examines the motivational similarities and differences between men and women, (iii) compare the results to data from north American subjects.MethodIn total, 657 subjects (526 women; 131 men, mean age: 22.6 years) were requested to take part in an online study investigating sexual behaviors. Reason for Having Sex Questionnaire (Meston & Buss, 2007), was used as a basis for the identification of sexual motivations.ResultOn average 53.05 different motivations led to the adoption of sexual behaviors. Significant differences of men/women were found between men and women (72% significant differences in p < 0.05) but mainly of small amplitude (d < 0.33: 58.33%). Men and women also differ in the structure of interrelations between motivations and by the role played by the different motivations. Overall, female motivational system is more sectorized and more organized than the male system, which seems more resilient (density of interrelations Men: 46.3%; women: 34.2%; distance between motivations: 5.44 vs. 3.86, p < 0.001, d = 2.07). Cultural comparisons showed significant differences of low to moderate amplitude between young adult students in France and those who come from North American universities. Gender differences in sexual motivations for sex were more marked in France than in the US.ConclusionOur results argue for a bio-psychosocial and systemic approach of sexual motivations. Theoretical, methodological and practical perspectives are envisaged.
