Partnership longevity and personality congruence in couples

Evidence of assortative mating according to personality was reported in a previous SOEP-based study (Rammstedt & Schupp, 2008). Based on population representative data of almost 7000 couples, high levels of congruence between spouses were found, which increased with marriage duration. Almost 5000 of these couples were tracked over a five-year period with personality assessed at the beginning and end of this time, which allowed us to investigate the relationship between personality congruence and marriage duration longitudinally. Using this data, we investigated (a) whether personality congruence is predictive for partnership longevity and whether congruence therefore differs between subsequently stable and unstable couples, (b) if stable couples become more congruent, and (c) if separated couples become less congruent with regard to their personality over time. The results provide initial evidence of personality congruence as a predictor for partnership longevity: the more congruent couples are in the personality domain of Openness, the more stable their partnership. In addition, we found no indications of an increase in personality congruence over time within the stable couples; within the separated couples, however, a strong decrease in congruence was detectable.     

Do assortative preferences contribute to assortative mating for adiposity?

Assortative mating for adiposity, whereby levels of adiposity in romantic partners tend to be positively correlated, has implications for population health due to the combined effects of partners' levels of adiposity on fertility and/or offspring health. Although assortative preferences for cues of adiposity, whereby leaner people are inherently more attracted to leaner individuals, have been proposed as a factor in assortative mating for adiposity, there have been no direct tests of this issue. Because of this, and because of recent work suggesting that facial cues of adiposity convey information about others' health that may be particularly important for mate preferences, we tested the contribution of assortative preferences for facial cues of adiposity to assortative mating for adiposity (assessed from body mass index, BMI) in a sample of romantic couples. Romantic partners' BMIs were positively correlated and this correlation was not due to the effects of age or relationship duration. However, although men and women with leaner partners showed stronger preferences for cues of low levels of adiposity, controlling for these preferences did not weaken the correlation between partners' BMIs. Indeed, own BMI and preferences were uncorrelated. These results suggest that assortative preferences for facial cues of adiposity contribute little (if at all) to assortative mating for adiposity.     

教学心理学情感维度上的一种教材处理策略——心理匹配

在教学心理学领域中,人们往往习惯于从认知维度探索教材的优化处理策略,缺乏情感维度上的相应研究。奥苏贝尔虽提出意义学习的两个内在先决条件：一是学习者有同化新材料的认知结构;二是学习者有意义学习的心向．但他本人也仅从影响学生认知结构的角度,提出教材的认知处理策略──先行组织者策略．而未从影响学生心向的角度．提出教材的情感处理策略。鉴此,本文从情感维度上提出教材处理的心理匹配策略．以冀与认知策略一起共同优化处理教材、呈现教学内容环节,并阐明心理匹配策略的内涵、机制、作用和种类。     

拿破仑情结的进化：相对身高劣势和求偶动机对男性冒险行为的影响

研究以性选择理论为基础, 探讨了与同性竞争者的相对身高劣势和求偶动机对男性冒险行为的影响。4个研究一致显示, 与同性竞争者存在的身高劣势会导致男性提高自身冒险性; 且高求偶动机水平的男性, 会更多地表现出这种补偿性行为。这些结果提示, 拿破仑情结具有进化的基础, 男性在自身身高与竞争者相比处于劣势时, 采用冒险行为进行补偿是男性用以解决性内竞争和性间竞争问题的一种适应器。     

Good Enough for an Affair. Self‐Enhancement of Attractiveness,Interest in Potential Mates and Popularity as a Mate

Using data from the Berlin Speed Dating Study, we tested rival hypotheses concerning the effects of self‐enhancement of attractiveness on dating outcomes. Three hundred eighty‐two participants took part in one of the 17 speed‐dating sessions. After each speed‐dating interaction, participants indicated how interesting they found the respective person as a long‐term and short‐term partner. Using social relations analyses, we computed perceiver effects (being more or less choosy) and target effects (being rated as more or less interesting) of long‐term and short‐term partner ratings. Self‐enhancement was operationalized as the discrepancy between self‐rated attractiveness and four components of actual attractiveness (observer‐rated facial and vocal attractiveness, height and body mass index). Results indicated that self‐enhancers were less choosy with respect to their interest for short‐term partners, which was especially true for men, but more choosy with respect to long‐term partners. With regard to popularity as a mate, potential partners indicated that they found self‐enhancers more interesting as short‐term partners but not as long‐term partners. As self‐enhancement is a key component of narcissism, these results are consistent with findings that narcissists perceive many sexual affairs as an achievement, while preferring selected ‘trophy’ long‐term partners, and narcissists have a charming appeal for short‐term, but not lasting, social relationships.

女性食物选择的演化视角：基于性选择过程的理论探讨

性选择在人类心理、行为等表型的演化过程中扮演了重要角色,但其对女性食物选择的影响却相对较少被关注。性选择塑造了男女不同的择偶策略,男性择偶时对女性外在吸引力的关注使得女性更加重视身材等外在吸引力信息。而女性身材与饮食的密切联系,进一步提示性选择过程应该会对女性的食物选择产生影响。以之为基础,梳理求偶动机激活可能引发的女性食物选择的变化,以及女性生理期不同阶段在食物选择上的变异,有助于了解性选择过程对女性食物选择的影响。未来研究中,进一步从行为、激素、脑等不同层面剖析对应影响及涉及机制,对该领域的长远发展有重要意义。     

The dark triad: Facilitating a short‐term mating strategy in men

This survey (N = 224) found that characteristics collectively known as the Dark Triad (i.e. narcissism, psychopathy and Machiavellianism) were correlated with various dimensions of short‐term mating but not long‐term mating. The link between the Dark Triad and short‐term mating was stronger for men than for women. The Dark Triad partially mediated the sex difference in short‐term mating behaviour. Findings are consistent with a view that the Dark Triad facilitates an exploitative, short‐term mating strategy in men. Possible implications, including that Dark Triad traits represent a bundle of individual differences that promote a reproductively adaptive strategy are discussed. Findings are discussed in the broad context of how an evolutionary approach to personality psychology can enhance our understanding of individual differences.

Countries with fewer males have more violent crime: marriage markets and mating aggression

Violent crimes (murders, rapes, and assaults) are substantially higher in countries with a relative scarcity of men according to research using INTERPOL data [Barber, 2000a]. This is a paradox given that males are more criminally violent and likely reflects increased direct mating competition. The present research sought to confirm and extend Barber's [2000a] finding, using murder data from the United Nations and homicides from World Health Organization that are of higher quality than the INTERPOL data, and using more rigorous controls. In addition to level of economic development, control variables included, income inequality, urbanization, population density, the number of police, and whether the country was a major center of illegal drug trafficking. Regression analyses with all controls found that killings in both data sets increased with declines in the male proportion of the population. The findings are discussed in terms of direct reproductive competition and alternative explanations are considered.
