Sexually dimorphic preference for altruism in the opposite sex according to recipient

Sexual selection may affect human altruistic behaviour. Evolutionary psychology predicts that human mate preference reflects sexual selection. We investigated sex differences in preference for opposite‐sex altruism according to recipient because the reasons for altruistic behaviour differ according to the relationship between actor and recipient. We employed the Self‐Report Altruism Scale Distinguished by the Recipient, which was newly developed to evaluate altruism among Japanese undergraduates. We asked participants to evaluate preferences for each item based on the recipient of the altruistic behaviour (family members, friends or acquaintances, and strangers). Preference for opposite‐sex altruism differed according to recipient, gender of the participant, and relationship type, and several significant interactions were observed among these factors. We suggest that whereas women use a potential partner's altruism towards strangers as a costly signal of their resource‐holding potential when choosing a mate, they consider altruism towards family when they are in a long‐term relationship to ensure that resources are not allocated to non‐relatives.     

The synergistic effect of prosociality and physical attractiveness on mate desirability

Mate selection requires a prioritization and joint evaluation of different traits present or absent in potential mates. Herein, we focus on two such traits – physical attractiveness and prosociality – and examine how they jointly shape impressions of overall desirability. We report on two related experiments which make use of an innovative methodology combining large samples of raters and target persons (i.e., stimuli) and information on targets’ behaviour in economic games representing altruistic behaviour (Experiment 1) and trustworthiness (Experiment 2), two important facets of prosociality. In accordance with predictions derived from a cognitive perspective on mate choice and sexual strategies theory, the results show that the impact of being prosocial on an individual's overall desirability was increased further by them also being physically attractive, but only in long-term mating contexts. Furthermore, we show that men's mate preferences for certain prosocial traits (i.e., trustworthiness) were more context-dependent than women's due to differential evolutionary pressures for ancestral men and women.     

A Comparison of the Neurotic Tendencies of Students of Different Racial Ancestry in Hawaii

ABSTRACT

Research has shown that altruism plays a role in mate choice, and recent studies suggest it is most important for long-term relationships. This study examined whether altruism is preferred for long-term relationships for both males and females. This was achieved using two versions of the Mate Preferences Towards Altruistic Traits (MPAT) scale that assessed preferences for short-term and long-term relationships. Both males and females significantly preferred altruistic mates for long-term relationships, and the size of this preference was greater than for other traits in mate choice. This provides support for previous findings that state that altruism conveys information about an individual's partner/parenting qualities or good character.     

Do humans prefer altruistic mates? Testing a link between sexual selection and altruism towards non‐relatives

Humans are often seen as unusual in displaying altruistic behaviour towards non‐relatives. Here we outline and test a hypothesis that human altruistic traits evolved as a result of sexual selection. We develop a psychometric scale to measure mate preference towards altruistic traits (the MPAT scale). We then seek evidence of whether mate choice on the basis of altruistic traits is present and find it in one study (N=170 couples). We also predict that a stronger female MPAT, as measured by responses to the MPAT scale, will be expressed – a result found in all three studies (Ns=380, 340, and 398). Both sets of results are consistent with the hypothesized link between human altruism towards non‐relatives and sexual selection.     

How Alluring Are Dark Personalities? The Dark Triad and Attractiveness in Speed Dating

Dark Triad traits (narcissism, psychopathy, and Machiavellianism) are linked to the pursuit of short‐term mating strategies, but they may have differential effects on actual mating success in naturalistic scenarios: Narcissism may be a facilitator for men's short‐term mating success, while Machiavellianism and psychopathy may be detrimental. To date, little is known about the attractiveness of Dark Triad traits in women. In a speed‐dating study, we assessed participants' Dark Triad traits, Big Five personality traits, and physical attractiveness in N = 90 heterosexual individuals (46 women and 44 men). Each participant rated each partner's mate appeal for short‐ and long‐term relationships. Across both sexes, narcissism was positively associated with mate appeal for short‐ and long‐term relationships. Further analyses indicated that these associations were due to the shared variance among narcissism and extraversion in men and narcissism and physical attractiveness in women, respectively. In women, psychopathy was also positively associated with mate appeal for short‐term relationships. Regarding mating preferences, narcissism was found to involve greater choosiness in the rating of others' mate appeal (but not actual choices) in men, while psychopathy was associated with greater openness towards short‐term relationships in women.

Men's strategic preferences for femininity in female faces

Several evolutionarily relevant sources of individual differences in face preference have been documented for women. Here, we examine three such sources of individual variation in men's preference for female facial femininity: term of relationship, partnership status and self‐perceived attractiveness. We show that men prefer more feminine female faces when rating for a short‐term relationship and when they have a partner (Study 1). These variables were found to interact in a follow‐up study (Study 2). Men who thought themselves attractive also preferred more feminized female faces for short‐term relationships than men who thought themselves less attractive (Study 1 and Study 2). In women, similar findings for masculine preferences in male faces have been interpreted as adaptive. In men, such preferences potentially reflect that attractive males are able to compete for high‐quality female partners in short‐term contexts. When a man has secured a mate, the potential cost of being discovered may increase his choosiness regarding short‐term partners relative to unpartnered men, who can better increase their short‐term mating success by relaxing their standards. Such potentially strategic preferences imply that men also face trade‐offs when choosing relatively masculine or feminine faced partners. In line with a trade‐off, women with feminine faces were seen as more likely to be unfaithful and more likely to pursue short‐term relationships (Study 3), suggesting that risk of cuckoldry is one factor that may limit men's preferences for femininity in women and could additionally lead to preferences for femininity in short‐term mates.     

Incorporating geographic distance into mate preference research: Necessities and luxuries, 2.0

This study (N = 370) examined mate preferences in men and women using the budget allocation paradigm across traits typically studied and the value placed on geographic proximity or propinquity. Importantly, traditionally studied preferences (i.e., physical attractiveness and social status) were seen as priorities, whereas the novel trait of distance was a luxury, suggesting that people were willing to travel to find a partner who satisfies their more important mate preferences. Men valued a short‐term mate who was close to them more than women did. Prior work on mate preferences was replicated in their context‐specific nature as per evolutionary models of mate choice.     

Cooperation as a signal of genetic or phenotypic quality in female mate choice? Evidence from preferences across the menstrual cycle

Previous research highlighting the role sexual selection may play in the evolution of human cooperation has yet to distinguish what qualities such behaviours actually signal. The aim here was to examine whether female preferences for male cooperative behaviours are because they signal genetic or indirect phenotypic quality. This was possible by taking into account female participants' stage of menstrual cycle, as much research has shown that females at the most fertile stage show greater preferences specifically for signals of genetic quality than any other stage, particularly for short-term relationships. Therefore, different examples of cooperation (personality, costly signals, heroism) and the mate preferences for altruistic traits self-report scale were used across a series of four experiments to examine females' attitudes towards cooperation in potential mates for different relationship lengths at different stages of the menstrual cycle. The results here consistently show that female fertility had no effect on perceptions of cooperative behaviour, and that such traits were considered more important for long-term relationships. Therefore, this provides strong evidence that cooperative behaviour is important in mate choice as predominantly a signal of phenotypic rather than genetic quality.     

Identifying the ideal mate: More evidence for male-female convergence

Male and female students participated in an experiment designed to test specific hypotheses fromsexual strategies theory (Buss & Schmitt, 1993) regarding their preferences for certain personal and physical traits in a potential mate. Participants distributed 50 points among a number of trait-pairs. The items consisted of a consensually valued trait-pair, “biologically relevant” trait-pairs, and a reference to ethnic and cultural similarity. In Condition 1 participants distributed the points among the trait-pairs without any additional information about the potential mate; Condition 2 participants distributed the points after being asked to assume the potential mate possessed some biologically relevant traits. Males, compared to females, assigned more points to trait-pairs signalling highreproductive value, and females, compared to males, assigned more points to trait-pairs signalling highresource potential. Male and female participants in Condition 2, compared to control participants, distributed more points among the opposite genders’ preferred traits. Discussion focused on speculation that assuming a potential mate possessed biologically relevant traits increases the desirability of other traits related to the solution of common and genderspecific long-term mating problems.     

Breadwinner Seeks Bottle Warmer: How Women’s Future Aspirations and Expectations Predict Their Current Mate Preferences

Contemporary women in Western cultures are often trying to juggle careers alongside personal and societal expectations for childrearing in an effort to “have it all.” We examine the effects of this balancing act on heterosexual women’s mate selection motivations. Across three Canadian samples (n?=?360), we tested concurrent hypotheses about the desirability of both similar and complementary characteristics in a potential mate. Specifically, women’s aspirations (to prioritize career over family) and their expectations for the roles they will most likely adopt within their future partnerships (primary breadwinner and/or caregiver) were tested as key predictors of mate preferences. Although specific effects varied across samples, a mega-analysis of the combined sample and an internal meta-analysis of effect sizes from the three studies provided support for both complementary and similarity motives (controlling for gender role attitudes). Women’s aspirations to prioritize career (over family) predicted greater similarity in mate preferences, such that they placed less importance on men’s parenting qualities, more importance on their access to financial resources, and preferred a career-oriented over family-oriented exemplar. However, women’s expectations of actually taking on the breadwinner role predicted greater complementarity in mate preferences (greater desirability of parenting qualities and a family-oriented partner; with financial resources rated as less important). Our work expands current understanding of women’s decision-making processes when selecting a mate and has implications for men’s changing traits and roles.

     

A link between altruism and sexual selection: Genetic influence on altruistic behaviour and mate preference towards it

Altruistic behaviour raises major questions for psychology and biology. One hypothesis proposes that human altruistic behaviour evolved as a result of sexual selection. Mechanisms that seek to explain how sexual selection works suggest genetic influence acting on both the mate preference for the trait and the preferred trait itself. We used a twin study to estimate whether genetic effects influenced responses to psychometric scales measuring mate preference towards altruistic traits (MPAT) and the preferred trait (i.e., ‘altruistic personality’). As predicted, we found significant genetic effects influencing variation in both. We also predicted that individuals expressing stronger MPAT and ‘altruistic personality’ would have mated at a greater frequency in ancestral populations. We found evidence for this in that 67% of the covariance in the phenotypic correlation between the two scales was associated with significant genetic effects. Both sets of findings are thus consistent with the hypothesized link between sexual selection and human altruism towards non‐kin. We discuss how this study contributes to our understanding of altruistic behaviour and how further work might extend this understanding.     

Whose personality is better,mine or my partner's? Self‐enhancement bias in relationships

Previous research has documented self‐enhancement and relationship partner‐enhancement motivations, but not examined whether individuals view themselves or their partners more favorably, overall. The authors conducted three studies that revealed a general tendency to favor oneself over one's partner in direct self–partner personality comparisons. This illustrated a motivational precedence of self‐enhancement over partner‐enhancement goals. In Study 1, participants rated self‐only traits more favorably than partner‐only traits. In Studies 2 and 3, participants rated desirable traits as more characteristic of themselves than their partner, particularly when traits were more relevant to personal than relationship success. The authors also found that this self‐favoring bias was weaker (typically nonexistent) among those with higher relationship satisfaction, lower self‐esteem, or lower self‐deceptive tendencies. The authors discuss practical, theoretical, and methodological implications.     

Sex differences when searching for a mate: A process‐tracing approach

Sex differences in the extent of mate search were investigated using two sequential choice processes. In Study 1, attribute search, prior to choosing a mate or rejecting two competing mates, for either a short‐ or long‐term relationship, was explored. Men (women) seeking short‐term relationships were the least (most) likely to reject both suitors. Men acquired a greater number of attributes prior to rejecting mates. The length of the relationship solely affected men's search behaviors. Study 2 utilized a nested sequential model namely participants decided how many suitors to sample prior to choosing a short‐term mate, and how many attributes to acquire on each sampled suitor. Women sampled a greater number of suitors prior to choosing a mate. Biological sex was found to be a greater moderator of mate search than were three personality traits linked to search. Across both studies less information was acquired prior to rejecting versus choosing a mate. Copyright © 2008 John Wiley & Sons, Ltd.     

Parent‐offspring conflict in Japan and parental influence across six cultures

Previous research has demonstrated that parents and children often have conflicting mate preferences. The present research was conducted among 443 Japanese university students. Using an existing scale designed to uncover parent‐offspring conflict over mate choice, the results revealed that children perceived having a potential partner with traits connoting poor genetic quality as being more unacceptable to themselves, and having a potential partner with traits connoting low parental investment and cooperation with the ingroup as being more unacceptable to their parent. A number of sex differences emerged. The highest potential for parent‐offspring conflict existed between female offspring and their father, and female offspring also rated traits connoting low social status as being more unacceptable to their parents, particularly to the father.     

A Web Replication of Snyder,Decker, and Bersheid's (1977) Experiment on the Self-Fulfilling Nature of Social Stereotypes

Abstract

Authors instructed two groups of male participants to respond to a web personal advertisement that had a photograph of either an attractive or unattractive woman. In the physically attractiveness condition, it was found that the message was longer and contained few spelling and grammatical mistakes than in the condition where the male's participant believe that the personal advertisement came from an unattractive woman. Two undergradutates females who were unaware of the experimental conditions judged that they had more probability to respond to the male's message in the physically attractiveness condition.

比较面孔、身材和人格特质因素影响大学生配偶选择的重要性。要求被试主观判断跟目标异性进行短期和长期交往的意愿,并且向被试同时呈现两个目标,要求被试迫选更愿意跟谁交往。结果发现,男性在长期和短期择偶中均最关注面孔,其次是身材,最后是人格特质;并且男性在短期择偶中对外部吸引力的重视程度显著高于长期择偶中。女性的长期和短期择偶偏好与男性的择偶偏好存在一致趋势。由此可知在大学生的长期和短期择偶过程中,面孔漂亮起到了最大的锦上添花效果。     

Resource availability hypothesis: Perceived financial and caloric status affect individuals' height preferences for potential partners

Height is an important concern in human mate choices. Prior research indicates that people who live in areas with abundant resources differ from those who live in areas with scarce resources regarding height preferences. Based on a health‐maximizing principle, we propose a resource availability account for such differences. Compared with women's height preferences, men's height preferences are hypothesized to be more dependent on either financial or caloric resource availability. Specifically, taller females would be more preferred by males who are poor in resources than those who are rich in resources. Results from three studies supported these hypotheses. In Study 1, men from remote areas of China who had lower family income preferred taller women more than those from eastern China who had higher family income. In Study 2, men who were financially dissatisfied preferred taller women more than those who were financially satisfied. In Study 3, men with low caloric status preferred taller women more than men with high caloric status. In addition, women's height preferences in Studies 1, 2 and 3 were less determined by resource availability. These findings suggest that height preferences are changeable, depending on financial or caloric status.     

Parental monitoring,sensitivity toward parents,and a child's mate preferences

This study investigated gender differences in parental monitoring and sensitivity toward parents and the extent to which these measures can influence children's mate preferences. In 2 samples (the United States and the Netherlands), females reported experiencing higher levels of parental monitoring and being more sensitive toward their parents' feelings regarding mate choice (e.g., being more upset if their parents did not approve of their partner) than males. Individuals displaying higher sensitivity toward parents rated parental investment and cooperation, and to a lesser extent genetic quality, as being more important in a potential mate than individuals lower in sensitivity toward parents. The level of parental monitoring did not significantly predict the importance of parental investment and cooperation or genetic quality in a potential mate.     

assessing complexity: integrating being and becoming

Holistic perspectives in career development have focused attention on complexity as important for counselors using assessment techniques. Increased emphasis on subjectivity has resulted in greater focus on qualitative measures versus traditional psychometric tests. These developments reflect issues such as the idiographic‐nomothetic distinction and individuals' being and becoming. The author uses a card sort technique to show how some of these issues might be addressed in the context of seeking a more comprehensive assessment for addressing the challenge of assessing complexity. Specifically, complexity is assessed in terms of traits, unique patterns of preferences, personal constructs, idiosyncratic likes, and the potential for change.
