Trade-offs in low-income women’s mate preferences

Testing the Mate Preference Priority Model with the Profile-Based Experimental Paradigm: A Replication and Extension

OBJECTIVE

Although the mate preference priority model (MPPM; Li et al., 2002) has advanced our understanding of mate preferences, tests of the MPPM have relied on methods using text labels and thus lack ecological validity. We address this gap by testing the MPPM using Townsend and colleagues' (1990a; 1990b; 1993) profile-based experimental paradigm, which utilizes profiles comprising photos of pre-rated models to manipulate physical attractiveness as well as costumes and descriptions to manipulate social status.

METHOD

Using Singaporean samples, we conducted two studies (Study 1 n = 431, Study 2 n = 964) where participants judged the short-term and long-term mating desirability of opposite-sex profiles varying systematically on physical attractiveness and social status. We also tested whether treating these attributes as ordinal or continuous variables would be more valid.

RESULTS

Results showed broad support for evolutionary predictions of mate preferences and priorities while revealing an increased premium placed on social status in our sample. We also found that continuous operationalizations produced less inflated results.

CONCLUSIONS

The current research provides the first non-label, profile-based test of the MPPM, a well-powered replication of the profile-based paradigm, and an opportunity to observe the robustness and variations of mate preferences in a non-Western culture.

Trade-Offs (and Constraints) in Organismal Biology

AbstractTrade-offs and constraints are inherent to life, and studies of these phenomena play a central role in both organismal and evolutionary biology. Trade-offs can be defined, categorized, and studied in at least six, not mutually exclusive, ways. (1) Allocation constraints are caused by a limited resource (e.g., energy, time, space, essential nutrients), such that increasing allocation to one component necessarily requires a decrease in another (if only two components are involved, this is referred to as the Y-model, e.g., energy devoted to size versus number of offspring). (2) Functional conflicts occur when features that enhance performance of one task decrease performance of another (e.g., relative lengths of in-levers and out-levers, force-velocity trade-offs related to muscle fiber type composition). (3) Shared biochemical pathways, often involving integrator molecules (e.g., hormones, neurotransmitters, transcription factors), can simultaneously affect multiple traits, with some effects being beneficial for one or more components of Darwinian fitness (e.g., survival, age at first reproduction, fecundity) and others detrimental. (4) Antagonistic pleiotropy describes genetic variants that increase one component of fitness (or a lower-level trait) while simultaneously decreasing another. (5) Ecological circumstances (or selective regime) may impose trade-offs, such as when foraging behavior increases energy availability yet also decreases survival. (6) Sexual selection may lead to the elaboration of (usually male) secondary sexual characters that improve mating success but handicap survival and/or impose energetic costs that reduce other fitness components. Empirical studies of trade-offs often search for negative correlations between two traits that are the expected outcomes of the trade-offs, but this will generally be inadequate if more than two traits are involved and especially for complex physiological networks of interacting traits. Moreover, trade-offs often occur only in populations that are experiencing harsh environmental conditions or energetic challenges at the extremes of phenotypic distributions, such as among individuals or species that have exceptional athletic abilities. Trade-offs may be (partially) circumvented through various compensatory mechanisms, depending on the timescale involved, ranging from acute to evolutionary. Going forward, a pluralistic view of trade-offs and constraints, combined with integrative analyses that cross levels of biological organization and traditional boundaries among disciplines, will enhance the study of evolutionary organismal biology.

Influence of Resources on Cue Preferences in Mate Selection

According to the research on the influence of resources on mate selection, the amount of financial resources affects an individual’s choice of “luxuries” and “necessities” among mate selection cues, while the amount of time resources affects cue diversity. However, for a long time, researchers only paid attention to the impact of financial resources and ignored the role of time resources. Therefore, this paper draws lessons from the relevant research on the influence of time on decision-making and proposes to study mate selection from the perspective of decision-making. Additionally, current research concerning the influence of resources on the choice of a spouse focuses more on results and neglects to examine the process. Therefore, based on the relevant theories, this paper makes several theoretical assumptions regarding the influence mechanism of resource availability on mate choice decisions, gender differences, and the actor-partner effect.

Netflix and Chill? What Sex Differences Can Tell Us About Mate Preferences in (Hypothetical) Booty-Call Relationships

The booty-call relationship is defined by both sexual characteristics and emotional involvement. In the current study, men's and women's preferences for a booty-call mate were explored. Men and women were predicted to exhibit different mate preferences depending on whether they considered a booty-call relationship a short- or long-term relationship. Participants ( N = 559, 74% women) completed an anonymous online questionnaire, designing their ideal booty-call mate using the mate dollars paradigm. Both sexes considered the physical attractiveness and kindness of a booty-call mate a necessity, expressing both short- and long-term mate preferences. The current study highlights the need to explore mate preferences outside the dichotomy of short- and long-term relationships, providing evidence of a compromise relationship.

The Relations Between Parental Socioeconomic Status, Personality, and Life Outcomes

Studies have shown that cognitive ability is correlated with parental socioeconomic status (pSES). However, little is known about the correlation between personality and pSES. To better understand this relation, we conducted a meta-analysis of the correlations between pSES and personality traits and temperament dimensions. The correlations were generally very small with the exception of the correlation between pSES and openness to experience. Our results were replicated in a large ( N = 2,183,377) data set of self-reported personality scores collected online. Using this data set, we also examined the interaction between pSES and personality on attained education and socioeconomic status. We found evidence for the resource substitution hypothesis, which proposes that personality compensates for background disadvantage.

Physical Attractiveness, Attitudes toward Career, and Mate Preferences among Young Chinese Women

We examined young Chinese women's mate preferences as a function of their self-perceived attractiveness and career attitudes. A total of 264 young Chinese women rated their own attractiveness, reported their attitudes toward career, and rated the importance of 20 mate characteristics. The characteristics encompassed four facets that individuals typically consider when seeking a long-term mate: good-genes indicators, good investment ability indicators, good parenting indicators, and good partner indicators. We found that both self-perceived attractiveness and attitudes toward career were positively associated with the importance attached to several of the characteristics. Moreover, women who had high career focus but low self-perceived attractiveness attached more value to intelligence, ambition, and industriousness than women who had low career focus but high self-perceived attractiveness; women with low career focus but high self-perceived attractiveness attached more value to physical attractiveness in a mate than women with high career focus but low self-perceived attractiveness. We discussed the limitations of our research and directions for future research.

Men’s Social Status and Attractiveness

Research has found that, for long-term dating, women value men with greater financial resources and higher status, while for short-term dating they value men with greater physical attractiveness. However, there are discrepant results for both long- and short-term dating. As most of the previous studies used only questionnaires, we conducted a field experiment to evaluate women’s receptivity to men’s date requests. Young male confederates who ostensibly had high, middle, or low incomes, depending on the experimental condition, asked young women walking down the street for their phone number. We found that men’s financial resources were positively associated with compliance with their request. Evolutionary theory proposing that women select men with greater resources for them and their offspring is used to explain the results.

Political leanings vary with facial expression processing and psychosocial functioning

Conservative, Republican sympathizers show heightened threat reactivity, but greater felt happiness than liberal, Democrat sympathizers. Recent evolutionary models interpret these findings in the context of broader perceptual and expressive proclivities for advertising cues of competency (Republicans) and trustworthiness (Democrats) to others, and in ways that facilitate the formation of distinct social networks, in coordination with individuals’ life histories. Consistent with this perspective, I found that Republican sympathizers were more likely to report larger social networks and interpret ambiguous facial stimuli as expressing more threatening emotions as compared to Democrat sympathizers, who also reported greater emotional distress, relationship dissatisfaction, and experiential hardships. The findings are discussed in the context of proximate and ultimate explanations of social cognition, relationship formation, and societal cohesion.

A socio-relational framework of sex differences in the expression of emotion

Despite a staggering body of research demonstrating sex differences in expressed emotion, very few theoretical models (evolutionary or non-evolutionary) offer a critical examination of the adaptive nature of such differences. From the perspective of a socio-relational framework, emotive behaviors evolved to promote the attraction and aversion of different types of relationships by advertising the two most parsimonious properties of reciprocity potential, or perceived attractiveness as a prospective social partner. These are the individual's (a) perceived capacity or ability to provide expedient resources, or to inflict immediate harm onto others, and their (b) perceived trustworthiness or probability of actually reciprocating altruism (Vigil 2007). Depending on the unique social demands and relational constraints that each sex evolved, individuals should be sensitive to advertise "capacity" and "trustworthiness" cues through selective displays of dominant versus submissive and masculine versus feminine emotive behaviors, respectively. In this article, I introduce the basic theoretical assumptions and hypotheses of the framework, and show how the models provide a solid scaffold with which to begin to interpret common sex differences in the emotional development literature. I conclude by describing how the framework can be used to predict condition-based and situation-based variation in affect and other forms of expressive behaviors.

Sex Differences in Affect Behaviors, Desired Social Responses, and Accuracy at Understanding the Social Desires of Other People

I recently proposed a socio-relational framework that suggests that phenotypic variation in the expression of discrete affect behaviors (e.g., expressed anger vs. sadness) may reflect two basic dimensions of behavioral response. The first dimension is the motivation to selectively attract or avoid interactions with different people. The second dimension is the behavioral display of either personal capacity or trustworthiness cues, often through the expression of dominant and submissive behaviors, respectively (Vigil, in press). Sex differences in affect behaviors (e.g., externalizing vs. internalizing displays) may reflect developmental sensitivities to advertise capacity and trustworthiness cues somewhat differently, due to the unique social dynamics and relational constraints under which males and females evolved. In this study, I use a series of self-report questionnaires to examine two basic assumptions of the framework. The first assumption is that sex differences in nonverbal affect behaviors (aggression vs. crying) reflect the desire for, and are effective for causing other people to either avoid or comfort the individual, respectively. I hypothesized that males would report a greater likelihood of responding to various distress moods with aggressive, rather than crying behaviors, and that males would desire, and believe male peers similarly desire distancing responses from others when feeling these moods. Instead, females were hypothesized to report more crying behaviors, and to desire, and believe female peers desire more comforting responses from others. The second assumption is that people are more accurate at inferring the desired social responses (i.e., to be left alone or comforted when experiencing distress) of same-sex, rather than opposite-sex peers. I hypothesized that people's beliefs of same-sex peers are more similar to the self-reported desires of the male and female participants, themselves, than their beliefs of opposite-sex peers. The results are consistent with the first assumption, but show that only men were more accurate at inferring same-sex, rather than opposite-sex desires. In general, the findings are consistent with the socio-relational framework that suggests that humans may have evolved specialized expressive behaviors and interpersonal styles for communicating and interacting with same-sex affiliates.
