An Agent-Based Model of Sex and Sexual Orientation Differences in Short-Term Mating Behaviors as a Result of Mating Preferences

ABSTRACT Sex differences in short-term mating behaviors are well-documented in human sexuality research. Existing studies usually explain sex differences in sexual behaviors through differences in mating preferences, which is theoretically problematic. Using an agent-based model, we investigated the circumstances under which males’ and females’ differential preferences for short-term mating would result in sex differences in short-term mating behaviors. The model showed that when all individuals in a closed heterosexual population were considered, males and females had the same average number of short-term mating experiences and short-term mates even when males had stronger preferences for short-term mating. Males (vs. females) had a higher average number of both experiences and mates when analyses were limited to only heterosexual males and females who successfully participated in the mating pool (i.e., those with a non-zero number of short-term mating experiences). Moreover, when males (vs. females) had stronger preferences for short-term mating, gay males had a higher average number of experiences and mates compared to both lesbian females and heterosexual males. These results suggest that even when sex differences in mating preferences exist, the sex differences in short-term mating behaviors only occur among particular populations, or when males’ preferences for short-term mating are not constrained by those of females. Suggestions for future research in human mating psychology and behaviors were provided.

Development and assessment of the Partner Exploitation Inventory

• We create and assess the Partner Exploitation Inventory (PEI). • Items were generated using act nomination and grouped using act frequency methods. • Three components emerged: Harm-Inducing, Ego-Boosting, and Emotional Manipulation. • Differences in PEI scores based on sex and dark personality traits are reported. • The PEI will be useful in investigating partner exploitation in future work. Differences in mating preferences, strategies, and goals can lead to romantic relationship conflict. One method of addressing conflict is exploitation, which occurs when deception, manipulation, coercion, or force is used to obtain a resource that the exploited is reluctant to provide. Here we create and provide initial assessment of the Partner Exploitation Inventory, which measures the use of tactics to exploit a romantic partner. Participants ( n =172) used an act nomination procedure to generate 62 exploitative acts that may be used against a romantic partner. Next, using a new group of participants ( n =516), we grouped the acts into three components that represent different forms of partner exploitation: Harm-Inducing, Ego-Boosting, and Emotional Manipulation. Men reported greater use of Ego-Boosting and Harm-Inducing exploitation, and women reported greater use of Emotional Manipulation exploitation. Evidence for the validity of the Partner Exploitation Inventory was also found through positive associations with questionnaires measuring similar constructs. This study expands our knowledge of men's use of exploitation strategies and is the first study to directly investigate women's use of exploitation strategies. We also created a tool that can be used to examine exploitation in the future.

Materialism, wives' relative earnings, and marital satisfaction among South Korean couples: Actor and partner effects.

This study examined the relationship between spousal levels of materialism and marital satisfaction while considering the moderating role of wives' relative earnings, using the Actor Partner Interdependence Model (APIM). A total of 301 South Korean heterosexual married couples completed the survey. We found that wives' materialism had actor and partner effects on both spouses' marital satisfaction. Husbands' level of materialism was not associated with their own marital satisfaction but had a positive association with wives' marital satisfaction. The interaction between wives' materialism and their relative earnings significantly predicted both spouses' marital satisfaction. That is, the negative relationship between wives' materialism and both spouses' marital satisfaction was stronger when wives' relative earnings were higher. However, wives' materialism was not related to either partner's marital satisfaction when wives' relative earnings were low. These results can be illuminated by gender differences in mating preferences, and characteristics of materialists and South Korean culture.

Sex Differences in Mate Preferences Across 45 Countries: A Large-Scale Replication

Considerable research has examined human mate preferences across cultures, finding universal sex differences in preferences for attractiveness and resources as well as sources of systematic cultural variation. Two competing perspectives—an evolutionary psychological perspective and a biosocial role perspective—offer alternative explanations for these findings. However, the original data on which each perspective relies are decades old, and the literature is fraught with conflicting methods, analyses, results, and conclusions. Using a new 45-country sample (N = 14,399), we attempted to replicate classic studies and test both the evolutionary and biosocial role perspectives. Support for universal sex differences in preferences remains robust: Men, more than women, prefer attractive, young mates, and women, more than men, prefer older mates with financial prospects. Cross-culturally, both sexes have mates closer to their own ages as gender equality increases. Beyond age of partner, neither pathogen prevalence nor gender equality robustly predicted sex differences or preferences across countries.

Sex Differences in Mate Preferences: a Replication Study, 20 Years Later

Evolutionary psychologists have argued for evolved sex differences in human mate preferences (e.g., (Buss and Barnes Journal of Personality and Social Psychology 50,559–570, 1986; Buss American Scientist 73,47–51, 1985, Behavioral and Brain Sciences 12, 1–49, 1989, 1994). Specifically, they have suggested that men and women place different values on physical appearance, fertility, and economic stability when they choose a long-term partner (e.g., Miller 2000; Buss and Schmitt Psychological Review 100, 204–232, 1993; Fisman et al. 2006; Sprecher et al. Journal of Personality and Social Psychology 66, 1074–1080, 1994). In this short report, we replicated a seminal study that investigated preferences for potential marriage partners (Sprecher et al. Journal of Personality and Social Psychology 66, 1074–1080, 1994) to assess if sex differences in mate preferences may have converged over time due to social change via a crowd-sourced sample (n = 522). The replication was largely successful and, thus, suggests stable sex differences in long-term mate preferences in line with an evolutionary framework. However, we also found evidence for narrowed sex differences for preferences with regard to ethnicity and education. Interestingly, while the original study found no sex difference in the preference for marrying the previously married, the current study showed that women were slightly more inclined than men to prefer a previously married partner. Therefore, these findings also suggest that social change and societal norms could make long-term mate preferences flexible and influence how they develop over time.

Choosiness, a neglected aspect of preference functions: a review of methods, challenges and statistical approaches.

Animals are faced with many choices and a very important one is the choice of a mating partner. Inter-individual differences in mating preferences have been studied for some time, but most studies focus on the location of the peak preference rather than on other aspects of preference functions. In this review, we discuss the role of variation in choosiness in inter-sexual selection. We define individual-level choosiness as the change in mating propensity in response to different stimulus signals. We illustrate general issues in estimating aspects of preference functions and discuss experimental setups for quantifying variation in choosiness with a focus on choices based on acoustic signals in insects. One important consideration is whether preferences are measured sequentially one stimulus at a time or in competitive multiple-choice setups; the suitability of these alternatives depends on the ecology of the study species. Furthermore, we discuss the usefulness of behavioural proxies for determining preference functions, which can be misleading if the proxies are not linearly related to mating propensity. Finally, we address statistical approaches, including the use of function-valued trait analysis, for studying choosiness. Most of the conclusions can be generalized beyond acoustic signals in insects and to choices in non-sexual contexts.

Mating Preferences of the Gynogenetic Amazon Molly Differ Between Populations Sympatric with Different Host Species

AbstractGynogenetic species rely on sperm from heterospecifics for reproduction but do not receive genetic benefits from mating because none of the paternal genome is incorporated into offspring. The gynogenetic Amazon molly (Poecilia formosa) is a species of hybrid origins that are sympatric with one of the two parent species that provide sperm for reproduction, P. latipinna or P. mexicana. Amazons should not prefer to mate with one species over the other because sperm from both species will trigger embryogenesis, but mating preferences may be present in Amazons through other mechanisms. Amazons may prefer the more familiar species (males found in sympatry), or Amazons may prefer males with the greatest lateral projection area (LPA), a preference that is present in the parent species and may be retained within the Amazon hybrid genome. We tested association preferences of two populations of Amazons sympatric with either P. mexicana or P. latipinna. We first performed live trials to test whether Amazons preferred one host species over the other and found that neither population of Amazons showed a preference. We then tested whether Amazons preferred sympatric male (familiar) host or the male with the greatest lateral projection area (LPA) using four animated male models that varied in host species and manipulation of LPA. We found Amazons from a population sympatric with P. latipinna showed no variation in their association preference across the different models. In contrast, Amazons from a population sympatric with P. mexicana (naturally small LPA) spent more time associating with the male models that had smaller LPA, which is more familiar to this population of Amazons. We suggest that Amazons may have population differences in mating preferences, where Amazons sympatric with P. latipinna may not show mating preference for host species, but Amazons sympatric with P. mexicana may show preferences for more familiar‐shaped males.

Sex-specific conditional mating preferences in a cichlid fish: implications for sexual conflict

Conditional mating strategies enable individuals to modulate their mating behaviour depending on ‘individual status’ to maximise fitness. Theory predicts that variation in individual quality can lead to differences in mating preferences. However, empirical evidence is scarce particular in terms of variation in male and female strategies. Here, we experimentally investigated quality-dependent variation in mating preferences concerning reliable quality indicators in Pelvicachromis taeniatus, a colourful cichlid fish with mutual mate choice and ornamentation. Males as well as females were artificially manipulated in phenotypic quality by different feeding regimes. Ornamentation was connected to individual quality in both sexes. Males and females showed conditional mating strategies in different directions. Males showed prudent choice by preferring females of similar quality. In contrast to males, low-quality females preferred highly ornamented males, whereas high-quality females showed neither preferences for high- nor for low-quality males. The results suggest that individuals aim for specific benefits depending on individual quality. Furthermore, the conflicting conditional mating preferences of males and females might lead to sexual conflict, implicating a highly dynamical mating system that evolves even in absence of environmental changes.

Hair Color and Courtship: Blond Women Received More Courtship Solicitations and Redhead Men Received More Refusals

Previous research on the effect of hair color on people’s evaluation and behavior has revealed discrepant results and the real effect of both male and female hair color on their mating attractiveness has never been tested. In Study 1, female confederates wearing blond, brown, black or red colored wigs were observed while sitting in a nightclub. In Study 2, male confederates wearing different colored wigs asked women in a nightclub for a dance. It was found that blond women were more frequently approached by men whereas blond males did not receive more acceptances to their requests. However, in both conditions, red hair was associated with less attractiveness. Evolutionary theory and differences in mating preferences are used to explain the blond hair effect. Scarcity of red-haired individuals in the population and negative stereotypes associated with red hair are used to explain the negative effect of red hair.

Sex Differences in Mate Preferences in Australia: Exploring Evolutionary and Social-Economic Theories

Extensive research on sex differences in mate preferences has found that men desire the physical attractiveness of a potential partner more than do women, and women desire the status and resources potential partner more than do men. The aim of the current study was to explore these sex differences in mate preferences specifically in the Australian culture, a culture that has not yet received attention in mate preferences literature. The current study predicted Australian men and women would exhibit traditional sex differences in mate preferences. The current study also aimed to explore the effect of variation in Australian women's socio-economic status (SES) and their corresponding ratings of characteristics in a potential partner. One hundred and forty-four Australian participants completed a mate selection questionnaire and results supported traditional sex differences in mate preferences. Results also found that women's SES had no effect on desirability of status and resources, but positively related to desirability of physical attractiveness in a potential partner. Results are discussed in terms of evolutionary and social-economic theories.

Sex Differences in Mate Preference Between Two Hybridizing Species of Poeciliid Fish

When hybridization between two species in secondary contact is costly, natural selection should favor pre-mating isolation barriers. The invasive Gambusia affinis has been introduced to habitats of a closely related species, the endangered Gambusia nobilis. Although other Gambusia species readily hybridize in secondary contact, previous studies in this system found low abundance of hybrids in sympatry. To examine whether hybridization is limited by behavioral pre-mating isolation that may have evolved in allopatry, I examined each species’ mating preferences using individuals from allopatric populations in male and female visual/olfactory association preference tests as well as open mating tests with and without male–male competition. Gambusia affinis and G. nobilis males had significant association preference for conspecific females in visual/olfactory tests. Only G. nobilis females had statistically significant preference for conspecific males. In open mating tests, males of both species had lower chase times overall when in competition, but there was no difference in number of copulation attempts. Males of both species had higher copulatory success rates with conspecific females when in competition, suggesting females may exert some control over copulation success of males. These results suggest that there are differences in mating preferences between these species. This mate choice may act as a pre-mating isolating barrier to reduce hybridization in sympatry, a proposed threat to the endangered G. nobilis.

Sexual imprinting on continuous variation: do female zebra finches prefer or avoid unfamiliar sons of their foster parents?

Sexual imprinting on discrete variation that serves the identification of species, morphs or sexes is well documented. By contrast, sexual imprinting on continuous variation leading to individual differences in mating preferences within a single species, morph and sex has been studied only once (in humans). We measured female preferences in a captive population of wild-type zebra finches. Individual cross-fostering ensured that all subjects grew up with unrelated foster parents and nest mates. Females from two cohorts (N = 113) were given a simultaneous choice between (two or four) unfamiliar males, one of which was a genetic son of their foster parents (SFP). We found no significant overall preference for the SFP (combined effect size d = 0.14 +/- 0.15). Additionally, we tested if foster parent traits could potentially explain between-female variation in preferences. However, neither the effectiveness of cooperation between the parents nor male contribution to parental care affected female preferences for the son of the foster father. We conclude that at least in zebra finches sexual imprinting is not a major source of between-individual variation in mating preferences.

Homosexual Mating Preferences from an Evolutionary Perspective: Sexual Selection Theory Revisited

Studies in evolutionary psychology and sexual selection theory show that heterosexual men prefer younger mating partners than heterosexual women in order to ensure reproductive success. However, previous research has generally not examined differences in mating preferences as a function of sexual orientation or the type of relationship sought in naturalistic settings. Given that homosexual men seek partners for reasons other than procreation, they may exhibit different mating preferences than their heterosexual counterparts. Moreover, mating preferences may show important differences depending on whether an individual is seeking a long-term versus a short-term relationship. The purpose of the present study was to examine these issues by comparing partner preferences in terms of age and relationship type between homosexual and heterosexual men placing internet personal advertisements. Participants included 439 homosexual and 365 heterosexual men who placed internet ads in the U.S. or Canada. Ads were coded for the participant's age, relationship type (longer-term or short-term sexual encounter) sought, and partner age preferences. Significantly more homosexual than heterosexual men sought sexual encounters, although men (regardless of sexual orientation) seeking sexual encounters preferred a significantly wider age range of partners than men seeking longer-term relationships. These findings suggest that partner preferences are independent of evolutionary drives to procreate, since both types of men preferred similar ages in their partners. In addition, they highlight the importance of examining relationship type in evolutionary studies of mating preferences, as men's partner preferences show important differences depending upon the type of relationship sought.

The Evolutionary Psychology of Human Mate Choice

Abstract The recent incorporation of sexual selection theories into the rubric of evolutionary psychology has produced an important framework from which to examine human mating behavior. Here we review the extant empirical and theoretical work regarding heterosexual human mating preferences and reproductive strategies. Initially, we review contemporary evolutionary psychology's adaptationism, including the incorporation of modern theories of sexual selection, adaptive genetic variation, and mate choice. Next, we examine women's and men's mating preferences, focusing on the adaptive significance of material, genetic and fertility benefits, and their relationship to environmental characteristics. Following this, we consider human mate choice in relation to non-adaptive preferences. This discussion ends with a look at context effects for individual differences in mate-preferences and reproductive strategies.

Colour vision and speciation in Lake Victoria cichlids of the genus Pundamilia

Lake Victoria cichlids are one of the most speciose groups of vertebrates. Selection on coloration is likely playing an important role in their rapid speciation. To test the hypothesis that sensory biases could explain species differences in mating preferences and nuptial coloration, we studied seven populations of four closely related species of the genus Pundamilia that differ in visual environment and male nuptial colour. Microspectrophotometry determined that the wavelength of maximum absorption (lambdamax) of the rod pigment and three cone pigments were similar in all four species. Only the long wavelength sensitive (LWS) pigment varied among species, with 3-4 nm shifts in lambdamax that correlated with differences in the LWS opsin sequence. These subtle shifts in lambdamax coincided with large shifts in male body colour, with red species having longer LWS pigments than blue species. Furthermore, we observed within and between species a correlation between water transparency and the proportion of red/red vs. red/green double cones. Individuals from turbid water had more red/red double cones than individuals from clear water. The variation in LWS lambdamax and in the proportion of red/red double cones could lead to differences in perceived brightness that may explain the evolution of variation in male coloration. However, other factors, such as chromophore shifts and higher order neural processing, should also be investigated to fully understand the physiological basis of differential responses to male mating hues in cichlid fish.

Context-dependent male mating preferences for unfamiliar females

We used laboratory and field-based experiments to examine male mate choice in the promiscuous Panamanian bishop Brachyrhaphis episcopi (Poeciliidae) (also referred to as Brachyraphis episcopi). As females of this species can store sperm, males could increase their reproductive success by selectively mating with different females. To test this, males in both the laboratory and field were allowed to choose between a familiar (same tank or pool) and an unfamiliar female (different tank or pool). We compared males from streams and seasonally occurring pools to see whether lack of access to new females in pools promotes male mate choice for unfamiliarity. In addition, we chose streams and pools both with and without predatory fish to examine the influence of predation risk. In both the laboratory and the field, males attempted more matings with unfamiliar than familiar females. Field experiments showed that courtship preferences differed between males from populations with and without predatory fish: males from populations with predators were choosy only when light levels were dim, whereas males from populations without predators were choosy when light levels were brighter. Males from both streams and pools discriminated between familiar and unfamiliar females, but there were no differences in mating preferences between males from each habitat. Although the reasons for a preference for unfamiliar females remain unclear, the plasticity of this behaviour is evident. Differences in male mate choice between populations with and without predators suggest that males may face a trade-off between the costs and benefits of being choosy.

Sex differences in intra-sex variations in human mating tactics: An evolutionary approach

We assessed sex differences in the effects of physical attractiveness and earning potential on mate selection, and sex differences in preferences and motivations with regard to short-term and long-term mating. We also investigated the effect of a variable likely to produce intra-sex variations in the selection of mating tactics, self-perceived mating success. Forty-eight university students were presented with pictures and short descriptions of persons of the opposite sex varying in physical attractiveness and earning potential. Dating interest was influenced, for both sexes, by stimulus-person's physical attractiveness and earning potential, but these two characteristics interacted only for female raters. Male and female subjects showed discrepant preferences and motivations with regard to short-term and long-term mating. In addition, self-perceived mating success was related to mating tactics in males only: Males who perceived themselves as more successful, compared to males who perceived themselves as less successful, tended to prefer and to more often select short-term mating. This effect was maximized when the stimulus person was very attractive and of high earning potential. These results confirm sex differences in mating preferences, strongly suggest a proximal factor of tactic selection, and suggest that males' mating strategies may be more variable than females'.
