Newlywed Couples' Own and Partner Sexual Disgust Sensitivities Interact to Predict Their Marital Satisfaction Through Their Sexual Satisfaction.

Sierra D Peters, Andrea L Meltzer.

Sex is integral to maintaining a satisfying long-term romantic relationship such as marriage. It is thus important to identify the factors that promote sexual satisfaction in these relationships. To this end, we examined the extent to which a crucial evolved individual difference-sexual disgust sensitivity-impacts people's sexual satisfaction and relationship satisfaction. Using a two-year longitudinal study of 102 newlywed couples (204 individuals), we demonstrated that, rather than exerting main effects, the interaction of both couple members' sexual disgust sensitivities was indirectly associated with marital satisfaction through sexual satisfaction. People whose partners' sexual disgust sensitivities were relatively similar (versus dissimilar) to their own maintained higher levels of sexual satisfaction across the first two years of marriage, which was associated with similarly elevated marital satisfaction. Not only do these findings highlight the importance of integrating evolutionary perspectives and relationship science, they underscore the value of conducting dyadic research to examine the unique intersection of both couple members' characteristics for people's relationship outcomes.

The Role of Relational Entitlement, Self-Disclosure and Perceived Partner Responsiveness in Predicting Couple Satisfaction: A Daily-Diary Study.

Octav Sorin Candel, Maria Nicoleta Turliuc.

Recent research has investigated how the sense of relational entitlement (SRE, the extent to which a person expects that his/her needs and wishes will be fulfilled by the romantic partner) diminishes couple satisfaction, but little is known about how SRE affects the daily quality of close, romantic relationships. Moreover, the evidence on how SRE interacts with other features of a satisfying relationship (such as the variables of the interpersonal process model of relationships-self-disclosure, perceived partner disclosure, and perceived partner responsiveness) is scarce. Using an electronic daily diary, we examined 99 couples (198 participants) for 7 days, with two daily measurements for each partner. We used a dyadic double intercept multilevel model, which simultaneously computes effects for men and women. We tested a model where one partner's daily couple satisfaction was predicted by their overall levels of SRE (excessive, restricted, and assertive) and by their daily and overall levels of self-disclosure, perceived partner self-disclosure, and perceived partner responsiveness. The model also included person-level interactions and cross-level interactions between the SRE types and variables of the interpersonal process model of relationships for each gender. The analysis indicated that person-level excessive SRE lowers couple satisfaction. Also, day and person-level perceived partner responsiveness and person-level self-disclosure are related to couple satisfaction, but the latter association is significant only for men. Finally, we found some significant person-level interactions that account for changes in couple satisfaction. For men, the links between couple satisfaction, excessive and restricted SRE were moderated by self-disclosure and perceived partner responsiveness, respectively, perceived partner self-disclosure and perceived partner responsiveness. For women, the associations between couple satisfaction, restricted and assertive SRE were moderated by self-disclosure, respectively, perceived partner self-disclosure. This study advances our understanding of the general implications of SRE in the dynamics of couple relationships. More specifically, it shows how SRE interacts with other couple-specific variables in shaping day-to-day couple satisfaction. The theoretical and clinical implications for couple therapy are discussed.

Female ornaments: is red skin color attractive to males and related to condition in rhesus macaques?

James P Higham, Clare M Kimock, Tara M Mandalaywala, Michael Heistermann, Julie Cascio, Megan Petersdorf, Sandra Winters, William L Allen, Constance Dubuc.

Sexual selection produces extravagant male traits, such as colorful ornaments, via female mate choice. More rarely, in mating systems in which males allocate mating effort between multiple females, female ornaments may evolve via male mate choice. Females of many anthropoid primates exhibit ornaments that indicate intraindividual cyclical fertility, but which have also been proposed to function as interindividual quality signals. Rhesus macaque females are one such species, exhibiting cyclical facial color variation that indicates ovulatory status, but in which the function of interindividual variation is unknown. We collected digital images of the faces of 32 rhesus macaque adult females. We assessed mating rates, and consortship by males, according to female face coloration. We also assessed whether female coloration was linked to physical (skinfold fat, body mass index) or physiological (fecal glucocorticoid metabolite [fGCM], urinary C-peptide concentrations) condition. We found that redder-faced females were mated more frequently, and consorted for longer periods by top-ranked males. Redder females had higher fGCM concentrations, perhaps related to their increased mating activity and consequent energy mobilization, and blood flow. Prior analyses have shown that female facial redness is a heritable trait, and that redder-faced females have higher annual fecundity, while other evidence suggests that color expression is likely to be a signal rather than a cue. Collectively, the available evidence suggests that female coloration has evolved at least in part via male mate choice. Its evolution as a sexually selected ornament attractive to males is probably attributable to the high female reproductive synchrony found in this species.

Desire, Familiarity, and Engagement in Polyamory: Results From a National Sample of Single Adults in the United States.

Amy C Moors, Amanda N Gesselman, Justin R Garcia.

Coupledom and notions of intimacy and family formation with one committed partner are hallmarks of family and relationship science. Recent national surveys in the United States and Canada have found that consensually non-monogamous relationships are common, though prevalence of specific types of consensual non-monogamy are unknown. The present research draws on a United States Census based quota sample of single adults (N = 3,438) to estimate the prevalence of desire for, familiarity with, and engagement in polyamory-a distinct type of consensually non-monogamous relationship where people typically engage in romantic love and sexual intimacy with multiple partners. Results show that 1 out of 6 people (16.8%) desire to engage in polyamory, and 1 out of 9 people (10.7%) have engaged in polyamory at some point during their life. Approximately 1 out of 15 people (6.5%) reported that they knew someone who has been or is currently engaged in polyamory. Among participants who were not personally interested in polyamory, 1 out of 7 (14.2%) indicated that they respect people who engage in polyamory. Few sociodemographic correlates emerged; no differences in prevalence were found based on political affiliation, income, religion, geographic region, or race/ethnicity. Sexual minorities, men, and younger adults reported greater desire to engage in polyamory (compared to heterosexuals, women, and older adults, respectively). Men and people with lower education backgrounds were more likely to have previously engaged in polyamory (compared to women and people with higher education backgrounds, respectively). Given that emotional and sexual intimacy is an important part of most people's lives, understanding the varied ways in which people navigate their intimate lives is critical for the fields of relationship, sexuality, and family science.

Friend effects framework: Contrastive and hierarchical processing in cheerleader effects.

Edwin J Burns, Weiying Yang, Haojiang Ying.

Cheerleader effects, group attractiveness effects, and divisive normalization are all characterized by faces appearing more attractive when seen within a group. However, it is possible that your friends could have a detrimental effect upon your attractiveness too: if these group effects arose partly as a contrastive process between your face and your friends, then highly attractive friends may diminish your attractiveness. We confirm this hypothesis across two experiments by showing that the presence of highly attractive friends can indeed make you appear less attractive (i.e., a reverse cheerleader effect), suggesting friend effects are driven in part by a contrastive process against the group. However, these effects are also influenced by your own attractiveness in a fashion that appears consistent with hierarchical encoding, where less attractive targets benefit more from being viewed in an increasingly unattractive group than attractive targets. Our final experiment demonstrates that the company of others not only alters our attractiveness, but also induces shifts in how average or distinctive a target face appears too, with these averageness effects associated with the friend effects observed in our first experiment. We present a Friend Effects Framework within which 'friend effects' is an umbrella term for the positive (e.g., cheerleader effects, group attractiveness effects) and negative (i.e., the reverse cheerleader effect) ways in which hierarchical encoding, group contrastive effects, and other influences of friends can have on your attractiveness.

Recognition of the Impulse of Love at First Sight Based on Electrocardiograph Signal.

Jin Zhang, Guangjie Yuan, Huan Lu, Guangyuan Liu.

The impulse of love at first sight (ILFS) is a well known but rarely studied phenomenon. Despite the privacy of these emotions, knowing how attractive one finds a partner may be beneficial for building a future relationship in an open society, where partners are accepting each other. Therefore, this study adopted the electrocardiograph (ECG) signal collection method, which has been widely used in wearable devices, to collect signals and conduct corresponding recognition analysis. First, we used photos to induce ILFS and obtained ECG signals from 46 healthy students (24 women and 22 men) in a laboratory. Second, we extracted the time- and frequency-domain features of the ECG signals and performed a nonlinear analysis. We subsequently used a feature selection algorithm and a set of classifiers to classify the features. Combined with the sequence floating forward selection and random forest algorithms, the identification accuracy of the ILFS was 69.07%. The sensitivity, specificity, F1, and area under the curve of the other parameters were all greater than 0.6. The classification of ECG signals according to their characteristics demonstrated that the signals could be recognized. Through the information provided by the ECG signals, it can be determined whether the participant possesses the desire to fall in love, helping to determine the right partner in the fastest time; this is conducive to establishing a romantic relationship.
