The Oxford Handbook of Human Mating covers the contributions and up-to-date theories and empirical evidence from scientists regarding human mating strategies. The scientific studies of human mating have only recently risen, revealing fresh discoveries about mate attraction, mate choice, marital satisfaction, and other topics. Darwin’s sexual select...

Recognizing emotions is an essential ability for successful interpersonal interaction. Prior research indicates some links between the endocrine system and emotion recognition ability, but only a few studies focused on within-subject differences across distinct ovulatory cycle phases and this ability. These studies have demonstrated mixed results t...

Salivary steroid immunoassays are widely used in psychoneuroendocrinological studies of menstrual cycle phase, puberty, and menopause. Though manufacturers advertise their assays as suitable, they have not been rigorously validated for these purposes. We collated data from eight menstrual cycle studies across >1,200 female participants and >9,500 t...

Article
Full-text available
Research on social status competition among women suggests that underlying hormonal shifts associated with the ovulatory cycle systematically drive alterations in preferences and behavior. Specifically, it is proposed that the fertile window, marked by heightened estradiol and lower progesterone levels, is related to increased psychological motivat...
Article
Full-text available
Objective The evolutionary-contingency hypothesis, which suggests that preferences for leaders are context-dependent, has found relatively consistent support from research investigating leadership decisions based on facial pictures. Here, we test whether these results transfer to leadership decisions based on voice recordings. We examined how domin...
Article
Full-text available
Narcissistic people are exceedingly successful in conveying positive first impressions to their social surrounding, yet, they appear to be the driving force behind unfavorable long-term social and romantic relationships. Hence, a quick identification of narcissistic people may be of adaptive value for their social partners. Narcissism perception re...

Understanding how human mating psychology is affected by changes in female cyclic fertility is informative for comprehending the evolution of human reproductive behavior. Based on differential selection pressures between the sexes, men are assumed to have evolved adaptations to notice women's within-cycle cues to fertility and show corresponding ma...

Salivary steroid immunoassays are widely used in psychoneuroendocrinology to investigate the psychological effects of menstrual cycle phase. Though manufacturers advertise their assays as suitable, they have not been rigorously validated for this purpose. We collated data from eight studies across more than 1,200 women and more than 9,500 time poin...
Article
Full-text available
Multiple studies have argued that disgust, especially pathogen disgust and contamination sensitivity, change across women's ovulatory cycle, with higher levels in the luteal phase due to an increase in progesterone levels. According to the Compensatory Prophylaxis Hypothesis (CPH), women have a higher disgust sensitivity to pathogen cues when in th...
Article
Full-text available
Steroid hormones are often assessed via saliva samples, as they are noninvasive and easy to collect. However, hormone levels in saliva can fluctuate from moment-to-moment, are influenced by factors such as momentary emotional states and food intake, and some vary strongly across women's ovulatory cycle. In contrast, hormone levels in hair seem to b...

In Arslan et al. (2018), we reported ovulatory increases in extra-pair sexual desire, in-pair sexual desire, and self-perceived desirability, as well as several moderator analyses related to the good genes ovulatory shift hypothesis, which predicts attenuated ovulatory increases in extra-pair desire for women with attractive partners. Gangestad and...
Article
Full-text available
Objectives When judging a male speakers’ likelihood to act sexually unfaithful in a committed relationship, listeners rely on the speakers’ voice pitch such that lower voice pitch is perceived as indicating being more unfaithful. In line with this finding, a recent study (Schild et al. Behavioral Ecology, 2020) provided first evidence that voice pi...

Objective Hormones are often conceptualized as biological markers of individual differences and have been associated with a variety of behavioral indicators and characteristics, such as mating behavior or acquiring and maintaining dominance. However, before researchers create strong theoretical models for how hormones modulate individual and social...

Article
Full-text available
Research on links between peoples’ personality traits and their voices has primarily focused on other peoples’ personality judgments about a target person based on a target person’s vocal characteristics, particularly voice pitch. However, it remains unclear whether individual differences in voices are linked to actual individual differences in per...
Article
Full-text available
Are ovulatory cycle shifts in women's mate attraction and preferences robust? What are underlying mechanisms of potential cycle shifts? These questions are the subject of a current scientific debate surrounding the good genes ovulatory shift hypothesis. Here, we report a large, preregistered, within-subjects study, including salivary hormone measur...
Article
Full-text available
Over the past 10 years, Oosterhof and Todorov’s valence–dominance model has emerged as the most prominent account of how people evaluate faces on social dimensions. In this model, two dimensions (valence and dominance) underpin social judgements of faces. Because this model has primarily been developed and tested in Western regions, it is unclear w...

Full-text available
Facial fluctuating asymmetry (FA), presumably a proxy measure of developmental instability, has been proposed to inversely relate to vocal attractiveness, which may convey information on heritable fitness benefits. Using an improved method of measuring facial FA, we sought to replicate two recent studies that showed an inverse correlation of facial...

Objectives Although sports team members often value their teams highly, they sometimes make mistakes and thereby unintentionally put their teams at a disadvantage. Thus, they should be motivated to compensate for their mistake to resolve this discrepancy. To test this hypothesis, we studied whether professional soccer players compensate for their o...
Article
Full-text available
The existence of ovulatory-cycle shifts in women’s mate preferences has been a point of controversy. There is evidence that naturally cycling women in their fertile phase, compared with their luteal phase, evaluate specific behavioral cues in men as more attractive for sexual relationships. However, recent research has cast doubt on these findings....

Article
Full-text available
Previous research suggests that judgments about a male speaker’s trustworthiness vary due to the speaker’s voice pitch (mean F0) and differ across domains. Mixed results in terms of the direction and extent of such effects have been reported, however. Moreover, no study so far has investigated whether men’s mean F0 is, indeed, a valid cue to their...

Gangestad et al. (this issue) recently published alternative analyses of our open data to investigate whether women show ovulatory shifts in preferences for men’s bodies. They argue that a significant three-way interaction between log-transformed hormones, a muscularity component, and women’s relationship status provides evidence for the ovulatory...

Objectives Facial masculinity, as for example measured by the facial width-to-height ratio (fWHR) or the global facial masculinity index, has been associated with a vast range of behavioural traits, including dominance and aggression. Further, facial masculinity is thought to be influenced by testosterone (T) levels as an underlying mechanism. Howe...

Article
Ovulatory cycle shifts in women’s mate preferences have been documented for several physical and behavioral traits. Research suggests that, at peak fertility, women tend to prefer men with characteristics that reflect good genes for short-term sexual relationships. However, existing findings have been criticized for methodological flexibility and f...
