Homogeneously depigmented sclerae have long been proposed to be uniquely human—an adaptation to enable cooperative behaviour by facilitating interpersonal coordination through gaze following. However, recent evidence has shown that deeply pigmented sclerae also afford gaze following if surrounding a bright iris. Furthermore, while current scleral d...

Since chimpanzee (Pan troglodytes) conservation often involves local human populations, conservation strategies must consider psychological factors that impact their behavior. In Budongo Forest, Uganda, for example, local communities commonly engage in snare trap (hereafter: snare) setting for wild meat. This illegal activity posits a substantial t...
Article
Full-text available
Paternal age at birth, a potential proxy of mutation load transmitted to the offspring, has previously been related to the offspring's health, biological condition and reproductive potential. As higher facial asymmetry and distinctiveness serve as putative markers of the lower genetic quality of an individual, we hypothesize that more advanced pate...

It has been proposed that women’s physical attractiveness is a cue to temporal changes in fertility. If this is the case, we should observe shifts in attractiveness during pregnancy—a unique physiological state of temporal infertility. The aim of this study was to examine how women’s facial attractiveness changes during the subsequent trimesters of...

Heart rate variability (HRV) is a widely used measure that reflects autonomic (parasympathetic) control of the heart. HRV has been linked with attentional performance, but it is unclear to what extent resting HRV is associated with both attention and attentional maintenance. In order to address this, we calculated HRV in seventy-four young and heal...

Fluctuating asymmetry (FA) is the small random deviations from a perfect bilateral symmetry in a morphological trait. It is considered as an indicator of biological quality and developmental stability of individual. Adverse environmental conditions and high levels of sex steroids may increase FA. Symmetry in women was found to be related with phase...
Article
Full-text available
According to the life history paradigm, in life-threatening conditions, sexual selection criteria are relaxed in order to increase the probability of a last resort reproduction, ultimately contributing to reproductive success. This should be reflected in loosened mating preferences — a process observed in nonhuman animals. Studies investigating thi...

The results of preliminary study conducted on a group of 109 children (58 boys and 51 girls aged 10–18 years) has been presented. The analysis of the voice fundamental frequency proves that this parameter strongly depends on the age (for boys) and on the t...
Article
Information conveyed by facial attractiveness markers such as averageness, bilateral symmetry, and secondary sexual characteristics may play an important adaptive role in human sexual selection. Nonetheless, mate choice also relies on other non-physical characteristics such as, for instance, an individual's age. Women prefer and enter in relationsh...

Full-text available
Previous works have shown that sociosexuality may affect mate choice and correspond to partners’ mate value (MV). However, there is a lack of studies that directly show how a difference between both partners’ mate values (MVD) relates to reproductive strategies. In this study we investigated a possible link between self-reported measures of individ...

A considerable amount of studies highlight positive assortative mating in terms of various aspects of mate value. However, there is a lack of studies that directly show how both partners' mate value and mate value differences are related to the satisfaction in heterosexual relationship. In the present study, the authors focused on women and analyze...
Article
A substantial number of studies indicate that human facial features such as symmetry and averageness are preferred in human mate choice. Little is known, however, about face preferences in intrapopulation or between-cultural settings as only a few studies have addressed this topic. One hypothesis is that people prefer faces that resemble faces from...

Past research on male facial attractiveness has been limited by the reliance on facialmetric measures that are less than ideal. In particular, some of these measures are face size dependent and show only weak sexual dimorphism, which limits the ability to identify the relationship between masculinization and attractiveness. Here, the authors show t...
Article
Full-text available
In between-subjects studies on two groups of women of the same age, we show that women assess male's facial attractiveness differently in the follicular (F) and luteal (L) phases. In the high conception risk phase (F), women tended to give higher scores to male faces than when they were in the luteal phase. During the five first days of the cycle,...
