Dominance hierarchy is often established via repeated agonistic encounters where consistent winners are considered dominant. Human body odour contains cues to psychological dominance and competition, but it is not known whether competition outcome (a marker of a change in dominance hierarchy) affects the hedonic quality of human axillary odour. The...

Previous studies have shown that women perceive male faces with a more reactive immune system as more attractive, but whether body odor might likewise provide cues to immune function has not been investigated yet. These two studies tested a possible relationship between body odor quality and immunoreactivity (Study 1) and immune system function (St...
Article
Previous studies on various vertebrates have shown that quantity and quality of food intake affect odour attractiveness as perceived by potential mates. In humans, the quality of body odour is similarly affected by ingested foods, such as by variation in meat and garlic intake. Nevertheless, it is not known whether quantity of food has an impact on...

Facial perception plays a key role in various social interactions, including formidability assessments. People make relatively accurate inferences about men's physical strength, aggressiveness, and success in physical confrontations based on facial cues. The physical factors related to the perception of fighting ability and their relative contribut...

Previous research has indicated that facial attractiveness may provide cues to the functioning of the immune system. Mating with individuals who have a more effective immune system could lead to a higher reproductive success. Our main aim was to test a possible association between immunoreactivity (stimulated by vaccination) and perceived facial at...

Recent work has demonstrated that human body odour alters with changing emotional state and that emotionally laden odours can affect the physiology and behaviour of people exposed to them. Here we review these discoveries, which we believe add to a growing recognition that the human sense of smell, and its potential role in social interactions, hav...

CZECH ABSTRACT | Zahájení kojení je komplexní proces ovlivňovaný nejen fyziologickými procesy a chováním matky, ale i reakcemi novorozence. Při vyhledávání prsu novorozencem hrají, mimo taktilních, vizuálních a chuťových vodítek, klíčovou roli čichové podněty z mateřského mléka a sekrece žláz nacházejících se na areole. Hlavním cílem tohoto přehled...

Background and objective: Luteinizing hormone-releasing hormone agonists (LHRHa) suppress gonadal hormone production and are commonly used to treat prostate cancer (PC) in men and conditions ranging from uterine fibroids to estrogen-sensitive cancers in women. They are also used to delay sexual development in children considering gender reassig...

Behaviorální imunitní systém představuje vedle tělesného imunitního systému další obranný nástroj organismu. Jeho hlavní funkcí je detekce a vyhnutí se potenciálně ohrožujícím podnětům, jež mohou vést k přenosu patogenů. Včasná vyhýbavá reakce organismu významně snižuje energii, jež by jinak byla vydána na metabolicky náročné reakce tělesného imuni...

Mixed Martial Arts (MMA) is a multielement combat sport where fighters need to quickly react to an opponent’s movements under fatigued conditions. Research indicates that fast reaction time is important in many sports, but the effect of fatigue has shown negative, null, or even positive influences on reaction time. However, few studies have been co...

Historically, antagonistic interactions have been a crucial determinant of access to various fitness-affecting resources. In many vertebrate species, information about relative fighting ability is conveyed, among other things, by vocalization. Previous research found that men's upper-body strength can be assessed from voice. In the present study, w...

Studies in social perception traditionally use as stimuli frontal portrait photographs. It turns out, however, that 2D frontal depiction may not fully capture the entire morphological diversity of facial features. Recently, 3D images started to become increasingly popular, but whether their perception differs from the perception of 2D has not been...

Introduction. Temperament affects olfaction in cross-sectional studies. However, it is not clear whether it is linked to olfactory development. Here we examined the links between temperament and olfaction over a nearly 2-year period, expecting that children showing higher levels of negative affectivity would exhibit greater odor awareness across re...

Previous studies have suggested possible association between immune function and facial attractiveness in humans. Mating with individuals with more reactive immune system could lead to higher reproductive success and thus it is possible that visual cues facilitating detection of such individuals may have evolved. The main aim of the present study...

Olfaction plays an important role in human social communication, including multiple domains in which people often rely on their sense of smell in the social context. The importance of the sense of smell and its role can however vary inter-individually and culturally. Despite the growing body of literature on differences in olfactory performance or...

It is well established that composite facial images are perceived as more attractive compared with individual images, suggesting a preference for heterozygosity. Similarly, there is evidence that preferences for body odours might be linked to heterozygosity. Here, we tested whether blending individual body odours into composites would follow a simi...

Diversity in children’s everyday olfactory environment may affect the development of their olfactory abilities and odor awareness. To test this, we collected data on olfactory abilities using the Sniffin’ Sticks and odor awareness with Children’s Olfactory Behaviors in Everyday Life Questionnaire in 153 preschool children and retested them one and...

Předchozí výzkumy ukazují, že některé druhy obratlovců užívají pachová vodítka k posouzení dominance či bojeschopnosti ostatních jedinců. Podobně se po vystavení tělesné vůni sbírané v kompetitivní situaci lidem zvyšuje kožní vodivost, která ukazuje reakci na významné stimuly, v porovnání s vůní sbíranou v kontrolních podmínkách. Navíc pro ženy je...

Výsledky předchozích výzkumů naznačují, že existuje vztah mezi tvarem obličeje a hladinami pohlavních hormonů v průběhu vývoje jedince. Růst a vývoj obličejových rysů a především poměr obličejové výšky a šířky (fWHR) bývá spojován s hladinami testosteronu u mužů, přičemž vyšší fWHR bývá spojováno s jeho vyšším působením v adolescenci. Předchozí stu...

Previous research has suggested that some vertebrates such as rodents use odour cues to assess individuals´ competitive abilities or dominance. Similarly, it was shown that the odour of dominant males is perceived by women as more attractive and body odour collected during competition elicits higher skin conductance response compared to non-competi...

Honest advertising of individual’s formidability is supposed to prevent potentially costly physical confrontations. It can be hypothesised that several vocal characteristics could convey information about potential formidability. Previous research found association between acoustic correlates of lower pitch such as lower F0 of connected speech and...

Previous investigations showed relationship between relative facial width (fWHR) and certain behavioural measures of intra-sexual competition such as aggressiveness, formidability or number of penalties in ice hockey and soccer players. However, due to the complex nature of these measures it is not clear which of their components primarily affect t...

Human spatial behavior has been the focus of hundreds of previous research studies. However, the conclusions and generalizability of previous studies on interpersonal distance preferences were limited by some important methodological and sampling issues. The objective of the present study was to compare preferred interpersonal distances across the...

Humans produce numerous volatile compounds from different areas of the body, either as a direct result of metabolic processes or indirectly via metabolism of resident microflora. Body odors vary between individuals, partly due to genetic differences, but odors of the same individual also vary across time due to environmental influences. We discuss...

People tend to choose perfumes to complement their body odour. As kin share some body odour qualities, their ability to select complementary perfumes for relatives might be higher compared with selection for nonrelatives. We tested this in two studies, comparing selection of a perfume for a target man by himself and by either a familiar but unrelat...

V předchozích studiích byl zjištěn vztah morfologie lidského obličeje a osobnostních charakteristik jako je dominance či agresivita, dále byl prokázán její vztah se sportovními výkony jedince, fyzickou silou a úspěchem v mezi-mužské kompetici. Uvedené charakteristiky jsou pravděpodobně spojeny s působením pohlavního hormonu testosteronu (TST), kter...

Předešlé studie ukazují, že ženy preferují a vybírají si partnery podobné svému otci v různých osobnostních a fyzických charakteristikách. Tento efekt je současně pozitivně modulován kladným vztahem s otcem během dětství a naopak. Otázkou však zůstává, zda obdobný efekt můžeme očekávat i v případě tělesné vůně, na níž se dosud žádná ze studií nezam...

Z evoluční perspektivy můžeme očekávat vznik percepčních adaptací k markerům zdravotního stavu, mezi které patří i aktivovaná imunita, jež může odkazovat k probíhajícímu onemocnění. Studie prováděné na savcích nám poskytují doklad, že jedinci s probíhajícím onemocněním jsou olfaktoricky hodnoceni v kontextu pohlavního výběru jako méně atraktivní. N...

The morphology of human female breasts typical for their permanent fat deposits appears to be unique among primates. It has been previously suggested that female breast morphology arose as a result of sexual selection. This is supported by evidence showing that women with larger breasts tend to have higher estrogen levels; breast size may therefore...

The second to fourth digit ratio (2D:4D ratio), a putative biomarker of the organizational effects of prenatal levels of androgens, was previously associated with competition performance; low 2D:4D ratio is associated with better running performance and higher success rate in fencing or sumo wrestling. However, it was also proposed that, due to all...

Cross-culturally, people use fragrances which may affect the outcomes of social interactions. It has been suggested that fragrances might mask body odours or interact with them in an idiosyncratic fashion. To test these competing hypotheses we performed a series of experiments involving: i) individual body odour discrimination, ii) attribution of p...

Growing body of research suggests link between facial Width-to-Height Ratio (fWHR; bizygomatic width divided by upper facial height) and a wide range of assessed or observed characteristics and behaviour. However, these results were rather inconsistent and recent meta-analysis showed only weak effect. fWHR studies are predominantly based on photogr...
