Human spatial behavior has been the focus of hundreds previous research studies. However, conclusions and generalizability studies on interpersonal distance preferences were limited by some important methodological sampling issues. The objective present study was to compare preferred distances across world overcome problems observed in We an extensive analysis over a large data set ( N = 8,943 participants from 42 countries). attempted relate social, personal, intimate each country...
Static photographs are currently the most often employed stimuli in research on social perception. The method of photograph acquisition might affect depicted subject's facial appearance and thus also impression such stimuli. An important factor influencing resulting is focal length, as different lengths produce various levels image distortion. Here we tested whether (50, 85, 105 mm) shape perception female male faces. We collected three portrait 45 (22 females, 23 males) participants under...
Mixed Martial Arts (MMA) is a multielement combat sport where fighters need to quickly react an opponent's movements under fatigued conditions. Research indicates that fast reaction time important in many sports, but the effect of fatigue has shown negative, null, or even positive influences on time. However, few studies have been conducted controlled setting, especially using MMA figthers, whose matches are frequently resolved split-second. Therefore, this study investigated whether acute...
Abstract Existing research indicates that the shape of various facial regions is linked to perceived attractiveness and formidability. Interestingly, little evidence shows people directly focus on these specific during judgments formidability, there support for notion levels formidability affect raters’ visual attention. We employed eye-tracking examine attention (the number fixations dwell time) in 40 women 37 men, while they assessed 45 male faces life-sized photographs The were grouped by...
Abstract Perception studies describe numerous discrete morphological facial features as important to judgements of various characteristics. Interestingly, little is known about whether people actually direct their visual attention these and how specific contexts or sex affect this attention. We, therefore, examined faces in the context intersexual (opposite-sex assessment attractiveness) intrasexual (same-sex dominance) selection. In total, 93 women 33 men rated 80 high-resolution...
Abstract The behavioral immune system, with disgust as its motivational part, serves the first line of defense in organisms’ protection against pathogens. Laboratory studies indicate that sensitivity adaptively adjusts to simulated environmental threat, but whether levels similarly change response real-life threats, such a pandemic, remains largely unknown. In preregistered within-subject study, we tested threat posed by Covid-19 pandemic would lead increased perceived disgust. perception...
Diversity in children's everyday olfactory environment may affect the development of their abilities and odor awareness. To test this, we collected data on using Sniffin' Sticks awareness with Children's Olfactory Behaviors Everyday Life Questionnaire 153 preschool children retested them one a half year later. Parents completed an inventory exposure to variety odors own Odor Awareness Scale. We controlled for effects age verbal fluency performance. found that identification discrimination...
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 confrontations based on facial cues. The factors related to the of fighting ability their relative contribution have not been investigated yet, since most existing studies employed only limited number threat potential measures or proxies. In present study, we collected data from Czech...
Olfaction plays an important role in human social communication, including multiple domains which people often rely on their sense of smell the context. The importance and its can however vary inter-individually culturally. Despite growing body literature differences olfactory performance or hedonic preferences across globe, aspects a given culture as well culturally universal individual affecting odor awareness life remain unknown. Here, we conducted large-scale analysis data collected from...
Studies in social perception traditionally use as stimuli frontal portrait photographs. It turns out, however, that 2D depiction may not fully capture the entire morphological diversity of facial features. Recently, 3D images started to become increasingly popular, but whether their differs from has been systematically studied yet. Here we investigated congruence portrait, left profile, and 360° rotation The photographs were obtained 45 male athletes under standardized conditions. In two...
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 thing, by vocalization. Previous research found that men's upper-body strength can be assessed from voice. the present study, we tested formidability perception intimidating vocalization (roars) and short utterance produced amateur male MMA fighters attending European...
Abstract Previous research has indicated that facial attractiveness may provide cues to the functioning of immune system. Mating with individuals who have a more effective system could lead higher reproductive success. Our main aim was test possible association between immunoreactivity (stimulated by vaccination) and perceived healthiness. We experimentally activated healthy men using vaccination against hepatitis A/B meningococcus measured levels specific antibodies (markers reactivity)...
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 not known whether competition outcome (a marker of a change in hierarchy) affects the hedonic quality human axillary odour. Therefore, we investigated effect winning losing on quality. We collected samples from Mixed Martial Arts fighters approximately 1 h before immediately after match....
Previous studies show that men and women attend to visual cues during the perception of others, their conscious/explicit judgments strongly agree in inferring socially relevant characteristics such as formidability attractiveness. Although adaptive evolution neural substrates facilitating this was hypothesized, relatively little is known about how systems underlie perception. Using fMRI, we explored proposed processes (e.g., activation distinct brain regions) involved assessments male...
It is well established that composite facial images are perceived as more attractive compared with individual images, suggesting a preference for heterozygosity. Similarly, there evidence preferences body odours might be linked to Here, we tested whether blending into composites would follow similar pattern observed in the perception of faces. We collected axillary odour samples from 38 individuals, which were subsequently assessed individually and two ( N = 19) or four 9) regarding their...
People tend to choose perfumes complement their body odour. As kin share some odour qualities, ability select complementary for relatives might be higher compared with selection nonrelatives. We tested this in two studies, comparing of a perfume target man by himself and either familiar but unrelated individual (girlfriend; Study 1) or relative (sister; 2). Target men applied the (own other's choice) axillae then wore cotton pads 12 hr. Collected perfume-body blends alone were assessed rater...
